Lights Dim With Vehicle Running

CarComplaints.com Notes: The 2009 is starting to have the same problems as previous model years, including the headlights blowing out due to bad connectors.

The wiring harness connections aren't a big deal to replace, as long as your dealer or mechanic doesn't charge you an arm & a leg to "diagnose" the problem.

G6 Sedan 2.4L V4

  • Automatic transmission
  • 5,000 miles

I bought a brand new 2009 Pontiac G6, Automatic, 4 cylinder engine. Not long after I got it, I started noticing that when I had the car running, especially at night when the headlights were on, if I tried to put the windows up or push the brakes, the lights interior and exterior will all dim out. This also happens when the heater/AC fan is running. I took it to the dealership to have it looked at, and they told me that this was completely normal. Definitely doesn't sound normal to me. I could see if the car was not running and was sitting in the Accessory setting having this problem, because it'd be drawing the power from the battery. But, not when the car is actually running. Very frustrated.
