I got in touch with Mercedes-Benz dealership in Westminster, CO, when I started smelling gas in my car cabin. The lady I spoke with told me that she would look into the issue and see if there was a recall and get back with me. She never called me back. After 3 weeks, the smell was so bad, that I was gagging in my car and had to drive with the windows open. I called the dealership again and they told me there was a warranty extension, but not a recall. I took the car in, they fixed the leaking gas tank that issue as well as an oil gasket and rear brakes (I had to pay for those). When I came to pick up the car, it was outside, not inside, as normal. In addition, the service rep was on a call with someone, and did not talk with me at all about the repairs. I got it to the car and it still smelled. I thought that the smell might dissipate over a few days. After several weeks, the smell did not go away, and seemed worse. I called them up and took the car back in. The service rep told me that the gas had leaked into the underlayment of the car and was actually deteriorating the car. He also told me to not "smoke in that car." However, Mercedes-Benz is refusing to repair the damage caused by the leaking gas. Not only is there a danger of explosion (hence the don't smoke), but also the inhalation on the gas fumes. I am livid, especially since I know they've replaced back seats for others. Is this because I am female?

I have a huge issue with MB. I own a 2006 CLS 500. This was my dream car. I wanted this car so bad but when I bought it, it gave me nothing but problems. More than twice my brakes went completely out, I could not stop or slow my vehicle down, red light flashed on my dashboard saying "stop reduce braking power". Do you know how scary that is to be driving on the freeway 65-70MPH & have a car cut you off & you can't Stop or Slow down because your brakes completely shut down shut off. There was another couple times I was driving at 45-55 mph on the street and I'm coming up on a red light and I can't STOP my car at all, the brakes lock up. I feel so lucky me or my family riding in my car were not injured.

Twice MB had to fix the RECALL SBC (Sensotronic Brake Control) on my car. CERTAIN VEHICLES, THE SENSOTRONIC BRAKE CONTROL (SBC) SYSTEM MAY PREMATURELY SHIFT TO THE HYDRAULIC BACK-UP FUNCTION MODE, DUE TO DETERIORATION OF THE WIRING HARNESS CONNECTION, OR DUE TO PREMATURE FAILURE OF THE HYDRAULIC PUMP. Twice they had to fix this problem.

I don't feel safe in this car at all. But the icing on this cake is once I got my car out of the shop I go to Costco & fill up my gas tank, come out from shopping and underneath the drivers side back tire Gas is leaking . Me & my family get in the car & it smells so bad of gas, which isn't good for a toddler to breath nor anyone to breath in for that matter. So I take it right back to the dealership & they diagnosed the problem Crack in my gas tank.

So since I'm catching on to all these car reviews online I do my research and come to find out that I'm not the only one with this or these problems on my 2006 CLS 500. Mind you MB said the gas tank leak & replacement would cost me 3,000$ to fix. So I'm doing my research and there is No Recall, just complaint after complaint about this gas tank leak. MB insists if I don't fill up my gas tank all the way it won't leak, I couldn't afford 3,000$ for a problem I knew MB was responsible for. So I've been driving around for one year & a half with a cracked gas tank, Dec 2015 I've exhausted all my options. / Now I can't register my car, the check engine light is on because of the crack in the gas tank. So I was recently doing more research and Finally MB extended the warranty & is going to cover the gas tank problem after letting me drive around with a cracked gas tank for one year and a half, doesn't sound very safe and reliable. Mercedes Benz slogan is "The Best or Nothing" I haven't gotten the best customer service. Roadside is picking my car up today 12-8-15 & MB of Scottsdale Az informed me since the gas tank is on back order 1-6 weeks and they can NOT give me a loaner car. But they are going to keep my car for 1-6 weeks untill the part comes in. And the service rep. informed me there is 13 people ahead of me waiting on gas tanks, so really who knows how long this will take. I called customer service they were of NO help, I called them a few more times explaining to them I will NOT have a car, how will I get to work?! They said borrow a friend or family member's car (I live in AZ with no family here unfortunately) But how could this be my problem. MB service rep also suggested I can still drive my car till the gas tank comes in. But I explained I've already used my extended registration from the MVD and I can't register my car without getting a smog and I won't pass smog because check engine light is on because of the Gas Tank Leak.... MB customer service won't do anything to help I asked them what would they suggest and they stay quiet !!!! I NEED ANSWERS !!

I can't afford to rent a car till when ?! 1-6weeks?! They can't even give me a damn date it will be down, everything is just up in the air & I'm sh*t out of luck.. I am NOT OK with the way I've been treated dealing with MB, I thought it was "The Best or Nothing". My problem still isn't solved MB roadside is on their way to pick up my car & I still have No transportation. But my car needs to be at the shop so they can order the part this is so ridiculous and absurd !!
