The crankshaft position sensor tone wheel in your vehicle is a small metal ring that helps the engine know when to fire the fuel injectors. In certain 3.0L Diesel engines, this ring can break apart, causing the engine to lose its timing and stall.
Risk if Unfixed
If the engine stalls, you could lose control of your vehicle, especially if you're driving on the highway or in heavy traffic. This increases the risk of a crash.
Free Fix
Your dealer will update the computer system that controls your engine, ensuring it keeps running smoothly. This update is free, and you should schedule it as soon as you get the recall notice.
