Tires, Brakes, Oxygen Sensor Issues
 Tires were shot at 30,000 miles. Odd size makes replacement expensive.Rear brake pads shot at 30,000 miles (grinding heard on LR rotor). Lots of life left on the front pads, so what's up with that? Biggest disappointment was at 30,000 miles and 3.5 years both oxygen sensors on right exhaust went out at the same time. Bank 1 Sensor 1 and Bank 1 Sensor 2 to be exact.$700 repair.I like the car but the reliability is coming into question for us.
