Driver side window did not roll smoothly. Squeaked but was only fixed after taking the car a dealer a third time. Sputtering/rattling sound seems to be coming from the engine when the car is idle or upon cold start. Sound gets progressively louder. Dealer claims that no sounds were heard. Car also hesitates when responding to acceleration. In researching for answers, I found that the driver's side airbag has a recall. I was in disbelief when I found that no efforts were made in contacting me about an airbag recall! I feel utterly disappointed. I'd come from a "Honda" family and decided to give Toyota a try. I have learnt my lesson now that buying a brand new Toyota means having to check up on recalls and problems.
