Two years ago, we had to have the transmission rebuilt after it kept slipping. Yesterday, as I was driving on I-95, I was passing a vehicle and pressed on the gas. There was a loud crunching noise and I lost acceleration. The check engine light came on right away and I couldn't press on the gas without a noise and limited forward momentum. I then had to maneuver the car across four lanes of traffic with limited control over speed. There was no warnings an issue was going to occur. We had it towed to our mechanic who said there was low compression in cylinder 1. Less than 90 psi. Again, we had already had the transmission replaced and now this major engine issue. We are in the process of getting it to a Chevy dealer.
Major engine failure in my 2019 Chevrolet Suburban Premier equipped with the 6.2L V8 engine (L87). Despite routine maintenance and responsible operation, the engine recently suffered a serious failure that has rendered the vehicle inoperable. After researching the issue and speaking with several service professionals, it appears this type of engine failure may not be isolated, but part of a broader pattern affecting similar models. Given the vehicle's relatively low age and the severity of the problem, I believe this may be indicative of a manufacturing defect or premature engine wear that should not occur under normal operating conditions.
Our transmission when out while driving at high speed down the road, which could have caused a serious accident. There was no warning light to alert the driver before this incident occurred. We had to pull over and have our car towed - and it was dangerous to be along side of the road. We had to pay over $4000.00 to have our transmission replaced and the mechanic, who is an independent dealer, said "in his opinion, the transmission problem was caused by the defective GM automatic 8-speed transmission". We have a detailed bill of all work completed by our independent transmission dealer - dated Feb 2025.
I was driving yesterday when my car began to shake at low RPMs. The traction control light came on steadily and the check engine light was blinking. I was unable to safely accelerate. I took it to my mechanic who tested spark plugs and coils, which he confirmed aren't the problem. He informed me that this is a common issue with the GM 6.2L engine, but mine isn't part of the recall. After checking online I see that this is exactly what many others are reporting and that there's an NHTSA investigation as well as a class action lawsuit tied to this issue.
At a stop light the stabilitrack and check engine light came on. Engine began running very rough. I pulled around the corner and was able to get into a parking lot. When I stopped the vehicle the car shutoff completely, including all the electrical. I tried to start the car but when I did there was no engagement of the starter and all electrical shut off again. Car was towed to a mechanic shop and was advised that the engine was seized after they could not turn the engine using manual means. I had to have the engine replaced.
