For anyone annoyed with disabling the start / stop feature each time, you can pick up one of our OBD programmers that retains "last mode" for this feature, you can take a look at our vehicle coverages HERE. Pick one up today!
having the same symptoms twice ,once going slowly uphill,once going downhill with Costco premium gas. Scares the **** out of me as it happened twice when the car was moving slowly uphill or downhill at around zero degree celsius(32F) cold weather. Good job cars were moving slowly in the cold weather. Going to take it in to check. Hope they believe me at this has happened to lots people it seems since this thread was started in 2015.
ATTENTION ALL ~~~~~~~ I THINK I FOUND A FIX FOR THIS!
Basically this was random, but I never have this car stalled on me again after replacing the OEM BATTERY!!!!
Long story short, my battery went dead last spring. I didn't bother to bring the car back to dealership and called CAA to come change my battery, paid for a new one on my own pocket and the car did not stall on me again!
It is now 9-10 months of driving and I kept the car on its ECO ON/OFF, every time the car started back and kept on running.
Don't ask me the reason how a battery fixed this, I'm not an engineer nor an electrician. I replaced the battery and the car never stalled on me, this is a fact.
If you guys want to have a try, change to another non OEM battery and see.
Hope this is a real fix for this issue. Good Luck guys.

Thanks , will try that if issue occurs again.
Took my car in, ServiceAdvisor says no code found as in" engine did not die" just no power when accelerator was pressed down,therefore no code.Found nothing wrong(same thing happens to my Comand Centre when it had hiccups .It was updated and finally died and replaced) Updated car "SOFTWARE", advise return if it happens again. I will def replace the battery,maybe even with CAA, first then as it is WFH time and I have only done 11000 km( 7000 miles) in 2 years.
Hey guys, I had this happen to me 3 times now. When idling at the light (just started the car and drove out the parking lot at work), the car would shut itself off. All the warning lights will come on (It's not the Eco feature). I have to restart the car with the push start to reset it. Then it'll work fine. I'm going to have to find a way to film it next time it happens to show the dealer. ODB2 reader doesn't show any codes, and the car display is not showing any error messages. A few occasions I saw the RPM move up slightly and then back down; this happens right before the car engine shuts off.
Wondering if anyone else had this issue? i remember seeing someone else might have had this happen to them before.
I have, and this was caused by a worn freewheel clutch pulley on the alternator. That might be the case on your car.
Just post here 2024, for someone needed.
My w204 died in the middle of the way. Engine shutdown, all indicator show up, ESP inoperative,... It seems be ok if I start the engine and waiting 10min before driving.
Finally it was ALTERNATOR PROBLEM. I went to shop for cleaning, changed some minor parts. Now it running very well.
My 2023 E450 Cabriolet does this, since the day I drove it off the lot, it happened in front of the dealership and they told me not to worry about it, I should have left the car there

Thank you very much. I had the same problem and started following your instructions. Thanks
This severe issue seems directly related to... battery voltage and alternator powering the chassis.
For good measure, you can set your instrument cluster to display battery sensor voltage + current...live while driving.
There's a free experimental way to cancel voltage issues that yield more stable performance of both engine + tranny operating under 14.15V alternator control. It's effective right away !
What is crashing the ECU/TCU/ISM networking is the variable ALT voltage that impacts the CAN-Bus adaptability until it disables parts of it.
Chassis computers can adapt to tolerate harsh conditions with reduced performance... just not extreme with marginal networking.
The shortcut is simple: cancel the variable voltage factor!
Awesome reliable performance better than new.
