Unintended Acceleration / Vehicle Speed Control

Complaints indicate the vehicle may continue to accelerate after the accelerator pedal is released, particularly when using the N e-shift mode. This is often linked to software issues within the Vehicle Control Unit (VCU). Estimated repair cost: $500 - $2,000+.

Electrical System Failures (12V Battery, ICCU)

Owners report 12V battery failures and ICCU (Integrated Charging Control Unit) replacements, with some instances of complete power system failure. These issues can lead to unexpected inoperability. Estimated repair cost: $300 - $1,500.

One reported failure of the ABS module at approximately 9,200 miles led to unintended acceleration and delayed braking response, presenting a critical safety defect. Estimated repair cost: $1,000 - $2,500.
