Federal safety regulators are investigating complaints that Ram 1500 pickup trucks and Dodge Durango sport-utility vehicles have rolled away after being parked.
The probe is looking at whether there is a defect that could potentially affect 1 million vehicles from the two brands, which are divisions of Fiat Chrysler Automobiles.
Investigators from the National Highway Traffic Safety Administration are looking at Ram 1500 pickups from the 2013 through 2016 model years and Dodge Durangos from the 2014 through 2016 model years.
The also said they are looking at a similar problem in Land Rover Evoque SUVs from the 2012 through 2014 model years and 2013 model year Jaguar XF cars.
The agency said it has received 43 complaints of Ram and Dodge vehicles rolling away after they were parked. Nine injuries and 25 crashes have been blamed on the problem, according to the NHTSA report.
NHTSA’s Office of Defects Investigation said the vehicles are equipped with an electronically shifted transmission and electronic rotary control for driver gear selections.
“The reports alleged that the unintended motion occurred after the driver moved the transmission gear selector to Park and exited the vehicle,” NHTSA said. “Thirty-four of the reports alleged that the vehicle was moving while the shifter indicated that it was in the park position.”
Safety regulators noted that none of the reports indicated that the parking brake on the vehicles was engaged at the time of the roll-away incident and warned drivers to always apply the parking brake to prevent vehicle roll-away.
FCA said in a statement that it is cooperating “fully with NHTSA's investigation.”
The automaker said the scope is limited and does not include its other vehicles equipped with rotary shifters are not included.
FCA said it “joins NHTSA in urging all drivers to use their vehicles' parking brakes.”
NHTSA said it has reports of 7 crashes and 4 injuries with the Jaguar and Land Rover vehicles. Those brands are owned by Jaguar Land Rover, a British car manufacturer and are not part of FCA.
