After driving on slight up or down hill with headlights on, I'm getting Headlight malfunction warning on my almost brand new (700 miles) Miata.

Taking my car in for now the 3rd time for the headlight error "Headlight System Malfunction. Have the vehicle inspected. The first 2 times it occurred around 3000 miles where they first tried a software and reset then it did it again so took it back and they swapped the left headlight which had failed. Then it was good for a few months until the issue came back recently around 7500 or so miles. Now it's doing it pretty consistently again and I suspect the right headlight has failed. Taking it in today to get checked out again. I'm surprised it's not a recall at this point as headlights are important and allow you to see at night. Seems to have the issue whenever the lights come on now so it's pretty consistent. I've checked forums and I am not the only 1. There are many ND3 owners with the same issues of failing headlights or in some cases other modules.

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.

Subject: Update – Campaign Warranty Claim Response Enhancements – Modules Not Repaired for Certain Campaigns Dear Mazda Dealer Colleagues, On October 28, 2026, a change was implemented in the warranty claim response screen to provide precise information for all campaigns requiring module programming or module replacement subject to the LECS system software checks. As previously announced, some claims were automatically rejected with the Edit code JN1 – One or More Modules Are Not Updated when submitting a campaign warranty claim. This response was based on the session file received from MDARS or MDARS II at the dealership and the VIN on the claim submitted. This change provides additional Related Information which enhances the edit code information. This information allows the dealer to correct the error without contacting Warranty or Hotline. Edit code JN1 now contains the actual module name and the software version that was collected from the car and what the minimum required software needed to be for the claim. Using this information, the technician can now identify the exact error or errors and correct the concern.
