On several occasions since Iâve owned the vehicle, it has come to a complete stop while driving at highway speeds without any apparent reason, accompanied by a warning of a possible collision. On one such occasion, the vehicle stopped so abruptly that I initially thought I had been rear-ended, though thankfully no cars were near me at the time. If other vehicles had been nearby during any of these incidents, I believe it could have resulted in a serious accident. While I am grateful for the technology, as it has also helped me avoid an accident on two separate occasions (different from the above referenced instances), I believe the system needs improvement to prevent these unexpected stops from occurring.
