What's wrong?
The hybrid propulsion system in the 2014 INFINITI Q70 Hybrid and Q50 Hybrid uses an electric motor as part of the drivetrain. When the vehicle is moving on electric power alone, that motor supplies the force that keeps the vehicle moving without help from the gasoline engine. Software coordinates that handoff between electric drive and the rest of the hybrid system.
In this recall, a software error affects that control logic. While the vehicle is being driven using only the electric motor, the motor can stop working. That means propulsion from the electric side of the system stops instead of continuing as commanded.
There is no warning sign before failure. If the problem happens, the change is the loss of electric motor drive while the vehicle is already in motion.

A matching 2014 INFINITI Q70 Hybrid or Q50 Hybrid does not guarantee inclusion. Check your VIN to confirm whether your specific sedan is included.
What's the safety risk?
If the electric motor stops working, the vehicle can act as if it has stalled and crash risk increases. Until the repair is done, schedule service soon and drive cautiously, especially if the vehicle loses power unexpectedly. Repair will be free at any franchised INFINITI dealer once available.
What should I do?
- Check your VIN to confirm your 2014 INFINITI Q70 Hybrid or Q50 Hybrid is included in this recall.
- Contact your nearest franchised INFINITI dealer and ask whether recall number 14V581 is open for your VIN.
- Schedule the free motor-inverter software reprogramming that fixes the electric-motor shutdown condition.
- Bring the recall notice if INFINITI mailed one. If not, reference recall number 14V581 when you call.
- Drive cautiously until the repair is complete and pull over safely if the vehicle loses electric-motor power.
What happens at the repair
At the dealer, an INFINITI technician connects the vehicle to service equipment and reprograms the motor inverter software so the hybrid drive system uses the corrected control logic. INFINITI lists this repair as free of charge. The filing does not list a current remedy status, so confirm availability with the INFINITI service desk before arranging the visit. Once available, the dealer repair is free.
