Service bulletins for the 2022 Hyundai Tucson

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.

Bulletins, newest first
22-AT-010H2022-08-24. Service bulletin. POWER TRAIN; ENGINE AND ENGINE COOLING. If you are servicing an applicable vehicle with a “Check Engine” light on and one or more of the DTC listed below, follow the Service Procedure and replace the valve body internal harness and the input/output speed sensor.
22-HC-002H2022-08-24. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. This bulletin addresses a warning light “Refill Inverter Coolant” displayed on the instrument cluster, but inspection of the under hood blue coolant reservoir is found to be at normal level (not below “MIN” marking on the reservoir bottle). This may be caused by poor flow of antifreeze inside the low-conductivity coolant pipe from internal debris, resulting in unusual high EWP operation being detected. Follow the procedure outlined in this bulletin to flush/discharge debris from the cooling system and replace the blue coolant. To effectively resolve, the flushing must be performed section by section as instructed. After flushing of the cooling system is done, updated BSC-2 coolant will be installed.
