There is a problem with the fuse box located in the trunk. My car has completely lost engine power while driving on multiple occasions. Fuel pump, alternator, and battery have needed replaced. There is a short in or near this rear fuse box. Fuel pump relay has been replaced, and connections greased. Temporarily fixed, then a few days later shuts off while running. From researching, this appears to be extremely common with this model across multiple years, with the wire leading to the fuel pump relay burning up and shorting. Clearly poor wiring. At least three times my car has completely shut down while in motion with no warning at all. Multiple crank/no start situations as well. My next option is to replace the entire fuse block, but that will not fix wiring design. Have been towed multiple times in a short period of time.
Owner was driving car was informed that tail lights were not working by another motorist. Stopped at shop. Repair shop unplugged light harness and customer left then approximately 20 mins. Later smoke and fire was noticed coming out of the left rear trunk area at location of wiring harness area. This is the second wiring harness trunk fire this investigator has investigated on a chevy Malibu in the last 6 months. A second fire was investigated with the same scenario on a 2006 chevy Malibu that occurred on 8-11-2014.
