Transmission failed at 81,000.
Transmission fluid flushed and transfer case fluid serviced at 47,000 miles by Chevy dealer at a cost of $235.00.
Service representative told me that the seal between the transmission and (I believe he said) the transfer case failed and the transmission fluid went into the transfer case.
Caused transmission fluid to be three quarts low from the internal leak.
Even though no fluid ever leaked out of the vehicle, the GM representative said it was my fault because the transmission fluid should have been checked at each oil change.
The transmission failed while I was driving down the highway.
Total cost of GM remanufactured transmission $3,922 installed.

This GM vehicle has suffered from some of the "known defects" by GM. The instrument cluster has been replaced under warranty, fuel pump became weak and been replaced, the actuators that control the airflow into the cabin become flaky and will start blowing hot air out (you have turn off the car and restart-I've gotten good at doing this while going down the road). The final straw with this vehicle - excessive porosity in the cylinder heads (again, a known issue with GM supplier's CasTech heads) allows steady leaks into the valve train and gets mixed in with the oil. It has gotten bad (1 gal/month) and now at 105,000 miles, this vehicle has to go unless GM steps up. TBD.

I've had my Tahoe for 3.5 years and it has never had any problem of any kind-- I've put 78k miles on it. This fantastic vehicle has the most comfortable 1st and 2nd row seats I've ever seen. The third row, although it has lots of padding, does not have very much leg room, it's great for children. The ride and handling are very good. One high point of this sturdy SUV is it's AMAZINGLY EXCELLENT TRACTION. While other vehicles are spinning around and slipping off the road, this vehicle charges ahead with utter confidence. Good visibility is another high point.
Chevrolet offers revised 16- and 17-inch aluminum wheels, and 17-inch all-season tires are now optional on LT models. Other new features include a tire-pressure monitor and Hydroboost brakes that provide more reserve stopping power and decreased pedal effort, according to Chevrolet. A traction assist feature is available on two-wheel-drive Tahoes equipped with a locking rear differential. The trailering package includes a 7-to-4 pin brake wiring adapter. Finally, for added safety, there is now a front-passenger seatbelt reminder.

We're looking hard at the 2015 Tahoes. Had a question about the 4WD modes but can't seem to get the straight answer. Felt it may be better to come ask from people that aren't employed at the dealers...
