A few companies are offering a cable/harness extension that defeats the Stop/Start feature so, it isn't required to manually press the button to turn off, what I consider a dangerous feature, after starting the vehicle.

I have added a similar cable/harness to my Alfa Romeo Giulia. I found one from Aliexpress (I found the one for my Giulia on Aliexpress for less than half the price of the cable/harness extensions here in the States. It works flawlessly.)

The one I found for the GV70 on Aliexpress is listed for: 2020-2021 models. The switches on the GV70 were changed for the 2023 model year so, I don't know if the present offering on Aliexpress fits the newer model year car. (Yes, I've left a message with the vendor on Aliexpress. And, it is China and the weekend so, I haven't received a response as to whether their current switch listed below works on the 2023 models year. I suspect I will at some point.)

I am not a fan of sticking in a toothpick, or a piece of plastic in the switch, or even defeating the hood latch to fool the car.
I know I can just push the button to turn it off each time.
For me, it's just so nice not to have to do that.
I know it's a small thing, but as the fellow said, "It's the small things in life that make big differences."


Has anyone found a Stop/Start cable/ harness extension for a reasonable price here in the States?
If you have, could you please share your experiences?
Thanks...
 
The post above lists a company that sells the Stop/Start defeat harness for the GV70.
They confirmed their switch fits the current 2023 GV70 model.
I
During the text, the company stated there aren't many if any GV80s in China.
However, if someone could supply them with the wiring diagram/schematic of the GV80 Stop/Start switch, they would fabric a harness for the GV80 and sell it on Aliexpress along with Stop/Start defeat harnesses for other models.

If a Genesis tech wanted to chime in and PM me a diagram/schematic for the switch, I will forward it.
I'm only trying to help other Genesis owners out.

I have a GV70 and have ordered the Stop/Start defeat harness for my car.
When I receive it, (about three weeks shipping time from China)
I will post pictures in the forum detailing the installation.
 
Looking to update and upgrade your Genesis luxury sport automobile? Look no further than right here in our own forum store - where orders are shipped immediately!
Looking up the ISG info, it appears to be a ground circuit through a resistor. However i cannot find the value of that resistor. If someone has one, you would want to measure the OHMS between the Black and Green/Black wire when the switch is on

My '23 2.0T SP doesn't have that crap. And don't remember the 3.3T SP I briefly owned (before returning it) had it either. Or is it for the GV70? This is a G70 forum, so a little confusing to see that discussion here:unsure:.

Lol yes we are helping the gv80 crew, diagram is for a 2022 GV80. Actually surprised this post hasn't been moved yet. Bless Genesis for not equipping the ISG system on the G70s, at least the 22+ models

You can remove the wiring harness, measure the DC resistance between terminals 5 and 6, while pressing the ISG button. My guess is 10k Ohms for a typical pull-down resistor like that.
 
Moving the project forward for the GV80 guys...
The vendor in China says he needs pictures of the male and female connectors to duplicate those.

Can anyone in the GV80 fold help out the cause by spending a few minutes taking a couple of pictures?
Thanks, @mnboost for the diagram.
There used to be an expression,
"Taking a slow boat from China."

My GV70 harness is on the way.
 
I was so happy when I found out my G70 didn't even have the idle stop thing.
 
It drove me nuts on the Alfa. (And for me, it's a short drive.)

At one point, I had the hood sensor fooled, by not closing it on the last click.
That was better than me looking at a bread tie.
But, in the end, I spent the money to make it go away.

The G70 guys (@mnboost @Volfy ) have been helping and they don't even have the Stop/Start.

Hopefully, a GV80 owner will post some pictures... it's for them.
 
Pretty sure some G70s have ISG. Our 6MT G70 has that ISG option deleted, along with adaptive cruise. Even says that in the Genesis G70 brochure.

Our Stinger, however, has it. A royal PITN to have to remember to click that button every time I turn on the IGN. I just bought a timer relay and will build my own kit to defeat the ISG. I will wire the two leads across the ISG button (terminals 5 and 6 in above pic) into the output side of the relay. I'll have to add a pull-down resistor, of course. Then all I have to do is program the timer to fire a momentary switch about 1 sec after being fed 12VDC from an ignition switched power source. Voila! ISG defeated.

I received my start/stop defeat harness from China. I'm not sure if I mentioned it, but my sister is the main driver, and the stop/start feature doesn't bother her in the least. She actually thinks it's cool. (I can't understand that, but as they say, "It is what it is." I can't imagine the stress the start/stop causes the starter motor and the battery Yeah, I can. Several here on this forum have had low battery concerns, and this feature sure doesn't help. Oh well, it has a good warranty anyway.)

So, now I have the GV70 start/stop defeat harness and she doesn't want me to install it. If anyone out there wants to purchase it from me, I will send it to them and they can see if they like it. No risk. You can pay me after you install it.

I will sell it for $50 dollars, including shipping. You won't have to wait three weeks to have it shipped from China. I will put it in a USPS flat-rate box and you will have it in three or four days. If you are happy with it, you can pay me with Venmo or Zell. I know the company manufactures quality products. I've been driving around for 2 years with a similar harness made for my Alfa from the same company.
Someone will be able to toss out their bread tie.

You make a good offer, I'm sure someone will appreciate.

You mention the added stress on the starter. Than has come up before, but the starter is not the same one that you[ve seen for the past 75 years. If is much beefier and designed to take the added use with the stop/start system.

Genesis already has an AGM battery, the type recommended for this type system.

I'm sure it's one hell of a starter to handle the designated demands.

I was in NYC with my sister in traffic and in an hour's time, it re-started about 40 or more times. Of course, that isn't normal for us, but for some it is.

Over the course of the car's lifetime, the number of times the starting motor engages would be astonishing to my way of thinking.
I'm sure it's designed to handle the number of starts requested of it.

My main objection is the amount of stress on the battery. I think modern cars have so many electronics, the battery, even an AGM battery is put through too much even without the stop/start.

I don't know. The actual start time is rather rapid. Second? But there is load when not running. The alternator has to be able to keep up on a normal basis when running.

Your NYC experience is real, but in my area, much different. A stop at a light can easily be 90 to 120 seconds but only a handful an hour.
 
I agree. The start time is fabulous compared to some cars, and it's very smooth. I just don't like the car shutting down.
It alarms me when it does shut off and makes me uncomfortable sitting in an intersection. That's just me.

Besides the things I've mentioned, and I'm not saying it would, however, the car having to restart might be the split-second difference between getting out of harm's way and not.

I could see a gas mileage benefit if you have 2-minute red lights and they are common. Gas here is $5 bucks for premium.

I guess you can't edit your posts here as you can in other forums. Here is a picture of the START/STOP harness...

So, has anyone found a place to purchase a stop/start defeat cable for the 2023 GV80?
 
The company that made the one in the picture needs photos of the connectors.
They have the wiring diagram/schematic, just no photos of what the connectors look like.

There are few if any GV80s in China for them to look at and make a harness.
That's what they told me, otherwise, they could have one made up for the GV80.
 
I haven’t attempted it yet but does anyone have any idea if it’s a PITA to get to the switch for illustration purposes? I have a 2023 GV80 and am willing to make that happen.
 
$40 delivered from Aliexpress. Came in about 20 days.


If not allowed to post link. just search aliexpress gv70 gv80 car stop canceller.

When it arrives, also search Youtube for very good install videos.

Only thing I would add:
NOTE the orientation of the connector cable when you remove it...you will be replacing it all by "feel" and can avoid some frustration if you note that the flat side faces down when trying to fit the new connector.
I used my selfie camera to take a picture of the back side of dash to finally figure this out.
Other than that, pretty easy install, and it works great. No fuss, no muss.
