Among the 11 model years of Hyundai Sonata in our records for seatbelts problems, this one ranks #3 by owner-complaint volume.
The failure pattern owners describe
Buyer takeaway: Owners of 2012 Hyundai Sonatas report persistent seat belt buckle failures requiring multiple attempts to latch, and spontaneous unbuckling while driving—serious safety issues with NHTSA Campaign 17V152000 partly addressing the problem. Expect dealer charges of $300–$500 for buckle replacement, and verify any prior recall work was actually completed.
Drivers report the seat belt buckle on the driver's side—and occasionally the passenger side—routinely fails to catch the latch. Owners describe needing 3 to 8+ attempts to get the buckle to click into place, and some say it won't engage at all. The buckle sometimes pops back out after seeming to latch, forcing repeated fiddling with the metal clip. One owner at 11,000 miles had a front passenger buckle failure; others reported issues at 85,000, 90,000, 127,000, and 150,000 miles. One complaint surfaced in late 2022 on a vehicle purchased new in 2012.
A separate and more serious failure: the seat belt spontaneously unbuckles while driving at various speeds, without warning or driver action. This has happened on multiple occasions for affected owners, creating an uncontrolled safety hazard during operation.
Rear seat belts on at least one vehicle show visible fraying and tearing through about half the belt width near the top, where the belt exits the retraction assembly.
NHTSA Campaign 17V152000 (seat belts) is associated with this model year. Some dealers deny failures are covered under that recall or charge $160 inspection fees to determine eligibility. Replacement costs range $337–$484 at dealerships. One owner reported a recall performed in December 2017, though no documentation was provided and the complaint continued.
