I get the idea that it perhaps saves gas and lowers emissions but at what cost?
I often feels is dangerous because there is short perhaps 1 second delay when taking off from a stop. Its unnerving especially when trying to merge into fast traffic or making a left into oncoming traffic.
I also just had an incident yesterday when it nearly didnt restart while waiting at a busy intersection. It took about 3 seconds to finally start. I think my battery was weak so I had it replaced. It now works fine. But imagine if it didnt restart there in the middle of a very busy intersection.
I dont have any proof but I suspect all the auto stops and starts is why my battery didnt last very long. My car is only 2.5 years old.
There is an option to turn it off but you have to do each time to start the car. There is no memory from previous status. So I often forget to turn it off. If car designers simply provided a way to turn it off and keep it off would solve the problem. Apparently some cars do that like the BMWs but not Honda which is what I have.

(18,607 posts)I pulled over and went through the manual and turned it off. This was a few years ago and I don't recall the model but it 'stuck' so I only had to do it one time. I find it annoying plus your other considerations you mentioned.

(146,243 posts)I push the button every time I start the car. That shuts it off. I do not like the delay at traffic signals. I've noticed that people who use that feature often take a couple of second before they get going. that adds up when there's a lot of traffic. I've even missed a green light a few times, due to people not being able to drive on when the light turns green. So I turn mine off each time the car starts.
The reason it's not something you can turn off globally is that manufacturer city mileage estimates are done with that feature enabled. So, it's the default for it to be enabled whenever you start the car.

(15,659 posts)One reason of this feature is to save the environment. We cant even do this small part? No wonder were failing as a collective.
honest.abe
(8,607 posts)Also what about battery disposal? I dont have any proof or stats but I suspect batteries are not lasting as long due to all this auto stopping and starting. So thats also an environmental issue.
Happy Hoosier
(7,206 posts)It could, I suppose, but not dramatically. Besides, lead-acid batteries can and should be recycled.
honest.abe
(8,607 posts)In my daily commute, if I dont turn the thing off, it starts and stops more than 50 times. If I turn it off then maybe I start and stop 5 times.
Also my battery only lasted 2.5 years. In my previous cars (no auto stop) I would get about 5 years.
Happy Hoosier
(7,206 posts)Im sure you know this, but your one experience cannot be extrapolated to a generalized conclusion.
Also its usually draining a battery that really stresses it. Those starts wont seriously deplete the battery, unless the battery is already damaged, and it is recharged quickly by the alternator.
honest.abe
(8,607 posts)However if you are stopping and starting a car engine 10x more than needed then its common sense the battery would be affected along with a number of other parts of engine.
Happy Hoosier
(7,206 posts)To reality is engineering. And I am an engineer. Lead acid batteries are damaged by being too deeply discharged, not repeated relatively shallow discharges. The alternator recharges the battery relatively quickly. The battery can be damaged by storing it not fully charged as well.
honest.abe
(8,607 posts)YOU'RE TAKING TOO MANY SHORT DRIVES.
Cranking the engine takes a tremendous amount of power from your battery, but as mentioned previously, the alternator recharges your battery while the engine runs. If youre frequently going on short drives, though, the alternator might not have enough time to properly recharge your battery between pit stops especially if you have an older battery. In the long run, frequent short trips can shorten your car batterys lifespan.

(146,243 posts)Some people wedge something in at the top of the button to hold it in place. That works, but it's also quite easy to get into the habit of pushing that button whenever you start the car. If you forget, you can do it the first time the engine shuts itself down. Not really a big deal.
I can't imagine that using the starter motor so many times is a recipe for long life for the starter. Maybe the battery, too. Anyhow, I disable the thing every time I drive the car. So does my wife.

(38,300 posts)Before 2000 smog check places actually checked the integrity of emission systems and would stick a sensor into the car's exhaust pipe while it was running.
Now it's all done by computers. The smog check computer asks your car's computer if its emission control systems are all running within specs. If your car's computer says they're not your car doesn't pass. If the smog test technician sees anything sketchy under the hood your car doesn't pass.
Granted, there are a lot of technicians who, like Sergeant Schultz, see nothing, but it would take some sophisticated hacking to make a modern car's computer deceive the smog test computer.
I've only driven cars with the engine stop feature a few times and never in situations where it annoyed me.
The truck I drive is old, so old it requires an old-style smog test. There are only two places left in our city that can do those, all the other smog places have dumped the equipment required to test cars that are more than twenty years old.
I've driven hybrids and sometimes noticed a little hesitation as the gasoline engine is switched in and out but never enough to be alarming. Non-hybrids do that too, especially when an automatic transmission is switching gears.

Heres how to get around it on that car.
Shift down into the L gears, L1-L6. Push the button on the gear shift till you get up to L6. No more auto stop
L6 is D without the auto stop.
This should work for most GM vehicles I would think.

(4,896 posts)Some manufacturers include a battery sensor that monitors battery power, and will prevent the auto start-stop feature if the battery is weak. If your Honda has a battery sensor, it may not be working properly.
Another option is there are ways to "disable" the auto start, but that can get complicated to do and the procedure varies by manufacturer and sometimes model.

(18,467 posts)It seems the majority are:
-I'm looking for a new car but gas is so expensive and I am concerned about how emissions affect climate change
*I have just the thing. This car comes with an auto-stop feature that shuts the engine off while you are stopped and not moving. It will save you gas and cut emissions.
-Great! Is there any downside?
*It can take a second or two to restart at a traffic light, so there is a small inconvenience.
-Nope, how do I turn that feature off?
FYI- I have driven a couple rentals with this feature and I have found that if you ease up slightly on the brake pedal you can activate the restart without disengaging the brakes.

(6,549 posts)Seriously, I had to look it up.
Sounds like a major PITA (for me, anyway) but I'm wondering - can you could get around it by quickly putting the car in park when you're at a red light?
Xavier Breath
(3,593 posts)You can put it in park to stop the cycle as you suggest, but an easier way is to just let off the brake for a second and then reapply the brake. It's smart enough (at least mine is) that it will discontinue once it realizes you're in a situation with frequent braking. Also, increasing the drain on the battery (upping the fan on the a/c, e.g.) while you're stopped will snap it out of it.
The model I wanted came with this particular feature. I didn't seek it out and I wasn't sure I would want it. But, after a test drive I realized I didn't much notice it. The car is quiet anyway, so shutting off and restarting isn't all that noticeable, especially with the radio cranked. At long stops I treat it like a game, trying to see how long I can go without releasing the brake and restarting it. When a light cycle can last two minutes-plus at a large intersection, all that saved gas is adding up.

(50,522 posts)I never did like the idea that you have to sit at stoplights, drive-throughs etc., burning gas and pumping pollutants into the air for no fucking reason. On the VW Tiguan I have, the engine restarts when you start lifting your foot off the brake, so by the time you have the brakes far enough released that the car will move, its running.
My car also has the Adaptive Cruise Control, and this is really nice. There are two fun things that it does.
First, it has a radar in the cars nose - the antenna is behind the logo on the grille - that measures the speed and distance of the car in front of you. If there is one, when you get to a certain distance behind him - you can choose the distance - it slows you down to his speed so you dont run him over. If necessary it will slow you to a halt, like youd need in rush hour traffic. If the car automatically stops, you just tap the gas pedal to resume driving.
The other is it displays the speed setting. You can program the speed you want while stopped, and once you reach 20 mph push the resume button and it takes you to that speed. This may only be available on VWs with the digital cockpit dashboard, but thats in all new VWs. Two years ago it was only in the top trim levels.

(584 posts)> My car also has the Adaptive Cruise Control, and this is really nice. There are two fun things that it does.
Thank you for bringing this up. Tell me if you have experienced anything like my friend describes.
My friend had an auto trip planned from MO to CO. His car breaks down before he leaves so he rents a new one.
The rental has "Adaptive Cruise" or something similar. I don't remember what model auto this was.
He experiments with all the new features on the trip.
His experience with ACC left him with doubts about its safety.
He had set it to follow a certain distance and some max speed. It worked well when he played with on freeways.
On "twisty" roads it worked ok... until on the case where he was "autofollowing" a car and there was a hard turn and the car in front "disappeared" and his car speeded up to resume set speed. He braked with his foot to slow down.
He did not use that feature any more. [Wife insisted and he didn't disagree.]
I didn't have an opportunity to follow up on this like I wanted to. [He is no longer living.]
Anybody have any similar experiences with cars autodriving into danger?
Thanx.
jmowreader
(50,522 posts)One thing I have noticed: you're following X person in the left lane of a four-lane road. X person pulls to the other lane and slows down. Your car will slow down too.

I HATE the stopping and starting on the newer models. Its got to wear on the battery and the starting process. Theres no way it cant. And Im not sure that I believe the fuel efficiency stuff because it uses fuel to start up over and over and over.

ChoppinBroccoli
(3,781 posts)I bought a new car a little while ago that has that feature. I absolutely hated it, mostly because I could envision the toll it must take on the battery. I quickly found out it can't be set to off as a default, but all you have to do to turn it off is hit a button. It was kind of a pain, but now it's just the routine I do as soon as I start it. Start the car, hit the button that turns it off, hit the Audio button (to put the radio on the setting I like), then put it in gear. You get used to it after a while.
Maybe it saves a LITTLE gas while you're idling at a stop (I think this claim is questionable, actually), but as I said before, I can't imagine it's good for the battery to have to start the car that many times in a single trip (and usually with electronics running at the time it starts). In short, I hate the feature.
