Two of the power windows failed first and then the power door locks. The master brake cylinder had to be replaced at 30K and the car has had perpetual suspension squeaks. At 60K a recurring oil leak occurred and despite close monitoring an engine bearing went out at 63K requiring a rebuilt replacement engine. Minor annoying transmission leaks occur today.
The suspension is very soft and cornering is sometimes a concern.
Well, it is a luxury car, after all. It is supposed to have a soft suspension. You aren't meant to drive it hard into the corners. It's not a Camaro or Corvette and you shouldn't try to drive it like one.
As for the squeaks, if you are getting them from the front of the car, try this. At the tops of the shock towers are a pair of rubber caps, longish and rounded at both ends. Pry these off. You will see a nut and rubber bushing assembly under there. Sometimes you need to spray some silicone on the rubber bushing and the squeaking will go away. You may also have to adjust the tightness of the nut. The rubber bushing should not be squashed flat by the nut. If the rubber bushing shows signs of cracking or breaking apart, it is a good idea to replace it. I hope this helps resolve your noise issue.
