The Jeep EJK is a 2,996 cc, V6 naturally aspirated petrol engine produced from 2019 to present. It features a dual overhead camshaft (DOHC) design with variable valve timing, port fuel injection, and a composite intake manifold. This powerplant delivers 210 kW (285 PS) and 353 Nm of torque, utilizing its large displacement and optimized breathing for smooth, linear power delivery ideal for highway cruising and light towing.
Fitted primarily to the Grand Cherokee and Wran…

All production years 2019–Present meet Euro 6d standards for petrol engines (VCA UK Type Approval #VCA/EMS/9123).
The Jeep EJK is a 2,996 cc V6 naturally aspirated petrol engineered for mid-to-full-size SUVs (2019-Present). It combines port fuel injection with DOHC and variable valve timing to deliver smooth, linear power and refined operation. Designed to meet Euro 6d standards, it balances effortless performance with proven reliability.

The Jeep EJK was used across Jeep's Grand Cherokee and Wrangler platforms with longitudinal mounting. This engine received platform-specific adaptations-minor ECU calibrations for vehicle weight and gearing-and no significant facelift revisions have occurred during its production, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
The EJK's primary documented service concern is minor oil consumption in early production units, with no incidence of widespread mechanical failure. FCA Service Bulletin 20-055-20 addresses this for specific 2019-2020 builds, while general owner feedback indicates strong overall reliability. Use of correct oil specification makes long-term durability highly predictable.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the EJK is widely regarded as a very reliable and durable engine. The most common documented issue is higher oil consumption in early 2019-2020 builds, addressed by a piston ring update. With proper maintenance, using the correct 5W-30 oil, these engines are known for their smooth operation and longevity, often exceeding 250,000 km without major issues.
The primary documented issue is higher oil consumption in early builds (SIB 20-055-20). Other potential concerns include VVT solenoid failures, coolant leaks from the thermostat housing, and IMRC actuator issues. These are generally minor, repairable faults and not indicative of widespread engine failure.
The 3.0L naturally aspirated V6 EJK petrol engine is used in the Jeep Grand Cherokee (WL, 2019-Present) and the Jeep Wrangler (JL, 2020-Present). It is typically badged as '3.0 V6' or 'V6 Pentastar' in these vehicles across global markets.
Yes, but gains are modest due to its naturally aspirated design. ECU remapping can yield around 10-15 PS and 20-30 Nm by optimizing ignition and fuel maps. More significant gains require hardware modifications like a performance intake, exhaust, and camshafts, but the cost-to-gain ratio is often less favorable than with turbocharged engines.
Official combined figures are around 10.5-11.5 L/100km (25-27 mpg UK) for the Grand Cherokee and 11.0-12.0 L/100km (24-26 mpg UK) for the Wrangler. Real-world mixed driving typically yields 12.0-14.0 L/100km (20-24 mpg UK), depending heavily on vehicle, drivetrain, and driving style.
Yes. Like virtually all modern engines, the EJK is an interference design. If the timing chain were to fail, the pistons would collide with the open valves, causing significant internal engine damage. Fortunately, the chain is very durable with proper oil maintenance.
FCA specifies engine oil meeting the MS-6395 standard, typically a 5W-30 full synthetic. Using the correct specification is crucial for protecting the timing chain, VVT system, and ensuring overall engine longevity. Change intervals should not exceed 15,000 km or 12 months.
