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.
2004 Chevrolet Trailblazer transmission complaints
Page 3 of 3: complaints 41 to 62 of 62, newest first, as owners wrote them.
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.
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.
Tl* - sometime in late september 2006, while driving at 65 MPH the transmission began to slip. The vehicle sounded as if it wanted to accelerate, but couldn't. The contact's vehicle continued to have the failure for about 10 seconds. The vehicle also had the same type of failure while at a stop light. While trying to accelerate the vehicle's speed decreased to 5 MPH for about 20-30 seconds. On 10/11/06 contact took the vehicle to the dealership. Dealership replaced the exhaust check valve. On 10/17/06 vehicle continued to have the same failure and the engine light was turning on,. The contact took the vehicle to the dealership where they replaced the oxygen sensor. The contact continued to have the same incident with the transmission slipping and the check engine light coming on. Contact took the vehicle to the dealership on 10/3106, and they replaced the valve body. It continued to have the same incident with the transmission slipping, but this time the engine light was not showing. He took the vehicle to the dealership on 12/20/06, and they stated that there wasn't anything wrong with the vehicle. The contact currently has the vehicle parked at home and does not plan to drive it because he doesn't feel safe in vehicle. *ak updated 2/26/2007 -
While I'm driving the car will just turn off. I can be at a light, turning, merging onto traffic or just sitting in traffic. I've been able to avoid three accident to date. I did bring the car in to the dealer - they fixed it. Until it happened three days later. It happens 6 out of the 7 days a week.
I have had my trail blazer for 1 yr and 1 month. In that time I have had to replace front and back pads and rotors, ball joints, catalytic (sp) converter, and now they just told me I have to replace the head gasket on the manifold. What the hell is going on with this vehicle. I no longer feel safe driving it. The other day the radio just stopped playing and then the service 4 wheel drive light came on.
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.
Transmission went out.
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.
Transmission slips when accelerating such as merging onto a highway. Has occurred at least 10 times. Has been to dealer 3 times but say they cannot find a problem if check engine light does not come on. Has happened intermittently over a year - vehicle has only 27,000 on it.
The rear tires on the consumer's 2004 chevrolet trailblazer wear out every couple thousand miles while the front tires show no visible signs of wear. *nm it was discovered that the vehicle had a bent differential.
Shortly after I purchased a 2004 chevy trailblazer I began to have problems with a loud vibration from the undercarriage. It has been to the shop numerous times but is still not fixed. Recently the vehicle began stalling out at any given time. Dealer could not replicate. Still does it!!! Around the same time my transmission would slip. Dealer could not replicate. Still does it!!! Now I am feeling a lot of vibration in the steering wheel when I turn. Talked to other tb owners and I thinking I will need to replace the struts. What next!!
Dt: the caller said that when she would be at a light the vehicle would stall. She would hit the gas pedal and the vehicle would hesitate before taking off. Engine service light came on/off. On july 25, 2005 dealer checked and reprogrammed automatic transmission control module( PCM). On july 29, 2005 dealer checked and replaced the PCM again , and on august 1, 2005 dealer replaced a 02 sensor. Dealer said they could keep and drive vehicle to see if that fixed the problem . Dealer would not give her a temporary vehicle to drive while she waited for her vehicle to be worked on. Dealer said the 02 sensor was the problem. Would not offer an extended warranty. Dealer will not give her enough money for it as a trade in.
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.
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.
The check engine light and the reduced engine power light came on the first time and the truck had no acceleration. There was a code recorded when service was performed and PCM was reprogrammed. The next 3 times the check engine light came on and the truck would only accelerate if the RPM's reved up to 2, then the truck would move very slowly. The problem they found this time was a faulty ingition switch (2 times) a program upgrade of the motherboard of the truck, and the tork converter clutch module. Windshield wiper blades stopped working during a snow/rain storm.
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.
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.
When attempting to shift gears the gear shift box locked. As a result, vehicle rolled down the driveway. Crashing into a mail box.
The vehicle operated normally until part failure. Transmission pressure cooling line connector not in place properly,caused automatic transmission fluid to spray on hot exhuast manifold, starting a major engine fire.the vehicle was inspected by general motors adjuster, and considered a total loss.no repairs were attempted.
Car has a vibration when the speed is held constant. Been to the dealer twice, they found that all for tires were out of balance. Problem still there, gave one tech ride because they could not replicate, he said it was unusal but he was front end guy, second tech and service manager said it was normal, not sure if they were able to replicate. Was told to bring it back when problem got worse or broke.
On 4 separate occasions vehicle stalled. When this occurred consumer tried to restart vehicle, but it wouldn't restart. Also, keys were stuck in the ignition. As a result, battery was drained. Dealership has replaced automatic transmission shift lock control, battery fuses , programmed the calibration for the engine control module, the starter, and its relay switch.
