The Jeep 552 83 099 is a 2,987 cc, V6 turbo‑diesel engine produced between 2014 and 2019. It features a 60‑degree V6 layout with dual overhead camshafts and a variable geometry turbocharger (VGT), delivering robust low‑end torque suitable for towing and off‑road applications. In standard form it produced 184 kW (250 PS) and 600 Nm of torque, an evolution of the earlier 552 63 113 variant.
Fitted primarily to the WK2 Grand Cherokee and the Dodge Durango, this engine was engine…
All production years 2014–2019 meet Euro 6 emissions standards (VCA UK Type Approval #VCA/EMS/5679).
The Jeep 552 83 099 is a 2,987 cc V6 turbo-diesel engineered for large SUVs (2014–2019). It combines a high-pressure common-rail fuel system with a variable-geometry turbocharger to deliver strong, sustained torque for towing and off-road use. Designed to meet Euro 6 standards, it prioritizes power and emissions compliance.

The Jeep 552 83 099 was used in Jeep and Dodge large SUV platforms with longitudinal mounting. This engine is a direct successor to the 552 63 113, featuring updated ECU calibrations and emissions hardware for Euro 6 compliance. No major platform-specific mechanical revisions were introduced. All adaptations are documented in OEM technical bulletins.
The 552 83 099's primary reliability risk is EGR cooler failure, with elevated incidence in vehicles subjected to frequent short trips or extreme thermal cycling. Fiat Powertrain SIB 09-015-17 documents this as a leading cause of coolant-related warranty claims, while owner reports frequently cite overheating. Preventative inspection of the EGR cooler and adherence to highway driving cycles for DPF regeneration are critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 552 83 099 is a powerful and refined engine, but its long-term reliability hinges on maintenance and driving habits. The EGR cooler is a known weak point. Vehicles with good service records, using the correct oil and high-quality diesel, and driven regularly on highways for DPF regeneration can be very dependable. Neglect significantly increases failure risk.
The most frequent and critical issue is failure of the EGR cooler, leading to coolant loss and potential engine damage. Other common problems include high-pressure fuel pump (HPFP) failure, turbocharger actuator issues, and DPF clogging due to insufficient regeneration on short trips. These are well-documented in Fiat Powertrain service bulletins.
This 3.0L V6 diesel was used in the Jeep Grand Cherokee (WK2) from 2014 to 2019, primarily in higher trims like Limited, Overland, and Summit. It was also available in the Dodge Durango for the 2014-2016 model years. It was not used in the smaller Cherokee (KL) or Compass models.
Yes, ECU remapping is common and can yield significant power and torque gains (e.g., +30-50 kW). The engine's internals are robust. However, increased power puts more stress on the transmission, turbocharger, and emissions systems (EGR, DPF). Any tuning should be accompanied by supporting modifications and more frequent maintenance, especially for the EGR cooler.
Fuel economy is moderate for its size and power. Expect real-world figures around 10.0-12.0 L/100km (28-24 mpg UK) for mixed driving in a Grand Cherokee. Highway cruising can achieve 8.0-9.0 L/100km (35-31 mpg UK), while heavy towing or city driving will increase consumption significantly. DPF regeneration cycles also temporarily increase fuel use.
Yes. Like virtually all modern engines, the 552 83 099 is an interference design. If the timing chain were to fail (though this is not a common failure point for this engine), the pistons would collide with the valves, causing catastrophic internal engine damage.
It requires a specific 5W-40 synthetic oil meeting the MS-10902 specification. Using the correct oil is critical for protecting the turbocharger, emissions systems, and high-pressure fuel pump. Oil should be changed at intervals not exceeding 15,000 km or 12 months, whichever comes first.
