2020 Chevrolet Malibu Steering Problems

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. The attached photo is a is a picture of the printout the Chevrolet dealership Service Manager provided to me.

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

What component or system failed or malfunctioned, and is it available for inspection upon request? Car had numerous times of completely turning off mid drive and was taken into a certified dealer for inspection, with a conclusion that nothing was wrong. The transmission has failed (03/22/24) and has been recently replaced upon diagnostics from certified dealer. 2 days later after receiving vehicle from transmission fix (04/20/2024) the vehicle began to experience Electronic Stability Control errors and caused steering assist to also fail mid drive and cause a locked steering wheel. These errors occurred (04/22/2024 and 04/23/2024) How was your safety or the safety of others put at risk? All of these factors explained above have happened during a drive and has put me at risk of numerous accidents that could have been fatal. The most recent one dated above, happened in the middle of the road with little to no where to safely pull over and restart the car system. Again, could have resulted in a fatal accident. Has the problem been reproduced or confirmed by a dealer or independent service center? Electronic errors of the vehicle shutting off was unable to be reproduced or confirmed by dealer. Transmission failure has been confirmed and replace. ESC and steering assist has yet to be confirmed from dealer. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? This vehicle has been inspected by numerous dealers and or auto shops with little to no help in fixing any problems. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? I also have warning lights from all times I have experienced failures or warnings from the vehicle and will be providing this.

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.

Since last year I am having this problem in this car, even after parking the car, it is giving an error of "shift to park', I have already taken it to the car dealership twice to fix this problem and still the problem is not getting fixed in the car. Not even that I live in California and while coming back from Vegas last year, this car suddenly stopped working while on the freeway, luckily I was near truck station so I stopped the car. This is a new car and I didn't even drive 36000 miles on it and it is giving me problems. This car is a serious problem and I would request nhtsa to please step in and take action regarding the manufacturers.

I bought a 2020 Chevrolet Malibu LT on April 26, 2023 from Lake Hartwell Chevrolet in Toccoa Ga. It drove fine for 3 days. Then a chirping started in the steering wheel. On May 3rd. While I was taking my wife to our baby doctors visit, as I turned into the parking lot, the engine light came on, and the steering failed. I was able to safely get it into the parking lot and out of the way of the other cars. I called the dealership and they had it towed to their shop. They charged the battery saying that's all that was wrong with it. However, as the clean up guy at the shop was bringing it to me, the engine light came on again and he took it back to the shop. Within the next 14 days from then, they replaced the steering module, battery terminals, which seemed burnt, they said, and realigned it. However, all of this is word of mouth as I was not given any paperwork verifying this repair. The next day, the chirp returned. It has very loose steering and sways easily from side to side. Also, upon a diagnostic check by another certified mechanic, the computer would not link and give codes. He told me one of the computers in the car was bad, but not sure which one. I checked and I can not qualify for the lemon law, so I contacted the general manager and said I wanted to return the car and my bank returned their money. Or, another chevrolet car, from Chevrolet, not from this lot. This car is unsafe for me and my family. He said that was not possible as the tag and title has been processed. So I am ready to pursue legal action. The cars they let me drive during my cars repair were junky, too. One wouldn't drive over 30mph and the other had a ticking motor. I feel this business presents a danger to anyone who in need of and buys a car from them. Date of ownership: April 26, '23-present. Today is May 24,'23. They have also failed to give me the paperwork verifying the Chevrolet Lifetime Warranty on the Powertrain and Transmission. That was promised on the day of sale.

This is an intermittent issue and hard to reproduce on demand. I have evidence in the form of multiple videos that may be provided anytime. Videos can be found here: https://www.dropbox.com/sh/zubc5ilgahayvxa/AABf3M1mLBikxQswv17Yn-YQa?dl=0 In the middle of driving on freeways, highways, or regular roads, the car will quickly slow down to a very low speed, around 5 mph causing other drivers to have to quickly swerve out of the way before wrecking into me. The power steering will also intermittently fail, as it becomes difficult to turn the wheel during these times. The car will also not accelerate at my will like it should at this time. Check engine lights will show up, as well as other warning notifications on the dash board. Some of the warnings include "Service Power Steering. Drive with Care", "Fuel Level Low", and "Service ESC". The car will also intermittently show all gauges in the zero/off/empty position. The car will also say "Shift to Park" when trying to turn it on, even though it is already in shift. I have sent the car back to the dealer 5 times to date and am about to pick it up again today as they have called me and said "it's ready" again. Each time they take the car, they do not address the issue. The first time I took it in, they just performed a recall repair for the camera and suggested the problem may be fixed from that. They claim they cannot fix something they cannot reproduce but I suspect they do not want to spend the time/hours/money it will take to figure out the problem since it is still under factory bumper-to-bumper warranty. It is still under factory bumper-to-bumper warranty but Monument Chevrolet in Pasadena TX refuses to repair anything and claim there is no evidence of the problem even though I've emailed them multiple videos of the problems happening. Auto Nation in Houston TX is who has the car now. It was recommended to me by General Motors to try another dealer. This is where I'm at currently with the situation.

The vehicle will randomly shut off while driving. All warning lights light up on the dash and notification of "reduced steering" pops up. Taken to the dealership and has been there for 19 business days. They will fix a component, I have picked it up twice and it has shut off before I could even get home forcing me to tow it back. This last time they were bringing the car around and it shut off in their own parking lot before they could even give me the keys. Every time they run diagnostics it's a new code. Vehicle is unsafe to drive due to shut-off and loss of steering.
