Warranty extension 26-SS-001H TSB

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Certain Palisade (LX2) vehicles may exhibit a clunking or thumping noise from the rear of the vehicle while driving over rough roads. This may be caused by worn self-leveling rear shock absorbers. Hyundai is extending the warranty coverage for the self-leveling rear shock absorbers to 10 years/120,000 miles from the date of original retail delivery or date of first use (whichever occurs first) and is valid for original and subsequent owners. Follow the procedure in the bulletin to identify the source of the noise, and if necessary, replace one or both self-leveling rear shock absorbers. Please note that for the first repair, replacement of both rear shock absorbers will be covered by this warranty extension. For subsequent repairs, one or both rear shock absorbers will be covered depending upon the impacted side(s).
