Failed component: power steering. Mercedes Benz of Princeton did the replacement, but we're not sure if they kept the part. Safety issue: On June 14, 2022, the vehicle-€™s power steering failed in the middle of a drive (see attachment for the error message). This was a major risk since the car was stuck in the middle of the road, with the steering wheel requiring tremendous force to turn. Luckily, we were a few 100 feet away from home, so we just left it. Next morning the car turns on fine and there are no issues with the steering. One week later, on June 19, 2022, the issue resurfaced. This time we were driving 35mph in a public street with traffic behind us. We were barely able to pull the car over to the side of the road. We took the car to Mercedes Benz of Princeton where they diagnosed the issue and quoted $4551 to replace the entire steering rack. We also contacted MB USA to understand why our vehicle wasn't recalled as part of NHTSA Recall ID #15V-845. After dragging their feet for a full month (where no updates were provided), they denied the claim. On July 22, 2022, we ended up paying the full cost of repair and lost the use of the vehicle for a full month.

I sat in the car, had not started it yet, and a "power steering malfunction, see operators manual" warning in red was on dashboard screen, and another smaller red indicator light of a steering wheel was on in the speedometer area. Started the car and the warnings remained. Shut it off and immediately restarted and the warnings remained. Starting driving the car and the power steering was indeed out. I had great difficulty trying to steer, especially under 5mph. Drove about a mile and then parked and shut the car off. Came back about 10 minutes later, restarted the car and the warnings were gone and steering was back to normal.

Electronic controlled steering failed. I could not steer vehicle.

- Clarksville, TN, USA

The steering malfunction light came on and the steering wheel lost power. The steering wheel locked up where it become extremely difficult for me to maneuver the car. I put on my emergency indicator and got the car into a parking lot as safety as I could. Had this occurred while I was going on a road with curves or at high speed, I believe I could have suffered severe bodily injury. I called mbrace to get my car towed. When I turned my car back on after approximately 5 mins, the error was gone and it was close to 7pm and the service center for the dealership where I purchased this car from was closed. I dropped off the car at the dealership the next morning. Today is the second day and my dealership tells me that they opened a case with Mercedes as their was a faulty code in the steering electrical box and they were advised by Mercedes to simply reset the box and drive the car for some time. However they could not tell me why it happened and whether the reset will prevent the occurrence of the steering wheel malfunction again. I refused to take a car back until its safety is proven. The dealership is keeping the car until they hear from Mercedes which according to them could take a few days to a week+. I purchased this car approximately 3 weeks ago and to have a major issue with my car with and the dealership and Mercedes to provide no confidence in the safety of this vehicle is extremely appalling.......updated 12/17/15 updated 10/11/2017

I started the engine and the power steering failure warning came on. True enough, it was a struggle to steer my car back home - I was just 3 minutes away from home. The car was towed the next morning to autohaus on edens in northbrook, il. I did a google search and found out that there has been a recall for this exact problem in europe since Dec 2014. I was shocked that owners in the us were not warned of this potential problem and there has been no recall issued. If this had happened on the freeway, it likely would have resulted in a very serious accident and my safety could have been jeopardized. I would like other owners of the 2015 Mercedes Benz C class to be alerted to this potentially serious mechanical problem and the nhsta to investigate why there has been no recall issued in the us......updated 12/17/15 both axles front axles had to replaced.
