Brand new MB C300 owner here - picked up a 2010 with 14K miles on it over the weekend and I'm absolutely head over heels in love with it!

I did notice something kind of strange though after driving it for a couple days now - there seems to be about a 3 second lag after I shift from reverse to drive and hit the gas before the car actually responds. When I put the car in drive and hit the gas, nothing happens. There isn't any sputtering, weird noises, or anything like that - it's almost as if the gas pedal just doesn't do anything (despite being pressed down) until 3 seconds after the shift into drive has been made.

Has anyone else experienced a similar issue? Is it normal for this car? I do have the autolock feature engaged, so I'm wondering if that could be the culprit.

Thanks so much for your help!

Is the delay actually the transmission changing gears? My C would take about 3 seconds to shift from park to reverse. I took it to the dealer and there was a software update for the transmission which resolved the problem. Regardless, it's under warranty so I'd let the dealership have a look at it. Best Regards,
Ben

Welcome to the forum BTW and congrats!

As mentioned above,,,,take it to the Dealer, they can fix it.....software update.....

mine was even worse, it would take up to 10 seconds to engage.....

Thanks guys - I'll see if I can swing by this weekend and get it looked at. Glad to know a couple of you have also experienced it which must mean I'm not totally out of my mind...

I noticed the same thing, but I thought it was me being impatient since I switched from my manual transmission SLK.

That's sort of where I stand. Not totally sure if it's the way the car is supposed to function or if it's me being impatient, but being that a couple folks said there was a software update, I think it makes sense to at least go and inquire / get it checked out.

Yep. As others have stated, it's a well known problem. Even though the lag seemed like only a few seconds it felt like eternity when parallel parking with people waiting behind you. Software update=easy fix.

I went today and scheduled a appointment for the update. I talked with a service advisor first and she already knew what I was talking about and said there is a update for this

Same thing here. After seeing some posts on this forum, I brought it in for the s/w update and it's been great ever since.
