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
Few of these reports name the part that was replaced.
Recalls and investigations
3 recalls on the engine cover the 2019 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.

Is this a known problem?
The manufacturer has sent NHTSA 20 service bulletins or notices for the 2019 Jeep Grand Cherokee that deal with this problem. Newest first.

Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

Should you keep driving it?
This page can't tell you that. 0 of 32 reports involved a crash. 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.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
