Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The car's overall electronic reliability and safety are huge areas of concern. Rearview camera and sensors do not always work. Sometimes it will operate while car is in motion but it will black out which ultimately impairs the driver's ability to reverse and avoid any objects and pedestrians. This is potentially dangerous in high-foot traffic area like shopping mall. In addition, the car's lane assistance mechanism is not accurate at times and could have caused accidents several times. …”
