What 165 owners told NHTSA about the 2017 Mercedes-benz E-class Wagon

Very strong gas smell coming from car especially in cool weather temperatures. The smell disappears when the car runs for a while but it’s terrible on cold starts. High or low pressure fuel line is the cause of it. Smell would disappear before reaching shops for diagnosis. Many other owners of same exact model experiences this as well.

The vehicle is getting stuck in parking and can not shift out of park. The issue first happened at the dealership when looking into an auxillary battery issue which has since been resolved. After over 30 minutes of trying to resolved the dealer was able to get the vehicle off the lift and switch the gear back into drive. Since then two days later the batteries were replaced and the same issue happen again (stuck in park) and now I see a transmission light on as well. I am not sure if the dealership noticed this when they had the issue in the shop. There was a previous transmission recall on the vehicle, which Mercedes said was previously addressed. My concern is that this can happen while driving which would be an extreme safety risks to myself and others. I don't believe I had any gear shift repairs since I owned the vehicle and the recall for my specific VIN may have been missed or not fully addressed. As of now I am unable to operate the vehicle and would like a recall reissued to resolve the problem. Thank you in advance for your assistance.
