Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Every time I filled up the gas tank I would smell gas in the cabin and outside of the vehicle. It has been like this for two years. My car has very low mileage and it drives fine. I keep forgetting to tell the dealership the issues when I bring it in for maintenance. There is definitely an issues with the gas tank. It is getting worst as time goes by.

Every time I filled up on gas I would smell gas inside the cabin. I then proceeded to investigate into why I was smelling gas. I looked between the tire and the fender on the car on the driver side and noticed that there was a wet spot on top of the plastic under cover guard. At that point I took out the back seat and opened the access panel on the driver side and it was at that point I noticed fuel leaking. I then opened the passenger side and noticed the same thing, fuel leaking. Now that I know why I was smelling fuel I replaced the seals on both sides hoping that was going to fix the problem. I then went to the gas station filled up again to see if replacing the gaskets did the job. When I got home I opened both panels and noticed that I was still leaking fuel. As I looked hard at the pumps, sensor and leveler I noticed that the plastic electrical connecters that were molded to the top of the lids was no good and seeping out fuel. At that point I replaced both sides. I spent roughly around $550. I know it I had the dealer do it, it would have been double that. For a vehicle only being 5 years old it should not have these kind of problem with it. I am glad that I have mechanic skills to do things like this.

I filled up my gas tank and immediately could smell a strong gas odor on the drivers side rear area inside the cabin(the gas filler nozzle is located on the passenger side). I had to take it to the dealer on 2 occasions until it was repaired, my fear is this will be recurring.

Car will not go over 20 miles after stopping. I have to pull over put the car in park and restart. The car will run fine for awhile and a day or so later, the problem returns. This is extremely unsafe when your in traffic. I'm so afraid I'm going to get hit from behind trying to get off the road. I have been to 3 mechanics and told they cannot fix the problem due the theft deterrent on the car. I have an appointment at Mercedes on Friday and have been told it will be approx. $2000 to replace the plate in the transmission. Something needs to be done.

  • 52,000 miles
After filling the fuel tank, a very strong odor of raw gasoline coming from rear of car. The strongest smell coming from drivers side rear wheel well, no visible leaks detected. The smell is getting worse after each fill-up. Replaced the gas cap, no change in condition. Contacted the dealer from where car was purchased and inquired about similar complaints and fixes because another of my family has the same model with similar miles and has the very same problem, the dealer was unaware of any issues with this model. Because the car is out of warranty, will need to find a repair facility to solve and correct this issue before something catastrophic happens. Also found in research that this same issue has been found in other Mercedes models of the same model year.
