Problems with 2001 Chevrolet Tahoe EXTERIOR LIGHTING

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. *tr

The low beam headlights stop working when in use.

Our 2001 tahoe has had problems with the drivers side lower light assembly for quite a while. it houses the turn signal, clearance light and daytime running light. it constantly fills with water. there are no cracks in the lens and i have dried it out and replaced bulbs on a monthly basis. i noticed that a large majority of chevy trucks, tahoes and suburbans on the road have one of these lights out also, one side or the other. *nm

Defects: abs light on at 43,600 miles. when car is turned off a loud noise is heard beneath the drivers side of the vehicle my independent mechanic said the abs unit is purging. at 20 miles and regularly there after, when the fog light power button is pressed, the rear window wiper briefly makes noise as if it had been activated. at 3000 miles and regularly there after , all four doors squeak at the hinges and must be lubricated weekly. at 10,600 miles the rear differential began to leak. both driver and passenger seat squeak and do not firmly lock into position. the driver and front passenger seats do not lock into position. the parking brake has not worked since i purchased the vehicle. *la

I pushed the override button on the dash looking for the fog lights in luther, michigan at 5:00 am. all the lights went out - i panicked and pushed the button repeatedly until the lights came back on. this has happened on numerous occasions. i could have been killed.*ak

Doors are not equipped with door ajar warning chime. dealer / manufacturer notified, and informed consumer that those vehicles were not manufactured with that equipment. *ak *slc
