2014 Mercedes-benz CLS-Class Complaints

After the Mercedes dealer replaced the corroded rear sub frame under the 20 year extended warranty, my brake line failed so I took it back & found out that the brake lines were corroded. I paid nothing for the subframe since it was under the warranty but I ended up paying $4114 to replace the corroded brake lines. The dealer should have checked for corrosion while the subframe was out of the car, especially since this is a known issue. The parts were only $380 and $3800+ was labor. My brakes completely failed while driving on Christmas Eve. I took the car to the dealership on 12/26/25 and they told me that the car was unsafe to drive & I had to leave it. This should be covered by Mercedes under the rest subframe warranty since from what I’ve read, is a related issue. This was extremely dangerous. I was scheduled to travel back to NY, almost 300 miles from VA, where I got the car fixed. The dealership did not do their due diligence when the rear subframe was replaced so they had to drop...

I just had 2 tires replaced and on the way home I hit a pothole both front air shocks failed. I filed a claim and the insurance company won’t pay out either. Normal wear and tear does not make both air shocks failed.

the car started showing a low coolant message around 2017 about twice a year. I felt it was too often the message would come up. I would too off coolant each time to address it without seeing any leaks ever under the car. then 2018 thru 2019 the message would appear about 3 or 4.times per year. had it checked by Mercedes service and they advised nothing was leaking from the car and found no codes indicating urgency in repair to address. my car started failing to turnover after cranking and in July 2021 it failed to turnover at all ever again. took it to the factory sego r dealer and they examined the car for repair from 7/2021 to 12/2021 when they gave it back to me. after getting me to authorize $8,000 in repair cost to get it to turnover, and must needless repair, they advised it needs a new engine. it don't take $8,000 in repair to tell someone their cats needs a new engine. So that was unfortunate. furthermore the nhtsa issued a memo stating the coolant leaks into the engine oil...

have a 2014 cls-550 with extensive subframe rust. It is currently sitting at the dealership for $3,158 in repairs for a vehicle that is less than 10 years old. There needs to be a recall on the subframe for the c, cls, e, and like models. This is not the Mercedes’-Benz quality I expected. After extensive research, members all over the globe are experiencing the same issue. This isn’t user error. It’s manufacturer error. You need to make this right with your customers. Period. I have attached photos of my subframe. I’m severely disappointed with having to perform major maintenance on a vehicle with only 82k miles. This needs to be a recall. I cannot stress this enough. Stand by your product. You’re more than welcome to contact me. My vehicle will be in the shop for over a week and no loaner vehicle is available for use. The car is currently at Mercedes Benz of South Mississippi. I have owned multiple Mercedes’ products from c class, clk class, and two cls550s. This is what I sent to Mer...
