NHTSA complaint #11746027

Owner complaint summary

I am reporting a safety defect in my 2019 Mazda CX‑5 involving the heated seats and airbag system. The vehicle was bought certified pre‑owned with a warranty up to 100,000 miles included in the sale. Around March, at about 82,000 miles, the heated seats began causing electrical problems, and I was told this fault could affect the airbag system and that the airbags might not deploy in a crash. I have taken the car to a Mazda dealer four times and the issue has not been fixed; the dealer disconnected the heated seats and now claims they are “aftermarket,” even though they were on the car when I bought it and were never disclosed as aftermarket. I am now at about 87,000 miles, still within the warranty, and facing a large repair bill while Mazda corporate and the dealers refuse to correct this safety‑related defect under warranty. I am asking NHTSA to record this complaint and consider investigating similar issues with Mazda heated seats and possible airbag non‑deployment.
