## NHTSA's summary

This owner notification letter informs owners that Cummins Inc. has launched a campaign that may affect their X15 engine\(s\). The subject engines may not be meeting emissions requirements because of an incorrect SCR catalyst unit which may cause elevated NOx and ammonia emissions from the tailpipe.
