Five years of fuel
$6,250–$12,030U.S. average; Ohio $5,580–$10,750 at local prices; every version of this model year; fuel only, not other costs of owning it; 15,000 miles a year, at EIA fuel prices for the week of Oct 12, 2026
NHTSA's VIN data lists these trims for the 2023 Sonata. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 102 complaints with NHTSA about the 2023 Sonata. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 2 recall campaigns for the 2023 Sonata over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Hyundai Motor America (Hyundai) is recalling certain 2020-2023 Sonata vehicles. A damaged check valve can allow air to enter the fuel tank, causing it to expand and contact hot exhaust components, melting the tank.
Risk: A melted fuel tank can leak, increasing the risk of a fire.
Remedy: Dealers will inspect and replace the check valve. The fuel tank assembly will be inspected for damage and replaced if necessary. Additionally, dealers will inspect and update the engine control unit software. All repairs will be performed as necessary, free of charge. Owner notification letters were mailed beginning March 13, 2026. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 286. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on November 19, 2025.
Hyundai Motor America (Hyundai) is recalling certain 2023-2024 Palisade Tucson, 2023 Sonata, Elantra, and Kona vehicles. The electronic controller for the Idle Stop & Go oil pump assembly may contain damaged electrical components that can cause the pump controller to overheat.
Risk: An electric oil pump assembly that overheats increases the risk of a vehicle fire.
Remedy: Owners are advised to park outside and away from structures until the recall repair is complete. Dealers will inspect and replace the electric oil pump controller, as necessary, free of charge. Owner notification letters were mailed starting September 7, 2023. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 246.
