Had to replace entire engine for same reason other GM engines are recalled for, the lifters and shifting cylinders. This should also be covered under a recall! It left me and my kids stranded.

POWER TRAIN
My husband was driving our 2018 Chevy Suburban when it suddenly stopped accelerating and he could no longer shift gears. Luckily, this happened while he was driving down a gravel road (approx 25-30mph). If he would have been driving at highway speeds, it is likely that he could have lost control of the vehicle. Our Suburban had no issues to this point and had always run well. We take it in for routine maintenance. We had it towed to a local repair shop, and they informed us that something had happened with the transmission and that it would need to be replaced. I have found several GM transmission recalls and our situation sounds similar to reference N252536750. Again we had no warning signs and had been experiencing no issues with our vehicle. If this had been something that we had been noticing problems and hadn't gotten it looked at, I can understand that maybe this had been something on going for a while that we had just missed maintenance on. However, for the transmission to stop so suddenly, I believe there must be some sort of larger failure in the transmission system.

ENGINE
On May 2, 2026, while the vehicle was in operation, the engine suddenly shut off without warning. At the time of failure, the instrument panel remained illuminated; however, the vehicle would not restart. In an effort to resolve the issue, the battery was replaced, but this did not correct the problem. The vehicle was then towed to a local Chevrolet dealership for further inspection and diagnosis. Following their assessment, I was informed by the dealership’s service department that the engine had seized and that metal debris was present in the engine oil, indicating significant internal engine failure. I was further advised that a replacement engine has been ordered. At no point prior to this incident were there any warning indicators, abnormal noises, or performance issues that would have suggested an impending engine failure. The sudden nature of this incident raises concerns regarding the cause of failure and whether it may be related to a defect or internal mechanical issue.

1. Sunroof 2. Driving on 81 N slightly past the Middlesex exit at highway speeds. My 4 minor children and I heard what sounded like a large balloon popping inside my car. Upon further inspection, my sunroof spontaneously exploded. Absolutely nothing hit our car. The more research I’m doing, this is a known issue with GM manufactures and they have done nothing to correct this issue. 3. I’m working on getting a repair scheduled, once we figure out if it’s under warranty or we have to pay for it through insurance. 4. No warnings

Today, 5/2/26 in Lewis Center, OH- My daughter and I were returning home from her Soccer game. The time was about 11am. We were in my brand new Chevy Z71 Suburban, with 4,100 miles. As we were slowing , approaching the roundabout, i noticed no power as i was preparing to enter the roundabout. I then see that the car powered off. It would not restart and i had no way to put into N. I had to call [XXX] to have the Sheriff direct traffic. I used Onstar, only to find out the tow was 216 min out. So the Sheriff called a tow and it was there in 30 min and towed to local Chevy dealership, thankfully before the closed for the weekend. I will find out Monday what the issue is- but it for sure seized up. So sad. I paid $100k for this truck. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The glass of the front movable sun roof shattered. The glass shattered while driving on hwy 89 in Wyoming with no traffic or no identifiable reason for the event. While some glass was saved most of it blew out when is shattered. The problem has not been reproduced or confirmed by the dealer. The dealer blames a flying rock or other object impacting the glass even though no vehicles or source of incident impact was perceived. No one was interested in taking a report. There was a build up of pressure inside the vehicle prior to the blow out of the glass which caused the drivers ear's to pop when the sun roof blew. The remaining glass was visibly pushed upwards away from the vehicle. A picture is available.

POWER TRAIN
The transmission of the 2021 Suburban failed. While operating the vehicle down a state highway, out of nowhere the power was reduced significantly while in traffic. It would not go over 30 MPH after forcing itself to 30 MPH while driving down the busy highway. After struggling to find a safe place to park, the vehicle would not, and still will not, go into reverse. There were no warning lights of any sort prior to this incident. Now there are several warning lights. The vehicle has been towed and taken to a repair shop with current unknown diagnostics as we are waiting our turn for the vehicle to be diagnosed. This vehicle has a transmission that is currently under Class Action for GM knowingly selling defective transmissions.

While driving down the high way with the check engine light on, a message appeared on the screen and said “unable to shift soon. Service transmission immediately.” After driving a few more miles the vehicle shifted to neutral, and then as soon as I got on the shoulder of the highway and slowed to approximately 5 mph, the vehicles wheels locked up and the car jerked aggressively into park. This exact issue has occurred multiple times while driving. It is unsafe to drive the vehicle.

While driving on interstate XXX on 4/17/2026 my vehicle lost power I had to pull over on the shoulder thankfully I was able to do so. Restarted the vehicle for just a short bit and it said loss of engine oil pressure and died. would not restart. Ultimately had to be towed to a GM dealership Lynch Chevrolet in [XXX] . Was told the engine was shot and was covered under the safety recall. There was a recall on the motor I had brought it in to get rectified sept 2025.a heavier weight oil was added and filler cap replaced with 40 weight oil identification. . I just had an oil change the day before the incident on 4/16. What is concerning I'm worried about the long wait plus plus online blogs that indicate the engine failed numerous times even after replacement. I was told from the dealership that the engine was on back order and they cannot give me a time on when it's going to be available. But again I'm worried about this vehicle in general in moving forward or trying to anyway. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
