When does it fail?
Of the 44 lighting complaints filed for the 2017 GMC Yukon, here's the actual mileage breakdown — failures cluster heaviest at 25,000-50,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
Owners have filed 44 lighting 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.
Among the 5 model years of GMC Yukon in our records for lighting problems, this one ranks #3 by owner-complaint volume.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering lighting 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.

The failure pattern owners describe
The rear brake and tail light assemblies on 2017 GMC Yukons fail due to defects within the sealed LED circuit board. Owners describe cracks or broken solder joints at specific points on the circuit board, particularly a thin metal connector plate that breaks consistently. The failure is often intermittent—lights work, then stop, then work again when tapped or bumped, before failing permanently.
Failures occur as early as 19 months of ownership but typically between 3–5 years or 41,000–80,000 miles. Both driver and passenger side assemblies can fail independently or within months of each other. When the lights fail, brake lights and running lights are completely dark; turn signals and hazard lights may continue working. Because the assembly is sealed and integrated, there are no user-replaceable bulbs—the entire unit must be replaced at dealership cost of $650–$1,112 per side.
Owners note that modern LEDs should last 5,000+ hours and should not fail prematurely on a three-year-old vehicle with intermittent driving. Dealers acknowledge this is a known problem with multiple Yukon owners, yet GM refuses warranty coverage and claims it is not a safety issue. Notably, GM issued a recall on 2015–2016 Yukons for the same defective taillight assembly but has not extended that recall to 2017 models, despite identical parts and identical failures. Independent repair shops offer temporary fixes by soldering the circuit board, but owners report parts remain on backorder and replacement assemblies will fail again.

Failure modes owners describe
LED circuit board cracking/open connection in tail/brake light assembly
The integrated LED circuit board within the sealed rear light assembly develops cracks or faulty connections, most commonly at a specific solder point or thin metal connector plate. This disables one or both tail and brake lights. The failure is sometimes intermittent—tapping or bumping the assembly temporarily restores function before the lights fail again. Owners report both sides can fail independently or simultaneously.
When: Typically 3–5 years of ownership; failures documented between 41,000–80,000 miles; some occur as early as 19 months of use.
Symptoms owners cite: Rear brake light inoperable when pedal depressed; Tail light fails to illuminate; Turn signal and hazard lights may work while brake/tail lights do not; Intermittent operation; tapping on assembly briefly restores function; Both driver and passenger sides affected; Failure occurs while parked, during motion, or while turning; No warning to driver until notified by following motorists or police stop
Repairs/costs cited: Full sealed assembly replacement required; no user-replaceable bulbs. Dealership quotes: $650–$1,112 per assembly (some include labor/installation). Aftermarket replacements available at ~$800–$1,000. Independent shops report fixes via melting plastic housing to access and solder the circuit board, but this is temporary. Parts noted as being on backorder at dealers.
Recalls/TSBs owners mention: GMC issued a recall on 2015–2016 GMC Yukon taillights for the same defect but has not extended it to 2017+ models despite identical parts and failures. One owner reports a 'service bulletin' covered one assembly replacement. Most owners report GM denies warranty coverage, claims it is not a safety issue, or states they have no knowledge of the problem. Dealers report awareness of multiple Yukon owners with identical failures but offer no remedial program.
Sealed light assembly design: non-serviceable, premature LED failure
The rear light assembly is a sealed integrated unit with no user-replaceable bulbs or components. LED strips within the circuit board fail prematurely—well before the typical 5,000+ hour lifespan of modern LED technology. Owners who work in LED lighting note that 3–5 years of intermittent driving should not exhaust LED life, indicating either defective LEDs or the circuit board design accelerates degradation.
When: 3–5 years of normal ownership; some as early as 19 months.
Symptoms owners cite: LEDs stop emitting light entirely; LED strips within assembly go dark; No gradual dimming; sudden failure; Both assemblies may fail within one year of each other
Repairs/costs cited: Assembly must be fully replaced ($650–$1,112 per side). Owners note the sealed design prevents any DIY repair or inspection.
Recalls/TSBs owners mention: None documented specific to LED lifespan. GM's recall of 2015–2016 models addresses the same assembly type but is not extended to 2017 Yukons.

What owners are reporting 3 most recent
My tail light is faulty. It is working some, shorts out, stops working, I hit a bump, it starts working again. Almost caused a crash, the lady followed me to the store to tell me it was out. Took it to the mechanic and it was working again without any repair. Does this everyday.
Pulled over by police for malfunctioning lhr brake light. Entire rear lamp assembly must be replaced since it is an integrated circuit board with LED lamps. $700 plus installation. Several victims on-line discussion forums.
Tail and brake light no longer working
Common questions
How serious is the lighting problem on the 2017 GMC Yukon?
It's a documented issue but not catastrophic. 44 complaints have been filed. Repairs average $250 and most owners catch it before it causes a breakdown.
At what mileage does the lighting typically fail?
Across the 17 complaints that reported odometer mileage, most lighting failures cluster between 40,000 and 60,000 miles, with the median around 53,570. A quarter of owners report trouble before 40,000; a quarter make it past 60,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $250 for lighting repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to lighting?
No active recalls currently cover lighting issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
