What stands out
Of the 10 model years of GMC Canyon we track for engine problems, this one carries the most owner complaints on file — 14.
No new NHTSA engine complaint has been filed on this vehicle in over 13 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine 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 service bulletin provides guidelines and diagnostic/repair information to technicians regarding vehicle engine oil consumption.

The failure pattern owners describe
Owners report a cascade of engine-related failures in the 2005 GMC Canyon. The most significant is a manufacturing defect in cylinder heads with bad intake valve seats, covered under TSB #07123A with a 7-year/100,000-mile special coverage that has since expired for many owners. Replacement costs run $3,500, and multiple owners say they never received recall notification despite the widespread issue.
Intermittent engine stalling occurs frequently, sometimes with 20-minute restart delays. The Passlock security system malfunctions intermittently, disabling fuel and ignition with the correct key and proper use—a safety hazard, especially in emergency evacuations. Owners report 10-minute lockout periods before the truck will start again, and the problem appears widespread in owner forums.
Camshaft solenoid and related actuator components fail repeatedly at short intervals (one owner replaced parts within 150 miles of initial repair). Fuel mileage drops sharply from 27 to 16 MPG, and excess fuel injection creates a gasoline smell and fire risk. Check engine lights come on repeatedly with codes P0300, P0106, P0506, P0014, and P0017. Oxygen sensors, catalytic converters, and exhaust systems fail in related chains. One owner's cylinder head warped and lost compression at exactly the time a TSB was issued for that problem. Rough idling and hard vibrations occur even after warranty extension, only to recur after coverage expires.
Failure modes owners describe
Defective Cylinder Head (Intake Valve Seat)
Factory manufacturing defect in cylinder heads with defective intake valve seats, covered under TSB #07123A with 7-year/100,000-mile special coverage that has since expired for many owners.
When: Low mileage (52,000 miles reported); issue present at manufacture but not identified until years later
Symptoms owners cite: Engine failure requiring cylinder head replacement
Repairs/costs cited: $3,500 to replace defective cylinder head; owners report dealer denial of coverage after warranty expiration despite low mileage
Recalls/TSBs owners mention: TSB #07123A; 7-year/100,000-mile special coverage (expired 2013 in complainant's case); owners report lack of notification regarding recall
Passlock Security System Malfunction
Intermittent failure of the GM Passlock anti-theft system causes the fuel and ignition to disable without legitimate trigger, preventing engine start.
When: Intermittent; occurs with factory key and proper use
Symptoms owners cite: Intermittent no-start with factory key; Passlock warning light on dashboard; 10-minute lockout period required before attempting restart; Multiple lockout periods sometimes needed before engine starts; Engine runs normally once started
Repairs/costs cited: No repairs documented in complaint; complainant notes widespread issue reported in owner forums
Camshaft Solenoid/Actuator Failure
Repeated failure of camshaft solenoid and related actuator components requiring replacement multiple times; poor fuel control results.
When: 44,000 miles; recurring at short intervals (150 miles between replacements in one case)
Symptoms owners cite: Multiple replacement needs in short timeframe; Fuel mileage drop from 27 to 16 MPG; Gasoline smell; Engine sputtering and stalling; Excessive fuel injection into intake
Codes mentioned: P0014, P0017, P0300
Repairs/costs cited: Camshaft sensor and solenoid replacement; owner notes GMC stocks part regularly, indicating known failure pattern; fire hazard from excess fuel
Rough Idling and Hard Vibration
Engine idles roughly with noticeable hard vibrations at low speed or idle; warranty extension issued but problem recurs after expiration.
When: Under 1,000 miles initially; recurred by 21,000 miles after warranty expired
Symptoms owners cite: Rough idle; Hard vibrations felt in vehicle; Recurring issue after extended warranty period ends
Repairs/costs cited: Dealer unable to determine root cause; no permanent repair achieved
Recalls/TSBs owners mention: Manufacturer issued warranty extension notice, but coverage expired before problem recurred
Engine Stalling (Intermittent)
Engine stalls unexpectedly during driving or at low speed, particularly in stop-and-go traffic or during highway maneuvers; vehicle restarts but issue persists.
When: 15,000 to 50,000+ miles; intermittent
Symptoms owners cite: Complete engine stall while driving; Stalling in stop-and-go traffic; Stalling during turning maneuvers; Stalling on highway on-ramp at 50 MPH; Easy restart after stalling; Issue worsens over time
Codes mentioned: P0106, P0300, P0506
Repairs/costs cited: Head, exhaust, and intake valve replacement attempted but stalling continued to worsen; one incident involved 20-minute restart delay
Excessive Electrical Current to Engine
Abnormally strong electrical current flowing to the engine causes visible smoke from vents at high mileage.
When: 123,000 miles
Symptoms owners cite: Smoke coming from vehicle vents
Repairs/costs cited: Authorized dealer recommended full engine replacement; repaired by independent mechanic instead
Oxygen Sensor and Catalytic Converter Circuit Failure
Check engine light triggered by oxygen sensor failure; replacement followed by similar failure five days later; catalytic converter and exhaust intake also implicated in chain of related faults.
When: Low mileage (used vehicle purchase); repeated failure within days of first repair
Symptoms owners cite: Check engine light; No rough running or noise initially; Repeated warning light after repair
Repairs/costs cited: Oxygen sensor replacement; followed by catalytic converter, oxygen sensor, and exhaust intake repair; issues resolved after third service visit
Compression Loss and Head Warping
Number 3 cylinder loses compression and cylinder head warps; manufacturer issued TSB #10 (dated March 10) two days before failure occurred.
When: March 13; timing coincides with TSB issuance March 10
Symptoms owners cite: Loss of compression in number 3 cylinder; Head warping
Repairs/costs cited: TSB issued March 10 for this problem; owner complaint filed March 13
Recalls/TSBs owners mention: TSB issued March 10 for compression loss and head warping problem
