Revealing The Truth About Auto Start Stop: 3 Myths Busted!

I found a really easy free way to disable auto start stop on a 2023 F150 without doing anything thar would void your warranty or damage your vehicle in any way. On your infotainment system, go into features, then tap on towing, tap on select active trailer. Select default trailer. Done. Doesn't effect the backup camera at all. You're welcome. Im going to post my own video so everyone knows.

More crap to screw up. Need a extra battery, beats the crap out of the ring gear and starter.
Foolish idea .

Please explain why Acura modified the start stop on the MDX to take longer to start. The reason Acura did this was due to the increased failure rate of the starter ???? Any maintenance engineer will tell you that the highest wear occurs on startup.

it absolutely over uses your starter, All the other issues he may have a point, but the Starter is most definitely over used, and with Manufacturers economically engineering these new vehicles do you believe that they have compensated for all the starts and stops and enlarged the started to match it??? the answer is clear = NO!

Look there is nothing worse than a half truth and that's what you are doing here . The 3-10% increase in fuel economy only applies to specific conditions like between 40-75 degrees ambient temp. If you are running the AC you could only maybe get 1-3% fuel savings. Now for the elephant in the room! First I am an electrical engineer BSEE . You will damage your engine with continuous starting and stopping of the engine. The Start/Stop technology was not designed for ICE engines it was for Hybrids and EVS The EPA put mandates on these vehicles for better emissions. They don't give two Shits about your fuel economy they are more concerned about emissions

That's why they have the engine shut off at idle. ICE engines are typically designed for somewhere around 100k start/stop cycles. Incorporating Start stop tech into ICE engines means more stress on the engine bearings surfaces also more start stop cycles not to mention car batteries are not designed for constant cranking you would need a deep cycle battery for that. To put a fine point on it. It was auto makers attempt to comply with the EPA and CAFE standards. That one little switch if it wasn't there would cost auto makers huge fines for not meeting the EPA CAFE standards.

What I like to know is, doesn't the start stop feature cause engine to wear out faster due to no lubrication when it started back up each time? You know ...when the engine stop doesn't all the oil lubrication dropped down instead of keeping the metal lubricate. Has there been any thorough test to see if it will cause the engine to wear out each time it restarts back up?

I hate the start stop on my Chevy Cruze. I've almost been t-boned twice cause the power wasn't there at all when I tried to accelerate pull out of a road or parking lot. And yes there was plenty of room for me to go when o git the gas, the car just didn't go when I wanted it to because of this feature

Start stop is great for coking your turbos and wearing out starters… 😂

Any engine is stressed the most when starting and stopping. The engine speed goes from operating to zero and conversely during start stop. This puts stress on all rotating components. The fact that start/stop is activated makes everything endure 10x more punch than previously.

The fact that everything is built more reliably should, likely make the engine more robust if you disable start/stop... :)

First thing I do is turn that thing off. Nope I don't want my pinion getting beat up and I drove so far down the road that I really don't come to a full stop very often. Jack rabbit starts and racing between signals is what kills vehicles. My vehicle doesn't have a turbo just one more thing to break.

If you think the AAA is providing the full and accurate data, I have a bridge in Brooklyn to sell you.

Very informative video. On a half ton pickup, 7% better mileage is about 1.5 miles per gallon. Just trust that the automakers are using better parts for stop start. I will stick with my 2007 Saturn with a manual transmission thank you. If my engine ever stops, just give it a push, pop the cluctch. Start! LOL

For me the bigger question is "what is the real value of using these systems?" Manufacturers will tell you fuel economy which, as you described, is marginally true but that's not why they're in the vehicles. Manufacturers don't really care about your fuel savings but they do care about EPA ratings. Including these systems helps them in this area, which is likely why they are including them. Also, and more importantly, peoples driving habits are by far more responsible for poor fuel economy than any other single factor.

My car allows me to disable this function at every start and I always do. I appreciate your perspective but, logically, parts that cycle more will require replacement sooner. I can buy more gas but would rather not buy engine components.

You did not talk about rare on the starter

And we all know: Auto and Oil companies never lie.
:)
The whole thing is silly. Just keep the engine running.

Thanks for this mr. beardy guy. It's cleared up a few things I've been worrying about.

As soon as I drove my new F150 it was apparent it is a nuisance. I installed a bypass module. Best thing I ever did for the auto stop/start.

Friction bearings that have journals like mains and big ends ride up on the oil film like a skimboard on a beach and because when you stop the wedge( the wall of oil) in front of the bearing ceases to exist you are drastically damaging the engine every start, more so than thousands of miles of usage I guarantee that engines left with stop start on will do thousands of miles less than those that deactivate this rubbish every time they start their cars. ( 40 years as a mechanic and qualified mechanical engineer)

I know the starter will go out 10 times faster than a vehicle doesn’t have that crap.

auto-scam.

Saves 5-7% ?
No matter, it is annoying.

Depending in what city on how much gas you wait. Start stop is very hard on the strarter.

Myth or not. I have a manual transmission VW that has about
350 000km trouble free, fitted with start stop technology, I however do not use this start stop period. I am still not convicted that my starter, battery and other engine components will do good, although build to be handle this beating. I am not prepared to tempt fate. Manufactures build cars to last to more or less the warranty period, if you intend to keep the car for longer duration, you then need to take precautionary measures, I do not think this start stop technology is intended for longevity.

Your Stupid. Battery , Starter, Altenator are taking a beating how much did you get paid for this bull Stt

Interesting conversation. My concern would be a hot spinning turbo going dry for those moments until it spools down .

save $50 on gas and spend $900 on liquid filled motor mount replacement.. Next to cylinder deactivation, this is absolutely the 2nd stupidest idea ever conceived.. That 1 second delay is more irritating than the bums who try to wash my windshield at stop lights...

I am not a mechanic.........but logic tells you if you are doing dozens and dozens of extra start and stop cycles per week.........it has to cause damage to the engine and starter and battery. Come on it is a ridiculous idea and saves tiny amounts of fuel. Also the cars with large displacement engines have to use heavy heavy duty batteries. My next door neighbor has this feature and he had to buy a 350 dollar battery.

I sore a Scotsman kilmore video now I confuséd

So bottom line, yes it's harder on the engine but the engine is built to take it. So, if it's disabled, the engine will even last LONGER because it's not being beaten upon. I have to admit, I'm going to use Forscan to disable it simply because I don't like being told what to do by enviro-whackos.

Atlanta is one of those places where drivers are incredibly hostile and aggressive. The last thing I need is to stop at an intersection and need to go in a hurry and my engine stops. That delay is going to get me killed one day.

I always figured it was just a way to make more money from starters wearing out more frequently than other vehicles without start/stop

There's still another point to all of this even though the starter in the turbos and whatever else maybe built with higher quality materials and design to withstand the constant starting and shutting off in all reality if you were to disable the auto stop start feature permanently these same parts would last twice as long than if you left AutoStart feature on for the life of your car. Therefore auto stop start is still contributing to extra wear that isn't necessary. Unless you are willing to exchange that wear for a 5 percent difference in gas mileage. I personally am not willing to exchange that and there are plenty of aftermarket modules that you can buy that just plug directly in and permanently disable the auto stop start so you don't have to push the button every time you get in your car and start the engine.

Yeah the fords probably can’t handle it.
Buy a Toyota.

Any engineer(not working for the auto industry) knows that starting and stopping rotating machinery , e.g., a car engine, for one, leads to premature failure. The [engine's] attached oil pump only provides lubrication when the engine is running. It does not provide full oil flow instantly when the engine is started. A Start/Stop engine feature is a good way to sell more vehicles.

Theres an SAE paper assesses start/stop as worthless if you dont stop for 2 minutes.

I can't fix that car in my home garage so its crap

I live in Alberta Canada where temps reach -35 degrees, when you push the stop start with the brake on and it doesn’t start make sure you keep your foot on the brake before trying again, if you take it off, the booster, being already pumped up won’t push down far enough to allow a second start.

Why are we mandated by the EPA to have to manually turn it off every time the care is started ? It's dangerous when I'm trying to turn at an intersection and I need the car to respond quickly so the oncomming car doesn't hit me. Do you really want the engine to be turned off while trying to beat the traffic at the turn?
So I found a car, a Lexus RX 350 that allows you to modulate the auto stop/start with the brake pedal, based on how much pressure you apply to the brake pedal. My prayers have been answered. Now I don't have to remember to hit the stupid switch and have that glaring yellow light on the dash.

Excellent

Well if you have the system and you get it disabled in some way then your starter should last 100 times longer then if it didn’t have the system, the small amount of fuel savings isn’t worth the annoyance of said system, thank god for Auto Stop Eliminator 🤗🤗🤗

Saw a report that 2017 and 2018 Ford Edge are having problems with Flywheel ring gear cracking, very expensive to fix. Start/Stop systems are so car makers can get better results in the EPA city driving portion of the test. In real world driving they are a pain as they do not turn the engine back on fast enough and I have people honking at me. I just do not like them. With the flywheel problems I am glad I disabled my Start / Stop system for good, a year ago on my 2020 Ford Edge. Good to know that my starter will last years longer because I am not using Start / Stop and do not have to remember to push an extra button each time I start the car.

2016 escape . Lot of draw on battery. I turn mine off. 😊

Let’s see how long these starters last over time after being “beat on” for years. The worst part is the sheer annoyance these systems are, including turning off only to turn right back on in milliseconds, and doing so in scorching heat.

It's a Ford, it will die well before the start/stop takes it out. 🤣 Recent stuff from Ford is ridiculous. Like a wet timing belt. Like really Ford? Really?

You don’t need to worry about start/stop damaging the engine.
Its a ford, give it time and it will damage itself eventually.

I recently got a 2018 equinox 2.0. Didn’t realize how annoying the start stop was and of course being GM you can’t turn it off without some pigtail/bypass or driving in Low maxed out, all the time which is equally annoying

The plan is First make cars expensive crappy and complicated then get rid of them altogether.

Good Job! Maybe you can dispel the miths about the covid 19 vaccines next. And the GM cylinder defecation systems

It’s enough to damage the starter
