What is wrong

On certain vehicles, the weight sensor for the front passenger seat may not have been manufactured properly. As a result, the passenger-front airbag and knee airbag could deploy in a crash that doesn't require them to. Note: This recall is an expansion of Transport Canada recall no. 2024-059. If the weight sensor fails, the SRS warning light would turn on in the instrument panel.

Why it matters

An airbag system that doesn't work properly could increase the risk of injury in a crash.

What the dealer will do

17 April 2025

Transport Canada lists: MDX 2014–2020

What is wrong

On certain vehicles, the recall repairs completed by a Honda or Acura dealer during recall AL65/AL66 (Transport Canada recall no. 2019-159) may not have been effective. As a result, a second repair is required. On certain vehicles, water could enter the tail lamps on the tailgate and cause a short circuit. As a result, the fuse could blow and cause a complete loss of rear lighting. Note: This recall replaces recall AL65/AL66 (Transport Canada recall no. 2019-159). Vehicles that previously had a fuse harness installed under that recall do not require this repair.

Why it matters

A loss of rear lighting could make the vehicle less visible and increase the risk of a crash.

What the dealer will do

Acura will notify owners by mail and advise you to take your vehicle to a dealership to install a fuse harness. The dealer will also inspect and, if necessary, replace the tail lamps on the tailgate and repair the body dust sealer.

What is wrong

This recall is for low-pressure fuel pumps installed on certain vehicles or sold at dealerships as a replacement part. On certain vehicles, the low-pressure fuel pump could fail. If this happens, the engine may run rough or may not start and the check engine light may turn on. This could also result in a sudden loss of engine power while driving. Note: This recall replaces Transport Canada recall no. 2023-679. Vehicles that were repaired under that recall don't require this repair.

Why it matters

A sudden loss of engine power could increase the risk of a crash.

What the dealer will do

The company will notify owners by mail and advise you to take your vehicle to a dealership to replace the fuel pump motor.

What is wrong

On certain vehicles equipped with a V6 engine, the connecting rod bearings could wear prematurely and become damaged. If this happens, the engine could make abnormal noises and a warning light may turn on. If you continue to drive the vehicle with these symptoms, the engine could fail.

Why it matters

An engine failure could cause a sudden loss of power and/or increase the risk of a vehicle fire. Both issues could increase the risk of a crash or injury.

Transport Canada lists: MDX 2018–2019 · HR V 2018 · Odyssey 2018–2019

What is wrong

Certain vehicles may fail to conform to Canada Motor Vehicle Safety Standard (CMVSS) 135 - Light Vehicle Brake Systems. A problem with the rear brake system may cause gas bubbles to form in the brake fluid.

Transport Canada recall 2018167 · manufacturer campaign HN36 / AL44

6 April 2018

Transport Canada lists: MDX 2018 · Pilot 2018

What is wrong

Certain vehicles equipped with power driver and passenger seats may fail to conform to Canada Motor Vehicle Safety Standard (CMVSS) 207 - Anchorage of Seats and CMVSS 210 – Seat Belt Anchorages. The front driver and/or passenger seats may have been assembled with improperly manufactured rivets to secure the seat slide rails to the forward seat feet. In the event of a crash, the rivets may break and allow the front seat(s) to separate from the seat feet, which would fail to meet the requirements of the standard(s), and could increase the risk of injury to the seated occupant.

What the dealer will do

For Pilot models, dealers will replace the “H” frame (seat rail assembly), on both front seats, and for affected MDX models, dealers will replace the driver’s seat frame assembly.
