Having touched upon the technical stuff, let's get into why the folks at Honda issued a recall for 248,999 vehicles produced for the 2015 through 2019 model years. According to the document attached below, the improper settings of the equipment used to manufacture the crankshaft of the J35Y6 may lead to connecting rod bearing seizure. More specifically, the crank pin was improperly ground, resulting in pins with an out-of-spec crown or convex shape.
Abnormal engine noise is the easiest way of telling that something is wrong with the J35Y6. Other indications come in the form of stalling, the inability to restart the engine, decreased engine output, and engine check lamp illumination. As per the cited safety recall report, the iffy cranks in question bear part numbers 10002-5J2-A00 and 10002-5J6-A01.
The Japanese automaker told the National Highway Traffic Safety Administration that the first market complaint over this issue was filed with American Honda Motor Co. in February 2020. A whopping 1,450 warranty claims were submitted in the period between July 2014 and November 2023, which indicates that Honda was aware of said problem before the market complaint from February 2020.
Based on documents published by the federal watchdog, affected TLX vehicles were manufactured between February 2014 and July 2020. The MDX is affected as well, namely crossovers produced from June 2016 through March 2020. The Pilot is listed with build dates beginning May 2016 and ending June 2016. The Odyssey is listed from April 2018 to August 2018.
Moving on to the Ridgeline pickup, the 2017 and 2019 model years are affected. There's no mention of the 2018, though. Similarly, there is no mention of the Passport, which is best described as the two-row sibling of the family-sized Pilot mid-size crossover.
