The frequency with which air suspension struts collapsed was staggering.
The "service measures" pertaining to this defect are self explanatory.
Our warranty and paid repair records are the greatest proof of an abnormal failure rate. The fact that Mercedes Benz even introduced a "REPAIR KIT" and asked dealers not to replace struts in pairs shows how heavy the repair cost was to the company and customer and that it was becoming an issue with customers whose cars were just out of the two year warranty.
The examples of new car struts collapsing were also common and we have had multiple collapses in our own cars too.
However most shockingly we ourselves had a suspension strut on a CLS350 collapse instantaneously in a moving car on a three year old car which had already had one strut replaced when it was brand new. Now it has come to our attention that this is not a isolated incident and it continues across all models.
Mercedes Benz refuses to give data of failure rates.
