ENGINE
While highway driving on 4/8/2025, for the 3rd time in 3 months, engine light came on and I lost all control of my cruise control, parking brake disabled and loss of engine power immediately reducing my highway speed to approximately 50 mph which was very dangerous. I had to cautiously return home & called the Chevy dealer immediately. They had repaired the lifters twice before, with the most recent repair on the lifters and push rod just one month earlier. This second repair was covered under their repair warranty. Currently, it took about 10 days before a loaner car was available (after a poor google review). To date (4/30/2025) I have not received ANY feedback from the dealer (Starling Chevrolet in Mt. Pleasant, SC) regarding any repair or engine diagnosis. The symptoms of this third failure was just like the previous two failures (3 failures in 3 months!). I feel like this vehicle has Major issues as I have also had to have the radio/infotainment system replaced twice since the original purchase. PLEASE have Chevrolet do an engine recall on their 5.7 liter engine!!

ENGINE
While traveling on a rural state highway, the #8 lifter bearing failed, causing the engine to lose considerable power and the dash light to come on. No advanced warning of engine problems was noticed prior. The transmission also went into limp mode not allowing the vehicle to shift gears. At the same time the ABS and ESC systems also went into a safety mode diminishing the stopping power of the vehicle. Upon inspection by a licensed mechanic it was discovered that the #8 lifter bearing and the camshaft were both damaged at that time. Total replacement cost was over 10k and it took almost 6 months to find a rebuilt L87 engine at that time because there was almost no supply available as a result of these engines having multiple failures nationwide

ENGINE, POWER TRAIN
I just saw a recall for 2021-2024 vehicles for connecting rod/crankshaft engine components. I am not 100% sure that i have the same problem but my warning signs are the same. For example, there is a knocking sound in engin, it shifts abnormally and it hesitates and has reduced propulsion. I talked to several other Trail boss owners that had to have their Lifters repaired so maybe it is that? These problems are happening to everyone prior to even hitting 70k miles. I cannot afford to fix this if it is a problem that shouldnt be happening in the first place, due to crappy manufacturing.

ENGINE, VEHICLE SPEED CONTROL
Driving vehicle down freeway about 75mph heard noise and truck shut speeds down to about 60mph on a major freeway. Per mechanic lifter has collapsed and it has been a common issue that Chevy knows about. He said that it could have been alot worse by seizing the engine and causing harm to drive or other people around causing a major accident. There is a major safety issue to life and or death caused by this issue that has NOT been a concern and causing people to pay over $5000.00 for repairs. Chevy has known about the faulty lifters for years and doesn't seem to care about safety concerns.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
On Feb 10, 2025 while in busy mid-day traffic on the highway going 55mph my vehicle without any warning signs or warning messages on dash, or dash indicator lights suddenly went into limp mode , began making a loud knocking from the engine, and started shutting down. I stopped the vehicle as soon as I safely could do so and had it towed back to the selling dealer for them to diagnose the issue. The dealer then informed me that i had a bent lifter on the left bank but they did this based on codes and not any tear down. They referred me to another local dealer. I had my vehicle towed there where they also stated lifter. Once they began to replace the lifters on the left bank scarring was found on my #3 cylinder wall and at that point I was told that my truck had catastrophic engine failure and the engine would have to be replaced. They also told me that my truck had no oil in it and the issue was caused from carbon build up. I have had every maintenance service performed on time and at the selling dealer and have all service records. I was not overdue on maintenance. I have never been told about any oil leaks or any other issues that needed to be resolved on my vehicle. I had driven the truck the night before with no issues.. There was no oil on the ground or under the vehicle for them to say there was no oil in the vehicle. I was never told that i needed spark plugs due to carbon. I believe that this has to due with the AFM issue that GM is well aware of. I had to purchase another vehicle due to the damage that was found on this required an engine replacement

ENGINE
The engine failed while I was driving. It started to run very rough and then the check engine light came on as well as multiple other lights. I limped it to my mechanic who found that cylinder #4 had failed and rotated which tore up the cam shaft. Total damages came to 10,404.28. I have all receipts. Safety for myself and others were impacted because it lost power immediately and could have put me or other motorists in a position to react quickly not to crash.

ENGINE
The 2.7L turbo engine failed. The truck is available for inspection. All maintenance has been up to date. It was recently serviced for a seperate recall. The truck gave a reduced engine power message and within minutes lost power. A truck of this age, with maintenance done regularly should not experience engine failure.

ENGINE
The engine seized unexpectedly and without warning during driving. Being sudden and without warning it risked the occupants of the vehicle being injured as they struggled to get off the road and out of harms way on the road. The vehicle was taken to the nearest Chevrolet dealer to be inspected where we were told that the engine had suffered a total engine failure and would need to be replaced entirely. The vehicle WAS inspected and damage confirmed by the dealer at that time. Prior to the failure there were no warnings of any kind.

ENGINE, POWER TRAIN
At approximately 68K miles, the torque converter failed. Luckily it started going out and we could feel it. It would surge/shudder while driving on the road. We had to have the torque converter replaced at $5k. A dealer replaced the parts. At approximately 90K miles, the lifters started making a loud pinging noise. It turns out the lifters had issues which lead to them being replaced along with the camshaft. It could have failed on the road and left us stranded. The sound of the lifters alerted us. A local shop fixed the issue at a cost of $9K.

Had a check engine code and the dealership diagnosed the problem as being the coolant control valve. However being still under warranty they said that part is no longer covered under powertrain warranty as of Feb 1st. They now want me to pay 4400 for a part that fails often. Is there anything I can do?
