Owner report 11618908 · 2024-10-09 (October 9, 2024)
On two occasions in the last month, when attempting to start the car, it doesn’t start, the interior dash lights start flickering, and a notification displays stating, “Parking brake cannot be applied”. I then have to “jump” the 12-volt battery. The main issue is the notification stating the parking brake cannot be applied because before shutting off the car the night before, I make sure the parking brake IS applied. However, it seems like the 12-volt battery is dead when I attempt to start it the following day; it automatically turns off the p…

Owner report 11663632 · 2025-05-29 (May 29, 2025)
Steering system, potentially related to electric power steering (EPS) or driver-assist systems (lane keeping or steering assist). While completing a routine right-hand turn, my husband began to straighten the steering wheel when the steering system suddenly and sharply turned further right without any driver input. This caused the vehicle to strike a curb, damaging both passenger-side wheels and the front tire. There were no warning lights or indicators, and road and weather conditions were normal. The uncommanded steering input appeared to c…
