While highway driving with cruise control engaged I heard a loud whining sound and experienced a sudden loss of power. I was almost hit from behind several times before I could get the vehicle over into the right lane. When I took the vehicle to my mechanic I was told the cooling fan clutch assemble had failed. I have had this fan replaced three times now and am not at all pleased that this vehicle has not been recalled for this problem. I have read that this is a "common" problem on this vehicle that can cause a severe accident. I have receipts for the repairs but have no way to upload them.

What owners say
We just left the house to take the kids to get so food and we made it like fifty yards from the house and the tranny made a popping sound and so we stopped and tried to go and it wont move either way so I pull it back to the house and I start it up and the tranny is whining and I put it in reverse nothing happens so I put it in drive and it goes forward but wont shift.
I'm driving down the road with traffic behind me. Suddenly my RPM jolt up to five a horrible noise comes from engine and I loose all power. If I even touch gas a little RPM jump to five and transmission whines very loud. Car behind me slams on brakes to avoid hitting me. I throw on cautions and have to push my car off road while cars are trying to ger around me at ten at night on my way home from work. I have to have my husband load our three kids in his tiny eclipse well after bedtime to drive the 40 minutes to come get me and pay 150 dollars to have car towed off side of road back to my house. Where it now sitting with blown transmission and broken transmission lines.
Tl*the contact owns a 2002 chevrolet trailblazer. While attempting to place the vehicle into reverse, it failed to move and a whining noise was coming from the engine. Through online research, the contact found the federal safety agency campaign id number 01v283000 regarding the transfer case, but the VIN was not included in the recall. The contact feels that this is a safety issue because the vehicle cannot operate in reverse. The current and failure mileages were 142,002.
Transmission all of a sudden starting not going into gear and there was a whining sound. The reverse went out and it skips from 1st gear to 3rd. It will cost about 1300 to repair but I have not done it yet, as I cannot afford it. This seems to be a major issue for many trailblazers due to a defective sun shell part and really should be recalled.
Tl*the contact owns a 2002 chevrolet trailblazer. The contact stated that her engine has been ticking and making whining noises during acceleration, and performing very poorly. The service engine soon light illuminated intermittently. The contact took her vehicle to her local mechanic and they stated that the engine needed to be repaired. She was able to locate a dealer's special policy related to service bulletin number 060603. The dealer and the manufacturer informed her that a diagnostic would be needed to determine the cause of the failure, which would cost approximately $2,800. The contact stated that she takes her vehicle to the dealer for routine maintenance as specified by the manufacturer. The vehicle has not been repaired. The failure mileage was 72,000 and current mileage was 75,000.
I was driving down the road (fortunately in a 25 MPH zone) when the transmission made a loud clunk then whine, after which the engine revved and I lost any ability to change gears. After stopping the car, I found only the reverse was not working - the other gears will shift over 3000 RPM. I have been told it is a faulty sunshell gear in the transmission.
I had several instances of the engine revving up before the vehicle would shift. These were usually when the engine was cold so I assumed that was the problem. However 5 days ago the transmission went out. The engine revved really loud, the tach number went way up, suddenly the vehicle clunked & jerked into gear it then made a whining noise & when I got home (drove it real slow & not far from home) there was no reverse. Chevrolet says there is not a problem with these transmissions & they have not received very many complaints on this problem. My transmission repair shop told me this is the third one in 3 weeks with the exact same problem. Chevrolet is refusing to do anything about this. There are numerous web sites full of postings of people with the same problem.
Pulling onto the highway, when transmission popped and began to whine. Reverse gear lost and stuck in 1st gear. Took to dealer where diagnosis was failed (stripped) reaction sun shell. Fortunately vehicle was traveling at low speed. Concerned that failure could have occurred on the highway at greater speed. This vehicle was never used for towing or subjected to any abuse whatsoever. This is a common failure in the 2002 models built during a certain time period. Dealer gave some cost concession on transmission replacement, but unwilling to admit component weakness. Called gm customer assistance line with no additional support.
As my wife was pulling out of an intersection the trailblazer may a loud sound and then started making a loud whining sound that got louder as she drove and had no power and would not shift and then lost reverse. I contacted gm after I found that several people have had the same problem they told me to take it to a gm garage and have it diagnosed and they would be in contact with me they finally told me that they could not help me because 1st I did not buy from a gm dealership, 2 I did not have my service and maintanance done by a gm garage and 3 because I was a second owner of the trailblazer. So intern I had to pay $2730.27 to get the transmission replaced.
While driving my 2002 chevy trailblazer, I heard a loud chunk in the transmission and then a whining noise and loss of power. There is no reverse and the transmission slips when going through the gears, it finally engages but takes some foot work.
I was driving my car home when the car would no longer accelerate. All it would do is make a loud whining noise when the gas pedal was pushed. With less than 70,000 miles on the car and regular maintenance, there should not be an issue with the transmission. I nearly had a wreck just trying to get off the exit ramp and to the nearest auto shop.
