2007-2025 Hyundai Santa Fe Problems: 17 Known Issues

The 2.0L Theta II turbo (G4KH) in the Santa Fe Sport uses a banjo-bolted oil feed hose to the turbocharger center section. The hose assembly and its sealing washers leak, and heat-soak after shutdown cokes the oil inside the small-diameter feed line, restricting flow to the turbo bearing. Owners report oil pooling on the turbo housing and burning smell first, then turbo shaft-bearing noise (whine/whistle), smoke, and loss of boost. Hyundai issued service campaign/TSB 16-01-071 in December 2016 covering 2013-2016 Santa Fe Sport 2.0T for a leaking turbo oil feed hose assembly. Because the same engine is a known oil consumer, a low crankcase level compounds the starvation.

NHTSA recall 17V-226 (Hyundai recall 162) covers certain model-year 2013-2014 Santa Fe Sport vehicles equipped with 2.0-liter or 2.4-liter gasoline-direct-injection engines. Residual debris from factory machining can restrict oil flow to the main bearings and cause premature bearing wear. A worn connecting-rod bearing can produce cyclic engine knock or illuminate the oil-pressure lamp; if the bearing fails, the vehicle can lose motive power while moving.

NHTSA recall 20V-746 (Hyundai recall 198) covers certain model-year 2012 Santa Fe vehicles equipped with the 2.4-liter Theta II MPI engine. Conditions in the engine can cause premature connecting-rod-bearing wear. Continued operation with a worn bearing can damage the engine and eventually stall the vehicle; in limited cases, a damaged connecting rod can puncture the engine block, release oil onto hot components and increase fire risk.

Hyundai TSB 23-EM-008H provides inspection and repair guidance for vehicles with engine-oil-consumption concerns. Its parts and labor tables include model-year 2013-2018 Santa Fe Sport and 2019-2020 Santa Fe vehicles with the 2.4-liter GDI engine. The bulletin notes that some oil consumption is normal and does not assign one universal cause; it directs technicians to resolve leaks, abnormal engine noise, relevant campaigns or diagnostic faults before measuring consumption.

The Continuous Variable Valve Timing (CVVT) actuator and its associated oil control valve (OCV) on the Santa Fe's engines (the 2.7L Mu and 3.3L Lambda V6s and, from 2010, the Theta II four-cylinder) can fail, causing rough idle, poor fuel economy, and check engine lights. The OCV gets clogged with sludge from extended oil change intervals, and the CVVT actuator's internal components wear out. This issue can also trigger timing-related fault codes and affect emissions.

NHTSA recall 23V-181 (Hyundai recall 244) covers model-year 2019-2023 Santa Fe vehicles that may have a Hyundai accessory tow-hitch harness, including listed hybrid and plug-in-hybrid populations. The tow-hitch-harness module circuit board can be susceptible to water entering through the 4-pin tow-hitch harness connector. An electrical short can cause a trailer-harness-module fire while driving or while parked with the ignition off.

Alternators in Santa Fe models fail prematurely, often between 60,000-100,000 miles. The voltage regulator or rectifier diodes fail, causing undercharging, battery drain, and eventually no-start conditions. Some owners report multiple alternator replacements within the vehicle's life.

The rear subframe on second-generation Santa Fe models (especially in salt-belt states) is prone to severe corrosion that can compromise structural integrity. The steel subframe traps moisture and road salt, accelerating rust from the inside out. In extreme cases, the subframe can crack or separate, which is a critical safety concern.

The intermediate steering shaft on 4th-gen Santa Fe models develops a clunking or popping noise when turning the steering wheel, especially at low speeds or when going over bumps while turning. The universal joint in the shaft dries out and develops play. Hyundai has not issued an intermediate-shaft bulletin; its steering-column noise TSBs for the 2019 Santa Fe (20-ST-003H, 21-ST-003H, 22-ST-005H) address bearing noise in the MDPS column worm shaft, which should be ruled out first.

NHTSA recall 22V-056 (Hyundai recall 218) covers certain model-year 2017-2018 Santa Fe Sport and Santa Fe vehicles not equipped with Smart Cruise Control. The ABS module can malfunction internally and cause an electrical short over time. Significant overcurrent can increase the risk of an engine-compartment fire while the vehicle is parked or being driven. Hyundai stated that it was still investigating the root cause in the Part 573 filing.

Hyundai recalled certain 2021-2022 Santa Fe Hybrid (TM HEV) and 2022-2023 Santa Fe Plug-In Hybrid (TM PHEV) vehicles because the front driver and/or passenger seat belt pretensioners contain pyrotechnic charges that can deploy abnormally in a crash. Instead of retracting the belt cleanly, the pretensioner can rupture and project metal fragments into the occupant compartment, injuring the very occupants the belt is restraining. Affected HEV vehicles were built 12/18/2020 through 07/26/2022 and PHEV vehicles 05/13/2021 through 07/21/2022. This is NHTSA recall 22V-816 / Hyundai campaign 238; owner notification letters were mailed December 14, 2022. It is part of a wider Hyundai pretensioner recall family that also covered Accent and Elantra.

On the 2.5L Smartstream GDI+MPI engine (G4KN) used in the TM Santa Fe from 2021, the internal filter/screen inside the direct injector can break apart and the injector leaks fuel into the cylinder after shutdown and at idle. Owners report a hard hot start, raw-fuel smell, rough idle, single- or multi-cylinder misfires, loss of power and stalling while driving; the leaking fuel also dilutes the engine oil. Hyundai addressed it with TSB 23-FL-002H-1, which lists the diagnosis and replacement procedure for internally leaking GDI injectors and was later expanded to a wider production date range covering Santa Fe, Tucson and Santa Cruz. A 2025 class action alleges Hyundai has still not recalled the vehicles. Note the earlier 2.4L Theta II GDI injectors are a different part and this pattern is specific to the 2.5L.

Certain US-market 2024 Santa Fe vehicles built at HMMA from April 23 through July 2, 2024 are included in Recall 263 / 24V-529. Incorrect clutch commands can damage the transmission case or parking mechanism and permit rollaway in Park. Other shifting complaints need separate diagnosis; they do not prove this damage.

The panoramic sunroof drain tubes on the Santa Fe clog with leaves, pollen, and debris, causing water to overflow the sunroof tray and leak into the cabin. Water typically enters through the headliner area and drips onto the front seats or pools in the rear footwells. Extended water intrusion can damage the body control module, amplifier, or other electronics located under the carpet.

Santa Fe (and Santa Fe Sport) panoramic sunroofs have repeatedly shattered spontaneously, with no impact, often described by owners as sounding like a gunshot. Tempered glass tensioned over the large panoramic opening, combined with edge stress and ceramic-frit weakening, fails suddenly and rains broken glass into the cabin. Hundreds of NHTSA complaints and a class action (Glenn v. Hyundai, settled) followed, with multiple owners reporting that even the replacement glass later shattered.

The power transfer unit (PTU) on AWD Santa Fe models develops seal leaks, leading to fluid loss and eventual bearing damage. A whining noise from the front of the drivetrain is the first sign. If fluid runs low, the PTU gears can be damaged, requiring expensive replacement. The output shaft seal is the most common failure point.

Santa Fe paint, especially white/pearl-white and Hyundai's 'Scratch Recovery' self-healing clear coat, is prone to delamination — the clear coat and color coat lose adhesion to the layer beneath and begin peeling, flaking, or bubbling off in sheets, accelerated by UV exposure. It usually starts on horizontal surfaces (roof, hood) and spreads. A 2016 class action alleged the defect on 2006-2016 Hyundai models but was dismissed in 2017, and Hyundai issued white-paint warranty extensions for certain years.
