When using the A/C, cold air comes out of the driver's side vents, but hot air come out of the passenger side (inconsistent with temperature settings). This problem happened relatively early, but I was too busy to take it in under warranty. Now I just live with it and keep those vents closed in the summer, since the expense to fix it would be too high for the benefit gained. This is one of many quality control problems with this car, with the biggest being the engine.
