What's wrong?
The driver and front passenger seat belts in the 2014-2015 Acura Mdx and 2014 Acura Rlx are designed to pull out smoothly, latch across the occupant, and retract back into place. The belt has to move freely so the person in that seat can buckle in with the belt positioned correctly.
On affected vehicles, the seat belt does not extend or retract as designed in low temperatures. That means the belt can bind, stop short, or fail to return properly when the cabin or belt mechanism is cold. If the belt will not extend far enough to latch, the person in that seat is not properly secured.
There is no warning sign before failure. In cold weather, the first thing an owner notices is the belt refusing to pull out or retract normally when someone tries to buckle in.
Who's affected?
Spans the Mdx and Rlx across the 2014 and 2015 model years, with the seat belt as the listed component.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific vehicle is included in this recall.
What's the safety risk?
A driver or front passenger seat belt that does not function cannot provide its intended restraint in a crash, which increases injury risk. Until the belts are replaced, confirm your VIN and schedule service promptly if this recall applies. Repair will be free at any franchised Acura dealer once available.
What should I do?
- Check your VIN to confirm your 2014-2015 Acura Mdx or Rlx is included in this recall.
- Contact a franchised Acura dealer and ask whether the free driver and front passenger seat belt replacement is open for your VIN.
- Reference recall number 14V639 when you call, and mention the seat belts do not extend or retract properly in low temperatures.
- Bring the recall notice if Acura sent one. If you never received a notice, ask the dealer to confirm the recall by VIN.
- Avoid using the vehicle with a driver or front passenger seat belt that will not extend, retract, or latch correctly.
What happens at the repair
At the dealer, an Acura technician replaces the driver seat belt and the front passenger seat belt covered by recall 14V639. The replacement parts and labor are free under the recall. The repair addresses seat belts that fail to extend or retract in low temperatures, so the technician replaces the affected belt assemblies rather than asking the owner to adjust or lubricate them. Acura owner notification began in November 2014, and the dealer handles the recall work through the Acura service desk.
