We have had ours for 4 years and are out of warranty. It has 45k miles. The battery mileage has gone down from 262 to 240. Now our computer died and it took 10 days to get it fixed. We were told that if this happens again, we will need a new mother board for 1.2 k, Originally, we had planned to exchange for a new car at end of warranty, but now are waiting for new battery and triple motor. We are not traveling long distance because of covid, but would like to in the fall, but we are nervous not to get stranded if this computer dies. What to do?
