Affected Component: ENGINE AND ENGINE COOLING
- Summary
- Owner Notification Letter - On certain 2009-14 Acura vehicles equipped with the 3.7L V6 engine, the oil control rings may become clogged with carbon deposits during normal engine operation. These deposits restrict the control ring's ability to return oil from the cylinder walls to the crankcase, resulting in excessive engine oil consumption.
