2020 Chevrolet Silverado steering problems

“While driving I lost the power steering on the vehicle. I took my truck to a chevy dealership and scheduled an appointment for the following day. I research the problem and found that there was a Customer Satisfaction Program bulletin (N252515590) issued covering this specific issue for my trucks model year but it did not cover my specific VIN. I contacted Chevrolet Customer Assistance and they told me to file a complaint with NHTSA.”

“Body to frame ground cables corroded in half two different times within about 6 months. First time engine wouldn’t start had to have it towed to dealer for repair, over 30 codes were shown when this happened. Next incident some of my lights were working intermittently and my steering was rendered inoperable for 20 to 30 seconds at a time making it impossible to steer the vehicle, several codes were found when this happened, I drove the truck to a Chevrolet dealer for repair. Both repairs were deemed to be corroded ground cables. Chevrolet has a “customer appreciation program” covering 2019-2024 Silverado trucks but for some reason my VIN number doesn’t land in the program even though it has the same issues that are covered for the other silverados.”

“On July 22, 2026 took truck to dealership for oil change and reported getting random (trailer brake, power steering) service alarms. Was told it might be a ground strap issue and was sent on my way. After investigating, there is a GM service bulletin (#23-NA-201) on the issue but does not cover my truck. After a week of vacation, began driving truck again and alarms became more frequent, including loss of power steering and jerking of steering wheel while driving. Arranged with dealership to replace the ground strap (at my expense). By the time they could schedule, the alarms were constant and the truck had completely lost power steering. One of the power steering failures nearly resulted in an accident while turning.”

“Intermittent issue where info says brake failure/steering assist not working/limited speed to 43 mph. Very dangerous if you’re on the interstate. Becomes hard to steer, brakes don’t work, brakes start burning up. Have to carry tools with me to reset ecm. Very common problem with Silverado with 5.3 gas engine. Chevy needs to fix this issue before someone gets killed. I would give them my truck back if I could.”

“In several situations, I have lost partial or complete power steering ability. Once, while driving, I recieved a SERVICE ESC message and steering became quite difficult. Another time, power steering was completely gone, making steering impossible, although every other aspect of the vehicle operated normally. In both instances, there was no clear issue and after some time with the vehicle parked and off, it would return to normal. Possible loss of power steering unexpectedly is a serious concern at this point.”

“Intermittent and sudden loss of power steering. The only message displayed briefly then went out was “service trailer brake controller”. Brought vehicle to Dealership. The grounding strap behind the front right wheel that goes to the frame (Earth Strap) was rotted. This seams to be a very common problem with this model truck and is dangerous.”
