Less than 1 yr after I purchased my vehicle, I began having problems with oil consumption. I took it to the dealer and they did oil consumption test and replaced crankcase breather valve and fron main seal & ecm update. High oil consumption continued, dealer stated that it was acceptable as long as it was 1200 or more per 1/4 qt of oil. I have complained several times and dealer says it is normal for the car. Now, I am past my warranty and the car is consuming 1/4 quart oil to 760 miles. After some research on internet found that many people are having issues with the oil consumption on this vehicle and the auto maker is not addressing the issue. Others had pistons and rings changed to resolve the issue. Currently, I am spending an extra $90 a month on oil. I have had many issues with this car and see that this model year is riddled with issues. I also had issues with fuel injectors after receiving notice that it was highly unlikely that my car would have such an issue and after 3 returns to the dealer they finally acknowledge that it was a fuel injection issue and replaced them.
