Hello everyone,
I've got a concern about a high-pitched squealing from the back of the car when I step on the accelerator. It's not constant, but I can catch it by pressing more or less. The sound is absent in neutral, but is present when accelerating with the pedal and with cruise control.
-does anybody have any experience with this or have any ideas?
Thank you!

 

The only thing I can think of is maybe your handbrake isn't fully disengaging. Unless I am not comprehending what you are trying to say.

 

Might be your belts. Take your car in to the dealer.

 

Check the tread and psi on your rear tires

 

let that pig outta your trunk
