NHTSA Complaint #11702031 — 2017 CHRYSLER PACIFICA

My 2017 Chrysler Pacifica Touring-L has suffered repeated and dangerous electrical failures since purchase. Shortly after buying it from AutoNation Chrysler Dodge Jeep RAM in Valencia, CA, I had to return it twice for electrical repairs that kept it in service several weeks under warranty. About two years later, while still under extended warranty, the engine underwent a complete rebuild for multiple-cylinder misfire codes that were likely caused by intermittent CAN-bus voltage loss rather than a mechanical defect. Over the past nine months, the vehicle has again developed severe electrical faults while driving: sudden loss of power steering assist, all dashboard lights illuminating, windshield wipers activating spontaneously, and the engine failing to shut off using the Start/Stop button. The vehicle has also stalled without warning while driving in traffic or idling at red lights, restarting only after 5–10 minutes and blocking traffic lanes, placing me and surrounding drivers at significant risk. Two major repairs in the last two weeks failed to resolve the defects: (1) repair of the CAN-bus system after the vehicle would not start and acted erratically while driving, and a week later (2) replacement of the brake-booster vacuum pump, which was shorted internally and caused CAN-bus shutdown, complete steering loss, sudden braking, and no engine power. The vehicle is currently at Dependable Chrysler Dodge Jeep Ram, Canoga Park, CA, awaiting further diagnosis despite repeated repair attempts. These symptoms match Chrysler TSBs 08-007-17 and 08-033-21 concerning Body Control Module water intrusion and communication faults. This ongoing electrical defect has caused steering loss, random stalling, ignition failure, and unpredictable vehicle behavior—issues widely reported by Pacifica owners. It poses a serious safety hazard and warrants immediate investigation and recall.
