Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering seatbelts 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 informational bulletin provides information to advise dealers about seat belt buckles not operating and/or seat belt warning light illumination, as well as difficulty latching and unlatching the buckle or the buckle release button sticking.

The failure pattern owners describe
Owners of the 2007 GMC Yukon report several distinct seatbelt failures that raise safety concerns. The most serious involves third-row seatbelts locking up during vehicle motion, immobilizing occupants and restricting breathing—one owner stated her child cries and cannot breathe when the belt locks, forcing highway pullovers. One child suffered arm and chest bruising when a belt retracted unexpectedly during removal from a car seat.
Front and rear buckles frequently fail to latch. Owners describe female receptacles refusing the male end, seizure of internal components preventing proper engagement, and buckles that simply won't click into place. Some belts lock inappropriately, leaving drivers stuck and unable to drive safely; others spontaneously unlatch without being touched—while driving or parked.
Third-row belts are reportedly too short for adult occupants, and the ratchet mechanisms malfunction, forcing improper seating positions. One owner noted the vehicle markets third-row adult seating but provides inadequate space and belts, pressuring occupants to skip seatbelt use entirely.
Dealers told owners the belts met safety standards and refused repairs. One owner paid $95 out-of-pocket for a replacement buckle. GMC referred complaints to NHTSA rather than addressing the defects.
Failure modes owners describe
Third-row seatbelt excessive locking during vehicle motion
Third-row seatbelts lock up or jam during normal driving, restricting movement and breathing of occupants, particularly children in car seats. Owners report belts locking the child in place, requiring pullover to manually retract.
When: During vehicle operation; one report at 300 miles
Symptoms owners cite: Belt locks during motion, restricting occupant movement; Child cannot breathe or move freely in car seat; Requires manual full retraction to unlock; Child crying and distress reported
Repairs/costs cited: No repairs documented; dealer referred complaint to NHTSA
Seatbelt fails to lock or secure when buckled
Front and rear seatbelts fail to latch or lock when buckled. Female portion seizes or refuses to accept male buckle portion, or male portion fails to click and secure.
When: Various mileages: 78,000 miles and 205,000 miles reported
Symptoms owners cite: Buckle fails to click or secure; Female receptacle will not accept male end; Male portion will not engage properly; Repeated failure to latch
Repairs/costs cited: Not repaired in reported cases; one owner paid $95 for replacement part and self-repaired
Recalls/TSBs owners mention: Dealer stated belts were within safety standards; one dealer refused repair under warranty
Seatbelt spontaneously unlatches or retracts
Buckle unlatches or disconnects on its own without being touched while driving or parked. Seatbelt retracts suddenly, causing injury to occupants being removed from seats.
When: At 85,000 miles and during normal operation
Symptoms owners cite: Buckle releases without user input; Occurs while driving or stationary; Sudden retraction causing bruising to arm and chest; Repeated intermittent failure
Repairs/costs cited: One case resulted in bruising to child's arm and chest during removal from car seat
Third-row seatbelt insufficient length and ratchet malfunction
Third-row seatbelts are too short for adult occupants and ratchet mechanism does not operate properly, forcing occupants into improper seating positions and encouraging seatbelt non-use.
When: Inherent design issue; noted at vehicle purchase
Symptoms owners cite: Belt length insufficient for adults; Ratchet mechanism inoperative; Inadequate legroom and shoulder room forces improper seating; Encourages deliberate seatbelt avoidance by occupants
Seatbelt buckle jam or obstruction requiring button depression
Seatbelt female receptacle either will not accept male end or requires depression of release button to engage, indicating internal obstruction or design defect.
When: At normal use
Symptoms owners cite: Female receptacle refuses male end without button depression; Evidence of missing internal piece in buckle; Cannot insert belt into buckle normally
Repairs/costs cited: One complaint mentions missing internal piece in buckle
