I have a 2021 SLT with 8650 miles on it when it would not start and gave me a code that I was using a wrong key. Had dealer tow it to the shop and after two weeks was told the ECU (electronic control unit) needed to be replaced. Apparently not all shops have the diagnostic equipment to readily diagnose this type of failure thus the two week delay. Hopefully parts will be available in short order. I'm told patience is a virtue. Careful what you pray for.

Wondering if anyone else had similar issues with their Spyder?
