Service bulletin WTY030_TSB_R1

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

TECHNICAL SERVICE BULLETIN: HALOGEN HEADLAMP REPLACEMENT - This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides information associated with the 'Halogen Headlamp High Beam Warranty Extension Program' (WTY030) to replace the affected (left and/or right side) headlamp assembly on certain 2020MY Telluride (ON) LX/S/EX vehicles, produced at Kia Georgia from January 09, 2019 through November 18, 2019, which may exhibit a loss of high-beam functionality. Due to an internal failure in the headlamp, the high beam lights may not illuminate when turning the light switch from the low to high beams. The low-beam function is not affected. The vehicle’s warranty for this issue will be extended from 5 years/60,000 miles to 15 years/150,000 miles, whichever comes first, starting from the date the vehicle was first put into service.
