C0800 fault code: what 11 owners reported

I am writing regarding an issue with my 2016 Chevrolet Colorado that I believe warrants GM’s attention and consideration for assistance with the cost of repair. My vehicle recently began constantly dinging and displaying an error message on the dashboard stating “Power Steering Failure.” I took the vehicle to a mechanic for diagnosis, and the vehicle produced error code C0800, which references Technical Service Bulletin (TSB) #PIT5474D. After researching this issue, I understand that GM is aware of power steering-related failures affecting Chevrolet Colorado models from 2015 through 2021. What I am having difficulty understanding is why, if this was a known and recurring issue across…

ON THE FIRST OCCURRENCE THE LIGHTS ON THE RADIO DISPLAY BEGAN TO FLICKER AND THEN ALL ELECTRICAL POWER TO THE DASHBOARD. THE ELECTRICAL CAME BACK ON AND THE DASH DISPLAY DEPICTED THE WARNING MESSAGE CHECK STABILITRAK. I TOOK IT TO THE DEALERSHIP WHERE I PURCHASED THE CAR AND THEY SAID THAT HIGH VOLTAGE CODES C0800, 07 AND HIGH VOLTAGE HISTORY SHOWED UP ON THE SCOPE AND THERE WERE NO ISSUES. THE SECOND TIME THE LIGHTS ON THE RADIO DISPLAY BEGAN TO FLICKER AND THEN ALL ELECTRICAL POWER TO THE DASHBOARD, AIRBAGS AND THE ELECTRICALLY ASSISTED POWER STEERING WENT OUT, WHILE ON A VERY STEEP MOUNTAIN ROAD AND I HAD NO CONTROL OVER THE VEHICLE. THE ELECTRICAL CAME BACK ON AND THE DASH DISPLAY…

Our car broke down on 07/08/2021 and went into the shop on 07/12/2021. It was eventually determined the engine had to be replaced. The car was in the shop until 09/02/2021. The following day during a test drive I noticed some minor, unusual response, almost unnoticeable, from the brakes, but there were no warning lights or messages. I connected a code reader and received the following codes: U0422, U0151, and C0800. I think all of them are sent by the ECU and involve communication problems with the ABS and the restraint systems, but yet, no warnings. I took it back to the shop. They found a shorted or bad Body Control Module, probably caused during the engine swap. If I hadn’t found those…

As I was driving, my car decided to just turn off. All of the electronics turned off and I lost ignition. Moments later, while I was still rolling, the car turned back on. This issue has happened multiple times but nothing super serios ever happened and i was able to maintain control of the vehicle every time. Since it is a manual transmission, I was able to stay in gear and continue on. The issue with the steering came after the car turned back on. The "SERVICE POWER STEERING, DRIVE WITH CARE" message came across my screen. I used my scanner to see what the codes are, and it have me a "Power Steering Control Module" C0800-03 code, as well as a "Keyless Entry" U0140, a "Parking Assist…

I have read several things about EBCM and the control power circuit being above threshold and wondering if this is a recall for this model? I am getting 3 error codes C0800, B1325, & U0151 for this vehicle. (General Motors is recalling over 449,000 SUVs and pickups (2023–2024 Cadillac Escalade, Chevy Suburban/Tahoe, GMC Yukon, and select Silverado/Sierra 1500) due to a software fault in the Electronic Brake Control Module (EBCM) . This issue prevents the brake warning light from illuminating if brake fluid drops, increasing crash risk.) It's showing the same issues as above.

My vehicle stops working while in traffic when the auto stop is engaged. The abs, parking brake, and dash flashes prior to the engine stopping. I have been to the dealership multiple times and they are never able to recreate the issue. The check engine light codes produced are P0014 and c0800-03.

Service Power Steering, Drive with care warning comes on, vehicle looses all power steering. First time it happen was around November 2023. This will happen randomly, at various speeds, sometimes going straight, sometimes turning. Power steering will come back after a few minutes sometimes, a few times vehicle had to be turned off for a hour, but was out for over 3 days one time. During that incident we ran OBD scanner, C0800 code was showing for Power Steering Control Module, recommended repair was the replace battery, even though the battery was good. We went ahead and replaced the battery anyways, issue was not immediately resolved but after running the truck for an hour and then going…
