Typical collision avoidance system symptoms owners report
- Owners report the Smart Brake System (SBS) suddenly and forcefully applying the brakes at highway and city speeds with no obstacle present.
- Some describe a collision warning alert or 'Brake!' message on the dash followed by an automatic full stop, even in stop-and-go or slow traffic under 5 mph.
- Several drivers say the vehicle braked hard for cars in adjacent lanes or for vehicles far ahead with plenty of stopping distance.
- One owner reported the front radar sensor failing outright, disabling forward collision warning and adaptive cruise control, reportedly linked to water intrusion.
