Brakes on 2014 Chevrolet Impala Under Government Scrutiny

The National Highway Traffic Safety Administration (NHTSA) will open a preliminary investigation into the 2014 Chevrolet Impala.

According to the government agency, the probe focuses on an autonomous braking system, an increasingly popular safety feature among manufacturers. It activates the brakes without driver input if, in certain situations, the vehicle is in danger of hitting another vehicle or an object. The issue has been reported by a driver who said his car’s system has activated multiple times.

“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.” - NHTSA report

According to the NHTSA the driver experienced the situation on more than one occasion. In one instance his Impala was cruising at around 40 mph (65 km/h) when the system activated, causing the vehicle to stop and then struck by the car behind it. Fortunately, no injuries occurred in the accident.

The NHTSA is now assessing the problem to see if other vehicles were affected.

In the US, Chevrolet built around 60,000 Impalas in 2014.
