What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
During the unintended acceleration, the vehicle traveled over multiple curbs on both sides. No audible warnings, no beeping, no proximity alerts, no forward-collision warnings, and no automatic emergency braking activated at any time, despite the vehicle crossing curbs and approaching fixed objects.
I was advised that there may be an issue involving the high-voltage battery that could lead to battery failure and/or an increased risk of fire. Due to this warning, I no longer feel the vehicle is safe to operate or park near my home or other structures.
Learning that my vehicle is subject to a battery-related recall has seriously undermined my trust. Battery defects in electric vehicles can present risks that include thermal events, loss of vehicle functionality, and other potentially dangerous situations.
