# Other 24B27

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

In affected vehicles, the Variable Displacement Oil Pump \(VDOP\) delivers oil to the engine at low pressure/capacity during idle conditions. Routine occurrences of prolonged idle time may result in excess wear to the engine camshaft lobes and valve tappet surfaces due to reduced lubrication. Over time, the engine may progressively run rough due to cylinder misfire. Additionally, customers may hear engine tapping noises and the Check Engine Light \(CEL\) may illuminate.
