Delayed (Several seconds ) throttle response
All,
I'm an owner of GLC350 with 30k on the car, I've noticed that at times when I press a gas pedal, there is absolutely no reaction from the car at all. I'm not talking about a turbo lag or slow acceleration. I'm talking about a complete absence of any response from the pedal. An especially dangerous situation when you come to a rolling stop trying to make either left or right turns, you are dead in the water at times for several seconds where the car is just rolling and only after 3 - 4 seconds it actually responds to the accelerator. The most annoying thing is that it doesn't happen every time. Any advice?
Thanks,

GLC43
Ive have ( or had ) exactly the same problem with my GLC43.. Just recently had it in for them to look at this problem. With it being so intermittent, its not going to be easy to find. They have done a transmission software update and some other engine software update as a starting point for now.. Its early days, but so far so good.. Hard to say if its actually fixed the problem, it could take a month or two between faulting, it was very intermittent.... Did you ever have the fault occur travelling in a straight line? Or only when turning? I'm pretty sure i had it in a straight line, but more often it was when i was turning..

I have the same issue. 2018 GLC 300. Usually for me in the morning when just starting out and I come to rolling stop while turning left. No response for a few seconds. Happened a few times turning right while entering a busy road with oncoming cars. Thought I could just accelerate onto the road but had nothing. Have not brought it in for that yet. Figured it was just the trans searching for gear since I didn't stop fully. I don't think it happens if come to a full stop or almost full. Usually when coming to a rolling stop with some acceleration first.

Don't know if this applies to the new glc models but definitely worth a try.

Happens once in a while with my E300 - feels like transmission will not re-engage and then engages. I hate it a lot, but I feel like it is a characteristic of the transmission, which tries to "coast" to save fuel. If I am going to make a left in front of traffic or do something that requires immediate response, I try and roll forward a bit to be sure the transmission engages...

I'd get them to do a software update on the transmission if there's one available.. It would be a good starting point.. Mine hasnt given me any trouble since the transmission software update...

I have done the reset procedure twice and it has helped the overall shifting of the car. I did not initially do it for the delay issue but it has helped with that as it turns out. I did it because in overall driving the trans had lost the smoothness I was used to and had read about the reset. Worth a shot. After the last step of turning off the car and releasing the pedal, make sure not to touch anything for about 2 min.
