The number of people that are experiencing the same problem warrants attention. It's not just happening to owners of the C-class. I've seen people in the current S-Class forum report the same problem of the engine shutting off while stopped, but the S-class forum doesn't get as many posts/contributors as the C-class.

I'd be shocked if Mercedes doesn't eventually issue a recall for this. 5 years ago ABC News did a report (YouTube link below) on a similar problem happening to BMW's N54 engines except that problem happened WHILE DRIVING, not while being stopped like you guys are reporting. Report the problem to www.nhtsa.gov

What's the outcome on this issue with Mercedes? Any updates?

I brought my car in for 1) ESP + Collision Prevention Inoperative issue and 2) Car shutting off. They did a software update and asked me to monitor... we'll see if this is the right fix.

"22747 software attached das and battery charger and performed short test, found fault event codes, u0416fd, u0401fe, u140700, u0401fa, u0401fb, u041600, u0401fc, u0401ec in doc memory, checked for newer software in me, collision prevention assist modules and no newer software available, but new software is available for esp control unit, performed control unit programming and scn coding, checked tips and found tips document LI97.10-P-06219 removed right side kick panel and under carpet for water intrusion. no signs of water or corrosion found."

Not sure if this is related but the S Class Hybrid just got a recall for stalling. http://www.edmunds.com/car-news/2015...ling-risk.html

I have my car updated with the latest software but still happening... The engine stall and all warning lights came on at a traffic light. I saw the rpm went up to 1800 automatically then stalled. Good thing it was at a complete stop, imagine when I was driving and the engine rev up to 1800 suddenly and hit someone in front.

I've just experienced this for the 2nd time. In both instances the engine shut off at a stop light with the eco stop/start activated. I'm not sure what's causing it as I only notice when I try and accelerate after the light turns green.

I'm based in Toronto. Curious to know if anyone has received any feedback from local dealers. I'm scheduled to bring the car in for winter tires next week and plan on bringing this issue up.

Thanks

Let me know how that works out. I brought it to the dealer's attention but they couldn't duplicate the issue. It happened to me once with the eco stop/start on and this time without eco stop/start on still happens.

I'm not 100% sure it's fixed yet. I still notice a slight rpm move today. I'll monitor it for another week or two and see. I might get a go pro and try to record it...

Just saw this recall on the S class. Pretty much the issue I have. Wonder why the C class doesn't get recalled.

"The vehicle stall may be interpreted by the driver to be a planned shut-down as part of the ECO-Start-function. However, the engine will not restart automatically after releasing the brake pedal, immobilizing the vehicle and increasing the risk of a crash."

Saw this thread with interest, I've had the exact same issue with my C400 for over 2 years now. Uploaded a video of a more recent occurrence:

Curious if anyone else has had success having their dealership fix the stall issue, or reaching some other from of resolution with MB, particularly since the last post date in this thread?


Ironically, I've leased and serviced the car at MB Mississauga, who I've seen pop up quite a few times in this thread. Absolutely horrible service from that dealership relating to this issue. They've done everything from denying the issue exists, to replacing the transmission, engine plugs, and other components, all with the same core issue still happening. MB Canada has been equally unhelpful in resolving the issue, save for offering to sign me up on a new 3 year lease on a C300 at a higher price than I'm paying now.


Sincerely hope it doesn't take someone getting t-boned in an intersection before MB wakes up to the severity of this issue.

Not sure this is would help but the Eco Stop module from MidCity engineering allows the car to retain its last auto start and Agility mode:

You could permanently disable the auto start and see if that helps.

Sorry to bump an old thread, but just wondering anyone had a definitive fix from MB for the engine stall issue? I've been reading it could be corrected through software updates or replacing the crank sensor and pulse ring, but not sure if those were confirmed.

Thanks

I have a 2017 C43 and went to dealer to fix twice already. 1st time, they replaced the battery, 2nd time the transmission valve...
The car just stalled again yesterday.

I also want to know if anyone fixed at dealership and the issue was permanent fixed.
I'm in Greater Toronto Area.

DylanM

Took mine in and the techs diagnosed it as a faulty voltage dip limiter (similar to some others on the forum) - there was apparently a MB note on the issue. Hoping that's it.

SimMB

Same just happened to mine, 2019, C63s. Eco stop/start at the lights, lights turned green and nothing, just all the lights on and the button did nothing. Called SOS, while on the phone I tried it again and if started. Switched off the stop/start for the rest of the journey.


Think I'll be calling the dealer on Monday.

skylai

Yes, the car can restart again right after.
You will be just embarrassing to got stalled in the middle of the traffic and get honked at.

I went to the dealer again for the 3rd time and then I gave up. I just disabled the eco start/stop button all the time.

Peter Castle

Im having the same issue now! It will turn off! I call the dealer it didnt do it while they had it now its doing it more often and i was able to take videos! Did you ever find out what it was,??

SimMB

I didn't take it in as I didn't have enough time to get it looked at. Mercedes service did call me back and apologised, said we'd monitor it. Hasn't fine it since and I've driven with eco start. However, I work overseas so I've not been with the car for a few weeks. My wife has driven it, bit not that often and it hasn't reoccurred, if it does I'll report it again to Mercedes.

DylanM

Update - the stall happened again yesterday. This is after getting the voltage dip limiter replaced, so it'll be going in for another diagnosis. Anyone else have an update on alternate troubleshooting or fixes?

Same exact symptoms as before:
- Eco start/stop disabled
- Car driven a short distance after a cold start; engine still not up to temperature
- Stopped at the lights with foot on the brake
- Slight judder then engine stalls and all warning lights lit on dash; transmission shifts itself to neutral
- Restart the car - car starts normally with no warnings or CEL; have to shift back into D

This is quite dangerous, so I'm going to be escalating this up through Mercedes Corp

any update?

DylanM

Tech checked and there were no stored codes, and they couldn’t recreate (exactly the outcome I expected).

They will be trying to get the issue to reoccur over the weekend - if they can’t, will see if a TIPS note can be escalated to MB. If any others are having the same issue, I’d recommend pushing for a tips note as well (it’ll help the engineers pull in multiple data points - especially if they need to issue a TSB).

mordekaiser

sorry for bumping this thread but have there been any solutions found for this issue, Dylan? I own w213 e350d and experiencing same exact symptoms as described in your previous reply.

DylanM

Hi there - yes they were able correct it with two separate software updates. I'll try and see if I can find the specific references in my service records. If you have the same symptoms, you can ask your service department if there is now a TIPS note.

Hey i had the same problem with my 2016 cla250 4matic. I faced the stalling problem like 2-3 time a day. I got it checked from mercedes benz first but they denied that nothing is wrong with the car because it doesn't give any engine code. Then i got it checked from a mechanic outside. He told that my fuel pump was faulty. Then i again went back to mercedes benz and asked them to keep the car for 2-3 days and take as much time they want... Then they agreed that yes the pump is faulty and they replaced it... Its been 2 month now and car is running really good without any problem.

Amrit Saini

Its the faulty fuel pump problem. I had same problem with my 2016 cla250. Benz replaced my fuel pump under warranty and everything is running good now.
