The National Highway Traffic Safety Administration has upgraded its probe into roughly 1.7 million General Motors vehicles that may have been equipped with faulty windshield wipers.
We first reported on this matter back in November of 2018, when the NHTSA was deliberating whether or not to have all vehicles fitted with the potentially faulty wipers recalled. Prior to that in 2016, GM recalled roughly 367,808 Chevrolet Equinox and GMC Terrain vehicles from the 2013 model year for the same problem, but kept receiving complaints from owners of newer vehicles and believed that not enough vehicles may have been included in the original recall.
The new NHTSA engineering analysis probe includes Chevrolet Equinox and GMC Terrain vehicles from the 2010-2012 and 2014-2016 model years. If the NHTSA demands a recall following the probe’s completion, GM could will be forced to repair the wipers and wiper assembly ball joints in over 1.7 million vehicles.
The NHTSA claims it has received 1,900 reports related to the wiper issue. In affected vehicles, water and debris may work its way into the windshield wiper assembly ball joints, which can wear them down and lead to the eventual detachment of the wiper ball joint from the vehicle. In the recall of the 2013 model year vehicles, GM installed an improved windshield wiper motor and transmission assembly and relocated a drain hole at the base of the windshield to allow trapped water to escape.
In a statement sent to Reuters, GM said it will “fully cooperate to support their investigation,” and that it does not
“believe these windshield washer systems are defective.”
It is not clear when the NHTSA’s probe into the defective wipers will be complete.
