Three engines are covered, the 3.6L V6, the turbocharged 2.8L diesel inline-four and the 2.5L inline-four, which means three sets of tune-up specifications, three sets of torque values and three fuel systems to keep apart.

Known issues on the 2020 Canyon. Fourteen owner complaints appear against this model year, led by the powertrain and trailed by the electrical system and the service brakes. Those are systems the manual treats at length: automatic transmission and driveline overhaul with the fastener torque values that go with them, circuit diagnosis backed by complete wiring diagrams, and hydraulic brake service including bleeding procedures, component specifications and antilock brake diagnostics. Engine mechanical, cooling and emissions coverage rounds out the book for each of the three engines.
