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.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:GAS RECIRCULATION VALVE (EGR VALVE)
Manufacturer
Chrysler (FCA US LLC)
What Happened
The EGR valve in your Jeep Grand Cherokee helps reduce pollution by circulating exhaust gases. In some 2014-2019 models with the 3.0L EcoDiesel engine, the cooler that helps this system work can crack and let coolant get into the EGR system.
Risk if Unfixed
If this happens, the coolant can mix with air and ignite inside your engine's intake manifold, which could cause a fire. This is a serious risk, especially since it could happen while you're driving.
Free Fix
Your Jeep dealer will replace the faulty EGR cooler and inspect your intake manifold, and fix it if necessary - all for free. You'll be notified when parts are available, and you should schedule the repair as soon as you can.
