Filed Jul 17, 2020 · Fuel system · 120,000 miles · CA

When my windows are down and im driving you can smell gasoline very strongly in the car. Even worse in the back seat area. Especially if my gas tank is filled. Im constantly getting a warning to check the gas cap and the gas light goes off flashing then my check engine light will go on.

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.

Crankshaft position sensor - the engine shuts down without any warning, sometimes while driving at speed. I tried to restart it several times, but to not avail. It may restart after the engine has cooled off (after 20-30 minutes) but the problem repeats itself when the engine has been running and warm again. The check engine light came on and a malfunction message: battery protection - conventional functions temporarily unavailable displays. Once at the repair shop, the mechanic knew what the problem may possibly be even before testing for the check engine code. He said he's seen this problem for quite some time. The problem code did come up with a bad crankshaft position sensor as he predicted. I researched this problem on several mercedes benz owners? Forum web sites and discovered numerous entries from owners with this exact same problem, affecting several mercedes model years. I called mercedes benz and asked why a recall was not issued for this problem and what they were doing to compensate owners for the repair cost or at least a notification of this problem. I did not receive a favorable outcome but was told by the customer service representative that she would escalate the issue internally so that they would be aware of the issue. I believe that mercedes benz has known about this problem for years and it continues to affect many owners. Having the engine shut down with no warning is very dangerous especially if the car is being driven at speed on the highway.

While traveling in the far left lane on a four lane highway the engine on the car stops in addition to the check engine light coming on. I could not move to the left shoulder because it was an additional lane for high occupancy vehicles which was also barricaded. I immediately placed on my flashers and commenced to change lanes to get off of the highway. Where this also occurred was where an on-ramp connects which added on another obstacle in an attempt to get off of the highway. It was very fortunate and lucky that no accident occurred as in the dallas area during rush hour it is very hard to just change to one lane with a running car let alone changing lanes 3 times plus dealing with merging traffic from an on-ramp with a car that is not running. After having the car towed to the dealer, the crank shaft sensor was found to be the defect. It is clearly a safety flaw by the vehicle manufacturer to completely stop an engine when a defect occurs on a sensor. In this condition the vehicle should only turn on the check engine light instead of turning the car off to place the operator into a potential deadly situation.

My 2003 mercedes e320 engine stalled momentarily as I sped up to enter I-95 near fredericksburg, va. I eased up on the gas and it restarted with no apparent immediate after effects. Fortunately, there was no traffic close behind me, or there might have been a collision. There were no warning lights showing on the dashboard before or after the stalling. I continued south on I-95 with no further problems until I exited at ashland, va. At the interchange with us1, when I stopped at the traffic light, the engine stalled out and would not restart, blocking traffic. A policeman arrived and called for a tow. Again there were no apparent trouble lights. The car was carried to the richmond va dealer, which replaced the air mass sensor. This corrected the problem. I reported this problem to mercedes customer care in nj. I emphasized the seriousness of having the engine stall out, but they were not planning to perform any new fix. They said it was "operating as designed", making reference to a "limp home" feature that stalls the engine and warns the driver to get off the road. I looked in the car's manual, and the term "limp home" appears only once concerning the engine. However, there is no description of how this works or what the driver is supposed to do. In my car, the engine did not "limp", but ran at full power after the stall and restart. In my opinion, a sensor failure should not disable the engine, and any serious problem should be warned through a blinking check engine light. Mercedes needs to remedy these problems through a recall. At the very least, owners of these cars should be warned about the potential problem, and how to deal with it if it occurs.
