I think that's what the majority of people settle for and don't go through the whole process.

legally with a buyback its GM doing it voluntarily so they can decide what they want to do. if you wanted out, they could make it take longer and force you to go through lemon law and risk losing outright. they offer the buyback and replacement, and generally thats that.

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

It's my observation that the more one reads this thread the more ones truck vibrates and shakes.. Personally, I think the administrator should pull this thread as it has long ago ceased to provide any constructive new information. It's become one of those circular discussions - verbal masturbation is the term I believe....

I'm leaving it up so new owners or people shopping for a new truck can be made aware that there is a CHANCE a truck could vibrate or shake, I know I prefer as much possible info on an item before a big purchase

Those of us with MULTIPLE vibrators come here hoping that someone out there one day comes up with a fix. A cure for cancer will happen before a fix for these trucks happens.

I have a 2015 Silverado V6-----It`s not the tires, rims, pinion angle, drive shaft, rear end, front end, shocks, etc...... It`s in the power train, period! Open your hood, (took me awhile to finally look under the hood too) with your truck in park, motor running. You can see the whole motor, trans, vibrates! I videoed it, and its bad. When it started vibrating while at a stop light, that's when I decided to open the hood. One person on here I think nailed the problem, Brandon1282/ After completing all tests found that TCM could not be 'pulse-width' tested, only command on or off. With these measurements we determined that the TCM was sending an erratic signal causing the torque converter to be commanded erratically. This caused potential damage to torque converter. Therefore, I replaced the TCM (Signal) and torque converter (damaged internally). Road tested vehicle; now operating to GM specifications with no vibration when tested under the original conditions.

​​

​​I knew it wasn't tires or rims when it first started a week after I bought it. Tach is not steady, same vibration, but harder when it down shifts when slowing down.

No power train should be vibrating like this, especially in park at idle. No way to post the video on here, or I would.

 

Already gave GM there last chance to own up to the problem, tech said everything all the others said on here, it`s up to specs. the dishonesty is apparent from GM tech, the dealer techs, the owner of the dealership, and of course the all trust worthy salesperson. Not!

The first test drive the head service tech admitted it was the power train on the test drive, and pointed out it was the torque converter. also said the transmission is to big for this engine, and that the V8`s don`t vibrate as bad. Wow! But when you get them back to the dealership, mums the word. They blamed it on the tires. second time they kept it for 15 days, even put a new rim on, and tire. The loaner was exactly like mine, except it was a 2016 with a 5.3 V8. It vibrated too with the same whining sound from the trans area. Third time road with a tech who claimed he fixed it by road force balancing the tires, no it`s not the tires I told him, and he explained on the ride along with me that mine was one that didn't have it as bad as others he has ridden in. But back at the dealership, it`s up to specs and there is nothing more they can do. Amazing! Oh and the loaner they had for me the third time, was a $50.000 crew cab 2016 5.3 V8. Same vibration in it as well. sad!

 

Luckily our lemon law here is pretty strict and supports the consumer, final demand replace and/or refund letter is coming your way GM

Have been buying GM vehicles all my life, have 3 now. 1972 Custom 10 Reg Cab long box, 2011 Equinox, 2015 Silverado reg cab long box, I call the vibrator! Our 72 C-10 which has been in the family since 1974, makes the new truck seam like a fictional GM product.

 

Disgusting dishonesty being displayed by GM, and it`s dealerships!

 

P.S. They first claimed that it`s a characteristic of all the trucks, lol! That needs to be on the window sticker then, because I`m not going to purchase a brand new truck that vibrates!

The whining noise is not coming from the trans, it is coming from the new 2 stage vane style oil pump on the engine. The pumps make a whining noise that carries down the pickup tube to the bottom of the oil pan making it sound like its the trans when listening under the truck.

So, if hey were to pull the whole thread, would anyone be aware of the Chevy Shake? I can only assume you do not have a vibrator?

For those of you trading your vibrating trucks in, why not go through the buy back process and not lose thousands during a trade?

Perhaps because they no longer want to deal with GM anymore with all the hoops people have to take. Just dump it, take the loss and carry on with another manufacturer. If I had the cash and was not buried in my truck, I would take this route as well. Who wants to deal with the hassle?

Most BuyBacks have to stay with a new GM

I don't agree. If you are firm and want a cash buy back you can get it. Worst case tell them that you are going to open a BBB Auto Line complaint and then you have the option in arbitration. Maybe not true in all states but most. Check your state Lemon Law. I was offered a replacement (GM Speak), refused and got a cash offer. Refused the cash offer and opted for a replacement but a 2016 vs the 2015 originally offered. I was close to model change over so got my 2016.

No, has nothing to do with listening under the truck, this whining noise is while driving down the road and foot off the accelerator, or at steady speeds. And can be heard from inside the cab. I don`t need anything explained to me. As far as I`m concerned, any attempted to differ from the facts I`ve stated, Just gives more reason for GM to ignore it`s consumers!

I can hear mine from in the cab while driving also if the radio is off, if you take a stethoscope to the trans you will find that the noise is not in the trans and then take the scope and listen on the oil pan and follow it to the timing cover it will get louder. I have already did this because I had the same concern you do with the noise. So yes maybe you do need stuff explained to you unless you are the all mighty know it all.

Nobody wants to deal with the hassle, but I'll be damned if I'm taking a loss on my truck. Per FL Lemon Law my truck qualifies not only by the 30 cumulative days, but also the 4th and final repair letter was sent and is now complete. It has taken a while, but if GM does not offer to repurchase I will go through BBB Arbitration and I'm almost certain per FL law GM will have to repurchase my truck. The consumer has the right to chose repurchase or replacement (at least in FL).

GM response, not a safety problem, no recall - yeah but your product has a serious defect. it vibrates and shakes. For them to say that it is not safety related by default tells me they know the root cause. If the vibration was due to ball joints / tie rods / hubs and studs, those are safety related. They know, they won't tell, they won't fix ... someone has done the risk / profit / fix calucation and the customer has come up a loser. All we need is Goodyear, Firestone, Michelin, and Firestone to give GM the middle finger and say "Our tires are fine, fix your truck". Think how much money those poor suckers are losing with multiple tire swaps back and forth. There has to be some negative publicity that GM dealers are pushing to the tire dealers... "oh no, the tire has a road force number of 30, it sucks, these (name manufacturer) tires suck"... Road Force of 30 works on every other vehicle just not a 2014 Silverado

I have the slight shake in the cup holder area of my console. I do not feel the vibration in the steering wheel, headrests, dash, etc. It isn't too bad, sort of annoying when the little cap ring on the water bottle starts rattling, but I really do not notice the vibration any more than that. Mine has this same vibration at all speeds over 20 mph and therefore does not seem to be related to vehicle speed. Today I decided to test the water bottle in other areas of the truck. I set it on the transmission tunnel right in front of the console/middle seat and low and behold the water in the bottle was steady. Anyone else try this and were your results the same?

Well, I picked up my truck today from the GM dealer after they put on new tires, and balanced the wheels. Guess what? No more shake! Now I have only put 35 highway miles on the truck on the way home from the dealer. Those 35 miles were vibration free. I am curious to see how this fix hold up as I put more miles on the truck. At least for now I can drive it on the highway.

      2012 Sierra 1500 AC issues

      By Fishbones · Posted

      I just started having AC issues with my 2012 Sierra. The symptom is blowing warm air on all vents.  Here is what I have checked so far. Compressor clutch appears to be engaging and cycling  I checked all fuses and relay, no issues. The only thing I have notices is the short line that comes from the firewall is very cold / frosted. This line is approximately 12 inches long. The coldness stops when it hits the first line connector. As far as AC compressor - At first start the clutch engages, runs continually, Short AC line frosts up. After idling for several minutes the AC line thaws out some but is still cool and the compressor clutch starts cycling on and off every 5 seconds.  Any suggestions on what to look at next would be appreciated.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Unless you are using a bypass filer system with a Beta of 1000 at 2 micron the commercial filters we have access to, even the very best of them, are poor at the 5 to 10 micron range the typical UOA test can 'see'. Point is there are some truly awful filters being sold A 45 micron Beta 75 filter is what Dyson used to call a screen door on a submarine. That leaves wear metals disconnected from filtration unless particulates are larger than the test can 'see' and yet captured by the filter...which is its job. If that is true then you have a major issue screaming at you.    The graph isn't mine. It belongs to GM and their study on this area. I looked up those studies and provided those SAE tech paper addresses multiple times. Machinery Lubrication displayed it and confirmed it. So if you have doubts about the study you'll have to take it up with GM Engineering. Just like you would have to take up a difference in opinion about the meaning a word with Webster or the length of on inch with the National Institute of Standards and Technology.      Most manuals have two schedules. "Normal Service" and "Severe Service". On it's face it tells you that oil in severe service is more highly stressed and doesn't "Last as Long". The item to bore in on is LAST...what does that mean?    It's the same question one asks about how long to toast bread. What are the inputs? Bread type? Wattage of the toaster? Distance from the elements? What is your preferred level of done?    So lets paint this with a broader brush. Oil is made up of the base and the additive package. The first is altered by heat and oxygen and later is sacrificial with a finite life subject to inputs toward that end. Resistance and supply.    It is the reason an OEM's OCI's are determined by 1.) the specifications of the recommended lubricant and 2.) risk management toward the bottom line. Those lubricants are also subject to cost effectiveness for the OEM.    There is a tendency for most people to believe that the OEM recommended oil rest on the top shelf and that anything other is lesser than. Truth is there are more oils on higher shelves than those on the lower shelf below the OEM's. They make that choice on COST TO THE OEM. Testing is incidental to the margin.    GM makes MONEY, the car/truck is a TOOL to leverage MONEY. Insert whatever car brand you like. Until you forking over a million plus COST not quality is the driver. Thus it is by DESIGN the recommended OCI's and oils fall well short of 'best practice protections'. Proof isn't hard to find. GM Ecotec I-4 2400 breather system and cold start PCM tuning has killed more motors and resulted in more litigation for those that used the 'recommended' practice than GM could bear. What was their response? SHORTEN THE OCI. TWICE.    I don't know how long to leave oil in an I don't know how the oil will respond to MY circumstances and because I don't and can't blanket statement or anecdotal evidence my way out of it.....I TEST and FIND the right OCI for the oil I CHOOSE. There is no shortcut but there is blind allegiance. I don't blindly trust anything.    People hear the word 'detergent' and believe that in the context of oil it means the same thing as laundry soap... Only in the most rudimentary way. It's the first additive to give up on you and they are putting less and less with each new API standard. Solvency can be used but it cost. Some unique undisclosed chemistries can be used. Valvoline R & P in example. OEM's haven't an interest in anything they see as limiting market participation. Whatever.

      By KARNUT · Posted

      For some unexplained reason my father wanted a salvage yard. As we were getting the family business off the ground one brother ran the salvage yard. We gathered there when rained out working on pipelines in the eighties to pull parts. Perfectly good running vehicles would come to us simply because they wouldn’t pass emissions inspection. We were able to swap parts and sell some of them. I got a clean old nova with a bad engine. I pulled a perfectly good small block out a Camaro. A father and son project with a rebuilt engine. The son couldn’t get the engine running right. The problem was the spark plugs weren’t gapped. The 90s vehicles probably widened the gap of shade tree do it yourself engine repair. My do it yourself hot rod repair stopped at the 70s. After that my trusted mechanic kept them in running shape.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I have an old dental chair in my shop. Something I got for free and apparently it has more than scrap value? People collect them although mine isn't restored or anything. It's visually interesting (1930's Ritter) which is why I like it. And it IS decently comfortable if you kick back.   When a good buddy of mine saw it he said, let me guess, Atlas. It's a conversation piece? As in, you ask the questions, they do the talking?   Where do you hide the jar of teeth?   I would never.

      Are we talking about the same thing, though? The 7 versus 3 wear metals was from Lakespeed's 3.0-specific oil brand comparison test between AcDelco oil and Mobil ESP. The filter remains a constant so whatever excess particles the AcDelco oil is producing aren't being filtered out.   I'm assuming there's a parallel comparison to be made; IF the filter can filter down those particles, engine life increases, and your graph makes the case that a better filter (lower micron rating) can increase engine life. Introducing fewer particles AND filtering those particles with higher efficiency is the best of all worlds. Good oil, good filter.   Where we may disagree is the "baseline relative engine life". I'm more apt to believe the base engine life value is 200k+ on very average oil and filters, "bulk oil of unknown brand and white-label generic fleet-grade filter, Jiffy Lube"   Going from a 10 micron filter to a 5 micron filter should boost a base 200k to 275k in a vacuum as a single factor alone.   Here's the whatabout: How does regularly changing the oil and filter ahead of recommended schedule influence baseline engine life? Most people aren't going to science the heck out of this stuff or ask about Micron ratings, HTHS, or wear comparison tests at Jiffy Lube. Most of the Jiffy lube techs would say they need to call their tech support line to even try to get an answer.   --   Because we love anecdotes here, when I was fishing for 4.3 parts at a local yard this weekend, ALL of the 4.3 vehicles had well over 200k. I love looking at odometers of junked vehicles. How far did THIS go before landing at the crusher? The ones that still had engines weren't seized. None of them were vehicles I'd consider were Amsoil queens, in fact most of them had some kind of service cling-sticker in the corner of the windshield indicating it probably had very average maintenance services. Even the fresh parts rigs- I'm not sure taking an S/T series to 400k has much value considering the running value of those vehicles was probably somewhere around $1,000. 25+ years is a good run on time alone.   The intake manifold I salvaged had clean and bright pool areas. As expected, I found the fuel lines in the manifold rubbed through, just like mine. I'm guessing the lines on that donor truck started leaking, the truck started running rough, and its owner said that's enough I'm unwilling or can't take it out of service for several days, or spend $1000+ to repair it at a shop, it's simply time for a newer more reliable vehicle (or, more than likely, this is the 2nd, 3rd time this has happened in the truck's lifetime). While I don't count on my Blazer for reliability, the thought of giving it away for parts at certain points during my adventure, and being mentally free from its needs has has crossed my mind. I'd be losing $1500 or so, but I can only make more money; not time.
