2004 Chevrolet Tahoe LS Rwd 4dr SUV (4.8L 8cyl 4A)
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.
