Last Wednesday Morning June 06, 2023 I started vehicle up to move it closer to my apartment. Once I shifted into "Drive", immediately the engine revved up and vehicle accelerated in high rate of speed across the parking lot, I was applying the brakes, but they were not stopping the vehicle, it then slammed into wooded area and crashed head first into creek beyond the wooded area. I was dazed and bleeding from cut beneath my nose, I climbed out of vehicle and back up the incline the vehicle crashed downward into. Baltimore County Police responded and I explained to Officer what had happened. He advised me to contact my Insurance Carrier and wrote the Incident Report #. During the time while awaiting my vehicle's retrieval from the wooded area, I then photographed and video recorded the damages once retrieved. The air bags did not deploy when the vehicle crashed yet the complete front grill and hood of the vehicle was smashed in, front tire blown.

I noticed a strong gas smell after a full tank of gas with my Mercedes Benz GL450 after I received it back from the Mercedes Benz dealer to replace the driver side fuel sending unit to fix the broken fuel gauge. The strong gas odor was non-existent before the repair. Initially, I thought it was just a residual smell due to the repair but after a week when I filled again, the gas smell was still there. The smell is so bad especially in the morning when I get inside the garage. The smell is evident on the rear passenger side close to the gas tank. On January 11, 2016, I brought back the vehicle to the same Mercedes Benz dealer with a quarter of a tank to investigate the problem. After a couple of days, the service advisor told me that the technician/mechanic did the inspection and diagnosis but did not find anything wrong. I was asked if I overfill when I put gas and I said no. If Mercedes Benz could not find out what is wrong to an obvious problem, I don't know what's going on with the vehicle. As I have said before, this problem was non-existent before they dropped the tank to fix the fuel sending unit. I find it wrong that I have to shoulder the burden of worries and uncertainty to a safety problem that Mercedes Benz could not accurately diagnose. At this time, I do not really have a peace of mind safety wise whenever I drive this vehicle with my family.
