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. These aftermarket components are the direct cause of system failures involving engine management systems, lights, and numerous electrical failures. I sincerely request immediate and thorough investigation which I remain confident will result in massive recalls of these inferior products.

My blinkers started blinking real fast and I couldn't figure out why. I asked my brother and he told me I had a light out somewhere, so he helped me locate it. It was my blinker on the driver side back. I replaced it and a few months later it happened again. I replaced it again. All this happened in 2013. In the summer of 2014 it happened again with the same light. I replaced it again. I was watching good morning America this morning and seen where they were investigating safe cars at used car dealers. It gave a web site to look and see if your vehicle has any recalls. I looked and it showed mine had 4. I called the number it gave and the lady told me mine had none with the VIN # I gave her. Why then am I having problems with this one light?

11/18/2009: Smoke was coming from the steering column. Spoke with a family member who works as a technician for pep boys. He believed the cause to be the multifunction switch. 11/20/2009: Brake lights would not turn off even when the vehicle was turned off. They stayed on until they completely drained my battery. Looked up recalls and found there was a recall on the multifunction switch: NHTSA action number: RQ08001. 11/21/2009: Called the GM number listed on the NHTSA recall form to ask for assistance with the cost of replacing the part. Was refused assistance and given the following reasons: My particular VIN was not one included in the recall. I didn't purchase my vehicle from a GM dealer. I purchased my vehicle used (there was only one previous owner). My vehicle has over 100,000 miles on it. I don't have a (proven) history of being a loyal GM owner. I don't have my repairs done at a GM dealer. The estimated cost of the multifunction switch itself is $200. That does not include labor. The repair needs to be done immediately as the vehicle is unable to be driven as is.

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. This part was replaced with another bad part that failed like the first original part. They should be required to replace the defective part with a reliable new design or be required to replace it again if it fails again.

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. If this issue is unrelated to the 01073 recall, I am willing to pay for repairs out of my pocket, but I want Chevy to initiate the diagnosis, instead they are telling me that they will provide no financial support whatsoever to even determine the cause of this error. I have stressed the importance of operating a vehicle with all safety features intact, and it is obvious that the same problem that 01073 addressed has recurred. I would like Chevy to bear the costs of diagnosis, and costs of parts and labor for all repairs required to remedy the malfunctions relating to the hazard switch and/or mfc (multi-function turn signal switch).
