Two problems related to trunk wiring have been reported for the 2010 Chevrolet Impala. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2010 Chevrolet Impala based on all problems reported for the 2010 Impala.
The contact owns a 2010 Chevrolet Impala. The contact stated that the trunk locked and was unable to be opened. When the failure occurred, the turn signals also failed. The vehicle was taken to the dealer who stated that the 12 volt relay to the trunk release needed to be replaced. The contact stated that the rear seat would not go down and there was no key entry for the trunk. The vehicle was repaired. The failure mileage was 90,000.
The rear defroster stopped working. After investigating the issue I discover the electrical harness connectors holding the wiring for the rear defroster(and all other wires) is burnt. , the electrical connectors are harnesses for wiring leading form the engine area, to the rear of the vehicle for all electrical components, including the rear defroster. Visibly you can see the area that is burnt for the rear defroster. The wiring for the rear defroster is not fused, and in my opinion is a fire hazard. While doing research on this issue I discover that other owners have had these issues, and is very prominent in Impala's between 2006 and up. With out a fuse for the rear defroster there is no safety mechanism preventing a short, or burn out of the components, thus creating the potential for a fire inside the compartment of the vehicle, and the rear defrost not to work.
