Our Story.
Founded in 2012 by a group of systems engineers from the aerospace industry, Precision Auto Diagnostics (operating on sunshadearuba.com) brings military-grade scanning precision to the Canadian automotive market.
We realized that while cars were becoming "smartphones on wheels," the local repair shops were still using outdated analog tools. We invested over $2M in proprietary diagnostic software and high-speed cloud infrastructure to ensure we can talk to your car's brain better than anyone else.
Today, with a physical presence in Toronto and mobile units covering the Greater Toronto Area, we are Canada's premier destination for high-end automotive troubleshooting and software optimization.
