Default Engine Auto Start-Stop in vehicles....

Did they just introduce the engine Auto Start-Stop technology in recent new vehicles??? My mother bought a pretty nice Buick SUV last year, I took it out for a ride when she first got the vehicle and was surprised the engine shutdown after coming to complete stop. Apparently this is a new technology to save fuel.

She hates the lag when accelerating from stops, told here there must be a override switch to disengage the feature and had her bring it to the dealer to show her how to turn it off. They told her there is no way and to just hit a button every time you come from a stop. Thought it was stupid and just a Buick thing.

I'm on a trip right now and have a rental car, same feature is in it. Car is a KIA Soul. Thought since it was a budget vehicle that it existed to be for the economy car model. I hit the override button immediate when I get in the vehicle. Just a annoyance to remember to do it every time getting into the vehicle

Then today I was looking at my bro-in-laws brand new fully loaded GMC Denali pickup truck with the 6.2L engine in it, sure enough, that has the auto shut-off to.

Now I can maybe understand having it in a economy vehicle to get better gas mileage but putting it in a full size loaded PU????? I don't think people buying a vehicle with a large V8 are concerned about getting a little better MPG

I bought a new Tacoma back in 2018, it doesn't having this feature.

My mighty Subaru Outback has a setting on the stupid ass iPad look alike "infotainment" screen where this can be disabled.

I wonder how long the starter will last.

It's just a matter of time before someone invents a device that plugs in and overrides this.

It’s been around for a few years. Anything manufacturers can do to squeeze a little more mpg during the EPA non real world test they will do. Search the Internet there should always be a override switch or setting.

My wife’s ‘18 X5 has it, but the override is right next to the start button. Unfortunately you need to press it every time you start the car. Annoying, but far from the most annoying feature on that car.

starters last fine. Unfortunately, as in I the reman business. Many use a dual coil solenoid, where one coil holds the bendix engaged into the flywheel and a second to engage the starter motor. A few other minor design mods (longer brushes for instance) make it easy to make them last. Biggest thing, warm motors crank easy.

Some of them you can trick by lifting some pressure off the brake pedal, but not enough to creep forward.

The engine will start, and then you are good to go when you actually want to move.

We have a 2019 Transit and didn’t even know it was there, as it didn’t happen for the first 2000 miles. When it first happened I thought the car had stalled and there was a problem...

Apparently, some of the systems are disabled when towing a trailer..

I unplugged it from my 2020 F150. It was simple to do.

How much fuel does this really save? My ‘20 Acura has it and although it can be temporarily disabled, it is a stupid annoyance.

It's been around at least 10 years.

It's like the stupid Commiefornia gas cans. Makes some green government turd able to justify their existence but does nothing to help the environment and just adds further annoyance to the taxpayer.

I showed my mom how to turn it off in her new CRV today. After we stopped to visit grandma it was still off when we started the car. Hopefully it'll stay off.

And you can bet the cars didn't get cheaper because of it. Just like tpms.
