Official summary

The new logic addresses customer concerns of inconsistent shifting characteristics and / or a ?slipping? -type sensation which may be experienced under moderate acceleration after a cold start before the CVT is up to operating temperature.
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.
