The tail light wiring harness in the cargo area is not protected very well. As a result it may become damaged due to normal wear a tear. This damage can causing some or all of the rear lights to stop working.

Various electrical components under the front carpet/rubber mat may become damaged if excess water is used to clean the rear cargo area.

It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

On vehicles equipped with a left side cargo door, water and road contaminants may become trapped in the protective conduit that covers the fuel filler pipe, which can cause the pipe to corrode. Significant corrosion may allow fuel to leak during refueling, and in the presence of an ignition source, this could cause a fire. Dealers will install a new fuel filler neck to correct this concern. The General Motors recall number is 12166.
