2 known faults with sources

Applies if: Third-generation engine (from 2020): mainly the fuel-pump campaign and oil-pressure warnings.

EGR cooler and bearings on the VM 3.0 V6 diesel (EcoDiesel)Engine

Engine / equipment: VM Motori 3.0 V6 diesel (A630, “EcoDiesel”): Jeep Grand Cherokee and Gladiator, Chrysler 300C, Lancia Thema and Maserati Ghibli, Quattroporte and Levante
Period mentioned: 2011 onwards
Symptoms: Coolant loss, white smoke or combustion in the intake manifold (cracked EGR cooler); deep metallic knock and the oil-pressure warning (bearings); on engines from 2020, low oil-pressure warnings or a failing high-pressure pump shedding metal.
Possible cause described: According to mechanics and owners, the EGR cooler cracks from thermal fatigue (Chrysler recalled it) and the crankshaft bearings can fail from lugging at low revs or carbon in the oil passages. On the third generation (from 2020) there was a recall for the Bosch CP4.2 fuel pump. Maserati uses the same VM engine in its diesels.
Check for the garage: Check the EGR-cooler and pump campaigns by VIN; watch the coolant and oil pressure; with knocking or the oil warning, stop. Avoid lugging the engine at very low revs under heavy load.

Diesel high-pressure pump, driveline and steering on the GladiatorKnown weak points

Engine / equipment: Jeep Gladiator JT (3.6 V6 and 3.0 V6 CRD)
Period mentioned: 2020 onwards
Symptoms: On the 3.0 diesel, the high-pressure fuel pump can fail and stall the engine (2021–2023); a rear driveshaft assembled without grease in the joint (2020); a gearbox park pawl that may not engage (2022); an instrument cluster that goes blank (2020–2024); power-steering pump wiring that can overheat and cause a fire even when parked (2021 onwards).
Possible cause described: Defects documented by US recalls (NHTSA 22V-767 and 23V-263 for the diesel pump, 19V-636, 22V-639, 24V-652 and 26V-363). European cars may have equivalent campaigns: check by VIN.
Check for the garage: Check campaigns by VIN; if the diesel stalls, check the high-pressure pump.
