I don't really agree with this. I mean, it's open to some interpretation. But if you look at technology sharing during the merger, it was all one direction. Mercedes engineers were notoroiusly resistant to share their cutting-edge work or be influenced by Chrysler. And what you saw was several outdated Mercedes platforms being reused on Chryslers: The outgoing E-Class platform reborn as the 300C, the outgoing C Class platform as the Crossfire.

Now it is true Mercedes suffered through a lot of QC problems during that era. But I've studied this and evidence points primarily to maintenance issues. Around that time, powertrains were refined, many models shedding superchargers for naturally aspirated engines, a move to pure synthetic oil was made in the more mass-market models, and to compete with TCO numbers from BMW and Audi, Mercedes set 15k mile oil change intervals. They pulled them back in 07/08, released the stunningly reliable W204 C-Class, and things have been on the mend.
