What 2010 Mercedes-Benz S550 owners say
Suspension
My S550 when driving would suddenly give a malfunction signal. I took it to the dealer, service replaced the 2 front struts. Now the call will give a signal, red letters, "do not move car" and the entire strut system will stop working and the car body is virtually sitting atop the tires. This after replacing the 2 front struts! The dealership seems to be at a loss and I can't even get them to return my calls. I don't think it is a strut problem but a computer glitch. I don't think it was necessary to pay for the strut replacement. I would like my car fixed or a refund.

Vehicle garaged in storage for summer. Upon returning strong odor of gasoline was detected. Reluctantly drove to dealership and prognoses was determined that (fuel pump strainer) had malfunction thus soaking the entire rear passenger compartment and seat cushion. Upon investigation Mercedes has had a problem in other C -models and has extended warranties for 15 additional years for this same problem. This vehicle is a S- 550 model. Dealership has denied any responsibility. I think the vehicle is unsafe at ANY SPEED. Never should fuel enter the passenger compartment of any vehicle. Video on file at dealership.
