If you don't get it looked at, you will drop a rear diff like I have recently.
Just driving normally and then bang.... massive shudder from the rear.
Do yourself a favor and check if there rear diff is leaking oil from the drivers side drive shaft. If so, then it's only a matter of time till you cop it.
To prolong the life of the diff, disconnect the sensor to the rear diff(there is a plug that you should be able to get to - this will keep the car in "FWD" mode, not really FWD, but won't push excessive power to the rear.
If the car is under warranty, take it back asap.
I'll be honest, I gave mine 1 too many 5k launches and that's why i think mine broke. Also, I only replaced 2 tyres on my car, when i should have done all 4. Those 2 things and a combo of my rear diff bolts always coming loose caused it to stuff up.
Anyways, don't drive around with your handbrake up 2 clicks- it will only wear ur rear pads!
