Turbo Vado SL 2 6.0 - turns itself on when off and unattended

[John in CA]

My Specialized Turbo Vado SL 2 6.0 randomly turns itself on--Mastermind H3 display, headlight and taillight. In addition, the clock on the display is incorrect until the bike connects to the Specialized app. This is not expected behavior. Why is it doing this? Has anyone else experienced this?

NOTE: When not in use, the bike is in my garage. The garage is cool and dry. The bike has never been wet--either while riding or by being washed by a hose. Once the bike connects to the Specialized app, the clock immediately resets to the correct time. I have a Range Extender, but it is not on the bike when this unattended power-on happens. Otherwise, the bike performs perfectly.

Thanks!

John

A visit at a Specialized dealer seems to be necessary...

Actually, I am already working with my dealer to solve this. They have downloaded error codes from the bike and forwarded them to Specialized. Specialized suggested replacing a wiring harness which the dealer has done. Since that did not solve the problem, the dealer has communicated again with Specialized and we are expecting a further response in the next day or so.

I asked three AI websites for their opinion on what’s going on—ChatGPT, Gemini and Copilot. The conclusion seems to be that the Mastermind H3 may need to be replaced. We’ll see what Specialized has to say.

I have a new SL2 5.0. About 4 weeks old, 60 ish miles.

Does exactly the same thing. Happened 2 times this week.

Maybe related, the LBS swapped the stock handlebar for a new one with more rise. I helped the mechanic do it. It is quite tricky to get the two wires for the light and display threaded into the bar clamp. They popped out and got pinched on the first try. Maybe the wires got damaged?

I’m sure every bike has to have the handlebars attached as part of the LBS building procedure.

Bike never turned itself on before the handle bar swap.

John, any update?

@mcdenny,

Yes, I do have an update. After replacing the wiring harness did not solve the issue, Specialized sent my dealer a new Mastermind H3 display. That fixed it! Everything is working perfectly now.

Good luck resolving things with your bike.
