Q: Abnormally loud brakes, acceleration hesitation, & liftgate won't open automatically

1.When I was putting on the brakes, they were abnormally loud. I then took it to the dealership where they told me that the rotors and brakes should be replaced, which they did. But… the loud noise still exists! This is the third time I have had the rotors and brakes replaced since purchasing my SUV.

1. Another thing I want to tell you is that while I was trying to accelerate, my SUV hesitated and slowed down. So back to the dealer I went. I was told that my vehicle had not failed, but that it had been calibrated that way.

2. Also, the liftgate wouldn’t automatically open and I had to manually open it. But when I was at the dealership, they couldn’t duplicate the problem. It opened automatically for them. Can you tell me how to fix the loud noise, acceleration hesitation, and the intermittent malfunctioning liftgate?
