# Service bulletin 26\-EM\-015H TSB

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 11038456
- Published by NHTSA: 2026\-10\-13
- Manufacturer's number: 26\-EM\-015H TSB
- Manufacturer's date: 2026\-10\-07
- NHTSA component: ENGINE

## NHTSA's summary

Certain vehicles equipped with internal combustion engines may exhibit higher\-than\-expected engine oil consumption. This bulletin provides the inspection and repair procedures for vehicles exhibiting this condition. All internal combustion engines consume engine oil as part of normal engine operation. Oil consumption rates may vary based on mileage, operating conditions, driving habits, and maintenance history. Hyundai recommends following the prescribed maintenance schedule and periodically checking the engine oil level using the dipstick to maintain proper engine oil level.
