What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Driving under normal conditions, heard a âpopâ near the rear of the car and within seconds had an immediate loss of power. The dashboard had lit up with âCheck electric vehicle systemâ and was limited to 20 MPH on a 45 MPH road with no safe place to stop.
ICCU failure and fuse, the car became unoperational and needed to stop. The car would no longer charge the 12V battery, and the EV battery would not charge. Hybrid Control Problem Detected at 3,160 miles. DTC P056216
The contact stated that while driving at 40 MPH, the service battery immediate warning light illuminated. A dealer was contacted. The vehicle was taken to the dealer because the ICCU unit needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure.
Within moments, the dashboard displayed the following critical warnings: Red 12V battery icon Red warning: "Stop vehicle and check power supply" Turtle icon (indicating limp mode / low power) Brake warning light â ï¸ The vehicle immediately entered limp mode, then fully lost power within approximately 3 minutes.
Additionally, the contact stated that upon depressing the brake pedal, the vehicle responded as intended after three seconds. The vehicle was taken to an unknown dealer, where it was diagnosed and determined that the ABS module had failed, and a software update was needed. The vehicle was not repaired.
This unintended acceleration, given the performance characteristics of an electric vehicle with 640HP, could quickly place the vehicle and the operator in an unsafe and undesired situation that could result in a crash.
After the recent RECALL, while driving up I almost got in an accident because after upshifting the car, the car accelerated more than I intended, prolonged movement forward that never happened before the recall. This is a very dangerous situation.
When accelerating using the N e-shift mode and letting off the accelerator the car continues to accelerate.
