The trucks covered include several variations of Ram 1500, 2500, 3500, 4500 and 5500 pickups from the 2010 to 2017 model years. All 2017 Ram trucks built after Dec. 31, 2016, are excluded from the recall.
The action covers 1.48 million trucks sold in the United States. Fiat Chrysler is also recalling 290,000 trucks sold in Canada and Mexico, and a small number sold in other markets.
Responding quickly to possible defects has become a closely watched matter for Fiat Chrysler. Two years ago, the National Highway Traffic Safety Administration found that the company had failed to promptly notify vehicle owners of recalls and delayed initiating repairs of defective models in 23 recalls covering 11 million vehicles. The agency fined Fiat Chrysler $105 million.
In 2016, the actor Anton Yelchin was killed when his Jeep Grand Cherokee, made by Fiat Chrysler, rolled backward down his driveway and crushed him. The vehicle had been part of a recall related to its electronic gearshift, but had not been repaired when the accident occurred.
This Ram recall involves a different type of shifter than the one in the Grand Cherokee. The shifter in the latest recall is mounted on the truck’s steering column. Ram trucks with floor-mounted gearshifts are unaffected by the recall.
