Third battery has failed - need advice
- Thread starter jonandmel
- Start date
3 HV battery failure, 5 LV battery replacement. Probably some hidden electrical problem. I would ditch the car and move on. A clean 18 model S 100D W/ 55K miles costs $32K. I wouldn't put out $17K on a 2015 with 150K miles. Suspension and motor is probably the next ticket item coming.

To the OP: Sorry you are going through this. As mentioned, the tesla reman packs are really sketchy in quality. They basically take a pack that recently failed in someone else's car, fix up the acute issue, and sell it to you for $16k. It is a huge profit center for them even though the fanboys will say they don't make money on batteries. Show me that math and explain how their net profit on a used battery isn't better than the margin on a new Model3. I digress... Fortunately, it sounds like your two replacements have been under warranty so you haven't 'paid' for one yet.
If you do plan to keep the car and aren't going to a 3rd party, absolutely spend the extra money on a NEW pack. That should get you a full reset on the HV problems. True, the warranty is the same, but the new pack should actually last past the warranty period. A couple of things if you go that route:
1) Check the pack label behind the left front tire and make sure it agrees with the invoice. It should be T23 or T24 and have no 'R' at the end. It should also be 350V. The 400V 90kWh packs are the older cells.
2) Make sure they don't cork you at 85kWh. That is their practice when someone wins the lottery and gets a NEW pack under warranty (sometime they don't have refurbished packs in stock), but when you are paying cash/retail for a 90, they need to give you the full 90. Many SCs are confused about their own policies so shop around.
3) Get everything in writing and take screenshots off the app as you go. It is shocking to consider, but sometimes correspondence that favors the customer can vanish from the chat.
