My new GLC220d had a broken stearing column adgestment and failed to move up or down. All stearing position adjustments was electronically controlled and When trying to do this with the small liver it gives a loud cogwheel grinding notice and the steering is stuck in a high position. The GLC is only 7 weeks old and done only 1100 miles. Took to the dealer who informed a gear link in the electric motor mechanism is broken and kept the car overnight to replace the broken part. Will update once the car is back.
