- LATCHES/LOCKS/LINKAGESNHTSA 21V619000Aug 6, 2021
Hyundai Motor America (Hyundai) is recalling certain 2017-2018 Sonata, 2016-2018 Sonata Hybrid, 2018-2020 Accent, and 2016-2017 Azera vehicles. The trunk latch may become damaged, preventing the opening of the trunk from the inside. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 401, "Internal Trunk Release."
Consequence: A person inside the trunk compartment may become trapped, increasing their risk of injury.
Remedy
Dealers will replace the trunk latch base, free of charge. Owner notification letters were mailed December 4, 2021. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 208.
- HYBRID PROPULSION SYSTEMNHTSA 18V166000Mar 12, 2018
Hyundai Motor America (Hyundai) is recalling certain 2016-2018 Hyundai Sonata Plug-In Hybrid vehicles. These vehicles are equipped with a Voltage Protection Device (VPD), designed to protect the high voltage battery module, that may activate inadvertently.
Consequence: If the VPD activates while the vehicle is being operated in Electric Vehicle (EV) mode, there may be a loss of power, increasing the risk of a crash.
Remedy
Hyundai will notify owners, and dealers will remove the VPD switch and install a new Battery Management System (BMS) that contains an Overvoltage Protection Device (OPD). The recall is expected to begin May 2018. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 175.

Reliability verdict for the 2018 Hyundai Sonata
With a 64/100 score against a 75/100 segment average, the 2018 Hyundai Sonata lands below the class norm for reliability. The gap is meaningful enough to place it in a mixed-to-moderate band rather than near-average. Recall activity is limited, which suggests fewer formal corrective campaigns than some peers, but it does not offset the overall score deficit.
Complaint patterns are not evenly spread. Reports cluster most heavily around the engine, with electrical system concerns forming a clear secondary tier. The remaining issues—unknown/other, powertrain, and exterior lighting—add breadth, but they sit behind the dominant engine and electrical themes. As a fourth-year model in its generation, the data still points to elevated owner-reported friction.
Overall risk level is moderate to elevated relative to the segment.
