I notice there's not too many (none) senior enthusiast posters jumping to stuff this in their $50K toy. Been around too long to trust a fairly new gizmo designed to fool a complex system.in my toy.

Here's my .02 worth of opinion:

Easier to hit the stupid button every now and then than to disable s/s by giving Humpty Dumpty a console-ectomy. Only takes 15 mins to install the gizmo and that's exactly how long it takes to void the electrical warranty and possibly the starter motor and transmission warranty. Once a dealer detects installation of an aftermarket electrical gizmo you're warranty is SOL.

Ever occur that although you can do something, but maybe you shouldn't? Maybe not such a good idea to permanently defeat the system unless you know how it affects other systems in the long term. Not familiar with the s/s operation and the Silvy 8 speed, but plenty of info out there on s/s operation on transverse tranny setups with GM 6, 8 and 9 speeds. Defeat systems gizmos for the Traverse are a quickie 1 minute install/remove under the hood and involve modification of the remote start procedure. But they can be removed without a time consuming revision console-ectomy and thus no longer detectable when brought to the dealer for service, because when detected it is grounds for the dealer voiding the electrical warranty, and maybe other systems which are flexed on remote restart. A permanent defeat type system does not flex any of the normally cycling s/s components, i.e. split starter solenoid engagement of the flywheel, pressure servo in the tranny, etc.. Might be worth a little more research and guinea pig usage before wiring a non OEM gizmo into a $50K toy that you hope to keep under warranty

Some background info on s/s systems, some GM pubs:

My main reason for not sticking one in my Traverse, which lacks a simple defeat switch, concerns long term effects on the tranny. When the motor is stopped so are the pressure generating pump and servos in the tranny designed to apply pressure to the bands during an auto stop cycle. Absent constant pressure results in a delayed restart and possible band slippage upon waking from an autostop cycle. To prevent this a hydraulic servo is recharged while the engine is running and the pressure maintained on the tranny's bands fed during the stop cycle for a seamless start and takeoff.

The question I asked myself is: What will happen to the condition of the servos and hydraulic activators designed for millions of cycles if they remained idle for months, years? Likewise the ability of the forward end of the split solenoid to disengage after years of idle attachment to the rear half. Not good when mechanical/hydraulic automotive components remain idle for a long period.

Can't exactly say years of research went into a gizmo designed for a 2019 GM product. I've decided it's easier to push a button for now and let others act as guinea pigs. Looking forward to users re-posts in a few years.

Well said Thomcat and I agree with you 100% it doesn't brother me at all to hit the button when I start the truck, why spend the money on something when you can do it for free and it only takes about 2 seconds.

Funny thomcat you have the same vehicle line-up I have in my driveway.

This statement makes no sense.... GM would have never designed a bypass if it would damage the servo's etc.

What would happen if for the next year or two every time I get in my truck and start it, I press the bypass button before I take off?

Certainly they must have thought of that.

My opinion is all these gas savings tricks are B.S. and only cost the consumer money when the fail. I will continue to buy vehicles that don’t have them. Start-Stop, cylinder deactivation not having them.

Well, not trying be argumentative, but I'm already getting better fuel mileage than I ever did with my 07 Classic. Only my 2nd tank revealed almost 21 mpg. Plus, it runs so dam good.

I love this new 5.3 /However, I always disable the start/stop feature. I really dont care for that.

A non sequitur. Existence of a bypass button is irrelevant to the subject. And GM engineers certainly did not envision or plan for someone gutting Humpty Dumpty and planting a gizmo in his guts..

Every time you start the truck the s/s default is ON not off...so maybe it cycles the system and flexes the servos on startup before the button is active and the gizmo prevents that.....and maybe it doesn't......but one thing is for certain neither of us know for certain whether it does or not.

But one thing is certain, there is a good reason why you don't f%#@ with a system under warranty. So, pray you don't breakdown on the side of the road and get towed to the nearest GM dealer with an electrical/ECU/BCU problem. If the dealer upon testing discovers an unknown gizmo in the system, whether or not it actually caused a problem, he has grounds and the power to void your warranty and costs for the repair is on you. Plenty of guidance from GM to dealers on this matter......advised the first thing the check for is a foreign electrical component in the system

That's the same argument I made against seat belts in '63 and airbags in '95. And whether or not these B.S.gimmicks actually save gas is irrelevant what matters is what tax incentives the manufacturer gets for putting the crap on to claim they meet CAFE standards and fleet mileages. And it will only get worse.

If planning to buy a new vehicle in the future that doesn't have any of this......next truck may be a '00 Silverado.

I’m aware. My forever truck is 92 Chevy. I will refresh as needed. My daily is a Camry. I’d rather drive a impala. For the stated reasons I don’t.

A Silverado, A Traverse and A Malibu...........found it to be the perfect GM lineup for my needs........A Donkey, A Taxi and A combo grocery-getter / visitor scooter.

KARNUT · July 27, 2019

My sons Malibu had one of two batteries fail. Two because of the start-stop feature. 400$, defeats whatever gas savings he may have gotten. I believe his car was two years old at the time. Wonder how much the starter cost?

BBrutus, how many times have you thrown your Silverado in the garbage? Do you apply this attitude to everything and everyone in your life? Your bin must be huge.

My '16 Malibu had the old two battery s/s system - primitive crap. The '18 has the refined DC-DC inverter system with the single AGM battery just like the '18 Traverse. seamless starting. Besides on these without a defeat switch, all you have to do is shift to Lx where x is the highest gear and s/s is defeated with full auto operation.

Besides s/s is not to save gas, but to save the planet Earth, same BS. Your complaint belongs with your Congressional reps to ease CAFE standards which encourage these ridiculous systems to save gas.

You're overthinking it. All the Eliminator does is turn the A/S/S switch into a toggle switch. It remembers the last position of the switch. Had one in an F150 for a year with no problems.

Thomcat · July 28, 2019

I overthink everything when it comes to possibly screwing up something and end up out of State with a broken down vehicle having a dealer tell me "tough $hit warranty invalid" even if it a technicality that did not effect the electrical failure......and told to prove it

In actuality I'm amazed how well the system works compared to their first try in my '16 Malibu. The V8 starts just as seamlessly as the smaller V6 in my Traverse.

Here's basis for my .02 opinion and pet peeve concerning the issue..........

For two years since buying my '18 Traverse, whiners on the Traverse board have been complaining about the inclusion of a s/s system on their new gen Traverse. Their main complaint relative to s/s was that they wish, they really, really wish, that GM had included a defeat button on the system like on the Cadillac or Honda, yada, yada......and GM was so stupid and inconsiderate for not including one......like reaching to the dash to press a defeat button was so much more trouble than clicking the (+) button which is already on the shift lever 7 times to L8 to defeat the system and would wear out their thumb. And comparatively few complaints about the system being introduced into the new gen vehicle as opposed to no defeat button.

Now that GM has placed a defeat button in the new gen Silverado, resulting in their acquiescing to such customer complaints, now the complaint is get it out altogether or my car, my decision I'll outsmart you by wiring in a gizmo that I personally have no idea how it works or long term effects and do it myself and so all you can do is to invalidate my warranty. People act as if they're upset a s/s system was somehow magically installed into the vehicle after the sale. Mine was there before the test ride, used it during the test ride and bought it anyway and vehicle is still doing everything it was designed to do before the sale. Process is called Caveat Emptor.

My main complaint with the Silverado is that it is somehow grounded, no matter what the speed it can't fly, and no defeat button for taking it airborne either. But, I'll fix GM just as soon as an aftermarket comes out with a non OEM invention to slap a GE90 turbofan into the bed.

KARNUT · July 28, 2019

Put that much thought in cylinder deactivation or how many times the starter engages with stop start. You’ll be driving a Toyota. I have put lots of stock in after market. They usually test on their own rides. One product comes to mind, switching to synthetics in the late 80s. Transmission goes out in an 88 one ton Ford truck at 100K miles. Add Amsoil Synthetic transmission fluid at rebuild. 180K additional miles traded in with no additional rebuilds. Added electric fans back in the day on vehicles with manual fans. ACs worked better, transmission ran cooler. Saying that I wouldn’t add products to eliminate a problem that I could defeat with a few steps offered by the manufacturer.
