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.

The failure pattern owners describe
Owners describe seven distinct seatbelt problems in this 2011 Sonata cluster. The most common complaint is latching failure: buckles don't engage fully, require multiple attempts to hold, or pop free when pulled. Several owners report seatbelts that refuse to retract, locking in extended position or failing to wind back after use; one owner says a dealer has no extension solution available.
Detachment from mounting hardware shows up repeatedly. In one verified accident case, a driver-side seatbelt disconnected entirely from the door panel, leaving the occupant unprotected and injured. A passenger seatbelt unlatched from the floor connector during normal use. In another case, the latch buckle dented the door sensor, preventing the vehicle from starting.
Spontaneous unbuckling while driving is documented in multiple complaints. One describes both front seatbelts releasing mid-drive; another shows a child's seatbelt unbuckling during an acceleration event.
Two owners report serious injury from seatbelt pretensioner malfunction during collisions—one case documents a fractured jaw, another includes acute hernia, chest and abdominal injuries requiring surgery and breast tissue damage.
One owner reports the belt locks up whenever leaning forward. Another sees a persistent seatbelt warning light that won't clear. Several owners mention recalls (NHTSA 17V617000 and 18V137000) but state dealers either refused repair or claimed dealers had no solution available.
