I ONCE rented from HERTZ, a Chevy premium size car that had that feature. It stalled completely in the middle of intersections twice and had to be restarted both times while people behind me blew their horns. When I called Hertz about it, the 20-something numb-nuts at HERTZ just said that I didn't know how to drive and it was normal! Did I mention it was HERTZ? I read the owner's manual in the glove box and managed to turn off the failing feature. Hertz would not send a replacement. It was the last time I rented from HERTZ. I flushed their "Gold" card down the toilet.

Wife got a loaner C class with it. We both agreed we disliked it. It wasn't the stop/shut off, it was the obvious starting back up that was "annoying". I found if instead of coming to a complete stop you hung back and left your foot light on the brake or off it the car stayed running. Kind of made it a game to keep it from shutting off constantly.

My car has it. It is a manual trans. If I couldn't disable it, I would sell the car tomorrow. You know what happens when you stall a manual trans vehicle? The instant lack of vibrations and noise makes me think that I somehow did something wrong. No thanks.

My F150 3.5 EB has it. It's sad. I can program the truck to start any time and run for varying times to warm up, but can't "correctly" and permanently disable auto start/stop....so I put the jumper in.

Seems like any new tuners that come out should be able to disable this.

there is more to go wrong, but yet cars are significantly more reliable then 40 year old simple cars. If you want to argue you donít like them because you donít understand or fix them, thatís valid. But donít go down the reliability path.

Big Fun.
Branch heads, B1 cam, Venolia slugs, Bub pipes, fork brace, braided lines, steering damper, really low clamp ons.
Safety wired.
Those thinks had heaters which would melt steel.

My VW Golf R has the start/stop "feature" but it has a button to disable it right next to the "Start" button on the console. Easy to disable. The DSG dual clutch automatics like mine have the start/stop "feature", the 6 speed manuals do not.

Minor annoyance to hit the disable button every time I start the car but not a big deal.

It is disconcerting when the car next to me at a stop light cranks up.

There are more reliable, but it is much more likely they will not last longer. With only a limited supply of replacement parts, those computers, without which the cars will not run, making the cars bricks once the parts are no longer available.

And that's why I bought a muscle car. I want to hear my quad exhaust at the light and have others hear it when I am passing them as they are mindlessly texting about nothing.....

Well they just started the auto-stop-start on the 2017 models. Not enough time has passed to know.
Kinda like saying out brand new models don't have any recalls.

I used to play a variation of that game back in high school on cold days. Seems like the cars I drove back then were in fact ahead of their times.

This is the only reason they're installed. Car companies have to meet mandated CAFE numbers and still sell vehicles people will buy. This feature is designed to get a higher number on the EPA test.

I have it on one of my cars and while I turned it off it really wasn't that big of a deal. The main trick is to lift your off the brake slightly to not have it activate.

Some start/stop technology doesn't use the starter to get the engine going again. That sort of technology makes the drivability much more pleasant. There are abundant postings on the net by folks who shut off their stop/start feature because it is very noticeable and disconcerting. It's basically imperceptible on my Kia Niro, and bro has a 2019 RAM with e-Torque that's very smooth, engine restarts are instantaneous and virtually imperceptible. The Niro is a hybrid, similar to a Prius, so the gas engine shuts down not only when you come to a full stop, but while driving as well. Sometimes at highway speed. You can hear the engine start up sometimes while sitting or driving very slowly. But above 20 mph I pretty much have to look at the indicator on the dash to see if I'm running electric or gas or both.

do you have to disable it every day you drive the car? or does the disable switch "keep" it off?

why do I ask?
The AC in my older Nissan maxima always resets the "ac recirc to outside air when you start it.
Its real hot here in summer and I always want the recirc "on", to use inside air (which will get colder than using outside air.) so every time you restart you have to push the recirc button. Dumb dumb...

It's been around in select applications (Mini, a handful of Ford models, Jag, and a few others). Some going back as far as 2011. Essentially what they do in most cases is use a regular starter with 2 coils in the solenoid, and beef up the solenoid a little bit. In the past the same coil was used to engage the contacts which turns the starter motor, and simultaneously throw out the drive to engage the ring gear. With most start/stop starters, 1 coil does each function. Sitting still, the bendix pre-engages the ring gear, which allows for much faster starting. On units we have torn down they show no signs of frequent cycling contributing to their failure.

Every time you start the car, or every time you cycle the key? Side note regarding your maxima. If you ever notice any oil leaks, get them fixed quick. Will take out your alternator and AC clutch in short order if you don't.
