My GLC 250d 4matic Sports Premium Plus is just under two years' old and has done just over 8,000 miles. Last week, we were travelling along the autoroute in France at 130kph when the power steering failed. Luckily, we were in the inside lane, the traffic was light and I managed to guide the car off the main carriageway at the next exit slip road. I won't bore everyone with the chapter and verse of our rescue but the car is now with the local MB dealership, some 3 and a half hours from our holiday home. They have identified the issue as a problem with the steering rack, which needs replacing. However, MB tell me that they are unable to source one in France or Europe. The issue has been 'escalated' to the highest level at MB Assistance but, one week on, the car is still marooned. I had a very similar problem last year, again in France, when they were unable to source a replacement windscreen without a considerable delay.
Has anyone had a similar problem with the power steering i.e. a complete loss while driving at speed? And have there been similar problems in obtaining replacement parts? I find it extraordinary that a global company of MB's stature is unable to find replacement parts on a timely basis.
