I'm looking for some feedback from any 2018 or 2019 Traverse owners regarding the auto stop/start feature that Chevy introduced on these models. I was all set to buy a new 2018 Traverse last year when the new model was released until I started reading about this feature that was added beginning with the 2018 model. You don't have the option to turn off the auto stop/start like some other vehicles that I've read about so this caused me some concerns about the newer model Traverses. For anyone that has a new model with this feature, have you had any problems or issues with the auto stop/start, such as hesitation, shutter or delay when taking off after the engine starts back up? Or an issue such as the engine falling dead and not starting back up when you come to a stop?

I keep getting this image in my mind of coming to a stop to make a left turn where there is oncoming traffic, and the darn vehicle hesitates or shutters when I try to accelerate or it falls dead all together!

I've read that you can buy some after-market devices to disable the auto stop/start, but of course I'm sure you'd have to be concerned about invalidating the vehicle warranty unless it's that easy to remove this device anytime you take it in for servicing?

Any input would be appreciated. Thanks.

Initially had the same concerns and hated it on my '16 Malibu. Newer one battery DC-DC system on the Traverse works seamlessly. Most of the time I don't even notice it operating. The engine restarts before you can get your foot from the brake to the accelerator..........don't even hear the engine crank for a restart just a slight bump. No hesitation, shutter or delay....engine is up to speed before you hit the accelerator and transmission servos are pressurized during the stop cycle so no delay in tranny engagement.



Easy to disable from the shift lever, shift to L and hit the (+) button eight times for L9 and transmission will automatically upshift and downshift through all the gears for the entire drive cycle same as if a disable button was used.


Aftermarket device will invalidate the warranty, but also requires a different remote starting procedure whose timing and waiting I found unsuitable for my non witnessed starts.

I also had some reservations about the stop/start feature before purchasing my Traverse, but honestly, it is a non-issue. I have to really be paying attention to even notice it taking place. If it's super cold outside, it doesn't auto-stop anyway. By super cold, I mean single digits without the windchill. Which makes right now super duper cold I guess since it is -23 outside today (-46 wind chill).

Anyway... I don't think you will really find it to be a concern. Like Thomcat says above, you can disable it. But why? It's truly not something noticeable when you're operating the vehicle.

FYI Repost of GM info on operation and conditions for start/stop to engage ......


Traverse uses the DC-DC Invertor system which might answer questions relative to why no disable button, which appears to be installed only on Caddys with this system and on the Ultra Capacitor systems.

You can also control it with the brake pedal.

When the engine stops, lift your foot slightly off the brake, then put it back.

It will stay running.

I've had my 2019 traverse since 30 Nov 2018 and about 2400 miles now. I was hesitant with the auto stop feature after experiencing it in a rented Malibu. But really it's not that bad. You will learn very quickly when to expect it to stop. And if I don't want it to, like at a stop sign, then I just feather the brake. I honestly think it is increasing gas mileage. Mine is averaging 22-23 right now, which is incredible for this type of vehicle and engine, and I don't sit in heavy traffic much.

I bought a 2018 Traverse in September ‘17 and didn’t mind the auto stop at first. Now it jerks me to a stop, cuts out when I’m beginning to parallel park, which it just started doing. I feel as if it stops way too much as my father has a traverse and his doesn’t cut off nearly as much. Might have to take it in to get checked. Hopefully I don’t get the “we can’t do anything about it if there is no check engine light on” line...

My wife and I bought a used 2018 Premier Redline. We have had 2 instances where it did NOT start back up. My wife was stuck each time in an intersection. My 11 month old daughter was in the car with her both times. She is not a fan of this feature at all. Two different times after that, the car was parked, the wife came back and the care would not start at all. It has been at the dealer for over a week. They can't replicate it, so they can't fix it. We bought it with 39K miles. We have only put about 1200 on the car since purchase.

Have they changed the battery ? That's step one, dealers do not like to replace parts when it comes out the their pocket as on a used car sale that they can't charge back GM.
I've been the victim of 3 batteries in the last 10 yrs. that had internal connector failures which caused no starts in 2 different vehicles. They all would pass load tests also, in fact smacking the battery or slamming the hood would reconnect the battery, and fail incidents were erratic.

They did not change the battery. They won't do anything until they replicate the problem. My co-worker was doing some searching on the internet after I mentioned they had programmed a new key fob for us after we bought the car. It was used, so it originally only had one. Per the car, it was Key Fob Number 2. When they programmed a second one for us, it ended up being Key Fob Number 3. He found a blurb on the internet somewhere saying that the Key Fob might be the issue. I called the dealer and asked them to wipe those 2 keys then reprogram them both at the same time. We decided to take a gamble and picked up the car after they completed that. we have been driving it for a week. So far, so good.

I just recently bought a 2020 traverse, and it was preowned. I do not think the auto stop is turned on, and I want to know how to do it. Any ideas?? I know many hate it, but I want to know how to turn it on and off and make my own de ton the subject. Thank you!

There is no turn off/on function from the factory. Unless the previous owner had the computer reflashed or had installed some sort of eliminator that is the only way it would be off. Dealer could reflash the computer at your expensive cost and it would only be on full time with no way for you to control it. I spent $180 to eliminate it in mine and it's been money well spent as my Traverse is my 2nd vehicle with auto stop and there is no change in fuel mileage with or without in either one of the 2 vehicles.

You had it disabled on your 2020 Traverse? Was it done thru the a GM dealership or a local mechanic? Thanks!!
