Car Turned Itself Off
Well, something new happened to me yesterday. As the title says, the car turned it itself off fully when I had stopped in traffic. Good thing it didn't happen when I was moving..
The Situation:
- Driving in the city, Comfort mode, auto-start/stop set to Off (I always set it to Off).
- Stopped at a traffic light and suddenly everything powered down except the radio. All the dash lights/icons come on and the steering wheel locked. It felt like the car just died.
- This is very different than when auto-start/stop (***) is engaged because: 1) you get a a green indicator on dash when *** activates, 2) you can still move the steering the wheel when *** activates (which in turn starts the engine again).
The Solution:
- After a couple of seconds of confusion, a quick restart of the car solved all problems and I continued on my way. It has only happened once (knock on wood).
Other Thoughts:
- The car is less than a month old, so I doubt there's something wrong with the battery
- It was cold outside (~15F), but it's been in colder temps without issues
- There were no indications of anything else going bad or sounding weird either before the car shut off or after it was restarted (e.g., no signs of fuel pump or water pump issues, limp mode, etc.).
- I think I'll just chalk this up to a glitch??
Has this happened to anyone else?

It would not restart when you released the brake or applied throttle?
If it really stalled out, the cause is as likely to be bad gas as it is to be an actual fault in the car's electronics. If the car was already running, the temperature or battery should have nothing to do with the stall.

Did the car shudder and then "die" (w/ all the warning light coming on and the steering locking) almost right after you came to a stop?
Our 190E did that, as did my 2012 C250 (very recently, actually). In both cases, the transmissions had to be repaired (entirely replaced, actually, in the case of the 190E).

Thanks for replies all. In response to some of the questions that were raised:
- I don't remember if the transmission stayed in Drive. I know that after the restart, I pulled the shifter down to Drive out of habit, but I don't know if it had already been in Drive.
- I definitely was not in Eco Mode. I've only put it in Eco Mode once and that was just to test it after picking up the car from dealership. If I had accidentally pushed the toggle to Eco Mode, I would've noticed it on the big screen.
- The car didn't shudder right before shutting down, which is why I am thinking this was more of an electronic glitch. It also had no problem restarting back up.
- I call the system "***" simply because I'm used to what the Bimmerpost forum members call it on BMWs
- Bad gas? Maybe..? I've only filled up the gas once so far and I use top tier gas (Shell). I have no idea what the dealership filled it with the first time and there are probably still traces of it mixed in the tank after my first fill up.
I'm guessing that if it's a transmission issue, it's likely bound to show up again at some point.. preferably within the warranty period if at all. Still, it might be worth bringing it in just to see if it threw a code at all.

The most likely cause is an electronic brain fart. Can happen ~ restart reboots all processors.
Monitor it. Read codes with a scanner to see if anything is stored. Can be the EIS but might just be a one off. Can happen with the modern car.
Imagine if Microsoft designed it.

The 190E and C250 also re-started w/o a problem. I don't think the car can be turned on unless you return to "P," so you might've pulled the gear lever to "D" after re-starting for that reason.
The C250 didn't give an error code, if read the service report correctly.
The 190E would only die once every couple of months (if even that). I've had no issues w/ the C250 (which I bought in Feb. 2012) until this past Dec.
The service people (conveniently) couldn't find a problem w/ the 190E until AFTER the standard warranty had expired (fortunately, my parents has an extended warranty on the car). They decided the curative action was to give us a re-built transmission.
A different set of service people decided to replace a transmission solenoid on the C250.
Do keep us updated. It'll be interesting to hear what your service people have to say.

Yes ~ the transmission can trigger a severe limp code that will cause a shut down but it's extremely rare.

A buddy of mine had his rover in for a month trying to figure out the exact same problem... While driving the car would randomly shut off when at low speeds

There are different limp modes on Benz for transmission issues. Most will allow restricted performance but get you home. Total shut down is unusual but possible.

Well, something new happened to me yesterday. As the title says, the car turned it itself off fully when I had stopped in traffic. Good thing it didn't happen when I was moving..
The Situation:
- Driving in the city, Comfort mode, auto-start/stop set to Off (I always set it to Off).
- Stopped at a traffic light and suddenly everything powered down except the radio. All the dash lights/icons come on and the steering wheel locked. It felt like the car just died.
- This is very different than when auto-start/stop (***) is engaged because: 1) you get a a green indicator on dash when *** activates, 2) you can still move the steering the wheel when *** activates (which in turn starts the engine again).
The Solution:
- After a couple of seconds of confusion, a quick restart of the car solved all problems and I continued on my way. It has only happened once (knock on wood).
Other Thoughts:
- The car is less than a month old, so I doubt there's something wrong with the battery
- It was cold outside (~15F), but it's been in colder temps without issues
- There were no indications of anything else going bad or sounding weird either before the car shut off or after it was restarted (e.g., no signs of fuel pump or water pump issues, limp mode, etc.).
- I think I'll just chalk this up to a glitch??
Has this happened to anyone else?

Yes, the exact same thing happened to my C400 3 times between (Sept 2014 - June 1, 2015).
The 1st time was probably in Dec 2014, I didn't know what it was at the time, I was just stopping for a red light, lots of cars waiting behind me so I was in a rush trying get the car going just exactly like what you were doing.
The second time (May 23, 2015) was a cold start, in Comfort mode. my wife was driving for about 3 mins, stopped for a red light, same thing happened. She got panicked (who wouldn't) at first but manage to start the car.
The 3rd time which is today (June 1, 2015), it was in Sport mode and also a cold start. Stopped in traffic for a red light. Foot on brake paddle, applied pressure to activate brake "HOLD" function, the car's engine start/stop kicked in. Engine went into engine stop mode. Then all of a sudden, I felt the brake paddle pressure got released and the paddle lifted up as if the electric parking button was pressed. I then noticed all the lights went on including the parking light (that explains why the brake paddle pressure changed). The car is now stalled. The Gear went into P mode. I had to press the ignition button to start the engine and put the car in D mode to start driving again.
I took the car in to the dealer the same day when the engine shutoff the second time on May 23, 2015 and left the car there until May 27. They couldn't find anything, no error code)
I will report this 3rd time to the dealer again tomorrow.

I had the same issue three times. No fault codes stored. The last time the dealer did an ECU update, so far the problem hasn't returned. I did notice that right before it happens the rpm needle moved a bit while the car was stationary and no gas was applied.

Hi jclboston, Have you experienced any more of this engine shutoff any more after? Have you taken your C400 to the dealer?

Could be buggy software where the car thinks turning itself off is normal under certain parameters if there were no error codes. Keep us updated with the latest dealership visit.

Add 1 more C400 to the list. My wife just called to tell me this happened to her today. Car had only been running (Comfort Mode) for no more than 4 min. She said she came to a stop and the auto off kicked in...... Dash lit up like a Christmas tree. She restarted the car and continued. I have 11k on the car so it was a surprise.

Twenty years ago when a car stalled at the lights it was called driver error & no one had a second thought.
Today it takes pages of explaining on a website.

Hi Dkinsley,
My car has been in the shop for diagnosis for a week now. The dealer is in Richmond, Vancouver, Canada. They have been working with Canada and Germany headquarters on this issue. I suggest you take your car in ASAP and make sure you tell your service advisor to get in touch with my dealership and also report to Germany about this.
Where are you located?

Add 1 more C400 to the list. My wife just called to tell me this happened to her today. Car had only been running (Comfort Mode) for no more than 4 min. She said she came to a stop and the auto off kicked in...... Dash lit up like a Christmas tree. She restarted the car and continued. I have 11k on the car so it was a surprise.

It has not happened to me since that one time in February and I did not take it to the dealer. Then again, I only use the car once or twice a week at most, so not a lot of seat time. It's definitely concerning that it has happened to you multiple times (fortunately, at least you were stopped).
Could be buggy software where the car thinks turning itself off is normal under certain parameters if there were no error codes. Keep us updated with the latest dealership visit.
