Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“No incident. Was driving and as I pulled into my driveway, heard bumping sound from car. Asked mercedes what it was, they said loose baffle in gas tank. Sounds like manufacturing defect. Checked online and found many others with same problem. It is a costly repair just outside of warranty period.”
