So a while back, I was rear-ended while stopped in my Model X at an intersection, while an ambulance tried to cross. The damage was relatively minor, but given that the bumper contains a lot of tech, my insurance estimated the repair at 70 hours of labour. Since there wasn't a "Tesla certified" body shop nearby, I was sent to a body show that is currently "in the process of" certification by Tesla. Well, it's now been over 50 days since this body shop has had my vehicle. Not only are they 3 weeks over on their repair timeframe, they left my Tesla unplugged and outside in the bitter cold of winter over the holidays. The battery fully discharged to 0%, stayed like that for a few days, and then I lost connectivity through the app. The car stood in temperatures averaging -20 C (-4 F) for a week and a half, fully discharged. When they got back to work after New Year's, they had to pop the frunk and jump the secondary battery. I had warned them several times about the risks of fully discharging the battery. To make matters worse, a week later, they did the EXACT same thing! I'm very worried that they've damaged the battery on my less than one year old Tesla. I've tried contacting Tesla Support, but so far the only helpful thing they've said is they can run diagnostics on the battery, remotely. I haven't been able to get any further reply more about this (i.e. what data they would get, etc.). I've also contacted an attorney, and am exploring seeking damages. I'm wondering whether anyone has had a similar experience? Or more importantly, how can I determine the battery's health? I'm also worried that any potential damage might not show up right away, but only become apparent months or even years down the road. Any thoughts would be greatly appreciated! Thanks in advance.
