2016 P90DL - New Main Battery Time?

[Rob J]

Hi all,

I have a 2016 facelift Model S P90DL, it's done nearly 77,000 miles. I feel the main battery degradation is pretty bad and that I might be bordering on meeting Tesla's requirements for a warranty replacement.

I did a trip today, left on 100% charge straight after charging had stopped. I got home with 10% battery, did 165.8 miles and crucially used only 57.8kWh.

I appreciate this isn't overly scientific but do you think I'm at the point that it's worth a try with Tesla? There are no faults as such, just perceived degredation.

Thanks in advance,

Rob

Your usable seems to be in the ~68kWh range (factoring 90% with a 5% detractor for drive losses)

Pretty bad but unfortunately probably wouldn’t qualify for replacement.

Your car doesn’t have a warranty for degradation at all, only failure. So there is no threshold at which Tesla will give you a new battery on those grounds.

Taken from Tesla's website:

Battery and Drive Unit Limited Warranty​

The Battery and Drive Unit in your vehicle are covered for a period of:

Model S Model X

8 years or 150,000 miles, whichever comes first, with minimum 70% retention of Battery capacity over the warranty period.

It's the 70% retention I was questioning.

 

[ElectricIAC]

New was somewhere around 82 usable if I remember correctly so you’d have to be down to ~58 for that to kick in if that was the case.

And I believe that started with the Model 3 since even our Raven MX has the 8yr unlimited miles battery warranty.

That warranty policy does not apply to a 2016. The battery warranty back then was ‘8 years unlimited miles’. Degradation is specifically not covered.

That warranty applies to new cars. Not yours. You have an 8 year unlimited mile warranty with no capacity guarantee.

Damn! Well thanks for the replies anyway chaps. Now I know.

Not related to your question, but how do you have a navigation direction overlaid on the energy graph on the left?? It looks so cool!

You can access the warranty for your car in your Tesla account.

No idea, just have the nav running and then select energy instead of nav using the left thumbwheel. It could just be an MCU1 thing, other than that I don't know sorry.

If your are navigating to a destination and have a display other than navigation selected on the left side of the display, you will get navigation alerts pop up at the bottom as you approach turns, exits you need to take, etc. So for longer stretches where you just need to follow the current road, you will not see them until you get to the next turn at which point the pop-up direction will return.

It's not related to MCU1, does the same for me in my mid-2016 MS90D API that I've upgraded to MCU2. Now it may be related to AP1 or standard autopilot and navigate on AP, EAP, FSD may possibly behave differently.
