I have noticed a recurring issue during the colder months where there is a strong gas smell inside the cabin, and I have also observed fuel dripping into the engine compartment. This issue seems to occur primarily in winter conditions. I was surprised to find that there has been no official recall or service bulletin addressing this concern, especially given the potential safety implications.

My car on has 80,000 miles and the camshaft position sprockets needs to be replaced. I went to a Mercedes dealer and this was the diagnostic. This causes the engine light to come on, hesitant engine, low acceleration while driving. The dealer said it will cost $8,000 to be replaced and still can go bad. There was a recall for this issue before. RecallCampaign2015100007

I was leaving a gas station after pumping gas, and as I began to turn onto the road my car failed to respond in any way. It would not accelerate or break, the wipers suddenly came on and the headlights and emergency lights began blinking off and on. I was 1/2 second from being t-boned in the driver-side door by an oncoming Ford F350. The Ford F350 driver lost control of their vehicle trying to swerve to avoid hitting my car and did a 360-degree turn in the middle of the road, almost being hit multiple times by other vehicles because the Ford F350 ended up in the lane of oncoming traffic. Only by the Grace of God no one was seriously injured or killed. The SC State Trooper coincidently witnessed the incident and said I should contact the NHTSA, to report what happened when I understood what would cause the car to become incapacitated mid-operation. My car would not turn off and NONE of the controls to anything in the car would work. It took the tow truck driver over 2 hours to figure out what fuse to pull to force the car to turn off before it could be towed. It was towed to the Mercedes dealership on Laurens Road, Greenville SC. 9 weeks later, last week, I got a call from the service tech, he explained to me the drain tubes in my sunroof were clogged, which caused water to flood the front seat floor subcompartments. He said so much water had flooded the subfloor that even 9 weeks later over 3 gallons of water were vacuumed out. The water had caused major damage to the electrical junction boxes in the subfloor and caused them to short out, incapacitating my car while driving. The tech explained there was no way I could have prevented the damage or even known the tubes were clogged, or the subfloor was becoming flooded. There are no maintenance requirements listed for the drain tubes that could have made me aware that the car could become incapacitated while in drive causing serious risk to myself and other drivers. This should be looked into ASAP.
