Since having the heater / ac fan speed control module replaced under a recall last fall, this summer I have had several situations where the A/C unit will turn to heat or, the A/C will go to defrost, defrost / feet, without moving the selector controls.

This vehicle is a duramax 2500 (diesel), the first thing that happened was the engine hours reset itself to zero the dealer said it needed a new instrument cluster then the gear shift indicator quit working so you have to count each time you move it to know what gear you are in I feel this presents a safety hazard and should be fixed by the manufacturer. Thank you.

I was driving the vehicle at normal speeds and I have had this vehicle for about 6 months and never have had a problem with it. All the sudden I get a message that says "service air bag". I took the truck to the dealer and they diagnosed it and they said that the truck needs a new front drivers side impact sensor that went bad. This truck has never been in an accident and the airbags have never been deployed. They told me that if this repair does not get done, if I have an accident the airbags wouldn't deploy.

This truck has experienced two fuse block failures since new. The symptom, in both cases, was the truck would not start. Both repairs were accomplished at brown and brown Chevrolet in mesa Arizona. The first repair occurred in 2008 and the second repair occurred in 2012. When reimbursement was requested for the second failure, the brown and brown service person and the GM customer care person both denied warranty coverage because there are third-party devices installed in the vehicle. There is an alarm system and a kenwood stereo, with a GM module, installed that were deemed third-party. There is also a cb radio but it was not cited. All vehicle equipment is powered through fuses on the fuse block. None of the fuses were found to be blown by brown and brown, including the ones powering the third-party equipment. The fuse block"S intent is to distribute power to such devices and protect the wiring with its installed fuses. Properly connected equipment may blow a fuse but cannot stress the fuse block to failure. I requested the ?bad" fuse block in both cases and have disassembled the second one. I found loose power pins and no evidence of burning or arcing. The design permits the power pins to loosen over time, causing intermittent connections. This intermittent connection was verified by brown and brown; they said that simply leaning on the fuse block would cause the engine to stop. This is not an effect of third party equipment but is a design defect of the fuse block.

Speedometer failure and RPM indicator failure on cluster panel. Cause X25.168 stepper motors are failing. For 2005 model year the recall only covered vehicles manufactured in 2004 up to Jan 2005. My vehicle was manufactured in March 2005. Clearly the same defective cluster assembly was still being used in the manufacturing process. Vehicle was purchased new in July 2005. GM recall needs to be expanded as there are numerous complaints for this same issue beyond the current recall parameters.

Speedometer stopped functioning. It displays I'm driving @ 120 mph and gets stuck there, when I'm only going approximately 30-40 mph. This is ridiculous that there is no recall on this malfunction as I see there are plenty of compliants with same issue. How can I drive safely without knowing the speed limit I'm going.

A private mechanic repaired the resistor in October 2008; however, the failure occurred again.

I was driving along when the cab filled with smoke and a burning plastic smell. I saw smoke come from under the passenger side dashboard. The blower motor resistor harness had caught fire. I was able to put it out with damage to only the harness and resistor. It was replaced under the extended warranty I had purchased from GM. Fast forward to May 9, 2010 and 50,000 miles later, the same thing happened and GM corporate told me there was nothing they could do even though this same model vehicle has been recalled in Canada for the same problem. I was quoted $300 for the repair. On May 10.2010, my dealer called and said he received an E-mail from GM stating that GM was in the process of offering a 10 year 150,000 mile warranty on the blower motor and harness repair. Have not received any notice from GM yet but dealer said they would fix it no charge.

The problem is the fan on GM trucks burns out. We were told by the service dept that the wires were burned up and that this required more parts and service. Needed resistor, connector and blower to repair. This is a potential fire hazard which is not being addressed by GM. Apparently this is an issue that many vehicle owners have experienced but since no one has been killed I guess there is not reason to mandate a recall. We were told by the service dept. That many vehicles are being brought in for service because of this problem. This should be looked into. Our vehicle has 38,000 miles. We have a friend who lives in NJ that had the same problem within a year of purchasing his new truck.

I also have a 2005 Silverado an the speedometer is stuck at 120 it has gone down as far as 60 but when you drive it pegs out and remains there. There were no warnings just happened around 82,000 now at 86,000 and 6,000 miles out of warranty. I feel that this is a safety hazard because I don't know my speed but I am lucky enough to have been given a gps to do that. I looked at GM website but they say I am over mileage for repair and I don't have the money for the repairs myself an feel this should be remedied by the manufacturer since it is a well know problem of theirs and this defective equipment.
