What Happened
The crankshaft position sensor in your vehicle is like a heartbeat monitor for your engine. It helps the engine know when to fire the fuel injectors and keep your engine running smoothly. In some 2014-2020 Ram 1500 and Jeep Grand Cherokee models with 3.0L Diesel engines, this sensor's tone wheel can break down, throwing off the engine's timing and causing it to stall.
Risk if Unfixed
If your engine stalls, you could lose control of your vehicle, especially if you're driving on the highway. This increases the risk of a crash, which could put you and your passengers in danger.
Free Fix
Your dealer will update the computer system that controls your engine, ensuring it keeps running smoothly. This update is completely free, and you should schedule it as soon as you receive your recall notice so you can drive safely.
