Owners of 2024 GMC Canyons built from March through June 2024 report LED headlamps flickering intermittently from delivery. The headlights blink off and back on—typically every 1 to 5 minutes—whether the truck is parked or driving, in daylight or darkness. No dashboard warnings precede or accompany the flicker. Owners confirm the behavior is reproducible by manually turning on headlights in daylight and that it occurs regardless of whether low beams, high beams, or auto-dimming are selected. Some headlights eventually fail completely on one side.
The flicker looks to oncoming and following drivers like the owner is intentionally flashing brights or high beams at them. Owners report being flashed back, brake-checked, tailgated, and yelled at by confused drivers. One owner nearly drove under an 18-wheeler when the beam dipped during a pass. Pedestrians and cyclists misinterpreting the flicker as a yield signal create intersection hazards. No fault codes or warning lights appear.
GM issued TSB PIT6203 in July 2024 acknowledging the defect as an internal LED controller problem. Dealers initially replaced headlamp assemblies per the bulletin but later were directed not to. Control module swaps haven't resolved it. Headlamp assemblies remain backordered with no ETA. A separate turn-signal issue—where right turns trigger unwanted left-signal flashing—also remains unfixed. One owner reports a headlamp repair attempt left his driver's side stuck on high beam permanently, creating a blinding hazard for oncoming traffic with no resolution available.
LED headlamps flicker or blink off and on repeatedly, occurring every few seconds to several minutes. The flickering happens regardless of whether the vehicle is moving or parked, in daylight or darkness, and persists even with remote start when the vehicle is unoccupied. Owners report no dashboard warning lights or fault codes preceding or accompanying the issue. The problem is reproducible in daylight by manually turning headlights on via the control center. Some owners report the flickering can progress to complete loss of illumination on one or both sides.
When: Build dates narrowly clustered Spring 2024 through June 2024; issue present from delivery or within first few weeks of ownership; mileage at discovery ranging from near 0 to 5,000 miles
Symptoms owners cite: Headlights blink off and back on in a fraction of a second to a few seconds; Both low beams and DRLs flicker together; Flicker frequency typically every 1-5 minutes but varies; Sometimes only one side flickers; sometimes both sides; Occasional complete loss of illumination on one or both headlights; Flicker independent of headlight control position (auto, manual, high beam); No dashboard warning lights or fault messages; Issue reproducible in controlled daylight testing
Repairs/costs cited: Dealers initially instructed to replace headlamp assemblies per TSB PIT6203, but GM later directed dealers NOT to replace them (July 2024). Control module replacement attempted by some dealers without success. Parts remain on backorder with no ETA. GM stated to be working on software solution and headlight redesign but no solution made available to dealers or owners as of complaint dates.
Recalls/TSBs owners mention: GM Technical Service Bulletin PIT6203 (July 16, 2024) and PIT6203A (July 30, 2024) issued acknowledging 'Headlamp or DRL Flicker or Flash' as known issue affecting 2024 Canyon build. NHTSA Campaign 24V673000 (Exterior Lighting) issued but parts for recall repair were not yet available at time of complaints. Initial guidance to replace headlamp assemblies was reversed. GM stated to be redesigning headlights and working on software fix with no timeframe provided.
When the turn signal is manually deactivated or automatically cancels after a right turn, the opposite (left) turn signal activates and flashes 3-5 times before stopping. The issue occurs only with right-hand turns. Drivers report this creates confusion because oncoming or following drivers may misinterpret the sequence as an actual left-turn signal, potentially causing them to move into the vehicle's path or adjust their own driving in response to a false signal.
When: Noticed early in ownership; one owner reported issue first noticed one week after September 13 purchase (September 20 notification)
Symptoms owners cite: After completing a right-hand turn and deactivating the turn signal, the left turn indicator flashes for 3-5 seconds; Issue only occurs with right turns, not left turns; Readily reproducible on multiple occasions; No warning lights or prior indications of failure
Repairs/costs cited: Owners report taking vehicle to dealership for evaluation but no repair notes are documented in these narratives.
Recalls/TSBs owners mention: GM issued a bulletin (referenced but not explicitly numbered in narratives) that provides no resolution to the issue. Dealer acknowledges the problem but no fix has been made available.
After a headlamp flicker recall repair attempt, the driver's side headlamp was left in a permanent high-beam state with no ability to turn it off. This creates a blinding hazard for oncoming traffic and has prompted dangerous close calls.
When: Occurred during recall repair attempt; vehicle delivered August 10, 2024
Symptoms owners cite: Driver's side headlamp remains on high beam continuously; No way to turn off the affected side; Oncoming traffic blinded and crossing center line; Vehicle safety compromised
Repairs/costs cited: Dealer states entire headlight assembly must be replaced but is on backorder with no expected date. Owner has open case (GM Case Number 9-14098737984) with no resolution.
Recalls/TSBs owners mention: No response documented other than case number assignment with no outcome.

When the right turn signal cancels after completing a right turn, the left turn signal activates, flashing 3 times. This appears to be the result of a defective design with the turn signal level. The dealer has acknowledged the problem and has stated that there is a bulletin from GM from several months ago which does not provide any resolution to the issue. This is a safety issue since the…
When the right hand turn signal is cancelled following a right hand turn, the left turn signal flashes to indicate a lane change. This would falsely indicate intention of changing lanes.
Turn signal not working properly and GM has not issued a solution to dealerships. Issue: When you use your turn signal to change lanes or turn onto a new street, the turn signal will flash to let drivers know. However, when you turn off your turn signal manually or the truck turns off the turn signal automatically when you turn the corner, instead of the turn signal stopping, it starts flash…

God was with me for sure.. i have not received any info on the recall and went by the dealership where I bought it and they sAid I would…
When I make a right turn, after completing it, my left turn signal flashes three times. This is very confusing to other drivers around me and I’m concerned could cause an accident. This has been occurring since I purchased the vehicle. The dealership advised that the headlight flicker repair would likely fix it, but it did not.
