Why do we hate Auto Start/Stop so much?

[Green/22/Bronco]

I have a bmw x3. I hate this feature. I was on the phone with my daughter, pulled into the garage and had my foot on the brake while I spoke to her. The engine shut off, of course. When I hung up, I thought I had shut the engine off, took my foot off the brake and the car started and almost went through the back of the garage. Really scared me. That feature can be dangerous. Happened to my husband too. Bmws are also very quiet when running, which doesn’t help. I no longer use this feature.

I have a BMW X1 m35i and it’s far from quiet. Depends on the model.​

the dangers of automatic transmission.
we should all beware!

But facts have proven that isn’t the case-the last time I replaced a starter on something was almost 30 years ago-and it was a Bradley, not a car.

Your logic is like if I don’t spend any money, I’ll have four or five times that amount lol

He did not say that he would have four or five times the starters, and yes , if you don't spend any money what you do have will last longer .

Ban Automatics, problem solved xD

Ban automatics? That would take 97% of people off the road! Great idea.

Considering how bad most of them drive to begin with, is that truly a bad thing?

Seriously though, too many tards driving slow in the left lane glued to their phones who have the balls to get angry at us for honking/flashing them to pay attention and move over

This is my first vehicle with start/stop so I was curious. I ran 2 tanks of gas through with it always on and 2 with it always off. Exact same driving conditions for both tanks. I averaged 20.1 without and 20.3 with it on. The difference is not worth the wear and tear for me.

Has anyone else gotten different results showing greater MPG with start/stop engaged?

 

[TX-Dennis]

That's about right. The difference is real but small.

The auto start stop doesn't bother me. I've noticed no lurching or delayed starts that others have mentioned. Then again, I'm not hot rodding it from light to light with one foot on the brake and the other on the gas. The restart is basically instantaneous when I start to lift my foot from the brake pedal.

Just bought my first bronco (yay!) and I am getting used to the start/stop feature. I was aways told. turning off the vehicle and back on will wear out the ignition. Is there any truth to this? Is it hard on the vehicle overtime to turn off and back on? Sorry if that's a dumb question.

This is the answer

I'll vote for the first presidential candidate that promises to put an entire FBI team on tracking down the guy who came up with the auto stop/start feature so he can be brought to justice.

Worst. Idea. Ever.

I've always been uncomfortable with vehicles with Auto Start/Stop. The first time I experienced the "feature" it was somewhat disconcerting having the vehicle stop running at a red light. At first, I fought against it. Although I never fully reprogrammed it out of existence, I'd still generally turn it off each time I'd drive the vehicle. The Bronco version of ASS seems to be a little less aggressive than some of my former vehicles. However, there are still little annoyances such as it turning off the engine as I stop in my driveway, only to immediately turn back on as the transmission is shifted to Park.

But why so much vitriol for a "feature" that is pretty benign. Certain consumers seem to hate this capability. Is it because so many of us from the older generations have been taught that starting/stopping the engine is wasteful or even actually damaging to an engine? Or because we are stubborn and don't like being told what to do by new technology that is often perceived to be imposed on us by the "nanny state"?

Clearly, the new technology and engine tolerances make this capability non-destructive in terms of engine wear and tear. It also, on the whole, leads to some incremental MPG gains.

So why do so many of us still feel angst or discomfort with ASS?

At least in my F150, it kills the audio on re-start, which gets very annoying.

I am not a fan of the start/stop but on a positive note,I have to say Mazdas cylinder deactivation is waaayyyy worse, and you can’t disable it even with forscan. I’ve had it in 2 of the 4 CX5s I’ve owned and I feel it every time it turns on or off, especially at slower speeds around 35 mph, it’s horrible. Stupid idea to ruin a good engine.

I know all this crap is a result of overbearing government regs but damn….enough already.

Propaganda like these profits of doom who push the climate agenda.

Worlds fine before we came around and will be fine after all of us are long dead, no need for these extreme measures or to believe the scientists who receive their funding from the govt

Because it is annoying, damaging to an engine and potentially dangerous. For the literal drops of fuel that it saves its just not worth it and by the way last I tracked this, these are OUR vehicles and we should be "allowed" to operate them how we want to and not having "ASS" is how I would prefer to operate MY vehicle. Now if the auto Mfg or the gubberement would care to compensate me (us) handsomely, I am thinking $5.00 per mile ) I may be inclined to let the thing work as designed. The inconvenience on hot days to have A/C stop working, the potential of the vehicle not starting (never any problems with batteries these days is there??) or shutting off in a potential hazardous situation (off roading and on a hill, etc) is short sighted. By the way keep in mind old school or not, an engine goes into what is called "Heat Soak" when it is turned off. Coolant is stopped and the engine is deprived of any cooling and starts to increase internal temperatures. Heat is an enemy of an internal combustion engine, repeat this process hundreds/thousands of times and it will take its toll. To make these systems work "correctly" vehicle Cooling Systems need to be redesigned with electric water pumps that would allow cooling to continue during "ASS" events AND A/C Compressors would need to be electric motor actuated as well. This would mitigate these issues at the cost of more complexity and larger batteries needing to be installed. 'ASS" is a crappy solution that has extremely little impact on fuel mileage and carbon emissions.
