2007 Chevrolet Impala electrical system problems

“I started for the first time in early June of having reduced engine power. At this time I get several warrning lights on dashboard. I get engine power is reduced, traction control and engine light. The car goes into limp mode. I replaced the accelerator pedal position sensor after the first event. Since this time I had it happen 4 more times. This situation can be dangerous if a car is behind me and I slow up real quick due to going into limp mode. I try to pull over where I can when this happens. Once I pull over for 10 minutes the car will resume like normal driving with just the engine light on. The next day the engine light usually leaves. It is hard to know when this will occur but it can be a dangerous situation to be in.”

“There is an electrical connector behind the right side, kick panel that overloads and chars the plastic housing. The connector is for the rear defroster grid, but it cannot handle the amperage that the grid carries. It overloads and is a fire hazard that can could start a fire in the passenger compartment. It is a very common problem on ninth generation Chevrolet Impalas, to the point there are multiple YouTube videos, offering shade tree repair advice that bypass the connector with a jumper wire. I’m including a link to one such a video. [XXX]”
