I read something about this a few weeks ago, and I think I have that problem. When I press the START button, sometimes nothing happens. I have to press it two or three times to start the car. From what I remember there is a lot of disassembly required.

EDITED: I just found this - start button on 2015 honda fit not working - Google Search

 

Honda knew about the start button issue.

There was a free Honda Dealer fix for this.

If this is happening to you now you may be too late for the Honda Dealer to replace your start button for no charge.

Go to your local Honda Dealer to see if you still qualify to get this fixed for free.

 

Oh, I love these secret repairs. They go back decades. My dealer is trying to figure out how he can charge me just for talking to him. 😁

I'll have to rely on YouTube. The problem with this is that I could be stuck 100 miles from home. This is why all cars should have ignition switches - but that would cost the makers money

 

I had mine replaced a few years ago.

My start button required more and more push starts to start my Fit.

I went to my local Honda Dealer ready to spend hundreds of dollars to fix this.

To my surprise the Honda Service Tech told me there was a recall for all push start buttons to be fixed for free.

Since then my Fit starts after the first push start.

No more second push starts anymore.

 

I never received a recall notice, and no recalls are outstanding on my car. They just replaced the button? I had heard something about arcing and cleaning. I'll look on YouTube. I'll buy a new button.

EDITED: This guy removed the button, removed the back, sprayed WD-40 inside it, and put it back into the dash - under ten minutes. His car, like mine has the little yellow warning key in the display.


EDITED AGAIN: I don't know year that quick repair was for, but the 2015 and the 2020 require a ridiculous amount of disassembly. I guess that's what you call progress.

 

I think recall is the wrong term. For 2015-17 Fits it was an extended warranty of 125,000 miles or 9 years from original date of purchase.
Warranty extension

 

WD-40 is NOT an electronics-friendly product. It evaporates over time, so it's not a good lubricant, or a particularly good metal protectant. There are better alternatives for every application of WD-40, unless you're maintaining your factory-fresh, period-correct Atlas missile.

Having been stuck 70 miles from home with a bad ignition switch, it's not the solution you think it is. If you're worried about electrical problems disabling the car, order one each of the relays in your fuse boxes (a few are unique, most are a single part used in multiple positions), a good replacement fuse kit (Littelfuse, Bussmann, Eaton all come to mind), a replacement Start button (new or from a salvage car), and the item you'll get the most use from (once or twice every 5 or so years): a jump-start box. There's some perfectly good lithium jump-start power banks out there - "Torque Test Channel" has done a few videos testing them.

For tires, an air pump and a plug kit. Learning to plug tires (it's not complicated) will save you a LOT of time and money. Catch it at the right time and you won't even need to remove the wheel.

 

Right! I'm surprised to see so many people using WD-40 as a universal spray. "WD" stands for "water dispersion," and it was designed for rockets - after thirty-nine attempts. I try to use the appropriate chemical for the job. I bought a gallon jug of WD-40 and use a spray bottle for it. That's sooo much cheaper.

"The original WD-40 formula, created in 1953 by Rocket Chemical Company, is a closely guarded trade secret that remains unchanged and unpatented to protect its formula. It was designed for the aerospace industry to displace water and prevent corrosion, notably on the Atlas missile. While the exact recipe is kept in a bank vault, it is fundamentally a blend of petroleum-based lubricants, solvents, and carbon dioxide."

 

Yes, WD-40 is a good anti-rust product and a light weight lubricant but it doesn't have a long life. Other things like fluid film are apparently all around better especially for rust protection.

I was at an airport about 40 years ago and the plane couldn't depart because one passenger's seat wouldn't stay upright and kept falling all the way back, A technician ran on to the plane carrying a can of WD-40 and he quickly stuck the nozzle straw into the seat mechanism and gave it a few squirts. Problem solved, the seat now latched upright OK. I have no doubt that the seat would be marked for maintenance in the not too distant future and the proper lubricant applied because the WD-40 wouldn't last too long.

 

Fluid Film is great. I bought a gallon and a sprayer to do both cars - many years too late.

From my experience watching air crash investigations, "marked for maintenance in the not too distant future" often never arrives. The FAA will recommend or decree that a modification must be made for safety - within three years. Three years pass, and many planes were never modified. Profit over safety.
