Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Many owners of late-model Mercedes-Benz cars equipped with 3.0l and 3.5l v6 engines (m272 or m273) have experienced performance problems that include poor idle, loss of power and a check engine light with a p2006 code (or sometimes other codes). The shafts will fail inside the manifold and bind, causing the lever to break and the caps shown to look like they are popping off the manifold.”
