HELP: 2018 GLA Randomly Stops




She's had this car for about 3 years now. Recently it has begun an annoying and dangerous problem. Her car will just randomly bog down and stop. In order to restart it, she has to epop off teh push button ignition and use her "hard" key to restart the car. It has not failed to restart yet, but still...this is very dangerous.
She's had the car at MB dealer twice for diagnosis and they say "all is well". Can't replicate problem.
She had the battery replaced in December but otherwise has had no other difficulties.
I searched this forum for similar issues and did not find anything.
Can anyone here offer any suggestions or point me in another direction?
Thanks in advance for everyone's insight and help
Jeff




It was a certified used car so I am confident she is still under the extended warranty of not the original factory warranty.




No other warning lights were present.
