5/5 Overall
NHTSA 5-Star Safety Rating
Complaints about the 2023 Sonata cluster most heavily around the fuel and propulsion system, with engine issues close behind. Owners of both the standard and hybrid versions report problems, though the symptoms differ by powertrain. On the turbocharged 2.5L models, owners frequently describe engine misfires, rough running, and stalling, in several cases the car loses the ability to shift into drive or reverse and has to be towed. Overheating complaints also appear, with owners reporting coolant loss and dashboard warnings. On the hybrid side, a recurring pattern involves the 12-volt battery draining completely, leaving owners unable to unlock the doors or open the trunk after the car has sat for an extended period. The powertrain category adds a smaller cluster of complaints, mostly from hybrid owners describing unexpected or unintended vehicle movement at low speeds while maneuvering in parking situations.

By System
The 2023 Hyundai Sonata has two recalls, both carrying fire risk: a fuel tank that can melt and leak after contacting hot exhaust components, and an electric oil pump controller that can overheat.
On the fuel system side, a damaged check valve can allow air into the fuel tank, causing it to expand until it contacts hot exhaust components nearby, melting the tank and creating a fuel leak that raises the risk of fire. The second concern involves the controller for the idle stop-start oil pump assembly, where damaged electrical components inside the controller can cause it to overheat, also posing a fire risk.
