I was told the bcm on my vehicle is bad. It cause my car to go all out of wack. Multiple warning lights come on (ESC, ABS, power steering, check engine), the gauge controls flutter, my gear shift clicks on and off, the car has even shut down on me in the middle of traffic, wouldn’t start, wouldn’t shift, basically wouldn’t move at all even when it did start. How would a bcm shut down my whole vehicle?

While driving my 2022 Chevrolet Malibu on the freeway, I experienced a loss of braking. This created a serious safety hazard because I was unable to stop the vehicle normally. The vehicle had previously displayed a check-engine warning. I brought the vehicle to the Chevrolet dealer. The dealer is requesting approximately 4,000 for repairs and has refused to perform the turbo-related recall/special coverage repair unless I pay for those repairs. I am requesting that NHTSA review this incident as a potential vehicle safety defect and review whether the braking problem may be related to the known turbo/engine issue Break vacuum pump is broken and diagnose by the dealer . Check engine light was on prior to incident due from Turbo charger failure

Component: Air Conditioning – A/C Hose Assembly / Refrigerant Discharge Line The air conditioning refrigerant discharge line (A/C hose assembly) appears to have been improperly designed and/or installed during manufacturing. The rubber A/C hose was routed in a manner that caused it to rest against or press against the side of the engine. Over time, the engine heat and constant contact burned a hole through the hose, causing a rapid loss of refrigerant (Freon). As a result of the refrigerant leak, the air conditioning system stopped blowing cold air, and the HVAC system no longer functioned properly. This failure was not caused by normal wear and tear, but by the improper routing and placement of the A/C hose against the engine. The issue was confirmed by Meineke Service Center through a diagnostic inspection and UV dye leak test, which identified the damaged refrigerant discharge line as the source of the leak. A significant safety concern is that simply replacing the hose does not permanently correct the problem if the replacement hose is routed in the same location. Without a manufacturer-provided redesign or long-term repair solution that prevents the hose from contacting the engine, the replacement part is at risk of failing in the same manner. There were no warning lights, dashboard messages, or other indications before the failure occurred. The air conditioning stopped blowing cold air after the refrigerant escaped through the damaged hose. I believe this is a manufacturing and/or design defect that could affect other vehicles with the same hose routing configuration. I am requesting that NHTSA investigate this issue and determine whether a safety recall or manufacturer corrective action is warranted.
