Disabling Grenadier Stop/Start

EDIT: 20 April 2025

Fitted the item on arrival and probably took one minute at most.


Found this on an American website and consequently ordered it. When I bought the vehicle the Stop/Start didn’t work, which pleased me. When a software update became available I asked that it could be omitted. As expected, the dealer had to do to comply with regulations. This fix will be a permanent and so simple.

THE BUTTON PUSHER (Description from the linked website)

We have a solution to that issue in your Grenadier that has been pushing your buttons….because you constantly have to push this button. 

Machined from 6061 Aluminum and 303 Stainless Steel, and designed to blend in with the factory styling. Custom made by GrenadierUSA. The Button Pusher holds in the Automatic Start/Stop or Park Assist Bypass buttons so you can drive in peace without having to press these button every time you turn on your truck. 

Installation is simple, just remove the lower inboard trim screw and replace it with our assembly. An internal spring is set to deliver just enough force to lightly hold down your Auto Start Stop (ASS) button. If the button is held down when you turn on your Grenadier, the result is that the ASS function is turned off. Automatically. Every time you start the vehicle. So no more sudden engine shut downs at inopportune times. 

The same Button Pusher can also be used on the Park Assist button. By engaging the button pusher on the Park Assist you automatically turn off the parking sensors upon starting the vehicle. This is a great option if you use a bike rack or have other gear/issues with your bumper mounted ultrasonic sensors. 

PLEASE NOTE: OVER A 5 MONTH TESTING PERIOD, THERE HAVE BEEN NO ERROR CODES OR ADVERSE ISSUES RESULTING FROM USING THE BUTTON PUSHER FOR THE AUTO START STOP. WHEN USING THIS BUTTON PUSHER WITH THE PARK ASSIST YOU WE SEE AN ALARM FOR “PDC ERROR” AND YOU WILL ALSO SEE THE FRONT AND REAR SENSORS ARE TURNED OFF.  WE ASSUME NO RESPONSIBILITY FOR HOW THIS OR ANY OTHER AFTERMARKET PART MAY AFFECT YOUR VEHICLE OR ITS WARRANTY. 

Colors currently available are Black, Silver, and Red. The black is the most subtle of the colors and blends very well with the existing black square buttons. If you want this product to disappear, black is the best choice. Silver stands out a bit more than black and is a great choice is you want this part to be noticeable but still look like is blends in seamlessly with the factory styling. And is you want a pop of color, red is the best choice. 

*Please note that anodizing is done in lots, so there can be minor variations in color from lot to lot.

**These are sold individually. You can choose to order one if you only want to bypass the Auto Start/Stop. If you want to also turn off your Park assist you would need to order two
