Misfire on other Grand Cherokee years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2016, 2020, 2021, 2022, 2023, 2024, 2025, 2026.
What this problem usually is
These reports start with the check engine light. Many describe the engine running rough or shaking at idle, a P0300-series code, or a catalytic converter code. A worrying number say the light was flashing. Owners often list ignition coils or spark plugs already replaced, and the light coming back afterward.
What got replaced
Owners who name the part that was replaced mention the sensor (9 reports), the ignition coils (5 reports), the injectors (5 reports) and the catalytic converter (4 reports).
Recalls and investigations
11 recalls on the engine cover the 2014 model year. A recall on the same system isn't always the same failure, so read the defect text.
The crankshaft position sensor tone wheel may delaminate, causing the engine to lose its ability to synchronize the fuel injector pulses and cam shaft timing, possibly resulting in an engine stall.
A high pressure fuel pump (HPFP) failure may introduce internal debris into the fuel system, potentially resulting in fuel starvation.
The Exhaust Gas Recirculation (EGR) cooler may crack and allow pre-heated vaporized coolant to enter the EGR system. This mixture may combust inside the intake manifold.
The crankshaft position sensor tone wheel may delaminate causing the engine to lose its ability to synchronize the fuel injector pulses and cam shaft timing, possibly resulting in an engine stall.
These vehicles are being recalled to address a defect that could prevent the cruise control system from disengaging.
In the affected vehicles, the alternator may suddenly fail.
The supercharger mounting bracket may contact and damage the ABS line, possibly resulting in a brake fluid leak.
The affected vehicles have electro-hydraulic power steering (EHPS) and are equipped with a 5.7L or a 3.6L engine and a 160, 180 or 220 amp alternator. In the affected vehicles, the alternator may suddenly fail.

In the affected vehicles, the alternator may suddenly fail.

Should you keep driving it?
This page can't tell you that. 2 of 95 reports involved a crash and 1 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
