What's wrong, in plain English
Some 2021 Ram 1500 trucks with the 5.7-liter eTorque engine have a computer chip, called the powertrain control module, that controls the engine. A software problem in this chip can cause the engine to get the wrong mixture of fuel and air. This incorrect fuel mixture can cause the engine to stall while you are driving.
What you should do
Contact a dealer to schedule the free repair, or call FCA US customer service at 1-800-853-1403.
The software update will be installed at no cost to you.
Where do I find my VIN, and what do I tell the dealer?
