The National Highway Traffic Safety Administration has launched an investigation into the 2014 Chevrolet Impala’s emergency braking system. This came after a consumer complaint that the car’s computer repeatedly slammed on the brakes for no reason. NHTSA opened the investigation on April 15, three weeks after receiving the complaint from a consumer who allegedly got into a fender-bender after his rented Impala’s braking system went awry. The Agency said on its website:
The consumer alleges that the driver assist system inappropriately activated emergency braking bringing the vehicle to a complete stop under what the driver considered to be full braking force.
According to the complaint, the rented Impala’s brakes first engaged automatically when the Impala was traveling at 20 mph, after which the car appeared to function normally. Then, the next day, the brakes seized up again at 40 mph, causing a minor accident with no injuries, the consumer alleged.
The second incident followed a series of warning beeps from the Impala’s “forward collision avoidance system,” even though there was no traffic directly in front of the car, which had only 2,500 miles on it, according to the complaint. The 2014 Impala – made by General Motors Co. – is a relatively popular model in the U.S., with 60,580 vehicles on the road.
