Three problems related to underhood wiring have been reported for the 1996 Buick Regal. The most recently reported issues are listed below.
When at a stop and without warning vehicle caught fire under the hood.
Burning smell, and smoke comes from under the hood of the car when ever the heat is being used. Or I have traveled over 50 miles. A rattling sound comes from the steering wheel or steering column when ever I make a turn. The sun roof just hums when ever the switch is pushed to open or close it, it doesn't work at all. (cannot open sun roof).
Harness assembly replaced.
