On 10/5/22, my wife was driving her 2010 GLK 350 to work, suddenly she felt the break pedal was going deep inside easily and noticed break fluid light warning sign in dashboard. She was scared to drive and slowly drove car to Mercedes authorized technician. After diagnosis, MB technician said the issue in not just on break fluid leaks but the entire breaking system is failing due to rear subframe rust which holds the entire suspension and body. He said car is not safe to drive will cost $4K to $10k to repair. Called another dealer near by said the same as this is common issue with Mercedes due to snow the subframe rust during winter. It is ironic that even with frequent servicing with dealer they never found these rust issue early because rusting process started early on any metals. Went online to dig deeper on this issue and surprised this issue is widespread check https://mbworld.org/forums/c-class-w204/805501-rotted-rear-subframe-2.html#post8650716 Apparently Mercedes recalled all C class cars to replace subframe as they realized it is their design issue in Europe, UK and Canada. Here in USA dealers give excuses saying it due to winter snow it rust even though they did not catch such dangerous safety issue in the car. Imagine if how severe this break safety issue. Please take action on Mercedes Benz to address this safety issue US, specially it has been addressed in UK, EU, and Canada.

The cross beam-in the rear are completely rusted out as are the brake lines. I had this vehicle from brand new and there isn’t any rust except for there.This problem has happened in Canada and other countries. Mercedes’ Benz has recalled it there and not in the United States. I stope to a representative at Mercedes Benz and she said they were aware of the problem and said it would be the next recall. I’m afraid to drive this vehicle it’s unsafe

SERVICE BRAKES, ENGINE
I took my MB in for service to have alternator replaced. After it was finished service did a multipoint inspection on vehicle and keep in mind I have had my car in for service before and if there had been a multi inspection wouldn't this have been seen before now? This report includes Rear sub Frame rusted & broke, rear brake lines rusted, fault code for intake manifold flap malfuntion, actuator arms broke, engine misfire on cylinders 3-5. Recommended Services is to replace transmission mounts, left engine mount, right engine mount, rear sub frame, rear brake llines, intake manifold. diagnose misfires. All of this and I was never notified of any issues before now and its only been a year since my car was in before. I was also told I didn't need an oil change and my brakes were only making noise because of wear!? And due to the issue I was also told to be very careful when I do drive! Total cost for this is $11,996.85 So I feel that MB is liable for this as there has not been any recommendation s before now. I had $2,081. worth of work done February 5th 2019 and the underbody of vehicle was inspected so why was this not caught then?

UNKNOWN OR OTHER
My 2015GLK 350 shifts into an Automatic P (Parking) while driving under 6 miles per hour. When shutting the car off and immediately starting, the transmission automatically performs another Automatic P (and puts the car into Park) when driving under 6 miles an hour. This puts myself and other drivers at risk. The failure first appeared 60 days after purchase of this vehicle (first happened in August 2021). I took the car in to the independent repair shop in Long Island, NY in Nov 2021. I've had the car looked at and by an independent repair shop and they could not immediately identify the issue. No warnings lights or sounds went off before the automatic p (park) happened. The independent dealer did some research and referred me to an alert from 3/2015 *Topic number LI54.25-P-056472 Version 3 *Key in Electronic Ignition switch (EZS) is not recognized, automatic transmission shifts to Park before vehicle comes to a stop! Cause - An assembly issue I am wiling to get the car repaired, just wanted help with Good Will Assistance from Mercedes Benz, because he cause of this issue is assembly related and my VIN falls under the alert/assembly issue.

My mechanic reported that the subframe is corroded and that the vehicle is unsafe to drive. He told me that I cannot drive it at all. Apparently this is a very common problem in C class and Glk class Mercedes vehicles. I read that this problem is considered a recall issue in Germany and Canada, but not here in the US. My suv has 102,000 miles and is in good shape otherwise…. This is a very dangerous issue that Mercedes in not acknowledging as a recall.

The rear sub frame corrosion which caused the back tire of the driver side to fail off and lose control of the vehicle, which put myself and other drivers in harm because of lost of vehicle. The rear sub frame has corroded sooner than it's lifecycle. The dealership has confirmed the issue, inspected the part and has replaced. There were no warning lights that have gone off on the vehicle to notify of the issues. Driver hit a pot hole and the frame cracked due to premature corrosion.

Dealer reported to me that the brake lines are rusted. Dealer reported the lines are painted rather than coated as they were in the past. Vehicle is less than 10 years old so brake line rusting seems unusual.

FUEL/PROPULSION SYSTEM
Due to the same defect Mercedes issued a recall for on the 2011 GLK, the fuel and sender pumps cracked due to a product defect causing gasoline to leak out of the vehicle as well as into the vehicle. The leak is near the exhaust causing a high degree of risk for car fire. Online research reveals numerous 2010 GLK owners with the same issue at various points in the life of the vehicle.

My concern is the repeated failure of the front wheel speed sensors rendering the ABS system and Traction Control System inoperable. The Speed Sensors failed as follows: 1.) 2015 at 9,474 Miles 2.) 2020 at 26,293 Miles 3.) 2022 at 30,281 Miles The vehicle has extremely low miles for the repeated failures to have occurred. If you research various Mercedes Benz Blogs online, you will see a trend of repeated speed sensors failures in all models of Mercedes cars & Mercedes Vans.
