What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The brakes automatically engage without cause. The problem occurs at both city and highway speeds, from 20-75 mph. It is particularly bad when passing underneath a bridge. The car will abruptly stop. This has been ongoing for monthes.
I could see some items on-screen still, like the button to switch camera views and to toggle the parking sensors on/off. When switching camera views/angles, the system would continue displaying the same two black/empty displays.
Vehicle aggressively and without cause engaged the Automatic Emergency Braking System causing the driver to be slammed against her seat belt and almost having the car in back of us to almost rear end our vehicle.
The contact had experienced a failure where the vehicle would not start as needed. The contact related the failure to the recall. Parts distribution disconnect. The failure mileage was not available.
The cruise control is very abrupted when engaging the resume feature. The cruise will cause the transmission to downshift and engine to rev above 5000 rpms for just a couple of mph speed increase. I believe this a design flaw that could cause a driver to lose control of the car.
