The National Highway Traffic Safety Administration (NHTSA) is launching an investigation into Ford following its failure to remedy problems from an earlier recall, CBT News reports.
Ford previously issued a recall that applied to certain 2020 through 2022 model-year Explorers with 2.3-liter engines, three-liter and 3.3-liter hybrids, Explorer Police hybrids, and 2020-2021 Explorers with 3.3-liter gas engines.
This recall was remedied by a software update from the automaker that would initiate an electronic parking braking in the case of a failing drive shaft. However, since the update was released, two vehicle owners have reported problems related to it.
One driver had their Explorer come to a halt at a speed of 30-40 mph before beginning to roll downhill, potentially as a result of disengaging the powertrain. Another driver experienced the vehicle suddenly moving while attempting to turn off the electronic brake.
According to a Ford official, the automaker plans to fully cooperate with the NHTSA’s investigation of the recall.
