“Driver smelled smoke shortly after starting his vehicle and driving away from his home. The smell was of plastic, and it was assumed from an electrical short/fire. The driver stopped the car and inspected the engine area. No evidence of fire, however the driver turned back and drove the vehicle home. Strong burning plastic smell again as the vehicle was stopped. The cabin was filling with smoke. Driver opened the trunk as the battery was located in the right rear section of the trunk.

“Dt: the contact stated a gallon of milk spilled into the driver's seat. The milk spilled underneath the seat. When this happened it shorted out the electrical module that operated the dashboard lights and headlights. As a result the lights were blinking in and out. Currently, the vehicle is at a certified dealership for repairs. Updated 12/27/2005 - the tire pressure monitoring light illuminated on the dash. The dealer replaced the module. The trunk would not close properly.”
