Hi,

In the next few days, i want to buy an EX. But the question I ask myself is this, turbo or not?
The turbo engine is reliable or not ? Does the waste gate is again a problem ?
What I'm looking for is the reliability.

Help me to make the best choice

Have you driven an SX back-to-back with an EX, to judge the turbo driving effects? This is my second turbocharged car, and I appreciate the power benefits, especially when driving at higher altitudes and in hilly terrain. The gas mileage in city driving will be more noticeable between turbo and non-turbo (probably 2-4 mpg), while highway mileage differences will probably be closer.

From a reliability aspect, a non-turbo will always be more reliable, but this one seems to be well-designed. The waste gate issues are quite resolvable under warranty if they arise.

If I had to do it again, I'd buy another SX.

I have a 2011 EX-Turbo (11,200 mile) and have had 0 problems. Just oil changes. The turbo was the only way I could get my wife out of a Hemi V-8 and into a smaller car.

I disagree with this statement. Modern 6-speed automatics work very well with the new generation of small turbos that develop maximum torque at low engine speeds. Between the nearly seamless transmission shifts and quick turbo spool-up, I always have torque when I need it, but the auto shift logic is also working better than a manual could to maximize gas mileage. That was true with my previous Audi DSG/2.0T and also with this Kia version. I rented an Optima LX in LA a few months ago and thought its auto transmission was much better than several (non-turbo) Sonatas I've rented.

BTW, the paddle shifters on an SX are a benefit IMHO - I use them to hold a gear on steep descents every day, but the auto-up and down-shifts do a very good job for everything else. All auto Optimas have the manual shift override at the lever, its just not quite as handy as the paddles.

This statement is out of left field. Its akin to saying, unless you're getting a manual, don't get a more powerful engine. It doesn't matter if you're talking an engine with more displacement, forced induction, or higher efficiency.

I currently own two turbo vehicles, one with an auto and one with a stick. I've also owned a turbo auto as well as a SC'd auto prior. I have plenty of good experience with forced induction automatics.
