“While diving at highway speeds (first at 55mph in may 2025 and then again in July 2025 at 65mph) I got a warning on screen about power loss and a critical failure and that power will be reduced and to stop at the side of the road.

“I was driving yesterday accordingly to the speed limit on a main city street.

I felt completely out of control of my vehicle and I am so thankful I wasn't on the highway and that no one was near me!
