NHTSA upgrades probe into 1.7 million GM vehicles’ windshield wiper failures

The U.S. National Highway Traffic Safety Administration (NHTSA) said Tuesday it is upgrading an investigation into 1.7 million General Motors Co (GM.N) vehicles for windshield wiper failures.

The auto safety agency opened the probe in November 2018 to see if GM needed to expand a 2016 recall of 2013 model year Chevrolet Equinox and GMC Terrain SUVs to cover additional vehicles.

The engineering analysis probe covers 2010-2012 and 2014-2016 Equinox and Terrain vehicles. NHTSA could demand a recall after it completes the probe.
