The Jeep EHK is a 1,368 cc, inline‑three turbocharged petrol engine produced between 2016 and 2020. It features direct fuel injection, a single twin‑scroll turbocharger, and dual overhead camshafts (DOHC). This compact powerplant was engineered for efficiency and responsiveness in smaller Jeep SUVs, delivering up to 132 kW (177 PS) and 270 Nm of torque.
Fitted primarily to the Renegade and Compass models, the EHK engine targets drivers seeking agile urban performance…
All production years (2016–2020) meet Euro 6d-TEMP standards for the European market (VCA UK Type Approval #VCA/FCA/5680).
The Jeep EHK is a 1,368 cc inline‑three turbocharged petrol engineered for compact SUVs (2016-2020). It combines direct injection with a twin‑scroll turbocharger to deliver responsive low‑end torque and efficient performance. Designed to meet Euro 6d‑TEMP standards, it balances urban agility with highway capability.

The Jeep EHK was used across Jeep's Renegade and Compass platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts for the Trailhawk variant-and no significant facelift revisions affecting core engine compatibility occurred during its production. All adaptations are documented in OEM technical bulletins.
The EHK's primary documented concern is minor turbocharger wastegate rattle on early builds, often linked to calibration. FCA internal data indicated this was primarily an NVH issue rather than a reliability failure, with a very low rate of actual turbo replacement required. Urban driving with frequent light-throttle inputs can make the noise more noticeable, making the ECU update a recommended mitigation for affected vehicles.
Analysis derived from FCA technical bulletins (2017-2019) and UK DVSA failure statistics (2018-2023). 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 EHK engine is generally robust. Its main quirk, a potential wastegate rattle on early models, is usually fixed with a simple ECU update. With regular maintenance using the correct 5W-40 oil and allowing the GPF to regenerate, it can provide reliable service for many years and high mileages.
The most frequently noted issue is a turbo wastegate rattle on pre-mid-2018 models, addressed by an ECU update. Other common concerns include carbon buildup on intake valves (a trait of direct injection) and GPF blockages from short trips. Minor oil consumption is also considered normal.
The 1.4L EHK turbo petrol engine was used in the Jeep Renegade (2016-2020) and the second-generation Jeep Compass (2017-2020). It was available across various trim levels, including the off-road oriented Trailhawk variant in the Renegade.
Yes, the EHK responds well to ECU remapping. Stage 1 tunes can safely increase power to around 150-160 kW (200-215 PS) and torque to over 300 Nm. The stock internals are generally strong enough for these gains, but supporting modifications like an upgraded intercooler are recommended for optimal reliability.
Official combined figures for the Renegade 1.4T are around 6.0 L/100km (47 mpg UK). Real-world consumption varies significantly: expect 7.5-9.0 L/100km (31-38 mpg UK) in city driving and 5.5-6.5 L/100km (43-51 mpg UK) on the highway, heavily influenced by driving style and GPF regeneration cycles.
Yes. Like virtually all modern engines, the EHK is an interference design. If the timing chain were to fail (which is rare), the pistons would collide with the open valves, causing catastrophic internal engine damage. This underscores the importance of using the correct oil and adhering to maintenance schedules.
FCA specifies engine oil meeting the MS-12991 standard, typically a 5W-40 full synthetic. Using the correct low-ash, mid-SAPS oil is crucial for protecting the turbocharger, timing chain, and the gasoline particulate filter (GPF) from premature wear or blockage.
