I stopped at a traffic light and was hit in the rear by the vehicle behind, driving my vehicle into the vehicle in front of me. I was given a traffic ticket and my vehicle sustained damage to front and rear. The driver behind me stated that my vehicle did not have brake lights. Which was confirmed by the officer. The diagnosis by the dealership was that the multifunction switch in the steering column was broken. This was done on nov. 10, 2009 as I have been unable to get the vehicle there due to legal problems. I did however call GM soon after the incident and try to resolve the problem at that time . The Chevy dealership contacted GM for possible repair. It was noted by the dealership that the switch was replaced under recall in 2002. The GM customer service reps are trying to deny repairing again saying that they are not responsible twice. …

Vehicle is exhibiting problems with brake lights and hazard flashers, consistent with recall 01073. These issued have been intermittent, but in the past month have become constant. Chevrolet customer service has stated that this recall service was performed in 2002. This issue with lights has occurred since 2007, contact with Chevy has been off and on since that point. Contacted Chevy today 9/15/2008 because multi-function switch has now started to smoke when turn signals are used. This is obviously coming from the mfc which was supposedly repaired in 2002. Chevy has stated that recalls are a one-time fix and any further issues at any point is the liability of the customer. They are unwilling to provide any support for a resolution of a recall repair with was performed only 6 years ago. …

My customer complained of a transmission failure involving, but not limited to a DTC p0785. I asked my customer if the involved vehicle (2000 Chevrolet Blazer) had any dealer or after market accessories installed, customer adamantly replied: no, "bone stock GM." my customer was not aware that the involved vehicle had a theft deterrent system, manufactured by "karr" and distributed by audiovox with installers nationwide. I have been actively involved with GM dealerships for over forty years and possess a wealth of experience in parts and service experience. I removed the suspect security system and repaired the damaged wiring which resulted in the improper installation. In the past week I have been confronted with four customer complaints which resulted from security systems, aftermarket radios and including aftermarket headlamps. …

Dt: three years ago the problem began. The owner pulled over to the side of the street and when the hazard lights were turned off then brakes went off as well and would not come back on. The main tail lights and brake lights did not work anymore. There was a recall and the owner did not receive the recall notice. The vehicle was taken to the dealer for service and the hazard light switch was replaced. The next time the hazard lights were used, the brake lights stopped working again. This happened about ten months after the first failure. Then the vehicle was taken back to the dealer, they were willing to repair the hazard lights at a cost of $500. There seemed to be no indication from the dealership as to why these hazards lights kept failing. The dealership has been contacted by the owner at least 7 times in last month and a half. …

The turn signal in the vehicle began clicking even when the switch was in the neutral (off) position several months ago, however, the turn signals appeared to work properly. A couple weeks ago, while sitting at a left turn light with the turn signal on, a white stream of smoke began coming out of the steering column in the vicinity of the turn signal level. I turned off the level, and the smoke stopped. No corrective action has been taken yet, but I am afraid a fire May start in the vehicle from this. It appears there is a service bulletin (# 01073) related to NHTSA item # 636517 that May be related or the same, but the dealer says no recall is open and will only charge to replace the part(s). This seems like a safety/fire related issue and I have read numerous cases online where other owners experience the constant clicking noise from the turn signal too.
