6.2 engine with catastrophic engine failure. No warning prior to failure.

- Hawley, MN, USA

My two children and I were traveling to another state and had been driving about 2 hours when the engine in my 2022 Suburban suddenly quit working while I was in the middle of a highway. I had just accelerated and merged onto a multi-lane highway moving all the way to the far left lane when my engine completely went quiet and seemed to quit working. The car all of a sudden shifted into Neutral and started losing speed. I had to put my hazard lights on and cross back across the lanes to get back over to the emergency lane on the right all while losing speed. We were all pretty scared because the Suburban just seemed to quit working and wasn't responding. I'm thankful we were able to get safely to the emergency lane before the car completely stopped. Once I was in the emergency lane, I tried to see if the car would go back into Drive position but it would not. I turned the car off and waited about a minute and tried to power it back on but the only thing that worked was the electrical stuff in the car (the screen for my dashboard and car play/nav system) and the engine remained quiet. Once the tow truck arrived an hour later, the worker tried to jump the engine but it did not respond. It was obviously scary and has been a huge inconvenience but it also left us in a very unfortunate situation because we were in a different state and did not know the area or anyone nearby that could come and pick us up once the tow truck arrived. I was pretty much stranded with my 2 daughters and all of our luggage in a different state on the side of the road.

The -??add engine oil-?? light kept coming on and I initially thought it was because they forgot to reset it after my oil change because my car wasn-??t reading it was due for one. I came to find out that my car is likely burning excess oil, according to the dealership, since all of the oil was gone. GM says that it-??s normal to burn oil and as long as it-??s up to 2 quarts between oil changes it-??s fine. The dealership recommended that I get oil consumption test and sometimes it burned more oil than normal and other times it did not. We had to go every 1,000 miles which was an issue because it-??s our main vehicle for family transportation and sometimes I would have to go under 1,000 miles because we needed it for a longer trip and would be over if waited until we got back. Also, my engine fan was making a very loud noise that would run for a while after my car was turned off and I was told multiple times it was fine until one time they checked it and it was indeed an engine malfunction and my engine would overheat when I went above a certain speed. The first fix wasn-??t right and had to go back. I wasn-??t burning enough oil to warrant GM to do anything.

As I was driving, in July of 2024. I noticed that that I had a traction control system warning on my dashboard. I didn-??t think of it to been serious. Then all sudden the engine kind stalled. So the car wasn-??t going passed 40 miles per hour. So I managed to take it to dealership. Once there the technician mentioned to me that I wasn-??t alone with this type of engine failure. He added and showed me another suburban with the issue. He said that the engine needs to be completely replaced. Because there is metal in the the oil pan. He added the cost of the repair would be $8000 to $12000. So that-??s when I decided to take the car to the automation Chevy dealership. They confirmed the issue and charged me $8200 to fix it. I really expected GM to cover the cost. But I was that they would not. Upon further research I found out that that many people had the same engine issue. I am hoping that the government should take action to investigate these engines failures. I think GM failed his customers especially in the COVID era of 21 and 22. Thx

While driving my vehicle, it suddenly shook, a vibration started, and then the car began misfiring. I own two Chevrolet Suburbans, and since the same issue had happened before with the other one, I was more experienced this time. However, this time, there were also unusual noises coming from the vehicle. It wouldn-??t accelerate, kept shaking, and multiple warning lights appeared on the dashboard, such as Engine, Traction, and ESC. The issue occurred as I tried to move forward after waiting at a red light. Since I had experienced this problem before, I immediately pulled over to a safe spot, ensuring our safety. I took the car to a different nearby mechanic. The mechanic stated that this is a common problem with these vehicles and that they encounter it quite often. I explained the previous incident I had experienced. The mechanic confirmed that the engine needed to be replaced. I purchased a new engine from Chevrolet and had it installed by the mechanic. I have already submitted a complaint to you regarding my other vehicle, which is the same model and year. I own two 2022 Suburbans, and both had their engines replaced within the past two months. The removed engines were sent to Chevrolet, but I have not received any information regarding the condition or cause of failure.

While driving my vehicle, it suddenly shook, a vibration started, and then the car began misfiring. It wouldn-??t accelerate, kept shaking, and several warning lights appeared on the dashboard, such as Engine, Traction, and ESC. At that time, I was with my two sons, aged [XXX] and [XXX]. We were turning onto an empty and quiet street, so our safety was not at risk. However, if this had happened in heavy traffic, it could have posed a significant danger, as the vehicle-??s power dropped dramatically, and it all happened very suddenly. I took the car to a mechanic. Initially, the fuel injector was replaced, but the problem persisted, and the mechanic recommended an engine replacement. After that, I went to an authorized service center, and they also recommended an engine replacement. I purchased a new engine from Chevrolet and had the mechanic install it. The mechanic told me that this is a common issue and mentioned that two other Suburban engines were replaced this year. My next complaint will also be related to my second vehicle, which is the same model Suburban, experiencing similar issues. I own two 2022 Suburbans, and both have had their engines replaced in the past two months. The removed engines were sent to Chevrolet, but I have not received any information regarding their condition or the cause of the failure.

While traveling back from Labor Day Weekend on [XXX], I was driving in the Dallas Fort Worth area when I experienced loss of power to our vehicle on a major highway [XXX] and [XXX] ) and directly on a bridge with my entire family in the vehicle (4 kids and all of our luggage). It was a very dangerous and scary situation. We had to wait one hour for a tow truck to come and take my vehicle to the closest GM dealership. I was left stranded, 3 hours from my home with my four children and luggage. The Chevrolet dealership contacted me 9 days later and informed me the technician looked at the vehicle and determined the engine was locked up/seized. It would take 9 months to get the vehicle back into the shop to determine what caused the issue and then take 6-12 months for a new engine. I have a family of 6 and I'm left car-less for two years. Yet I still have to make the monthly payment on a vehicle that I won't be driving or be in possession of. MY BIGGEST ISSUE: GM has known that they have had engine issues for many years. Particularly, with Dynamic Fuel Management causing lifter issues which leads to engine failure, yet never disclosed this to me when I purchased the vehicle. Furthermore, they never disclosed that the issue was so prevalent that motors were back ordered for over a year. Consumers are being misled into spending their hard earned money on vehicles that have major mechanical design flaws known to the manufacturer. Once the mechanical flaw is realized, the vehicle can't be repaired for up to two years. Hiding this data from consumers should be criminal. Furthermore, General Motors to this point has been no help, with the GM customer satisfaction team telling us they can't do anything until a dealer diagnosis the issue, and the dealer stating they can't diagnose the issue until May of next year, at which time they would then look to order the motor which will take 9-12 months to deliver and install.
