2020 Chevrolet Malibu steering problems

Filed Nov 8, 2026 · Electrical, Engine · FL

i am filing a formal safety complaint regarding my 2020 chevrolet malibu. my vehicle recently displayed a “service ESC” warning along with a flashing check engine light. these warnings appeared unexpectedly and have raised serious concerns about the safety and reliability of my vehicle. the electronic stability control system is an important safety feature, and a flashing check engine light may indicate a serious engine malfunction. i am concerned about the possibility of experiencing reduced engine performance, loss of power, or compromised vehicle control while driving. i am also aware of reports from other chevrolet malibu owners describing similar warning messages and electrical or performance-related problems. i believe these issues warrant investigation to determine whether there is a recurring manufacturing defect affecting these vehicles. i am requesting that the federal safety agency investigate these safety concerns and determine whether a recall is necessary

The contact owns a 2020 Chevrolet Malibu. The contact stated that the message "Steering Assist Reduced - Drive with Care" was intermittently displayed on the instrument panel while driving. The contact stated that excessive force was needed to turn the steering wheel. In addition, the message "Service ESC" was displayed, and the steering failure became more frequent. The vehicle was taken to an independent mechanic, where the contact was provided with an estimate for a diagnostic test. The contact declined the diagnostic test.

My 2020 Chevrolet Malibu experienced a sudden and severe electrical failure after driving through normal roadway water. Immediately afterward, the vehicle displayed multiple safety‑critical warnings including loss of power steering assist, Electronic Stability Control (ESC) faults, brake control faults, and reduced propulsion. A GM dealership inspected the vehicle, scanned the modules, and found more than a dozen network and chassis‑related diagnostic trouble codes, including: B3979, U0164, B1325, B3122, U0121, C0196, C0460, B1011, B097B, B3205, C056E, C056D, U0420, U1510, C0545, U0422. These codes indicate failures in the steering system, brake control module, stability control system, body control module, and multiple CAN‑bus communication networks. The dealership confirmed: – No physical damage – No evidence of collision or impact – No evidence of flood damage – The suspected failed component is the electric power steering rack (GM part 85621696) – The part is not available, meaning the vehicle cannot be repaired – I would be responsible for diagnostic and repair costs This is a major safety concern. The vehicle can lose steering assist, stability control, and braking support without warning. The inability to obtain the required steering component makes the vehicle unrepairable and unsafe to operate. I am reporting this because this appears to be a systemic electrical/network failure affecting critical safety systems. I believe this defect poses a significant risk to drivers, passengers, and other motorists.

So while I was driving my car going 60 on the highway it seemed to be having electrical issues all the lights on my dash popped on then popped off and only a few lights actually stayed on I can't remember exactly but the check engine and my abs stayed on and then on my screen it read to me warning power steering fault my headlights were dimming on and off like my car was going to die, so I had to pull over for my safety and other drivers safety, so after I pulled over safely I shut my car completely off and waited about 5 minutes and turned it back on when it turned back on the only light that popped on my dash was the check engine light, but the check engine light had actually been on the dash for a while after I replaced the 21 fuses that were missing that I didn't know were missing when I purchased the vehicle as is from a dealership the only thing that made me decide to check my fuses was because my check engine light was popping on and off and would stay off for a while then come back on a code reader said it was something to do with my turbo that code it was just very odd and the car was shifting weird 3 or 4 months after the purchase date XXX also after I put all the fuses back in a ton of codes popped up others safety and mine were at risk as I didn't really have control of my vehicle when it was doing that and it started breaking itself when I wasn't even hitting the break it was like jolting it's self and stopping slightly. I took my car to AAMCO Total car Care for a free diagnostic test, and then I had recently took my car to a Chevy dealership in Nampa Idaho off garrity boulevard because online it had told me there was recalls for my car and that recall was exactly what I was thinking had started off as the original problem originally leading into the other problems I got told to bring my car in then the fed me information saying pretty much it was a bust and that specific Malibu has no recall I think they just didn't want to work on it

While driving the cars speedometer and all gages will stop working, or they will constantly move up and down on their own, it will also not accelerate to speed limit in a timely manner.. when stopping the car it will brake extremely hard on its own and throw me forward it will also give a warning message on the dash that the power steering isn’t working and to drive with caution. When parking the car and it is in park a message on the dash will appear saying shift to park.

Electrical issue , Continuously losing communication to EBCM causing the car to go haywire with warning lamps on the dash board and then it brakes on its own , while driving on the highway at high speeds. This is very scary and extremely dangerous and this could eventually cause a serious accident. This has been occurring for 3 months now. I’ve had the car serviced 3 times within the last 3 months , costing me a lot of money but with no real resolution. Problem has been confirmed by independent Mechanics , they stated the codes are a loss of communication to all control modules , they then reset / reprogram modules , which is only a temporary fix because it always happens again.

The steering assist is reduced will come on. The car randomly turns itself off and back on when at a stoplight; this has happened four times now. I worry that it will shut off and not restart creating a hazard on the road.
