Rear subframe corrosion has put 880,514 Hondas and Acuras under recall

Rust is working its way through the rear subframes of 880,514 Honda and Acura SUVs and pickups sold in the snowbelt, and the failure it can end in is a suspension arm letting go. American Honda’s recall covers 2016-2022 Honda Pilot, 2017-2023 Honda Ridgeline, 2019-2023 Honda Passport and 2014-2020 Acura MDX vehicles, all of them in one campaign in the federal record. The count keeps showing up in running recall tallies, but the dates attached to it trace back to the spring of 2026.

The recall does not cover the whole production run of those four models. Only vehicles sold in 22 states and the District of Columbia where winter road salt is routine are included.

One campaign, four models, 880,514 units

The figure belongs to NHTSA campaign 26V365. The agency’s recall database entry lists 880,514 potentially affected vehicles and describes the defect in a single sentence: the rear subframe may corrode at the suspension mounting points, which can result in rear suspension component failure. Its consequence statement adds that a failed part such as the rear control arm can cost the driver handling and control, which raises the odds of a collision.

TFLcar’s breakdown shows how the total divides. The 2016-2022 Pilot accounts for 463,253 units, more than half the campaign, and the 2014-2020 MDX for 217,517. The Passport and Ridgeline make up the remaining 200,000 or so. The affected vehicles were built between April 2013 and January 2023, so the oldest MDX examples have been through a dozen winters.

The states covered are Connecticut, Delaware, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia and Wisconsin, plus Washington, D.C. Vehicles sold elsewhere in the country fall outside the recall population, because the corrosion mechanism depends on de-icing salt.

The geographic limit comes straight from the failure mechanism. The Part 573 report describes premature corrosion in salt-belt regions, and the NHTSA database entry confines the population to the states named above, so the campaign is defined by where road salt does its work on a subframe whose paint has already started to peel, not by model year alone, and the filing counts road salt as part of the cause.

A coating specification and a Georgia supplier

Honda’s own filing, the Part 573 safety recall report, traces the corrosion to “improper coating specifications.” The rear subframes left the factory without enough pre-paint treatment or coating thickness, so paint adhered poorly and began to peel near the weld areas of the arm brackets. Once bare metal meets de-icing salt, the steel thins at the mounting points until too little remains to hold the suspension in place.

Wards Auto reported that the subframes came from a Georgia supplier, F&P Georgia, which improved its pre-paint treatment in August 2022 and then increased coating thickness in January 2023. That timing lines up with the end of the affected build window. The replacement parts in the remedy carry the improved pre-paint treatment and the thicker coating, and dealers install a reinforcement kit on subframes they inspect.

Honda also estimates that about 1 percent of the recalled vehicles will actually develop the defect. Applied to 880,514 vehicles, that is roughly 8,800 vehicles with the defect itself, set against the far larger group inspected as a precaution.

A 2021 paint finding and a May 2026 decision

The timeline in the Part 573 report is long. Honda identified a difference in paint quality in December 2021. The first failure report arrived on September 5, 2025, from Canada, almost four years later. The recall decision came on May 28, 2026, dealers were notified on June 5, and owner letters began on July 7. The Associated Press story circulated on June 10, and local stations carried it as a loss-of-control warning. Four years of monitoring separate the December 2021 finding from the decision, according to TFLcar’s account of the filing.

Honda told NHTSA it had logged zero warranty claims in the United States through May 21, 2026 tied to the problem, so the recall rests on one reported failure in Canada and an engineering finding about the coating rather than a pattern of U.S. breakdowns, a distinction that explains why the filing reads as a precaution built on the supplier’s paint history and the behavior of steel under salt.

Recall trackers have since folded the campaign into running annual totals. The Car Dealership Guy automaker recall tracker lists Honda and Acura at 880,514 for 2026 and describes the vehicles as salt-belt only, with an improperly coated subframe that may corrode prematurely. The tracker dates the entry to June 2026, matching the NHTSA record, and not to October.
