When turning, I hear a thumping, grinding or chatter noise from the rear differential and the car slows. Mechanic changed the differential oil and found metal shavings/particals. Noise was not there for about 80 miles but has returned. I have to get a new right differential. I checked on the forums and this seems to be a common problem, one owner has had to replace his differential 4 times.

The manufacturer was notified of the failure and the contact was provided a case number; however, the contact was still awaiting a call back. The failure mileage was 69,605.

Unlike other vehicles with the same defects, the contact's vehicle is not a part of the recall.

On a few occasions, the car shifted into neutral on its own after being in the drive gear. This is quite dangerous and unsafe. There are no warning lights or indications. I noticed this problem a few months ago and it has happened a handful of times. I have don’t extensive research on similar problems and have only found forums with other gla drivers experiencing the same problems. There is no recall that I can find regarding this issue. The dealer is also unaware of this issue.
