2022 Hyundai Tucson Reliability Report

Horns stop working, sometimes losing one tone first, and some cars need them replaced three or more times. Audio cuts out across all speakers, which also silences safety chimes. A service bulletin exists, but external amplifiers have been back-ordered. Other cars lose several systems at once, including turn signals, side cameras, driver aids, and the dash display, until restarted. Rear brake lights and turn signals failing is tied to an open recall that had no remedy yet. Complaints also include a parked-car fire and crashes blamed on sudden acceleration, with 2 injuries.

Panoramic sunroof glass shatters at highway speed with a loud bang and no apparent impact. Two parked cars caught fire, and one fire damaged about a third of a house. Several crashes describe sudden surges while parking or creeping forward with auto hold on. Automatic emergency braking also brought one car to a full stop on a freeway with nothing ahead. The fuel door actuator can fail, and opening it means taking apart a trunk panel. Other reports describe limp mode that caps speed at 25 mph and repeat injector failures.

Two main problems show up here. Automatic emergency braking slams on at highway speed with no traffic ahead, sometimes several times in one drive. The brake pedal can also go soft or stop responding, and several low-speed crashes are blamed on brakes that did not engage. A few owners describe brake system warnings with the car creeping at stops, fixed by replacing the IEB module and the brake pedal module. A master cylinder failure and a garage fire also appear, along with 3 crashes and 2 injuries.

Airbags fail to deploy in serious collisions, including head-on, side, and high-speed rear impacts. Several of these cars were totaled. Nine of the 11 complaints involve crashes, and occupants report concussions, head injuries, and bruising. One crash with an elk ended in an engine fire with no airbag deployment. Outside of crashes, an airbag warning light can point to a failed control unit. One owner was quoted $2100 for the repair and told that the airbags and seatbelt locking would not work while the light was on.

Phantom braking dominates. The car brakes hard with nothing ahead on highways, off-ramps, parking lots, and even in reverse, which risks rear-end collisions. Owners link it to vehicles slowing in adjacent lanes, low sun throwing the car's own shadow ahead, and a blocked radar warning on sunny highway trips that also shuts off cruise control. Turning the feature off does not always stick, because it reactivates on its own. Dealers often cannot reproduce the problem, and one reportedly said no fix was available. One crash complaint says the system failed to brake at all.

Acceleration problems go both ways. Some cars hesitate badly from a stop or will not go faster than about 40 mph until the pedal is floored, often in the first few thousand miles. Others surge unexpectedly while parking or reversing, and two crashes resulted, one with an injury. Cruise control has jumped to a much higher set speed on its own. Speed sign recognition has slowed cars to 25 mph in faster zones. Dealers frequently do not diagnose or repair these problems.

Without warning, the wheel locks up or turns very heavy, usually mid-turn, while the dash fills with driver-assist warnings. Some owners had to force the wheel to get off the road, and one car was towed. Dealers log fault codes but often cannot find the cause. One repair replaced a multi-fuse and the steering wheel wiring. Another report describes brakes and power steering failing together at very low mileage. Cruise control buttons on the wheel can stop responding or come loose.
