NHTSA Complaint #11708551 — 2018 TOYOTA C-HR

My front camera sensor light came on stating it was unavailable, then turned back on after a few minutes. About a week later on several occasions, the emergency brake notification came on when I was on the freeway with no vehicles in front of me to cause this. There has been an excessive whirring sound coming from the engine also. With these issues there have been no warning signs including check engine lights or other vehicle maintenance lights on. Reading complaints from other Toyota, CHR owners with similar issues, and stating they’ve had costly transmission failure brings a great deal of concern for my safety and those on the road.
