On the 2007-2018 Hyundai Santa Fe, 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.
Test alternator output with a multimeter (should be 13.8-14.5V at idle). Replace alternator if output is below 13V. OEM replacement (Hyundai part 37300-2G150 for V6 models). Aftermarket options from Denso or Valeo are reliable alternatives at lower cost. Budget $300-600 for parts and labor.

On the 2007-2020 Hyundai Santa Fe 3.3L V6, the alternator on the Santa Fe has a higher-than-average failure rate, often failing between 60,000-100,000 miles. The internal voltage regulator and rectifier are the typical failure points. A failing alternator causes dimming lights, battery drain, and eventually a no-start condition. The 3.3L V6 models seem particularly affected, possibly due to higher electrical loads from the larger engine bay accessories.
Replace the alternator. OEM Hyundai alternators and quality remanufactured units from Denso or Bosch are recommended. Avoid cheap rebuilds as they tend to fail again quickly. Test the battery at the same time, as a weak battery can overwork and kill a new alternator. Check the serpentine belt and tensioner condition during replacement.

On the 2007-2019 Hyundai Santa Fe, the Continuous Variable Valve Timing (CVVT) actuator and its associated oil control valve (OCV) on the Santa Fe's Theta II engine 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.
Replace the CVVT actuator (camshaft phaser) and the oil control valve. Clean the oil passages feeding the VVT system. Switch to a high-quality full synthetic oil and maintain strict oil change intervals (5,000 miles or less). In some cases, cleaning the OCV with throttle body cleaner can restore function temporarily, but replacement is the permanent fix.

VISIBILITY:WINDSHIELD
Hyundai Motor America (Hyundai) is recalling certain 2020-2021 Santa Fe, 2021 Sonata, and Elantra vehicles. During manufacturing, the windshield may not have been properly bonded to the vehicle, allowing it to detach in a crash.
TRAILER HITCHES
Hyundai Motor America (Hyundai) is recalling certain 2019-2023 Santa Fe, 2021-2023 Santa Fe HEV, 2022-2023 Santa Fe Plug-in HEV and Santa Cruz vehicles potentially equipped with a tow hitch harness installed as original equipment, or purchased as an accessory through a Hyundai dealership. Water accumulation on the tow hitch harness module printed circuit board (PCB) may cause an electrical short, which can result in a fire.
SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP:CONTROL UNIT/MODULE
Hyundai Motor America (Hyundai) is recalling certain 2016-2018 Santa Fe, 2017-2018 Santa Fe Sport, 2019 Santa Fe XL, and 2014-2015 Tucson vehicles. The Anti-Lock Brake System (ABS) module could malfunction and cause an electrical short, which could result in an engine compartment fire.
AIR BAGS:SIDE/WINDOW
Hyundai Motor America (Hyundai) is recalling certain 2019 Hyundai Santa Fe vehicles. The Side Curtain Air Bag (SCAB) mounting bolts may interfere with and damage the air bags during deployment.
TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS
Hyundai Motor America (Hyundai) is recalling certain 2017 Santa Fe Sport vehicles. The affected vehicles have a tire pressure monitoring system (TPMS) that may not have been set in the correct mode during vehicle assembly, and therefore will not provide an appropriate warning in the event of an underinflated tire. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 138, "Tire Pressure Monitoring Systems."
