Consumer Description

On December 23, 2025 while driving at 50 mph the car displayed an electrical warning and would not let me drive more than 40 mph. When I drove it to the dealer on December 27 (because the dealer said I had to wait until after Christmas ) it would not go over 20 mph. The vehicle has been at the dealer awaiting an ICCU part since December 27, 2025. Over 50 days!
