2022 Hyundai Santa Fe Reliability Report

A melted under-hood fuse box and engine harness knock out the blower motor, leaving no airflow, often after a hot or melting smell. Dealers say they see this in multiple 2022 models. One fire report describes a parked car burning from under the driver-side dash near the fuse wiring. Horns keep failing. Some cars shut down completely while driving, which takes away park, the parking brake, and the hazard lights. Other complaints cover rear doors that stay locked, a blank dash screen, and a backup camera that stays dark.

Smart cruise control shuts off with "Check Forward Safety System" or radar-blocked warnings, sometimes with code C162078. In some cars the dealer replaced the front radar module. Other cars buck, shake, and lose speed on the highway because fuel injectors fail, and the injectors fail again after repair. Some reports describe revs climbing to 5,000 rpm without a shift, which owners tie to transmission recall 22V746000. Other reports describe slowing on its own from 67 mph and smart cruise dragging the brakes downhill until the rotors were ruined at 2,500 miles.

Fuel injectors on the 2.5L engine fail again and again. The car hesitates, jerks, shakes, and loses power, and some owners smell gas. Code P0302 is among the misfire codes reported. Bulletin TSB 25-FL-001H covers internal injector filter breakage and calls for replacing all four injectors, but parts were quoted up to three weeks on backorder, and some owners are on their third replacement. Hybrid owners report sudden loss of acceleration with a warning to stop driving. Other complaints describe a fuel range display that stays the same after filling up or reads wrong.

Automatic emergency braking engages for no reason, mostly at highway speed, with an "Emergency Braking" warning and a hard slowdown that nearly gets the car rear-ended. Some owners say it fires as cars pass in the next lane, and one says the car also swerved. Dealers often find no fault. The front radar also drops out, which disables cruise control. Two crash reports say the system failed to stop the car, one at 5 mph and one in 20-degree cold, which the dealer blamed on the weather.

Two crash reports describe brakes failing at low speed. In one, the pedal sank to the floor at a red light with no fluid loss. In the other, the car accelerated and braked on its own and hit a house, and the manufacturer blamed the driver. Rotors develop hot spots that make the car shake under braking. This starts around 7,000 miles, and dealers turn the rotors, but the shaking comes back by 16,000. Phantom emergency braking at 50 to 60 mph is also reported.

Two crash reports describe air bags that did not work as designed. In one, the front air bag did not deploy when the car was rear-ended at 55+ mph and pushed into another car, and the driver was hurt. In the other, the steering wheel bag barely deployed and threw sparks and smoke, and a door-side bag tore. Other complaints describe a passenger air bag off light that turns on when a short passenger uses a cushion, and an air bag sensor warning the dealer would not cover.

Rear collision sensors stop working with no warning message. One crash report describes backing into an object and damaging the liftgate, and the same car nearly hit another vehicle backing out of a driveway. The other complaint is about recall 24V879000, where the repair part was not yet available and the owner waited longer than they considered reasonable.
