Honda extends Accord, CR-V warranty over fouled piston rings

Honda has issued an extended warranty program for the 2008-2011 Accord and 2010-2011 CR-V, providing a free fix for an issue that affects the four-cylinder packages.

The engine is prone to experience excessive oil consumption under certain circumstances that create deposits on the piston rings. The rings can degrade if the engine is regularly put through hard acceleration while cold and with low-quality gasoline.

“All these conditions happening at the same time are rare, but if they do occur, deposits may form over years of driving under these conditions,” the service bulletin notes. “If the oil control rings begin to stick because of the deposits, the customer may subsequently complain about excessive oil consumption.”

Service technicians are instructed to perform an oil consumption test to determine if the engine is consuming an unusually high amount of oil. If so, the company will replace all of the pistons and even the engine block if it has also been damaged.

The problem was first detailed in a service bulletin dating back to 2013, however Honda has now decided to extend the engine warranty for both models to eight years or 125,000 miles, according to Consumer Reports. Abnormal consumption is said to be one quart every 1,000 to 3,000 miles.
