Drove to sams club and returned to my truck an hour later. Turned on the truck and I had a service power steering message, drive with care warning as well as service ESC. It was really hard to turn the steering wheel. I turned off the truck and pulled out the manual. After 5 minutes, I turned the truck on and no change. I kept reading and about 15 minutes later I turned on the truck again and this time the steering was back to normal with no dash messages. I drove home and scheduled an appointment for 12/14/202 with my dealer, ancira Chevrolet, san antonio, Texas. I read on the internet that other Silverado owners are having the same problem. My truck only had 4,529 miles when this happened.

Traveling at about 75-80mph, on a highway, - brakes engaged, slowing vehicle by about 15mph causing the truck to jerk as if it missed a gear. "service ESC" diaglogue, traction control light, and check engine light came on.

After parking for about an hour started the truck and got warnings for service ESC and service power steering, drive with caution. Turned engine off and on a few times, no change. Called onstar, they said they could send roadside assistance, I chose not to get the service as we were in the middle of nowhere down a single track dirt road. Drove home with no power steering, traction warning light on the whole way. Turned engine off then on again and the issue was resolved. It looks like there have been service bulletins/recalls for similar issues but nothing active on my truck with 2100 miles. Software/sensor problems like this can lead to very dangerous situations. Thanks for the work you do at NHTSA

I went in the store this afternoon, when I returned to my truck and started it up I had a service power steering drive with care warning as well as service ESC. I shut the truck off, waited a few minutes and restarted the truck, the warning was still there so I called the dealer and they sent out a service tech and service mgr, they couldn't figure it out and had it towed to back to the dealer the truck only has 1400 miles on

The following all takes place while driving the vehicle on the interstate and city, at higher rates of speed and when traveling at a slower speed - which is an extreme danger - every dash warning light came on and warning messages flash (brakes, steering, trailer, fuel, etc) roll from message to message, brakes get soft and hard to stop, truck tried to stall and slowed down like it was losing power (this happened while rolling at 45 mph), ac stopped working (fan working but cold air stops), truck lunged forward while engaging the brakes to slow down at a red light, steering definitely stiffer due to lack of power assist. These same messages and warning lights will also continue to flash when the truck is parked. This issue started at 3300 miles on July 8th, then it happened again July 24th, then again Aug 4th/5th.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while pulling out of the driveway at approximately 5 mph, the brake pedal was depressed and went to the floorboard before stopping the vehicle. The check engine and service braking system warning lights were illuminated. Additionally, the engine power reduced and power steering assist failure messages were displayed on the instrument panel. The contact stated that the power steering was temporary and returned to normal operation. The vehicle was taken to joe basil Chevrolet (5111 transit rd, depew, NY 14043, (716)683-6800) to be diagnosed. The contact was informed that the braking system needed to be reprogrammed. The contact was informed that the brake failure was related to NHTSA campaign number: 20V116000 (service brakes, hydraulic). The recall repair was performed. The mechanic was unable to identify the cause of the power steering failure. The manufacturer was not made aware of the failure. The approximate failure mileage was 1,451.

Started the engine and had no power steering. I had a message that said service ecs I believe. Power steering has started working again since.

- Fort Myers, FL, USA

On two separate occasions: On the highway at speeds of approx 50-70 mph, the power steering feedback while moving through a left curve failed. The wheel did not react back to the center when the steering wheel was "let go". the steering wheel felt "dead" and stayed in the left turn position. When coming out of the left turn/curve, the wheel had to be forced back to center. Pulling over and turning the truck off and then on, seemed to fix the issue temporarily. Feels extremely unsafe.

- Lakewood, CA, USA

It happened after driving on the interstate, we pulled into a gas station and when we got back on the road I found the list of warnings and I lost most all braking and power steering and had a dash full of lights telling me all sorts of warnings. I pulled over on the interstate on-ramp and turned it off and back on and the problem continued. 'service parking brake' 'traction control off' 'engine power is reduced' 'brake system failure" 'service ESC' 'service trailer brake system' 'steering assist is reduced drive with care' "speed limited to 43 mph"
