Hi, my name is [XXX]. I have two major issues with my 2021 Chevrolet Suburban: The value body failed for the 2021 Suburban in December, causing engine power reduction and the engine transmission was not shifting properly. This was covered by my extended warranty, which I paid $2500 extra for at the time of purchase. Also, this VIN is for a Chevy Suburban Duramax Diesel. The Emissions Control Module ( ECM ) light has come on several times, starting from about 20K miles to now 61K miles. I noticed the ECM light comes on at about a 8K mile interval. I take it into the dealership and they have told me this is due to a software issue and then they reset the light. This has happened on at least 4 occasions since about 20K miles. However, now at 61K miles, they are telling me that the exhaust system has a leak and it may not be a covered repair under even my extended warranty. Basically, General Motors has kicked the can down the road on the ECM issue until it is no longer under warranty, and now they want me to pay for this expensive repair. This is wrong, I hope you can protect me and other Duramax owners from GM's unscrupulous business practices. You can reach me at [XXX] for more details. Thank you, I am considering legal action against GM for this issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Has been in the dealer multiple times for very hard shifting issues. Jerks when shifting gears from stop or in lower speeds. They have tried everything and cannot figure it out. But the techs have felt it when driving as well. It has been doing it for a long time. And it-??s a concern when driving, I do not feel safe.
Originally we had an engine light come on upon the engine chugging and the vehicle lunging forward at times. The diagnostic showed a bad lifter on the passenger side. They then replaced the passenger side lifters. We asked them to replace both sides since this was a known problem with our year, make, and model. They said they weren't replacing both sides of the lifters. Luckily we were still under the warranty for this repair. Now, a little over a year later on the day we were taking it to trade in, the engine light came on and the engine started chugging again. I knew immediately what the problem was. I took it to the same dealership and they quickly diagnosed it with a lifter failure on the driver side. Unfortunately we are out of warranty at 80,200 miles. The vehicle is only 2 years old. We have been advised not to drive the vehicle until it is repaired. I should not be responsible for the cost of the repair when this is obviously a known defect with the lifters for my year, make, and model. They should have replaced all lifters when the vehicle was originally brought in for the passenger side lifter failure. This should already be a recall by GM for the amount of vehicles that have and will experience this lifter failure. There is actually a class action lawsuit filed against GM for the lifter failure.
Multiple issues with transmission since owned. It randomly goes into "limp" mode and everything will blink and it won't start back. The transmission has always shifted hard and sounded funny they told me if was normal for the vehicle. Leaking transmission fluid when owned for 4 months. I have had to the dealer multiple times, several repairs, told it is safe to keep driving by GM. The inverter is bad and told me it was ok to drive until they can repair. GM will not give me a fair response or answer. The dealership won't buyback, and offered to purchase for nearly 30k less than I bought it for 18 months ago brand new. The engine light comes on and off randomly told me it was ok with a diesel it may do that when it gets cold.

Came to a stoplight and the car came to a stop. The car then automatically shifted into park on its own. The car would not shift out of park an the engine would not start. The car just died. Police showed up as I was in the middle of traffic and no one could even get the car to shift into neutral to push it out of the road. Very dangerous situation. Tow truck came and they could not even get the car in neutral. So they had to drag the car onto a flat bed. Dealer has examined the car. The starter was bad, the fuse box was bad but the major issue was in the engine where the lifters went out. To have the lifters go out at less than miles is unacceptable. The dealer commented that they are seeing this issue constantly from 2021 Chevy SUVs. This is a major safety issue in that there is no was to put my 2021 suburban in neutral when this happens to clear the vehicle from a busy highway. Please investigate this.
The lifter rods failed on my vehicle that has approximately 8,000 miles on it. The dealer said that this is a known issue and that there is a service bulletin out for it.
Drove up to a stoplight 4th car in a turn lane, came to complete stop. Some cars closed ranks a little further so i released my foot off the brake and moved up a few more feet and stopped again. The car then accelerated with brake fully depressed and wouldn't stop. I then put gear to neutral Tac was very high maybe 5000. Put car into park and then turned off the engine. Restarted car and continued on my way. Contacted Chevrolet and my dealership for a service diagnosis coming up July19,2021. No image to anyone but I have heard of this problem before a malfunction of electronics controlling the drivetrain. Can something be done before any injury or death occurs.
