Disabling Auto Start Stop permanently?

[LouG]

When I get exhausted turning off stop/start and lane assist I use custom mode and that reduces my workload to just one button.
Phew!

Best workaround is the custom mode, set it there to no auto start top. Press the top Mode button on steering wheel twice at start up, it will cycle to the custom mode and you're done

Not saying this is wrong. Just "LOL"ing that the workaround to pushing a button once every time you start your car is to push a button TWICE every time you start your car.

(Yes, you may very likely do this anyway, to enact other custom setups).

I'm still super-happy with my 4D Tech Auto Stop/Start Eliminator. Never worry about it again.

Been driving since the mid 1980's. We had to put starters in cars all the time back in the day because they were crappy POS starters.

AS/S has been prolific in the US for about the past dozen years or so. During this time, I can honestly say that I don't personally know anyone who has had to replace a starter that the dealer or shop blamed it on AS/S. In fact, I can't recall the last time I knew someone who had to have a starter replaced. Not one.

Yes because cutting oil flow to a hot engine repeatedly over the lifetime of your car won't have any wear on cams, valves, bearings, etc. Lots of modern engines are chewing up rockers, cams, rod bearings prematurely due to low viscosity oil, auto stop start, things designed to reduce emissions and improve fuel economy. But in reality just kill your engine prematurely.

I have read that auto manufacturers are going to do away with the auto stop feature, since regulations have relaxed a bit, and consensus is that it’s a stupid feature that does next to nothing but irritate the driver.

It MAY be possible that a future over-the air update could possibly make Auto-Stop have the ability to be permanently disabled??? Would be nice!

Just wishful thinking….

Stop/start can actually be dangerous.
My wife's last car had some turbo lag off idle, DSG programmed to get into second gear as soon as you get rolling, which accentuated the lag, and adding stop/start to that was lethal trying to take gap in roundabout traffic.
We could turn off stop/start easily enough, but it was still dodgy in a city full of randabouts.

If it's only about AS/S, just use your middle finger for the ASS-button and your index finger for the engine start button at the same time and your done.
Ford was so nice to not have to wait until engine is running or any software finished booting

I 2rd using the custom settings. Normal mode for less aggressive shifting, track exhaust to piss off my neighbors, track dashboard because it looks awesome, and stupid start stop off with the flick of 1 button.

No evidence to back that up though - just opinion!

Stop/start will cease to be relevant when all ICE cars are hybrids

I like stop start as it saves fuel and emissions when driving in queues - for which there is good evidence. The Ford systems work well compared to some others.

Yes it's totally myopinion, not how ICE are designed to work. Oil pan at bottom. Hot metal bits at top. Turn off motor. Hot metal bits on top have no oil or cooling. Increased friction...

Consequences of Cutting Oil Flow to a Hot Engine (repeatedly):
Repeatedly interrupting cutting oil flow to a hot engine can lead to serious damage and premature engine failure due to:
1. Increased Friction and Wear:
Loss of Lubrication: Engine oil creates a protective film between moving parts like pistons, camshafts, and bearings, reducing friction and preventing wear. Cutting oil flow interruptions compromise this lubrication, leading to metal-to-metal contact.
Accelerated Wear and Tear: Increased friction causes components to wear out faster than normal, leading to loss of compression, reduced performance, and costly repairs.
2. Overheating and Thermal Damage:
Insufficient Cooling: Engine oil absorbs and dissipates heat generated by combustion and friction. Interruptions in oil flow reduce its cooling capacity, causing engine temperature to rise, increasing the risk of thermal damage.
Component Damage: Overheating can cause components to warp, crack, or fail. For example, head gaskets can blow, cylinder heads can warp or crack, and pistons can seize within cylinders.
3. Contamination and Sludge Formation:
Reduced Cleaning: Oil carries contaminants (soot, carbon, metal particles) to the oil filter. Low oil levels compromise this cleaning function, leading to contaminant buildup.
Sludge Formation: Contaminants can lead to the formation of sludge, a thick substance that restricts oil flow, reduces lubrication, and causes overheating.
4. Risk of Engine Seizure and Failure:
Engine Seizure: In severe cases, excessive heat and lack of lubrication can cause the engine's internal components to expand and seize, preventing it from turning over. learn more about Oil Starvation in Car Engines and How Can You Prevent It? on CarHub.
Total Engine Failure: A seized engine typically requires a costly rebuild or replacement. Loss of oil circulation due to pump failure, broken timing chains, or worn bearings can also lead to engine failure.
In summary, repeatedly cutting oil flow to a hot engine creates a detrimental environment where friction, overheating, and contamination damage components and can eventually lead to engine seizure and failure.

You do know engine design and bearing technology has moved on and that S/S systems have been in use for 25+ years with no ill effects. Copy and paste of an article on engine oil starvation isn't evidence of S/S systems failings. So it is exactly how modern engines are designed to work!

Also consider Toyota have been making hybrids for 30 years and have the most reliable engines in the world - many many Prius cars have 400k miles on them on the same engine and battery, they are regularly used as taxi cabs globally.

There is far more detailed evidence available with a simple search but here are a few summaries:

Yes it's all unicorns and rainbows if you hear some EPA goober spin it. Or some auto manufacturers who don't care if your engine blows up outside of the warranty period. In fact they stand to profit from it.

But that isn't how engines work. And some manufactures are finding that out under the warranty period.

Q: What are some issues related to engine wear?

A: Consider the crankshaft: It’s supported by precision-ground journals along its length running in ‘plain’ main bearings (meaning there are no ball bearings or rollers, just smooth metal). The part of the crankshaft at the back of the engine, immediately adjacent to the starter motor, endures the highest loading.

Q: How does stop/start operation change that situation?

A: When the engine is running, the crankshaft and main bearing surfaces don’t actually touch, but are separated by a super-thin film of oil which fed under pressure (called ‘hydrodynamic lubrication’) and pumped throughout the bearing surfaces by the spinning crankshaft. However, when the engine stops, the crank settles onto the bearing with the two metal surfaces coming into contact. Then when the engine is started, there’s a short period before the two surfaces become separated by that oil film (a situation called the ‘boundary condition’) where the crankshaft is spinning, but there’s direct metal-to-metal contact between the bearing surfaces. This is when most wear takes place and having so many stop/start cycles can lead to early failure.

Yes, because some Youtuber says it is true it must be

Evidence - which car makers are finding out under warranty claims? Come on - actual facts. You said it, so you must have evidence to back it up surely?

You don't need to rely on EPA if it upsets you so much, stop start is used reliably around the world on millions of cars. In fact modern ISG setups are better for the engine than an old fashioned starter motor, likewise hybrid systems.

The information is easy to find when you look about how engine design and materials have changed on stop start vehicles


Q: How is the negative impact of metal-metal contact overcome?

A: It requires improvements in both materials and lubrication technologies. Bearing manufacturers are developing new materials with greater self-lubricating properties to resist wear on start-up. For example, Federal-Mogul developed a proprietary metal called Irox with a polymer coating containing particles of iron oxide – yes, rust – which in microscopic form is surprisingly slippery. The coefficient of friction of an Irox bearing is 50 percent lower than a conventional aluminum bearing and should last the life of an engine equipped with stop-start. On the lubrication side, the modern engine oil with its complex chemical composition is being improved with even lower-friction, longer-lasting formulations.
Understanding stop/start automobile-engine design, Part 4: Mechanical wear issues - Power Electronic Tips

This is changing what the bearing manufacturers are offering. Manufacturers are leaning more toward wear resistant material than even what aluminum offers. Manufacturers are adding more hard particles to the aluminum (i.e., more silicon) or they are coating the bearings to handle the increased metal-on-metal contact.

Mine worked for the first few weeks and has not functioned since in the last two months. I've even tried to get it to work by toggling it off then back on, and it never works anymore.

Good riddance.
