NHTSA Complaint #11649884 — 2025 MAZDA MX-5

my driver-side seatbelt buckle has been jamming since about one month after purchase. When I brought the issue to the dealership, they were able to temporarily fix it using an air compressor, citing that the buckle was full of "small debris". Upon further inquiry, I was told the debris consisted of "air particles and dust" and was advised not to leave the door open or drive with the top down. Given that this is a convertible, such a recommendation is unreasonable. It is unacceptable for a seatbelt buckle, one of the most critical safety components of a vehicle, to malfunction under normal usage conditions, especially in a brand-new car. This is available for inspection upon request. This malfunction prevents me at times from fully engaging my seat belt.
