Hello together, have a G63 (built in June 2013) since nearly 1 1/2 years in my possession and unfortunately two recurring problems with the car. On the one hand the sliding roof whistles from a speed of about 180 km/h loud, on the other hand the steering makes during parking, shunting and narrow short loud squeaking noises. I was already several times (5 or 6x) due to both problems in the Mercedes branch, the problems were fixed every time briefly, but are i .d.R. reappeared after one to two days. A lot was done, for example, because of the pipe on the sliding roof once the roof antenna was installed, sometimes even a new reinforcement than the normal one. On the steering wheel everything was tried out with different special greases, even a new steering column got my G63… nothing helped. Also multiple contact of the NL to the plant did not bring anything, the errors are allegedly completely unknown at the plant (as with the NL itself). Are there G63 drivers or drivers of other G models with the same problem(s)? Look forward to the exchange. Best regards, flip
