Hi there,
Just purchased a 2015 S 70 and got X-Care. I must say, I am extremely happy with their customer service!
My car threw all kinds of alerts and was inoperable a few days ago. I took it in to the service center (after telling X-care) and this is what they discovered. The prior owner had installed a subwoofer in the trunk and had drilled through the cabin under the front carpets to connect the wiring to the cars audio output. He had also not properly connected the wiring. We had heavy rain the last few days, and the front carpets were soaked and there was a question of water damage in the wiring system.
X-care informed me that the warranty would be voided, as the damage was caused by after market alterations that the contract clearly states are not allowed or covered (I had seen this in the contract but was unaware what the prior owner had done). They did agree to refund me the entire amount I had paid, instead of prorating it (I only had the policy for a few months so difference was fairly minimal but this was still a nice gesture).
The Tesla service folks removed all the after market wiring and determined there was, in fact, no water damage to anything but the carpets. Disconnecting his crappy wiring solved the problem of the alarm codes and the car now runs fine. They also plugged the holes in the floor boards that he had made.
I asked X-Care to consider allowing me to keep the warranty, since the after market alterations had been removed and the car now runs fine. I even offered to restart my 1 month, 1000 mile "no warranty coverage" period. The X-care rep talked to his manager who spoke directly to the Tesla service guys and confirmed the car was now running fine.
They agreed to reinstate the warranty and did not even make me go through a new one month waiting period. While I did have to pay for this service out of pocket myself (only $300), I feel that was reasonable given that the problem was caused by something clearly not covered under the warranty.
Overall, X-Care was prompt to help me start my claim, clear about why it wasn't initially covered but very professional, and then extremely flexible and reasonable in allowing me to reinstate the policy.
I had very little interest in purchasing a used Tesla out of warranty, and would have considered selling the car (for a big loss) had they been unwilling to reinstate the warranty. So, overall , I am very happy with their service
I was also hesitant to use them because of limited info online, but now have no regrets at all!
