Fiat Chrysler recalling 4.8 million vehicles, says do not use cruise control

Fiat Chrysler is warning drivers of 4.8 million of its vehicles to not use their cruise control feature until they get a software update under recall because they may not be able to turn it off.

The automaker has discovered that in certain situations a short circuit can make it impossible to cancel the system while the vehicle is moving. However, it said that the sequence of events that would lead situation is unlikely to occur. If it does, a heavy application of the brakes should be enough to stop the vehicle, with or without shifting into neutral, which will also mitigate the problem.
