After breaking hard the vehicle started to pull left and the rear felt like it had locked up. I took it immediately to my local mechanic who diagnosed a prematurely rotted out subframe. I am in the process of having MB review and quote for the repair.

I had my 2010 Mercedes GLK in for B service today (Jan. 3, 2023), and the repair team inspected the vehicle and informed me that I have a RUST HOLE approximately 1" x 2" in size located adjacent to an attachment point for the wheels in the REAR SUBFRAME. If it breaks, it could cause the vehicle to become difficult to control. Additionally, they informed me that the BRAKE LINES are also RUSTING/WEAKENING. If the brakes fail while driving it could cause loss of control of the vehicle. Since these are hidden parts that I typically can't see, I had no warning that there was anything wrong until I had it in for routine maintenance. I have the invoice for the oil change, with a notation from the repair team regarding these parts. The vehicle is available for inspection should it be necessary.

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.

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"

My Mercedes GLK350 2010 (90K miles) has the same issue as mentioned in https://media.mbusa.com/releases/mercedes-benz-usa-announces-voluntary-stop-drive-recall-campaign-for-certain-model-year-2006-2012-ml-gl-and-r-class-vehicles but not included in the list of vehicles being recalled. This vehicle was taken to 'Ray Catena of Freehold, NJ' for checking and they identified the same issue - brake lines are corroded and leaking and brake pedal goes to floor and not effective at stopping (soft brake pedal). So I have exactly the same symptoms as mentioned in the recall notice for ML-, GL- and R-Class vehicles produced for the 2006-2012 model but my 2010 GLK is not included - hence requesting that GLK 350 to be included in the recall and this brake issue fixed by Mercedes Benz.

Acceleration/brake issue. On 09/0517 I pulled into my parking lot apartment complex and upon pulling into my parking spot, I attempted to back my 2010 Mercedes 2010 Glk350 to align my car. I put the vehicle in reverse, but suddenly the vehicle accelerated backwards and crashed into a parked vehicle. I attempted to apply the brakes, but the vehicle did not stop. Before the accident occurred on my dashboard it displayed "check brake pads". I purchase this car on 08/16/17 and was informed that the vehicle has (2) safety recalls for 'takata" airbags. This unintended acceleration in my 2010 Mercedes-Benz Glk350 is alarming and concerning.
