Bought a 2023 Mazda CX 30 Preferred new, until recently at 4000 miles have a loud clunking sound when driving over rough roads and over bumps and became more pronounce when the mileage hit 4000 miles on the odometer. The clunking sound seems to be coming from the front end of the car. The car is still under warranty and will be bringing it to the dealer to have it diagnosed and repair if needed. I will give update after seeing a mechanic from the dealer.
