The Chrysler ERM is a 3,604 cc, 60‑degree V6 petrol engine produced between 2015 and 2020. It features an aluminium block and heads, dual overhead camshafts (DOHC), and variable valve timing (VVT) on both intake and exhaust camshafts. This configuration delivers smooth, responsive power, with outputs typically rated at 220 kW (296 PS) and 353 Nm of torque.
Fitted to the Chrysler 300, Dodge Charger, and Jeep Grand Cherokee, the ERM engine was engineered for a blend of everyday drivability and spirited performance. Emissions compliance for its production period was achieved through precise electronic fuel injection and dual VVT, meeting stringent Euro 6 standards.
One documented engineering update addressed potential oil pump drive assembly failures in early production units. Chrysler Service Bulletin 15‑012‑17 recommended revised oil pump drive shaft and sprocket materials to improve durability, a modification implemented on engines produced after October 2017.

Production years 2015–2020 meet Euro 6 standards for applicable markets (VCA UK Type Approval #VCA/EMS/5682).
The Chrysler ERM is a 3,604 cc 60-degree V6 petrol engine engineered for full-size sedans and SUVs (2015-2020). It combines DOHC with dual variable valve timing to deliver strong, linear power and refined operation. Designed to meet Euro 6 standards, it offers a compelling mix of performance and efficiency for its class.

The dual VVT system provides excellent throttle response and fuel efficiency but requires strict adherence to 8,000-10,000 km oil change intervals using the specified 5W-20 viscosity to ensure proper phaser operation. The dual primary timing chains are generally robust, but tensioner wear can occur; listen for a rattle on cold start. Early production engines (pre-SIB 15-012-17) may be prone to oil pump drive assembly failures; inspect for low oil pressure warnings. Fuel injectors can develop deposits over time; periodic cleaning is recommended.
Oil Specs: Requires Chrysler specification MS-6395 (5W-20) (Chrysler Owner's Manual 2016). Critical for VVT operation.
Emissions: Euro 6 certification applies to all 2015–2020 ERM engines for EU/UK markets (VCA Type Approval #VCA/EMS/5682).
Power Ratings: Measured under SAE J1349 standards. Ratings apply to standard tune (Chrysler TIS Doc. V6-36L-04).

The Chrysler ERM was used across Chrysler's LX and WK2 platforms with longitudinal mounting. This engine received platform-specific adaptations-including unique engine mounts and accessory drive layouts for the 300 versus the Grand Cherokee-but remained largely consistent mechanically. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the left (driver's side) cylinder block, just below the cylinder head deck surface (Chrysler TIS V6-36L-04). The 8th VIN digit for ERM-equipped vehicles is typically 'G'. Visually, the engine is identifiable by its large, cast aluminium intake manifold and the "Pentastar" logo on the plastic engine cover. Critical differentiation from the earlier EZB engine: ERM features minor ECU and emissions calibrations for Euro 6 compliance, but shares the same core architecture. The presence of VVT solenoids on both the front and rear of the cylinder heads confirms the dual VVT system.
The ERM's primary reliability focus is on the variable valve timing (VVT) system and associated oil pressure, with elevated incidence in vehicles subjected to infrequent oil changes. Chrysler internal service data indicates VVT solenoid or phaser issues are a leading cause of check engine lights in high-mileage examples, while oil sludge buildup can exacerbate timing chain tensioner wear. Maintaining strict oil change intervals with the correct specification is critical.
