Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Infotainment system freezes and crashes The large infotainment system of the NX4 freezes regularly or restarts. Software updates from the dealer can help, but the problem is widespread. Symptoms: Screen freezes, navigation crashes, sat nav/radio no longer responds from 20,000 km | Low | |
| 48-volt system and start-stop faults The 48-volt electrical system in early Tucson NX4 examples generates fault messages without a stored diagnostic code. Start-stop switches off uncontrollably, starter responds with a delay. Symptoms: 48V system fault message, start-stop unresponsive, starter makes noise on restart from 30,000 km | Medium | |
| Condensation in headlights Tucson NX4 headlights show condensation moisture inside, which impairs visibility quality and can damage the LED units over time. Warranty replacement is generally straightforward. Symptoms: Misted headlights, water film visible on reflector, reduced light output from 20,000 km | Medium | |
| 48-volt system malfunctions The mild hybrid 48-volt network shows sporadic fault messages and causes start-stop system failure. Several owners report complete power shutdowns while driving and necessary control unit resets. Symptoms: 48-volt system fault message on display, start-stop system not working, spontaneous power interruption from 30,000 km | Medium |
