Manufacturer summary

Original wording in English

Certain Elantra (ADA) vehicles may have been incorrectly updated with Cylinder Noise Detection System (CNDS) software that can set DTC P132700; this software was intended only for Korean-built Elantra (AD) vehicles. In addition, the California Air Resources Board has determined that these vehicles may be releasing air pollutants which exceed Federal and California standards.

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.
