Owner report 11592833 · 2024-06-06 (June 6, 2024)
Car stopped abruptly on a two lane highway and a flashing warning came up that said electrical failure. Car jerked to a stop. Had to be towed to the dealership. Very dangerous. A friend has the same car and it happened to him twice. The cars do not need to be on the road until absolutely corrected. Needs a recall.

On multiple occasions, the vehicle has suddenly lost power and completely stopped while driving on the freeway without warning.

These failures created extremely dangerous situations, as the vehicle lost the ability to maintain normal driving speed in active freeway traffic.
