Dodgy software code controlling side airbags and safety belt pretensioners is responsible for a recall affecting more than a million Ram pickup trucks. On Friday, Fiat Chrysler Automobiles (FCA) announced that it will be recalling Ram 1500 and 2500 trucks (model years 2013 to 2016) and Ram 3500 trucks (model years 2014 to 2016) beginning in June in order to rectify the problem.

The software error, which could prevent side airbag deployment and belt pretensioning in cases where a vehicle rolls over following an underbody impact—say, hitting road debris or something when off-roading—has already been implicated in one death. Although the code has not been conclusively fingered as the culprit, FCA says it is issuing the recall proactively.

A similar issue forced General Motors to recall more than 4 million vehicles in 2016.

FCA will be contacting owners of affected vehicles, but the National Highway Traffic Safety Administration also has a handy tool that lets you search by vehicle identification number.
