A couple of months ago I took my vehicle in for several complaints and a repair under warranty. I explained to the dealer the loud fan noise, loss of power during this noise, which happened occasionally upon start up and disappeared after a mile or two of travel. At this time I was told they could not locate the problem. Now the noise is constant. I had a mechanic drive it during this noise and he indicated it was a failed clutch fan. In my research to find a tsb (aka technical service bulletin) related to my issue, I was able to find such a bulletin, amongst many customer complaints with the same issue.

Air conditioner cooling becomes intermittent. GM dealer commented that they have been having a number customer complaints about this issue and have been having of " a lot" of problems with the fan relay sensor and the cooling fan clutch. Repair calls for replacement of entire fan assembly and sensor/switch. Cost of repair approx $1,000.

Already replaced the fan clutch at 39000 miles. It cost me close to $800, $300+ for the new fan, and $400+ for labor. The dealer installed the new computer software. Now at 42700 miles the fan clutch, the thermostat broken. The bad news, I shipped this Envoy to the dominican republic, already talking to the local dealer. My question to all was, in observation of all the fan clutch problems, did this require a recall. Now, that I knew about so many people having this problem, either the dealer and GMC refund me for the first fan clutch and repair or replace with current one, or I will definitely sue them. Has anyone taken this action?

Engine tended to rev at a high level until warmed up. Finally would not come down to a normal level due to a failed fan clutch. Vehicle was out of warranty, and dealer quoted $800 for repairs. Had the fan clutch replaced independently, which now has us back to the original high level of revving for several minutes before running normal. Disappointed to see the number of similar failures, and yet the dealer acts like this is an unheard of event.

I drive a 2002 GMC Envoy and for the last 2&1/2 years during the summer, I usually notice that the fan seems to run very frequently. After a few minutes it usually stops and I don't think about it again until we restart it. We've taken it to two different dealerships including the one we purchased it from and they tell us there is nothing wrong with the car-it's just hot outside and the engine needs to be cooled by the fan so it runs longer and louder. Today, I took it in because it would not quit running and my check engine light came on. They want $700 to fix the fan clutch which we've been trying to tell them wasn't operating correctly this whole time.

Last year (2005) the clutch fan locked up and stayed locked up until we took it to a GM dealer. They said there was a bulletin on this and the PCM needed to be re-programmed. That solved the problem. The vehicle looses power, won, T shift properly and this happens without notice. One minute it's fine and then it's not. Now one year later the same problem has occurred. This is ridiculous!! I now have to take it to a dealer and pay to have it re-programmed. If this is a continuing problem, I don't understand why GM can't just replace the chip that holds the code, and be done with it.

I am writing to file a complaint regarding my 2002 GMC Envoy. It has 46550 miles on it and the fan clutch has failed on it. After searching online I noticed that this seems to be a very common problem with these vehicles I.e. GMC Envoy/Chevy trailblazer. The dealership is offering to fix it for $900. I will have it fixed, I don't have a choice, but I will keep the old part just in case anyone ever needs to see it. I'm hoping that one day your Agency will SE that this is a real problem with these vehicles and recall them. Thank you.

This is my second letter to your company GMC. Plain and simple all I am looking for is the value of my investment. I have no desire to get anything free nor am I just trying to get a new vehicle. The 2002 Envoy I purchased from you a year and a half ago would be fine if I did not have so many problems with it. About a month ago it had to have a new motor and this past week it had to go back to the shop to have a fan replaced at a cost of $800. I expect that next month I will be paying $500 plus dollars for some other repair. I knew that once this repair was done to the most important system of the vehicle I would have major problems for as long as I have this Envoy. I am not going to allow this company to keep me in this situation. This is my final attempt to reason with GMC to work out some way for me to get a dependable vehicle that affords me the years of service any reasonable person would expect for a 30K investment. My GMC sr # is 1-5521-9927. I am quite aware of your assertion that you replaced the engine out of warranty free of charge. I would counter that claim by saying that the problems with the engine started long before the warranty expired. I have the service contract to show this. My point is I am still stuck with a 2002 GMC truck that has suffered a major engine failure and all the problems that come with that failure and this is just 2003. I would also say that the very fact that the engine failed so soon does not speak well of this vehicle or your company. I hope this is not the standard you have established for your vehicle. Now only a few weeks after the engine is replaced I am faced with the truck going back to the shop for a major repair. I still have not mentioned the other problems I have had with the Envoy. Letters to the better business bureau, and consumer protection Agency will also be written. Please send me a written response to this letter. Kelvin oneal buck, customer

Transmission does not seem to downshift; loud fan noise with loss of power; hard shift into gear from start; missing rear seat latch to hold down seat and easily wobbles when shaken; hook for latch is present but no latch present seems to be design flaw.

Service engine light illuminates, engine cooling fan engages, engine power greatly reduces and transmission shifts improperly. Loud noise from computer controlled engine cooling fan. Vehicle will not accelerate or shift properly when driving with fault. Fan clutch replaced, computer programming changed with no success of fixing problem. GMC refuses to buy back vehicle. Dealership indicates this problem is occurring on all 2002 GMC Envoy's at varying levels mine being worse case. Vehicle is unsafe for use in any traffic situation as the problem manifest itself rapidly with severe loss of engine power, loud noises from engine and poor shifting and acceleration.
