Benz E500 2004 (54K miles) safety issue1: Nov 2008(36K miles), the car used to lose power and shut down while driving with all the lights blinking on the dash board. But I was able to break ansdstop. Sometimes it started back on and sometimes it did not.dealer replaced the crankshaft sensor and the sender unit. Had to pay the bill of $600 plus towing. They did not inspect other safety issues like the sbc pump or let me know about the 10 year warranty. Neither did they tell me if sbc pump failure or its malfunction has any impact on other parts of the car. Safety issue 2: Jan 6th 2015.(refer to complaint #10676289)sbc pump failed during a long road trip and thinking it was just brake pads, could have been fatal. Dealer/mb refused any assistance in repairs. Cost us $2200. When the dealer refused to look at the sbc pump before the warranty expired and they know it is going to fail, customer is in a very uncomfortable position with safety aspect, huge repair costs involved and possible impact on other parts and situations. They designed a warranty on this programmable unit that is programmed to lend certain cycles or service. Mercedes Benz has turned this major defect into a money making opportunity lately. They are installing reman units with a high repair cost of $2000-3000. Sometimes, more than the worth of the car. Regulators should revisit the case and have them provide life time warranty on this major flaw and maybe more. When there were two recalls just a year after it was bought, how can they get away with a 10 year warranty and a huge repair cost. Since they have more lawyers than any common man, only regulators can help the citizens and protect their interests and safety.

I filled up my car & noticed a gas smell I was on my way to atlanta for work I had to inhale strong gas fumes for most of my travel. When I got there I took my car to a shop & they discovered my gas tank had a leak and gas was leaking near back seat they gave a me an estimate of about 2500 to fix I was told that this had been a known issue for Mercedes but no recall yet which I don't understand. This is very dangerous not only the inhalation of the fumes & gas leaking in a car with electrical wiring & parts that get extremely hot. I don't understand why there hasn't been a recall to fix this since Mercedes are aware that the car was manufactured properly. Why should we have to pay to repair poor manufactured products that put our lives in danger.

After refueling, car had strong odor of fuel leaking. Fills garage with fumes. Worried that Pilot light will ignite fumes. Also, fuel gauge sticks on 1/2 tank even when tank is empty.
