Honda is recalling more than 880,000 vehicles in the United States because rear suspension components can corrode and fail, increasing the risk that drivers could lose control. The recall affects some of Honda and Acura’s most familiar family and utility vehicles, including the Honda Pilot, Honda Ridgeline, Honda Passport, and Acura MDX.
According to the Associated Press, the recall covers 880,514 vehicles and is focused on vehicles sold or registered in salt-belt states where winter road salt can speed up corrosion. The National Highway Traffic Safety Administration campaign number is 26V367000, and Honda’s internal recall numbers are AOU and AOT.
This is not a cosmetic rust issue. The problem involves the rear subframe, where suspension components attach to the vehicle. If corrosion progresses, the rear suspension can fail, which may affect handling, stability, braking, and control.
Which Honda and Acura Models Are Affected?
The recall covers certain 2016 through 2022 Honda Pilot SUVs, 2017 through 2023 Honda Ridgeline pickups, 2019 through 2023 Honda Passport SUVs, and 2014 through 2020 Acura MDX SUVs.
These are high-volume family vehicles. Many are used for commuting, school runs, road trips, towing, winter driving, and everyday hauling. That makes the recall important because the affected vehicles are not rare specialty models. They are common vehicles still widely used by families across cold-weather states.
Owners should not rely only on model name and year to determine whether their vehicle is included. The safest step is to check the vehicle identification number through the NHTSA recall lookup tool or contact Honda or Acura customer service.
Why Salt-Belt States Are the Focus
The recall is limited to vehicles in states where road salt is commonly used during winter. Salt helps melt ice and improve winter road safety, but it can accelerate rust when it collects on exposed metal parts under a vehicle.
The recall includes vehicles sold in Connecticut, Delaware, the District of Columbia, 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, according to the AP report.
These regions are often called salt-belt states because winter weather creates regular use of de-icing agents. Vehicles driven in those conditions may face years of salt exposure, moisture, freeze-thaw cycles, slush, and road grime. If a protective coating is weak or damaged, corrosion can spread faster than expected.
What Is the Rear Subframe?
The rear subframe is a structural part of the vehicle that helps support rear suspension components. It provides mounting points for arms, links, and other parts that keep the wheels aligned and controlled.
Drivers do not normally see or think about the rear subframe because it sits underneath the vehicle. But it is essential to ride quality, stability, wheel alignment, braking behavior, and handling.
If the mounting area corrodes, the metal can thin, crack, or weaken. That can allow suspension parts such as a rear control arm or lower arm to shift, loosen, or fail. Autoblog reported that Honda said de-icing agents can contribute to premature corrosion at rear subframe suspension mounting points, potentially leading to wheel misalignment or inadequate wheel retention.
Why the Defect Can Raise Crash Risk
A suspension system is designed to keep tires planted and aligned with the road. If a rear suspension component fails, the rear wheel may move out of its intended position. That can affect steering response, braking stability, cornering, and the vehicle’s ability to track straight.
The Reuters report on the recall said rear suspension component failure, including the rear control arm, could lead to loss of handling and control, increasing the risk of a crash or injury.
This is why the recall should not be ignored even if the vehicle currently drives normally. Corrosion often develops out of sight and may not cause obvious symptoms until the part is already weakened.
What Caused the Problem?
The defect is linked to premature corrosion of the rear subframe. Car and Driver reported that the issue involves improper coating on the subframes, which can lead to weak paint adhesion and early paint peeling around the arm bracket welds. Once the protective coating fails, exposed metal becomes more vulnerable to rust, especially in areas where road salt is common.
That means the issue is not simply that old vehicles rust. Rust is expected in some form on vehicles that spend years in harsh winter climates. The recall concern is that the affected components may corrode prematurely in critical suspension mounting areas.
When corrosion affects a structural mounting point, the risk moves from appearance to safety.
Honda Estimates Only a Small Percentage Have the Defect
Honda estimates that about 1% of the recalled vehicles may have the defect. That may sound small, but 1% of 880,514 vehicles still represents thousands of possible vehicles with a dangerous condition.
Also, recalls are preventive. Manufacturers often recall a broader population because they cannot know which individual vehicles have developed the problem without inspection. Two vehicles built in the same period may have very different corrosion levels depending on winter exposure, parking conditions, underbody washing, mileage, and local road treatment.
If your vehicle is included, it should be inspected even if it feels fine.
Honda Has Reported No Injuries or Deaths
Honda said it had received no reports of injuries or deaths related to the issue, and AP reported that Honda had no warranty claims tied to the problem at the time of the recall.
That is good news, but it does not make the recall optional. Safety recalls are often issued before a serious injury occurs. The goal is to find and repair the defect before a driver loses control or a suspension component fails on the road.
A recall without injuries is still a recall. It means the company and regulators identified a risk that needs correction.
What Dealers Will Do
Honda and Acura dealers will inspect the rear subframe. If necessary, they will install a reinforcement kit. If the corrosion is more serious, dealers will repair or replace rear subframe components at no cost to owners.
The repair path depends on the vehicle’s condition. A vehicle with limited corrosion may need reinforcement. A vehicle with more severe corrosion may need larger repairs or replacement components.
Owners should not attempt to weld, patch, coat, or reinforce the rear subframe themselves as a substitute for the official recall remedy. Suspension mounting points are safety-critical, and the repair should be handled through Honda or Acura’s authorized recall process.
When Owners Will Be Notified
Owner notification letters were expected to begin mailing on July 7, 2026. Vehicle identification numbers connected to the recall were expected to be searchable on NHTSA.gov beginning June 10, according to the AP report.
Owners do not need to wait for a paper letter if they are concerned. They can check the VIN through NHTSA’s recall lookup system or contact Honda customer service at 1-888-234-2138. Acura owners can also contact Acura customer support or an authorized Acura dealer.
Because vehicles can change owners, used-vehicle buyers should also check recall status before purchase. A recall notice may have been sent to a previous owner or outdated address.
Why Used-Car Buyers Should Pay Attention
The affected models are popular used vehicles. A used Pilot, Ridgeline, Passport, or MDX may look like a practical purchase, especially for families looking for a three-row SUV, pickup, or midsize crossover. But in salt-belt states, underbody corrosion should always be part of the inspection.
Before buying one of the affected models, shoppers should check the VIN, ask for recall repair documentation, and have the underbody inspected. A vehicle may have an open recall even if it appears clean from the outside.
Used-car shoppers in northern states should be especially careful with vehicles that have spent years on salted roads. Rust can hide under plastic covers, suspension mounts, brackets, and frame areas.
What Warning Signs Drivers Should Watch For
Drivers should pay attention to unusual rear-end noises, clunking, rattling, changes in alignment, steering pull, unstable handling, rear-wheel wobble, uneven tire wear, braking instability, or a vehicle that feels different over bumps or turns.
These symptoms do not automatically mean the recall defect is present, but they are warning signs that the suspension or underbody needs inspection. A suspension issue should not be ignored, especially in a vehicle included in a corrosion-related recall.
If a vehicle feels unstable or makes loud clunking noises from the rear, drivers should avoid long trips and schedule service promptly.
Why Underbody Rust Is Hard to Judge From the Outside
A vehicle can look clean on the outside while rust develops underneath. Paint, body panels, and interior condition do not necessarily reveal what is happening on suspension mounts, subframes, brackets, fuel lines, brake lines, and exhaust hangers.
This is why lift inspections matter. A technician can inspect underbody components, probe suspect areas, and compare corrosion with repair criteria.
Owners in salt-belt states should consider regular underbody inspections even outside recalls, especially once vehicles reach five to ten years old. Early rust treatment and cleaning can help, but structural corrosion needs professional evaluation.
Washing Helps, but It Is Not a Recall Fix
Regular underbody washing can reduce salt buildup, especially after winter storms. It can help slow corrosion by removing salt, sand, and brine from hidden areas. Parking in dry areas and keeping drain holes clear may also help.
However, washing does not repair a defective coating or restore metal that has already thinned. If a vehicle is included in the recall, the official inspection and repair are still necessary.
Owners should treat washing as prevention, not as a replacement for recall service.
Why Salt Brine Can Be So Aggressive
Many winter states use liquid brines, salt mixtures, and chemical de-icers before and during storms. These treatments can cling to underbody surfaces and seep into seams, welds, brackets, and crevices.
Salt accelerates electrochemical corrosion by helping water conduct electricity between metal surfaces. When protective paint or coating peels, cracks, or fails, corrosion can start and spread.
This is why vehicles in salt-belt areas often face higher corrosion risk than similar vehicles in dry or warm climates. The same model can age very differently depending on where it has been driven.
Why Suspension Recalls Are Different From Minor Defects
Some recalls involve labels, software settings, lamps, or non-structural parts. Those recalls still matter, but suspension recalls deserve special attention because they affect the vehicle’s contact with the road.
The suspension controls wheel position. When it fails, the driver may have little time to react. At highway speed, a rear suspension failure could cause sudden instability. During braking or turning, the risk can be even greater.
This is why Honda’s recall remedy involves inspection, reinforcement, repair, or replacement instead of a simple warning sticker.
What This Means for Honda’s Reputation
Honda has long had a reputation for durability and reliability. That reputation is one reason used Hondas and Acuras often hold value. A major corrosion recall involving nearly 900,000 vehicles can therefore attract attention because it touches older vehicles that many owners expected to last a long time.
At the same time, issuing a recall before injuries are reported can be seen as responsible safety action. The key question for owners will be how quickly dealers can inspect and repair vehicles, especially in states where many affected models are on the road.
A large recall can strain dealer schedules. Owners should contact dealers early rather than waiting until service bays are fully booked.
Why This Recall Is Especially Important for Families
The affected vehicles are often used by families. Pilots and MDXs carry children, groceries, pets, sports equipment, and road-trip luggage. Ridgelines may carry tools, trailers, outdoor gear, and weekend loads. Passports are often used for commuting and travel.
A rear-suspension failure in these vehicles could put not only the driver but passengers and other road users at risk. That makes recall completion especially important.
Families should not assume that because a vehicle has been reliable for years, it can skip inspection. Corrosion can progress quietly until the mounting area is weakened.
What Owners Should Do Now
Owners should check their VIN through NHTSA or Honda, schedule a dealer inspection if included, and avoid delaying the recall repair. They should also listen for unusual rear suspension noises and pay attention to changes in handling.
If the vehicle is frequently driven in winter conditions, parked outdoors, used on rural salted roads, or has visible underbody rust, the inspection becomes even more urgent.
Owners should keep repair documentation after the recall work is completed. That record can help with resale, insurance questions, and future service history.
Final Takeaway
Honda is recalling 880,514 vehicles in salt-belt states because rear subframe corrosion can cause rear suspension components to fail, increasing the risk of loss of control, crashes, or injuries. The recall covers certain 2016–2022 Honda Pilot, 2017–2023 Honda Ridgeline, 2019–2023 Honda Passport, and 2014–2020 Acura MDX vehicles.
The problem is linked to corrosion at rear subframe suspension mounting points, where road salt and weak protective coating can allow rust to weaken critical metal areas. Dealers will inspect affected vehicles and, if needed, install reinforcement kits or repair or replace rear subframe components free of charge.
Owners in affected states should check their VIN, schedule recall service, and not ignore symptoms such as rear clunking, wobble, alignment changes, or unstable handling. A rust issue under the vehicle may be easy to miss, but when it involves suspension mounting points, it becomes a serious safety concern.
