My DIY Rivian R1S Dead Pedal Upgrade: 3D Printed and Ready

Last night, when I reached my Rivian truck after work, my iPhone displayed a message. I captured a screenshot to show what happens if you avoid signing back into the app. The Phone as a Key (PAAK) feature still works without logging in again. If you're in an area with poor cell service, don’t try to sign in. Instead, keep using the app and PAAK until you’re somewhere with a good signal and can access your password. The screen’s text explains this, but some users still get confused. This is a quick tip for PAAK users to avoid trouble.

I created a custom extension for the dead pedal, lifting it by about an inch to improve comfort. I started this project some time ago but hit a snag and didn’t complete it until recently, when I figured out a solid way to secure it.

My design is available for 3D printing if you’re interested in making your own. A company called TWRAPS released their own dead pedal extension, which inspired me to finish mine. Their version looks great, and I recommend checking it out.

My 3D-printed design may not work well with all-weather floor mats, but I’m working on an updated version to fit the original Rivian mats better. Keep an eye out for that update.
