I am seeking guidance on the best path forward regarding a consumer warranty dispute for a leased 2024 Hyundai Ioniq 6.

I recently went through an grueling corporate escalation process with Hyundai Executive Customer Care to request a vehicle repurchase/lease termination due to persistent, severe mechanical defects. They called me today to officially deny the buyback, stating my only recourse is to continue taking the vehicle to dealerships for existing and new issues indefinitely.

Because the vehicle has 28,000 miles, it falls outside Lemon Law mileage limit (18,000 miles). Today, the vehicle's air conditioning completely failed and began emitting a loud mechanical failure noise.

I am driving a vehicle that I do not feel safe commuting to work in, and local dealerships have multi-week waitlists for diagnostics with zero loaner availability.

My Questions:

1. Given that I am past the state-specific Lemon Law mileage but well within the manufacturer's warranty, does this qualify as a strong Federal Magnuson-Moss Warranty Act (Breach of Warranty) case?
2. What are the practical steps for filing an official auto-dispute complaint with theMaryland Attorney General’s Consumer Protection Division? Does that usually move the needle with a stubborn manufacturer?

Crucial Case Context & Dealership Failures:

• Post-ICCU Failure & Replacement Noise: After the critical ICCU failed and was replaced, the vehicle began emitting an abnormal sound. I took it to the dealership twice; they brushed it off both times, claiming it wasn't concerning and that they couldn't replicate it. I captured video evidence because the sound specifically triggers in freezing temperatures. Now that the weather has warmed up, the dealership uses the excuse that it "cannot be replicated" to deny repairs.
• Post-Tire Replacement Vibration: Immediately after paying $1,200 out of pocket for a dealership-recommended tire replacement, the car developed a severe chassis vibration and noise above 60 MPH. I took it to the dealership twice for this issue:
  • Visit 1: The service department flat-out denied any issue existed.
  • Visit 2: A different technician finally confirmed the abnormal vibration. They claimed something in the front end was loose, "tightened it," and said it was fixed. It was not.
    •  When I messaged my dealership service advisor to ask how many more times I am expected to keep risking my safety and taking time off work for a persistent issue they cannot fix, they completely ghosted me and refused to respond.
