full bulletin at NHTSA ↗Service Bulletin - Due to high demand for repairs under this warranty extension, pistons and rings required to complete this repair are currently backordered.

full bulletin at NHTSA ↗Dealer Message - On January 16, 2019, Acura announced a warranty extension for certain 2009-14 Acura vehicles equipped with a 3.7L V6 engine to address client concerns related to excessive oil consumption. Acura extended the powertrain warranty coverage to address engine issues related to excessive oil consumption from the original 6 years/70,000 miles to 8 years/125,000 miles, whichever comes first. In addition, all vehicles were provided a grace period until August 31, 2019 and were covered regardless of time in service or mileage.

These deposits restrict the ring's ability to scrape and return oil from the cylinder wall to the crankcase, which can result in excessive engine oil consumption that may exceed client expectations.
