Manufacturer summary

Original wording in English

Some Santa Fe (MX5A) and Santa Cruz (NXT) vehicles may exhibit a low idle or excessive vibration while in Drive or Reverse, or DTC P050600 (Idle Air Control System – RPM Lower than Expected) caused by the one-way clutch sprags being misaligned. This bulletin provides instructions to remove the automatic transmission and replace the torque converter.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
