Nothing at all.
I was looking for an equivalent replacement for my 1999 Saturn. This car is comparable to that.
So far the car has operated flawlessly. I like the 5-speed transmission. After having had automatic transmissions for the past 15+ years, I find it to be fun and gives the car more zip.
I think that the low resistance tires are a bit slick on wet roads and will probably switch to regular tires when it comes time to replace them.
After I put about 3000 miles on the car my highway mpg has settled in at about 40 mpg. My combined mileage hovers around 35 mpg.
This is the first car I've owned with the oil life indicator. It's nice to have and the oil lasts for 10,000 miles.
I have the 2008 version of your car. I agree, the tires are awful and I can't wait to replace them with ones that grip the road better. My average MPG over the life of the car is 29.3, with a near even mix of city and highway. The A/C is FLAWLESS and no mechanical problems out of the car in 15 months of ownership.
Don't listen to that oil life indicator. If your doing 10,000 miles oil changes, your car won't have even a chance at surviving.
Oil changes are cheap and they are the simplest way to prolong the life of your car. Change the oil every 3,000 miles, regardless of what anybody says. Some will say "Modern oil and engines will go 7,500 miles, 5,000 miles, etc. before needing to be changed." Don't listen, it's not worth it.
You must be in the 3k mile oil change club, which is outdated. If the oil life monitor goes off at 10k it's alright. GM has been tweaking it since the late 80's. I have one in my car, but it's the mid 90's version so the maximum interval according to it is 7.5k mile, which was probably based on quality of the oil at that time also.
I used to be a 3k oil change guy and ignored the OLM and I'm 21. But doing research and observing my oil still nice and brown, 3k seemed over the top, so I moved up to to 4k and now at least 5k.
This time I following the OLM for the first time and don't plan on changing it until it goes off as long as I don't disconnect the battery.
My dad moved away from 3k oil changes before I did. He won't change his oil until 7k. All of the car companies are moving toward longer oil change intervals, and GM has the most advanced oil monitoring system out of all of the companies. If you're super worried, use synthetic, it can withstand longer change intervals. 3k mile oil changes just waste resources and money.
