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 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.
Passenger side upper ball joint came out causing the lower ball joint to also come out resulting in a cut abs sensor wire and a bent strut and finally a axle that ripped out of the transfer case which destroyed the case cover.
Vehicle was bought brand new from gm dealer on oct 31, 2002. Vehicle has 71,770 miles on it. Was driving less than 6 miles to work in the morning and gave it gas and felt something break. Forward gears had little power and had a high wining sound to them. Had no reverse gear. Had to have vehicle towed. Dealer diagnosed it over the phone. Dealer opened the transmission and found the reaction sun shell in the transmission stripped. Dealer stated they have repaired these before, it was common occurrence in gm vehicles due to poor quality of metal used in transmission. Dealer had to tear apart transmission, remove drive shafts, transfer case, install new sun shell, related seals, and bearings. Gm refuses to acknowledge any problems and refuses to reimburse cost of repairs. Total cost of repairs was $1079. 45. Not known if old parts are available.
Purchased 2003 Trailblazer in October 2003. Had problems shifting into 4wd in winter 2003-04. When switching into and 4-wd, lights would flash and it would remain in 2-wd. Service 4wd light came on soon after. Brought it to the dealer who could not replicate problem. This happened later the same year and also the following year, each time the dealer could not find a problem. This past weekend while on vacation, a parking valet for some odd reason, switched the car into 4-wd low. Car will not come out of 4-wd low. Had to leave at dealer 150 miles from home and rent a car to get home. I am waiting until after the 4th of July holiday for them to look at car and figure out problem.
Drove car to a friends. Had to park in the mud. Came out later to find that the 4wd was not functioning at all. No lights no attempt to switch into awd, 4 hi, or 4 lo. Would not like to be out in snow and find out that 4wd does not work on a rear-wheel drive car. Could cause an accident.
While putting the vehicle in 4-wheel drive it began to accelerate. Vehicle ran into a guard rail and rolled down into a ditch. Owner contacted the dealer, who said it was the fault of the driver. Later, dealer contacted the owner, and informed him that the 4-wheel drive key was broken.
Gm t-body 4 wheel drive vehicles 2002 > loss of control during 4-wheel drive conditions. Transfer case shifting in and out with out warning, causing a slide and spin out condition. Have been in touch with gm and was tolds condition is normal. They blame the driver is driving too fast for conditions. Other vehicles have not lost control under the same conditions and speed.
While driving, the consumer noticed that the four wheel drive indicator light flashed intermittently. The dealership serviced the vehicle, upgraded the computer system and replaced the transfer case.
While driving consumer noticed that 4-wheel drive indicator light flashed intermittently. Dealership serviced vehicle, but could not duplicate the problem.
When disengaging the 4-wheel drive vehicle jumped forward hitting a parked vehicle.
'03 Trailblazer has been back to the dealership 7 times for the same problem, the 4 wheel drive engages by itself at 55 to 60mph, the truck jerks and it flashes from 4 wheel to 2 wheel drive, they have reset codes, changed switches and it still is doing the same thing. It has this problem at all speeds, it just is very noticable at higher speeds, the way the truck jerks. . I have filed with the bbb.
Upon cranking the vehicle the service 4wd indicator light in the gauge console area lights up, while at the same time the selector light for which setting the transfer case is in goes out. The selector switch is in the 2wd setting and there will be no amber light indicating it. You can switch the selector to awd or 4wd or back to 2wd and no indicator light. Sometimes it can me "fixed" by turning the vehicle off and restarting the engine.
Problem with 4x4 shift indicator not registering transfer case position.
Transmission locks up, 4 wd lights move on its own, this has happened 4 times since I have owned this car, I requested that I do not want this car back, but they insist they fixed the problem, now with my children 2 and 16 years in the car the 4wd light was malfunctioning and the car locked up and we skid down the street. I donot want this car back, I feel it will kill one or all of us with this lock up of transmission and the car won't move thank god it has not happened on the freway I feel we would be dead. The cars a lemo0n and I am not waiting for it to harm my familly.
Cosumer states the vehicle four wheel drive would not engage while driving. Vehicle taken to the dealer for repirs and the problem would reoccur. Feel free to provide any further information.
