Power steering malfunction car unable to drive I believe there is supposed to be a recall for this issue but not popping up when I put in VIN number warning lamps come up. Sometimes every light on dashboard. Took it to mercedes but it was when code was not popping up and they said I needed a new battery. Did that but still an issue. Has also happened when driving. Sometimes collision assist plus light comes on and power steering acts up. Light I am pointing at in picture is another light that consistently pops up I have been able to intermittently fix problem by resetting computer by unplugging battery for 15min or longer. As well as confirming full service on vehicle. Now it isn’t working though.

My car is a 2015 Mercedes Benz, I bought it at the agency in 2022. When I tested the vehicle at the agency, I noticed the steering was a little hard.

I went to work and the steering wheel jammed and it wouldn't cross and the car turned off then it didn't want to start and it said the following on the dashboard power stering see operator manual.

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.

Power steering malfunctioned while driving. Received error on dash. The steering wheel was very difficult to turn. Issue was resolved after turning the car off for 5mins and restarting. However it is unclear whether the issue would fester again. This is the first time this issue occurred between 2017-2022.

The C300 4matic specifically should be recalled because something near the front end squeaks and makes all types of noises.

I have the same problem about steering harder when on lower speed, every oil level looks to be perfect.

Loss of steering while driving vehicle. Extremely unsafe. Error message displayed frontal left malfunction service required. Vehicle inoperable. Steering wheel just spins no control of vehicle.

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.
