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?

Component/system that failed: The transmission control module in my 2020 Chevrolet Silverado 1500 has malfunctioned. The vehicle has issues with slipping between gears, rough shifting, and hesitation when accelerating. This component has already been inspected and diagnosed by a certified Chevrolet dealership, and the part is currently on backorder. The vehicle is available for further inspection upon request. Safety risk: This issue poses a serious safety risk to myself and others. The gear slipping and delayed response when driving-?"especially when merging onto highways or changing lanes-?"creates unpredictable behavior that can lead to an accident. The truck sometimes fails to engage gears properly, which makes it dangerous in traffic situations. Diagnosis confirmation: Yes, the problem has been confirmed by a Chevy dealership service advisor (Jose Diaz), who provided a formal quote and diagnosis for the replacement of the transmission control module. Inspection by others: The vehicle has not been inspected by police or insurance representatives, but Chevrolet Customer Assistance is currently reviewing the case, and I was advised to submit this documentation. Warning lamps or symptoms: There were no warning lamps initially, Symptoms include slipping gears, hesitation when pressing the gas pedal, jerky shifting, and difficulty accelerating smoothly. These symptoms have progressively worsened over time. Additional context: I have learned that many 2020 Chevrolet Silverado trucks have been recalled for the exact same issue, but my VIN is currently not included. I believe this is a manufacturing defect and that my vehicle should be considered for inclusion in the recall or further investigation.

Front main bearing failure. I have 97,000 miles on my truck. I have the 6.2 engine in it. I see online that GM is having a lot of issues with this engine. My dealer is trying to help me deal with GM, but GM does not want to replace my engine. They want me to pay for it. This issue could have been bad if I was driving at highway speeds with my 2 young daughters in my vehicle with me. Definitely a safety issue.

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.
