GLC 300 Not moving forward

I was at a stop sign, when I released the brake and pressed on the gas to go forward, the car did move forward but very slow and was stuck in D2. No warning lights came on.

Problem went away after pulling over and turning the car off and on again.

Any idea what could have caused this?

Did you try to manually upshift? Possible you had the manual shift button on the center console depressed and therefore engaged?

I don’t think so. I remember clearly seeing “D2” in the display. When you use the manual option, it should say “M2”, right?

one thing I didn’t mention before is that the day prior to the issue, I drove with an almost empty tank, I don’t know if that would have caused any damage.

Unlikely the cause to the shifting issue but anyways don't do it again as low fuel means the fuel pump doesn't have fuel in the tank to cool it down.

For the shifting issue if it doesn't come back it might be a one off, if in doubt you could see if there are any codes stored with a scanner..

You know the vehicle starts out in D2 from stops when driving in comfort mode, right?

What year is the car and how long have you owned it?

Normal. Helps save fuel, older MBs that did this like the GLK will roll-back but I think MB has the "hill-start assist" or something along those lines.

I'm aware it's normal. I was asking the OP if he knew about the "feature".
