Overview
The DM (third-gen, sometimes badged 'Santa Fe Series II' after the late-2015 facelift) was Australia's volume-selling medium-large SUV alternative to the Toyota Kluger and Mazda CX-9, and unlike most markets the AU DM was exclusively a seven-seater. It is a soft-roader monocoque crossover with on-demand AWD (or FWD) and no low range - a family wagon, not a serious off-roader. The lineup ran Active, Elite and Highlander grades. The vast majority sold were the 2.2L R-series D4HB turbo-diesel auto, which dominated the range; a 2.4L Theta II petrol (manual or auto, the cheap entry point) and a rare 3.3L Lambda II V6 petrol (FWD-only, the smoothest and arguably most reliable but very thirsty) round it out. Buy on history: the diesel's CP4 fuel system, DPF/EGR and a genuinely common rear-differential/AWD-coupling failure are the things that bite, while the 2.4 petrol carries Hyundai/Kia's Theta II rod-bearing reputation. A 2015-17 engine-bay fire recall (faulty electronics) and a 2018 steering-coupling recall also apply - confirm both are done.

Pros
- Strong low-down torque (436Nm) - the pick for towing and a loaded 7-seater
- Good real-world economy for a heavy SUV
- By far the most common DM, so parts and specialists are easy
- Generally durable bottom end if serviced on clean fuel and oil
Cons
- Clattery, noisy diesel - visible black smoke under hard acceleration
- Bosch CP4 pump and piezo injectors are intolerant of poor/contaminated fuel
- DPF and EGR dislike short urban-only running and clog over time
- Shares the DM's well-documented rear-diff / AWD-coupling failure risk
Known problems
high
Rear differential / AWD coupling failure
A genuinely common DM complaint: the rear differential and/or the electronic AWD coupling fails, with whine, vibration, banging and warning lights. Owners report bills from ~$3900 for a rear diff up to $8600+ when front and rear are both done, and isolated cases over $11,000. Often traced to a weak diff housing/coupling design and to running mismatched-wear or differently-sized tyres on the on-demand AWD.
Fix: Replace the rear diff / coupling unit. Pre-purchase: listen for driveline whine, rotate to identical tyres across all four corners, and budget for it on AWD examples.
high
Bosch CP4 pump / piezo injector failure (bad fuel)
The CP4 high-pressure pump and piezo injectors do not tolerate water-contaminated or poor-quality diesel; pump self-destruction can send metal debris through the whole common-rail system, requiring fuel-system replacement, not just the pump.
Fix: Use clean fuel, change filters on schedule, fit a quality pre-filter/water separator for rural/touring use. On failure, full fuel-system clean and replacement by a diesel specialist.
medium
DPF clogging and EGR valve carbon
The close-coupled DPF and the EGR valve/cooler soot up - the EGR commonly by around 100,000km - causing warning lights, limp mode and incomplete regens, especially on short urban-only trips.
Fix: Regular highway runs to complete regens; EGR clean/replace; DPF clean or forced regen. Confirm no active DPF lights pre-purchase.
medium
Harmonic balancer / crank thrust and turbo actuator
Reported D4HB ancillary issues include harmonic-balancer (crank pulley) wear, crank thrust-bearing wear on manuals, and VGT turbo actuator sticking causing over/under-boost and power loss.
Fix: Replace the harmonic balancer; inspect/clean or replace the VGT actuator; diesel-specialist diagnosis for boost faults.

Pros
- Cheapest way into a DM Santa Fe, manual available
- Quieter and smoother than the diesel, no DPF/EGR complexity
- Simple, well-understood Theta II - cheap routine parts
Cons
- Underpowered hauling a heavy seven-seat AWD wagon
- Carries the Hyundai/Kia Theta II rod-bearing failure reputation
- Notable oil consumption on some examples
- Thirstier than rivals' lighter four-cylinders when worked
Known problems
high
Theta II connecting-rod bearing failure
The 2.4 Theta II family is subject to premature connecting-rod bearing wear linked to machining debris restricting oil passages and oil-flow inconsistency. Symptoms are an rpm-rising knock, oil-pressure and check-engine lights, power loss and vibration; severe failures can hole the block and create a fire risk. This drove a large multi-year Hyundai/Kia campaign and extended warranties overseas.
Fix: Engine replacement on failure. Check service history for the knock-sensor detection software update and any engine campaign; pre-purchase oil-pressure and cold-start listening; watch oil level.
medium
Oil consumption
Some Theta II 2.4 engines consume oil noticeably between services, which both annoys and accelerates bearing wear if the level is allowed to drop.
Fix: Check and top up oil between services; investigate rings/PCV if consumption is heavy.
low
Water pump / thermostat housing leaks
Water pump and thermostat-housing weeping are common cooling-system maintenance items on these engines.
Fix: Replace water pump and thermostat housing/gasket; refresh coolant.

Timing chain / belt / gear
Chain-driven
Pros
- Smoothest, strongest and arguably most reliable DM engine
- No diesel emissions complexity and avoids the Theta II rod-bearing reputation
- Effortless, quiet performance for a family seven-seater
Cons
- Very rare in Australia and FWD-only - no AWD traction
- The thirstiest engine in the range
- Limited torque low down versus the diesel for towing
Known problems
medium
Oil consumption
Oil consumption is the most common complaint on the Lambda II V6; keep the level up to avoid secondary wear.
Fix: Monitor and top up oil between services; investigate PCV/rings if heavy.
medium
Timing chain components at high km
Occasional timing-chain guide/tensioner complications are reported at higher mileage, signalled by cold-start rattle.
Fix: Investigate cold-start chain rattle; replace chain, guides and tensioners as a set if worn.
low
Fuel thirst
Real-world 12-14 L/100km in a heavy seven-seater; not a fault but the trade-off for V6 smoothness.
Fix: Accept the fuel bill, or choose the diesel for economy.
Common problems (all variants)
high
Engine-bay fire recall (2015-2017 electronics)
Around 8,700 DM Santa Fes (2015-17 build) were recalled in Australia over an engine-bay fire risk caused by a faulty circuit board/electrical component. Affected vehicles should have been rectified, but verify.
Fix: Confirm the recall has been completed against the VIN at a Hyundai dealer.
high
Steering / intermediate-shaft coupling recall (2018)
A recall covered a steering-coupling concern (risk of steering separation). It must be confirmed complete before purchase.
Fix: Check the VIN for outstanding recalls at a Hyundai dealer and have any open item rectified.
medium
Air-conditioning / climate faults
Owners report A/C and climate-control malfunctions including weak cooling and compressor/condenser issues, common in Australian heat.
Fix: Diagnose the system; recharge, repair leaks, or replace compressor/condenser as needed.
low
Electrical gremlins and warning lights
Assorted electrical faults - dash warning lights, sensors, infotainment and wiring niggles - are reported across the DM range.
Fix: Scan for fault codes and address the specific sensor/module; verify all warning lights are off pre-purchase.
low
Suspension and wheel-bearing wear
Wheel bearings, control-arm bushes and links wear on a heavy seven-seat SUV, giving hums, clunks and uneven tyre wear.
Fix: Replace worn bearings/bushes; wheel alignment after suspension work.
