2017 MS remaining battery and drive unit question

[SudokuJW]

I’m looking at purchasing a used 2017 MS P100D
It is a 1 owner car that was traded in to dealer.
I’m trying to determine remaining battery and drive unit warranty.

Tesla won’t tell me because I don’t own the car.
The dealer does know and says carfax says it was placed in service March 2018 so add 8 years
However recurrent report says the battery has been in service since January 2017.

That’s over a year of warranty time difference.

Dealer says the last owner already removed himself as owner so we can’t ask him. And dealer isn’t the “owner” so Tesla won’t tell them.

How can I get to bottom of this?
Which do I trust
Recurrent or Carfax?

I’m afraid I won’t know actual answer until I own it and by then it’s too late.

Look at the manufacturing sticker in the drivers door jamb. It will have a month/year production date on it. In the absence of concrete information that’s the only number I’d depend on.

 

[SudokuJW]

Build date and in service date don’t necessarily correlate.
It my understanding with all other cars the warranty starts with in service date

 

[SudokuJW]

I guess build date would be worst case.
Which could help.

 

[ucmndd]

Again, in the absence of concrete information the build date is the only one I’d depend on.

If you can ask the dealer to take a photo of the battery sticker then there are two numbers on it. One is part number and another is serial number, first two numbers of that serial number (which starts with letter T) are production year and the frollowing letter corresponds to a month of it. So A is January… Hope this helps a bit.

Nothing on the battery sticker is going to show anything definitive about the warranty term.

 

[KalJoMoS]

True, but OP was looking for certain date so if battery would have been replaced later than the car have been produced, then it tells what kind of warranty it might have.

 

[SudokuJW]

No recurrent is showing the battery as being in service longer than the car has been per carfax

Recurrent shows battery service date January 2017
Carfax shows car first in service March 2018

I’m still not following. Even if the battery was replaced under warranty, nothing changes or can be gleaned about the effective dates of the warranty.

 

[SudokuJW]

Well got a picture of build date:
august 2017

so there is no way recurrent can be right about a battery in service date of January 2017

 

[DavidP75]

Battery manufactured Jan 2017 and then put into the car when manufactured Aug 2017
In service Mar 2018

These dates all seem plausible. As mentioned before, warranty starts at in-service date which would mean Mar 2026 expiration. Carfax has usually been accurate for me with past used car purcahses.

 

[SudokuJW]

Here is what recurrent shows:
Implying the warranty started in January of 2017 not just simply that the battery was built in 2017.

 

[ucmndd]

I have no idea how Recurrent could get that info in any programmatic way.

In 2017 I believe the warranty terms did say it started when the car was registered and placed into service by the first owner.

That did change at some point - the current warranty doc says the clock starts ticking as soon as the vehicle is placed “in service” by anyone - including Tesla using it as a loaner, demo vehicle, etc.

 

[SudokuJW]

Sure but in this case impossible to be in service in January if it wasn’t built until August.

So just a bit of follow up.
Bought the car, and when the ownership transferred I was able to determine CARFAX was right.
Battery and drive unit warranty are good through march 2026.

Not sure what recurrent was looking at for its warranty projection but it was off by 14 months.
