2015 GMC Canyon

The 8-speed automatic transmission may exhibit harsh or delayed shifts, particularly between 2nd and 3rd gear and during low-speed deceleration. Owners report shuddering at highway speeds, sometimes accompanied by a noticeable clunk. The torque converter clutch is a frequent source of the shudder.

GM has released recalibrated transmission control module software under TSB 18-NA-355 for shudder concerns. A transmission fluid flush with Mobil 1 Synthetic LV ATF HP may resolve mild shudder. In persistent cases, torque converter replacement is necessary.

The 2.8L Duramax turbo-diesel engine may consume oil at a rate exceeding 1 quart per 2,000 miles. Owners notice low oil warnings between changes without visible leaks. Worn valve seals and piston ring issues are contributing factors, particularly in higher-mileage examples.

Monitor oil levels frequently and top off as needed. Dealers may perform an oil consumption test. If consumption exceeds GM's threshold, piston rings and valve seals may be replaced under powertrain warranty. Switch to GM-recommended dexos2 5W-30 synthetic oil.

The IntelliLink infotainment system may freeze, become unresponsive, or display a black screen. Apple CarPlay and Android Auto connections drop intermittently, and the backup camera feed may lag or fail to appear. Some owners report the system rebooting while driving.

Perform a hard reset by holding the power button for 10+ seconds. Check for and install software updates through the dealer. GM has released updated infotainment software to address stability issues. If the problem persists, the infotainment module may need replacement.

A check engine light may illuminate with DTC P0420 indicating catalytic converter efficiency below threshold. The problem is more common on the 3.6L V6 engine. Owners may notice slightly reduced fuel economy but otherwise normal driving behavior.

Verify the oxygen sensors are functioning correctly before condemning the catalytic converter. Replace upstream or downstream O2 sensors if faulty. If the catalytic converter has genuinely degraded, replacement is required. GM extended the emissions warranty to 8 years/80,000 miles for catalyst-related codes.

The air conditioning system may blow warm or insufficiently cool air, particularly in hot weather. The A/C compressor clutch may cycle rapidly or fail to engage. Internal compressor failure can contaminate the system with metal debris, requiring a full system flush.

Check refrigerant charge level and inspect for leaks at the condenser, evaporator, and line connections. Replace the A/C compressor if seized or noisy. Flush the system and replace the receiver-dryer and expansion valve if metal contamination is found.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 207, "Seating Systems."

If the seat-frame attachment hooks are not secured properly, the seat may not be adequately anchored to the vehicle, and in the event of a crash, the seat occupant could be at an increased risk of an injury.
