The general sentiment seems to be this is one of the most durable/reliable turbo engines on the market. There were some head casting issues affecting certain 2016-2020 models and leaking valve stem seals in 2021, but both of these issues are covered by Mazda TSB's.

But, I recently found two places, non-Mazda, that identify issues with the 2.0/2.5 Skyactive engines. Neither says how common these problems are. But, combined with some other factors (using a 2.5l 4 cyl to push around a 5,000 lb CX-90 being one of them) I'm wondering if all is so perfect in Mazda land.

2008年3月1日 · These engines would be shared by Ford, Mazda, and whoever else in the Ford family with the need for it. - Mazda did this and developed a 4-cylinder engine family in the following displacements: 1.8, 2.0, 2.3. Even though the Mazda3 1.6l is often referred to as a MZR, it's actually part of a smaller engine family (remember my rule #1).

Mazda should be ashame of themselves taking people money. I was told by the tech a Mazda that this is a common problem Mazda is having with the cx7's and that tells me that they are very much aware of it, but will not stand behind this issue. It is very sad. Mazda need to recall all of the cx7s and fix all of the problems they know exist.

2008年12月14日 · Actually I believe the Mazda 2.3 engine has been one of Ward's top ten engines for several years. Also the before mentioned problems are very minor and easily fixed.

Infortunately, the 2007 model year seems to be loaded with engine and turbo problems that occur prematurely and very early in the life of the car. Just take a look at all the message boards about the engine problems. Check out www.mcx7.com and www.mazda247.com #1) That is a good question. One would think that the CEL would light up with such a ...

We have a '97 mazda b4000 we have had problems with the butterfly valve getting dirty and needs cleaning periodically. Recently the engine stalls and sputters when changing gears similar to a dirty butterfly valve, but the valve is clean and the air filter is new. There was one vaccum hose that needed replacing, done.

2024年4月29日 · There are many turbos that are quite reliable, despite how many say Hyundai are shit, their turbos are least of the problems and many VWs with the EA888 engine has turbos and its usually other issues causing problems like water pump rather than the turbo giving out.

2023年5月4日 · The engine internals are significantly different to deal with this boost, including a different cylinder head, different pistons and rods, with a lower (10.5:1) compression ratio. The "Dynamic Pressure" trickery that Mazda installed in the exhaust manifold spools the turbo up quickly at low rpms by forcing exhaust gases through a smaller port ...
