just wondering if anyone doesn't like Eco start/stop and would like to keep it always off. And if yes, is there any way other than pushing that button or change to your individual mode every time you start the engine?

The most annoying part of the stop/start is that after you put the car in park it will restart if you release the brake pedal before switching off the motor.

Penn, do you mean after setting the electric parking brake it does this?

Not yet get my GLC. But in my imagination to avoid it, can we:

1. park the car
2. gear to "P"
2. now your foot should still press on brake pedal, right?
3. push the engine button (if you have keyless go) and shut down the engine
4. electronic parking brake should auto apply even you didn't do that before you shut down the engine.

Is that workable?

^ The above is how I do it.

I have to say - this being my first car with start/stop - I was expecting to hate it. But it has surprisingly turned out not to bother me at all. The car switches back on so quickly, and the turning on/off is hardly noticeable.

I've had BMW loaners with it and it gets annoying in stop and go traffic but other than that it's not too obtrusive.

Turning off is fine. But I can feel a bit shaking when it's turning on, especially on a slope. At least it's not as smooth as how I can control the car without Eco Start/Stop.

My family own Toyota/Lexus hybrid car for a long time and personally I drive Prius/Camry Hybrid a lot.

For such engine stop/start, I have to say, these hybrid cars works really well. My best record on Prius was 600 miles in single tank driving ~

Do not have any start/stop experience on regular gasoline cars, GLC will be the first one. Very look forward to it..... still have 3 months to wait

I have had Mercedes loaners as well as BMW rental with start stop. Once you get used to it, it really not that bothersome. You can always deactivate it.

Penn

As long as you press the stop/start button before you take your foot of the brake it does not restart.

It seems really silly that a car that is in park with handbrake on will restart when the brake pedal is released unless you press the stop/start button first. It appears someone at MB stuffed up the programming causing the car to restart unnecessarily.

Mickfx

I think you need to think of start/stop eco as a state where the engine is really always in the on state. In "normal" mode with any car, you brake then move the tranny to park, then turn the ignition off. Putting the car in Park in stop/start - engine is actually still on until you turn the ignition off.

Penn

We just have to get used to hitting the stop/start button as soon as the car is parked this way the car will automatically be put in park and the handbrake applied.

No, Eco Stop/Start doesn't bother me. But that's because I simply DON'T use it.

It's so easy to go into Vehicle Settings and set up a Custom setting as I* in the Agility Select.

I just am completely used to now starting my car, and tapping the Agility Select lever to my I* and voila, Eco Start/Stop is off, until the next time I start my car and I tap the lever again.

Never had bothered me. I have been used to it since my E Class back in 2012. I actually feel good knowing I am saving a tiny bit of fuel at traffic lights.

dieseldoc

Does not bother me

My CLA does exactly this. It's super convenient.

I had a W205 C-Class loaner which didn't apply the parking brake when you switched the engine off. So I'm guessing the logic carried over to the GLC.

GLCer

For me, it depends, if regular commuting with some traffic lights and light traffic, I keep Eco on, but switch it off if its a very slow start stop crawling traffic or I am in line at McDonalds for take out, it gets annoying especially with the windows down you can hear the starter switching on and off all the time.

I wonder if its cheaper to burn more fuel with it switched off or prematurely wear out the starter motor with Eco in heavy traffic situations?

JEVA

I'm sure the starter is engineered to take the extra starts expected with this type of system. The battery may take more of hit.
As I understand it (and experienced) in BMW's the car will know if the battery level is dropping due to a lot of start/stop activity and will suspend the start/stop feature until such time it's recharged (from the alternator I'm assuming) sufficiently. Do MB cars do this as well?

GLCer

It has some built in logic circuit, at least on the GLC. When cold starting vehicle in Winter (20-30F or less) it doesn't switch off the engine with Eco ON, at least for first few minutes until engine warms up. Also if there is lots of start/stop, it will also suspend the Eco feature but I don't know what is the exact criteria for this to happen.

I'm using the feature but at the moment am neither pro or con. It functions ok except for the slight vib as the engine restarts. Am hoping the starter has been ruggedized.

mdsbuc

I know that BMW has a much stouter starter for their vehicles with start/stop, and I would expect that MB has done the same. BMWs have a reputation for having the harshest restarts in cars featuring this system. It hasn't bothered me and I use it about 70% of the time. I expect I'll use it about the same when I pick up the GLC.

With such highly frequency to start/stop engine, does anyone know long term reliability on battery, generator, motor, engine belt.....etc?

Penn

It appears that Brabus have a solution to the stop start issue.

All of our cars in Europe, including a couple of MB's, have had stop/start for several years. I don't notice it anymore and get annoyed when the engine keeps running when I stop. I actually dislike not having it in the U.S. because I don't like sitting in line at a light or drive-thru and knowing that I'm just sitting there spitting fumes out.

My wife wants a PHEV now which is considerably better than start/stop but MB doesn't appear to be making them available in the U.S. so she's thinking a Tesla Model X will do. :-)

I have this this feature in my car, but once I turned it off, it stays off. I don't like the feature and after utilizing it on a couple road trips, the gas savings was nominal at best.

Why do car manufacturers force you to turn if off each time upon start up now? Seems odd to me.
