2008 Pontiac Torrent makes a squealing whistling noise

Pontiac Torrent

Hi my car makes a squealing whistling noise when reversing and turning, and sometimes driving. Id like to know what the cause is, and what the repair price would be?



This is one of those cases where you will need to diagnose the issue and then price the repair. There are so many possibilities that actually looking at the vehicle and diagnosing the problem is the better than guessing.

In general a whistle noise sitting still and revving the engine indicates a vacuum leak, it only while driving, it may be a loose or damaged body panel.
