My car’s left side rear subframe is cracked due to corrosion. I started hearing a weird noise a week ago, and my car suddenly veered to the left side when I pressed the brake. I almost crashed my car because the car moved to the left of the yellow line on the road. I searched about this issue on google and found that many c-class owners (w204 generation) are experiencing the same issue due to the design flaws/defects by mercedes-benz. Now I have to pay up to $10,000 for the repair that is due to a defective part. In other countries like the uk and south korea, this issue is covered by mercedes-benz, but in the united states, it is not covered. The repair is done at owner’s expense. I fear driving now because my car steers to the left when I press the brake. The rear subframe must be recalled since this issue is now common to all c-class models produced in 2008-2014, and if car accidents occur, many people can be killed. I almost crashed my car due to my rotten subframe. Please help.
I noticed my 2013 mb C350 was making strange noises and vibrations. I could feel the car steering in a different direction when I let go of the wheel. I took it to my service dealer and was told the subframe was severely rusted which included the suspension, struts, and even brake line. I was told the car was dangerous to drive and had to keep it at the shop for 45 days while waiting for the parts to come in. Apparently this is a "common" issue with this generation of c-class. There should be nothing common or normal about a rotting subframe after only 8 years of use. This a manufacturer's defect and the manufacturer needs to be held responsible for using inferior parts for cost cutting measures. I had to pay several thousands of dollars for an issue that shouldn't be an issue for 20+ years.
The rear subframe is corroded, the rear subframe is a structural part of the car that mercedes refuses to cover under warranty or issue a recall for even though it is issued under recall in canada.
1. The (rh) rear suspension forward link attach point on the rear suspension cross-member (mercedes-benz p/n: 204-350-01-41), separated from the sub frame due to internal corrosion of the suspension cross-member. Part available for inspection. 2. When part failed, the rh rear wheel alignment was no-longer fixed; some loss of vehicle steering control was experienced, especially during braking and also turning. 3. Numerous reports of similar episodes of this failure are reported in owners' and maintainers' forums. The dealer service department was familiar with this suspension cross-member part failure. 5. This vehicle passed a maryland state safety inspection performed by the seller of the vehicle 6 months and 5000 mi prior to the part failure. 6. Part failed with no warning, during normal driving on secondary roads.
Rear subframe rusted through on both sides and broke while driving about a year ago. Nearly lost control of the car. There was 55,000 miles on the car at the time. Also, I have another vehicle same w204 car series 120,000 miles on this car. VIN [xxx]. Last week the rear subframe broke on that car while driving. Came very close to having serious wreck on i77. Mercedes replaced and paid for the first vehicles subframe. I paid for the labor. They are giving me 30% off the repair of the one now in the dealers shop. I have been told by a mercedes service manager that this is a prevalent problem around the country and that mercedes knows they have a problem with the subframe on this model. I have researched this on the web and found many others with the same problem. This is a very serious safety issue. I would not be surprised if someone has died from this part failure. Please investigate this for a recall. It will save some lives. Redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
Front right spring broke. This is the 2nd spring that has broken in less than a year. This time the broken spring was rubbing against moving parts and smoking at only 5 mph. If this happened at higher speeds, or on a curve, I suspect it could be dangerous. There are numerous reports of mercedes springs breaking on vehicles with less than 50,000 miles. That would certainly indicate to me that either the design or springs are defective.
