Hey guys,

I'm new on here, I use to own a rx8, wrx sti, cls63 and a ford ranger which I all adore.

2 years later I've come around to getting back in the game and ordered a new AMG

I was wondering if someone could give me a helping hand or information for the issue that has arisen for me and my brand new car.

3 weeks ago, just picked up my new 2019 sedan C63s from the showroom in Sydney Australia
I have picked it up on a Monday, diving to and from work in normal order as I have to run in the engine.

The following Saturday night was when the problem arose while driving back home after a night out. (the problem happens while im in idle -> acceleration/reverse) I was stuck in traffic and I have my foot on the brake. As I let go of the brake to edge forward I would feel the car pushing forward. I started to notice the RPMs would go up by itself from 800 to 1200 for no apparent reason. (I also made sure at the time my foot wasn't awkwardly on the accelerator and the brake) Mind you I almost hit the car in front of me twice as it just started to happen. I also then noticed when it wasn't doing this it would struggle to get into momentum as if I was driving manual from neutral to first gear trying to accelerate the car and it would jerk a few times then go.

Finally reaching home I then put the car into reverse and it struggles REALLY HARD to move, it had felt like it was going to stall. I would accelerate and the vehicle would not move then suddenly thrust.

I take the car back to the dealership the next day and asked for them to look at it as I was furious what is happening. They told me they didn't have time as service was not open on a Sunday and to come back the next day. I told them the car was not deemed safe to drive and it was a hazard, they thought I was over exaggerating.
Finally, the salesperson that sold me the car said he'll come to take it for a drive around the yard to see what is happening. He noticed there was something that wasn't right about the vehicle, told his manager and said leave it here and they'll take it in for service the following week.

So here I am 2 weeks away from my brand new car that hasn't even hit 100kms on the odometer. Three emails were sent to me since then.
1. First 2 days: We don't know what's wrong
2. Next 3 days : Still trying to figure out what's wrong submitting a sample of engine fluid, and awaiting for Germany to reply back.
3. Latest reply: The next step we need to carry out is an adaptation of the gearbox on cold and when the vehicle is hot. This process does take a few hours to complete. ( aka still not sure what is wrong)

Has anyone come across anything like this or heard a similar story?
In Australia there is nothing such a Lemon Car Law, all we have is ACCC, CHOICE and Consumer Buyers Protection which is really vague and grey.

It is just doing my head in as I have paid good money for a product has had it less than a week, more so they don't even know what is wrong with the vehicle.

Hope to hear back from people with some experience.
Many Thanks

PS. when I picked up the car they could not connect the car to Mercedes Me ( a new system ) and still haven't able to.

 

I too have the same problem. I just got my car yesterday and today it stalled two times when i was completely stopped at a traffic light when i try to start it again all the light turned on and when i keep pushing the button for awhile, it will start completely fine with the check lights all gone could you help me figure this out too? Its brand new not even 80 miles on the odometer

 

That's so sad to hear, especially with a new ride that you just picked up. In this forum, this is the first I'm hearing about unintended acceleration and stalling issues. There have been misfire related issues few folks have had, and they had the coil packs (and few other parts) replaced to fix those I believe - even with the Facelift models.

Is there a mbusa equivalent for Australia? You could try reaching out to them directly (either over phone or email), explain the issue in detail and see what they say? Also having things in writing (eg. emails) might be good just in case you need proof of the concerns you had and you had contacted the MB Australia division to let them know.

Definitely ask your dealership and service department to explain in detail (again in writing) about their diagnosis, and what are the next steps.

 

This is what happened to my car. The dealer wasn’t able to duplicate the problem after I took it to them. Take it in and push the issue with your service department, tell them you don’t feel safe driving the car.

Start there and maybe get Mercedes corporate involved.

Good luck!

 

WOW! This is very disheartening! We've ordered 2 x C63s which should be arriving end of this month (ship is scheduled to dock on 19th). Having previously owned many cars, reliability has never been/was a concern. I can make do with random rattles or squeaky seats but having your brand new car stuck in a workshop for weeks on end is completely ridiculous.....especially for a car which is priced at $185k!! (AUD).

I understand most of the posts in forums are regarding people experiencing issues (no one posts about how reliable their car is) however reading these types of posts really makes you nervous.

Ironically I waited over 1 year to order the face lift model thinking as most of the teething issues will be rectified however it appears it has gotten worse.

As OP indicated, we don't have lemon law in Australia so you are pretty much screwed if you end with a lemon so I guess all we can do is cross our fingers and hope for the best.

 

My 2019 C63 Sedan is at the dealership currently with 1800 miles waiting for a new transmission from Germany as mine was leaking out of random areas on the case itself. My 16 sedan and 17 convertible were absolutely bulletproof and it seems like whatever they have done to these 19s is not faring well.

 

Interesting, my first C63S was a 2017 and after 54 KMs the transmission quit working, wouldn't go into gear. To my surprise there was a new transmission in Canada so only had to wait a few days for it to be shipped across Canada to the west side.
