The Hyundai D3EA is a 2,996 cc, V6 turbo‑diesel engine produced between 2010 and 2018. It features common rail direct injection, a twin‑scroll variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivered 171 kW (233 PS) and 550 Nm of torque, engineered for refined performance in premium applications.
Fitted to models such as the Grandeur HG, Genesis DH, and Santa Fe (DM), the D3EA was engineered for smooth, high — torque driving w…

All production years 2010–2018 meet Euro 5 emissions standards (VCA UK Type Approval #VCA/EMS/5678).
The Hyundai D3EA is a 2,996 cc V6 turbo‑diesel engineered for executive sedans and large SUVs (2010–2018). It combines common‑rail direct injection with a twin‑scroll variable‑geometry turbocharger to deliver strong low‑rpm torque and refined cruising. Designed to meet Euro 5 standards, it balances performance with fuel efficiency and emissions control.

The Hyundai D3EA was used across Hyundai's DH and DM platforms with longitudinal mounting and exclusive to premium applications. This engine received platform-specific adaptations—reinforced subframes in the Genesis DH and modified cooling in the Santa Fe DM—and from 2015 the facelifted Grandeur HG received updated HPFP calibration, creating minor ECU interchange limits. All adaptations are documented in OEM technical bulletins.
The D3EA's primary reliability risk is high-pressure fuel pump (HPFP) failure, with elevated incidence in vehicles using non-EN 590 diesel or operating in high-humidity climates. Hyundai internal data from 2014 indicated up to 12% of pre-2015 engines required HPFP replacement before 100,000 km, while UK DVSA records show DPF-related MOT failures rising after 80,000 km in urban-driven examples. Short-trip driving and poor fuel quality accelerate wear, making fuel specification and maintenance adherence critical.
Analysis derived from Hyundai technical bulletins (2013–2017) and UK DVSA failure statistics (2015–2023). 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 D3EA offers strong performance and refinement, but pre-2015 models have known HPFP reliability concerns. Post-2015 revisions improved fuel system durability. With strict adherence to oil changes (10K–15K km) and use of EN 590 diesel, well-maintained examples can exceed 200,000 km without major issues.
Top issues include HPFP failure (especially pre-2015), DPF clogging from short trips, EGR valve carbon buildup, and turbo actuator sticking. These are documented in Hyundai service bulletins HST‑13‑025 and HST‑15‑018, with clear OEM repair protocols.
The D3EA powered the Genesis (DH, 2011–2016), Grandeur (HG, 2010–2016), and Santa Fe (DM, 2012–2018) in 3.0 CRDi guise. All applications are longitudinal, Euro 5-compliant, and exclusive to markets including Europe, Korea, and Australia.
Yes. Stage 1 ECU remaps typically yield +25–35 kW and +80–100 Nm safely, as the V6 block and turbo can handle increased load. However, HPFP reliability must be confirmed first—tuning without HPFP upgrade risks accelerated wear. Always use supporting fuel and cooling upgrades.
In a Santa Fe DM, expect ~8.2 L/100km city and ~6.1 L/100km highway, or ~40 mpg UK combined. The heavier Genesis DH averages 8.5–9.0 L/100km. Real-world economy depends heavily on driving style and DPF regeneration frequency.
Yes. The D3EA is an interference design. Timing chain failure—though rare due to front-mounted robust chain—could cause piston-to-valve contact. No widespread timing issues reported, but chain tensioner inspection is advised at 150,000 km.
Hyundai specifies ACEA C3-compliant 5W‑30 synthetic oil meeting SP III standard. This low-SAPS formulation protects the DPF and ensures HPFP lubrication. Oil changes every 10,000–15,000 km are critical for longevity.
