I was driving down the street when smoke began to come from beneath the hood and into the vehicle. I pulled over and opened the hood and saw flames coming out from underneath the battery compartment. After extinguishing the fire the car no longer started. Upon inspection all of the electrical wiring had melted.

- If one of the headlamp wiper arms becomes misaligned, the wiper balde can lodge in the groove under the headlamp. If the washers are activated with the wiper blade in the misaligned and lodged position, the washer pump will run continuously expelling all available fluid.
- Risk
- Pump operation in the absence of fluid can cause the pump to overheat and cause a vehicle fire.
- Remedy
- Dealers will replace the headlamp washer pump on these vehicles.

Failures of goodyear aquatred tires.*mr while on a trip the tread of the left rear tire came loose from the steel cord. This caused a wobble while driving. The next day the front right tire blewout at the sidewall.
While driving on highway, I slowed to turn off highway. After completing turn tried to accelerate but engine would not accelerate. Was able to move the car off roadway at idle RPM only. Car towed to local shop. A plastic piece on the end of the accelerator cable had disintegrated causing the accelerator cable to become disconnected from the engine throttle lever. This is the second time this failure has occurred. The plastic piece should have been made of metal. What if I had been in the middle lane of a six lane highway when this failure occurred?
