Almost in an accident as the airmatic suspension failed. Car suddenly lowered while driving. Changed air shocked, failed again after 2 years. This car has only less 93000 miles. All mechanics across the board know this is the problem mercedes has refused to take care.
When gas tank is full, I can smell gas from the drivers passenger side. When the gas tank is 3/4th tank, the smell disappeared. After research online there might be a problem in the rubber seal in the tank. It is a fire issue.
An unknown warning light was illuminated. Mercedes benz of walnut creek ([address], walnut creek, [ZIP], [phone]) was contacted by phone. The vehicle was not taken to be diagnosed nor repaired. The manufacturer was made aware of the failure and a case was filed.
The vechile has a very strong smell of fuel tbat I may believe is building up as it leaks in the undercarriage of the car
