The failure pattern owners describe
Owners describe sudden, complete motor shutdowns occurring without warning during highway and city driving. The vehicle loses all power and throttle response while interior electronics—audio, lights, hazard system—remain functional. Dashboard warnings read "Engine Control Error," "Drive System Control Fault," or "Electrical System Error." Most incidents occur between 15–55 mph; owners have been stuck in fast lanes, left shoulders, and traffic, forcing emergency stops. One owner reports being locked inside the vehicle during a failure on the freeway.
Power cycling—turning the vehicle off and back on—restores normal operation temporarily. The fault has recurred 3–7 times for some owners. Dealerships have performed software updates and 12V battery replacements without permanently resolving the issue. When brought in for diagnosis, dealers cannot retrieve stored codes or reproduce the failure, leaving owners unable to pinpoint cause. One owner notes the problem occurs after charging or idle periods; others see no pattern. No warning signs precede the failures.

What owners are reporting 2 most recent
While driving, shortly after a turn, the electric motor has a fatal error resulting in complete loss of power while driving. The car has to be stopped in the middle of the road and powered down and then turned back on. This clears the fault but the problem has occurred 3 times within a month resulting in me not driving it anymore.
