My jeep diesel had the software update for the crankshaft sensor tone ring, but the tone ring failed, and my car is stuck in limp mode. Is the replacement of the tone ring covered under the original recall,or do I have to pay for the repair?

- What is wrong
- Chrysler (FCA US, LLC) is recalling certain 2014-2019 Ram 1500 and 2014-2020 Jeep Grand Cherokee vehicles equipped with 3.0L Diesel engines.

- Risk
- An engine stall can increase the risk of a crash.
- Remedy
- Dealers will update the powertrain control module software to maintain vehicle propulsion, free of charge. Interim notification letters, notifying owners of the safety risk, were mailed August 3, 2023. Some owner notification letters were mailed October 31, 2023.

What 2015 Jeep Grand Cherokee owners say
Most recent owner complaints, unedited.
The contact owned a 2015 Jeep Grand Cherokee. The contact stated that while her son was driving approximately 40-45 MPH, the electronic control warning light illuminated before the failure. The contact pulled over and turned off the vehicle; however, the vehicle independently restarted. The contact exited the vehicle shortly afterwards, and the vehicle suddenly caught on fire. The fire department extinguished the fire. The contact associated the failure with the federal safety agency Complaint Number: 20V699000 (Engine and Engine Cooling). The vehicle was towed to a tow lot. The manufacturer was contacted by email and phone and opened a claim. The claim was declined. The investigator had taken photos. The contact was informed that the mileage had been exceeded. The failure mileage was approximately 150,000.
The tire pressure monitor system, the egr cooler. I had to change the egr the thermostat twice the engine the radiator the water pump and two oxygen sensors. The egr cooler is not recalled for my year but my truck was doin the same thing. The car still has a burning oil smell when the heat is on and the air don’t work
Recall 20V‑475 / 23V‑411 software patch was performed, but the underlying magnetic tone wheel defect has now physically failed, causing an active crankshaft position sensor error and stall hazard. While traveling 60mph the car stalled and went into limp mode with no prior warning. The vehicle has been diagnosed at a repair shop as a fault with the crankshaft position sensor performance which was apart of a pervious recall listed above. The vehicle has not been inspected by any others at this time as its not safe to drive and do not want out of pocket cost to do so.
I own a 2015 Jeep Grand Cherokee Summit 4x4 with the 3.0L EcoDiesel, with approximately 113,170 miles. The vehicle has experienced multiple intermittent episodes of “Service Electronic Throttle Control.” During the most recent episode, the vehicle briefly jerked/lurched forward and then experienced a significant loss of engine power/boost. I scanned the vehicle and found DTC P0336 (Crankshaft Position Sensor A Performance, intermittent). Clearing the code temporarily restored normal operation, but the fault later returned. During the most recent recurrence, the engine also cranked noticeably longer than normal before starting. FCA previously issued safety recall W79 concerning loss of crankshaft-position signal on these vehicles. The recall involved a software update intended to maintain engine operation using the camshaft signal if the crankshaft signal is lost. FCA also lists warranty extension X95 concerning the 3.0L diesel crankshaft tone wheel. FCA technical documentation identifies P0336 as a possible symptom associated with crankshaft tone-wheel magnetic material failure. The vehicle has not yet been inspected by a dealer or independent shop to confirm the physical cause. I have stopped driving it because I am concerned that an intermittent crankshaft-position problem could result in unexpected loss of motive power, engine stalling, or inability to restart. I contacted FCA Customer Care regarding this issue. FCA has indicated that the applicable warranty extension has expired and has not agreed to assist with the repair. I am currently using a rental vehicle while the Jeep is out of service. I am requesting that the federal safety agency document and review this suspected safety issue. The physical tone wheel has not yet been confirmed as failed, but the symptoms and P0336 code appear consistent with the failure mode described in FCA’s documentation.
My car started jumping after purchssing it in November 2025 used. The gear would feel like it was slipping. In March 2026 I parked my car turned it off let off the brake and it rolled. I have used the emergency brake since then. The gas gauge is off. The miles and gauge do not line up correctly and I was advised fuel pump may be off. It will drink gas up within a few miles. Check engine light came on without warning. Took it to check it out said oil sensor. He said replace it soon as you can still driveable. The next day i drove to my sons college and the jeep had no power, the check service on the screen popped up. And the jeep would not accelerate. I was anle to take it to O'Reilly and several codes appeared stating 2 gear shift ratio inaccurate 7 gear shift ratio inaccurate, engine oil pressure control circuit performance stuck off, clutch temp threshold achieved auto stick inhibit. The employee said he had never seen these codes populate. He asked if i had smelled any transmission fluid burning. I said no. No leaks nothing. Had the car for 7 months. He stated transmission isnt any good. That I would need a deep decoding done to say for sure. Car is in limp mode now. Unable to drive safely.
System Failed: Total engine failure caused by a defective Recall W79 EGR Cooler, which is available for physical inspection at my residence.Safety Risk: The vehicle suffered a sudden, complete loss of motive power at speed. This caused an immediate traffic hazard, risking a catastrophic rear-end collision due to lost propulsion, power steering, and braking.Dealer Verification: The vehicle is currently undrivable. Jeep Corporate is actively giving me the runaround and refusing to tow or diagnose the vehicle under the EcoDiesel Settlement Extended Warranty.Inspections: No inspections have been conducted yet by police, insurance, or the manufacturer; the vehicle is fully preserved.Symptoms/Warning: No long-term warning lights appeared. The vehicle suddenly lost AC cooling and instantly stalled out without advanced mechanical warning.
No check engine lights prior to this, car started to make a noise pulled over to check it out as I was merging over low oil pressure showed and coolant level over temperature, gear then dropped to neutral, managed to pull over without any accidents car then shut off, oil leaked, it makes a horrible engine noise when starting, had to tow it back. only had the car a year maintenance was up to date.
vehicle had a strong odor of gasoline then started spuddering and then caught fire while driving.
Sudden unintended acceleration while braking. Engine revved against brake input. Has happened multiple times. Need to step on the brake hard and wait for it to pass.
