INFINITI is recalling 6,562 2013-2015 Q50 Hybrid, M35 Hybrid, and Q70 Hybrid vehicles because a software error can make the throttle chamber reopen after a throttle position sensor signal returns. The vehicle can gradually accelerate unexpectedly, increasing crash risk; the dealer repair will be free once available.

What's wrong?
The throttle position sensors on the 2013-2015 INFINITI Q50 Hybrid, M35 Hybrid, and Q70 Hybrid tell the engine control module where the throttle is. The engine control module is the computer that manages engine response. It uses those sensor signals to control the throttle chamber, which opens and closes to regulate air going into the engine.
On affected vehicles, a software error changes how the system reacts when the signal from one of the 2 throttle position sensors is lost. The engine control module enters fail-safe mode and partly closes the throttle chamber. If the missing signal returns, the throttle chamber opens without following the throttle position sensor signal.
There is no warning sign before failure. The filing does not identify a dashboard light, sound, pedal feel, or other early symptom an owner can count on before the software fault occurs.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific sedan.
What's the safety risk?
If the throttle chamber reopens, the vehicle can gradually accelerate without the driver asking for more power. Unexpected acceleration increases crash risk, especially in traffic. If your INFINITI surges, move out of traffic, brake steadily, and contact the dealer. Repair will be free at any franchised INFINITI dealer once available.
What should I do?
- Check your VIN to confirm your 2013-2015 INFINITI Q50 Hybrid, M35 Hybrid, or Q70 Hybrid is included in this recall.
- Contact a franchised INFINITI dealer to ask whether the free ECM reprogramming is open for your VIN.
- Schedule the ECM reprogramming that corrects the throttle-position-sensor software error tied to unexpected acceleration.
- Bring the owner notice if you have it, or reference recall number 14V583 when you call.
- Drive with extra space until the repair is complete, and tell the dealer if the vehicle has accelerated unexpectedly.
What happens at the repair
The listed repair is an ECM software reprogramming. Once the dealer repair is available, an INFINITI technician updates the engine control module so it responds correctly if one throttle position sensor signal is lost and then restored. Parts and labor are covered under the recall. If your VIN is included, ask the INFINITI service desk to confirm the recall appointment and explain any driving guidance before you bring the vehicle in.

Frequently asked questions
What is recall 14V583?
Recall 14V583 covers 6,562 2013-2015 INFINITI hybrid vehicles with engine control module software that can reopen the throttle chamber after a throttle position sensor signal returns. The vehicle can gradually accelerate unexpectedly, increasing crash risk. INFINITI dealers reprogram the ECM for free.
What should I do if my 2013-2015 INFINITI Q50 Hybrid, M35 Hybrid, or Q70 Hybrid is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 14V583. If it is, contact a franchised INFINITI dealer to schedule the ECM reprogramming. Reference recall number 14V583 when you call. The repair is free.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to repair safety defects at no cost, and INFINITI dealers reprogram the engine control module free of charge. The recall began on November 10, 2014, so the dealer repair path is open.
What is the safety risk from recall 14V583?
The safety risk is unexpected acceleration. If the signal from a throttle position sensor is lost and then restored, the throttle chamber can reopen regardless of the sensor position signal. That can make the vehicle gradually accelerate and increase crash risk.
What if I bought my INFINITI hybrid used?
The free recall repair still applies. Federal recall law follows the vehicle, not the first owner. Check your VIN to confirm whether your specific Q50 Hybrid, M35 Hybrid, or Q70 Hybrid is included, then give recall number 14V583 to the INFINITI dealer service desk.
