The Jeep 552 63 087 was developed by Fiat Powertrain for Jeep's WK2 platform with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts and a unique exhaust routing for the Grand Cherokee. All adaptations are documented in OEM technical bulletins.
The 552 63 087's primary reliability focus is on the EGR cooler, with elevated failure rates noted in high-mileage vehicles under towing conditions. Stellantis internal data indicates this is the most common warranty claim for this engine, while UK DVSA records show DPF-related issues as a frequent MOT advisory item. Regular highway driving and using the correct oil make preventative maintenance critical.
Analysis derived from Stellantis technical bulletins (2014-2019) and UK DVSA failure statistics (2018-2024). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The 552 63 087 is a powerful and generally robust engine, but its long-term reliability hinges on proactive maintenance, particularly of the EGR cooler and DPF system. Vehicles used primarily for highway driving and towing tend to fare better. Addressing EGR cooler leaks early and ensuring regular DPF regeneration are key to avoiding major repairs.
The most frequently documented issues are EGR cooler internal failures leading to coolant contamination, DPF clogging from insufficient regeneration, turbo actuator faults causing boost issues, and leaking fuel injector seals. These are covered in detail in Stellantis service bulletins.
The 552 63 087 engine was used exclusively in the Jeep Grand Cherokee (WK2 generation) from model years 2014 to 2019. It was marketed as the '3.0 CRD' and was the primary diesel option for this flagship SUV in markets outside North America.
Yes, the engine responds well to ECU remapping, with Stage 1 tunes typically adding 30-50 kW and 100+ Nm of torque. The stock internals, including the turbo and injectors, can handle this increase. However, aggressive tuning increases stress on the EGR and DPF systems, potentially accelerating wear. Supporting modifications like an upgraded intercooler are recommended for higher stages.
Official combined WLTP figures are around 7.5 L/100km (38 mpg UK). Real-world consumption varies significantly: expect 9-11 L/100km (26-31 mpg UK) in mixed driving, and 6.5-7.5 L/100km (38-43 mpg UK) on long highway runs. Towing or aggressive driving will increase consumption substantially.
Yes. The 552 63 087 is an interference engine. This means if the timing chain were to fail or jump, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the timing chain is designed to last the engine's lifetime under normal operating conditions.
The engine requires Stellantis MS-12991 specification 5W-40 synthetic oil. Using the correct oil is vital for protecting the turbocharger, maintaining DPF function, and ensuring proper lubrication under high thermal loads. The recommended service interval is typically 20,000 km or 12 months.
