Chevrolet Trailblazer owners have reported 87 problems related to transfer case (under the power train category). The most recently reported issues are listed below.
Certain sport utility vehicles equipped with 4 -wheel drive fail to comply with the requirements of federal motor vehicle safety standard no. 101, no. 110, no. 114, no. 225, no. 209, & no. 208. Vechicles were built with a left -front brake pipe with a circumferential score at a random location along the lenght of the pipe as the result of the manufacturing process. If the brake pipe partially or fully fractured,brake pedal travel would immediately increase and front brake performance would be reduced under certain circumstances the front lower control arm brackets may fracture. Missing welds on the rear flow plan the calibration of the transfer case control module could cause insufficient high speed gear engagement. This fracture could result in separation of the front lower control arm from the frame some of these vehicles were built with a range shift collar in the transmission transfer case that contains cracks.

While putting the truck into 4x4 hi, lo, or all wheel drive, the transfer case never does fully put it into 4x4. While driving, the dim lights turn completely off. The brights work, but the dims do not. These will not turn back on until the truck is shut off or a proper bump is hit. The heater blower in the front sometimes will nit come on. The back will be blowing, not the front. Also if a bump is hit improperly, the back speakers will start buzzing.

The 2006 Trailblazer had issues with the 2-wheel drive/4-wheel drive actuator and sensor. I had the sensor replace under warrenty because the indicator light on the actuator handle was in a different range than what the knob indicated. After replacement, the truck indicator light would occasionally change while driving. There were no warning lights lights indcating that there was an issue with the power train system. The transfer case eventually burned up due to continuous swithing between high and low hears while driving. The truck lost power while driving at 65 miles an hour in mountainous and snowy conditions. The tansfer case, and sensor and actuator were all paid my the car owner.

My complaint is about my 2002 chevy Trailblazer. On the front right (passenger side) of the vehicle. Whenever I hit a bump there is an almost uncontrollable vibration. I have to bring the vehicle to a complete stop to make it stop. This started about two months ago and is gradually getting worse. I took it to a number of shops and they're all telling me the same thing. Transfer case. The cheapest estimate is about $1300 , and that is for a used transfer case. I love this truck and I really have not had any problems until recently. Then I started to read reviews and realized that I'm not the only one having this problem. I take very good care of my vehicles because I can't afford to keep buying new vehicles all the time,or very costly repairs. Just about every vehicle that I've owned has been 4 wheel drive and I've never had this problem before ,even on trucks with twice as many miles. I am hoping that there is something that can be done that may help me with this problem . I really can't afford a new truck and I don't want to repair it with used parts . By the way,the cost of repair with new parts is roughly around $2900 .
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 NHTSA 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.

I have 2002 chevy Trailblazer that transmission failed at 113,000 miles. Rebuilt at a cost of $2,000 by dealer. Also transfer case electronic modulator went out and replaced @ $800 by same dealer. Also replaced the fan clutch at same dealer for $800. Within 1 week I have spent $3,600. I have owned 6 new gm products and have never replaced this much expensive equipment. I know the transmission is a major issue and felt gm or the dealer should help on the repair. Dealer refused and would not request gm's help. The other items I am sure are related or replaced at a very high rate. Evidence of these repairs are all over the internet. My Trailblazer is driven by my wife to work and they are all road miles. I did not expect to pay for all costs but they could have worked with me. I paid $25,000 for this vehicle and expected a lot more. Gm does not deserve a bail out. They need a good ass kicking for the dumb asses that tried to support them all these years by buying their product. If there is help from all the bail out money they get include my $3,600. I would not expect a free repair but with the number of complaints there are they should be made to repair or reimburse on some kind of scale.
The contact owns a 2008 Chevrolet Trailblazer 4wd. While driving approximately 30 mph during inclement weather, the stabilitrak service light came on the dashboard. She stated that the stabilitrak does not work while driving over an ice patch. The vehicle was taken to the dealer for the failure who reset the light. The vehicle was taken to the dealer at least seven times for the failure; however, the failure continued to occur. The vehicle was not repaired for the failure. While driving 70 mph, the vehicle would shift from two wheel to four wheel drive low. The vehicle was taken to the dealer and they reset the light. Over a two year period, the vehicle was taken back and forth to the dealer and eventually the dealer replaced the transfer case. The vehicle was repaired. The approximate failure mileage was 15,000 and the current mileage was 70,000.

2003 chevy Trailblazer. Transfer case needed to be replaced in 2006, @ 32,000 miles under warranty. Transfer case needs to be replaced again 2009 @ 66,000 miles, warranty period over ,now its $2200. 00 out my pocket. After researching this is a well known problem with these transfer cases. The bearing installed can not handle it. Apparently gm has recently updated the bearing. Gm will not recall these transfer cases. Other gm vehicles have related issues with the transfer case.
The contact owns a 2002 Chevrolet Trailblazer. While attempting to shift the gear into reverse, the contact heard a loud noise. She continued to drive the vehicle and, once at her destination, unsuccessfully attempted to shift into reverse again. The following morning, she attempted to drive the vehicle again and it made very loud noises under the hood. In addition, the gear would still not shift into reverse. The contact discovered that she was experiencing the same failures mentioned in NHTSA campaign id number 01v334000 (power train:transfer case (4-wheel drive)). The manufacturer informed her that her VIN was not included in the recall; therefore, she would be responsible for the repair costs. The vehicle has not been repaired. The failure mileage was 141,660 and current mileage was 141,694.
The first major problem I had with this Trailblazer I was driving down the road at 65 mph when for some reason the 4wd decided to shift into 4 low on its own. Well, this ripped out the cv joint half shaft on one side, destroyed the transfer case internals and broke off the axle housing from the aluminum oil pan on the engine. Ok, I got that fixed, added a new selector switch, then a few thousand miles later the transmission goes out while I'm on the interstate. It was completely destroyed inside. The transmission shop had to find a new core because mine looked like a bomb had went off inside it. So , I'm thinking it could have been caused by the first problem, maybe a delayed reaction? ok, we get a rebuilt transmission in it and just out of warranty it goes out again. No towing mind you, just easy highway miles with a mind on trying to get the best fuel mileage possible by driving like there was an egg between my foot and the accelerator pedal. So, I go to another transmission shop this time. Maybe the first guy didn't do a good job I'm thinking. So the 2nd transmission guy tells me that's not uncommon for the 4l60e to go out like that, they're garbage. So he puts me in a new tranny. Well, sure enough 6 months later it lost 3rd and 4th gears. The local shop is not to blame, these transmissions are junk. Many have flaws in them and gm knows it. So what are they going to do? unless I receive a recall notice on the transmission, the Trailblazer will keep its place in the backyard. Until the junk man comes around.
The contact owns a 2005 Chevrolet Trailblazer. Two weeks after the vehicle was purchased, the 4-wheel drive failed. When turning left, right, and when driving in reverse, the wheels lock when the 4-wheel drive is activated. The failure also occurred once while in drive, but all the other failures occurred only in 4-wheel drive. The dealer stated that the 4-wheel drive was operating normally. The manufacturer sent a technician to his local dealer to attempt to remedy the failure, but was unable to assist. The technician stated that the failure was located in the 4-wheel drive transfer case. The failure mileage was 35,678 and current mileage was 36,210. Updated 04/22/08.
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.
The vehicle transfer case has failed twice. The first failure occurred at 33,377 miles. The dealer repaired the vehicle under the vehicle original warranty. The second failure occurred with 43,971 miles. (miles per each transfer case)the vehicle was idling rough and in 4wd. I selected the awd mode and the vehicle made a clunking sound but stopped idling rough. When I tried to put it back in 4wd it would not go into the 4wd mode. When I returned home I tried to put the vehicle in 4 low and it went into 4 low but would not come out of 4 low. The servicing dealer and gm claim the tc failure is because we live in a northern state and therefore use the awd and 4wd more than other regions. I spoke with another dealer and they claim gm is aware of this problem, but cannot fix it. The second dealer said they could repair the vehicle, but assured me that the tc would fail again. Both dealer said they see these Trailblazer tc failing all winter long. There were about 4 to 5 Trailblazers in the service dept (not including ours) with broken transfer cases.
While driving , the vehicle would shift from 2wheel drive down to 4 low, causing a very rapid decrease in speed and loss of control over vehicle, depending on driving speeds and rd conditions this could cause a very dangerous accident. I have had the vehicle into the dealer 4 times in the last month and they have replaced , 4wheel drive switch on dash, encoder motor on transfer case and reprogrammed stabiltrac, vehicle is still at dealer and trying to solve problem. Dealer has been very polite and understanding during this entire process.
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.
The failure involves the electro-mechanical device that shifts the car into four-wheel drive. The four-wheel is engaged by selecting 4wd with a dashboard selector switch. The switch will show a lighted indicator moving from 2wd to the 4wd. This indication is faulty. While driving towards a snow covered mountain road with several sharp turns going up the mountain the vehicles selector switch was moved to the 4wd position and the indicator light shown it was engage in the 4wd mode. However the indication was faulty and the vehicle was actually only in 2wd. The selector switch engages an actuator that causes a fork to move the gears in the front transfer case into or out of 4wd. The result of the false indication of the vehicle being in 4wd when it was actually in 2wd cause the rear of the vehicle to break traction and the entire vehicle to start into a spin which resulted in the vehicle leaving the road and damage to the front end of the vehicle. The main problem is that the vehicle gave a false indication of being in 4wd when it was actually in 2wd.
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!!!!.
