Other steering problem on the 2015 Mercedes Benz C300
When other steering problem gets reported
Owners of the 2015 Mercedes Benz C300 report other steering problem at a median of 15,000 miles. A quarter of the reports come in before 10,000 miles and a quarter after 40,000 miles, from 9 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 7th most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 60,000 miles at the ninetieth, a spread of 56,205 miles across the middle 80% of reports.
A window that narrow is the signature of a part that fails on its own schedule rather than on how the car is driven — which is usually a design or supplier problem rather than wear and tear.
67% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 2,995 miles | 8,000 miles | 17,000 miles | 40,000 miles | 59,200 miles |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Putting it right typically runs $350–$2,400 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 8 model years of this car. It shows up earliest on the 2015, at a median of 15,000 miles, and latest on the 2013 at 95,000 miles.
By volume the 2008 carries the most reports, with 56; the 2015 has 15. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
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…
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.

How far this goes
Complaints are voluntary, so 15 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.

How common is other steering problem on the 2015 Mercedes Benz C300?

What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
