I also had to have the actuator replaced on my gmc 2004 truck. It was blowing hot when the A/C was on and should have been cooling. It was not cheap either, it also had to be recalibrated in the computer system. I didn't expect that to happen to a new vehicle.
Reduced engine power, this has happened about 7 times. When this happens the engine shuts down to 1500 rpms maximum. Took to dealer, they told me that it was the throttle body valve and actuator assembly. This part was replaced at a cost of $481. Within two weeks the same problem has happened twice more. This is dangerous when traveling in traffic.
