I have a 2006 Sonata and I am experiencing multiple problems with it, but I'm trying to get advice before I take it in to the dealership.

It has 98.5K miles.

First problem: My heater is having issues. The driver left vent blows hot air, the driver right vent blows warm air, and the two passenger vents blow cold air. This is vey frustrating because the two cold vents keep the whole car cold. If I close the two vents, the driver side vents blow colder. All my fluid are topped off.

Second problem: My car squeaks, a lot, and very loudly. I know this is probably due to suspension problems, but I don't know exactly what & I don't want to get ripped off. It's noisy when I go over bumps or into dips.

Third problem: When I go to leave my house in the morning and put my car in reverse, it makes a loud bang/thunk noise. It does it again as I begin to roll back, but then nothing. It doesn't do it any other time I back out and it has just recently started doing this, about two weeks now.

Any and all advice would be greatly appreciated. I know I need to take it in, but I don't want to get the run-around or fed a bunch of bull. I definitely want to get educated before I do so.

 

1. Does you car have dual zone HVAC?

2. The car is old with a lot of miles. Suspension parts do wear out and start to make noises

3. Probable the cold weather. When was the transmission last serviced? Has the fluid even been changed?
