| The problems that are happening to my 2004 chevy trailblazer : i am having a whining noise in the front end of the vehicle and when i try to engage into 4wd the sound worsens and there is a vibration in the front as well the whining almost resembles a low siren sound. i am also having a major malfunction with my speedometer since the weather has gotten colder??? i could only be moving 10mph and it will register to 120 or even surpass it and then get stuck, the only way to unstick it is to shut the car off and keep restarting it until it resets itself but now it is stuck and wont reset, i went online to see if there were any recalls and i all i found out was there were tons of people having the same issues with their trailblazers as i am having. these problems are occurring at all different times during the life of the car some people have them happen around 30,000 miles or some 50 thousand and myself the speedometer is happening around 72,000 miles. the speedometer seemed to start to act up once the weather was colder. its a shame they will fix the larger suv's due to a lawsuit but since this is a smaller suv it's not covered. we have tried to replace the wheel bearings in the truck for the front end noise to only find the noise did not disappear after reading many of other complaints from others it seems this could be the transfer case on the truck. i am not going to keep replacing part after part to only find out its the drive train and something should be done about this. *tr | |||

| Tl*the contact owns a 2004 chevrolet trailblazer. while driving 25 mph, the contact heard a rubbing noise coming from the front passenger side of the vehicle. she then noticed a burning odor coming from the engine. the vehicle was taken to a local repair shop and they determined that the oil cap for the four-wheel drive failed. the cap was replaced at the cost of $5 and the contact was advised to never place the vehicle into four-wheel drive. one year later, while driving at an unknown speed, the contact heard a humming noise coming from the front of the vehicle. she was able to safely drive the vehicle to her destination. the vehicle was taken to a local repair shop and the technician determined that the front differential failed. the repair would cost $2,000. the vehicle has not yet been repaired. the contact called the manufacturer and was informed that because the vehicle did not receive regular maintenance from a dealer, no compensation would be provided towards the repair. the vin was unavailable. the failure mileage was 64,000 and current mileage was 81,000. | |||

| I own a 2004 chevy trailblazer with 56k mileage. in december 2008, the speedometer stopped working. i would be at stop, and the needle showed 80 mph. i brought the car to the dealership right away and they told me that the cluster needs to be replaced - but they needed to order the replacement part. i finally got it fixed a week later and it cost me approximately $525. now, for the past two weeks, the engine had suddenly shut off in the middle of driving. the reduced power & check engine lights came on. both times, it started back up after i parked it, turned off the ignition, and re-started. but after the second time, i brought it in to the dealership. i had to have the accelerator pedal replaced. cost me approx $360. these two issues are very concerning with me because if i were driving at higher speed (65mph) in the middle of the highway (instead of 30mph around town), i could have died from contacts with other vehicles because my vehicles stopped functioning! *tr | |||

| Purchased new trailblazer in may 04. when vehicle had approximately 3,000 miles on it, i started getting a rattle or loud buzz when accelerating at approximately 25 per hours just before the vehicle shifts. occasionally, the shift if jerky. the vehicle has to be warm and the rattle or buzz first manifested itself after i turned right and accelerated from a stop. when warm, this sound is repeated almost every time i turn right and accelerate. when warm is also occurs when i just accelerate from a full stop. occasionally, it will also occur after a tight left turn. i reported it to the dealer and they told me the computer did not show anything wrong. on the second trip to the dealer i reported it again. still no fix. the noise is very annoying, but i cannot tell that it is doing damage. i certainly would not have bought this vehicle if it made this noise on the road test. i am estimating the rattle or buzz sound has occurred at least 75 time to date. *nm | |||

| Last summer, my vehicle started stumbling at speeds greater than 50mph on the highway. i had my vehicle serviced several times, without the issue being resolved. i have had the throttle body replaced, tune-up, map sensor, air intake sensor, fuel system cleaned, fan clutch replaced, still had the stumbling problem. approximately 2 weeks ago i was driving home on the highway, when i heard the engine rev up very high, but i wasn't going any faster. i then pressed on the gas, the engine raced, but i was just coasting. i was able to coast off the highway to the median, thank god nobody was behind me. i also thank god i didn't have my family with me. the mechanic said, that one of the gears inside, the tranny was broken, and the pump had shattered. i would hate to see this happen to someone, and they can not get out of the way, someone could get killed. *tr | |||

| I have transmission problems with my 2004 trail blazer i first noticed it when i was driving down the road at 55 and all the sudden it was like the vehicle was put in neutral and i pulled to the side shut the vehicle off and tried to start again and it took off fine like nothing was wrong. then a day or 2 later the same thing happened so i had it towed to the garage. they told me my transmission was bad i was shocked with only 58,000 on the vehicle they showed me the dipstick was rusted right off and asked me what happened i then asked them what happened. so long story short they wanted to charge $3000 to replace because the warranty ran out at 36,000 i refuse to pay when there should be a recall for a problem they admit they have. and to think the government or should i say we the people just bailed this company out as far as i'm concerned if they are going to make junk let go bankrupt. *tr | |||

| Both issues occur daily: apparent transmission problems...vehicle cannot seem to get in gear when cruising anywhere from 40 - 70 mph. it bounces back and forth between gears - not normal driving conditions. multiple trips to 2 different gm dealers has exposed no problems, as they cannot replicate the problem. they must not have driven the car at those speeds as it does it religiously. like many other complaints listed here, and throughout searches done for 2004 trailblazer issues, my tachometer & speedometer are faulty. they do not work properly... at any time may show 8000 rpms or 100+ mph when sitting at a stoplight, or resting at 0 rpms and 0 mph when cruising on a highway. this is dangerous, and gm needs to fix this problem asap for models experiencing this issue. i'm very disappointed there has not been a recall - my family has always been owners of gm vehicles...but will be no more. *tr | |||

| We took our car on wednesday 5/14 to superior chevrolet in cincinnati oh because on tuesday evening the transmission felt like it was starting to slip and not driving correctly. the dealership contacted us on thursday 5/15 to say they were waiting for the warranty representative to come out and give approval before it could be repaired. on friday afternoon, we were advised the claim was denied because there was water in the transmission. the service manager said it was due to a gm defect with the dip stick - the way it was positioned allowed water to get into the transmission and rust, so the warranty was null and void. the service manager said he spoke w/his gm rep and they would agree to do us a favor and split the cost of the new transmission - $1200 still out of pocket for us. when we pushed back and asked why we would have to pay anything, they refused to answer - just told us to fight it with our warranty company. i've been researching online to figure out how to fight this and prevent other people from suffering as well. if it's a gm defect in the way the dip stick is positioned, the consumer should not have to pay for the damage caused by the defect. any help you can provide would be greatly appreciated. the car is a 2004 chevy trailblazer with a full extended warranty, but it does specifically state it's void if the problem is due to water. after reading on several chat rooms, there seems to be many people with this same issue. *tr | |||

| I have a 2004 trailblazer. i had taken it to the dealership service center on several occasions because of issues with it. the service engine light came on all the time. it would rev up the rpms for no reason and make a weird sound. it would not go into 4 -wheel drive or out of it like it is supposed to. and other things. i had it checked, and they said it was all fine and they couldnt duplicate the errors. however, subsequently, the transmission has gone out 4 times in the last 4 months. i have had it replaced 3 times. it is now at the transmission shop and they state that there is a problem with the engine has too much travel to it front to rear. the crank shaft specifically which is allowing the torque converter to pull away from the front pump and break the rotar assembly in the front pump of the transmission. this is getting expensive and frustrating. are there any other people who have the same issues or is there an issue with the crank shaft? could it be the transmission is built wrong? this is rediculous!! i have only 70,000 miles on it. why would i buy chevy products if they continue to fail at such low miles. *ak | |||

| We bought a 2004 chevy trailblazer brand new. we had all scheduled maintenance performed. then in december 29th of 2006 in the evening we experienced a loss of the transmission in third gear. we were trying to merge onto a highway and were almost rear ended by a semi-tractor trailer truck. i quickly pulled off to the break down lane to avert an accident. it has been roughly been six weeks since we dropped the vehicle off at a authorized chevy dealer. our extended warranty wants to rebuild the transmission. the chevy service department wants to replace it. they are at a stalemate. this vehicle had only 68000 miles on it. *jb | |||

| We bought our 04 trailblazer used about a year and a half ago. it was owned by enterprise before and therefore already had 30000 miles on it but we knew that it was maintained well. it is now at 71000 miles and we have done all recommended maintenance. yesterday, while on the interstate the transmission lost third gear and above. this was dangerous but luckily i got off of the interstate with no incidence. this morning we took the truck to our local and trusted mechanic who determined that the transmission was shot. he called jasper to get a price on a new transmission and during that conversation, jasper informed him that they have done 15 upgrades to this particular gm transmission and that even gm is buying replacement transmissions from them. i think that gm should consider some type of recall on the transmissions due to the obvious amount of problems they are causing. needless to say.. my warranty is expired and i have to shell out $3000 to repair a 3 yr old vehicle. *jb | |||

| I own a 2004 chevrolet trailblazer and the transmission recently failed, due to causes unknown. this concerns me because i only have 54,000 miles on my vehicle and it has received all scheduled maintenance. also i've done some research to find out that is a recurring issue starting in 2002 with the trailblazer. i am going to contact chevrolet for repair but my warranty is expired and i am sure is will have to pay for all repairs. *jb | |||

| 2004 chevrolet trailblazer (v6). vehicle suddenly shifts itself into 4 wheel drive low gear without warning and without any action by the driver. vehicle was brought to authorized repair center and dismissed as driver error. shifting any vehicle into 4 wd low requires a definitive action by the driver of the vehicle. an action that the driver would know they performed. this is the 3rd such incident with gm vehicles my company has had. all dismissed as driver error. investigative action needs to be taken at some level. our local dealers and repair centers don't seem to be concerned. *nm | |||

| The vehicle switches from 2wd to awd on its own. this causes the vehicle to klunk and buck. it almost feels like someone is hitting the vehicle fom behind. this happened several times before we figured out what the problem was. vehicle was repaired at the dealership. this was only one of twenty-one failures i have experienced with this vehicle since i purchased it in may of 2004- not to mention my severe back pain that is caused from the driver's seat. i have owned 9 vehicles, and have never witnessed such poor quality in a automobile. i am seeking a buy-back from gm.*ak | |||

| When accelerating from a stop drive train hesitates and engine comes to a near stall, and then accelerates. this does not occur on every start, randomly. took vehicle into dealer who stated that it was normal for the type of drive train . then the dealer reprogrammed the vehicle. after one day of driving the problem has begun again. this hesitation is very dangerous crossing traffic and in intersections.*ak | |||

| The vehicle has stalled out 3 times in the past month. check engine light came on and then reduced engine power light. we could only go 10 mph. thankfully we were in a residential area and not on the freeway. dealership said it was a faulty accelerator position module and the pcm needed to be reprogrammed. lucky us we are over in miles and this is not covered by the warranty. *nm | |||

| POWER TRAIN - TRANSFER CASE (4-WHEEL DRIVE) | |||
| 12/18/2007 | 45000 | 2 | 07/07/2004 |
| 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. *tr | |||
