Honda has issued a recall for 880,514 vehicles across four model lines: the Pilot, Passport, Ridgeline, and Acura MDX.Only vehicles sold in certain states are included, specifically states that experience cold, snowy winters and use salt to keep the roads clear, such as Michigan, New York, and Pennsylvania.The recall is focused on the rear subframe, which can rust more quickly than expected due to improper coating in the manufacturing process, potentially leading to suspension failure.
