The contact owns a 2003 Chevrolet Trailblazer. The contact stated that the fan clutch was failing and sounded like a plane taking off when pressure was applied to the accelerator pedal. She first noticed the failure in July of 2008. The vehicle was taken to a mechanic, who stated that this was a common complaint for this type of vehicle. The mechanic repaired the vehicle for $710. 68 at the contact's expense. The manufacturer stated that there were no recalls and could only make a note of the failures. The failure mileage was 78903 and current mileage is 94,000. Updated 09/18/09. The consumer stated even though the fan clutch was repaired, it continues to make sounds. Updated 09/21/09.

For approx. 2 years there had been a constant ticking when my 2003 Chevrolet Trailblazer was running. Questions about the noise was dismissed by the service technicians as normal. Finally on 3/22/08 my fan clutch failed causing an overheat problem and a constant loud noise, along with a service engine light. Upon investigating this issue I found literally thousands of complaints on the internet regarding the Chevrolet Trailblazer and its premature fan clutch failures. To correct the failure I had to incur the $724. 00 repair.

Bad clutch fan again!!!.

03 Trailblazer fan clutch failure at 48,000 miles. Lots of same issue complaints on several car sites. This should result in a gm recall.

My truck has been driving average, with prior issues of the truck sounding like it is struggling to accelerate. This weekend, it began sounding like it is struggling to accelerate. Because of this, I had to drive below the speed limit for over 50 miles for fear of my truck blowing up. After taking my truck to the dealership, the problem is the fan clutch. After going online, I observed that there are thousands of people who have had the same issue with Trailblazers from 2002-2007. But to no avail, I cannot find any recalls from Chevrolet about their many faulty parts. I am supposed to pay $900 to repair something that should be recalled from chevy? where is the justice? I am a family member of 3 generations of gm employees, and I am truly disappointed in Chevrolet.

I brought my 2003 Trailblazer in for service to my gm dealer while still under warranty for a ticking noise. The noise is intermittent and the periodic rate is constant regardless of engine speed rpm's. I now have 50k miles and the fan clutch motor failed and operated at 100%. Through research online, the ticking sound is directly related to the fan clutch failure many gm Trailblazer and envoy owners have experienced. The fan operates at 100% due to the fan clutch failing resulting in loss of power. I too have experienced what is described by many as the "lear jet" sound. The sudden loss of power at high speeds in my opinion is as safety concern and gm should recall this defective fan clutch motor. Customers with my 2002 and above have complained on several websites on this issue.

Ev cooling fan runs at a high rate of speed and does not disengage for serveral minutes while driving. The vehicle does not shift properly during this period of time. Since I am unable to get up to highway speeds, I feel I am a safety hazard to other drivers that must slow down until they can pass or I get up to proper highway speeds. I will be replacing this component at the dealer they gave me the following estimate: part cost $350 and labor cost $300. I will be asking for the old component. This problem began occuring without any warning. One morning it just began operating at a high rate when I started my vehicle and as stated, continued for serveral minutes.

2003 Chevrolet Trailblazer mechanical problems due to fan clutch defect. ***.

The engine fan clutch failed on my 2003 chevy Trailblazer the truck is only three years old with 65000 miles on it. I was told that gm has change this part several times to try to fix the problem I think there should be a recall on this part as the cost was about $630 dollars to have it repaired.

Fan clutch failed on vehicle that is only 3 years old. I have searched for info on this on the internet & have found page after page after page of other people having the exact same problem, all have had to pay $600-$1000 to fix the issue that seems to be very common on 2002-2004 Chevrolet Trailblazers. This needs to be a recall issue that Chevrolet fixes without charging its customers!!!.

Engine kept making this very load roaring noise. Had to get the clutch fan replaced like many other Trailblazer owners. Gm needs to recall this part!.

Fan clutch failure on my 2003 chevy Trailblazer car "roars" as the fan does not disengage and experience loss of acceleration.

Fan clutch failed in near full on mode causing excessive air flow when during winter season. After approximately 20 miles highway travel attempting to return from a vacation the "service engine soon" indicator illuminated. Readout of this error was p0495 fan speed high.

This vehicle was purchased new in Jun 2003. While still under warranty, various recalls were issued for steering, brake lights and rear hatch locking/handle assembly. Since then, the vehicle has been a lemon. Power steering pump replaced twice (first one I paid for, second independent and very reliable mechanic shop paid). Next the engine cooling fan bearing had to be replaced. Later, the transmission had to be rebuilt. I also had to get the computer checked and reset to avoid surging engine rpm and resultant speed deviations. Reaching a point of frustration as never before, I wrote gm asking for consideration repairing the transmission and received no response. I know they received the email since I had a "receipt requested" feature activated in my office computer. I sent a second email stating I was aware of the email receipt and that I expected a response. No such luck. All these problems manifested themselves well before the 100,000 miles were reached. Now at approximately 132,000 miles, I had to replace the exhaust manifold due to a crack, the vehicle has lost power on two occasions, the entire dashboard has gone to zero and back to normal several times and the latest is an engine noise that my very reliable, 6 year auto service provider has told be is related to the timing belt assembly/mount points and as it gets louder, the engine will be getting ready to fail. So, I read all these complaints today and felt like I could have summarized everyone's complaints and concerns. I am an accident investigator and have no doubt that this vehicle will go down in history as one of the most unreliable and dangerous cars ever built. Shame the feds have not taken the extra steps to remedy the issues after so many complaints yet, they went after top selling Toyota at a time when the american made cars were barely able to stay afloat. Wonder?.

Since I bought this vehicle August 30, 2002 I have had to bring it back to the dealership on numerous occasions for several different items. I have had both the left and right brake lights gone out, the driver side head lamp went out, the air conditioner has gone out twice(four months apart), the driver side passenger window is inoperable(we have tried to get it fixed for almost a month now with no success) and the engine cooling fan was warped and the fan clutch malfunctioned. At this point we don't understand why they haven't just recalled the whole vehicle. Luckily we have the 36,000 mile warranty still in affect but what's going to happen when it is up and the same problems keep recurring?.

Engine fan clutch is making a loud roaring noise (2003 GMC truck).
