My 9 month old Ampera has started to develop a squeaky noise. This only seems to happen when I reverse off the drive, which is a slight incline upwards. It sounds like the rear brakes may be rubbing. Anyone experienced this?
My Ampera makes a faint squeaking that I notice when reversing out of the drive. I think it's the brakes catching (slightly). Nothing to worry about - and it's only because the car is SO quiet that I notice it in the first place.
Strangely though, it's fine (and dead quiet) when rolling forward....
Does the sound come from the rear of the car for sure? Reverse only noise is not uncommon for foreign body trapped between cover plate and disc. I would only worry if it could be coming from the planetary gearbox which sounds unlikely if you are suspecting rear brakes. Physical inspection would prove the point.
