I bought the 2002 trailblazer on february 2008 drove it for about a month and a half total the rest of the time it has been back to the dealership for repairs. Everything including the motor needed to be replaced, the transmission needs to be replaced just accelerated onto the gas heard a loud crack and the truck shook like an earthquake had hit, lost acceleration would not go any faster than 30-35 miles an hour and car would not disengage from neutral at first and the would not go into reverse., brakes have made a pulsation feeling and they were done days before I bought the vehicle and replaced again including rotors a month after I bought the vehicle, there have been too many crackling and metallic tinging noises that don't go away, the 4 wheel drive engages and disengages on it's own when driving 65-70 miles an hour. The steering wheel had a constant rubbing noise and dealer told me all of my complaints were nothing detrimental and basically blew me off. The truck jerks alot on it's own doesn't matter if I am in motion or if I put it into gear or park it jerks. I don't feel safe in this vehicle, it seems to be possessed. I am scared to death to drive it, so I have stopped driving it. I don't know what to do. My first car was a chevy and now this one, I will never own another chevy product. I don't know what to do, I don't want this. I fear my own and everyone else's life!!
2002 Chevrolet Trailblazer transmission complaints
Page 5 of 11: complaints 101 to 130 of 310, newest first, as owners wrote them.
I bought a new 2002 chevrolet trailblazer in january 2002. When I reached 50,000 miles in 2004, reverse and 4th gear suddenly stopped working. I had the transmission rebuilt and sun gear replaced at aamco of charlottesville. Now I took, at 99,000 miles, it in for a fluid change and was told the fluid looked bad and they were concerned I might have more transmission problems. Transmission rebuilt should not be needed every 50,000miles. I do mostly highway miles, and very rarely tow anything.
I purchased a 2002 chevrolet trailblazer from younger toyota in hagerstown, md on may 12, 2007. Approximately a week and a half afterwards, I contacted the salesman that sold us the vehicle, phil young, complaining that the transmission was making a noise and the vehicle wasn't shifting correctly. He told me to bring it in to the service department. My husband (not car savvy) said that the noise was coming from the underside of the trailblazer and felt it might be the brakes causing the noise and jerking. I stuck to my guns that it was the transmission and wanted it repaired while it still had the 30 day warranty. Younger denied it was the transmission and noted my husband's theory of the brakes, but nothing about my complaint concerning the transmission. The trailblazer was taken back 2 or 3 more times to the service department, we demanded they fix it. The trailblazer sat in their lot for three weeks because we would test drive it and bring it right back stating that the problem was still there. On or around january 14, 2008 the trailblazer broke down in charlestown, wv. We took it by creamers automotive, they asked what the symptoms were and the mechanic drove around the block with me, instantly stated that it was the sunshell in the transmission and that they had someone in earlier that week with the same problem. They had purchased their vehicle at younger automotive as well and they denied the transmission problems and wouldn't note it on their paperwork as well. In my research of this problem, I found it to be very widespread, there are hundreds of complaints on one website alone. The sunshell is a faulty part that should be recalled by gm. Someone is going to be hurt or even killed if this isn't taken care of immediately. Gm is fully aware of this problem, there have been hundreds, maybe even thousands of complaints on this particular vehicle and should take ownership of a product they produce and sell.
This vehicle would go out of gear without warning because of a faulty 4 wheel drive switching system. This occurred in traffic, and an unoccupied park situation. The vehicle went out of park and rolled into a door while in the garage. The vehicle also went out of gear in traffic situations causing the driver to find the road shoulder. If the driver manipulated the switch it would sometimes re-engage the transmission. An encoder motor sensor was replaced, then failed in two weeks. It was then diagnosed that the encoder motor was faulty and causing the encoder sensor to fail. Replaced motor and sensor again. This is a defect that should be part of the existing recall for all 2002 chevrolet trailblazers, not just the select few as prescribed today.
When switching from 4 wheel to 2 wheel drive the transmission would occasionally disengage causing the vehicle to roll when parked, or disengage while driving.
Have a 2002 chevy trailblazer- son was driving vehicle in wyoming 20 below zero loud clunk and then grinding noise and he stopped there was no 2nd or 4th gears and no reverse. Luckily someone stopped to help him and he was ok. My car only had 51,000 miles on it. I called dealership they took it in warranty was gone repairs cost 3,420.00. I started researching complaints about the transmissions and realized there are over 82 complaints and that gm has known about this faulty part called a sunshell that's weak metal and the tork in the engine of the v6 cant handle the pressure so it eventually cracks and breaks then you dead in the water. This could have been a real safety hazard and for many I have read about their problems with children in the car its amazing no one have been killed yet. Gm refused to have a recall on this problem due to the expense and is passing this down to its consumers to bear the burden. Will I purchase another gm car? Not on your life! To anyone who has this vehicle check out the transmission problems on line and contact gm if yours goes out maybe they will step to the plate and help people who paid 32,000 for one of their vehicles!
Transmission problems. Locked two back wheels for seconds and back to normal. Big scare on the road. After that no reverse was possible. Ended up in shop. Closed to 2500.00 in repairs.
The 4 wheel drive randomly engaged and the selector lights would switch between awd, 4hi, & 4lo. This occurred on three separate occasions. The 4 selector switch now has gone out completely.
I own a 2002 chevy trailblazer lt. At 56,000 miles I had to have the transmission rebuilt. Then on march 12 2007 I took my car into the dealership to get the four wheel drive switch fixed because it was stuck in auto 4x4 after spending very close to a $1,000. We are now having the same problem again. Front wheels stuck in awd while the rear wheels are stuck in 2wd.
Tl*the contact owns a 2002 chevrolet trailblazer. While driving approximately 50 MPH, the contact heard a loud screeching noise underneath the vehicle. The check engine light illuminated on the instrument panel. The dealer rebuilt the transmission and the sun shield. One year later, the failure recurred and the dealer made the same repair. The failure recurred for the third time a year later and the dealer stated that it was an internal transmission failure. The contact filed a formal complaint with the manufacturer. The failure mileage was 45,000 updated 3/5/08 *cn the consumer stated second failure mileage was 77,000 and the third was 167,000 miles. The consumer further stated the dealer rebuilt the transmission and sunshield 1st and 2nd time but refused the third time. The consumer stated the dealer replaced the 4 wheel drive switch because it kept blinking. Updated 03/05/08
My 2002 chevy trailblazer is having problems with the 4 wheel drive system. About a year ago when my vehicle was still under warranty I had a problem with my 4-wd system, the dash said service 4 wheel drive. I took it to the dealership and they plug it in to the computer and said they recalibrated the system because it was a computer error not equipment failure. On dec 5 of 07 the roads were snowy so I put my vehicle into 4 wd, but the 4 wd did not engage and I slid off the road and almost ended up in a ditch. After that incident the service 4 wheel drive light came on again, on dec 6 of 07, I took my vehicle in for service, and now my vehicle is out of warranty, this time the dealership said my 4-wd actuator was shorted out, my bill came to $838.07. I contacted seven of my friends who have the same make and model, a couple with newer models, and they all except two of them, have had the same problem with the actuator shorting out. I then contacted gm corporate office on this matter and ask for assistance in paying for this repair due to faulty equipment and I said there is no reason for this part to go bad with 70,000 miles on a 2002 trailblazer, they told me that due to my year of vehicle and miles there was nothing they would do for me. I told them there are other cases in the area with this same problem and I asked them to investigate this because it needs to be a recall, or find out what the problem is and fix it before other newer models are sent out with the same problem, and somebody actually gets hurt because of equipment failure. Gm stated there is nothing they will do with this unless it turns out to be an actual recall. So here I am making a complaint and asking for help. This needs to be investigated and solved before somebody is seriously hurt due to gm equipment failure!!! Please help!!!!
My 2002 chevy trailblazer has had multiple drive train/transmission failures. It currently has 99000 miles on it and has been in for transmission complaints/work on 5 separate occasions. The last occasion being nov. 28, 2007 at which time the car would roll backward while in park. Upon removing the transmission pan metal shavings were found. Currently this vehicle is at the dealership awaiting service/ call back from general motors corporation customer care as to whether they will cover failure due to the warranty of 5 year was up 8/31/07, with some transmission parts warranted from repair at 90,000 miles. However, the chevy service garage cannot guarantee that it is the previously repaired parts failure, therefore cannot guarantee coverage under warranty. I have 2 small children that are with me daily in this vehicle, I have had to have it towed due to transmission failure twice and now the vehicle rolls out of park. These aforementioned facts make me fear for the safety of myself and my family in this vehicle.
2002 chevy trailblazer total transmission failure at 25,478 miles. Sun shell stripped in transmission causing near fatal accident in intersection in ft.myers,fl.causing loss of control of vehicle, 01/12/04. Need complete recall of this transmission. Sun shell defective not holding up stripping, metal to thin 1/16 and stripping out causing loss of control of vehicle and causing transmission to fail. Also clutch fan failure at same time, 01/12/04. Many reports of 2002 trailblazer transmission failure at many dealerships. Time for gm to take care of this issue before someone gets hurt or killed because of this well known problem gm has with their transmission failure due to a defective sun shell. Alfred j. Attard
Tl*the contact owns a 2002 chevrolet trailblazer. While driving approximately 45 MPH, the contact heard a loud noise underneath the vehicle. Upon arriving home, he discovered that he could not shift into reverse. Chevrolet has not been notified. The current and failure mileages were 53,673. Updated 12/12/07
Jan/feb 2007. Switched trailblazer into 4 wheel drive high for first time since purchase (april 2006), and would not transfer into 4 wheel drive. Took to local gm dealer, replaced control module, cost around $700. October 24, 2007 while trailblazer was in park and running the vehicle changed from 2 wheel drive to 4 wheel drive low. The switch was still in the 2 wheel drive position. The vehicle would not change back into 2 wheel drive at all. I took the vehicle to the gm dealer and they replaced the encoder motor. November 20, 2007. Left vehical running while in park. Went into a family members house,then returned to vehicle and began to back out of driveway. As I was backing up, the vehicle stopped, as if I had backed into an object (ie, another car), I pulled forward back into the driveway, and looked around, saw nothing, and was going into the house to get a flashlight when they noticed that yet again, the trailblazer had changed into 4 wheel drive again. This time I was able to get the vehicle back into 2 wheel drive, and drive the vehicle home. I have made an appointment to have the 4 wheel drive system checked again. Total cost for repairs to 4 wheel drive system january to date is more than $1200.
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.
I purchased a 2002 chevy trailblazer the transmission went out at 15053 miles with previous owner 2-3 shift solenoid in transmission replaced. The transmission went out with me at 33431 miles, still under factory warranty. Dealership found shell stripped out reaction carrier teeth broke replaced all clutches replaced 2/4 band. At 83029 miles transmission went out with me again. Vehicle is now out of warranty. Dealership found reaction sun gear stripped inside reaction sun shell. Replaced sun gear and shell & o/h transmission. I called gm customer service and asked them to replace the entire transmission because I felt something was causing these parts to keep going bad and this is the 3rd time. I felt there could be one part that came from the factory in this transmission as a defect. Gm agreed to pay parts if I paid labor to replace parts not replace complete transmission. This cost me $840.00. Now it is 119000 miles and transmission gone again. I called gm to explain to them that this is the 4th time and I requested a new transmission and a refund of my $840.00 from last time because for some reason this transmission has a pattern of going out at approximately every 30 to 40000 miles. Gm would not assist me with any assistance. The diagnostic this time shows would not shift out of 1st but to determine what parts were bad it would have to be broken down. I was hoping gm would assist me in this matter but I seem to get no where. I hope you can help!
My wife heard a clunk when driving. She asked me to drive the vehicle the next day and the transmission failed.
Fan clutch in 2002 chevy trailblazer went bad.
Transmission has failed at 55,000 miles, not driving car but was about to run errands. Have had to replace power steering block, alternator, starter, tail lights, instrument panel, radio and electric on a car that is just over 5 years old. The instrument panel, power steering block and transmission are all not under warranty.
Tl*the contact owns a 2002 chevrolet trailblazer. While driving 45 MPH, the contact heard a loud pop coming from the engine compartment. He stopped and turned off the vehicle. The vehicle was unable to be restarted. There were no warning indicator lights present. The vehicle was towed to the dealer and they stated that a new transmission was needed. The current and failure mileages were 53,600.
Needed new transmission for 2002 chevy trail blazer. Only had 61,000 miles. Cost $2,650.
Loud noise in transmission this after 30,000 miles on a totally rebuilt transmission of my 2002 chevy trailblazer.
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.
I have a chevy trailblazer ltz 2002,"bought it brand new" excellent condition 75,000. I had a transmission flush done at 50,000 miles as requested. I get oil changes done every 3,000 miles. On august 5th 2007 I noticed transmission fluid splattered all over the under carriage of my vehicle and the back window. Took the car to a my mechanic who recommended I take the car to transmission specialist "amoco"so I did. Need my transmission rebuilt, fluid leaking out of air port in transmission, the drums defective.
Went to get gas for my 2002 chevy trailblazer and we I finished and I started my car I put it in reverse and heard a loud clunk noise and then the truck would not go into reverse. Then I put it in drive and heard a lot of grinding. I called gmc and they know the trailblazer has a defective transmission and now that I call them with my problem they tell me that I just need to get a gm diagnostics test. Done and it just another way for them to get money out of people.
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.
I have a 2002 trailblazer. The transmission has failed twice since I bought it. The first time it was at 26,990 miles and the second time it was at 61,062 miles. Both times the transmission failed it was without any warning while I was driving it. The transmission would not move from 1st to 2nd or 2nd to 3rd unless I took my foot off of the gas. In both instances I also lost reverse. The first time it happened I was lucky because it was under warranty. The second time it happened it was 2 months and 1,000 miles after my extended warranty expired. The dealership quoted $2,038 to fix it (not replace it) but offered me a 10% discount. I didn't have a choice because I needed my vehicle. Since then I have found that this is a frequent problem that gm is aware of however they will not make a recall. What are my options? This is definitely a safety concern as there is no warning when the transmission fails.
I recently purchased a 2002 chevy trailblazer, and it's about 86,000 miles on it. At about 100,000 my transmission went. I did some research, and found out that there were many people who owned this same vehicle who had the same exact problem. I also learned that this piece that is used in the transmission called the sun shield has been the problem for a lot of people. The transmission specialist that fixed my vehicle told me that this sun shield is a faulty, and a lot of gm, and chevy owners have problems with it. There is a huge amount of people out there that are having this same problem with the same 2002 chevy trailblazer. I was driving on the highway, and suddenly felt that something was wrong. I am just happy that I pulled over when I did, because there was a lot of traffic that day. I was very scared, because I was alone in this car, and also I did not want to be hit from behind when I was pulling over to the shoulder of the highway. I called the gm dealer, and they said that they could do nothing for me. Even when I explained to them what had happended, and that this had happened to a lot of other people. I was told that my car was not under warranty, and this was not one of the many recalls that this truck has. I then had to fix this truck myself, and it cost me 2,300. The sun shield was replaced by something called the beast which I was told would be very very durable unlike the gm sun shield part.
