Descriptive Information to include

• The basis for how the recall population was determined and
• How the recalled products differ from products that were not included in the recall

Enter descriptive information:
The recall population was determined based on manufacturing records. The production range reflects all possible vehicles that could experience the problem. The recall is specific to vehicles sold in Canada.

Number potentially involved in Canada: 136,260

Estimated percentage of involved with defect: 1%

Describe the defect or noncompliance:
Vehicles operated in regions where de-icing agents are heavily used may experience premature corrosion at the rear subframe suspension mounting points. As the corrosion progresses, material thinning may occur and could result in fracture and failure of rear suspension components.

Describe the safety risk:
If the mounting points for the rear control arm or lower arm fail, the rear wheel(s) may become misaligned or inadequately retained, which could adversely affect vehicle handling, stability, and braking performance, increasing the risk of a crash or injury.

Describe the cause:
Rear subframes manufactured with improper coating specifications may result in insufficient paint adhesion and premature paint peeling near the arm bracket weld area. In regions where de-icing salt is heavily used, the exposed area may corrode prematurely. As the corrosion progresses, material thinning and driving vibrations could cause the mounting area to fracture and fail.

Identify any warning which can precede or occur:
Abnormal noise or vibration from the rear suspension and changes in vehicle handling may be experienced during vehicle operation.

Description of remedy program:
Registered owners of all affected vehicles will be contacted by mail and asked to take their vehicle to an authorized Honda or Acura dealer. The dealer will inspect the rear subframe, depending on the level of corrosion found, the dealer will either install a rear subframe reinforcement kit, repair or replace affected rear subframe components.

How remedy component differs from recalled component:
The remedy components have improved pre-paint treatment and increased coating thickness.

Identify how/when the recall condition was corrected in production:
The supplier improved the pre-paint treatment process in August 2022 to improve consistency in production quality. In January 2023, coating thickness was increased as part of a product improvement initiative intended to enhance long-term durability.

Describe the recall schedule for notifications:
Dealers have been notified. Owner notification will begin in July 2026.

Owners can determine if their specific vehicles are included in the recall by visiting www.Honda.ca/recalls , www.Acura.ca/recalls , or by calling 1-888-946-6329.

As of May 28, 2026, Honda Canada has had one reported claim for this issue.
