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.

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.
