The contact stated that the front passenger's side front headlight was inoperable and replaced three years ago; however, the contact stated that the front driver's and passenger's side headlights have since become inoperable due to heavy condensation. The vehicle was taken to an independent mechanic where the vehicle was diagnosed with failed front driver's and passenger's headlights due to condensation.

Power train

9 reports1 crash1 fire
“MY 2013 BUICK REGAL VIN:[XXX] IS HAVING ONE OF THE 3 RECALL ISSUES THAT YOU HAVE LISTED. ISSUE #13V173, MY CAR WILL NOT START AND THE BATTERY IS LOSING POWER. I REPLACE THE BATTERY AND WAS INFORMED THAT THE BATTERY IS GOOD AS WELL AS THE ALTERNATOR BUT WHEN I TOOK MY CAR TO BUICK, I WAS TOLD IT WAS THE GENERAL CONTROL MODULE. UNFORTUNATELY, THE NHTSA DOES NOT HAVE MY VIN LISTED AS ONE OF THE AFFECTED 2013 REGAL MODELS BUT IN MY OPINION, IT SHOULD BE LISTED. I AM ATTACHING A SCREENSHOT OF THE PART AND REPAIR LISTED FOR MY VEHICLE. THE PART IS $929 TO REPLACE. PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).”

Engine

9 reports1 fire
“While driving the vehicle, I received an alert message on the instrument panel that stated “Remote Not Detected,” then the vehicle immediately shutdown in the middle of the road. I lost all power to the vehicle, I couldn’t put the vehicle in gear, neutral or anything to get it out of the road. I immediately replaced the key fob battery, no change vehicle didn’t start or power didn’t return. The vehicle had to be towed. After a couple hours power was restored and the vehicle started up again. I have replaced key fobs, had the dealership replace the car battery and the problem persists. This appears to be a defect, could you please advise on how to proceed with dealership?”

Had to slow down to 25 miles an hour because it was shaking so bad and limped it home. Last time they said it was a bearing in one of the tires. Also states said it has multiple misfires.

“AFTER USING THE BRAKE PEDAL, IT DOES NOT COME ALL THE WAY IN THE UP POSITION WHEN THE INTERIOR OF THE CAR IS HOT.
