2002 chevrolet trailblazer -- while attempting to shift from 2hi to 4hi due to slippery road conditions the lights on the transfer case select switch flashed as usual. However, rather than remaining illuminated in 4hi, all the lights went out and the transfer to 4hi was not completed. The vehicle remained in 2hi. Turning off the vehicle and re-starting did not remedy the situation. On january 2, 2004 a chevrolet computer technican attached a computer under the dash, but could not get a reading. The technican opened the engine compartment fuse block and removed and checked the automatic shift lock control system fuse [mini fuse 25]. Whether he merely put it back or replaced it I do not know. However, after doing so, he worked some more on the computer and got the system re-set so it could be used. A subsequent check by my local dealer could not identify the source of the problem, but the did charge for re-programing the computer.
2002 Chevrolet Trailblazer transmission complaints
Page 10 of 11: complaints 251 to 280 of 310, newest first, as owners wrote them.
2wd 4wd selector switch changes position randomly. Caused a repair to front ring and pinion assembly in differential. Selector switch acted up at 50-70 MPH range. Cost of repair: $2000.00! Gm will not cover under any warranty. Based on other consumers complaints. I would think if gm was aware of this many complaints for the same thing, should there not be a recall! My father and father-in-law both worked for gm. I agree with another consumer that gm has no regard for the safety of their buyers. I'm considering going to ford!!! Unless gm will stand behind their "bread winner"??
Problems with vehicle's brake lights and alternator.*mr the car had problems since it left the dealership. The alternator had to be replaced, the 4-wheel drive switch was replaced, the car stalls, brake lights keep shorting out. It cost the consumer $263.49 to have the car fixed. The consumer was not satisfied with chevrolet or it's warranty. *cb
The vehicle failed to engage into 4-wheel drive. The consumer took the vehicle to the dealer. The mechanic will be doing a diagnostic test to determine the problem. Please provide further details.
The brake light went out multiple times without warning. The dealer was aware of the problem. There were no incidents to report at this time. *ak the consumer stated when the vehicle was warm, the was a noise in the front end, the dealer replaced the axle seal and bearing, the o2 oxygen sensor was replaced. The 4-wheel drive was inoperative. *jb
Had to replace the 2 wheel drive/4 wheel drive selector switch three times. Component fails without warning. The day this vehicle went into service the selector switch failed delaying delivery.
On a number of occasions, while driving in 4wd hi, vehicle automatically shifts into 2wd or attempts to shift into 4wd lo. On two occasions, while driving in 2wd it shifted into 4wd. Dealership could not duplicate problem, so they would not fix or replace any parts. Similar account to several other owners.
Electronic exterior rearview mirrors and power seat engage and operate by themselves. Dealership cannot fix the problem. *ak the memory for the mirrors and seat would not keep their position. When the consumer entered or exited the vehicle the systems would reset to a new position. Occasionally they moved while the vehicle was in motion. The dealer has replaced many components but the problem still exist. The check engine light illuminated. The dealer replaced the oxygen sensor. The A/C control mode button became stuck and was noisy. The dealer replaced the A/C module head. The left windshield wiper chattered and skipped. The dealer replaced the wiper insert. The 4wd switch fluctuated between 4wh and a4wh. The dealer inspected the vehicle and replaced the transfer case select switch. *ts
4-wheel drive failed causing vehicle to go from 4-wheel drive to 2-wheel drive without changing the selector. Dealership is unable to duplicate the problem, so they can't fix it.
While driving transmission fuse blew out which made it impossible to drive the vehicle.
Since I purchased the car there have been a number of safety issues. The first was the transmission. I brought the car into the dealership 3 times with complaints of the car having spells where it was difficult to drive and on two of those occasions it nearly caused an accident. The third time I had to stop the car on a busy highway and have the car towed in for repair. The have since repaired the transmission. The second issue was the car was stalling intermittentaly. The final time I had it towed in and there was some electrical issue they have resolved. I am currently trying to resolve the third issue with the car. The car engine is reving very loudly and if I accelerate beyond 40 miles/hour the car lunges forward. I have not heard back from the dealership yet but this is the second time it has been in on this issue. I would also like to note I bought the car from classic chevrolet and they lied about the safety features of the car. I was told that it had the latch system and when my son was born in may I found out that in fact it did not have the latch system. Gmc has stated that they have no way to repromand the dealership for lying about safety features on cars. I purchased this car because I wanted a new safe car to start a family and I ended up with a lemon of a car that is the most mechanically unstable that I have ever experienced. I ended up on the side of the road stranded when I was pregnant nearly an dozen times.
At medium to high speeds transfer case engages without warning.
On at least 6 occasions my trailblazer would not start, and on one occasion, while driving the transmission fluid spilled all over the road and the car would not move. I was stuck in the middle of the street for an hour and a half until the tow truck came. The dealership keeps telling me its the alarm system, but the alarm is not out of the car and it still doesn't start some time.
Ever since I bought my 2002 trailblazer I have had nothing but problems. I have a stack of paperwork of everytime I brought this into the dealership to fix and have had about 5 rental cars due to this. Now after searching this site I find there have been alot of recalls on these and I havent been informed about any of them besides the one for security. Please help me. Im a single mom with 2 children that ride in this truck. *ak windshield wiper module replaced under warranty at 48,594 miles.
Dont know where to start. Squeaking noise when going over bumps (sounds like it is coming from suspension). Metal grinding noise in brakes, ticking noise from engine, seat belt and airbag lights have come on for no reason, rear latch has come open while driving, tail lights and brake lights burning out freqently, transmission was slipping on take off, no cause found in the several times it has been taken in for this. Now my transmission is out. Just happened yesturday. Don't feel like I can blame the dealership after reading all the complaints. I think the fault lies on the shoulders of gm.
Transmission does not upshift. Engine at 3000 RPM will not go over 10 - 12 MPH. This will last from 1/4 to a mile. No power. Have taken to dealer, says that gm knows of problem. Regional represntative george bell does not return calls. No help from gm.
My service 4wd light has been a problem since january 2003. My 2002 trailblazer has been in the shop for almost all of july. Chevy has refused to repurchase my vehicle stating that they are going to "fix" it under the warranty. It goes without saying that I am fighting this. Additionally, upon my return from a three week vacation in march, I found my trailblazer completely dead. Chevy has not been able to to identify the problem.
Problems with 2002 chevrolet trailblazer. The headlamps went out while driving. The 4wd light appeared on the dash board, while driving, the gear switched to 4wd which caused the vehicle to jerk.*mr *ts. Also on 2 occasions the consumer was unable to shift the gear from park to drive.
When coming to a stop or accelerating from park vehicle automatically switches from 2 wheel drive to 4 wheel low setting without selecting that option. This has happened six times in the last year. The dealer could not determine the problem. The vehicle will be taken to the dealer again on 7/10/2003.
Problems with vehicle's transmission.*mr the transmission went into a mode which did not allow the vehicle to travel over to 15 MPH when the transmission was placed in the drive position. *ts
Service 4wd light comes on, vehicle will automatically go into four wheel drive without the switch being turned. This causes the vehicle to jerk and it is difficult to steer at times.
Problems with air bag dash light, fast engine idle, air conditioner, rear hatch inner strap broke, etc...*mr the airbag light was intermittent. The sir module was replaced, and there was poor terminal connection at the sir wiring harness, and was traced/repaired on the left side impact connector and the codes were cleared. The engine idled fast(especially at start up, and the fuel mileage was 13 mpg. The results of the evaluation and repairs were: passenger impact connector was loose(repositioned/connected), idle within specifics, the emblem had fallen off, the rear hatch inner strap had broken, the transmission seemed to take long to shift into gear(happened sometimes when cold), and the PCM needed to be reprogrammed(j6355 power train controller PCM). There was a thumping sound in the rear differential when shifted, the A/C would blow out cold air when the A/C indicator was off, hot air would come out of the defroster area on the dash when the indicator was set for heater on the floor, the engine made a tapping sound, the lift gate weather strip had come apart, and the battery kept losing charge(3 occurrences). *scc
While driving, the four wheel drive kicked in which caused the rear end of the vehicle to lock up.
Consumer was involved in a frontal and side collision while traveling approximately 60 MPH. Upon impact, the entire gear shaft came up out of the floorboard. *nlm
4 wheel drive failure light on dash board and "4 wheel drive full" and "4 wheel drive low" light keep flashing and when I placed truck in park and shut off truck, it lunged backward. Gas tank wouldn't take gas and the last time it spit gas out and out onto pavement. Brakes don't seem to stop very well and I now have a pulsating feeling under my foot when I brake.
Vehicle engaging into 4 hi, 4 low, and a 4 wheel drive spontaneously. While vehicle is in park and in 4 wheel drive, it has a whinning sound and will lunge when 4 wheel drive is turned off.
The 4 wheel drive did not perform as designed, which resulted in an accident.
While driving the vehicle at a speed of approximately 65-70 MPH, I felt a surge as if the transmission was shifting. As this was happening I noticed the light next to the four-wheel switch selector knob was blinking above the automatic 4hi position. This has happened on occasion quite frequently. My wife who normally drives this vehicle says it happens several times during a typical 60-mile trip. This same thing happened a week after we starting leasing this vehicle back in april of 2002. I told the dealership about it and they said they couldn't find anything wrong. They said it's hard to find something wrong with it when it's not actually happening in front of them. It always tends to happen in the speed range of 50-70 MPH. This issue has me concerned, especially while driving on snow, ice, or wet surfaces. I'm afraid it could jerk enough to throw us off the road. I've now realized, through the federal safety agency web site, that many trailblazer owners/operators have had similar problems and gm has done nothing to remedy the problem. I've always purchased gm since my father is a retired gm employee, but I'm now considering buying outside of the gm family. What good is the gm employee incentive/discount, when your life is at risk? Apparently to gm, the cost of life is nothing compared to the cost of a recall. I'm considering getting out of the lease, no matter the cost, due to the lemon of a vehicle we now have. How many people will be injured and or possibly killed before gm decides to bite the bullet and recall their bread-winning vehicle? Today (3-17-03) while in for normal service, I was told that the dealer reset the control module, which might fix the problem. I asked them about changing the switch and they said they have done this on some vehicles but prefer to start with resetting the module. Only time will tell. I hope the forecast is for dry weather!
On 11/02 I had my vehicle at the dealer for service & it was brought up that the 4wd was turning on & off randomly. The service person mentioned that they have seen a handful of these & the computer in the vehicle was "asleep" however, they advised they couldn't check the problem because it was in working order at the time I had it in. They could only check the problem if it wasn't working. The last week of 1/03, I was traveling at highway speeds in 2wd. The vehicle automatically shifted itself into 4wd high, made a very loud sound & the lights on the dash changed from 4wd high to awd, & 4wd low. When I arrived home, all the lights on the dash for 4wd were out & have not come back on. The vehicle was turned off. When the vehicle was turned back on the following day, it was in 2wd & would not engage into awd or 4wd high or low. I contacted my dealer who set up an appointment to bring the vehicle in on 2/5/03 to have the 4wd checked out. On 2/4/03 I hit a patch of snow & ice with my rear tires. I was traveling approximately 40 MPH on a 55 MPH road. Due to the vehicle only being in 2wd & the awd & 4wd not working, the front wheels of the vehicle had no power & the vehicle went out of control & ended up in a ditch on the side of the road causing over $4000 in damage. Minor bruising injury to myself when my knees slammed into the dash. Body damage has been repaired & the service dept has confirmed that the computer was not working at the time of the accident in order for the 4wd to turn on. The computer has since been "reset" & the vehicle returned to me on 2/27/03. Again on 3/1/03 & 3/3/03, the vehicle was in 2wd traveling at highway speeds & randomly turned from 2wd to awd & 4wd. On 3/10/03, I advised the dealer again of the problem & the manager is going to speak w/the service dept to find out if there have been any other complaints of this nature. Again, the dealer said they couldn't do anything now for me as the vehicle is working at this time.
Update of complaint 10003216. Grinding noise in transfer case recurred while driving on freeway at 65-70 MPH, with 4wd mode switch lights jumping back and forth between 2wd and 4wd. Stopped off freeway to call dealer, car would not move, towed to dealer. Told that the transfer case failed.
