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.

full bulletin at NHTSA ↗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 2017 GMC Canyon powertrain exhibits chronic transmission issues across multiple failure modes. The dominant complaint involves torque converter shudder and slippage in the 8-speed transmission, starting at highway speeds (40–70 mph) and during acceleration, with hard shifts at specific speeds (5 and 18 mph). Owners report the converter fails or deteriorates as early as 12,000–16,000 miles. One owner's investigation concluded the root cause is an undersized torque converter introduced in 2017 to reduce vehicle weight. Transmission fluid flushes and converter replacements—the standard dealer fix via TSB 18-NA-355—often fail to resolve the problem; some replacement converters fail again within 16,000 miles.
Separate issues include transmission refusal to engage at startup (requiring 10+ minutes idle before drive works) and complete transmission failure requiring replacement at 64,000+ miles. A diesel-equipped truck stalled unexpectedly in cold weather below 1/4 tank, with the dealer confirming this affects other Canyon diesel units.
Owners report aluminum and metal chips found in transmission fluid, indicating internal damage. Multiple owners state GM has acknowledged the problem since 2016 but claims no fix exists. One owner noted GM is not responding to calls, and dealers uniformly report nothing further can be done.

Failure modes owners describe
Torque converter shudder and slippage
Undersized torque converter design (per owner investigation in #1) causes driveline shudder, hard shifts, and converter slippage. Issues begin on 2017 model year across Canyon/Colorado with 8-speed transmission. Owners report shuddering at acceleration, highway speeds (40–70 mph), and during deceleration/cruise control. Some experience torque converter lockup failure at low speeds (around 12 mph with RPM climbing from 2000–4000).
When: 12,000–16,000 miles reported for converter failure; shudder symptoms appear as early as 28,000 miles and throughout vehicle life
Symptoms owners cite: Shuddering or vibration at highway speed (40–70 mph); Hard shifts at 5 and 18 mph; Rattling or rocking during acceleration; Torque converter slippage with engine RPM spikes; Banging in drivetrain; Shudder during deceleration and cruise control speed reduction
Repairs/costs cited: Transmission flushes and torque converter replacement per TSB/bulletin; some owners report replacement converters fail again within 16,000 miles. One owner (#5) had transmission replaced with remanufactured unit but experienced slippage immediately upon restart. Dealer in #4 stated converters will fail again. Back-order delays reported.
Recalls/TSBs owners mention: TSB/Bulletin 18-NA-355 issued (transmission fluid flush and torque converter service). Class Action lawsuit filed in California for 'Chevy Shake.' Dealer in #2 advised not to drive with less than 1/4 tank in winter (diesel model). GM stated in #9 'there is nothing they can do to fix.' Some dealers claim issue is known since 2016.
Hard engagement and stalling on startup
Transmission fails to engage smoothly after starting; vehicle behaves as if in neutral. Owners must wait 10+ minutes before vehicle will move without severe jolting. When driven sooner, transmission slams hard into drive with violent jerk and shudder before functioning normally.
When: Present from early ownership; reported as ongoing almost daily in one case since July 2019
Symptoms owners cite: Transmission engages as if in neutral immediately after startup; Hard slam/jerk into drive when shifted too soon after start; Shuddering after hard engagement; Requires prolonged idle (10+ minutes) before vehicle will move smoothly
Repairs/costs cited: No repairs documented. Dealers acknowledge multiple complaints but offer no fix.
Recalls/TSBs owners mention: GM stated 'there is nothing they can do to fix' per #9.
Transmission failure requiring replacement
Complete transmission failure occurs across a range of mileages. Owners report loss of drive, inability to accelerate, or transmission simply ceasing to function. One case involved aluminum and metal chips in transmission fluid, indicating internal wear.
When: 64,000 miles (#11); 96,000 miles (#8); occurring across multiple mileage points
Symptoms owners cite: Vehicle fails to respond to accelerator pedal and jerks forward; No drive engagement despite proper shifting; Transmission slipping downhill with loud revving; Complete transmission malfunction
Repairs/costs cited: Full transmission replacement required at owner expense in #11. In #5, remanufactured transmission installed but exhibited slippage immediately. In #8, transmission on backorder and not repaired. Hard shifts and grinding sounds noted before failure.
Diesel engine stalling at low fuel levels in cold weather
Diesel-equipped 2017 Canyon unexpectedly stalls while driving when fuel tank drops below 1/4 full during cold ambient temperatures (0–10°F). Engine shuts down with no warning; vehicle loses all power in traffic, creating safety hazard. Dealer confirms this is a known issue with other Canyon and Terrain diesel models.
When: ~14,200 miles at 0°F with 1/3 tank; ~15,100 miles at 10°F with 1/8 tank
Symptoms owners cite: Engine dies suddenly while driving; Dash illuminates with multiple fault codes; Vehicle enters reduced power mode; Smell of fire/burning reported; No warning before shutdown
Codes mentioned: Multiple codes reported but not identified in narrative
Recalls/TSBs owners mention: Dealer kept vehicle multiple days; GM and dealer unable to identify or fix root cause. Workaround advised: do not drive with less than 1/4 tank during winter. Dealer acknowledged this affects 'a few other Canyon and Terrain diesel models.'
Transmission shifting issues and jerking
Vehicle exhibits unpredictable acceleration behavior: hesitation, jerking, or sudden rapid acceleration without driver input. After transmission service, issues often recur or persist despite multiple repair attempts.
When: 28,000 miles in one case; recurring throughout ownership
Symptoms owners cite: Hesitation and shake when pulling into traffic; Sudden rapid acceleration without warning; Jerking forward during normal driving; Acceleration inconsistency
Repairs/costs cited: Transmission flushed and torque converter replaced at dealer (#6), but hesitation and shaking continued after repair.
Recalls/TSBs owners mention: Manufacturer notified and case number assigned (#6). No resolution documented.
Transmission refusal to engage
Transmission enters neutral without driver input or refuses to engage into drive or reverse despite shifting into those gears. Vehicle becomes immobile, stranding owner at intersections.
When: Early in ownership; one case on 2/12/2017 at low mileage
Symptoms owners cite: Transmission shifts into neutral without driver action; Drive gear will not engage; Reverse will not engage; Vehicle stuck and unable to move
Repairs/costs cited: Dealer kept vehicle 2.5 days, reported unable to find problem; vehicle left unrepaired.

Torque converter fails at 12000 miles for many. There is a GMC notice out since 2016. Mine failed at 16000 miles and the one they replaced will likely fail again in another 16k miles. This is bad. I noticed it when I pressed on the accelerator and as I increased speed up to 45 MPH. It rattled and rocked badly. The GMC repairman said, "yeap.....ever since 2016 all these [xxx] torque…
This is 2nd $40,000 canyon I've been taken for! 1st was 2016, and transmission would take off after flooring it, as it would just 'lay down' and scared the wife so much, and wouldn't drive it! Had to repurchase an 2017, with the 8 spd trans, and even worse! It shakes and shudders even after fluid flush, then new torque converter! Then was told, there's nothing more gm can do for you!?? Really?…
