I am reporting a safety concern involving a 2019 Chevrolet Malibu. The vehicle was previously involved in accidents prior to my purchase and had known mechanical issues, including a gear shifting problem that was not properly repaired. In February 2024, while the vehicle was insured under Ocean Harbor Casualty Insurance Company, it sustained a significant front-end collision impacting the driver side. The impact was severe enough to cause structural damage, including a dent to the vehicle frame. Despite the severity of the collision, the airbags did not deploy at all. Based on the extent of the damage, airbag deployment would reasonably be expected. Prior to this incident, the vehicle had ongoing issues following repairs, including system errors and concerns that repairs may not have been properly completed by a certified facility. This raises concern that the airbag system may have been defective, improperly repaired, or compromised prior to the accident. I was not informed of any airbag or safety-related defects at the time of purchase from HGreg. I am submitting this complaint due to concerns of a potential safety defect involving failure of the airbag system during a serious collision.

The component that failed is the internal microswitch/sensor within the gear shifter assembly. The specific part that requires replacement is often documented in General Motors Technical Service Bulletin (TSB) 19-NA-206 or 23-NA-119. The faulty component is available for inspection if the dealership removes the old part and retains it. My safety and the safety of others are put at risk because the vehicle often fails to register that it is fully in "Park," which prevents the vehicle from shutting off properly, potentially leaving it in accessory mode. This could lead to a dead battery, leaving me stranded. More importantly, the failure to confirm the 'Park' state introduces a risk of the vehicle not being securely immobilized, creating a roll-away hazard if parked on an incline. The problem has been confirmed by local Chevrolet dealership service centers (receipts available). The issue is identical to the defect that prompted official safety recalls for numerous other GM models, including the 2017-2018 GMC Acadia. Furthermore, the symptoms described match those outlined in the active class-action settlement for 2016-2019 Malibu owners (STPLawsuit.com).

Shift to park issue. After putting the car into Park and attempting to shut off the vehicle, an alter to SHIFT TO PARK came up and the car could not be shut off. Vehicle stalls at lights and in traffic because of the START / STOP system GM has put in this 2019 Malibu. This is dangerous as the vehicle moves if on incline (sometimes backwards). There is no control. The vehicle then has to be shifted into PARK and then restarted

My vehicle fails to shut off when placed in Park. •It fails to start properly when the ignition is engaged. •It experiences shifting malfunctions that directly prevent safe operation. These issues are ongoing and remain unresolved despite being well-documented in GM Technical Service Bulletin 19-NA-206 and related bulletins, which identify the root cause as a defective shifter park switch and wiring harness.
