2013 Jeep Grand Cherokee engine problems

Filed Aug 18, 2026 · Engine, Transmission · GA

My 2013 Jeep Grand Cherokee equipped with the 3.6L Pentastar v6 has a persistent cylinder 2 misfire (P0302). The cylinder 2 spark plug, ignition coil, and fuel injector have already been replaced, but the misfire continues. Diagnostic testing with a scan tool confirmed that cylinder 2 accumulated 61 misfires during a single test while cylinders 1,3, 4, 5, and 6 recorded zero, and the misfire monitor reported " Fail this trip" the vehicle can appear to drive normally despite the active misfire. I became aware that Chrysler issued warranty bulletin x56 concerning the 3.6L left cylinder head on certain 2011- 2013 vehicles including select 2013 Jeep grand Cherokees. I contact a jeep dealer and advise that my VIN is not included in that warranty extension. I am reporting this because my vehicle is experiencing a similar cylinder specific misfire concerns and I believe this condition should be documented and investigated.

I will be going 50-65 mph down the highway and my jeep will just die. It will die for about 10-15 seconds then start again. This is very dangerous. I have talked to multiple people that this has happened too.

- The core component that failed is the Totally Integrated Power Module (TIPM). The failure was initiated by a fault in the external fuel pump relay (V62 Safety Recall remedy part), which caused improper power delivery. This improper power delivery subsequently damaged the fuel pump motor, requiring replacement of both components. This failure has cascaded, also disabling the circuits for the Engine Cooling Fan (Codes P0480/P0693) and Exterior Lighting (Headlights/B1630), and the Horn. I am in possession of the burnt-out fuel pump relay/fuse component. -The engine stalled while the vehicle was operating, the exact hazard the V62 recall was meant to prevent. This was followed by a catastrophic TIPM breakdown, creating new, simultaneous safety risks: Overheating/Fire Risk: The Cooling Fan circuit failed (P0480/P0693), causing severe engine overheating. No Headlights: The Headlights failed (B1630), causing total loss of visibility at night. No Horn: The Horn failed, eliminating the ability to warn other drivers. - Yes. The initial engine stall and subsequent no-start condition (due to a blown relay fuse) were confirmed by an independent service center (Monro). The cascading failures (overheating, horn, lights) and the diagnostic codes (P0480, P0693, B1630, C2201-00) were confirmed on 11/1. - The vehicle was inspected by an independent service center (Monro), who returned the failed recall component to me (relay). Recommend it go to a certified jeep dealership. It is waiting to be towed there. -The first warning was a history of intermittent starting difficulty. On 10/23, the engine stalled while operating and immediately resulted in a no-start condition. The Check Engine Light illuminated after the subsequent failed restart attempts.

Vehicle has stalled over twenty times, whether driving on the highway over 60 mph or driving locally within 20 MPH. Initially stalled December 25, 2022 while driving home on Christmas Day with my entire family, driving full speed on the highway. I felt the stall and pulled over as quickly as I could. Attempted to restart several times and engine would crank but not start until after 5-7 attempts and several minutes. Since then I continue to experience the same stalling and attempts to restart vehicle. Took to service center multiple times and they are unable to determine the issue. Fuel pump relay was changed twice by the dealership. I had to pay $1500 one time as they said the cost was not covered, which is ridiculous since the problem reoccurred many times after that. Most recently, fast forward to almost 1.5 years later and the issue is still occurring. Now it stalled and appears to be rolling back when in drive until I shift the gear to park and move the gear several times. It has been losing traction and power. I really need someone to determine a resolution to the issue as this is a severe safety issue and I am very concerned about driving it.
