Also, dealers are to ensure the oil level plug is tightened to Kia’s factory specifications upon the completion of the inspection and necessary repair. The oil level plug in the subject vehicles may not have been installed properly during assembly. The oil level plug may be loose or detached from the 8-speed Automatic Transaxle (A/T) which may result in leaking automatic transmission fluid (ATF). A transaxle which is operated with excessively low ATF may become damaged over time.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.
