Invalid Data Received From Body Control Module

I own a 2022 Chevrolet Silverado LTZ Texas Edition with 51,000 miles, equipped with the factory multi-camera system and rear backup camera. The camera images are clear and all cameras function normally, but the forward/reverse guide/trajectory lines no longer appear. When the cameras are activated, a blue hourglass appears in the upper-left corner and the guide lines never load. This is a safety concern because the guide lines help the driver judge the vehicle's path and distance when backing up and maneuvering in tight areas. The loss of this feature reduces the functionality of the factory safety/parking camera system. I took the truck to an authorized GM dealer. They diagnosed a front…

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…

Multiple electronic/body-control systems fail intermittently, confirmed by dealer diagnostics (DTC summary report, 5+ service visits): Active Lane Management/Blind Spot system shows "blind spot alert unavailable" and lane-keep faults, mainly during turns and lane crossings (DTC U0422-00, "Implausible Data Received From Body Control Module," stored across ACC, LBSS, RBSS modules). Rear camera intermittently fails to display (DTC B217A-87 "Rear Camera-Missing Message," B217A-9A "Rear Camera-Component or System Operating Conditions"). 4WD system shows "Service 4WD System" warning during sustained highway driving over 60 mph, clearing after 1-2 minutes. USB port intermittently shows "USB…

Vehicle check Engine light on, showing "Reduced Engine Power." Vehicle still able to be driven, but will not accelerate with any proper pace or power. Cannot get above 3000 RPM without losing power, has put me in two dangerous situations in the last two days that almost made me lose my life. On highway, trying to accelerate to match traffic speeds, lose power and had to dive to the emergency lane to not get plowed by a truck. Today, was city driving, at a red light, could not accelerate and had to dive to a crawl the vehicle into a turn lane where I ended up sitting for about 10 minutes till the engine offered enough power to keep driving. By all information I can find online, it seems it is…

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…

Driving on the highway I lost braking power the brake vacuum pump ceased up and broke the bolt in the cam shaft that had to be drilled out and replaced then that caused more damage to the cam and bottom end of the motor for the motor to throw the following codes: p0365 p0369 p0012 p0299 b1215 p0234 U3008 U3003 U0300 p1594 U0140 U0154 U2300 U0422 B1B36 With all these codes I did the following and am now without a vehicle thanks to FORD. This vehicle only has 58000 Miles is single owner and was well maintained till this incident now I am told the motor has to be rebuilt as the cam and bottom end are the issues with this vehicle and this has happened to a lot of people and could have cause a…

After heavy rain or a carwash, the door locks and lift gate don't work from key fob. And the vehicle says no remote detected and has trouble starting. After a day or two they start working again. It caused U0422 (invalid data received from body control module). On forums it says it can be water leaking into the vehicle and shorting out the BMC from either the HVAC drain or a weatherstrip somewhere. Now my rear passenger door locks don't work at all. Dealer wants to replace the actuators but can't find the root cause of the problem. Issue has been going on for over a year now.

After leaving my truck parked for a couple of hours over dinner I returned to find error messages stating "Service Power Steering / Drive With Care" and "Service ESC". I also received a notification from OnStar stating "Diagnostic Alert: Service the Antilock Braking System in your 2022 Sierra within 1 day." My power steering was non-functional, nor were any cruise control functions. Repeated stop / start cycles did not clear the errors or regain functionality. After parking overnight everything was functional, and the errors on the DIC were gone. Using a code scanner there were historical codes of U0131 and U0422.
