On certain vehicles, a software error could cause false forward collision warnings (FCW) and/or activate the automatic emergency brake (AEB) system. If this happens, the vehicle could come to a sudden stop.
Safety Risk
A vehicle that brakes or stops suddenly when there is no risk of a collision could create an increased risk of a rear-end crash.
