Official summary
Some customers may complain that the A/C is not cold enough. Upon inspection, a refrigerant leak (1) from the A/C hose (LO) (2) is confirmed. This may be caused by foreign material present on the block side at the A/C hose (LO) connection point. To eliminate this concern, an inspection process for foreign materials was added to the parts manufacturing process as a temporary measure. A permanent measure is under study.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
