There was a gas smell that would seep into the driving cabin from the engine. It was intermittent however when it did occur, the smell was strong enough to cause light headedness to the occupants of the vehicle. I took the car to my personal mechanic who told me that this was a common issue with these cars; however, Mercedes had not issued a recall. I my mechanic fix the issue since they had already diagnosed the problem. I did some research and discovered that there is class action law suit regarding this same issue. (Please see link below:). I am respectfully requesting NHTSA conduct an investigation into this matter as this is definitely a safety hazard as the gas smell could impair the driver to the point of not being able to drive the vehicle safely.
