| 2004 tahoe, when starting out engine loses power and readout displays ( traction active ). first time happened fall 2007. dealer could not find problem but did a download of software, did not help. over past month does this one or more times daily. took back to dealer and they said not sure what to do, may have to drive until it will no longer run before they know what to fix. this may turn into a safety issue if it stops and someone hits me from behind. i seen on your complaint section this has been brought up at least once before. *tr | |||

| 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. *tr | |||

| In 2006, i would have intermittent problems with my 2004 chevrolet tahoe. when trying to accelerate from a stop, the traction active display would light up and the vehicle would lag and not accelerate. i took the vehicle to bernard chevrolet in libertyville, illinois, and they advised me that i should bring it back when the problem occurred regularly. in 2008 the problem began to get bad, and the tahoe would lag when i tried to accelerate from a stop and the traction active light would come on. this happened at least once a day on my four mile commute to work. on two occasions i was almost involved in an accident due to the lagging of the vehicle. i brought the car into libertyville chevrolet (the dealership that replaced bernard chevrolet after they went out of business), and the vehicle was kept over night. they scanned it and found no problem codes and then they installed an updated program and it tested okay. i paid $115.00 and then as i exited the parking lot of the dealership, the tahoe lagged as i tried to accelerate and the traction active light came on. i looked at my odometer and it read 38,746 (came in for service at 38,745), however, when i looked at the receipt i noted that the service department had put the mileage out at 38,748. the vehicle was obviously not test driven after the service, however, they tried to make it appear that it was. kevin p #475 was the technician at libertyville chevrolet. the $115 charge was reimbursed, however, chevrolet has made no offers to fix this dangerous condition on my vehicle. the problem has been the topic of many problem auto chat discussions, and apparently the problem is related to wheel sensors that prematurely corrode on the tahoes and yukons. i have managed the problem by letting of the accelerator when the problem occurs, and this apparently disengaged the malfunctioning traction active mode. this is a dangerous problem that shouldn't occur on a $43,000 vehicle with 38,000 miles. *tr | |||

| Transmission does not always downdhift into first gear when coming to a complete stop and downshifts into first hard after acceleration of vehicle speed increases do to second gear not moving vehicle. also, when shifter lever is manually placed in first gear tranmission does not remain in first, will automatically upshift into second gear causing towing conditions to become harder.*ak | |||

| 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.*ak | |||
