Feds Close Probe Into 2014 Chevrolet Impala for Unintended Autonomous Braking


WASHINGTON — The National Highway Traffic Safety Administration has closed an investigation into 105,765 2014 Chevrolet Impala sedans for unintended autonomous braking, the agency announced on Tuesday.

The federal safety agency received two consumer complaints alleging incidents of "inappropriate autonomous braking while driving, resulting in unexpected sudden and rapid deceleration in traffic," it said.

During the probe, General Motors investigators inspected two crash-incident vehicles and examined the electric parking brake switches to assess potential mechanical and electrical fault conditions. The two were rental cars. The probe began last April.

The investigators told NHTSA they believe that the drivers in both cases accidentally activated the electric parking brake system.

"GM did not identify any faults in the subject components or systems that could have caused or contributed to autonomous brake applications," NHTSA said.

The investigation is closed and the cars are not being recalled for this concern.

"The closing of this investigation does not constitute a finding that a safety-related defect does not exist," NHTSA said.

Edmunds says: Consumers who have been following this investigation are reassured that the 2014 Chevrolet Impala is not being recalled for an active safety system malfunction.
