Hi everyone! We were fortunate enough to purchase a 2020 Enclave Essence about 1 week ago. I've done a lot of research on disabling the auto start/stop but I have yet to find a solution for the 2020 Enclave. I tried reaching out to both of the 'companies' that have solutions for earlier models:

[email protected]

Both said they do not currently support the 2020 Enclave. I was a bit surprised that this late in 2020 (November) neither solution was updated to support the 2020, so clearly the demand must not be there. However, I want to disable it. I have considered disconnecting the hood latch, but my will will not allow for the 'check engine' light to exist on forever. I am aware of the solution to shift into L, then paddle shift up to gear 9.

Anyone have the technical chops to create a defeat device for the 2020, or does anyone have a solution I was unable to find? Thank you in advance!

I also have a 2020 and thought there were devices available, but chose to go the L9 route. It's quick and simple and works as well as being free. I will look again at the devices as I did not think there was any difference between the 19 & 20 in that regard.

Thanks ibis1 - curious to see if you can find anything else! I've read a lot of posts talking about the disappointing luxury finishes (lack of intermitted wipers, sunshade quality, use of plastics, etc.), but coming from a 2015 Honda Pilot, we are really happy. The ride is great and quiet, the tech stack with carplay, XM, wifi, etc., is all fantastic. And the dealer incentives (going on recently) put these cars in a really strong place with the competition. We're still really happy.

Just curious why you want to disable this feature. It is apparently designed to help save fuel, which I don't think is a bad thing. Of the last 3 cars I have obtained, they all have had this feature. I have not noticed any decrease in function, while I have noticed improvement in gas milage. I guess if you want to peel off the line, you may not like it, but who would do that in an Enclave in the first place?

It's not about peeling off the line or a desire to spend more on fuel. I don't like the driving experience when my car suddenly shuts off and the slight delay when I then press the gas pedal. Further, I do not want the additional wear and tear on the car. There is evidence out there suggesting you can save 3-8% in heavy traffic and that might be your driving condition. I spend little time in heavy traffic, but drive mostly suburban / highway, therefore I have some stop and go, during which points it's nice to have the car on and ready. There are many people that feel the same way about stop/start technology, which is why people create aftermarket solutions.

I wonder how many starters have had to be replaced as a result of that system? If the number is significant then the fuel savings is most likely washed away. Perhaps it does reduce pollution to some small degree but today's cars don't produce that much pollution anyway. :unsure:

For those concerned with premature starter failure in vehicles using stop/start, his was taken into engineering consideration. As a result, the starters utilized are way more heavy duty compared to their predecessors.

I have noticed a difference between manually starting the engine and restarting after a stop. The restart usually seems to be much quieter by comparison, although I don't know how that is set up.

I have a 2020 as well, and am looking for an override/disable device. I've also noticed that none of the 3rd party solution providers have it for the 2020, suggesting to me that it might be different than its predecessors. I'm waiting patiently hoping something will come to market.

Auto start/stop is a joke. It’s only there because the EPA test loop involves a large chunk of time where the cars are idling while stopped so manufacturers saw an opportunity to fudge their numbers. In the real world you not saving anywhere near what the savings got them during this sham of a test.


If you look at the city and AC portions of the EPA test loops you’ll see there is a significant amount of time spent not moving. Manufacturers noticed this too and as the EPA kept mandating higher MPG’s they saw an opportunity to add an auto stop/start system that would give them a nice boost on the test even though it wouldn’t save people almost anything in real world driving. Studies have shown you need to idle for 10 seconds or more for a shutdown/restart to be better than just letting the car idle. Pay attention in traffic to how many times you’re actually stopped that long. Unless you live in one of the handful of cities with terrible traffic chances are the majority of your stops are less than 10 seconds.

Has anyone on this discussion tested to see if the hood override function will disable the stop/start system on their 2020 Enclave? I was going to check this past weekend on mine, but got sidetracked. If that still works, I don't know why the current aftermarket devices would not work on 2020's, unless the connector has changed on the 2020's. If the hood switch will still disable the system, all you need is a small spool of 18ga. wire and a toggle switch to override it. If you want to get fancy, an OEM switch that fits in the infotainment screen surround could probably be used.

I thought someone had and was told it was not, but I checked mine today to see if the hood switch would disable the system and it did. That being said, I don't know why those devices would not work unless the connector has changed. The good side is, a spool of wire, a toggle switch and a few minutes of time will fix the problem for less than $20.00.

I contacted the manufacture and they said the 2019 will NOT work on the 2020 and they don't have a 2020 yet.

I have found that if I don't press the brake pedal too hard that the engine will either stay running or restart, it takes a finer touch. Otherwise love our 2020 Avenir.

I would love to try this but I feel like I'd need a bit more instruction. Heck, put together a kit with some video instructions and sell it to me!

It is really quite simple. All you need to do is open and close the hood switch circuit. Locate the hood switch connector. (It is in plane view to the left of the hood latch with 3 wires) On the switch side the wires are yellow, red and black. On the harness side they are yellow with 2 black. I would tap into the switch side as that can always be replaced as opposed to the harness side. Snip the yellow wire, leaving enough length to work with from the connector. At this point, make sure the hood is closed and get into vehicle and start it. Make sure the instrument display prompts you that the hood is open, if so, drive the vehicle to verify the stop-start system has been disabled. If so, you simply need to install a toggle switch to the yellow wire. One wire to each side of the cut wire. If you need any additional information just ask. Good luck.

buick jay, I should add, once installed, AFTER you turn the vehicle off, flip the switch and AFTER you start the vehicle flip the switch. I should add there is NOT any polarity here. It does NOT matter which wire you connect from the switch to your yellow wire, just connect them.

As others have said, it doesn't save any fuel in real-world driving conditions, it puts thousands more start cycles on your engine than are necessary (I don't care what they say about allegedly stronger starters or better engine design, no mechanical device benefits from being stopped and started more), it disrupts heating or cooling as it switches to battery power depending on conditions, the short pause while the engine restarts is disconcerting during those times when you need to quickly move into traffic, and it's annoying.

I contacted Range Technology about their device and was told there's no difference in the systems, but they just haven't physically tested it yet on the later models and therefore can't guarantee it. I guess you'd have to buy one, try it, and return it if it didn't work.
