BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

Kia America, Inc. (Kia) is recalling certain 2020-2022 Niro EV vehicles. The circuit board for the rearview camera may become damaged and cause the rearview camera image not to display. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numb

The rear brake rotors on the vehicle are pitted, as confirmed by a local repair shop. The "incident" is ongoing. Kia refuses to repair or replace them under warranty (25,500 miles on the car), claiming they are wear item. However, pitting is not wear, in fact quite the opposite. My analysis (30+ yrs in the auto business): As an EV, regenerative braking means the actual brake systems are rarely used. Noise at low speeds prompted the inspection at a local shop. Braking under high speeds does not result in noise, telling me the system relies too heavily on the front brakes. The result is the rear rotors are too often unused leaving them to rust and then pit. Tesla recognizes that regen braking can actually harm brake rotors, suggesting burnishing the brakes at times using the following procedure: 1) Drive the vehicle at approximately 50 mph - 55 mph (80 km/h - 90 km/h) on a straight road. 2) Apply moderate, consistent pressure to the brake pedal to slowly decelerate the vehicle, relea

20210730BACK OVER PREVENTION: BACK-UP ALARM

I'm a new Niro Ev driver. The VESS noise when reversing the vehicle is very loud. It is too loud, I live in close proximity to neighbors and have to get up early for work and the sound is a major nuisance, I would not want a neighbor that has this car . I understand VESS in place for safety but the reverse backup beeping is just a step down from a garbage truck backing up, especially in the silence of a residential neighborhood in the early AM hours. Furthermore, I and others as seen on web forums will reverse faster than we normally would do to be able to take the car out of reverse as quickly as possible to stop the blaring beeping. This creates its own risk, as if there is less time to react if there is a pedestrian behind the vehicle. The volume of the noise should be greatly reduced. It is also unnecessary noise pollution. Kia, please fix this.
