Checking in at 190,000 miles. Just had the rear drive unit replaced with a reman unit. Car is still great!
That’s some exceptional mileage! How much did the drive unit replacement cost you? How did it behave before?

Did you need to replace the battery? Same question about the drive unit cost. Have you had any other repairs?

@Big Earl seems to not be responding to the query so I’ll let you guys know it cost him about $3500 to install the refurbished rear motor, they wanted to charge him $1500 core fee to take his old motor, but he went back later and told me they didn’t end up charging him for it.
The issue that caused the need for repair was an isolation error. A certain amount of electricity was bleeding through and was detected by diagnostics, it let him drive, but he had a 17 hour trip home and the SvC didn’t think it would continue to let him drive all the way home.

A few times a week I drive 120 miles round trip (like your commute) to go surfing, and FSDb does 99% of the work. I can't imagine doing it in a car that doesn't drive itself.
Can you elaborate on why you do that in the Prius instead of the Tesla?
That sounds like the happy ending of many books in which a spy or lawyer becomes a teacher. Congrats on a smart decision.

The Prius can hold up to 50k/yr. With the Tesla, that could result in a new battery or a drive unit in two years for another 10k to 20k. That's more of a risk than I'm willing to take right now. We need more data on high mileage M3 and MY to see how the drive units and batteries hold up. There are too many stories about needing replacements.
$3,700 out the door for a remanufactured drive unit. It performed like-new right before it started throwing error codes for low high voltage isolation and went into limp mode, and it performs the same with the new drive unit.
Still on the original battery, which shows around 275 miles of rated range at 100%. Other repairs include the DC fast charging contactors last winter and the AC compressor early on when the car was under warranty.

2018 LR-RWD
70,656 mi
Original motor and pack.
Charging: 13.2% of charges done on superchargers, remaining 86.8% on L2 (240V at 40A).
Range: TeslaFi's estimating 269.31 mi for a full charge, which is below the fleet average of 286.11 mi. Personally, I think its a non-issue. The relatively low distance displayed v. SOC isn't necessarily an indicator of actual battery degradation--its (more) likely a symptom of the BMS going out of calibration. If the low range is the product of a truly "dead" cell I'd expect to get a BMS fault code (not unlike the BMS_u029 errors that've been cropping up on some Classic S's). Not really worth going thru the effort to recalibrate the BMS or even charge the car to 100% to see what the "actual" distance display value. Personally, I just keep the range display in percent mode and enjoy the car.

Update at 137,922 miles. Rear drive unit replaced under warranty with no cost to me. Original battery and have not perceived much loss in range at all. Love the car still.
Thanks for sharing! Sounds like the rear drive unit is a common replacement item for this model. Do you know at what mileage yours got replaced? What error codes did you get?
