On the 2022-2024 Hyundai Tucson, nHTSA recall 25V-893 covers certain model-year 2022-2024 Hyundai Tucson vehicles equipped with an optional OEM trailer wiring harness installed as a port-installed or dealer-installed option. The harness control module was installed in a location susceptible to water ingress and has insufficient sealing. Water inside the module can make trailer or vehicle stop lamps inoperative or, in rare cases, cause a short that can overheat, melt or ignite, increasing crash and fire risk. Intermittent or inoperative parking, turn-signal, or stop lamps on the vehicle or trailer may provide warning.

Common Symptoms

  • Intermittent or inoperative vehicle or trailer parking lamps
  • Intermittent or inoperative vehicle or trailer turn-signal lamps
  • Intermittent or inoperative vehicle or trailer stop lamps

How to Fix

Check the VIN for NHTSA recall 25V-893. Until the remedy is completed, Hyundai recommends parking outside and away from structures. When parts are available, a Hyundai dealer will replace the trailer wiring harness at no charge; the replacement control module has improved sealing to prevent water intrusion.

On the 2022-2024 Hyundai Tucson, tucson Hybrid and Plug-In Hybrid models repeatedly drain their small 12V lithium starter battery, leaving the vehicle unable to power up. The 12V battery is far smaller (around 19 Ah) than the lead-acid AGM used on the gas model, and persistent standby loads (Bluelink cellular connection, module wake cycles) plus a DC-DC converter that will not top off the 12V when the high-voltage pack is low can flatten it in as little as a day or two of sitting. Owners report using the dash-mounted 12V reset button repeatedly. A related BMS software service campaign addresses a 12V over-voltage warning.

Common Symptoms

  • Dead 12V battery / vehicle will not power on
  • Repeated need to press the 12V reset button
  • Battery drains after the car sits 1-2 days
  • Bluelink / remote features unresponsive
  • 12V battery over-voltage warning message

How to Fix

Use the interior 12V reset button to recover a temporary start; if it will not hold, jump from the underhood positive terminal and a chassis ground, then drive 30+ minutes to recharge. Apply the Battery Management System update under Hyundai Service Campaign 9B4 (DTC P1BB20 12V battery over-voltage). For vehicles parked for extended periods, drive at least 10 miles / 1 hour a few times a month or use a 12V maintainer; persistent drain after the update warrants a parasitic-draw test and 12V battery replacement under warranty.

Typical repair cost:$0 - $350

On the 2016-2025 Hyundai Tucson, the panoramic sunroof glass on the Tucson can crack or shatter spontaneously without impact. The issue has been reported across multiple model years and has generated significant NHTSA complaints. Thermal stress from temperature differentials and body flex during driving are suspected contributing factors. The large glass panel size makes it more susceptible to stress fractures originating from the bonded edges.

This issue also affects: Hyundai Veloster, Kia Sportage

Common Symptoms

  • Loud pop or cracking sound from roof
  • Spider-web cracks in sunroof glass
  • Glass shattered while parked
  • Water leak from cracked sunroof
  • Glass fragments falling into cabin

How to Fix

Replace the panoramic sunroof glass at the dealer. Hyundai has covered some replacements under goodwill warranty due to the volume of complaints. Document the damage with photos immediately and file an NHTSA complaint to support any warranty claim. Some owners opt to have a protective film applied after replacement, though this does not guarantee prevention.

Typical repair cost:$800 - $1,800

On the 2022-2024 Hyundai Tucson 2.5L Smartstream G2.5 GDI, the naturally-aspirated 2.5L Smartstream G2.5 GDI engine (distinct from the older Theta II 2.0/2.4) suffers from fuel dilution of the engine oil and, in some units, sticking oil-control rings that drive excessive oil consumption. Raw injected fuel washes past the rings into the crankcase, thinning the oil and, where rings stick, owners report burning roughly a quart per ~1,000 miles. Hyundai responded by increasing the factory oil fill capacity, lengthening the oil-level sensor range, and shortening the recommended oil-change interval.

Common Symptoms

  • Oil level dropping between changes (low-oil light)
  • Fuel/gasoline smell on the dipstick
  • Oil level reading above full (dilution)
  • Rising oil level with thin/diluted oil
  • Tapping or knock if oil starves under consumption

How to Fix

Perform a documented dealer oil-consumption test if usage exceeds about a quart per 1,000-1,200 miles to qualify for warranty repair (often updated piston/oil-control rings or a short block). Shorten oil changes to roughly 6,000 miles (some markets dropped from 15K to 7.5K), use the correct 0W-20/0W-30 full synthetic per the latest spec, and check for an oily fuel smell at the dipstick indicating dilution. Avoid extended idling and very short trips that worsen dilution; install any applicable engine/ECM updates.

Typical repair cost:$0 - $6,000
