The wiring to the head lambs (both) are burning up, causing a burnt smell in the car, company says to buy new head lamps. The electric wire system in the car has been a problem since the beginning. Evidently the heat in the motor area is to much for the quality of the wiring covers and they cause lamp burn out,and burn the plastic wire covering. Car is used for pleasure has very few miles. Very hard to take a picture , tech had a hard time getting to it.
Second warning regarding the electrical wiring regarding the front head lamps. The wiring is burning up and it will cause a fire with deadly consequences. This car has had a recall before regarding the wiring of the back stop lights, if nothing is done there will be a fire. The seat (front) covering is peeling off, CO. Says its normal. This is my 2nd report and the smoke is getting heavier all the time and it is affecting the computer of the car function. The vehicle is always picking up children with my wife. Very difficult to get photo, but is visible on both sides of the front head lights. There has been no fire yet but there is smoke.

2 years ago manager told me the wiring of the head lamps was melting but he can only replace the whole unit( both). I told him that a car with 30000 mils this should not be happening. Nothing he can do. The car has started to burn on the inside , smoke comes out of the engine. Car transports children. To and from school. Eery other onth lamps burn out, happening since the car was new. Finally went to shop again today and they put it on paper. Wire coating falling apart, causes burn out of lamps. This is a huge danger and should be recalled not paid by user. Have sent 2 other complaints to NHTSA with no resolution. Why????? additionally car has had tail lamp problems since the beginning with one recall. Additionally the seat cover of the driver side is coming apart in pieces since year 2. How is it possible no action has been taken?.
