2010 Acura TL Questions

Does it need to be done

STARTED INITIALLY INTERMITTANT...NOW NO WORK AT ALL..NO LEAKS (DYE WAS USED) FULLY CHARGED. ALL SENSORS APPEAR TO BE WORKING...

I was sitting for about 3+ plus hrs in accessory mode in my car. I went to start the car and it wouldn't start. I turned everything off and waited for an hour and tried again. The car started but with hesitation. Once on i got multiple lights......check engine emission, check VSA system, Check Hill start, and Power steering. After a few minutes the power steering came back but the other didn't. I got codes P0306, P0300, P0302, and P0339. Can someone tell me whats going on and possible solution

XM says it is antenna. Acura says not likely.

When you first start the car the heat is fine at 69-70 degrees. After about 20-25 min. of run time the air is cool. Have to turn up the heat 5 or 6 degrees to get any heat. Does anybody know why?

My car is in for oil change at 41,000 miles. Dealer says valve adjustment is routine maintenance

I need to replace rear passenger side bumper reflector.

Right rear reflector on a 2010 acura tl

When I start the car and begin to accelerate, the engine (maybe) has a loud rattle noise like it is "trying" to work. Once it gets to third gear, the noise goes away. This only happens on a cold start, not when I am stopped at a traffic light or such. I have had it to two different Acura dealerships and have had $3K repairs done but the noise is still there. If I take it to other shops, nothing comes up on the diagnostic test. It sounds horrible and is embarrassing. This started at around 69K miles. PLEASE HELP! I do not want to be screwed out of more $$$ by Acura!
