MBRACE Remote Start... turns off on door open?
Anyone use the remote start from the app? I love using it to start my car with the AC running to cool the car before I get in when its parked inside.
However, whenever I open the door the car turns off and I have to restart it. Any idea?

That's by design unfortunately. Intended to prevent someone else from attempting to steal the car once it's running. The remote start function only works some of the time for me, usually fails. When it does work I start it about 10 min before I drive so the car has time to warm up / cool down.

Yup, by design. And I HATE it for the same reason you mentioned... I just don't feel like it's good for the engine, although I'm sure they've done their research and testing. Not to mention you're not supposed to warm your car up idling, but rather easy driving to get temps up quicker. Not that any of this makes a difference anyways in today's cars, but maybe it's force of habit.
I never use the auto stop start feature either for the same reason.

Yes, and it's a disappointment. I remember the first time I remotely started it, it was very hot (I lived in central Florida) and the family was looking forward to stepping inside a cooled environment. As soon as I grabbed the driver's door to open it, the engine shut off. Bummer! It's unfortunate that the few cases where someone had their vehicle car jacked from being remotely started causes everyone else to miss out on the feature. Who knows, maybe some car owner had remotely started their vehicle, and as soon as they opened the door, some bad actor was right there and car jacked them. Then the vehicle owner sued the car manufacturer, reasoning, "It's your fault because you included this feature", ha-ha.

I know this thread has died off since now yet I don’t see how other car makers can make it work. Remote start the car. Need key fob to unlock doors. Then push start and magic the car can then drive away. The annoyance of buying a new 17 E class and still the lag in progress with certain features. Granted I am not taking away from all their success with other features. Maybe i’m just upset since my car sits outside in the cold of Chicago while the race cars and fiancé’s car stay in the warm garage haha.

I don't know that it's a lack of progress as much as Mercedes choosing to design it that way as a safety feature. Perhaps a running Mercedes with nobody in it is a more likely target (more expensive target) than a Chevy whatever that nobody would steal even if it was sitting there running haha.

Haha I hear ya. I mean the car should be locked, need the fob or key to unlock the door, then read the key to turn over power to then drive the car. Just seems like something they make an annoyance just like the darn eco start stop haha.

hey. It is by default by mercedes. I had a Honda Accord Touring 2017. beautiful car. It could start and than you sit in the car and press start once and car stays on and ready to drive. Coming this from Mercedes, It is pretty stupid. I did check with the dealer and he said " it comes like that" and I told him the same thing. On a benz, its stupid.

your right in many ways but when the card is remotely start, the doors are remain locked in most of the cars. on my c 300 2017, if I unlock the car in any way, App, remote or door handle, its shuts off right away. I have to start it again from inside the car. I wished they set it up where if you unlock from the remote, it stayed on.

As for the remote start cutting off when you open the door, be thankful. There have been a series of reports of car thieves using key transponder range extenders to extend the keyfob signal from inside the owner’s house to the door of the car, unlocking it, and driving off.

Ummm I’m pretty sure that’s impossible. You can definitely get the interior warmed up/cooled down (depending on the climate you live in) and the engine water/coolant temp up to normal operating temperature, but even on the hottest of FL days, after running the remote start for the full 10 minutes, the oil and trans temps are still well below operating temps. That requires circulating the oil under load and the trans under load.

Oh and FYI, an easy fix for the aforementioned security flaw is to double lock the car with the keyfob, thus effectively disengaging the keyfob from the touchless entry mechanism. There’s a thread about it on the forum somewhere...

In our Caddy the doors are locked and you enter the car still running. Without the fob you cant enter the car and if you do your not going anywhere in park.. In our Subaru doors unlocked car running from remote start as soon as you touch the brake the engine shut off. All things MB could incorporate. Plus because the Me app has issues and doesnt always work a fob remote would be helpful for remote start. Or is it that MB just wants to make more money with Mbrace ?

It’s pretty much a useless feature and I was shocked remote start wasn’t on the key fob when I bought mine....first Benz so just assumed they would have it since every other maker, all price ranges, typically have now.

The Infiniti or Acura I had would let me in and just hit the start button (to keep the car running).

My Lexus did that but my Dodge didn't, some manufacturers are more careful.

I don’t really understand how this behavior is safer…
