2020 CHEVROLET SILVERADO 1500 Complaints

Driving on highway truck lose power, engine lights start to flash and cracking noises start to come from engine. The lose of speed almos cause another vehicle to rear end me, Truck gave no signs or warnings before. Truck was delivered to a local shop and due abundant amount of metal flakes in oil engine need to be replaced

While driving at highway speeds, multiple warning lights illuminated on the dashboard at the same time, including engine and powertrain warnings. The vehicle suddenly began operating abnormally, with loss of power and unstable driving behavior, making it unsafe to continue driving. This same issue has occurred multiple times previously and the vehicle has been taken to an authorized Chevrolet dealership for repairs on three separate occasions. Each time, repairs were performed, but the problem returned. The most recent incident occurred while driving on the highway and created a serious safety risk to the driver and other vehicles. The vehicle is not safe to drive.

Back in 7/2025, I was going to a Dr appt in Chandler, Az. When I arrived in Maricopa, Az, my truck stalled at the first stop light and would not start. I went over Kraegan Auto parts and bought a battery. After about 10 days, I was having to jump start my truck for the next few days. I took the battery back and they realized that it wasn’t the battery my truck called for. So, now I have the correct battery and everything working like it supposed to. In Nov 2025, my battery was starting to drain like overnight, and jump starting my truck every morning. I also told them, that the transmission was acting up. When I got on the highway my truck would be at 5000 rpm while doing 60 mph. I be would have to pull over to side of the highway, shut the engine down, and restart. Usually it would be good after the first time. So, up until now, I have no heater, no AC, my windows don’t go up or down, cruise control don’t work, l can’t move my power seat, so my wife has to put a pillow behind her and a pillow beneath her when she drives our truck. And I be still haven’t mentioned all be the little icons that are lit on the steering column. My truck is at the Jerry Seiner Casa Grande, Az. I have the protection plus coverage on my truck with GA Security, and I was told that because it’s a battery issue and found me at fault, they won’t cover me and I need to pick up my truck, because I can’t afford a $680.00 price tag. I’m on Medicare. That’s why I paid the $3500 for the protection plus coverage. So I guess it’s my fault or fault of my battery, my transmission doesn’t shift gears, power windows don’t work, heater or AC don’t work, can’t forget the cruise control. They said they are not covering nothing, to come get my truck.

On Sunday Nov. 16th, my steering wheel felt like it was "slipping", akin to how it feels when your serpentine belt tensioner is failing. I checked it out while wife turned the wheel, didn't see any problem, and we went on our way. Later in the day as we were leaving a parking lot, the problem occurred again but worse. And we got a warning about trailer brake controller needs repair. After reviewing similar problems on Reddit, I found it was still safe to drive, so we drove home without further incident. Monday I decided to take it to O'Reilly auto parts and have a code scan done. Except, as soon as I turned out of the driveway, my wheel completely froze up solid. I could NOT move the wheel (q2)! Since the wheel was still turned, I backed it into the driveway and we took our car to buy our own code scanner. It showed more than just one fault code for the brakes, there were 5. I called Fox Chevrolet to schedule al appointment for the next day. Fortunately, the failure occurred as the Advisor attempted to turn the wheel (q3). Long story short: problem was a rusted/rotted out ground wire (q1)! Behind the front driver side tire, encased in a boot. Tech told the Advisor he'd never seen that one before. $40 part, and $400 to install it (q4). I was happy it wasn't a power steering rack failure (electric) but the more I thought about it, felt I needed to report this. You needed a dealer scanner to catch this and trace it to a ground fault. Probably better for you to contact dealer Advisor and Tech to get a better breakdown on this (q1). Dealer was great, they could have sold me an $1800 steering rack and I'd have never known. Could this failure have happened to someone driving on the street and this pop up all of a sudden (q2)? I believe so. Glad I didn't find out firsthand. The problem went away overnight twice, and then all of a sudden your wheel is LOCKED. I'm curious as to if others are or have faced this, thus my submittal. Thanks for your time.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that upon starting the vehicle, there was an abnormally loud engine camshaft bearing sound coming from the engine. The engine warning light was illuminated. The vehicle was taken to the local dealer, and after three days, it was determined that the camshaft bearing had failed, and the engine needed to be replaced. The vehicle was not repaired. The contact linked the failure with NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling) and NHTSA Action Number: EA25007 (Engine and Engine and Engine Cooling). The manufacturer was contacted and opened a case. The failure mileage was approximately 45,000.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while starting the vehicle, there was an abnormal odor coming from the vehicle.

The dealer informed the contact that the coolant control valve, motor mount, and wiring harness needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for further assistance. The approximate failure mileage was 88,000.

My 2020 Chevy Silverado needs a torque converter replacement. My truck is at 90k miles and out of drivetrain warranty. However, this is a known GM problem with trucks (and other vehicles in this class of engine/transmissions). I have talked to GM corporate and they are only willing to rebate 20% of the cost of this repair. I believe they should pay for the entire repair since this is a known problem for all these vehicles in this class. Please help me to get GM to understand this and fix this known problem.

Sudden intermittent loss of power steering, issue confirmed by Chevy Dealership. No warning lights were displayed.

Transmission, would lock up for no apparent reason . At random speeds, they continue as if nothing was wrong. Took to dealership, couldn't get to it for a week. End up at a transmission shop said it through some code. required rebuilding the transmission . 88,000 miles on truck. From time of first incident to first shop visit one week. Same transmission in similar trucks is under recall but this vin# is not.

THIS IS A RECALL REMEDY FAILURE REPORT UNDER 49 U.S.C. §30120. My 2020 Chevrolet Silverado 1500 (VIN: [XXX] ) received Recall 24V797000 on June 9, 2025. The ECM update is intended to detect incipient clutch-pressure or gear-ratio deviations—early signs of a developing slip—and automatically force limp mode to prevent rear-wheel lockup. On August 23, 2025, after the recall was performed, the truck experienced rear-wheel lockup at highway speed. Limp mode did not activate, which shows the recall remedy failed to operate as required. Mangino Chevrolet documented symptoms matching the recall defect, including abnormal ratio behavior. No metal debris was found in the pan, indicating the failure was not caused by wear. GM TAC also noted behavior consistent with a developing slip. GM first recommended full transmission replacement at my expense before acknowledging the recall. GM later authorized a valve-body replacement, which also failed. The dealership owner provided a written statement confirming that: (1) the recall remedy did not correct the defect, and (2) the valve-body repair did not correct it. On December 3, 2025, GM Customer Assistance attempted to close my case as “not recall-related,” despite the post-remedy lockup, limp-mode failure, dealer findings, and the written admission that the recall remedy was ineffective. The safety defect persists after recall completion, and GM has not provided a remedy that corrects it, as required under federal law. I am reporting this as a failed recall remedy and an ongoing safety defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
