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.

When I would put the truck in park and proceed to turn it off, the computer would tell me the truck was not in park. I was told at the dealership that the transmission was in park, though the computer wasn't communicating correctly. Not only does it pose a risk of draining the battery, it is a safety issue. If I were to park on a hill, the only confirmation that my truck is in park is what's said on my dash.

Transmission is giving the same issues as the reported diesel transmission problems in same year model. Safety has not yet been put at risk. Due to a 2 month wait time I have been unable to get it inspected by a dealer.

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.

Hard shifting and shuddering

- Gilbert , LA, USA

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.

- Avonmore, PA, USA

Transmission shudders and has a delay in shifting/starting movement of the vehicle. This problem was noticed at 98k miles about a thousand miles after I purchased the truck from a dealership. It has been inspected, and repairs scheduled, but the transmission is still on back order after 5 months of waiting. No part ETA is available from Chevrolet corporate. This issue is a safety concern due to the fact that the vehicle could hesitate to accelerate in the event of needing to take evasive maneuvers to avoid an accident/road hazard.

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.

Truck has been burning oil since it was purchased new in 2020. The truck has needed 6 quarts added between every oil change. It has been to the dealer and they insist nothing is wrong. GM customer service has been no help. Motor has a ticking noise. Finally 2 weeks ago check engine lights came on and loud noises came from motor. Brought it into the dealership and they said full lifter failure and engine scoring and has been like this for awhile now. This is something I brought up to them AND GM support over the last 4 years of owning the vehicle and they always told me there was nothing wrong with it. Private extended warranty is going to cover a new engine, but is on national backorder due to all the issues with the 6.2L engine and others having issues GM won-??t acknowledge.
