    Crosstrek (24-25') Start / Stop Eliminator

    Works just like it says

    Posted by Kurt Clark on Jun 16th 2025

    installation took about 5 minutes. Works just like it's supposed to. The only way it could be better is if the Auto Vehicle Hold would stay on as well. I'm so glad I don't have to wait on the infotainment system to figure out what it's doing just to turn that stupid thing off.

    One suggestion

    Posted by Ranhead on Apr 22nd 2025

    Maybe it's my fat fingers, but using a small flathead screwdriver makes disconnecting the electrical plugs much easier.

    Great product!

    Posted by Clarke on Mar 18th 2025

    I was able to install the Start / Stop Eliminator in less than 10 minutes, and it only took that long because my Crosstrek sport was slightly different than the Crosstrek in the video. Otherwise, very simple and quick process.

    Auto Start-Stop Eliminator

    Posted by Bob on Feb 11th 2025

    Once installed, product is working as advertised. Apparently, it adds inline memory of user's last switch setting of the vehicle's auto Start-Stop system. Thus, on next engine starting, the auto Start-Stop does NOT default to on, but to the user's last choice. Bravo! One star off as installation is slightly more difficult than as highlighted in the video. Tech help was great attempting to overcome the usually tedious problem associated with release of multi-pin electrical Connectors in very tight spaces. There's probably a tool that makes it easier.

    Crosstrek (2024) Start / Stop Eliminator

    Posted by Joe on Jul 30th 2024

    All is good as long as the device holds up, I hated the Auto Shutoff especially when forget to turn it off. Now it is off and I don’t have to remember to turn it off. Very happy I found your product and install video
