Really? Fix what? I don't know about other EVs, but I checked the recommended maintenance (every 10K miles) out to 100,000 miles on my Ford MME and it's rotate tires (every 10K) and replace cabin filter (every 20K). That's it. Everything else is just checks.
I have 24K on it and it has cost me zip in maintenance and repairs. Time will tell on future reliability but so far so good. Battery warranty is 8 years/100,000 miles. And, oh, BTW, fit and finish were perfect. I think I can easily keep this car long term with no issues. Plus, it's a blast to drive.
