100% drive unit failure rate??

[qwk]

I had total DU failure at 49k miles. Encoder error, with red PRND. Car wouldnt move. Current revision Q unit is at 34k miles with no noise.

There most definitely have been total failures of DUs which were installed or manufactured after November 2015.

Looks like Tesla Bjørn's Model X (2016 model?) drive unit has joined the choir invisible, too.

Happened while he was livestreaming:

But Tesla customer service helped him quickly.

Do you have a link to someone needing to replace a -Q drive unit?

Adding another data point here.

Model S P04xxx just had a motor failure. Managed to get home, but now car refuses to engage the motor. No warning signs such as reduced power, noise, etc. Just up and died.

Currently working to source a replacement motor (thank you @AutobahnEV ) since this car is not supported and get it installed.

What is code:
BMS_w035_SW_Isolation
BMS_w151_SW_external_Isolation
???

 

[Volodey]

It's Battery Contactor or Main Cable?

 

[Snerruc]

On my second S. Neither one has ever been in for service.

 

[Cory151]

Inspire of all the Ludicrous acceleration, neither of my performance model S have never been to service other than for the airbag recall fix.

I just had a total RDU failure, with my late 2014 P85D with about 65,000 miles, stranded out in the boonies. PRND all red, with a service required message. I could shift it into D, but as soon as I stepped on the accelerator, everything went red and locked up. Luckily a forest service ranger station let me use their landline, which I assume went via a satellite link, to call Tesla service. They were there in 3 hours and towed me approx. 100 miles to the service center, where it is currently getting a new RDU. Roadside assistance is wonderful, great to have if needed.

Anybody know what the newest car is that had a drive unit swapped because of noise?

Ill chime in here. I have a Nov 2016 delivery model S60 Just had motor and axles replaced at 49K motor had roaring sounds from 60mph to 80+ mph. New DU has very distinct high pitched whine ONLY on decel fro EXACTLY 25mph and below. I suspect the "New" DU is a rebuild, but not a good one. original failure was axles leaking

A question by a newbie for those in the know: If a drive unit fails in a dual motor S can the car still drive/limp on the remaining unit? I have a 70D and the next service centre is 400km away. Would Tesla pay for towing if it’s the drive unit and in the 8 year battery/ drivetrain?
Thanks!

So they replaced it with a T version, wow, had no idea they were up so high in the revisions.
