What stands out
Of the 12 model years of GMC Canyon we track for powertrain problems, this one carries the most owner complaints on file — 34.
Owners have filed 34 powertrain complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This Preliminary Information communication provides information to the technician about vehicles that may have a delayed engagement into drive, shudder at a launch, or the transmission is slipping when shifting into 1st, 2nd, 3rd or 4th gears. This may be due to loose stator support to pump cover bolts causing a leak at the stator support to pump cover gasket. Technician will check for the bolts to be loose. If any of the bolts are loose or the gasket is misaligned or leaking, the transmission pump cover must be replaced and the 1234 clutch plates should be inspected for being distressed and repaired as needed.

The failure pattern owners describe
The 2016 GMC Canyon powertrain complaints cluster heavily around transmission behavior and drivability. Owners describe inconsistent shift points and gear selection, particularly in stop-and-go driving between 20-40 mph. The transmission reportedly hunts for the correct gear, hesitates or lags when accelerating from a standstill or after coasting, then jerks hard into gear once it responds. Many report the truck reaches third or fourth gear at unusually low speeds (15–20 mph), forcing them to drive in tall gears with minimal throttle response.
Owners also describe shuddering and vibration throughout the transmission, especially when reaccelerating or shifting under load. Several report dangerous delay in acceleration when merging onto highways or turning into traffic, with gaps of 2–3 seconds between pedal input and engine response. A few mention the transmission failing to downshift properly from higher gears when slowing, forcing hard acceleration to force a downshift.
Secondary issues include the transfer case and 4WD actuator cycling on and off without driver input, the ignition key becoming stuck in accessory position (related to the shift interlock), and sporadic electrical gremlins (dashboard display glitches, temporary loss of power). One owner reported the torque converter as the cause of shaking and poor acceleration. Dealers typically said behavior was normal, even after software updates and fluid changes—the latter sometimes reaching six services by 72,000 miles.

Failure modes owners describe
Transmission shift logic/calibration failures
Transmission selects incorrect gear and holds it too long or too short, resulting in poor driveability, lag during acceleration, and hunting between gears, especially in low-speed city driving and highway merges.
When: From new to early ownership; worsens over time. Issues reported as early as first week of driving; some worsen by 72,000 miles.
Symptoms owners cite: Transmission reaches 3rd or 4th gear at 15–20 mph, staying in tall gear; Delay or lag when accelerating from stopped or after coasting, requiring 2–3 seconds or hard pedal pressure; Hunting between gears, especially between 2nd and 3rd, feeling like neutral; Shuddering and jerking when shifting under load; Hard, violent clunk into gear after hesitation; Downshift slow to occur from higher gears, then skips gears with engine screaming; Vehicle struggles to accelerate in stop-and-go traffic at 20–40 mph
Repairs/costs cited: Dealers performed transmission fluid and filter changes (up to six services reported); some owners cite ECM reprogramming or software updates mentioned by dealers or in warranty bulletins (PIP 5342A, dated 12/21/2015). Owner mentions 2015 Canyon fixes included ECM patch updates and lower valve replacement, but 2016 models reportedly did not receive these fixes. No successful resolution reported.
Recalls/TSBs owners mention: PIP 5342A (dated 12/21/2015) issued; dealers told customers this behavior was normal; GM did not offer recall or repair campaign for 2016 models. One owner states GM publishes paper detailing symptoms and instructs dealers not to take action beyond software updates.
Transmission shuddering and vibration
Vehicle shakes, shudders, or vibrates through the transmission during acceleration, gear changes, or normal driving, reported as present from early ownership and worsening over time.
When: Starting at 15,000–35,000 miles and worsening through ownership.
Symptoms owners cite: Shuddering when accelerating in all conditions and speeds; Entire vehicle shakes front to rear between gears; Shaking when reaccelerating after coasting downhill or on secondary roads; Shaking uncontrollably without warning during 10–40 mph driving; Hard, thump-like shifts when turning and accelerating
Repairs/costs cited: Transmission fluid and filter changes performed; torque converter replacement performed in one case (owner suspects torque converter as cause). Multiple mechanics told one owner to drive it until transmission fails.
Recalls/TSBs owners mention: Dealers stated shuddering was normal; no service bulletins or recalls issued to address.
4WD actuator and transfer case control failures
Transfer case and 4WD system unexpectedly engage without driver input, or fail to disengage properly. Service 4WD warning illuminates. Transfer case control module and actuator replaced multiple times without resolution.
When: Early ownership, recurring after each repair (failures at 6,883 miles reported).
Symptoms owners cite: Powertrain shifts to 4WD automatically during normal driving; Service 4WD warning indicator illuminates; 4WD will not disengage or engage as commanded by driver; Vehicle repeatedly enters 4WD mode during highway driving
Repairs/costs cited: 4WD actuator replaced; transfer case control module replaced; transfer case actuator replaced; connector kit replaced; computer reprogrammed. Failures recurred days after each repair.
Recalls/TSBs owners mention: GM referred contact to dealer for resolution; no permanent fix provided.
Ignition key stuck in accessory position
Ignition key does not fully release or turn off when truck is placed in Park. Key becomes stuck in the accessory position, draining the battery. Root cause is the gear shift assembly (Part # 23397472) not reliably confirming transmission is in Park to the solenoid lock.
When: Intermittent throughout ownership.
Symptoms owners cite: Key stuck in ignition in accessory position; Key will not turn to OFF to release from ignition; Ignition and key become very hot after 20+ minutes of driving; Battery drains due to key stuck in accessory mode; Issue resolves temporarily after shifting through multiple gears and restarting
Repairs/costs cited: Gear shift assembly (Part # 23397472) replacement typically resolves the issue per dealer admission.
Recalls/TSBs owners mention: No recall issued; one dealer eventually admitted this is a known problem.
Sporadic electrical and dashboard anomalies
Infotainment touchscreen unresponsive or operates erratically; digital speedometer and gauges malfunction; entire dashboard goes dark temporarily during driving without affecting engine operation.
When: Present from new; reported at 15,000–35,000 miles.
Symptoms owners cite: Touchscreen unresponsive to inputs or changes inputs randomly; Digital speedometer display changes randomly; Entire dash, radio, gauges, and lights go black for 20–30 seconds, then reboot; Vehicle continues to drive normally during electrical blackout
Repairs/costs cited: Dealership inspected vehicle twice and found nothing wrong. No repairs performed.
Recalls/TSBs owners mention: Dealers stated all systems were operating normally; no action taken.
Loss of power and limp mode activation
Vehicle loses power and goes into limp mode, sometimes related to emissions sensor codes or DEF system failure. Engine bogs at low RPM, vehicle shuts off while driving or braking, vehicle refuses to accelerate unless downshifting occurs first.
When: After warranty expiration (72,000 miles in one case); varying mileages reported.
Symptoms owners cite: Vehicle loses power and enters limp mode; Temperature gauge fluctuates toward red line; Vehicle shuts off while driving on city streets or highways; Engine bogs and misfires at RPM below 2,000; Vehicle refuses to accelerate at low RPM; DEF system fails, triggering limp mode; Emissions sensor faults (NOX, particulate) trigger limp mode
Codes mentioned: NOX sensor faults (owner states these are false), Particulate sensor faults
Repairs/costs cited: Owner notes dirty particulate sensors can be cleaned to resolve faults. Dealership quoted $8,000–$10,000 for transmission replacement. One vehicle in shop for 3 weeks with no diagnosis; exhaust filter actively cleaning repeatedly.
Recalls/TSBs owners mention: GM and dealers did not provide diagnosis or repair; DEF/emissions system reportedly programmed to restrict travel for any emissions-related fault.
Torque converter failure or malfunction
Torque converter not functioning properly, causing poor acceleration, shaking, vibration, and vehicle feeling like it will shut off on highway or in traffic. Suspected but not always confirmed by diagnostic testing.
When: Reported at various mileages; one owner noted symptoms starting 08/01/2021 after earlier water coolant valve issues.
Symptoms owners cite: Slow acceleration despite throttle input; Vehicle shakes and vibrates; Vehicle feels like it will shut off on highway or in heavy traffic; Acceleration unresponsive during highway driving
Repairs/costs cited: Water coolant valve replaced by dealership but issue persisted; torque converter replaced by independent mechanic (not inspected, test-driven and replaced). No fault codes indicated on dashboard.
Engine stalling during braking or at stop
Vehicle shuts off unexpectedly while braking, stopped at traffic light, or during normal operation. Engine must be restarted before vehicle can operate.
When: Early ownership; one report at 1,000 miles.
Symptoms owners cite: Vehicle shuts off during braking; Vehicle shuts off while stationary with brake pedal depressed; Engine stalls while stopped at red light or stop sign; RPMs suddenly increase and vehicle attempts to drive forward while stationary

What owners are reporting 2 most recent
Slow and go driving 20-40mph after coasting and trying to accelerate again the transmission bucks hesitates trying to find a lower gear. It can't decide which gear to go into and just sputters and chugs until I push the accelerator 1/2 way down or more the finds its gear and rockets off. This type of driving not safe at all. This happens all the time since practically new. Gm claims its normal.…
Vehicle frequently shuts off during braking or while stopped and must be restarted before the vehicle can operate again. Vehicle experiences violent gear changes and significant lagging during periods of moderate acceleration at low speeds. Gear changes result in either severe unresponsiveness and a general lack of acceleration or an aggressive gear change that jerks the vehicle and spins the…
