Hi all, First post. Just wanted to share this story and get feedback and see if others have had a similar experience. At approximately 70,000 kms I started noticing an engine tick. At first I assumed it was some sort of direct injection noise. It got worse. Eventually I lost almost all power and I brought the truck in to the dealer for servicing. I was told that I had a bent push rod on cylinder #4. That was replaced and nothing else. I questioned why this happened and I was told it is common. At 85,000 kms the tick returned/got worse. Again I brought the truck to the dealer. Eventually (after a few arguments) they decided to replace valves/lifters on the 4 AFM cylinders, and they found another bent push rod. When I went to pick up the truck, the noise was still there. They completed further diagnostics and found scuffing on 2 pistons. They called GM and they said to replace the engine. Full engine replacement! Any thoughts, comments on this? I haven't got the truck back yet - waiting on engine to be replaced. Matt

Hi All, I am debating whether or not to cancel my extended warranty I purchased 2 1/2 years ago when I bought my 2016 Silverado LT new. Obviously, the warranty overlaps everything the manufacture is offering for the first 3 years, 36,000 miles etc. My ext warranty is 60 months (5 yrs), 100,000 miles. Covers everything Engine, Transmission/transaxcel, transfer case, electrical, Fuel, Interior, Exterior, steering, suspension, cooling, drive axle, brakes, AC/heating, and additional benefits like lockout, tow, rental coverage, trip interruption, gas supply and jump starts etc. The question is, I paid $2998 for it, but seeing that nearly I have 5 months left before my MFG warranty expires on the 3yr/36k, would it be worth it just to cut my losses now or keep it? I would get a little under half back, (roughly $1300-$1400). I know the warranty only "covers" 2 years, since the first 3 is all MFG. So essentially I'm paying $1500 a year for 2 yrs for this thing. I haven't had any "major" issue, which I am mainly concern about the transmission or engine just needing a replacement/rebuild that would cost in the THOUSANDS, the other parts I can do on my own and I'm pretty mechanically inclined and do my own auto repair. If it were you, would you cancel it? Do I need to factor the % of risk into this truck? This is my first owning a domestic GM / Chevy. BTW, my truck only has 25,000 miles on her. Thanks in advance, Johnny

My truck is a 2018 Silverado, I've added towing mirrors with Phils custom cables and did the diode mod for the cargo light in reverse. I recently scheduled my truck for it's first oil change.I got to thinking, about mods and the effects on the factory warranty. Obviously I'm not going to remove the mirrors to take it in. but could easily pull the diode, Does any of this stuff void the warranty? Just curious what every one else's thoughts are on mods and warranty's?

Anyone else with a new 2014 Sierra having an issue with the frame rusting and paint/wax flaking off? I have 3000 kms and it looks horrible. I also own a 2011 Canyon service truck with 105kms and the frame looks like new. So irriating as my Sierra is a beautiful truck aside

I have a 2017 suburban bought about 18 months ago. I am looking to get the GMEPP plan added on to it. I remember reading that the price increased substantially after 2 years and either 20k or 24k miles. 2 questions: 1. Is it 20k or 24k miles that I should buy the plan before reaching? 2. Best places to buy it from?

John Goreham Contributing Writer, GM-Trucks.com 10-15-2018 General Motors issued a press release today that claims GM is "breaking new ground" with regard to new vehicle warranties. GM is planning to offer a 5-year, 60K warranty on its GMC and Chevrolet models and a 6-year 70K warranty on its Buick and Cadillac models. These new warranties will be offered at an additional cost to the new car buyer at the time of purchase. GM's standard factory bumper-to-bumper limited warranty on Chevrolet and GMC products is 3 years or 36,000 miles, whichever comes first and for Buicks and Cadillacs, it is 4 years or 50,000 miles, whichever comes first. Ken Mac, director of Chevrolet, Buick, GMC, Cadillac Protection, commented on this new extended warranty product, saying, "If you drive a Chevrolet, you know that any GM-brand dealer will take care of warranty repairs without paperwork, deductibles or exclusions. The same goes for Cadillac, GMC and Buick owners. Now, we’re offering people the opportunity to increase the duration of their bumper-to-bumper warranty far out into the future". The thing we find weird about GM claiming that this breaks new ground is that Hyundai and Kia presently both offer a warranty as long as the GMC and Chevy extended warranty at no added cost. Volkswagen goes even farther and offers a bumper to bumper warranty of six years and 72,000 miles at no added cost. This one's a head-scratcher for us in the newsroom.

I have a 2016 silverado that is under warranty. This morning I made a hard left turn and I heard a dragging sound under truck. My Mud flap came off. Is this covered under manufacturers warranty?

Is anyone swapping out wheels and tires to stock when they go for warranty work? I have a new truck and want to put bigger tires on but don't want to deal with all of the bs from the dealer for the next 3 years. My plan was to have stock rims and tires for when I head to the dealer for any warranty issues and put bigger tires on for normal use? Going from 265/65/18 stock to 275/70/18 Talked with the local dealer and yes i understand they would have to prove it in writing. Just wondering if it is even worth the time and money? Thoughts?

So, yesterday afternoon, I jump in my tuck after running errands. service notice flashes says "service 4wd" I dis miss this, check my 4wd knob and its in AWD, where it stays unless I need 4wd. I go to back up and turn and its clear Im in 4wd. Cannot get it out of 4wd. Tried running through 2wd/4hi/4lo etc. nothing no shifting at all. I drive a lot so my truck is at about 54K (its a 2015, bought in 2015) and I have had no issue with it so far. great truck. no complaints. So, I drive into town today, call the dealership (who at first said they couldn't look at it till Tues- wed) they eventually say they can squeeze me in today around 2. Great! I think this is great. Still under warranty, if it has to be messed up better now then in 6k more miles right!- but wait. looking up their warranty the most likely culprits (wiring, tccm etc) aren't covered under warranty. Really. with so many others having this problem?... I can accelerate and drive it, turns are irritating. Seeing that there aren't any real "fixes" for this since 2014 not a good start to this week. Anyone find anything that seems to have stopped this action from reoccurring?

Hi Everyone, So my truck has been at the dealership two times officially now. This 3rd time I had my friend look over it and he said the truck was within GM's specs. I don't know what GM's specs for vibration are but my vibration is in the mid 70mph range and excessively vibrates and then smooths out. This is a constant cycle throughout my commute. I am going to pull my driveshaft and take it to a shop that specializes in driveshafts. I know several people have had their driveshafts replaced under warranty and it did not correct the issue. My thoughts are if your truck originally came with an out of spec driveshaft chances are there is a whole stockroom somewhere in the Parts Department that has out of spec driveshafts mixed in with the ones without issue, hence the reason some people have no luck with driveshaft replacement. I really feel this could be one of the major issues behind all of this especially when there is documentation instructing the technicians at the dealerships to use hose clamps to balance the driveshaft. I'm sorry but I don't see hose clamps as a permanent correction to this issue. I will update this post when I get the results from the driveshaft inspection. Please feel free to share your thoughts and bounce ideas around. Collectively I believe we can find an aftermarket fix for this issue, it may not 100% resolve the issue but will at least save people from taking huge losses on trade in (if you did not go through a buyback/lemon/customer satisfaction program). (A lot of people are trading in / selling their trucks because of this issue) ***UPDATE 01-22-2016*** I contacted the Team at Precision Shaft Technologies (http://pstds.com/) in Clearwater FL and they were able to squeeze me in as a walk in. (Not there normal protocol. They were super friendly, informative, and VERY helpful!) I drove up there and pulled the driveshaft in their parking lot. They then put the driveshaft on a machine and it was a near perfect balance. They added one small shim to the U joint to get it perfect but I'm sad to say the vibration is still present and there was no change. However, when I returned home I put my truck up on jack stands and ran it up to the speed I had issues at (per GM's service docs) and there was NO vibration. I was extremely confused at this point. I dumbed it down and looked at the rear wheels while the truck was in drive (idle speed) on the jack stands (be sure to block your front wheels and disable traction control / StabiliTrak if you plan on doing this on your own). I noticed my left rear wheel has a slight flat spot it in so much so that it's extremely difficult to notice. I have not had a chance to swap a known acceptable wheel to the rear at this time. When I do I will update this post. A recap for a description of my vibration: -72-74 MPH there is a cyclic vibration. Roughly every 7-8 seconds the truck has a vibration and then the vibration disappears.

First post here but wanted everyone to know before they too get screwed by their power train warranty. I have A 2015 gmc 1500 Denali 6.2 and have had transmission problems after about 10000 miles or so . I have taken it in and asked to have the transmission looked at with nothing but “can’t find a problem “ from service. I installed a k and n dry synthetic intake to my truck after about 15,000 miles(I have about 50k now). Took my truck in about 7months ago due to the transmission hitting hard throughout gears. When i take the car out of park into reverse there is a hard knock and a decent jolt. Sometimes when driving it and getting onto a freeway the gas pedal does not work then kicks in after a few seconds (pretty scary ). Another issue is if I give it gas in 4th or 5th it revs high then I feel like I and being rear ended and then the truck moves. This is crazy that this is happening. The dealership did a reprogramming of the transmission and 7 months I take it back they pull it apart and find pieces of the clutch in the bottom of the transmission pan. They call me today and tell me that the aftermarket CAI is the cause of the problem. They say the mass air flow censor is covered in oil from the air filters oil? My air filter is a dry synthetic filter just wash with water and air dry so I call their bullshit. They then call me back and say they looked into the filter I own and it is a dry filter and there was no oil on it. Wow wtf. They bullshit their way out of everything. Just wanted people to know when they have this problem be one step ahead of them and keep your stock air intake . It is absolutely absurd to say my clutch is coming apart in my transmission because of a aftermarket air intake. They are also not honoring the warranty and want me to pay $4480 for a new trans. This will probably be my last gm car ever.

I've researched the net. I've read several threads on this forum. There doesn't seem to be a definitive answer. I'm getting ready to purchase a new '16 Sierra 1500 and want to add a 2.25 Inch Pro Comp Leveling Kit and 305/55R20 Fuel wheels on it. If I install the lift myself, will it void the warranty? Do I have to have certified mechanics install it to keep the warranty? Any GMC Dealers or warranty specialists on here? Thanks for the input.

I just wanted to share my recent experience. My '16 had the occasional hard shift at low speeds, and the occasional weird shift in traffic, but it wasn't terrible...the last month or so it seemed to get a little worse, but wasn't crazy. I had a few warranty issues I needed to take care of, so when I tool it in, I asked them about checking the transmission program and see if anything needed to be updated or whatnot. I get my truck back later that day, and I kid you not, it drives better than it was brand new (granted it only has 25k miles) but even just in traffic and around town and slow speeds...I didn't think I had it bad, but that reprogram did wonders! My point of this is, that many of you probably already did this...BUT...i have heard and read tons of threads about the 8 speed and people hating it...I would recommend taking it to the dealer whether you think you have a significant problem or not just to see if you are due for a program upgrade. Mine didn't cost anything due to warranty, but before they changed it, I think it had like $98 beside it...I assume if you took it in just for a trans reprogram that would be close to the charge (but I'm not 100% sure). Anyway, good luck if you have some weird issues, my experience has been very positive with the 'upgrade'!

Hey guys just bought a 2016 Silverado 1/2 ton and just have a few questions about the powertrain warranty and what will void it. Have about 8,000 miles on the truck installed cold air intake, exhaust and tires will be next. Want to level kit the front few inches but I am worried it will void the warranty. Any knowledge about this will be much appreciated

Taking my 2016 Silverado LTZ Z71 to the dealership this week. Any recommendation on issues to have them take a look at? I'm 6,000 miles away from hitting my 36,000 bumper-to-bumper warranty life.. thanks!

John Goreham Contributing Writer, GM-Trucks.com 5-12-2017 General Motors has agreed to increase the warranty on certain vehicles' headlights for up to 12 years of 150,000 miles. This after the government investigated owner complaints about low-beams suddenly shutting off on certain GM models. The headlight control module is the issue and Tuesday GM instructed dealers to begin honoring the warranty on about 300,000 vehicles now in circulation. The models affected include some of the following vehicles (not all): 2006 to 2009 Chevrolet Trailblazers and GMC Envoys -2006 Buick Rainier, GMC Envoy XL, Chevrolet Trailblazer EXT -2006 and 2008 Pontiac Grand Prix -2006 to 2008 Buick LaCrosse. This is reportedly a full recall, not a TSB, and owners will be contacted if they own a vehicle covered. The Detroit News speculates there may be more recalls coming as a result of this issue. NHTSA has not yet added this issue to its running tally of monthly recalls, so we suggest calling your dealer if you feel you may have a vehicle in the included group of vehicles and want to check if a fix is available.

John Goreham Contributing Writer, GM-Trucks.com 8-15-2016 Nissan announced this morning that for 2017, its Titan and Titan HD trucks will come with a 5-year, 100,000 mile BUMPER TO BUMPER warranty. We read the press release three times. This is not just a drivetrain warranty. Nissan is saying that for fully 5-years and 100K miles it will warranty its Titan and Titan HDs for all repairs. Nissan says that this makes it the company with the best truck warranty in America. This warranty also means that Nissan has just given customers and business owners that drive a Nissan pickup what amounts to a fixed cost of ownership for five years. At 79K miles the whole dash quits - free repair. Alternator at 99K miles - free repair. Headlights stop working at 72K - free repair. Wheel bearings at 66K - free repair. A Nissan truck owner will only pay for routine maintenance for 5 years or 100K miles. Clearly this warranty is most beneficial to owners who put a lot of miles on their truck. With most drivers putting 15K on a vehicle, and many business drivers up to 25K, the new Nissan warranty is ahead of the competition. To make the warranty perfectly clear, Nissan offered the following bullet points: - 5-year/100,000-mile bumper-to-bumper warranty beats competitors' standard protection programs by two years and 64,000 miles - Includes powertrain warranty – helping give Nissan full-size truck owners added trust and peace of mind - Covers all 2017 TITAN Endurance® V8 gas and 2017 TITAN XD Cummins® diesel and Endurance V8 gasoline-powered models - New limited warranty matches that of all models of Nissan Commercial Vehicles, including NV Cargo, NV Passenger and NV200

Will a programmer void a manufacturer warranty? If so, can you reset back to factory and would that be seen by the dealer? Thoughts anyone?

Does GM have any unpublished warranties on paint for 2003 trucks? I was cleaning the exterior windows tonight and noticed large areas of clear coat are missing / lifting off the top of the cab.

Hello all. I write this because I recently had my MyLink system stop working along with the speakers and light display on the steering wheel. This happens randomly one day. I was driving with the music on and the screen froze and the music stopped. When I reached my destination I turned the truck on and off and this time the screen worked no more. At night there is backlight illuminating the screen but the screen itself does not work. The only function it works in is the reverse camera. I was finally able to take it to the dealership and they are telling me the "resistors" (that's what they called them instead of diodes) is what caused the problem and now I am liable for the charges to get it fixed. Has anyone with this mod (low beam to fog lights) had any complications with their truck? Thank you very much for the responses. I own a 2014 Silverado LTZ

Has anyone had to claim anything warranty related to the power train while running a Black Bear tune? On my lists of things to do on my truck for this spring, is getting it tuned. I'm sick of how the transmission drives, and within the last month had to drive in a lot more traffic then normal. I just want to be confident that I can get at least 100k with the tune before something breaks.

I own a 2014 Chevy Silverado Double Cab 4x4 Z71 and wanted to share my experience as I approach 30K. When I first bought this truck it was great. I like the features, the ride, very smooth driving characteristics and overall design. Then the recalls started and so far I have had four performed that I know of. I also started noticing some issues that made me feel as if the 10K off MSRP I received was not enough of a discount. Below is recap and assessment of some issues I have seen in the last year and a half of ownership. 1. Paint- too thin and the appearance is blotchy, I am currently having some issues with adhesion as I watch the paint peel off the lower driver and passenger door, this will be covered under the warranty according to the body shop. 2. Recalls- mostly minor but I am sure as time goes on these recalls will increase in severity and inconvenience. GM should extend the bumper to bumper warranty, by a certain amount of time/milage, per recall. 3. Vibrations- there are several issues in this area. Tires are number one in my experience, then the v4 AFM mode and lastly the drivetrain are all sources for these vibrations. But if you look at the numbers on this site and do the math this seems to be an issue that only effects .5%-1% of trucks out there. Even with these statistics in some cases the vibrations have been eleminated. 4. Interior- nice to look at and touch but quality is a C+. Constant snap, crackle, pop, sounds heard mostly caused by thermo expansion and contraction. Then there are the rattles that are caused from cheap clips and loose components. One solution is to take everything apart and use dampening materials (carpet padding/expanding foam/electrical tape) to fill in void spaces and eleminate rattles. 5. Electrical- there are inconsistencies in the way the electronics perform. The radio sometimes emits a static/buzz sound through the speakers when I open the driver door. The bluetooth is temperamental, and the security locking feature sometimes has a delay. 6. Powertrain- GM has some work to do here. From the slip yolk clunk to the G80 rearend backlash knock, this area of the truck needs to be refined and shored up. There was also a leafspring knock that I had to deal with for awhile that I resolved by properly torquing the u-bolts. Even with all this I give this truck a "B-" grade. The 5.3 ecotec MGP along with HP/Torque numbers, the 100k powertrain warranty/36k three year bumper to bumper, and overall performance including towing/hauling make up for some of these issues. I would recommend this vehicle to others but if you are looking take your time and test drive this for a weekend and look for these issues. There are some that are better than others and this is the number one thing when looking at MSRP/resale value.

To start off with, i have been a GM guy almost my entire life. I had a 2013 Avalanche ltz, a 2011 Avalanche Ltz, a 2007 avalanche lt, 4 Chevrolet express vans, 2 Yukon xls, and countless other products over the years. Mostly they have been durable machines with very little problems. I recently bought a 2015 sierra 1500 Denali with a 6.2 and 8 speed with cash. It has been nothing but trouble with the transmission. The tranny clunked every time I stopped at a light and went to go again and in the mornings when I put it into drive or reverse it takes about 5 seconds and waits until it hits about 3000 rpm before the tranny engages. Countless trips to the dealer have led to a so called new transmission that works just as bad as the old one. And crappy base Chevrolet equinox rental cars. I mean like, I have a 65 thousand dollar truck, should I not at least get a rental with leather seats? GM is no longer returning phone calls and it is becoming a increasingly angering problem. I have about had it. if the truck was on lease I would drive it to the dealership and leave it there running with the keys in the ignition. but sadly I payed cash for the truck so until gm does something im stuck with a crapbox

Thoughts on the 5yr/100k mile warranty? I plan on keeping this vehicle long term -- this is my first GM vehicle, is it a good investment to purchase? The dealership I bought the car through (Hendrick) does not sale the factory extended warranty -- they sell their own... Is this typical?

I ordered my 2008 Silverado in August of 2007. Before it even left the lot I had my GM dealer install a GMPP Performance Exhaust System made by Borla. I have been pleased with this system for its entire life up until this past month. I heard a tingy-vibrating noise from underneath during certain resonant frequencies of the motor. Then it got to the point where when I slammed the door or went over a bump that the tingy sound became a rattle. I recently rolled under the truck to find that my stainless steel GMPP system had rusted though! I am very surprised by this, as I thought that Borla systems had a lifetime warranty. Is this something that GM should cover? I have this part on my original vehicle invoice but I am out of warranty on my truck. Any thoughts? Has anyone else had this issue? I have attached some pictures for reference. I should also note that it rusted through downstream of the muffler. Upstream of the muffler the clamp is cracked and looks like it's ready to break off any day now.
