Fiat Chrysler Automobiles is recalling approximately 4.8 million vehicles in the United States as the company has determined an “unlikely sequence of events” could prevent the cruise control system from being deactivated.

According to the automaker, someone has to be driving one of the affected models with the cruise control system activated. The system would then need to increase the speed of the vehicle at the same time there’s a short-circuit in a “specific electrical network.” If this occurs, the driver may discover they cannot cancel the cruise control system.

While this would be pretty scary, FCA says drivers can overpower cruise control acceleration by using the vehicle’s brakes. The company also notes drivers can shift the car into neutral and then brake accordingly. Regardless of which option is used, cruise control will be cancelled once the car is put in park.

In a statement, FCA’s Chief Technical Compliance Officer and Head of Vehicle Safety & Regulatory Compliance for the NAFTA region said “Notwithstanding the extraordinary circumstances that must exist before a customer would experience a problem, we are taking this action because we are fully committed to vehicle safety.” Mark Chernoby went on to say “We have a remedy and a widespread network of engaged dealers who are preparing to deliver service.”

FCA will be notifying customers next week and the company recommends that owners don’t use the cruise control system until their vehicle has been equipped with updated software to correct the problem. That being said, the company is unaware of any injuries or accidents related to recall even though affected models have clocked over 200 billion miles (321 billion km).

2015-17 Chrysler 200 sedan
