The GM 8L45/8L90 8-speed automatic transmission is prone to torque converter shudder, harsh shifts, and hesitation. This is often caused by fluid breakdown and can lead to internal wear if not addressed. TSB 18-NA-355 recommends a specif…
Common failures include blend door actuators leading to incorrect temperature output or airflow, and premature AC condenser leaks resulting in a loss of cooling. Repairs can be labor-intensive due to dashboard disassembly.

2019 GMC Canyon Mileage Danger Zones
The mileage windows when the 2019 GMC Canyon most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Early Warning Zone
At this mileage, vehicles are typically still under factory warranty. Look for early signs of the 8-speed transmission shudder or infotainment glitches, as these often manifest early.
Maintenance & Transmission Check Zone
Many Canyons will be out of basic warranty here. The 8-speed transmission issues are often pronounced, and HVAC problems may begin. Regular fluid changes become more critical.
Elevated Risk Zone
