“Mercedes issued a recall for Mercedes C class for the model year up to 2015 for rear subframe that is rusting with holes in it. The dealer tells me my car is not covered by Mercedes even though it is a 2015 model. They gave me an estimate for the repair of over $5000. They say the model changed mid 2015 and mine is a model that is not covered. This could cause a serious crash at high speed. I am not sure why that repair is not covered for my 2015 model & I would like Mercedes to honor the repair.”

NHTSA complaint #11733647, filed 2026-04

“Component/System Failure: The rear subframe on my 2015 Mercedes-Benz C300 failed due to severe corrosion/rusting. The subframe is available for inspection upon request. Safety Risk: This failure created a serious and immediate safety hazard. While driving at highway speeds, the structural integrity of the vehicle was compromised, I had to break and lost control of the vehicle and almost causing a crash. This also posed a danger to other drivers on the road. The condition was severe enough that I believe I narrowly avoided a major accident. …”

“The car suddenly glitched and locked itself—with my dog, my purse, my phone, everything—inside on an extremely hot day. There was no one around, and it was terrifying. I had opened the passenger door for my dog to climb in, and as I walked around to the driver’s side, the doors somehow locked on their own. Panic set in immediately. My dog, my phone, and my purse were all inside, and I had no way to call for help. We had just finished a walk, and then this happened out of nowhere. I had to run around searching for someone who could help. …”

“I am filing a formal safety complaint regarding my 2015 Mercedes-Benz C300 (W205), with approximately 65,000 miles. An authorized Mercedes-Benz dealership diagnosed severe corrosion and perforation of the rear subframe and declared the vehicle undrivable due to this condition. The estimated repair cost is $5,531.53. The rear subframe is a critical structural component supporting the rear suspension. Its deterioration may compromise vehicle stability and potentially result in loss of control. I am extremely concerned that such a serious structural failure has occurred at relatively low mileage. …”

“Rear subframe rotted, hole like perforation on the frame. The current extended warranty covers the C204, but my Mercedes C300 2015 has a C205 that is the same part number, but for some reason the warranty does not cover the C205, but has the same identical issues as the C204.”
