There were two incidents, one when my daughter was driving and one when I was driving. We were on a highway going 65 mph and had to brake as we came upon traffic. The car fishtailed/swerved back and forth out of control several times until we could bring the car to a stop. I had to pull onto the shoulder so I didn-??t hit any of the cars near me. It was terrifying and I felt lucky that I didn-??t have a serious accident. When I got home, I took my car to my local mechanic who inspected the car and said my rear subframe was cracked and rusted out!! After doing some research and talking to the Mercedes dealership where I bought the car, this is a widespread problem with several different models over many years, but they have not issued a recall. Apparently the frames were not rustproofed properly so they are rusting/corroding from the inside out. These frames should last the lifetime of the vehicle with no issues!! There are thousands of people driving their cars out there with this problem and they have no idea that their cars are UNSAFE to drive!!! Someone is going to get killed if Mercedes does not issue a recall for this problem. They recently sent an internal memo to all of their sales and service managers in the US saying they will offer an extended offer on the rear subframes. This does NOT help because many people are unaware of the problem and haven-??t received notification that something could be terribly wrong. Mercedes has know about this problem for years and Canada and Europe issued recalls on the rear subframes 2 years ago!!! How can Mercedes USA allow their customers to continue to drive UNSAFE vehicles"!" A class action has been proposed for this problem because Mercedes has been so remiss in their responsibility in protecting their customers. Please please please bring this to light before someone gets injured or killed!!!!

The contact owns a 2011 Mercedes Benz Glk350. The contact stated that while driving approximately 55 mph, the brakes erroneously activated causing the vehicle speed to slow down. After stopping to inspect the vehicle smoke was present coming from both the driver and passenger side rear wheels. The vehicle was driven to the local dealer Mercedes Benz of sarasota located at 4754 clark rd, sarasota, fl 34233 who diagnosed that the ABS module was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was not notified of the failure. The failure mileage was 148,603.

We have a Mercedes Benz Glk350 2011. While neither of its brake warning (which includes warning for low brake fluid level) and "check brake pad wear" display messages is on, and there is no abnormal noise from the brakes, its brakes can still fail for a short time, while work most of the time. In two cases, while I was waiting at a red light, the brake failed and the car moved forward, then stopped before it hit the car in front of it. At first I thought maybe I didn't pressure the brake pedal hard enough. After an accident happened, I am sure it was the brake's problem. In one case, while I was backing the car down the not-too-deep driveway in my home in a sunny, dry day, the car kept moving even when I pressed the brake pedal. I was pretty sure I pressed the brake pedal because I was able to move the transmission from "R" to "P" position. Even when the transmission was in the "P" position and I pressed the brake pedal hard, the car still moved down the driveway just as if there were no brakes. I should emphasized I drove over one hundred of times on the same driveway, and when the brake worked, I could always stop the car on the driveway! to summarize, my Mercedes Benz Glk350 2011's brakes can fail to work even when there is no warning message and no warning noise.

Parked on a 45 degree slope. Placed the vehicle in neutral with the right foot on the brake pedal. Set the emergency brake down as far as the pedal would travel. Released the brake pedal with the emergency brake fully engaged. The vehicle started to roll down the incline. Local mechanic confirmed the brake system to appear fine as far as the brake pads and rotor (pads at 40%). taking this to the local mb dealer to review. I have video if needed.
