2020 Hyundai Sonata

A damaged check valve can allow air to enter the fuel tank, causing it to expand and contact hot exhaust components, melting the tank. This creates a serious fire risk. Owners may notice a fuel smell, fuel tank deformation, or a check engine light related to the evaporative emissions system.

Hyundai issued a recall covering 2020-2023 Sonata vehicles. Dealers will replace the check valve and inspect the fuel tank, replacing it if necessary, free of charge. Owner notification letters were mailed January 2026.

Vehicles with the 8-speed dual-clutch transmission may experience a transmission oil pump malfunction that impairs the fail-safe limited-mobility drive mode, potentially resulting in a complete loss of drive power while driving. Symptoms include sudden loss of acceleration, warning lights, and the vehicle coasting to a stop.

Hyundai issued recall 22V-794 for 2021-2022 Sonata DCT models. Dealers will inspect and replace the transmission as necessary and update the TCU software free of charge.

On Sonata models equipped with the 2.5L turbocharged engine, fuel may leak at the pipe connection between the high-pressure fuel pump and fuel rail. A fuel leak near hot engine components significantly increases the risk of an engine compartment fire.

Hyundai issued a recall for 2021-2022 Sonata 2.5T models. Dealers will inspect and tighten or replace the fuel pipe as necessary, free of charge.

Some owners report the engine hesitating or stalling during acceleration, particularly when pulling away from a stop or merging onto highways. The issue is often linked to transmission software calibration and throttle mapping. Cold weather may exacerbate the symptoms.

Hyundai has released ECU and TCU software updates to reduce hesitation when accelerating from a stop and improve shift quality. Dealers will apply the latest calibration update. Multiple TSBs address this concern.

Owners report rattling noises from the exhaust system, particularly from the catalytic converter heat shield. Some vehicles also experience premature catalytic converter failure, triggering check engine lights with catalyst efficiency codes (P0420). The exhaust heat recovery system can also develop leaks.

Have the dealer inspect the exhaust system for loose heat shields and tighten or replace them. For catalytic converter issues, the repair is covered under the federal emissions warranty (8 years/80,000 miles). Hyundai has TSBs addressing exhaust heat recovery system concerns.
