This vehicle, with 115,000 miles has been discovered to have had the brackets in the subframe for BOTH rear lateral arms rust through and are broken causing a $5,000 repair estimate. The mechanic who found this (42 years as a mechanic) said he has never seen anything like it. This is a car where I had to replace the transmission at 49,000 miles and the control unit at 62,000 miles (over $13,000 in repairs). I saw through AI search that this problem has been reported many times but has not prompted an investigation. This issue should NEVER happen and is a MAJOR SAFETY threat.

Subject: Safety Concern – Mercedes-Benz E350 4MATIC (2011) Subframe and Brake Line Rust Dear [Mercedes-Benz Customer Care / NHTSA], I am writing to report a serious safety concern regarding my 2011 Mercedes-Benz E350 4MATIC. Recently, I brought my vehicle in for recall service, and during the inspection, it was discovered that: The rear subframe is broken due to rust. The brake lines are extremely rusted, and I was advised that I could lose braking control if they are not replaced immediately. The estimated repair cost exceeds $4,000. I have been a long-time owner of Mercedes-Benz vehicles and part of the Mercedes-Benz family. However, I am now deeply concerned about the safety of myself, my family, and others on the road due to this severe corrosion issue, which I believe may be a widespread defect. I respectfully request that Mercedes-Benz investigate this issue and provide assistance, as the failure of these critical components poses a serious safety hazard. Thank you for your attention to this urgent matter. Sincerely, [XXX] [Phone: [XXX] ] [Email: [XXX] ] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Both headrests have now exploded in this car. I see there have been class actions lawsuits filed but Mercedes got these dismissed. There is a cheap plastic piece that holds the headrest in place which just explodes without any impact or accident. "The Mercedes class action lawsuit was filed by four plaintiffs who claim the NECK-PRO active headrests are defective because the activate head restraints allegedly deploy without crash impacts." The car was parked in each of the incidents. One hit my passenger in the head. The driver side headrest exploded today when I moved the seat. I called Mercedes but was just sent on a wild goose chase.

Is 223 complaints a lot? They were filed between 2011 and 2026, roughly 15 a year, which is more than the typical model in this dataset. We do not have sales figures for this model, so treat this as a rough volume, not a rate per car on the road. Popular, high-volume models naturally collect more complaints over time.

How does it compare with other years? The 2011 has 223 complaints on file, more than the 2010 (183) and more than the 2012 (217). Of the 7 model years of the Mercedes-Benz E350 we cover, the 2014 has the most (278). Older model years have had longer to collect complaints.
