2014 Jeep Grand Cherokee: check engine light

Filed Nov 2, 2026 · Brakes, Transmission · CT

My 2014 Jeep Grand Cherokee began popping out of gear (aka shifting into neutral suddenly) while at cruising speed several months ago. This causes the car to lose drive altogether at highway speed and requires the driver to pull to the side of the road in order to restart and resolve the issue. Before the restart, the power brakes fail to work any long and the driver needs to press very hard on the pedal in order to keep the vehicle stopped or slowed. This has no put myself and the drivers behind me at significant risk if the driver (my daughter) or me are unable to pull to the side of the road safely or if the cars behind us cannot avoid us. My mechanic cannot diagnose the issue. We changed the transmission and the problem has persisted. There are no warning lights or check engine lights associated with the error. It seems very similar to what's happening here -> [XXX] However, the Jeep dealership wants way too much money to diagnose the issue. I've seen the issue reported by other 2014 Grand Cherokee owners in forums with no resolution. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While maneuvering in a parking garage and switching between reverse and forward, the engine suddenly and unprompted revved excessively, sounding as though the accelerator pedal was floored. The vehicle forcefully lunged forward against braking pressure into a cement wall, causing front-end damage to the vehicle. Cruise control was completely disabled and no check engine light or warning indicators illuminated on the dashboard. At no time did I feel like I had control over the car. I sustained some contusions. No one was in the vicinity at the time; however, other cars and/or people could have been struck. The vehicle has yet to be examined by anyone although I am in the process of arranging for an autobody repair shop. Prior to this, the car was in its usual state of health without any issues.

My Son just bought the car from a private party. On our way home the engine light and a lightning bolt icon illuminated on the dash, followed by the vehicle going into limp mode. We had the vehicle scanned for codes and it came back with P0336 (crankshaft position sensor performance). After much investigation online, we found out that this is a known issue with the crankshaft position sensor and, most importantly, the tone wheel on the back of the engine. We looked up recalls on the vehicle and found a safety recall had been issued. While some vehicles affected received replacement of the tone wheel and sensor, others just received a software update. This particular vehicle received the software update. The issue is that the magnetic material on the tone wheel delaminates from the tone wheel. This is a costly repair that should have been fixed correctly from the beginning, not just a software patch. It is a safety concern because it is dangerous when you are traveling at highway speeds and it goes into limp mode.

The monostable shifter malfunctions constantly. Safety-related concerns include it not staying in park when parked, rolling has occurred; not being able to start due to it not actually being in park; it will switch gear while driving and vehicle will go into limp mode and shut off within seconds, then will not be able to restart. I cannot count on it starting or getting me anywhere safely and have towed multiple times now. The problem has unfortunately not been reproduced or realized by local dealership even with ‘service shifter’, ‘until you reach a desired location you may not be able to shift again NO BUS’, and engine light warning lights appearing when driven. It has been taken twice to John Hiester Chrysler Dodge Jeep Ram of Sanford. (NC). I have spoken with Jeep Customer Care to no avail and the answer is take to a certified dealership but that option is proving to not be successful. I purchased in February 2025 but became disabled right after and haven’t realized it’s very major issues. Not being able to use my vehicle is quite isolating [XXX].

Engine light came on: took in for service. The dealer recommends replacing a damaged Intake Manifold for $2,247. 33. It appears there are recalls on these for same year as my vehicle involving both Jeep and Ram Trucks. However My vin does not fall into the recall? I find this odd and I understand there has to be a cut off, but i believe my vehicle was made around the same time and I don’t think Chrysler was aware of the problem until later… I also have Engine Oil cooler leaking which I am unsure if it is related, but now I have extensive repairs for Coolant flushing/ radiator hoses and coolant hoses, metal fuel lines, and thermostat… I am just disappointed that a recall is valid on the same model and year as mine, I was unaware and now I have a $8,570.40 quote to get this fixed. I am wondering if the EGR cooler failure has led to this massive problem as I am aware the engine oil cooler and EGR cooler are releated along with manifold function/ efficiency. Now I have Oil and coolant mixing in my system… If my eco diesel jeep were included in the original recall, I may not be dealing with this unexpected visit.

My TCM (Transmission Control Module). Yes. While driving my jeep kept shifting into Nuetral all by itself and I would have to shift back into Drive. This is going into my jeep dealer on 8-5 and put on the diagnostic test. It was only checked out by plugging in the meter and this is the code that came back. Has not been inspected by police, insurance, Jeep dealer as of yet until 8-5-25. Yes it went from shifting g into Nuetral by itself to Slow g down on its own and it happened most recently on a major interstate with an 18 wheeler behind me and almost rear ended me. As I gave it gas it wouldn’t go I rolled to side of road. This was the 5th time this happened to me. It all started back in beginning of July. The check engine light came on.

The engine and powertrain are affected by a defect described in Safety Recall 66A / the federal safety agency 23V‑411 (loss of crankshaft position). Despite the recall software update being performed, my 2014 Jeep Grand Cherokee continues to display Diagnostic Trouble Code P0336 (Crankshaft Position Sensor Performance). This issue causes intermittent stalling, hard starts, and loss of engine power, which creates a serious risk of crash if the vehicle stalls while driving. The safety defect described in the recall — tone wheel magnetic material delamination leading to crankshaft signal loss — is still present. Two diagnostic reports (one from an FCA-authorized dealership and one from an independent mechanic) confirm the presence of DTC P0336. The Service Manager at the dealership agreed this is likely recall-related but said FCA corporate must authorize hardware repair. FCA (Case #93427994) has refused to approve full repair, leaving the safety defect unresolved. The defect has been confirmed by the dealership and independent service center and persists despite the software reprogramming remedy. Warning lights (check engine) are active and the issue is repeatable.
