# Service bulletin 23\-01\-076H

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.

## NHTSA's summary

Some Santa Fe \(CM\) vehicles may have an engine that potentially leaks oil from the front cylinder bank’s valve cover onto the alternator. Oil could damage the alternator resulting in illumination of the charging system warning lamp and disablement of the charging system. If the vehicle is continually driven without recharging the battery, the engine will eventually shut off, increasing the risk of a crash. This bulletin outlines the procedures to inspect for T\-joint leakage and install an oil protector to address this issue. The service procedure contained in TSB 23\-01\-076H \(or latest version\) is summarized below: 1. If the alternator voltage is less than 14.0V and there is evidence of oil leak at the T\-joint, replace the alternator, valve cover gasket, and install the oil protector. 2. If the alternator voltage is greater than 14.0V and there is evidence of oil leak at the T\-joint, replace the valve cover gasket and install the oil protector. Do not replace the alternator. 3. If the alternator voltage is greater than 14.0V and there is no evidence of oil leak at the T\-joint, install the oil protector. Do not replace the valve cover gasket or the alternator.

- [26\-EM\-016H TSB](/bulletins/11038458.md), 2026-10-14, Service bulletin: ENGINE. Some vehicles equipped with internal combustion engines may exhibit higher\-than\-expected engine oil consumption. This bulletin outlines the combustion chamber cleaning procedure for vehicles diagnosed with this condition. All internal combustion engines consume some engine oil during normal operation, depending on driving conditions and mileage, and this procedure should only be performed when deemed necessary based on inspection and diagnosis of the vehicle as outlined in TSB 26\-EM\-015H, Engine Oil Consumption – Inspection \& Repair Guidelines, or the latest revision.
- [26\-EM\-015H TSB](/bulletins/11038456.md), 2026-10-13, Service bulletin: ENGINE. 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.
