New EPA Rules - Kill the AutoStartStop

Stop/start doesn’t work as well as it should because the battery isn’t big enough to carry functions long enough in engine off situations and results in more shocks to auto transmissions ( pumps don’t keep systems pressurised)

I don't have an issue with having the feature, though mine basically doesn't function anymore, even though my car turns over just fine.  I'm sure once I get a new battery it'll work better again, but still.

 

I feel like they could just give a "perma-off" function for people that don't like it, and let people that are ok with it use it.

I don't see why not. there are ~13 parameters any one of which will prevent ASS from stopping the engine. Trailer-Tow Mode engaged, Battery below threshold, Steering angle past a certain degree and 10 or so more like that. It shouldn't be a problem to do an OAT to turn it off permanently, and I think Ford should to save potential warranty costs from premature starter or battery failures.

There is a system option to turn it on or off.  Today it resets to On.  All they have to do is change it so it doesn't reset.

 

However I doubt they would do that.

Yes, just make the last push of the button stick. Then everyone can be happy.

There are three ways traffic signals work. A) Timer mode, B) Loop sensor (under the asphalt) mode, C) Camera detection. With intersections I'm familiar with. I can with 95% accuracy tell when a signal is going to turn red and when it will turn green. There are sometimes variations, but with practice, you can figure it out.

     Timer controlled: Usually signals will offer a green light to the major artery for 30 to 60 seconds depending on how they programmed it, while offering a green light to the intersecting or minor artery for 10 seconds. If I come across a low-volume side street getting more than 10 seconds, I notify the DOT or municipality and they fix it. Once you figure it out, you can time yourself so that you don't have to come to a dead stop.  Brake wear is greater bringing a 3000 lb. vehicle to a DEAD stop, rather than a slow roll. So by the time I get to the light, it turns green. 

     Loop sensor mode and Camera detection: Both operate by detecting the presence and absence of vehicles approaching on both roadways. The main artery will get priority so you don't have to race up to a red light and jam on your brakes on the major artery. After all or most of the minor artery traffic has passed through, the major artery will get the green. Now if you're on the side street or minor artery, you do need to pull all the way up so the sensors detect your presence IF you're the FIRST approaching. But if somebody ahead of you has triggered the system, you do NOT have to race up to the light. Just back off the gas slightly, tap your brakes if necessary and by the time you get up to the car in front of you, the light will turn green. With practice you'll figure this all out. So who needs START/STOP?

     Camera detection is better at detecting low-mass vehicles such motorcycles and maybe some very small cars. Many signals are programmed so if the major artery detects a huge absence, it will default to red and offer a green light to the side street/minor artery even if there are no cars on the side street!

    What does this all mean? I've gotten 100K to 150K on a set of brakes. Furthermore, I don't floor it at green and have to get up to speed in 500 feet. I take a half a mile. That's why if the mfr. says I should get 25 MPG on average, I get 31.

I agree. They won’t even fix the fog light defaulting off after each restart since moving to digital light functions. I doubt they’ll change a parameter that interfaces with the powertrain OTA.

My '23 F-150 was built during the chip shortage era so it never had the stop/start BS. I'm not complaining. The '18 F-150 I had before that had a malfunctioning stop/start issue. It would shut the engine off while still moving but that only ever happened a couple of times while in Tow/Haul mode which really sucked. It quit working altogether eventually. That truck was also hard on batteries so I wonder if the system is smart enough to sense when the battery and/or starter motor is weak?

An under-performing battery will disable the Auto S/S system. My 2023 Explorer Timberline also had the A/Start-Stop system deleted due to a chip shortage, the window sticker showed a $40 credit due to it's removal.

That's the number one reason it gets disabled.  Even with a good battery it turns it off after 2-3 times in a row close together.
