2022 Hyundai Sonata Reliability Report

Fuel injector trouble shows up here as well. The engine jerks violently, loses power or shuts off at highway speed and sometimes will not restart until after a tow. Several owners have had injectors replaced more than once under warranty, only for the jerking and poor fuel economy to come back. A second group reports overheating warnings under acceleration, fans running on high after shutdown, coolant loss with no visible leak and heavy white exhaust smoke. Dealers often cannot find a cause. Isolated reports mention knocking shifts and the engine stopping while driving.

These reports are mixed. The engine dies while driving, including in the middle of intersections during turns, and some cars shut off while idling when parked. Panoramic sunroofs shatter with no impact, in one case at highway speed, and warranty coverage was refused. Hybrid owners describe 12-volt charging failures that require the reset button, and one hybrid battery drained until the car shut off on the freeway. Other complaints cite the gear selector shifting on its own, high temperature readings blamed on the ITMS and a factory jack that tipped over during a tire change.

Unintended acceleration at low speed is the main concern. In two crash-related complaints, the car surges forward while pulling into a parking space and jumps the concrete stops, one at about 1250 miles. Another owner reports the engine revving and the car lunging at around 20 mph until automatic braking steps in. Other reports describe the opposite: hesitation or sudden speed loss with the pedal pressed. In one of those cases, a failed injector filled the cabin with fuel fumes. One owner linked hesitation to recall 22V746000, though that car was not included in the recall.

Most of these reports involve recall 25V796000, and the repair part is not yet available. Owners describe the engine revving on its own, jerking, stalling while driving and failing to restart. ABS, traction control and collision-avoidance warnings light up at the same time. Dealers replace valves, gaskets or spark plugs in the meantime, but the problem comes back. One car went back to the dealer repeatedly for the same fuel valve failure without a lasting repair.

Windshields crack without any impact, in one case twice within 4 months of ownership. That can also affect the safety equipment mounted to the glass. The other complaint describes washer fluid that will not spray on either side in freezing weather, so the windshield cannot be cleaned. That failure occurred at 400 miles. With only two complaints, these look like isolated problems rather than a widespread one.

Rear wheel bearings and hub assemblies deform early, and one report finds damage by 2400 miles. Symptoms include rear wheels that wander, shaking and a jumping feel while driving. The second complaint is crash-related. Under braking on a ramp, the car loses control and hits a curb, and the front wheel ends up loose from the suspension with a broken rotor and a hanging caliper. With only two complaints, no broad pattern is established.

Both complaints describe crashes, with 5 injuries in total. In one, the car does not stop in time for a stopped vehicle on the highway. In the other, the system applies full braking without ABS engaging, and the car slides into the vehicle ahead. The two failures point in opposite directions, too little braking in one case and braking that locks the wheels in the other. Both end in rear-end collisions.
