How many pre-facelift owners here are on their original Drive Unit?

[swegman]

2013 P85 with about 65K miles on original DU and (capped) battery.

2014 S85 54,000 miles, with original drive unit.

Late 2014 S85
103k km, original drive unite

What is a "capped" battery? We have the same spec car and I am unfamiliar with that term.

Just curious, how many here have cars that are on their original drive unit? Pre-facelift cars only. Please state year and mileage. Thanks

November 19, 2015
38,000 mi.

April 2015 build S85D, 70K miles, both drive units still original.

Just curious, what conclusions are you attempting to draw from these data points?

The original pre-late 2014 big rear DU’s had quite a bit different internals. I’m just curious about how many are left, and how far they went. No agenda, just wondering.

Sorry, didn't mean to imply a hidden agenda. I was thinking more about how you would go from a number of self-reported, er, "survival stories" to a statement about statistical reliability. Also as someone pointed out, a number of us with dual-motor cars responded but we weren't meant to.

I’m not after a super accurate estimate. I was simply curious. I also thought about the responses from dual motor cars before I posted, that’s why the title states “unit”. It’s no big deal that owners of D cars post, as I said before, it’s not really a scientific experiment.

What is a "capped" battery? We have the same spec car and I am unfamiliar with that term.

Firmware version 2019.16.1 limited the voltage that each cell in the battery can be charged to on the 85 kWh battery. A normal cell is charged to 4.2 volts at 100% SOC. The software update reduced the maximum voltage that each cell will charge to to about 4.09 volts. This is called capping. As a result of the capping, a battery pack that may have had a range of say 255 miles prior to 2019.16.1 may only have a range of say 225 miles after the firmware update. Not all 85 kWh batteries were subjected to the capping. But many were.

There is a huge discussion of this on TMC (over 6,000 posts so far), and a class action lawsuit has been filed over this.

Dec. 2014 build P85D with 43k miles. Original DUs. I appreciate this inquiry because from what I've seen in the news and YouTube, there was a resonating conclusion from auto "gurus" saying that the pre-2016 cars were plagued with drive unit failure disaster.

2015 85k still og.

2013 Model S 85. Still on the original drive unit.

But mine only has 36,000 miles.
