Breaking into auto mechanics and service tech can look daunting, but don't despair! We asked our service staff how they did it and what they'd recommend for newcomers!

The success of the 2026 Jeep Freedom Ride belongs to an incredible community.

Thank you to every Jeep owner, sponsor, volunteer, and supporter who joined us. This is what the Jeep community is all about—coming together to make a real difference.

Because of the generosity of our riders, sponsors, donors, and volunteers, we were able to present funds that are a symbol of remembrance, support, and hope. By coming together in honor of Deputy Keidel, who served the Midland County Sheriff's Department for 16 years, we raised funds to establish a college fund for his 4-year-old son.

We are honored to help carry forward his legacy by supporting his family and raising awareness of the well-being of those who continue to serve.
