I recently bought a used 2012 Acura MDX to replace
I recently bought a used 2012 Acura MDX to replace a 2007 MDX. Had high expectations for the car until the first 2000 miles passed. - THEN the Check Oil at dealer warning came on. Very long story short. Thought at first the prior owner had not serviced the oil and engine properly - but NO - the engine is well-known by owners and Acura to have a defect in the ring/cylinder design that causes a VERY high oil consumption. Like a quart every 1000 miles. Acura issued a Technical Service Bulletin in July 2016 about dealers providing "goodwill consideration" in trying to appease irate owners. Long story short: They changed the engine design to have a certain aluminum coating in the cylinders - and the rings wear out from abrasion with the finished cylinder. There are attempts at getting a class-action lawsuit by a legal firm - and not sure where that will end up - but I've already registered with the law firm. The J37A engine is the consistent problem - in other Acura models as well. Solution: trade the car or replace the engine. Not a pretty picture. So I am trading ASAP. Heavier oil than the recommended 5W-20 could cause far greater issues in the engine. Statistics are showing that over 11% of the J37A engines have SEVERE oil consumption issues - rumor has it that rings were installed incorrectly at the factory. My 2007 MDX had a different version of the engine and never used oil. They changed to the J37A in 2008 and continued with it through at least 2014. I have no idea how reviewers have missed this - especially Consumer Reports. Acura is claiming it is normal to add a quart of oil at 1000 miles. Right...!
