Today I was shopping in a store while my teenage son waited in the car for me. He came running in the store accompanied by a witness that was in the parking lot to tell me that something on my car exploded outside. The adult witness explained that the noise was so loud and so abrasive that they thought a bomb went off. It shook the entire car. Luckily nobody was hurt. What would have happened if this incident took place while I was driving the car? It has to have something to do with the air suspension.

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.
