I bought this car for my 18 year old son based on Mercedes reputation for safety and longevity, only to discover that Mercedes has a widely acknowledged issue with rotted sub-frames -- it's a serious safety issue and recalled in other countries. My son was was driving on the highway and the tire exploded. He was so close to being killed because the car went out of control. After getting it towed to my mechanic, he advised me that alignment adjusters were stuck, the subframe was rotted, the lower control arm subframe mounts were broken from the subframe and they were hitting the gas tank. Luckily, the tire only exploded as oppose to the entire vehicle bursting in flames. There were no warning lights or messages, only the feeling that the tires needed to be aligned. We bought new tires and were told an alignment was done from Town Fair Tires, which was untrue. My son's life was in immediate danger. Shame on Mercedes for not recalling this subframe. This is the first of many avenues I am taking to have this rectified and hopefully prevent a tragedy
