White smoke always comes out the tail pipe every time the car sits for a few hrs or over night evertime I turn it on, it's always a quick good smoke and then disappears but the car runs well. ..should I worry?

When I pull off from a complete stop and I press on the gas my car hesitates to pick up speed

Took to shop had headlight replaced cost $141. After pull out of drive noticed check engine soon light is on. Husband is livid. Please help....also passenger side heat doesn't work just blows cold are when heat is on.

I used to hear a squealing noise (like a belt going bad) but, that was when AC was still working. The noise completely stopped and coincidently so did the cold air.... Is this my compressor? I hope it's something else....

Front struts which one do I need? Toyota Electronic modulated suspension or regular one? Also is it necessary to replace coil spring?

I have the sludge build up that everyone is talking about. Is there any resolution through Lexus customer service. I took it to an outside garage and had it diagnosed. Used syn oil and had regular oil changes as required. Any help would be appreciated.
