2025 Chevrolet Suburban 1500

We have 8,625 miles on our 2025 Suburban. We were going down the highway when began to hear a unfamiliar noise. We pulled over into an error to inspect and didn't notice anything under the vehicle, which we thought might have cause the noise. We put into drive and went less than an 1/8 of a mile and our suburban lost acceleration and stopped. It would not start and couldn't not be moved, until roadside assistance took it to a Chevrolet dealership. The dealer stated the engine seized up and needs to be replaced. We were fortunate we were not going any more than 20 miles per hour and were not on a major highway.

My rear passenger door flys open while driving. It happens during very cold weather. It also will not latch when trying to shut it after getting off the road and trying to shut it. My daughter has been in the seat next to the door each time and it has happened multiple times. Betten Chevrolet has tried to fix it twice and it is currently in their shop. This is totally unsafe!

The engine self-destructed due to a thrust bearing failure as described in General Motors Technical Service Bulletin 25-NA-307 There were no warning lights prior to the engine failure. The vehicle has been inspected by Carl Black GMC in Roswell, GA and been found to fall under the Thrust Bearing Failure TSB According to the service technician, these engines have been failing in large numbers.

Was driving on highway and engine started to make a noise, performance and power were impacted, the engine service light appeared. Exited highway on near offramp, when on offramp vehicle engine stopped working. Vehicle is a 2025 Chevrolet Suburban with 6.2L engine. Dealer has stated engine is seized. Seems exactly like the current 6.2L engine recall for 2021-2024 model years that results in engine failure. Vehicle is 7-8 months old, and only has roughly 12,000 miles.

Engine failed going 70mph on highway at 2k miles. Display said acceleration no longer available and app said transmission code was needing to be checked however once taking to dealer I was told it was an oil sensor then told there was shredded metal in my engine and I needed a full engine replacement. My car was in the dealership for over 50 days. I was pregnant and with two small children in the car when engine failed at high speeds. After my car was returned to me the engine overheated and failed again. The dealer claimed GM sent them an engine with cut hoses. I was 9 months pregnant when this occurred also on the highway going 65mph. GM refused to buy back the vehicle 3 times.

The complete infoentertainment system went out within one week of purchase and has been in the dealership possession since. The dealer’s service department tried to perform updates on the system after the radio went out and it caused the whole dash to go completely black and they haven’t been able to get it to turn back on. The vehicle has been in the shop for 8 weeks now and no estimate when I’ll receive the vehicle back. Since the dash is black you can not see the speedometer, gas gauges, etc and it is not safe to drive without it having fully working electronic components. The dealer is next going to try and replace the radio but that part is back order indefinitely.

7/13/25: Car repeatedly jerking/shuddering/rough ride. A flashing check engine light came on for 10 or 15 minutes. After stopping car and restarting it, the check engine light went off. 9/15/25: Car jerking and another flashing check engine light. Took to dealership. They drove it and said no codes stored. Told it was probably the transmission "breaking in." Took home. Car continued to jerk/stumble. 8/28/25 to 9/15/25: Car jerking and flashing check engine light back on. Took to Autozone. A Random/Multiple Cylinder Misfire Code was detected (P0300). Took to dealership and confirmed P0300 Code stored. GM TAC engineers involved. Told they were unable to figure out why car was having multiple misfires. Returned car to me because no active code/light. 9/29/25: Car jerking and flashing check engine light back on. Got a warning of "reduced acceleration and drive with care." Car lost power. I have video of this and contacted On Star with report generated and P0300 code. On 10/1/25 on way to dealer, car making audible ticking noise. I have video of this. Took to dealer, the ECM was replaced and oil changed because it was "very dark" (in vehicle with 4,600 miles). Car continued to jerk/stumble. Told by dealer that problem would have to get worse before diagnosis could be made. 10/31/25: Jerking and another flashing check engine light with "reduced acceleration drive with care warning." Turned car off and engine light off. On Star report P0300. Took to dealer. The dealership was given the videos of check engine lights/reduced acceleration warnings and ticking noise video. All show problem happening around 1,200 rpms. Told by dealer on 11/11/25 that GM rep said they will not pay dealer for any work because no active engine light/codes. Told to pick up car. Asked dealer today for reason in writing, but no response. Very concerned about vehicle safety when repeatedly going into limp mode and flashing check engine lights with GM offering no solution.
