@DaleJr @chevrolet Hey @GM WTH! I’m a disabled veteran and my 2021 Sierra 43k miles (6 months out of powertrain warranty) transmission is blowing up and your dealers told me to pound sand. How about a little help. I don’t need a new truck, just this one fixed. Money is tight…help a guy out.

I was driving my 2017 Traverse today and the transmission took a 💩. Had call a tow truck.

Buyers beware! On the road with our granddaughters hoping to enjoy crew days of RV camping, our 2019 Yukon’s 6-spd transmission suffered a catastrophic failure leaving us stranded hundreds of miles from home and left with a very expensive repair. @GMC

@GMC paid $75k for top of the line truck and it blows apart rolling down the interstate. Product is cheap.

Me too bro. The worst is when they broke down a deer happened to jump across the highway and people swerving looked like they were coming for the truck that was broke down on a shoulder of a highway not a lane to pull off on or a shoulder wide enough to fit a truck. Then the sister who came to help (also just in a bad accident) was so scared she almost jumped over my 1 year old to protect him. This whole experience has made me lose complete faith in this brand. After this is sorted I’m selling it and buying something else 💯

Hey @GMC So the transmission went again! After a couple months when they put the new transmission in at the local gmc/chev shop it hesitated and we notified them to which they said they couldn’t get it to do it. We then took it for a second opinion, they suggested it wasn’t seated correctly, we returned to the gmc/chev and they said “no it has to be broken in” which is a lie. Fast forward two years and the transmission started slipping the same way it did in 2024 before it fully broke. We have a video, sent it to them, they wanted us to bring it in so they could hear it, they had it 20 hours or more and came back and said “nothing wrong, can’t get it to do it” (at this point it slipped like 20 times per day so how they couldn’t get it to happen is beyond me) so we got a much better video and planned to drop the truck off and the video this morning. Unfortunately it broke down on the highway last night with our 4 children with. We had it towed to the gmc/chev shop and then when my wife went in this morning the Shelby lady at the front desk was rude and talking over my wife and when my wife said not sure if we want them to do the transmission work itself she threw the keys back at my wife and said “then it’s your problem” my wife reminded them that the transmission is under warranty and was told someone will look at it and she left. She came home upset so I called. I curse (listen to any of my 400 live recorded spaces) and I was upset, after trying to talk to this Shelby lady it was clear she didn’t want to hear what I had to say and talked over me, further frustrating me to which I said “I expect a prompt response as to what is going on as I need a rental because 3 of my kids are in school right now and need to be picked up” and hung up. Alex the sales manager called me back almost instantly not about the transmission but because I was “aggressive” to the staff and they have denied serivce. I was not threatening at all. I cursed and I’m frustrated. While I am writing this, my wife who was not part of this call was sent this Absolutely trash service since day 1 from these people I wouldn’t let them put a chain on my bicycle at this point but they should be paying the tow bill, not me! This issue has been apparent after 4 months of them putting the other transmission in back in 2024 and the tow bill we covered was for $145 and that’s about all I’m spending or it can rot on their property 💯

Next week, Im most likely getting a new car. My @GMC Terrain has officially run its course… brake lights turning on by themselves, @SiriusXM not working—thing’s basically haunted at this point. Upgrading to a @Chevrolet Trailblazer. Time for something reliable. #Upgrading

@Jay_Mac_333 @GM Our team would like the opportunity to look into this matter on our end. To do so, please email details revolving this experience. Thank you and we hope to hear from you soon.

@GMC and @GM have totally screwed me! After their faulty motor almost killed my son and I they said they would help. We'll their help has done nothing but cost me money and days off work. The email address they gave me is a proxy and not even an actual @GM employee!

Fewer than 85k mi on my @GMC Terrain and the motor is shot due to issues they knew about and didn't tell me. Dealership says I'm outta luck. Owe thousands on it and it will cost thousands to fix! Worst is, my toddler was in the car and we almost lost our lives behind this defect.

@GMC My 2026 Yukon Ultimate Diesel has been at the dealership since February 9 waiting on parts for a module failure resulting in a catastrophic transmission failure. Customer service offers no repair timeline. Waiting impatiently.

The First Ever #GMCSierraEV #Denali. Meet the Denali of EVs, towering above your expectations of an electric truck. See it 10.20.22 @ 5PM ET on s.gmc.com/gfgaj5

@sabby2707 We appreciate you providing more details to our team, Sabby. We will be sure to follow up with you in your email.

@GMC Still no concrete action from @GMC or its dealership as I am still stranded with an expensive piece of metal that can not be driven .. #HummerEvSUV emails being exchanged with GMC social media team but, still no appointment from its dealership to fix the issues

@GMC Vehicles’ side mirrors and windows are not functioning, creating hazardous driving conditions. I informed a GMC representative over the OnStar call. GMC must take immediate action to resolve this issue. #HummerEVSUV2026

My @GMC #terrain has 37K miles on it (super low for a 2018) and has been in the shop 4 times for catastrophic electrical and mechanical system failures, none of which has been under warranty. Just proof buying American means buying junk.

Disappointed doesn’t begin to cover it. My 2021 GMC Yukon was diagnosed with a disconnected sunroof drain tube (no prior work ever done), a leaking sunroof frame, and mold under the carpet as a result. I am a disabled veteran. Despite documented findings, @GMC, @CarMax, MaxCare (serviced by CNA National), and @AlfredMatthews have all declined to help — with the dealership refusing to even submit a goodwill request because I didn’t purchase the vehicle there. Health & safety shouldn’t depend on where a car was bought or which warranty loophole is used.

@GM issued a recall on my 6.2 engine for potential issues that may result in a lack of propulsion. I scheduled an appointment with my @GMC dealer, and was told the vehicle “passed inspection” after it was tested for the issue. The vehicle had 148K miles on it at the time. (1/2)
