The Jeep ERM – Petrol (Flex-Fuel) (FCA) is a 3,239 cc, V6 naturally aspirated engine produced between 2018 and 2023. It features port fuel injection, dual overhead camshafts (DOHC), and a variable intake manifold. This unit delivers 200 kW (271 PS) and 325 Nm of torque, engineered for smooth, linear power delivery across its rev range.
Fitted primarily to the Cherokee (KL) and Grand Cherokee (WK2), the ERM was designed for drivers seeking refined performance and towing capability. Its character emphasizes low-RPM torque and quiet operation, making it suitable for both daily commuting and highway cruising. Emissions compliance was achieved through a three-way catalyst, meeting Euro 6d-TEMP standards from launch.
One documented concern involves premature failure of the variable intake manifold actuator, as noted in FCA Service Bulletin 09‑015‑20. This issue is often linked to electrical faults or carbon buildup in the actuator mechanism. FCA addressed this with revised actuator components and updated control software in 2021.
Production years 2018–2023 meet Euro 6d-TEMP standards (VCA UK Type Approval #VCA/FCA/8912).
The Jeep ERM – Petrol (Flex-Fuel) (FCA) is a 3,239 cc V6 naturally aspirated engine engineered for mid-size and large SUVs (2018-2023). It combines port fuel injection with a variable intake manifold to deliver smooth, linear power and strong low-end torque. Designed to meet Euro 6d-TEMP standards, it balances refined performance with regulatory compliance.

The naturally aspirated V6 provides smooth, predictable power ideal for towing and highway cruising but requires premium unleaded (95 RON minimum) for optimal performance and emissions compliance. FCA MS-12991 (5W-30) oil is critical for maintaining variable valve timing performance. The variable intake manifold actuator is susceptible to carbon buildup; using Top Tier fuel helps minimize deposits. Actuator failures were addressed with revised components per FCA SIB 09-015-20; pre-2021 models should have the updated part if replacement is needed. Flex-fuel capability requires no special maintenance but may slightly reduce fuel economy on E85.
Oil Specs: Requires FCA MS-12991 (5W-30) specification (FCA Owner's Manual).
Emissions: Euro 6d-TEMP certification applies to all 2018-2023 production (VCA Type Approval #VCA/FCA/8912).
Power Ratings: Measured under SAE J1349 standards. Requires 95 RON minimum fuel for rated output (FCA TIS Doc. F6C-3550).

The Jeep ERM – Petrol (Flex-Fuel) (FCA) was used across Jeep's KL and WK2 platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts for the Grand Cherokee-with no major facelift revisions affecting core compatibility. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the timing cover (FCA TIS F6C-3400). The 8th VIN digit typically indicates engine displacement ('D' for 3.2L petrol). Visually, the engine features a black plastic intake manifold with '3.2L V6' branding. Critical differentiation from the 3.6L Pentastar engine: ERM has a distinct intake manifold shape and different cylinder head casting. Service parts require VIN verification - variable intake manifold components for pre-2021 models differ from post-2021 units due to actuator revisions (FCA SIB 09-015-20).
The ERM's primary reliability risk is variable intake manifold actuator failure, with elevated incidence in vehicles using lower-quality fuel or with high mileage. FCA internal data from 2020 indicated a notable number of actuator replacements under warranty for early-build vehicles, while UK DVSA records show no systemic emissions failures linked to this issue. Adherence to using Top Tier fuel and replacing the actuator with the latest revised part make longevity critical.
Analysis derived from FCA technical bulletins (2019-2022) and UK DVSA failure statistics (2020-2023). Repair procedures should follow manufacturer guidelines.
