Service brakes, hydraulic:pedals and linkages
Model years: 2023, 2024, 2025
Problem: Honda (American Honda Motor Co.) is recalling certain 2021-2025 Acura TLX, 2023-2025 Acura MDX, and 2023-2025 Honda Pilot vehicles. The brake pedal pivot pin was not secured properly, which can cause the pedal to shift out of position. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard numbers 108, "Lamps, Reflective Devices, and Associated Equipment" and 135, "Light Vehicle Brake Systems."
Risk: A brake pedal that shifts out of position can prevent the driver from applying the brakes as intended, increasing the risk of a crash or injury.
Fix: Dealers will inspect and replace the brake pedal assembly as necessary, free of charge. Owner notification letters were mailed July 29, 2025. Owners may contact Honda's customer service at 1-888-234-2138. Honda's numbers for this recall are FLX and XLY.
Service brakes, hydraulic:foundation components:master cylinder
Model years: 2020
Problem: Honda (American Honda Motor Co.) is recalling certain 2020-2021 Civic, 2020-2023 Ridgeline, 2021-2023 Passport, 2021-2022 Pilot, and 2020 Acura MDX vehicles. The tie rod fastener that connects the brake booster and the brake master cylinder may have been improperly assembled during manufacturing, which can cause the brake master cylinder to separate from the booster assembly.
Risk: Brake master cylinder separation can cause a loss of brake function and increase the risk of a crash.
Fix: Dealers will inspect and repair the brake booster assembly as necessary, free of charge. Owner notification letters were mailed August 7, 2023. Owners may contact Honda customer service at 1-888-234-2138. Honda's numbers for this recall are VEU, AEV, and ZET.
Service brakes, hydraulic:foundation components:disc:caliper
Model years: 2017, 2018, 2019
Problem: Honda (American Honda Motor Co.) is recalling certain 2017-2019 Acura MDX, 2017-2018 Acura MDX Sport Hybrid, 2018-2019 Honda HR-V and Honda Odyssey, and 2016 Honda HR-V vehicles. The rear brake caliper pistons may have an insufficient coating, causing gas pockets to form, reducing brake performance. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 135, "Light Vehicle Brake Systems."
Risk: A reduction of braking performance increases the risk of a crash.
Fix: Owners will be notified, and Honda or Acura dealers will bleed the brakes, free of charge. The recall began December 11, 2018. Owners may contact Honda customer service at 1-888-234-2138. Honda's numbers for this recall are C31 and L30.
Traction control system; service brakes, hydraulic:antilock/traction control/electronic limited slip:control unit/module
Model years: 2005, 2006
Problem: Honda is recalling certain model year 2005 Pilot vehicles manufactured July 29, 2004, through August 29, 2005; model year 2005-2006 Acura MDX vehicles manufactured September 16, 2004, through September 22, 2005; and model year 2005 Acura RL vehicles manufactured March 1, 2004, through June 29, 2005. An electrical capacitor may have been damaged during the manufacturing of the Vehicle Stability Assist (VSA) control module causing intermittent, automatic, minor brake application. However, if the driver applies the brakes while the VSA is malfunctioning, the vehicle may come to an abrupt stop. Additionally, due to a loose ground connection, certain model year 2005 Pilots have a VSA system that may apply partial brake force, without the illumination of the brake lights, whether or not the driver is using the brakes.
Risk: Sudden inadvertent braking, especially without illumination of the brake lights, may increase the risk of a vehicle crash.
Fix: Owners will be notified and instructed to take their vehicles to a dealer of their respective brand. The dealer will install a partial wiring harness containing a capacitor for the VSA modulator, free of charge. The affected model year 2005 Pilots will have their ground connection tightened. The recall began on April 22, 2013.
