NHTSA Complaint #11484701 — 2012 BUICK REGAL

Car lost all electrical power while driving (moving) and fully shut down, stalling immediately. Nothing electrical worked, including 4 way flashers. The alternator was just replaced 2 weeks after this same full loss of electrical power was diagnosed when going to start the car while parked. The battery was fully recharged at the repair shop and deemed ok. I had my road service come out to address the issue. Before they arrived, I was able to restart the car. The service tech checked the battery and alternator. Both checked ok, but the battery was almost drained and did not show signs of any dead cells, despite it having been able to restart the car shortly before the road service arrived. We replaced the battery. Car is in the shop now. The safety risk is full loss of power while moving resulting in no brake lights, 4 way emergency lights, full stall, loss of power steering and brakes that can lead to a collision on the highway. This type of problem has been reported on numerous Regals
