Water-cooled oil cooler's plastic check valve degrades, mixing oil and coolant · more· less
The VM Motori A630 uses a water-cooled oil cooler with an internal plastic check valve that deteriorates under sustained heat cycles. When it fails, engine oil leaks into the coolant system (visible as oil floating in the expansion tank) or coolant contaminates the oil. Early detection and replacement of the cooler costs €800-1,500, but if the contamination goes unnoticed, it leads to bearing damage and potential engine seizure (see next item). FCA's European bulletin 18-087-16 / RRT 16-073 changed the factory oil specification from 5W-30 to 5W-40 on specified 2016 cars built through 30 June 2016, so check the service book for which grade the car was filled with. Check for any discolouration or oil residue in the coolant header tank at every service.
Crankshaft and rod bearing failure
€5,000 - 12,0002 of 8
Bearings can spin in their journals, often as a consequence of undetected oil cooler failure · more· less
The most catastrophic failure on the VM Motori 3.0 V6 involves connecting rod and main bearings spinning in their journals, scoring the crankshaft. This is often a consequence of oil dilution from a failed oil cooler, though some cases trace to assembly quality inconsistencies. Symptoms include a deep metallic knocking from low in the engine and low oil pressure warnings. A bottom-end rebuild runs €5,000-8,000; complete engine replacement can reach €10,000-12,000. Use the oil grade specified for the individual car, checked against its build date and VIN, and inspect the cooling system at every service. Owners who catch oil cooler problems early and maintain the correct oil specification significantly reduce this risk.
EGR cooler cracking
€800 - 1,5003 of 8
Thermal fatigue cracks the EGR cooler, vaporized coolant can enter the intake manifold · more· less
A recall (NHTSA 20V-699, FCA designation W79) was issued for 2014-2019 Grand Cherokee 3.0 CRD models because the EGR cooler can crack from repeated thermal cycling. A cracked cooler bleeds vaporized coolant into the EGR system, potentially causing an intake manifold fire. Symptoms include unexplained coolant loss and soot/sludge buildup in the coolant expansion tank. The recall remedy is a replacement EGR cooler and, where necessary, a new intake manifold, free of charge. Verify with a Jeep dealer using the VIN whether this recall has been completed. If out of recall scope, replacement costs €800-1,500.
Quadra-Lift air suspension failure (if equipped)
€2,000 - 4,0004 of 8
Air springs leak, compressor fails, or valve body malfunctions on Overland/Summit trims · more· less
The Quadra-Lift air suspension is fitted to Overland, Summit, and higher-spec trims. The air springs develop leaks over time, especially after exposure to road debris and harsh conditions. The compressor, mounted under the vehicle behind the rear axle, is exposed to water and mud and commonly fails. When one air spring fails, the others on the same axle are usually close behind. A single air spring replacement costs €800-1,200; compressor replacement runs €1,200-1,800; a complete system overhaul can reach €3,500-4,000. Aftermarket replacements are significantly cheaper than Mopar parts. Some owners opt for a coil spring conversion kit (€600-800) to eliminate the air suspension entirely, at the cost of losing ride height adjustment.
ZF 8HP torque converter shudder (post-2013)
€1,500 - 3,5005 of 8
Torque converter clutch friction material degrades, causing vibration at light throttle · more· less
Post-2013 facelift models use the ZF 8HP70 8-speed automatic. The diesel's high torque output stresses the torque converter clutch more than petrol applications. The TCC lining material can glaze under heat, releasing debris into the valve body. Symptoms are a steady vibration between 40 and 70 km/h under light throttle. Well-maintained units with correct ZF Lifeguard 8 fluid changes every 80,000-100,000 km can reach 300,000+ km. Neglected gearboxes where the fluid was never changed can fail around 150,000 km. A valve body replacement costs €1,500-2,200; a torque converter replacement runs €2,500-3,500. Never use generic ATF in a ZF 8HP.
TIPM electrical failure (2011-2013)
€600 - 1,2006 of 8
Totally Integrated Power Module can cause fuel pump relay sticking and random electrical faults · more· less
The 2011-2013 WK2 uses a TIPM (Totally Integrated Power Module) that integrates solid-state relays and microprocessor control for all major electrical systems. The internal fuel pump relay can stick in the closed position, causing the fuel pump to run continuously even with the ignition off (draining the battery overnight), or fail entirely, preventing the engine from starting. Other symptoms include random electrical faults, erratic window operation, and horn activation. FCA issued recalls for certain affected models. A replacement TIPM unit costs €600-1,000 from aftermarket suppliers; TIPM repair/rebuild services exist for €300-500. This issue is far less common on 2014+ models.
DPF clogging and regeneration failure
€800 - 2,5007 of 8
Short-trip driving clogs the particulate filter, triggering warning lights and limp mode · more· less
The large DPF on the 3.0 V6 diesel requires regular highway driving at sustained speeds for passive regeneration. Cars used predominantly for urban and short-trip driving can clog the DPF after 80,000-100,000 km. Symptoms include check engine light, DPF warning messages, reduced power, and increased fuel consumption as the ECU attempts forced regeneration. Professional DPF cleaning costs €300-500; if the filter is beyond recovery, replacement runs €1,500-2,500. Regular 20-minute motorway drives help keep the filter clear. Using the correct low-ash engine oil reduces soot production.
AdBlue/SCR system faults (Euro 6 models)
€500 - 2,0008 of 8
NOx sensors, injector, or pump in the selective catalytic reduction system can fail · more· less
Euro 6 models (typically 2015+) use an AdBlue/SCR system to meet emissions standards. The NOx sensors, AdBlue injector, and supply pump can fail, triggering warning messages and eventually limiting engine restarts if not addressed. Sensor replacement costs €300-600; a complete SCR system overhaul can reach €1,500-2,000. Common symptoms include false "wrong AdBlue" warnings and countdown timers threatening engine lockout. Always use certified AdBlue and keep the system topped up. Wiring harness corrosion near the tank is a known contributing factor.
The VM Motori 3.0 V6 CRD can deliver 200,000+ km if maintained to specification, but the oil cooler, EGR cooler, and emissions hardware are documented weak points. FCA changed the specified oil from 5W-30 to 5W-40 on part of the 2016 build. Regular ZF gearbox fluid changes and monitoring the cooling system are essential. Cars with Quadra-Lift air suspension carry additional repair risk. Budget accordingly and prioritize preventive oil cooler inspection at every service.
Service history
Complete Jeep dealer or specialist records essential. Verify the oil grade specified for this VIN was used consistently.
Tires
Check tread depth, age (date codes), and uneven wear patterns indicating suspension or alignment problems.
Cold start
Must start engine completely cold. Listen for deep knocking sounds from the bottom end in the first 30 seconds.
Test drive
Minimum 30 minutes including motorway driving to check for gearbox shudder and DPF regeneration behaviour.
Specific for this vehicle
Inspect coolant for oil contamination
Check the coolant expansion tank carefully. Oil floating on the surface or discoloured milky coolant indicates oil cooler failure. This is the single most important check on this engine.
Verify EGR cooler recall completed (2014-2019)
Contact a Jeep dealer with the VIN to confirm recall W79 has been completed. Uncorrected EGR cooler cracking poses a fire risk.
Test all air suspension modes (if equipped)
Cycle through all Quadra-Lift height settings. The car should raise and lower smoothly and hold each level without sagging overnight.
+ 5 more checksShow less
Check gearbox fluid condition (post-2013 ZF 8HP)
Ask when the ZF 8HP fluid was last changed. If never changed, budget for an immediate service. Dark or burnt-smelling fluid indicates neglect.
Test for torque converter shudder
Drive at 40-70 km/h under light throttle. Any vibration or shuddering sensation indicates torque converter clutch wear.
Check all electrical systems and warning lights
On 2011-2013 models especially, test all electrical functions including windows, locks, horn, and fuel pump priming sound at key-on.
Check oil level and condition
The VM Motori V6 can consume oil. Verify level and that the oil is clean, consistent with the claimed service interval.
Verify AdBlue system status (Euro 6 models)
Check for any SCR-related warning messages or countdown timers. Test that the AdBlue level reads correctly and no fault codes are stored.
Recalls and Technical Service Bulletins
EGR cooler cracking and fire risk, recall W79 (2014-2019 3.0 CRD)Critical - verify completed
EGR cooler, later European campaign 03B (9 October 2018 - 2 June 2020 production)Critical - verify completed
Loss of crankshaft position reference, UK R/2025/485/66A (2014-2020 3.0 diesel)Verify completed
TIPM fuel pump relay malfunction (2011-2013 models)Verify if applicable
Contact a Jeep dealer with the VIN to verify all recalls have been completed. Two separate EGR cooler campaigns cover this engine, W79 for 2014-2019 cars and the later 03B action for late-2018 to mid-2020 production, and both address a fire risk. The high-pressure fuel pump and crankshaft-sensor campaigns cover most of the diesel's production run, so check by VIN rather than assuming a model year is clear. European recall designations differ from US NHTSA numbers.
Warranty Status
Factory warranty (2 years)Expired on all used WK2 models
Rust perforation warrantyCountry-specific, seven years in the UK (outer body panels) and Poland; expired on this generation
