Some of the common problems I observed reading here and also in the GLC 300 group on facebook.

1) battery discharged within a day.
2) The car refused to go onto 'D', and it usually comes with a stack of inoperative messages.
3) Active emergency unavailable / active emergency inoperative while driving
4) The GLC suddenly tighten the seat belt as though you are already gonna have an accident.

#3 - fuse problem? mine had a new steerling wheel, main control unit and software update. Still didn't fix it. Kind of given up, car is going back in later this month.
#4 - not sure.

Even on the first day after bringing the car home and then going for dinner later that evening I noticed some issues with the transmission. Taking off from a stop light required a lot of throttle and the transmission would be rough. Going up inclines at slow speed the transmission seemed to be confused about which gear to shift into (driven in comfort mode). And then when reversing the car did not want to reverse slowly and would buck and judder. I tried not to think about it too much and put it down to maybe not being used to the throttle sensitivity driving a new car but I knew it was wrong - my other cars are a GT3 and F8 so I feel I have experience with sensitive throttles. The next day I drove the car and I didn't experience as many issues but still noticed a jerky reverse gear.

Then on Friday the 29th my wife took her mom out to shop and after a few hours when they wanted to leave the car would not start and kept flashing a "Fob not Found" error. She could unlock and lock the car and turn on the display and play music and charge her phone but the car just refused to start, even after placing the key in the designated area in the console. I thought maybe it was just the key so I left work early and brought the second key but still no dice. Tried everything for an hour and couldn't get it to crank. To make matters worse the car was parked in an underground garage so not easy to tow out.

Thankfully the dealer sent a GLE350 as a loaner so I could go home and it drives MUCH smoother. None of the transmission issues I noticed in the GLC. I still don't know what is wrong with the GLC and not even sure if they were able to get the car out of the garage (tried to forget about it over Easter) but the experience after two days has been BAD.

It feels like the car doesn't respond for a second or two. Not to mention the ANNOYING rattle from the center console behind the navigation screen. Finally got rid of it by shoving some pieces of rubber behind the nav screen. It's a shame this is the case in a $75k vehicle.

~400 miles on the clock. Beginning to think the GLC is just garbage.

I think Mercedes is fighting a 48V uphill battle if they think they can force every American to think like they do!
