2021 HYUNDAI Kona

About 2 weeks ago I tried to start my car and the dash board starting flickering and glitch. Roadside assistance said all I needed was a battery. I got a battery and everything seemed fine until today. My car is starting to do the same thing. When I looked up recalls my VIN doesnt match for a recall I think my car should be under. The Battery Charge Sysytem is failing I believe. I have videos.

The piston went through the top of my engine with my entire family in the car. We managed to get to a mechanic. And bring it to the dealership. We are very lucky to be alive.

The piston oil ring recall. I have had a mechanic determine I am having the exact same problem as the recalls but my VIN is not covered. Please update the recall so my repairs can be covered.

The contact owns a 2021 Hyundai Kona. The contact stated that while driving at slow speeds in stop-and-go traffic, the vehicle inadvertently lost motive power. The contact was able to restart the vehicle but almost immediately lost motive power. No warning lights were illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with the piston oil rings, resulting in damage to the engine. The contact was informed that the engine needed to be replaced. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 21V301000 (Engine); but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 96,000.

The HVAC drainage system in my 2021 Hyundai Kona failed due to a clogged AC drain line, which led to water leaking into the cabin and mold growth. The dealer reported the drain was blocked by a spiderweb and that moisture had collected under the driver and passenger carpets. They unclogged the line, but did not inspect beneath the carpet or inside the HVAC system. Soon after, I experienced musty odors, asthma flare-ups, and headaches while driving. At-home mold tests under the passenger seat and footwell came back positive. White mold was also visibly growing under the carpet. A similar issue occurred in my fiancé’s Hyundai Elantra, also purchased from the same dealer. His AC drain was clogged and mold tested positive in the cabin, though his car had no smell. Our vehicles are stored in different environments, which rules out external environmental causes and points to a broader design flaw. There are Hyundai forums online confirming this same issue is not isolated to us. Even if spiderwebs were involved, a single web should not disable a critical drainage function and cause health risks. HVAC systems should be designed to resist common environmental factors like debris or insects. I am a cancer survivor (diagnosed in 2024) and must avoid environmental toxins like mold. Despite repeated outreach to Hyundai and the dealer, I was told no inspection or remediation would be provided beyond detailing, which is not sufficient for mold. Component that failed: AC evaporator drain tube Confirmed by dealer: Yes Manufacturer inspection: No – Hyundai declined to investigate Safety concern: Yes – mold has triggered respiratory symptoms and makes the vehicle unsafe for passengers
