After 4 months of ownership my wife noticed a whistle upon acceleration. I was told by the dealership that it is air passing over a hole in the throttle body. Throttle body replaced and problem persists. Contacted GM customer service and they told me it is not a mechanical defect and that "if it's not broke, don't fix it". My dealership stated they would keep me up to date on possible recalls related to this issue but after two months of phone calls they no longer call. This whistle is simply not acceptable for a $26,000 vehicle and GM wonders why customers are choosing foreign vehicles with better build quality. Interior plastic looks and feels cheap. I would not buy another one.
Love the sporting styling, strong engine and RDS. Very reliable vehicle. Lots of interior room for my family and a big trunk.
Interior has been improved on 2006 models. Perhaps enough owners will recognize the whistle problem and GM will order a recall.
