From the time my vehicle had 30,000 miles on the engine, the engine light would come on and stay on with no apparent reason. I would take my car to my local Chevrolet dealer each time (by this time the light had gone out) and they could not find a problem. One technician told me that it sounded like a lifter problem that they were experiencing with these model vehicles. This happened approximately 8 to 10 times before the lifter failed. In January 2025, while driving on the Interstate Highway I experienced a sudden engine vibration and immediate 50% loss of power. Upon returning home, I took my truck to my local Chevrolet dealer where I purchased my vehicle. Upon inspection, I was told that it was apparent that a hydraulic lifter had failed. I left my vehicle at the dealership for the repair of the failed lifter which cost me $4,800. Two months later, I experienced the same problem with the engine, more violently vibrating. I again took my vehicle to the dealership and they confirmed another lifter had failed and took it in for repair under warranty from the prior lifter repair. I had again experienced more than 50% engine loss and had to get off of the interstate and travel on a side road because I could not maintain a speed over 45 to 50 mph. They repaired the same failed lifter bank that they had repaired the first time. Now, I am holding my breath, just waiting for the lifters on the other bank to fail for me to have to put in another $4,800-$5,000. I believe that this is an engine flaw that Chevrolet knows about. They have done nothing to fix this issue and have left it on the backs of the customer. Chevrolet needs to be accountable for these types of problems!

Engine misfiring multiple times over a period of 2 or 3 years. Took it to the dealership in Andrews Tx, could not duplicate misfire but saw over 600 misfires on a single cylinder, they said it was fuel pump failure. Replaced fuel pump. After a month misfiring started again. October of 2024 took it to dealership in San Angelo Tx, they were able to duplicate misfire, lifter failure. Replaced lifters and cam as it was beat up. One month after repair, vehicle started shuddering. Took it back to San Angelo service center, transmission issue, torque converter needs to be replaced. I refused the service as I would not spend $5,000 more after spending $10,000 to repair engine.

I purchased a 2020 Chevy Silverado 2.7 turbo RST from Greg young Chevy in Omaha Nebraska. Upon purchasing this vehicle within 20 days of ownership I got a check engine light indicating code P2090 for exhaust camshaft position sensor. The truck was taken back to the dealership and they at first tried to just clear the code and give the truck back however I put my foot down and requested them to look further into it. After weeks of them having the vehicle they determined there was an issue with the pcv oil separator and they replaced the part allegedly. After reviving the car back they strongly suggested I purchase an extended warranty telling me -??you-??re going to need it-?? we purchased the warranty only to discover the code reappearing less than 2,000 miles later and a tic sound in the engine. My independent research has concluded it-??s a lifter failure and those lifters are now slamming into my camshaft causing excessive damage. After getting the code read more in depth I can confirm they again just cleared the code and an oil leak is still existent in the engine. This causes the auto stop to disengage which makes the vehicle leech forward when at rest while my foot is still present on the brake as the camshaft does a full rotation to adjust and correct itself to the sensors suggested position. On average this moves the vehicle approximately 1 foot forward and could lead to me damaging my vehicle or causing harm to people in crosswalks.

The engine is blown. Our GM Dealership where we purchased it, inspected it and says the engine cannot be repaired and must be replaced. And independent garage gave the same diagnosis. Went from running fine one day, to bucking and stalling in traffic causing a hazard to everyone on the road. Check engine light, check brakes, stabilitrak, ALL the lights on the dash were on like a Christmas tree. It doesn't run now. Currently sitting in our driveway now unable to be driven for three months as we don't have $10,000 for a new engine, and the extended warranty we purchased through the dealership expired 4 months before it blew up. We are now making loan payments on a GM vehicle that did not even last the length of the loan. Seeing a report on this exact issue, we did not even know until today that there was a place we could send in a complaint to. You are welcome to inspect the truck, but you would need to come to us, as it cannot be driven. Where can we get any help with this? Please help.

Vehicle started miss firing along the highway without any previous signs of problems. The vehicle was driven straight to our home and then to the dealership a few days later. We were told there, the lifters have failed. Once they started the repairs we were also adviced the cam have suffered significant damaged and needed replacement as well. The vehicle was only inspected at the dealership once it was dropped off. The first and only sympton of the insurance was the day it failed.

On January 17, 2025, I was approaching the entrance ramp unto Interstate 10, traveling along at approximately 40 miles an hour, when all of a sudden I noticed that my vehicle started decelerating as I was pressing on the accelerator, trying to merge onto oncoming traffic. The engine started shuttering and vibrating violently! I noticed all the warning lights, gauges and indicators had come on simultaneously! There was a loud clicking sound coming from the engine compartment and backfiring coming from the exhaust. I evaluate the situation at hand and conduct a risk assessment of trying to continue on with this problem but decided to move over to the median. I was almost run into from the rear due to lack of power in which I felt would have been the result of my truck just losing power without any warning. I drove my truck to a Chevrolet dealership after speaking with a Service Advisor, on January 20, 2025. The Truck was diagnosed as needing to replace Cam Rod and Lifters.

At roughly 146,590~ miles the truck began making a knocking noise while driving at any speed, complainant had the truck towed to independent shop and was evaluated. Was told by shop that the engine can shaft pitted and engine metal shards had exploded and shattered throughout the engine. Making the opportunity for engine stalling or risk of fire/ smoking while operating the vehicle extremely likely. Complainant was told there was no access to engine replacements or parts at this time and the wait time to receive one was 4-6 months. No warning lights ever went off. Engine was eventually replaced entirely when the part became available by an independent service dealer.

Vehicle purchased December 2020 Flashing check engine light that stays on- light did not stay on long enough for dealer to see, said they couldn't find any issues. The first time we had it towed and when they looked at it the light was no longer on. They were able to tell us what was going on with the vehicle when the light came on but said there were no problems. Flashing check engine light that turns off- "no light = no problem" dealer says. Eventually they printed pages showing engine misfires which we were initially told was no big deal. Later I was told I should get spark plugs changed, which I did. So far, flashing light has not reoccurred. Burns 3 or more quarts of oil between oil changes which I was assured by more than one rep that that was normal (on numerous occasions). Air conditioning quit working. Heater not working well and not at all on idle. The only setting I can really use to defrost and keep my feet warm is the "floor only" option. Mixed doesn't work, defrost only will freeze feet. Gas smell while vehicle at idle. Initially noticed when using auto start but have since noticed it does it with regular start as well. All issues have been brought to dealership, I will have to contact them for all the exact dates.
