2020 CHEVROLET SILVERADO 1500 Complaints

As I was backing out of a parking spot in a lot my vehicle lost it's power steering. I got an Service ESC error code, a wrench indicator, and a service power steering/drive with care warning. I also got a diagnostic alert from On Star. Diagnostic Alert: Service Antilock Breaking System in your 2020 Silveragod pithing the next 7 days. I was unable to move steering wheel, and could only pull my vehicle forward. So it was stuck sideways in the parking lot for about 20 minutes. My car did restart again and the code cleared. I was able to drive it to the dealer. They ran diagnostics but were unable to duplicate the concern. They did find a history of 1 fault where several modules (ECM, EBCM, TCM, TCCM) had lost communication with the power steering control module. They also looked at Data Com schematic doc 5257308 and found modules before connector X182 had lost communication. My safety was a risk in this situation because I was stuck sideways in a parking lot with very limited ability to move my vehicle for incoming or outgoing traffic. Had this happened while I was driving the vehicle in a roadway I believe it could have caused an accident. The dealership did find that a harness was making contact with the upper control arm bolt. They re-taped the harness and secured it away from the control arm bolt and bracket. A new bracket was ordered.

I was driving and a few different warning appeared. Service Parking Brake, Service Trailer Brake System, Steering Assist is reduced Drive with care. Along with these warning my speed was limited to 62 mph, my steering was reduced and my braking was reduced, all 3 of them to dangerous levels.

I am a volunteer firefighter. On Friday, June 24th 2022, I was responding to an emergency call around 1am. There was an active rainstorm and standing water on parts of the street. While driving through roughly 5-6" of water on the way to the fire station, my truck's engine suddenly shut off and I came to a stop. While stalled, I watched multiple cars travel through the same intersection with no issues. My fellow firefighters helped me get my truck to a nearby parking lot to sit and dry out. The following day my truck still would not start so I had it towed to the dealership where I leased the truck which was still under a full bumper-to-bumper warranty. After initial diagnostics, I was told there was water in my intake and I had to get my insurance company involved for the dealership to continue with the repairs. With no other choice, I opened up a claim and was given an estimate of over $9,500 for the repairs due to the engine being "Hydro-locked". I called GM and filed a complaint. They called the dealership and called me back stating the dealership told them I drove through a flooded road and damaged my engine. I did some brief research online and found several examples from multiple sources with the exact same issue. I feel that this is a design flaw and that this needs to be investigated further as I was stranded by myself, in a heavy rainstorm, in the middle of a roadway at 1am. There is no reason that a 2020 Chevy Trail Boss should not be able to travel through the amount of water that stalled my engine. There was nothing negligent about my actions and at no point was I worried about traveling through the water that I drove through. I feel like I am being treated unfairly in this situation and I would like someone to look through the databases to see how many similar consumer reports there have been regarding this design flaw. This is a major safety issue!

The component that recently failed on my 2020 Chevy Silverado is the side detection/blind spot warning. It no longer works and upon startup of my vehicle the notification on my dash shows “side detection temporarily unavailable”. This problem started 3 weeks ago. After doing research online, it seems that there is a common issue in Chevrolet vehicles with water getting into the rear sensors in the bumper. There were also several new model Silverado’s with the same issue. As you can see, this is a safety issue as this feature all of a sudden stopped working on my truck so I no longer get warned if someone is in my blind pit while I am driving. I contacted my local Chevrolet dealership and they stated that because my vehicle is over 30,000 miles (36,000), I am no longer covered under warranty to have this issue repaired. My vehicle is scheduled to be looked at by the dealership on 6/27/22.

Transmission shuddering and shaking while driving. Once in blue moon service light flashes for less than 1 minute then goes off with no diagnostic codes to show.

ABS light came on during breaking to avoid an accident and did not break the vehicle at all. Now there is a alert on the Driver Information Center(DIC) stating a break system failure.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while stopped in her driveway, the vehicle started rolling forward. The brake pedal was depressed aggressively several times however, the brakes failed to respond. After several attempts, the vehicle came to a stop. The vehicle was taken to the dealer where the mechanic stated that the failure could not be duplicated. The manufacturer was notified of the failure however, there was no response. The failure mileage was 14,562.

I have been researching rust on frame components and found there have been service bulletins issued (e.g. PI0564K) for this same issue. However, the latest service bulletin only covers up to model year 2019. Is there anything in progress to extend to model year 2020?

I bought the truck a year ago drove it home it stalled out on me for no reason thank goodness I was in a neighborhood when that happened, fast forward a year of driving it and now my gauges aren’t working it’s throwing all these warning signs and spent a lot of money on this truck and for what for all these problems that it’s having it’s my only vehicle for my kids and me and the wife and now I’m worried it’s going to cause me to get into an accident.

When I drive this car on the free way or on a very windy day, a loud air gap is caused by the front driver and passenger window. It hasn't been inspected by the dealer or anything but I believe there could be something wrong with the quality of glass or the seal that hold the glass. I've also driven with the windows lowered on a windy day and saw the edge of the glass bend. I'm worried it's gonna snap or shatter one day. It's been happening since I bought it but I didn't notice until I drove on the free way.
