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.

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.
