What owners say about the electrical system

Verbatim from NHTSA complaints, newest first
“The contact owns a 2013 Buick Regal. The contact stated that while stopped at a stop light and depressing the brake pedal, the hybrid battery would power off as intended; however, when the brake pedal was released, the vehicle would lose automotive power before suddenly independently powering on before jolting. The check engine light illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. In addition, the contact related the failure to NHTSA Campaign: 13V173000 (Electrical System); however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 130,000.”

“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?”

“There is condensation and moisture present inside the high definition front headlight assemblies, which causes the headlight illumination to be diminished and created a visibility hazard while driving at night. The vehicle was taken to the Ganley Chevrolet dealership who diagnosed that the front headlight assemblies were faulty and needed to be replaced. The cost to replace both is about $3,000. Then I went to Damper's Automotive of Cleveland Ohio for a second opinion and after replacing the bulb in the passenger side headlight, the bulb immediately blew. Based on complaints from other customers this is a known issue on low and high mileage vehicles of the same make and model. It's a astronomical cost to replace these assemblies and they could go out at any time while driving due to the trapped moisture and-or electrical wiring exposed behind the headlight.”

“Left Headlamp Assembly and Driver’s Window Regulator were replaced under Warranty and now need replacing again! Trim Strips were replaced under Warranty because they were rusting and now they are all rusty again! Electrical System now blows fuses. 2103 Buick Regal Turbo just reached 60,000 miles. HOW MANY TIMES WILL I HAVE TO SPEND $2,000 TO FIX THE FAULTY LEFT HEADLAMP ASSEMBLY WHICH WAS GOING ON IN 2011 & 2012? There’s Complaints all over online!!!! I haven’t been able to go out at night for 6 months because of no front headlight!!!!! I have been to 3 Buick Dealers and they all have no idea how long this $2K light assembly will last because it should have been recalled!!! The lastest Buick Dealer was trying to steal my vehicle by saying the “Check Engine” light indicated that I am going to have all kinds of problems with my turbo or engine (he wasn’t sure what it was) and that my car was not worth keeping!!! I should get a new car! I asked him how much to take care of the engine problems and he said $3,500. So with the supposed engine problem & headlamp, that’s $5K. I SHOULD BUY A NEW CAR PER DIXIE BUICK IN FORT MYERS, FL!! The other Dealerships said it was…”
