2022 Hyundai Kona N

There would be a stumble when accelerating up to highway speeds at random times. During acceleration on a highway on August 30, 2025, that stumble became constant and the engine light came on. Exhaust sounds was no longer smooth and constant but rather a constant sputter. Greater vibration was felt in the car anytime the accelerator was depressed. Pulled off the highway and can visually see the motor vibrating significantly. When accelerating from a stop or crawling speed, it struggles to move and I can feel the resistance of the car not wanting to accelerate. Auto parts store scanned the code and it came back as a misfire in cylinder 3. Concerned about engine damage, being stranded, or causing an accident, the car was dropped it off at the Hyundai dealership. At that time (around 2pm) I was far from home and the service center was closed. On 9/5/2025 I was notified that the fuel injectors will need to be replaced and they are currently on order.

While driving after a recent car wash, my car entered limp mode, limiting the engine to 2000 RPM. Multiple warning lights for electrical, safety, and engine issues appeared on the dashboard, and the error code P211800 was displayed. Despite being inspected at the dealership, the issue couldn’t be reproduced, and the error code disappeared. This problem has occurred twice, but each time the dealership was unable to identify the cause since the error code was no longer present.

I bought a used from Route46Nissan. Horn wasn't working when I bought the car and battery was also dead which I had to pay out of pocket to replace. I realized that two tires have side bubbles and which is extremely unsafe which they sold the car like that with security issues. They sold me a warranty and they are not keeping their promises for the stuff that they need to fix

This bulletin provides information related to the navigation and head unit software changes introduced in the 2026 2nd Navigation Map and Software Update. The changes may vary depending on vehicle type, model, and navigation system. Refer to the 2026 2nd Navigation Map and Software Update Key Improvements and Additional Improvements tables in this TSB for a list of specific changes. The software can be downloaded via Navigation Updater (NAU) and updated by USB.

Some Hyundai vehicles may be equipped with a parking distance warning (PDW) sensor(s) that may trigger various DTCs and display warning messages on the instrument cluster, resulting in the PDW sensor(s) failing to detect nearby objects or triggering multiple false alarms. This condition may be a result of external damage to the PDW sensor membrane or sensor cover from rock chips or road debris, a collision, or previous vehicle repairs or modifications.

Some vehicles equipped with internal combustion engines may exhibit higher-than-expected engine oil consumption. This bulletin outlines the combustion chamber cleaning procedure for vehicles diagnosed with this condition. All internal combustion engines consume some engine oil during normal operation, depending on driving conditions and mileage, and this procedure should only be performed when deemed necessary based on inspection and diagnosis of the vehicle as outlined in TSB 26-EM-015H, Engine Oil Consumption – Inspection & Repair Guidelines, or the latest revision.

Certain vehicles equipped with internal combustion engines may exhibit higher-than-expected engine oil consumption. This bulletin provides the inspection and repair procedures for vehicles exhibiting this condition. All internal combustion engines consume engine oil as part of normal engine operation. Oil consumption rates may vary based on mileage, operating conditions, driving habits, and maintenance history. Hyundai recommends following the prescribed maintenance schedule and periodically checking the engine oil level using the dipstick to maintain proper engine oil level.

This bulletin provides information related to a Transmission Control Unit (TCU) software update for some vehicles equipped with an 8-speed wet dual clutch transmission (8WDCT). The software update revises the touch point learning variation, improving drivability and judder symptoms. Certain 8WDCTs (indicated by a new part number) received an updated clutch spring. The correct TCU software update must be matched with the correct corresponding 8WDCT hardware, otherwise, drivability concerns may occur. This service procedure should be performed prior to any 8WDCT replacements done for drivability/judder concerns.

Certain 2021-2023 model year Kona, 2021-2023 model year Kona Electric, and 2022-2023 model year Kona N vehicles may experience an inoperable horn that may be caused by foreign substances causing internal parts to oxidize. At Hyundai, we are committed to providing vehicles of outstanding quality and value. In an effort to meet this commitment, the warranty coverage for the horn assembly replacement has been extended to 10 years / 120,000 miles from the date of original retail delivery or date of first use (whichever occurs first) and is valid for original and subsequent owners.
