According to the NHTSA, the complainant reported being rear-ended after his rented Impala’s “driver assist system inappropriately activated emergency braking, bringing the vehicle to a complete stop.” The car was running 40 mph before the collision occurred.
The automatic braking system, which has become a common safety feature in today’s cars, automatically activates the brakes when the vehicle’s sensors detect a possible collision.
In his report, the driver said he heard three to four beeps from the forward collision avoidance system of the Impala before the brakes brought the car to a complete stop, causing it to be struck from behind. He also said that he experienced the glitch three or four times before.
General Motors have been notified about the incident and the complaint. It said it is now cooperating with the NHTSA’s initial investigation, which involves over 60,000 Impala units in the United States.
GM is now adding 35 safety investigators as it restructures its engineering operations in response to a massive safety recall of some 2.6 million Chevys and other models.
