2 Brake Sensor problem

Failure Date: 09/10/2014

I'm lucky to be alive! I purchased this car in 2005 and ever since I purchased my 2003 merc. Benz E320, it's been a crazy ride! here's a list of different issues that happened to me over the course of me owning this vehicle, which unfortunately I still do. I was driving with my little girl in tow and my brakes went out on me several times, my battery dies constantly, I had an issue when after I pumped gas you could smell fuel both inside my car & outside of my car, I literally one time had fuel pouring from the back of my car that ended on my garage floor. (thank god I don't smoke!) my suspension is constantly rattling, I have water that leaks on my feet when I drive occasionally and sometimes I have heat in the winter and sometimes I don't. I always have a check engine light on and as soon as I fix one, another one comes on. I currently had issues with code po134, po135 and had the O2 sensor changed, then my check engine light came back on and now I have codes po171 & po174 that I have no idea how to get fixed because it could be a number of issues. My battery drains when my electric seats are plugged in and so I have to have them unplugged to save my battery. Did I mention my back tire blew out on interstate 95 and I almost lost control of my car. It's devastating to pay the amount of money you do for this particular model, it's pretty on the outside and is a mess under the hood! is it normal when you have the ac on for it to sound like an airplane ready for take off? I'm tired of investing all kinds of money into this car, I just can't take it anymore! I can't even pass my va. State emissions test because of all these error codes (check engine light and malfunctions) and the state doesn't even find my car worthy of being on the roads.
