I bought this vehicle new and within weeks of purchase it began displaying a warning light relating to the suspension system. I have had suspension problems over and over again with this vehicle. I had it at the Mercedes service center four times in less than 2 months this summer--each time was due to a suspension problem. I called Mercedes USA to no avail. They would promise a remedy but fail to follow through. I will not purchase another Mercedes because, in my experience, the company does not stand behind defective products.
