The Jeep 552 63 842 is a 3,604 cc, V6 naturally aspirated petrol engine produced between 2011 and 2013. It features a 60‑degree V6 layout, dual overhead camshafts, and variable valve timing (VVT) on both intake and exhaust camshafts. This powertrain delivers 210 kW (285 PS) and 353 Nm of torque, with its high redline and linear power delivery engineered for responsive on — road performance.
Fitted exclusively to the Grand Cherokee (WK2) in markets like Europe and Australia,…
All production years (2011–2013) meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/9876).
The Jeep 552 63 842 is a 3,604 cc V6 naturally aspirated petrol engine engineered for flagship SUVs (2011-2013). It combines dual overhead camshafts with variable valve timing on both intake and exhaust to deliver smooth, linear power. Designed to meet Euro 5 standards, it balances strong performance with regulatory compliance.

The Jeep 552 63 842 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 intake manifold runner for the Grand Cherokee. All adaptations are documented in OEM technical bulletins.
The 552 63 842's primary reliability focus is on the variable valve timing (VVT) solenoids, with elevated failure rates noted in high-mileage vehicles where oil changes were extended. Stellantis internal data indicates this is a common cause of check engine lights, while UK DVSA records show minimal MOT failures related to the engine. Using the correct oil viscosity and adhering to service intervals are critical preventative measures.
Analysis derived from Stellantis technical bulletins (2011-2013) 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 63 842 is generally a robust and durable engine. Its main long-term considerations are the VVT solenoids and water pump, which are common wear items. With regular oil changes using the correct 5W-20 specification and timely replacement of these components, the engine can easily exceed 200,000 miles with no major issues.
The most frequently reported issues are failures of the Variable Valve Timing (VVT) solenoids causing check engine lights, leaks from the external oil cooler lines, failure of the intake manifold runner control (IMRC) motor, and eventual water pump failure. These are generally straightforward and inexpensive fixes.
The 552 63 842 engine was used exclusively in the Jeep Grand Cherokee (WK2 generation) from model years 2011 to 2013. It was the standard petrol V6 engine for this model before being updated to a more efficient variant. It was not used in the Cherokee (KL) or any other Jeep platform.
Yes, the engine responds well to basic ECU remapping, which can yield modest gains of 10-20 kW and improved throttle response. More significant power increases require hardware modifications like a performance intake, exhaust, and potentially camshafts. The naturally aspirated design has less tuning potential than a turbocharged engine.
Official combined WLTP figures are around 10.5 L/100km (27 mpg UK). Real-world consumption varies: expect 12-14 L/100km (20-24 mpg UK) in mixed driving, and 9-10 L/100km (28-31 mpg UK) on long highway runs. Fuel economy is heavily influenced by the vehicle's weight and driving style.
Yes. The 552 63 842 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 very robust and designed to last the engine's lifetime under normal operating conditions.
The engine requires Stellantis MS-6395 specification 5W-20 synthetic oil. Using the correct low-viscosity oil is crucial for the proper operation of the variable valve timing system, fuel economy, and overall engine longevity. The recommended service interval is typically 12,500 km or 12 months.
