NHTSA Complaint #11704338 — 2019 CHEVROLET MALIBU

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).
