When does it fail?
Of the 19 engine complaints filed for the 2020 Jeep Cherokee, here's the actual mileage breakdown — failures cluster heaviest at 0-25,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
No new NHTSA engine complaint has been filed on this vehicle in over 3 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Before replacing any parts please refer to SOL S2518000008 if it applies to the vehicle you are working on based on a VIN search in Service Library. Before replacing this part due to Engine Light On with P1CEA (Boost Side EVAP Purge System Performance), check for: 1) Improperly connected or kinked/pinched Purge Hoses at the Ejector Tees on the Air Box or Duct. 2) Improperly connected or kinked/pinched Purge Hose at the Purge Solenoid or OBD Valve. 3) Improperly connected or kinked/pinched Purge Hose at the Intake. 4) Check for the correct Purge Hoses installation.

The failure pattern owners describe
The 2020 Jeep Cherokee engine complaints fall into several distinct categories. Early-life power loss and stalling appear within the first 500 miles to 2,000 miles, with check-engine lights and throttle-issue messages, sometimes clearing after sitting four hours. Overheating and fire are the most severe: multiple owners reported vehicle fires between 3,000 and 26,900 miles, some while driving at highway speeds, others while parked. These fires occurred suddenly with burning odors, flames from the engine compartment or front end, multiple explosions, and complete vehicle destruction. Several owners reported the four-wheel-drive system overheating warning light preceding fires.
Oil-related failures appear frequently. Low oil pressure warnings appear as early as 1,400 miles, with one dealer acknowledging the issue but recommending owners add a quart every 1,500 miles. Oil consumption of up to 3 quarts by 26,000 miles has been reported. Oil leaks from the canister and oil-filter housing (plastic) have been noted, with concerns raised about fire risk. One owner reported a piston failure and complete engine failure. Active grill shutter malfunction has caused check-engine lights and temperature-gauge issues, with replacement costs cited around $600. Oxygen sensor and PCM failures requiring multiple repairs within 2,000 miles have also been documented. One owner reported jerking and abnormal sounds at 49,413 miles with no warning light.
