  1. Hi everyone, I’m new to this forum and I just want to get a good idea of how many miles everyone’s getting out of there 14-18 5.3’s / 6L80 combos and what type of maintenance y’all are doing to get there. I have 90,****** now on my 2016. I follow my service schedule to a T. Trans fluid and filter every 22,500 and engine oil every 4000. What’s everyone else do to get there trucks up to high mileage
  2. Wondering if anyone has had similar issues. I’ve had multiple problems out of my 2020... only has 9,000 miles and purchased in August. I’ve had nothing but issues with the dealership saying they can’t replicate, etc. I have to hold my steering wheel slightly to the right to drive straight. I’ve checked the tire pressure, tires have been rotated at dealer. I’ve heard of people having alignment issues straight from the dealer. I’ve drove it in different lanes, highways, back roads all the same. It’s like I have to constantly correct the steering. If I let the wheel go it goes straight for a short distance but then I have to correct again. Just doesn’t drive as smooth as when I first bought it and seems like the steering vibrates some. Any ideas?
  3. I have a lot of questions for anyone that has done the on3preformance kit. What modifications did you have to do/ move things out of the way? How much power did you make in stock fueling? How long did it take u to install? And any tips before buying/ installing?
  4. GM is presently leaking information on their 2020 and 2021 trucks, specifically Sierras and Silverados. Wow, they look beautiful ............ but the body work hides a truck full of problems. I think they need to take a step back and reevaluate the crap they are throwing our way. Their adds promote all kinds of wonderful technology both mechanical and electrical. It all sounds so wonderful, in an idealistic way ... but it just doesn't all work as promised. Our VERY EXPENSIVE trucks are nothing more than dolled up scrap metal. Our engines are failing prematurely, brake systems continue to fail, ProTail Gates don't operate as promised and leak every time it rains. Even simple things like a simple back up cameras fail to initiate on a regular basis. Our computer screens exhibit either the blue screen of death or a totally black screen. The servicing dealers scratch their heads as they don't have the answers we all need. I spoke with the manager of the GMC dealer on Long Island where I purchased my Sierra SLT and his exact words were, "GM is putting too much technology into these vehicles. Technology that is not proven, tested or properly supported. ..... ( he went on to say ) They ( GM ) build them and we "try" to fix them. We don't know what to do or how to do it" My own truck is 5 months old and I have not had one week of trouble free use. I get calls from the GM Customer support line on a weekly basis asking what's happening and I tell them about my woes. AND NOTHING HAPPENS. I want my truck fixed once and for all, I want my warranty extended. On no less than 5 occasions I have made appointments to have my Sierra serviced, only to drive 35 mile to my dealer and find out they don't have a technician available, or I'm given some other lame excuse as to why they can't honor their appointment obligation. What is the purpose of making an appointment weeks in advance if this continues. How many of you are undergoing the same or similar experiences. Please use this forum " Lipstick On A Pig" as your thread to vent. This is in hopes that someone at GM may wake up and start to care.
  5. How many 2019 GM truck owners following this forum have actually read their manuals? Not just a section here or there, but the entire manual? I am wondering this because I have been following the new generation of GM trucks since the first announcements were made. I read many rave reviews, and watched all the online reviews and comparisons on the new trucks prior to placing an order during the 1st week of December. As time passed, and the new trucks were rolling out of the dealership doors in large numbers, more & more "issues/problems" started to pop up in the forums. These trucks are sophisticated well beyond any previous generations. The systems in my loaded '15 Camaro SS pale in comparison to what's in these new trucks. Our '19 LTZ CC with 6.2, 10-speed, Max Towing, Performance Upgrade, and Trailering Camera packages is due in this week, but I downloaded an owners manual from the Chevrolet website so that I could start to familiarize myself with how everything worked. The Chevy & GMC websites also have many instructional videos that show you just how everything works, and how different systems integrate with each other. Much to my surprise, at least 2/3rds of the forum complaints with the new truck can be attributed to owners being unfamiliar with systems and settings. In many cases, the owner has a choice of what systems they want operational, and several choices of how they want them to function. Many of the ERROR messages were simply due to owners not following the instructions in the OM. What made things even worse was their dealer being just as unfamiliar, trying to troubleshoot a "problem" that wasn't a problem, just simply operational ignorance on the part of the owner and their dealership. Maybe GM should have stepped up their dealer training, and dealerships should step up their customer training. One dealer near us holds monthly new vehicle training sessions. The new trucks have also had their share of genuine issues, but a thorough understanding of the manual may have helped some of those owners to better understand how each system is supposed to operate, which may help the dealer troubleshoot the problem. These trucks are much closer to the Jetsons than the Flintstones. BEST OF LUCK WITH YOU NEW TRUCKS!
  6. 2010 Chevy Silverado So I’ve just bought this truck, and when I try to start it the starter will sometimes stay on after the Motor fires for a few seconds. Then it has a very uneven idle. THEN when I rev the engine it wil rev up then drop down below normal idel and almost stall. This will go away if the truck is warm. Now the only thing I have done since getting it is to pull the pipe off of the purge valve next to the fuel tank because it is broken. I’ve ordered a new purge valve and will install it as soon as it gets in. Is it possible that this is causing some sort of low fuel pressure or something? Has anyone else has issues like this?
  7. Curious to know who in this forum has the highest mileage truck. Just took delievery of my new 2018 truck with the 5.3 V8 and 6 speed tranny and wondering how long I should expect it to last? Coming from a Toyota with about 350k kms I have set the bar pretty high haha. Feel free to post the year of your truck with the # of miles and what repairs/replacements you have done to date. Trying to get a little thread going about mileage and what people have been able to get. Since this is a 2014 forum I'm not expecting massive numbers, but I know some of my friends with Rams that have had engines and transmissions break down at 50k-80k kms (moment of silence for Ram owners) Ford seems to be doing a bit better in terms of major issues. If there's already a thread regarding this issue please redirect me to that one
  8. Hello all! Last February (2015) I bought my GMC Sierra WT with the io3. Since day 1 I have had problems with getting my phone to connect via USB and when it does it will sometimes skip like a vinyl record. Which I don't understand, but when I took it to the dealership they said it was the feature that turns up the volume with speed. I turned it off like they said, but no luck. In June of 2015 the Radio when completely black. After days of driving without a radio I unplugged the battery and it came back on. It happened again on Monday on my way home from work so I decided to take it to the dealership on Tuesday and they said the only thing they could do was unplug the module and let it go dead and plug it back in. I was fine with that because I figured it would be a once in a while thing and I went on my way. Yesterday I happened again and so I am back at the dealership. I am getting really tired of this. Does anyone know why this is happening or what a fix is? My dealership is clueless. Thanks in advance!
  9. Hi guys, I have a 2003 Silverado 4x4 with a 4.8 and 3.73s and auto trans. My catalytic converters were very plugged up and I ended up cutting them open, removing all of the material inside, and welding them back together. The truck has run much better since doing this. The problem is, since doing this i have been getting about 13.8-14 mpg with it. This is driving the same route i had been getting 16-17mpg previously. I am thinking that this has something to do with the fact that i left the o2 sensors in place. I am looking for a relatively inexpensive fix/ improvement for this, because this is just a rusted out daily driver truck with 160k that I don't really want to put a ton of money into. I wanted to see if anyone had any experience with this before I tried a few of my ideas. Any advice would be appreciated. Also, i am aware that this is technically illegal, but there are no emissions tests in my state, so running no cats is not a huge issue for me. thanks
  10. Hey there I am a proud owner of a 2016 Chevrolet Silverado. The issues I wanted to discuss is the new technology in the truck. What I'm referring to is the E assist system. Only 500 of these were released in California, I own one and love my truck but I believe this system is making the truck drive weird. I'm not sure if it's because it's trying to improve fuel economy or just faulty but when I am coming to a stop I can feel a clunk almost like I was rear ended, I can also feel it when taking off and it's annoying. I wanted to see if any of you have had similar problems in your truck and any advise you had or your experience. I brought this issue to the dealer twice and both times they found issues but none with the e assist system or transmission they claim. I have posted a link to a video of what happened on my last experience to my local dealer. Thanks for any help.
  11. I have a1999 Silverado 2500 4x4 6.0 that I just got running again it has been sitting for 2 years because my girls dad was going through some rough time and didn't really care now 2 years later he is in no shape to be under a hood or on his back messing with the thing anyways I needed a vehicle and he said if I could get it running I could use it I went and bought a can of sea foam a 10gal gas can with gas and battery put everything in/on and it started right up like it was nothing I was like sweet since then witch was 2 days before this post ive don a oil change wit 10w30 Castrol edge high millage and k&n oil filter a much needed bath all new lights toped off dexcool, power steering, witch is leaking but the whole reason I was making this post was when I stop at nights 2 things happen AND ONLY SOMTIMES the gas peddles feels like its getting stuck when I go to APPLY presser but not on release and it idles funny but if I put it in natural and rev it the put it back in gear it will idle normal the rest of the time till the light turns green but at the next light it may or may not do it what do you think it could be
  12. Help anyone!! A problem with my 2016 Canyon purchased new June 2016 (15000 mi). Thursday(12/21) a.m. I drove to grocery, picked up a few items and returned. Normal right? Yesterday tried to start vehicle, dead clicks. Got battery charger out on start and it started fine. Drove around for 1 1/2 hours normal local driving. Stopped at restaurant and turned off truck. 20 minutes later, truck battery is dead. Called for help, jump started, and returned home. Put on trickle battery charger over night and tried to start again this morning---dead again. Same as yesterday. This time I noticed on info screen a Status message : "Waiting for Update Media" (I am including a photo) Anyone experience this issue? Can't believe a battery is dead after only a year one-half. I have appointment at dealer ship next Wednesday....(of course it's the Holidays!!!) Thanks for any help. Dennis
  13. Hi everyone, Here is my story : I bought a brand new GMC SIERRA 2015 ,5.3 l engine "ECOTECK",6 speed ,3,42 ratio, in November 2015 .,an sle trim,Kodiak edition and I was very happy with it for a couple of weeks until I realized there are some spots in the paint on the hood and roof .I went back to the dealership and they offer to paint it(the roof and the hood)and they did a good job I would say. But this was the beginning of my nightmare : After a few months the BCM (body control module ) ceased to work ,the car start shifting the gears abnormally and I lost the front lights on my way back from the cottage in a night at 300 km away from my home .imagine how i drove back to home from the middle of nowhere ,only with the fog lights !!!but the dealer said they fix the problem changing the BCM Then the car start burning more gas then it use to .I use to maintain a very good gas economy around 11.3 to 12 liter per 100 km on hwy and around 14 mixt on the city and after they change the BCM the gas consumption gradually increased and now after 2 years and about 60000 km I can`t go lower than 14.6 on hwy (100-110 km/h speed) and 17,6 mixt in the city. Nobody could fix it and of course they always said everything is in parameters and looks good After about a year my transmission ceased in a middle of a hwy right after they replaced the hydraulic pump inside the transmission !!!! can you believe this??? If everything were good why did they change the pump inside the transmission, and this after I complaint about the hard and kicking shifting I have when I press the gas pedal in a slow driving in a traffic hwy (that time you let the car slowly move without pushing the gas pedal then after the car in front of you go and you try to keep up with the traffic ) .So they rebuild a one year old new transmission but the kick shifting they never fix it because they never admit officially is there, even everybody feel it and they said is a KIND of normal!!! Then after my infotainment system freezes up and blocked then they had to replace it .the whole radio unit with the GPS and all After another few months the differential start clinking and roaring and they rebuilt that too and now is really noisy when is cold and if I drive it in autotrack mode I barely hear the music at the radio inside the truck(the mechanics at the dealer ship always tell me that I`m not suppose to drive in auto mode !!!!! because it wears the transmission components !!!! well why the heck did I pay extra 5000 $ for this feature if I`m not suppose to use it ????) just dumb I guess !! So now I`m driving this 53000$ piece of steel ,burning my money on gas ,feeling every gear shift in the transmission kicking my butt when I`m decelerate for the next 5 years because I did the mistake of my life to buy this GM piece of ...steal for 7 YEARS. DUMB AGAIN! Well if this is the GM PRECISION which the GM ENGINEERS CLAIM IT IN THOSE advertises on tv I have to say they got the wrong word they should say GM UNRELIABILITY !!!! It is probably a bad batch what I got ,A LEMON let`s face it, but nobody whatsoever officially admit it in CANADA (once I called the GM North America in the states, they check my VIN and they said there are way to many problems with this truck in such a short time and something has to be done with it ,they transfer me to the Canadian GM customer service(ambassadors!!!!) and here we are again ...nothings wrong again all the reports are in parameters go to the dealership bla,bla ,bla ,zero,zero ,zero) and everyone try to get rid of it by saying everything works in parameters PS: I FORGOT TO MENTION THAT WHEN THE TRANSMISSION CEASED AFTER 5 KM AWAY AFTER I PICKED IT UP FROM THE DEALERSHIP , I CALLED THEM AND THE SHOP FOREMAN AND THE TRANSMISSION SPECIALIST CAME RIGHT AWAY ,THEY PLUGGED IN THEIR LAPTOPS AND THEY COULD NOT FIND ANY ERROR CODE ON THE TRUCK ,SO THEY SIT ON MY TRUCK REV THE ENGINE SHIFTED ON DRIVE MODE AND NOTHING HAPPENED THE TRUCK DIDN'T MOVE THE MOTOR REVVING AND THEY ASKING EACH OTHER WHY THERE ARE NO FAULTY CODES SHOWING UP !!!!!! MY QUESTION IS ,ONLY SOME OVERSEAS CAR MAKERS ARE CHEATING WITH THE SOFTWARES OR EVERYONE IN NORTH AMERICA DO ? and what I did wrong in this world to pay this price for this piece of "steal"? If anyone faces this problems or some of them please give me a shout ,maybe I`m not the only guy with such a bad luck to pick a pickup truck
  14. Hello, I have a 2003 silverado 1500 4x4 4.8L with a reman 4l60e that has approx. 11,000 miles on it. The problem i am having started after the trans had 9k on it. After the truck has been driven if it is shut off or idled for a few minutes it will not accelerate or shift normally. The trans is not slipping, the rpms just increase very slowly. It shifts at high rpms and usually very suddenly unles you let off on the gas to shift. This happens through all gears and it will completely go away and shift normally after a few minutes of driving. Also, if has been idling for a few minutes the rpms will go down to abt 450-500 then jump back to abt 650 and the truck will have a shudder as though it is trying to give power to something while just sitting there. It does not make any difference if it is in gear or park. This has never happened taking off with the trans cold and it has no problems with stop and go traffic only after idling or being shut off. It occasionally has a clunk while this is happening. Any suggestions would be greatly appreciated. Thanks
  15. Hi I'm brand new here but I've been a frequent snooper but I've finally come to a problem I can't find discussed before. The other day while driving my check airbag light came on it comes and goes but never stays for more than a minute. So thinking it had to be a sensor I went to oriellys and had my error codes checked only to reveal much more problems than I expected. The codes were: p0237(which I have had sinse I replaced my fuel pump so I think it's just faulty especially because the fuel gauge hasn't been right either i got another replacment I haven't had the time to install though),P0480,P0463,P0455,P0332,P0327,C0040,C0035,U1041, I think it pulled up 14 total codes but many were duplicates I think he said. my truck a SCSB 4.8 with the work trim 2005 model and just under 145,000 miles The oriellys guy suggested it may be a failing ECU and after a little research I'm thinking he may be right but I'd just like to see if any of y'all might have some ideas. Also the lights flicker like they did before I replaced my alternator and the voltage jumps around on the needle like crazy but I think I may have just picked up another faulty part butluckily that can be replaced under warranty. Other than the flickering lights the truck doesnt show any obvious signs of problems. Any and all help will be greatly appreciated needless to say it ruined my evening yesterday hah
  16. I have a 17 with a 6.2. It's left me stranded two times. 4800 miles. Problem is when I turn the key on I get stabilitrac failure/ power steering failure/ trailer brake failure/ low washer fluid(it's full). I have abs light, CEL, traction control light on. The screen goes to back up camera (in park). Also turn signals in mirror will stay illumanted. It'll start run for 30 secs and sputter and die. Then it'll just turn over. Wait for a tow truck and after the hour or 2 wait I'll get in to put it in N and everything goes back to normal besides CEL. Starts/ drives everything is back to normal. First vist pulled ecm codes and replaced the ecm. Got about 30 miles and 2 days and exact same problem again. Stranded until wrecker then cleared up and could start and drive. Any ideas? I'm nervous to take it anywhere. Only mods is MIT tube and catch can.
  17. Hey Guys, I have had my 2015 Sierra for a year and a half now and I cannot stand how the truck shifts through the gears. I have been researching the forums for different fixes or something to help make the truck drive smoother. Long story short, I find that the Range AFM v4 disabler is the best solution available that avoids voiding my warranty. I do not use my truck as my primary vehicle and only put about 7,000 miles on it a year, so I do not want to void my warranty far before it expires considering all the quirks, Direct injection, and other things the warranty could save me $thousands if something breaks. I find that the truck drives around town much smoother without it going in and out of v4/v8 modes and the trans does a much better job managing city driving. So what is the major downfall of the Range AFM Disabler? It drains the battery, especially for someone like me who only drives on weekends. Between Christmas and New Years I had the time to figure something out. In our truck one of the pins in our OBD2 connector provide a constant 12v, which the RangeAFM uses for power. I came up with a relay design that only provides power to this obd2 pin only when the ignition is on, theoretically preventing the RangeAFM from draining my battery when the truck sits. ***Please beware this is a mod I decided to do to my truck and so far I have not had an issues. Modifying your own truck is your responsibility, not mine.*** Some Key points about the mod: 1. Provides the same power source as always, but only allows the OBD2 pin to access the power source when ignition is on. 2. I have an optional switch that will provide the original constant power to that pin in the OBD2 plug. The reason I did this is because I have dealer oil changes and I want everything to operate as the truck is designed to when they connect to my OBD2 port. The switch bypasses the relay control, therefore allowing factory operation. Before my dealer visits, I removed the RangeAFM, and flip the switch. You can place your switch anywhere, mine is hidden. 3. When cutting the wire from pin 16, I soldered and heat shrink my connections, and wrap it back up with the same fabric tape GM uses. The reliability of this mod depends on your ability and skills. 4. Not that this is a big deal, but when I get my GMC email/report every month it does not show there are issues since the RangeAFM is off while the truck is sitting. Thanks again to everyone on the forms for your input that led me to this decision. When my warranty is up I cannot wait to program/tune the truck, but for now I am happy with these results.
  18. Hey guys I am having some problems with my truck and would like to see what you think. The truck is a 2015 GMC Sierra 1500 Denali. It is currently at the dealership for repair. I took the truck in for a sunroof leak on August 9. They diagnosed it as a bad seal and ordered a seal and new head liner, but had me drive it home. The leak was causing electrical problems so I parked the truck in my garage and carpooled to work. The parts arrived at the dealership and I brought the truck in on the 15th. They tell it will be done Tuesday at the latest, which is the next day. Wednesday comes and I haven't heard from them so I call. They won't answer my questions at first then tell me it'll be done the next day. Well come to find out on the 18th they misdiagnosed and it needs a whole new sunroof assembly. Guess what? GM doesn't have one in stock and will let me know by close of business the next day when they can get one. That doesn't happen either. So today, August 22, they call me at 1130 to say it won't be in stock until September 8. So at this point I am pretty annoyed of driving 6-cylinder work truck when I bought a brand new Denali. My truck spent 28 days last year in the shop for transmission problems and another week for the steering wheel heater going on the fritz and making it almost untouchable. The rep and I decide that the buyback program is reasonable next step since my truck is breaking so often. She calls and the DMA denies the claim. My response at 1230 is fine the truck will meet the Arizona lemon law requirements when the part arrives. Magically at 1300 the dealership service manager deems that a different part will work. I think it is convenient timing that when they cannot get the correct part for weeks and have no other option the word lemon comes out they find something else that works. What do you guys think? My truck will be down for at least 3.5 weeks before they can install this substitute part. Putting it out of service for almost 9 weeks in 20 months of ownership. Not to mention they have not fixed my seat issues. Should I seek legal counsel? Am I out of line? Cooperate GM just tells me to talk to the dealerships customer service rep, who just happens to be the service manager calling the shots for my repairs. Thanks, -Joe H.
  19. Hello Thinking about purchasing a new GM truck. I am wondering if anyone is having any problems with their new 1/2 ton trucks. Is GM having any problems with the 6.2 Liter Eco Tec 3 engine or still having some troubles with the new 8L90E Transmission. Other troubles and their solutions would be intresting too. It would be nice to learn in advance what to expect, will it be a wonderful smooth ride. Should I expect a few fixable bumps along the way or am I entering a nightmare ride. Thanks in advance for your input. Success stories are certainly welcomed for a well rounded view.
  20. When I enable 4x4 the truck seems to have problems backing up and sometimes forward, its like I feel Im gonna break something if I force it to much so when I switch back to regular 2 wheel drive the truck kinda shakes a bit with an ugly sound. What should I look at here ? Thanks
  21. I have a 2007 V8 4.8 L Chevy Silverado 1500 LT and I turn the key to start it and sometimes nothing happens at all like the battery is dead (no dash lights, no anything). I try a few more times and nothing. Then I get back in it an hour later and it starts right up. Replaced Starter, battery is not an issue and problem still remains. Can anyone help?
  22. i recently bought a stock chevy radio with the aux jack and the usb in back and want to swap it with my stock am fm radio. i swaped them and the "locked" code popped up and i took it to the local dealer and had them reprogram it for me. the radio works and everything is functional but the volume doesn't go up all the way. the blinker sounds dont work along with the seatbelt dinger, what do i need to do?
  23. I am looking for help with my 2007 Gmc sierra 1500 Classic, the transmission had started slipping on me a few days ago, 1st gear works perfect then it gets high rpms and doesn't want to shift into 2nd I have to ease off the throttle with speed to slightly catch either 2nd or third, then even when I'm going 90 kms the rpm is at 3500.. There's slipping going on and it won't shift from 1st to 2nd.. Any Ideas what this could be ? Also my tranny fluid levels were good but the oil smelled burnt.. Thanks
  24. What is every bodies experience with the General Graber HTS 245/70-17? I have a 2013 Silverado 1500 2WD. The truck was new 4-1-2013 and it now has with 19000 miles on it. I drive 4 miles total of gravel every day and the rest is highway miles. I have had 5 flat tires with the tires in the last 10 days. One of the flats was a front tire. All of the flats were in the tread area and when the tires were removed to patch them there was nothing in the tire. No nail, no rock no nothing. I purchased a new 2010 Silverado 1500 2WD in 4-1-2010 and had the same luck with them. I talked with a General Tire Store in Nov 2010 and was told that since I had patched the tires there was nothing that could be done even though two of those tires had not been patched. I am 60 and long past the time of spinning my tires on the gravel or pavement. Has anyone else experienced this? I have been a loyal GM driver all my life but this has almost destroyed the loyalty. FYI I talked with the dealership where I bought the truck and they said I needed to see a General Tire Store or Dealership.
