I've owned my car all of a month, had a coolant leak, then had to replace the spark plugs, and the manual trans fluid, and now the car wants more. Today on to lunch break, she popped the check engine light on, and my 2012, 1.4 Turbo, stayed on my mind all day at work. It ran well enough, and I got it home, scanned it, and found P0171 for lean fuel system. I found, using my scan tool's live data, that the long term fuel trim was running a +32%, so I popped the hood, and I can clearly hear a vacuum leak towards the back of the engine, around the intake manifold.

I'm still in powertrain warranty until the 23rd, and 101,000 or so miles, so I'm going to take it to the dealership and have them fix it. At this point, though. I've had an issue a week with this car, and on the assumption that the pattern will continue, I've hit this point where I want to tell the dealer I want them to buy it back. 1 month of ownership, and 2 warranty repairs, and having to do a tune up and manual transmission service is... Safe to say, cause to believe it'll be a money pit, and that's just not acceptable. My Saturn SC2 never caused me such trouble. Am I just having a serious run of bad luck, and it'll taper off? Or should I expect this to be an uphill battle?

Your problem is the PCV valve thats molded into the valve cover. But you need to have the dealer check for the orange check valve in the intake as well.

More than likely you'll be getting a valve cover and a completely new intake under warranty. Search PCV Intake Repair.. The tread was started by XTremeRevolution. If I find it I'll post it below. Make sure they check the intake, and don't just do the valve cover. The issue will come back

I am aware of the PCV issue, I'm actually fairly certain that's not my issue, because my engine isn't short on power, and I put my thumb over the port on the valve cover, and it didn't seem to lose that vacuum leak sound. That said, it's still extremely irritating, because I have only owned this car a month, and the intake manifold on this car was changed 30,000 miles ago, about a year ago.
