Battery & Propulsion Reliability
Battery Electric (BEV)
Battery & propulsion complaint analysis for the 2018-2023 Hyundai Kona
That's about 2.0x the typical rate for BEVs in this dataset (median 5.5 per year). Above peer average — but high-volume models naturally produce more raw complaints, so check the issue mix below before drawing conclusions.
What kind of battery complaint?
Among the 47 battery-related complaints, here's the type mix. These percentages describe what the complaints are about — not how reliable the vehicle is overall.
Propulsion battery defects, capacity loss, BMS faults, replacement claims.
Loss of power, drive unit, inverter, traction motor, DC-DC converter.
Low-voltage battery deaths, common on EVs and hybrids that use a 12V for accessories.
Battery fires, smoke, thermal runaway. Includes any complaint with fire reported.
Charge port, cable, mobile connector, or session failures.

Sample complaint excerpts
High-Voltage Battery
- [2019] There has been a battery recall on our Kona EV since March 2021. We were asked to keep the battery charged only to 80% to prevent problems. Hyundai is aware that we need a battery and we were contacted in late summer to set up an appointment to replace it. Every time we try to set something up they tell us that they don't have the battery or the proper parts. This is unacceptable. We have spoken w
- [2019] I was directed by Jennifer Kruger at the NHTSA to complete this form. My 2019 Hundai Kona EV is part of the EV battery recall. On August 27, 2021, my local dealer took my car while waiting for a replacement battery. I do have use of a rental vehicle. I've reached out to Hyundai Customer Service many times in an attempt to find out when my care will be fixed and returned to me. I've not been a
- [2019] Took my 2019 Hyundai Electric Kona into dealer on 7/30/21, re: Recall #200. They kept the car for 2 1/2 weeks, finally determining that the entire battery pack should be replaced. Five months later, I am still waiting. The maximum charge is at 80%, I have brought it in for all the other recalls. The dealership keeps telling me that they have some battery packs, but that those are for "other" custo
Electric Propulsion
- [2019] Component Failed: Electric transmission/drive unit failed twice before 150,000 miles. Still in vehicle, available for inspection. Safety Risk: Loss of propulsion while driving creates risk of being rear-ended or stranded in dangerous traffic conditions. Right now the car is not drivable Confirmed By: Problem confirmed by Hyundai dealership/service center on both failures. Inspection: Inspected
- [2020] While driving approximately 70 mph on I-10 in Louisiana late at night, my 2020 Hyundai Kona EV displayed a “Check EV System” warning while I was on the highway. There were no safe areas or emergency shoulders available to pull over, so I continued driving toward the nearest exit. Approximately 15 minutes after the warning appeared, as I attempted to exit the highway, the vehicle suddenly lost pow
- [2020] I am concerned about the safety of my car and have little faith that there are qualified mechanics who understand EVs and can properly service an EV car. Two times on April 9, 2024 (and on at least 4 other occasions in 2023) while drive at approximately 45 miles an hour on a RI State highway at a safe distance from any care in front of me, my vehicle went into the fail-safe mode while I was drivi
12V Auxiliary Battery
- [2020] 6/17/2024 12 volt battery was dead; EV was fully charged 6/16/2024 using Level 2 charger in my home garage. AAA charged the battery; I drove to Crossroads Hyundai Loveland, CO and asked to have the converter to the main battery checked; this was not done. Crossroads checked the battery via CADEX with "good battery charge" as result. No other diagnostic work was performed. 8/26/2024 12 volt battery
- [2020] We just had our 2020 Kona updated from the dealer with major software and recall updates. Since that point the car has been draining from the 12volt battery on it's own and killing the charging circuit for the battery. It has caused us to have to jump start the car and not be able to keep the 12 volt charged which runs all of the environmentals and car systems. Unless you have a jump pack with you
- [2022] The electrical system is not fulling shutting down after the vehicle is turned off and the 12 volt battery drains. This also caused the Instrument Panel to fail and made the car not safe to drive as we had no speedometer or odometer. The battery drain happened over and over again. The car is a lemon. This car has been at the dealer since December 30th, with no fix in sight.
Thermal Events
- [2019] The manufacturer has announced a safety recall (NHTSA Recall Number21V127000) due to the hazard of battery fire. It has been months since the recall was announced (and a year since battery fires were first reported) and the manufacturer has offered no remedy. Manufacturer has not provided timely communication or remedy to this safety problem, and we need help from NHTSA to get a safe solution
- [2021] The contact owns a 2021 Hyundai Kona Electric. The contact stated that while his wife disconnected the charger, the vehicle caught fire without warning. There were no reported injuries. The installation plug was melted. The vehicle was taken to the local dealer where it was diagnosed the connection wiring needed to be replaced. The vehicle was not repaired. An inspector was able to inspect the ve
Charging System
- [2022] The push door to the charging port locks and I am unble to open it. It will sometimes unlock if I push the unlock button several times. This is worrisome since I need access to the charging port to charge my batter. Not sure if there is a design flaw with the latch to the door.
- [2021] July of 2022, vehicle went in due to battery not charging. Vehicle kept at Temecula Hyundai repair until September 2022 for EV battery replacement. Upon return, EV battery still didn't change. September 2022 vehicle went back for repairs. Returned October 2022. Was told battery overheating sensor was faulty and was turned off. As a result the EV battery will not be able to charge beyond 90%. Was
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.
