The 2013 Mazda MAZDA3 has 208 problems & defects reported by MAZDA3 owners. The worst complaints are lights, accessories - interior, and engine problems. The first gear blocks more often and the second goes in with a crunch. Other gears are fine. Here are my theories: * The transmission is a piece of crap to begin with and has a manufacturing defect. * There is insufficient fluid in the clutch hydraulics. * There is an air bubble in the clutch hydraulics. You can get yourself into a Mazda3i Touring with the 155-horsepower 2.0-liter Skyactiv for $18,700, though our 3i Grand Touring with the same engine carried a more weighty $22,050 bottom line. 2012-2013 Mazda3 Misfire Issue. Equipped with SkyActiv engines. The problem: Misfire conditions may be found throughout the engine. This could be due to carbon deposits forming around the intake These cars being direct injection have a very high pressure in the fuel rail. There's actually two fuel pumps. Main pump in the tank supplies a pressurizing pump under your hood. If one of these two pumps aren't supplying sufficient pressure you'll get low pressure fault from the sensors. Mazda recalled 2012 to 2018 diesel Mazda 3, Mazda 6 and CX-5 because of carbon deposits build-up. Skyactiv-Hybrid. The Skyactiv-Hybrid technology is an electric hybrid engine technology using Skyactiv-G engine with technology from Toyota's Hybrid Synergy Drive, originally licensed for use with the Sky engine for vehicles sold in 2013. Engine technology supplier Bosch says that direct injection can return a 15 percent gain in fuel economy while boosting low-end torque as much as 50 percent. Combining direct injection with other Skyactiv®-g gasoline. Conventional internal combustion engines only harness around 30 percent of the potential energy of fuel. So Mazda engineered a smarter engine. By pushing the limits of internal combustion, the SKYACTIV ®-G 2.0L and 2.5L gasoline engines deliver much greater fuel efficiency. With higher compression ratios than Potential Motor Mount Issues. I've got a 2010 Mazda 3 2.5 6 speed with 75k on it. About a year ago I started getting a squeaking noise from the engine bay, always under clutch engagement/disengagement, or other situations where the engine mounts are under stress. I've diagnosed and replaced engine mounts on other vehicles, and this seemed like 9 posts · Joined 2010. #8 · Mar 5, 2012. The Skyactiv engine has been designed to minimize fuel useage and several of these design characteristics would tend to make it noisier. In addition to the previously mentioned fuel component noises, the block, crankshaft, bearings, and valve train have been lightened and reworked to reduce friction eeDmC.
