In a Mercedes, it’s flawless and works great. I see no reason at all to ever disengage it. I’m not sure why anyone would want to do so unless it is poorly executed in their vehicle.

What’s wrong with saving a little gas? It doesn’t turn the ac off, it doesn’t wear out the starter, so why do we hate it again?

My dad is getting ready to turn in his 2016 S550. Even at 72, the guy puts a ton of miles on a car. He’s somewhere around 250k miles and he’s never had an issue with his starter. He busts at least two rims a year, but’s that’s a different issue.

I reguards to the starter. A part has so many cycles in it then it breaks, quits whatever. The starter has so many cycles in it and starting 16 times a day instead of 4-5 shortens it's life.

My 2018 F150 V8 has start/stop. It also has a gear reduction starter and an AGM battery. In operation it's almost seamlessly smooth. However, I bypass it right after fastening my seatbelt. Under normal starting, there is no load on the engine. In s/s, the engine is in gear when it starts so you load the lower end instantly. Oil pressure comes up but there is a delay each time. Since I plan to keep this truck until I'm too feeble to drive a pickup, I'll burn a little extra fuel rather than add internal wear. If it was a lease I'd just stay in s/s.

Bottom line: your vehicle, you get to pick.

The starter on a car equipped with start stop is not the same as a standard starter and is built to handle the increased number of cycles.

For those of you who own F150s with start/stop there's a device that you can plug into the trailer plug that fools the computer into thinking a trailer is being towed and shuts off the start/stop.

Some people seem to be working awfully hard to find reasons to hate this advancement. I think the opposition is simple. Anything that reduces gas consumption had to be some liberal nanny state conspiracy to destroy the American way of life. I suspect many of these people still have cases of incandescent light bulbs in their closet because they were being banned.

^^^I do. Along with 2 dozen T12 fluorescents. Sometimes a $.50 bulb that gets occasional use trumps the energy savings of a $7 LED. I used CFLs where the made sense, I had 6 of the 120w equivalents lighting the outside of my house all night long. I've switch to LEDs from halogen in the kitchen. Less heat, plus my wife has yet to realize the switch has an off position.

Call people Luddites all you want, but sometimes that new advancement really is a liberal nanny state device. I'd be willing to bet the incremental increase in cost of these start/stop systems is more than the cost of fuel saved.

My wife acts like we own the power company with the lights that are turned on during the day.

My ‘20 Subaru Crosstrek Limited has it. I’m also worried about the starter so I will deactivate when I think about it since it is on at startup.

I’m one of those who turns my engine off at long traffic lights, train crossings and drive-thrus, but the frequent use of the starter still whacks me out. I haven’t had a starter go out on me in over 30 years, but even so, I’m still squeamish on frequent use due to needless wear and tear.

I’m sure that for most vehicles equipped with engine start/stop, there is an info display which shows time engine is stopped with fuel saved. I get 35 mpg anyway, but it is still neato to conserve a little more.

It is still up in the air how much I will use it in the future.

Fact: Stop/start is a direct result of government CAFE regulations. If you support government mandated regulations just come right out and say it.

I’ve found that if I reduce pedal pressure slightly it does not engage...so I either use lighter pedal pressure or I turn it off with the switch. I find it annoying but not that difficult to deal with. I’m not worried about the starter.

I'm a Texan now (39 years) -- it's patriotic to use gas. My newest vehicle is a 2006 and doesn't have such a device. It won't be due for replacement for at least 7 more years.

FYI might work, might not be a good idea depending on how the ECM changes things when in tow mode.

The Test Plug Hack
by Travis Lambert December 01, 2018
While a trailer is attached auto start-stop will not enable. With this hack a trailer light test plug is inserted into the trailer plug, fooling the truck into thinking a trailer is attached.

On the surface, this appears to be a clever solution, but as it turns out, it’s one of the worst solutions. Modern trucks have many advanced towing features that work well while towing. Transmission shift pressures will increase. Fuel-based remaining distance estimates are adjusted for the reduced fuel mileage. Blind spot systems will expand their range to account for the length of the trailer. Rear ultrasonic object detection and cross traffic alert disables so as not to falsely alarm due to the presence of the trailer. Rear-view camera overlays used to visualize the vehicle path are disabled. Advanced trailer anti-sway controls are enabled, which may brake wheels independently to reduce trailer sway.

The list goes on and on for built-in towing optimizations, and each and every one can be a problem if there’s not actually a trailer connected. Please don’t even consider this as a means to disable auto start-stop.

Found this as an option plugs into the diagnostic port..
