Have you seen that in writing, other than the warranty FAQ page on Tesla site? Have heard of Tesla alternatively saying it is not to extend past initial 8 year/unlimited warranty, and have also heard of one year/12k miles coverage on replaced LDU

I am ref to the drive unit replacement warranty from Tesla. The original drive unit warranty was 8 years/unlimited miles.

The most common issue is the failure of a seal that allows coolant to leak into the inverter housing and eventually corrode the electronics. This is almost certainly what’s happened.

I wonder if there is some dielectric coolant that can be used in the older S that can keep these drive units from failing while still providing enough cooling performance for the batteries.

Took the car to Tony. Nothing wrong with drive unit. It seems the problem was related to loose ground as in addition to PRND error, there are many other errors related to break light etc. Tony cleaned the connection and asked me to drive around and see the error code will disappear. I will keep you posted.

After driving fine for 6 months, the error came back. We have replaced the speed sensor and wire. It seems the PRND issue occurs after the car idle for few days. The error is attached. Any thoughts ?
