Wiring problems of the 2001 Chevrolet Tahoe

My passenger seat cot on fire. My truck was parked in the mall parking lot as my self husband and two children came out from shopping to my the car I opened my passanger door I got in and adjusted my passanger seat for comfort and my husband was getting the gift and kids in the truck and then all of a sudden I smelled smoke. I got out of the car and I started to look where the smell was coming from and looked under my passenger seat and there was sparks coming from under the seat there was a black box under the seat that was sparking I called 911 and the fire department came and put the fire out my whole passanger side burned and the fire department said it was the motor box under the seat that cot fire bad electrical wiring he said. The car was parked and we had not started it the only thing I did was adjust my seat and as I was waiting for my husband to get in and kids tho get buckled I smelt something burning and my set got hot. I can't believe this happened.

Noticed that the headlights became intermittent; started occurring more frequently once problem started eventually headlights would not stay on; discovered the problem was relative to the position of the tilt of steering column; vehicle was evaluated and repaired; repair included replacing the wiring harness and the multifunction switch; the wiring harness had shorted out apparently from the repeated movement of the tilt being adjusted; old part is available; I'm reporting this because the problem is dangerous when the headlights go off traveling at high speeds at night. It is also a fire hazard per the mechanic that repaired the vehicle. We did smell smoke at one time but didn't notice any other components damaged. Maybe we were just lucky.

My complaint has to do with the running lights and the brake system for the 2001 chevy Tahoe. I have had my running lights replace numerous times and there is an apparent short in the wiring connection that will have to be fixed. My parking and abs brake lights keep coming on even though the braking system has been replaced and the lines have been flushed. These lights go off once the car is restarted, but sometimes come back on. This will be my second trip to the mechanic to see what the problem with my brakes is. I think this is ridiculous because I have already spent several hundred dollars that I didn't have, in order to ensure my children's safety. Now after reading about the parking brake, who knows how much more I will have to spend to have it checked to see if that is the problem? since there are parking brake issues, the vehicles should have been recalled at the cost of the company, not the consumer.

While driving passenger in the rear seat adjusted the passenger seat and noticed sparks coming from under the seat. Later, the sparks turned into flames. The fire department extinguished the fire because the wires kept igniting.
