I am on my 3rd drive unit now.
First one replaced for noise and failure.
Second one replaced last week (3/2019) for a whine during acceleration.
What drive unit are you on?
What year was your MS manufacturered?

    2014 Model S85, on second drive unit.

    Replaced at 30,000 miles due to increasing noise.

    2013 TMS 85, original drive unit with 67K miles. There's a little noise under light-moderate acceleration between 25-35mph, and a more pronounced noise at >75% throttle, but nothing to be concerned about for now.

    Current drive unit has 173k miles. Ceramic versions haven’t needed replacements to my knowledge.

    Mid-June 2016 build refresh MS90D. Rear drive unit replaced at 32k miles. Front still original and with 43k miles.

    Rear drive issue was described as likely a marginal false fault for CAN throttle overload. GIven it was second repeat occurrence which results in the car suddenly going dead accelerator, coast to side of the road, and unable to shift out of part, service decided to replace the rear drive unit.

    2nd DU. Dec 2013 85. 30k or so when replaced a couple years back. Milling noise at 40ish mph, and during hard acceleration. No noise now, at 53k (I dont drive many miles). Which DUs are ceramic?

    I think they did the change around July or August 2014 if I remember right ... if you have an earlier car with the steel bearings it isn’t a big deal since Tesla will replace your bearings with the updated ceramic ones under the 8 year unlimited mileage warranty! Drive units are now reliable!!

    Sep. 2014 Model S, 50K miles. I'm on my 3rd DU

    Original replaced at 22K miles, low speed whine. Replacement had ceramic bearings.
    2nd DU replaced at 44K miles. Dashboard faults appeared. Diagnosis was an internal fluid leak.

    @ATCRomes

    Look at the paperwork. If the DU part number ends in -Q, then it has ceramic bearings. Per your timeline, it's likely you have a DU with ceramic bearings.

    85D from Dec '15 with 72000 km. The drives haven't failed completely, but at times have very loud whining. Tesla doesn't consider this a fault, but the first approx 15000 km, there was no such noise. Both front and rear units have loud whining. I would never recommend the D versions due to noise. I just wish that teams would develop a fix for this.
