Three original equipment Hankook Dynapro HT tires developed belt-related failures at approximately 6,000 miles of use during a road trip in June 2026. On [XXX], while driving in Tennessee, we noticed a vibration that gradually increased in intensity. We stopped for inspection at C&D Tire & Service in Athens, TN, which found a "bad belt" in the left-front tire at an odometer reading of 5,649 miles. The tire was replaced and retained. The following day, [XXX], the vibration returned and worsened. We stopped at Bill Morgan Tire in Lexington, KY, which found a "severe belt rupture" in the left-rear outer tire and noted that the right-front original equipment tire was "showing signs" of a similar condition. The work order noted all five removed tires had a little over 6,000 miles of use and approximately 12/32" tread remaining. The worst of the tires was retained. Two independent tire dealers, in two different states, identified belt-related abnormalities in three original equipment tires within approximately 24 hours. Given that we were hundreds of miles from home and continuing on interstate highways, we replaced all remaining tires for safety. We have retained two of the removed tires, which show visible belt deformity, and they are available for inspection. No crash, injury, or loss of vehicle control occurred; the vibration was noticed and addressed before any tire failed catastrophically while underway.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
