2021 CHEVROLET SILVERADO 1500 Complaints

While traveling on Interstate, the Check Engine light, Electric Parking Break service light, and Traction Control Light displayed for about 10 to 15 seconds. They all turned off at the same time and have not turned back on since. No limp mode was Vehicle has Service code for Engine Misfire with no cylinder indication. Spark Plugs, spark plug wires, and Coil Packs have been replaced. Vehicle has random flashing Check Engine Light for about 20 to 30 seconds while traveling above 30mph. Vehicle hesitation (jerking back and forth) is observed at continuous speed at 45mph and 51 mph. Vehicle has been brought to dealership for evaluation with no repair being completed. Dealership is not able to replicate issue.

When you drive the truck for at least an hour then you turn it off the entire front like vibrates or shakes . It almost feels like something is still turning in the transmission but everything is turned off. This particular truck has already had the engine replaced at 14,000 miles bc it was faulty. It also has issues with tires. The radio and lights also all go off for brief time and then it comes back on. At times the drives side seat belt will lock and it pins you to the seat where you cannot move and you have to remove the seat belt. It is becoming more of an issue. I believe the transmission to be going out. Today, I wasn’t sure if the vibration in the truck was going to stop. So I stopped driving the truck and went and got another vehicle to drive

Electric tailgate opener button switch on tailgate failed and allowed tailgate to open while traveling. Lost a tote containing tools onto the roadway when accelerating from an intersection. Luckily it was a rural road with no traffic and no one hit tool tote in the roadway. This seems to be a serious safety hazard especially if a motorcycle would of hit lost cargo in the roadway.

Heard and felt a loud clunk from underneath truck while driving 70 mph on interstate. Pulled off and next available exit with a hotel and parked truck. Cranked truck to move and it would not move forward or backward except for about a foot. Loud grinding noise. Had to call tow truck to tow us to nearest Chevrolet dealer. Dealer service department says transfer case has seized up and must be replaced. Transfer case is currently on backorder and not available from GM. Was given rental car to drive home, which is 10 hours away. Truck has been in shop for 7 days as for this writing and I still do not have an answer about when a transfer case will be available and they can repair my truck. I located transfer case at my local dealer but repair dealer says they have to wait on GM.

While accelerating moderately, the transmission downshifted and momentarily locked up the read axle. This caused the rear of the truck to start sliding out. There was a loud bang, and when I checked my outside mirrors, I saw smoke from the tires. I almost lost control in heavy highway traffic. The entire event lasted about a second or two. I am glad I was not pulling a trailer at this time. I reported this incident to my Chevy dealer and informed them of the existing service bulletin on this exact issue. 21-NA-275. The dealer has not followed up with me on their conclusion or what they will do about this dangerous defect. No warning lamps, messages, or other symptoms before this incident.

My check engine light came on. When taking it to the dealership, they say it's the Catalytic converter. The converter is not an electronic part, so we replaced the o2 sensors and the check engine light came back on. I've taken this truck to several people who repairs cars, and The vehicle is only 3 years old , should not need to be replaced. A converter should last 10-15 years. In doing some Research, I found the the 2019 recalled for the ECM module. Causing the same issue as the faulty reading on a catalytic converter. I am now out of warranty due to being 2,000 miles over the limit.

- Warning came up that said to service power steering system. Steering wheel became extremely hard to turn. -I could barely complete my turn to get the vehicle clear of the road -Vehicle is scheduled to be seen by a dealer -No other parties have inspected the vehicle

When my truck is outside and gets rained on. The Tailgate automatically drops and keeps dropping over and over again. It’s been doing this for months. I have many safety concerns. I’ve had my tailgate open while driving. I had a young child standing behind my truck and it automatically opened. Recently over the period of the night it kept sending signals to drop annd lights would alol turn on until my truck battery was drained. I’ve looked up and saw other Silverados in my time frame with same problem with tailgate switch and have been recalled. This is 100 percent same thing going on with my truck. I have video but couldn’t upload below

Bulletin No.: 21-NA-275 Please refer to the posted bulletin. This known issue is absolutely dangerous and needs to be recalled. My truck will lock up going 50 to 60 mph to a complete stop and there's no warning. Gm needs to get all these vehicles fixed it's going to hurt someone or even worse. There's no warming lamps. I'm getting my vehicle into the shop as soon as possible. This issue again is very very dangerous.

The power steering locked when driving, this happened last year. I had it serviced at the dealership and it was fixed but it’s reoccurring occasionally. Now when you turn it on you could hear a sound and it’s hard to turn. It’s a safety concern for me and for others to drive it with that condition. I brought it back to the dealership to have it serviced again, a mechanic inspected it and confirmed there’s a problem with the steering but they will have to do a proper diagnostic with the issue. There ‘s no warning message that pops out.
