What's wrong?
The front seat heater in the 2010 Mazda CX-9 uses an electrical control circuit to manage heat in the heated front seats. When the seat heater is switched on, that circuit sends power through the heater element so the seat warms while the rest of the seat assembly stays within its designed electrical limits.
In affected CX-9 vehicles, the problem is in the seat heater control circuit, not the seat cushion itself. Under extremely cold conditions, insufficient electrical grounding lets the circuit overheat and fail. Grounding gives electricity a controlled return path; without enough grounding, heat builds in the control circuit instead of the system operating normally.
There is no warning sign before failure. The heater control circuit can overheat under the listed cold conditions, and the heated seat can stop working when the circuit fails.

What's the safety risk?
Seat heater electrical damage can burn the seat cushion surface or create smoke or fire risk. If you smell smoke, see heat damage, or notice unusual heat, stop using the seat heater and schedule service. Repair will be free at any franchised Mazda dealer once available.
What should I do?
- Check your VIN to confirm your 2010 Mazda CX-9 is included in this recall.
- Contact a franchised Mazda dealer if your VIN is included and ask whether the front-seat heater recall repair is open for your vehicle.
- Schedule the added ground-harness repair that protects the front-seat heater control circuit from overheating.
- Bring the recall notice if Mazda mailed one. If not, reference recall number 10V051 when you call.
- Avoid using the front seat heaters until the dealer completes the free repair.
What happens at the repair
At the dealer, a Mazda technician installs an additional ground harness on the heated front seat control system. If inspection shows damage or failure in the seat heater control circuit, the technician replaces that circuit, repairs the seat, or both. The filing states the safety recall began on March 9, 2010. The dealer repair is free once available, including the grounding work and any needed seat heater control repair.
