2021 Chevrolet Suburban other reported problems

UNKNOWN OR OTHER

COMPONENT: The 10-speed automatic transmission failed on 6/29/26, locking the vehicle completely in neutral. The neutral override could not be disengaged even by dealership technicians. Vehicle is currently at [XXX] Chevrolet, [XXX] and is available for inspection. SAFETY RISK: I have 3 young children who are regular passengers. The failure occurred without warning. Had it happened at highway speed in oncoming traffic, I would have had no ability to move the car — creating a direct risk of a serious or fatal collision. CONFIRMED BY DEALER: Yes. Don Hewlett Chevrolet received the vehicle on 6/30/26 and confirmed the failure is directly related to two active federal recalls: NHTSA #24V-797 (10-speed transmission valve body failure/wheel lockup) and NHTSA #22V-036 (driveshaft assembly/loss of propulsion). Vehicle has been unrepaired for 13 days with no timeline provided. OTHER INSPECTIONS: Vehicle has been in possession of Don Hewlett Chevrolet since 6/30/26. No manufacturer representative, police, or insurance inspection has occurred. WARNING SIGNS: None. No warning lamps, messages, or symptoms appeared before the failure. The power train locked suddenly and completely without any prior indication on 6/29/26. Despite the dealer confirming this is recall-related, they have indicated I may owe partial repair costs. Under 49 U.S.C. § 30120, GM must remedy recalls at no charge regardless of mileage or warranty. I am requesting NHTSA investigate both the failure and GM's attempt to charge the owner for federally mandated recall repairs.

The check engine and traction control light came on in my car. This was accompanied by a clanking sound, shaking. The panel said “ SERVICE ESC” “ service traction control” and “ forward collision system unavailable” The Chevrolet light logo on the back of my car will also not turn off occasionally whenever the car is turned off.

My vehicle is having an oil consumption problem. 2 quarts were missing from my oils consumption test. The dealer is now doing a secondary oil consumption test and I’ve read up and learned that there have been a lot of recalls with the engine and oils changes.

I was driving and then the vehicle started running rough. There was no indication or warning lights before this happened. This is a huge safety issue because I could have had a wreck and injured people and my very own family. I took it to a Chevy dealership. They inspected the suburban and number 4 cylinder had a pool of oil in it. And they told me it need a new engine. Which it has the L87 engine that all the GM recalls are on. However, they are telling me mine isn't on the recall. They don't know if GM is going to cover it because it has 111,000 miles and it's out of the power train. It's the same engine they're having trouble with engines failures on. And I believe mine should be under the recall.

There is an issue with the transmission when i accelerate at a slow pace. The car shakes and vibrates. Theres a possibility of an issue with the transfer case 4x4. When i turn the steering wheel and drive, it feels like it locks. It feels like 4x4 is on and theres a odd sound as well. I took my car to Hamilton Chevrolet and paid for inspection. They told me that there was no issue, but the issues i mentioned earlier in this message was mentioned to them. Those issues are still occurring. This is a recall issue but when i put my VIN number in, my car shows that there is no recall on it. There was many people who mentioned this problem.

I was sold a vehicle from a dealership in Green Bay Wisconsin under the impression all safety regulations were met. The day I drove it off the lot, I had issues with the back drivers' door, making wind noise. I had messaged the salesman, he stated it may have been the door seal. Days went by, it wasn't sitting well with me, I made an appointment with a local body shop in. regard's to the door and suspicion of something not right. I brought it to the body shop, they informed me, that the back air bags were deployed and stuffed back into the roof, body work on the left side was done incorrectly and is very unsafe to drive, seat belts where my children sit were finger tightened, frame is held on by a bolt etc. The body shop states that if this vehicle were to be in an accident, it would not sustain impact the way vehicles are designed to do so. The owner of the dealership I had bought from refuses to come to an agreement about this situation. I have all the paperwork and documents from the body shop along with another local dealership near me who I also brought it to look it over as well so the owner could understand that this vehicle should have never been able to be sold on his lot. They also agree that this is super unsafe and should not be driven until it is fixed properly and all safety standards should be met. They believe that it should have been totaled out, it is very obvious that the left side was hit and smashed in. I also asked the owner if he would feel safe for his children to drive in this vehicle and he said, “no” I have many documents/pictures/reports to share once needed.

Seat, mirror, steering column pre-set driver adjustments do not come into proper driving configuration on a regular basis when starting vehicle. This is a dangerous situation when a malfunction does occur. Seat has tendency to squeeze driver torso into steering column and knees into dash. LH mirror inadvertently and unexpectedly tilts down toward the ground and ofter unnoticed. This makes for a dangerous condition where the driver assumes that there is no oncoming rear traffic and it's safe to pull away from a curb from a stopped position. This condition has occurred for over a year and while the vehicle was covered under factory warranty. Numerous trips to Bonner Chevrolet in Kingston service department for remedy have yielded nothing. Bonner Chevrolet walked away from this serious issue and told us there's nothing more they can do and said, sorry. In contact with Chevrolet through Chat messaging, the recommend other surrounding dealers. None are interested at this point. the chat messaging is as useless as Bonner Chevrolet. Meanwhile I'm driving and paying for a useless and dangerous vehicle which no one knows how to repair. This has been an ongoing event since June, 2023.

"SERVICE SAFETY RESTRAINT SYSTEM" message will often and randomly display, stay illuminated for random lengths of time, and then clear. Dealer Service centers are not taking the random/intermittent fault of the Safety Restraint System seriously. Passengers are at risk (unknow severity, assume the worst) due to a Faulty Safety Restraint System.

Purchased the new 2021 Chevrolet Suburban, 4 miles on odometer and left the dealer. Less than 20 minutes from dealer AC stopped working. Called dealer thinking it was small error. While on phone I looked under the vehicle which was now emitting foul burning odors. Noticed a very large amount of oil(1quart+) dripping from everywhere from engine to exhaust mid way down vehicle,oil cooler line was blown off. Towed newvehicle to dealer. Chevrolet wants me to keep this vehicle even though there was a TSB issued last year about this same issue. Chevrolet was supposed to fix before shipping vehicle and demanded dealers to do the same but did not follow its own advice. Now they want me the consumer to take a vehicle that now has 17 miles on it that has been repaired even though the issue was supposed to be remedied by manufacturer. GM/Chevrolet considers this a new vehicle even after major service for a known issue and wants me to marry this vehicle for 6 years of payments. I put down $22500 cash and this is the slap I get as consumer!
