What Are the Common Problems With the Kia Forte and Mazda 3?
Oil use and a dead battery lead the Mazda 3 reports. Owners add a quart every 1,500 to 4,000 miles, or face repeat no-starts that dealers cannot trace. Brake surge at low speed and steering that binds then releases are the crash-linked areas. The Forte's trouble is heavier. Transmissions skip gears or stick in sixth, engines fail without a warning light, and cars start with a USB cable. Its airbag area is the starkest: 22 of 29 complaints are crash-linked, and the Mazda 3 has no airbag area among its main problems.
