What Happened
The crankshaft position sensor in your vehicle is a critical sensor that helps the engine fire the fuel injectors at the right time. In some 2014-2020 Ram and Jeep models with 3.0L Diesel engines, this sensor's tone wheel can break apart, causing the engine to lose its timing and stall.
Risk if Unfixed
If the engine stalls, you could lose power while driving, which could increase your risk of being involved in a crash.
Free Fix
Your dealer will update your vehicle's computer system for free, to prevent the engine from stalling. This update will keep your vehicle running smoothly and safely. You should schedule this update as soon as you get the recall notice.
