Fuel Injector Failure
A defective batch of fuel injectors can fail without warning, causing rough idling, misfires, hesitation during acceleration, and difficulty starting. The issue has affected a large number of 2022 Tucson 2.5L engines and prompted multiple TSB revisions.
Hyundai released TSB 25-FL-001H providing a 4-injector replacement kit. Dealers will replace all four fuel injectors free of charge under warranty. Contact your dealer and reference the TSB.
Est. Cost: $0 under warranty; $800 - $1,400 out of warrantyDCT Transmission Hesitation and Loss of Power
Vehicles equipped with the 8-speed dual-clutch transmission (8DCT) may experience jerking, shuddering from a stop, delayed acceleration, and in severe cases complete loss of drive power. The transmission oil pump can malfunction, causing the vehicle to enter fail-safe mode before disengaging the clutches entirely.
Hyundai issued recall 22V-794 for the DCT oil pump malfunction. Dealers will inspect and replace the transmission as necessary and update the TCU software. Two additional TSBs released August 2023 address an improved clutch spring and updated shift logic.
Est. Cost: Covered under recallICU Software Causing Inoperative Lights
The software installed in the Integrated Central Control Unit (ICU) may be incompatible with the vehicle, resulting in headlights and/or taillights that fail to turn on. This creates a serious safety hazard, especially during nighttime or low-visibility driving.
Hyundai issued a recall to update the ICU software. Dealers will reprogram the ICU free of charge. Contact your dealer to verify your VIN is covered.
Est. Cost: Covered under recallRoof Molding Detachment
The roof molding on certain 2022 Tucson vehicles may loosen and detach while driving, posing a road hazard to following vehicles. Owners report hearing wind noise or noticing the trim peeling away at highway speeds.
Hyundai issued recall 22V-820 covering 2022 Tucson and 2022-2023 Santa Cruz. Dealers will inspect and resecure or replace the roof molding free of charge.

The infotainment touchscreen may freeze, go black, or become unresponsive during use. Apple CarPlay and Android Auto connections drop intermittently. Navigation may lag or display incorrect position data. Some owners also report Bluetooth audio cutting out randomly.
Hyundai has released multiple over-the-air and dealer-applied software updates to address stability issues. Visit the dealer for the latest firmware. A hard reset (hold the power knob for 10+ seconds) can temporarily resolve freezes. In persistent cases the head unit may need replacement.
Est. Cost: $0 for software update; $800 - $1,500 for head unit replacement
