DETROIT, Michigan -- Fiat Chrysler is recalling 4.8 million vehicles in the U.S. because in rare but terrifying circumstances, drivers may not be able to turn off the cruise control.
The company is warning owners not to use cruise control until the cars, SUVs and trucks can be fixed with a software update.
Fiat Chrysler says the condition can occur if the cruise control accelerates at the same time an electrical short-circuit happens. But the brakes are designed to overpower the engine and the vehicles could still be stopped. Shifting into park would cancel the cruise, but tapping the brakes or turning off the cruise control button won't work.
The problem was found in testing of the vehicles' computer network. FCA says it has no reports of crashes or injuries. After the testing uncovered the trouble, FCA said it reviewed customer complaints and found only one that may be related.
The recall includes 15 Jeep, Dodge, Chrysler and Ram models from six model years with gasoline engines and automatic transmissions.
Models in Canada, Mexico and other countries also are affected, but the company is still sorting out which ones.
Affected models include the 2014-2019 Ram 1500 pickup, as well as the 2014-2018 Ram 2500, 3500, 4500 and 5500 pickups and chassis cab trucks. Also covered are the 2015-2017 Chrysler 200, the 2014-2018 Chrysler 300, the 2017 and 2018 Chrysler Pacifica minivan. Dodge vehicles included are the 2015 to 2018 Challenger, and the 2014 to 2018 Charger, Journey and Durango, while affected Jeeps include the 2014 through 2018 Cherokee and Grand Cherokee and the 2018 Wrangler.
Fiat Chrysler will begin notifying customers as early as next week. The company is urging customers to follow the recall instructions and get the repairs done as soon as possible.
