My wife's 2010 limited convertible passenger window is not dropping when door handle is opened. It is also acting crazy going up and down when traveling over rough roads. We have owned the car for less than a year and only has about 23,000 miles. The only issue we had when purchasing from the dealer was the ignition key wouldn't work well and get stuck. They replaced the key cylinder the day after we purchased the car. Hope this not a sign of things to come!!!
