What stands out
Of the 15 model years of GMC Canyon we track for electrical problems, this one carries the most owner complaints on file — 23.
The failure pattern owners describe
Buyer takeaway: The 2024 GMC Canyon has a known and widespread headlight flicker issue that GM has acknowledged but cannot yet fix—lights turn off and on every 1–2 minutes, confusing other drivers and creating a real nighttime safety hazard. Additionally, a handful of owners report battery drain, brake function problems, electrical wiring failures, and parts shortages leaving vehicles stranded at dealerships with no ETA for repair.
The headline issue is headlight flicker affecting new 2024 Canyons built from May 2024 onward. Lights—including LED daytime runners and HID low/high beams—flash on and off randomly every 30 seconds to 5 minutes, regardless of manual or auto setting, while driving or parked. Owners say other drivers respond by flashing high beams, brake-checking, or pulling over thinking they're being signaled to proceed. GM issued bulletin PIT6203 in July 2024 acknowledging the problem; dealerships initially tried replacing headlight assemblies, but GM cancelled that fix after finding replacement units had the same defect. Parts are on national backorder with no ETA. The infotainment screen—the only way to control lights in this model—also fails and is backordered.
Beyond headlights, owners report battery drain requiring daily starts to prevent discharge, brake function loss after system updates, and wiring shorts in the headliner triggering check-engine lights. One owner's anti-lock brake module is backordered until late October with the vehicle deemed unsafe to drive. Turn signal overcancellation, audio system silence 75% of the time, and random trailer-brake disablement during towing round out the electrical gremlins. GM refused one owner's buyback request despite multiple failed repair attempts.

Failure modes owners describe
Headlight and DRL flicker/flash
Headlights and daytime running lights flicker, flash, or turn off and on intermittently, occurring randomly every 30 seconds to 5 minutes or roughly every 1–2 minutes. Affects low beam, high beam, HID, and LED DRL regardless of manual or auto setting. Occurs while driving and parked. Owners report other drivers respond to the flicker by flashing high beams, brake-checking, or pulling over thinking they're being signaled.
When: Begins within days to weeks of purchase; complaints filed from May 2024 onward; affects vehicles built May/June 2024 and later
Symptoms owners cite: Headlights and DRL flicker on/off intermittently; Flicker every 30 seconds to 5 minutes or 1–2 minutes; Occurs randomly regardless of driving or parked state; Occurs regardless of manual or auto headlight setting; Other drivers perceive flicker as high-beam flashing; Confusion and hazard-like behavior from oncoming/following drivers
Repairs/costs cited: Dealerships initially advised replacing headlight assemblies per bulletin PIT6203; GM later cancelled that direction after finding replacements had the same issue. Infotainment display used to control headlights may also malfunction. Parts on national backorder with no ETA. No current fix available from GM as of complaint dates.
Recalls/TSBs owners mention: GM Document ID 6691954, bulletin #PIT6203 'Headlamp or DRL Flicker or Flash' (July 16, 2024). GM aware of issue; engineering working on resolution. Parts delayed/on national backorder. Dealership advised to stop replacing headlamp assemblies. GM offered no solution or loaner vehicles.
Infotainment display malfunction/inoperability
Infotainment screen that controls headlight functions becomes inoperable, preventing manual control of lights. Screen is the only way to operate headlight functions in this model (no physical knobs/buttons).
When: Within days of purchase; on national backorder as of complaint dates
Symptoms owners cite: Infotainment screen inoperable; Cannot adjust or turn on/off headlights via screen; Headlights stuck on auto mode; Screen on national backorder
Repairs/costs cited: Infotainment screen on national backorder; no ETA provided by GM.
Recalls/TSBs owners mention: GM informed owner parts are delayed with no ETA. Screen on national backorder.
Battery drain and brake system function loss
Battery drains spontaneously, forcing owners to jump-start vehicle. After jump-start, brake function is impaired and vehicle must be driven at reduced speed (under 50 mph). Multiple incidents requiring battery drain resolution; battery will die if not started every 24–36 hours.
When: Occurring during or after system updates; on-going issue
Symptoms owners cite: Battery drains and dies spontaneously; Requires jump-start; Brakes do not function normally post-restart; Dashboard message indicating slow operation recommended; Brake engagement failure or near-failure after update; Battery dies within 24–36 hours if vehicle not started
Codes mentioned: Check engine light
Repairs/costs cited: Dealership diagnostic found nothing wrong with battery or other systems. Owner reports having to start/run engine daily to prevent battery drain.
Electrical wiring shorts and open circuits
Broken wire in headliner (right side) caused check engine light. Later, short circuit in wire caused parking assist code. Dealership initially repaired broken wire; later ran new wire along frame to avoid proper repair (removing cab and bed from frame).
When: First issue 5/18/24; second issue discovered 7/29/24
Symptoms owners cite: Check engine light illuminated; Park assist code triggered; Wire shorts causing sensor codes
Codes mentioned: Check engine light, Park assist code
Repairs/costs cited: Dealership found and repaired broken wire in headliner on 5/22/24. Later found short in wire 7/29/24; ran new wire along frame instead of proper repair due to labor intensity (cab/bed removal required).

After completing a right turn, left turn signal flashes 3–4 times automatically. Also reported as turn signal overcancelling causing left signal to activate on right turns.
When: Post-turn behavior; reported in 2024 model vehicles
Symptoms owners cite: Left turn signal activates after right turn completion; Signal flashes 3–4 times without driver input; Overcancellation of turn signal
