Fiat Chrysler is recalling 229,000 Ram pickups due to a problem with the the trucks unexpectedly shifting out of park.

Fiat Chrysler will recall 229,000 Ram pickups due to a defect that cause them to unexpectedly roll away.

Because a pin can become dislodged inadvertently if a driver keeps a foot on the brake when it is shifted into park, the normal shift interlock mechanism can be deactivated, allowing the vehicle to unexpectedly shift out of park without a key in the ignition or a foot on the brake.

It is the latest in a series of transmission problems for the Detroit automaker, though most of the recent issues have involved new electronic shifters that don’t have a direct mechanical linkage to the gearbox. One issue was linked to the death of Star Trek actor Anton Yelchin, who was crushed by his Jeep two years ago.

The latest FCA recall covers Ram a variety of different versions of the Ram 1500, 2500 and 3500 pickups, as well as heavy-duty 3500, 4500 and 5500 Chassis Cab models. All 229,000 of the vehicles are equipped with shifters mounted on the steering column.

So far, FCA said, it knows of no crashes or injuries related to the defect. It is advising drivers to make sure to use the parking brake to prevent rollaways until repairs can be made.

Official notice will go out to owners in the coming weeks and repairs will be available after March 30.

This is actually the second recall linked to the problem. FCA previously targeted 1.8 million other Ram trucks in a service action launched in December.

That same month, federal officials said they were expanding a probe involving potentially defective transmissions in Ford F-150 pickups. The automaker previously recalled 153,000 of the trucks because they could unexpectedly shift into first gear while driving, leading to a loss of control. As many as 1.4 million F-150s, and Lincoln Navigator and Ford Expedition SUVs could be impacted.

The number of transmission recalls has been growing in recent years, according to government data, though a significant number of the problems involve the use of new e-shifters that are not directly linked to the transmission itself. That approach has become common with the introduction of new, high-efficiency eight-, nine- and 10-speed automatic gearboxes.

FCA was targeted in a federal safety investigation that was spurred by the death of Yelchin earlier that year, as well as other incidents linked to at least nine other incidents. With the e-shifters used in some Jeeps and other FCA products, however, the problem was blamed on an unusual shift pattern that were thought to confuse motorists who might shift into the wrong gear or fail to put the transmission into Park when shutting the vehicle down.

FCA ultimately recalled 1.1 million vehicles due to the bad interface design.
