what is the problem The Mercedes vibrated when parked or while drived.

What is your question?

The car was parked and has no tune up for 2 years because of the gas system "recall" problem. It was shutting up on the road even when my tank was 3/4 and when full there was a smell of gas. I found out about the recall in February I brought the car to Mercedes and they fixed it. After the repair I noticed a noise, kind of rumbling, and i can feel a vibration in the wheel even when the car is parked. I don't drive the car normally I drive it in the neighborhood and parked it. Also the noise increase when the ac in on. The ac is not pumping full cold air in the front and give hot air in the back. When I put my hand in front of the vent I can barely feel the cold air. What problem am I dealing with?

What makes this problem better or worse?

It is worse when the ac is on

How long has your 2005 Mercedes-Benz E500 had this problem?

Notice in february. After Mercedes Benz fixed the recall gas system problem
