The crankshaft position sensor is a small part that tells your engine when to fire the fuel injectors and sync the engine's timing. In some 2014-2020 Ram 1500 and Jeep Grand Cherokee models with 3.0L Diesel engines, this sensor's coating can wear off, causing the engine to lose synchronization.
Risk if Unfixed
If this happens, your engine could stall while you're driving, which increases the risk of a crash. This could happen suddenly and without warning, making it harder to control your vehicle.
Free Fix
Your dealer will update the computer system that controls your engine, at no cost to you. This will ensure your engine runs smoothly and safely. The repair is free, and you should schedule it when you receive the recall notice.
