2017 Rear Diff Problems?
Do the 2017s have any known rear differential issues? I have a 17 and over the weekend I was going slowly up a steep driveway and I heard something that sounded like I scraped the ground. It happened 3 times in total.

Could it be the "soda can crunch noise"?

I'm still far from convinced that there arent any yet to be diagnosed (or admitted to) diff issues in the 2017. I'm hearing noises back there that I really struggle to shrug off as rocks in the dust shield. The most recent crunch was accompanied by a screech like a tire or a clutch pack locking up and the right rear of the car actually lifted up.

If the car got 'lifted up', it could've been gears coming out of mesh. |

Mofomat, I'm interested in understanding whether you feel like there's considerable drivetrain slop in your car as well, seeing as how we have both experienced the "hop". I've noticed when I am at light cruise or light acceleration, then lift the gas pedal, I get a little "knock" from the back end. Thought it was slop in the driveshaft u-joints, but perhaps it's differential gears with too much clearance loading and unloading.

My diff was replaced under the recall last month (early December). I was going to check if I still had the "slop" after the diff was changed. I only drove her 2-3 times after diff replacement before I put away for the winter. I can't swear to it but I have a vague recollection the slop was still present suggesting u-bolt and not diff related. When I take her out again after the winter, or if a long warm spell, I will update you. |

In my Z4M the rear diff would clunk if you unloaded it a certain way at low speeds. Might not be that abnormal.
OP's issue sounds like the rocks in the brake shield. |
