    Recently, an analysis of drive unit failures has predicted that 100% of Model S drive units will fail. Others have pointed out failures in high mileage cars.
    I've set up a poll to try to get some better information here. I'd like to get a snapshot of current mileage and drive unit replacements.
    Please vote in this poll regardless of the mileage of your car and regardless of whether or not you have had a drive unit replacement. We need positives as well as negatives.
    The poll is only looking a mileage and drive unit replaced/not replaced.
    After you vote, you can post to the thread if you wish with the gory details of your production date, mileage and drive unit replacement(s).

    Don't we already have about a dozen polls like this? Also, this doesn't change the sampling. You're still sampling a very small subset of Tesla owners, and that very small subset ALL have two things in common -- they have an interest in Tesla and they're on TMC. For a random sampling, you want diversity.

    Yes, there will be bias... probably towards people who have had their drive units replaced since they are more likely to post on TMC and to vote in this poll.
    I do hope to get responses from high mileage people who have their original drive unit in order to gauge the veracity of the "100% drive unit failure" claim.

    80k miles, been through 3-4 drive units all for the thumping sound. Could probably get another replacement due to high pitch whine when gunning it.

    The third drive unit lasted less than one month -- thump was not fixed.

    Sounds about right. Most people don't need a drive unit replacement...
