Battery & Propulsion Reliability
Hybrid (HEV)
Battery & propulsion complaint analysis for the 2015-2019 Hyundai Sonata
That's roughly 5.5x the typical rate for hybrids in this dataset (median 7.1 per year). This generation has materially more battery & propulsion complaints than its peers. The comparison is not adjusted for sales volume.
What kind of battery complaint?
Among the 195 battery-related complaints, here's the type mix. These percentages describe what the complaints are about — not how reliable the vehicle is overall.
Hybrid system warnings, eCVT, motor-generator, hybrid transaxle.
Loss of power, drive unit, inverter, traction motor, DC-DC converter.
Propulsion battery defects, capacity loss, BMS faults, replacement claims.
Battery fires, smoke, thermal runaway. Includes any complaint with fire reported.
Charge port, cable, mobile connector, or session failures.
Low-voltage battery deaths, common on EVs and hybrids that use a 12V for accessories.
Battery & propulsion recalls (1)
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.

Source: classified from NHTSA complaint and recall data. "Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. Rates are absolute counts, not normalized per-VIN — high-volume models naturally produce more raw complaints than low-volume ones. Self-reported death and injury counts are capped per complaint to limit form abuse.
