My wife’s May 2016 X P90D with 30,500 miles, is now at 207 miles @ 90%. Not good.
Hi all. I have noticed rather extreme degradation of my 90 battery pack on the X (P90D). The car was purchased last March has 24k miles. At full charge was about 255 miles full charge and 90% was 225. Now, it’s 235 for a full charge and 208 for 90%.
This, despite what some are saying, is not normal based on my experience with my 2013 model s (p85+) that is almost 5 years old with 54k miles. Full charge on that is now about 255 and new was 263. 90% charge now 228 was 235 so very little degradation.
Do we have recourse? Basically just deal with it? Does anyone have a story where Tesla actually did anything besides telling you it’s normal??
Tesla owes you a new battery. They will resist but others have prevailed and received new 90 packs. They usually require an NDA to receive the new pack which is why there is so little public discussion. That said, if you do some digging and PMing you can get all the information you need to proceed. The lemon law is the usual starting point. Once you file and Tesla receives notice, they will become much easier to deal with. It can take up to one year to get the new battery and in some cases, Tesla will offer to buy the car back. I would start with your state AG website and research lemon law case settlements. In florida the mediation panel nearly always sides with the consumer. Tesla was ordered to repurchase on MS last year for a noisy AC. Battery capacity loss is a slam dunk. Good luck.
Does anyone know at what % of degradation the warranty kicks in?
That looks correct. My 2016 X 90D charged to 215mi at 90% today. That puts me at 215/.9 = 239mi compared to the original 257. I'm at 7% degradation.I purchased my first Tesla (also my first EV) this past December. Can you guys see if my calculation and assumptions sound correct?
2016 Model X P90D
about 21k miles now
90% SOC = 212mi (December and January outdoor temps in the southeast roughly 30F - 70F)
100% SOC = unknown (never charged to 100% and purchased car used)
estimated 100% = 212/0.9 = 236mi
assume 100% SOC originally was 250 mi
degradation = 1 - (236/250) = 0.06 = 6%
Does that sound right? Did I calculate correctly? My X (purple dot) sits below the red line on the chart attached.
