Selected complaints filed with NHTSA by 2004 Chevrolet Tahoe owners, lightly cleaned up (personal details are redacted by NHTSA).
My Tahoe has the New Process 246GM transfer case. They have a known issue called pump rub where the pump is to close to the magnesium shell, and rubs pin holes in the shell which causes fluid to dissipate over time causing the transfer case to run dry burning it up. I've had a mechanic check it out and there was no fluid in the case, and now I have a transfer case that's burned up. I've called a transmission shop, and they told me it was a common issue. I would like for general motors to correct this issue
Tl*- the contact owns a 2004 Chevrolet Tahoe. While driving approximately 25 MPH on normal road conditions; the vehicle automatically shifted into four-wheel low gear without assistance. The driver pulled over to the side of the road. The engine was turned off. Immediately, the engine was restarted into two-wheel drive. The vehicle was able to resume normal operation. The failure occurred intermittently. The vehicle was taken to an authorized dealer for diagnostic test. The failure was due to the four- wheel drive switch module and the encoder motor transfer case actuator. Both components were replaced. The vehicle was taken to the authorized dealer on five separate occasions for the identical failures for which there were no resolutions. The vehicle service warranty expired at 36,000 miles. The manufacturer was notified of the malfunctions. The failure mileage was 27,000. …
I own a 2004 Chevrolet Tahoe. I have found that when the key is in the accessory position, you are not required to use the brake to shift out of park. My 18-month old son discovered this while we were cleaning out the truck and it started to roll down the driveway. I contacted the dealer to see if there was a recall or fix and found that there was not. I found out that this is actually how all tahoes since 2003 are programmed to work. This behavior is not consistant with the other key positions and I feel is a saftey hazzard. Luckily no one was injured in the discovery of this. I would like to see someone follow up with GM to get this resolved before there are injuries or deaths. I would also like to see some follow up with me as to the outcome of this complaint.
I have a 2004 Chevrolet Tahoe. At 59,000, a pinion seal leak was discovered. I took it the next day to the Chevrolet dealer where I purchased the vehicle new. Upon evaluation, it was determined that the leak had resulted in excessive metal friction in the gears, requiring a complete overall. There is no warning system for low differential fluid and leaks are not visible from the ground as any fluid normally blows off while driving. The seal on the rear axle pinion, which provides power to the rear wheels, could leak fluid, causing the wheels to seize and lock. Note that GM has recalled many similar models, but not the Tahoe at this time.
Dt*: the contact stated while the vehicle was parked with the parking brake was engaged and the keys removed from the ignition, the contact opened the front left door to retrieve an object, when it began to roll backwards down the driveway. The vehicle continued over the embankment with the contact and crashed into a tree bring the vehicle to a stop. The contact was ejected from the vehicle prior to hitting the tree. Injuries were incurred to the right elbow. The service dealer and manufacturer were notified. An independent inspector was sent by the manufacturer to investigate. The results of the manufacturer inspector were not shared.
Tl* the contact owns a 2004 Chevrolet Tahoe. The contact stated that when shifting to drive or reverse, there was no indicator that displayed what gear the vehicle was activating. Often while in reverse, the vehicle would move forward. In addition, the gear shifter would sporadically shift out of reverse. The vehicle was taken to the dealer several times for the failure. The dealer replaced the gear cluster wiring harness but the failure was not corrected. The gear indicator continued to fail. The approximate failure mileage was 5 and the current mileage 59,897.
I am starting to feel a clunk in the transmission of my 2004 Chevy Tahoe z71, the gears wine a little but there is this constant clunking sound. I have met a lot of people and they all have the same problem. I know I am not far from having no 1st and 4th gears etc.. I bought the SUV used and I took it to the Chevy dealer for a bumper to bumper inspection. I do not drive hard. The people I talk to said it is a common part and there is actually a bulletin out on this. Chevy will not have it but other transmission shops do.
ABS light came on along with a loud hum and rattling from front tire area. Had to get the hub assembly replace. This happened around 90,000 miles with the front passenger side tire, and around 130,000 miles with the front driver side tire. Both mechanics I brought it to said this was a common problem for my type of vehicle. They also mentioned that when this occurs the entire wheel could fall off and result in a major accident if traveling at high speeds.
1)events leading up to the failure: during normal city driving, came to a red light and full stop. When it turned green, the brake pedal was released but the vehicle wouldn't move forward. 2) the vehicle wouldn't move and as a press the gas pedal, I could hear the engine rev up but not change, the vehicle wouldn't move. 3) the transmission finally engaged and the vehicle started moving forward about 3-4 seconds after the initial trial.
While driving 60 MPH the vehicle's rpms revved up. The vehicle would not accelerate any higher that 15 MPH. The dealer inspected the vehicle then drained then drained the transmission fluid. The dealer indicated that they needed to replace the transmission. They didn't indicate why they were replacing the transmission or what caused the failure.
