## Other bulletins for the same vehicles and component

- [TXXZ OL](/bulletins/11014615.md), 2025-03-01, Warranty extension: POWER TRAIN. Certain 2014 – 2015 model year Tucson vehicles may have a weakened weld at the zone where the center muffler is attached to the exhaust pipe. This condition may cause the center muffler to detach from the exhaust pipe. At Hyundai, we are committed to providing vehicles of outstanding quality and value. In an effort to meet this commitment, Hyundai is extending the warranty coverage for the center muffler assembly under this condition to 15 years / 150,000 miles from the date of original retail delivery or date of first use and is valid for original and subsequent owners.
