About MaintainEV – Independent Mobile Tesla Service

Independent Tesla Service Built on Real-World Experience

MaintainEV is an independent mobile Tesla service, diagnostics and maintenance business serving Alberta and Western Canada. We bring specialized Tesla service directly to customers at their homes and workplaces.

MaintainEV was built around practical, high-mileage Tesla ownership and hands-on experience. Owner Darryl Kolewaski has nine years of experience working with Teslas, including years of operating Teslas in high-mileage commercial use and maintaining his own Tesla Model S to more than 800,000 kilometres.

That experience shapes the way MaintainEV approaches service: understand the vehicle, diagnose the problem properly, maintain the systems that affect reliability and efficiency, and help owners keep their Teslas on the road for the long term.

Specialized Tesla Knowledge

Teslas are different from conventional vehicles, and effective diagnosis often requires more than reading a generic fault code. MaintainEV combines hands-on vehicle experience with Tesla-specific diagnostic capabilities to help identify problems accurately and provide owners with clear information about their vehicles.

Mobile Service

Many MaintainEV services can be performed at your home or workplace. Regular mobile service is available in the Edmonton area, with scheduled service and travel throughout Alberta and Western Canada depending on location and demand.

Our Approach

MaintainEV focuses on practical maintenance, transparent information and helping Tesla owners make informed decisions. Whether the vehicle is approaching the end of its warranty, has an unexplained alert, needs preventative maintenance or has accumulated substantial mileage, the objective is the same: keep the vehicle reliable, efficient and useful for as long as possible.

Built to drive. Maintained to last.
