2008 Pontiac Grand Prix electrical complaints
Page 3 of 3: complaints 41 to 43 of 43, newest first, as owners wrote them.
I bought this car used with low mileage, around 30,000 miles in november 2008. My headlights are not working on dim. They work fine on bright. Seems like this could be an electrical problem or a short, because the dims work at times and then will go off if you hit a bump. This has happened several times since I bought the car. Warranty ran out so I took it to an individual mechanic who replaced the dimmer switch. That didn't fix the problem. I also had to replace the power steering pump within the first year or two of purchasing this car.
