The alternator needed to be replaced just before the warranty expired. Unfortunately, the dealer said it was the air-mass sensor and wanted $900 to replace it.
I knew better, but they refused to fix the problem under warranty. They said the K&N air filter was the cause of the problem (water ingested and causing a short circuit). Since it was a non-factory item, I voided my warranty and they would not honor it.
Aside from the regular maintenance that ALL cars must receive, that was it.
This car is my first new car. I expected that over time, the car would become less reliable, less impressive to look at, less interesting to drive, or the performance would diminish. No such thing.
I am very satisfied with its performance and looks. My next car will have to perform and look substantially better - I'm talking about a Corvette or BMW to pull that off.
Fuel economy is great when you take into consideration its performance.
Barring any serious problems, I will keep indefinitely.
