What Happened
The crankshaft position sensor tone wheel is a small metal ring that helps your engine know when to inject fuel and when to turn the engine's valves. In some 2014-2020 Ram 1500 and Jeep Grand Cherokee models with 3.0L Diesel engines, this ring can break apart, causing big problems.
Risk if Unfixed
If the sensor tone wheel fails, your engine could stall without warning, losing power. This could make it hard to control your vehicle and increase the risk of a crash.
Free Fix
Your authorized Chrysler dealer will update the engine's computer software to prevent an engine stall, at no cost to you. This will ensure your vehicle stays running smoothly and safely.
