In August 2026, while driving, the vehicle suddenly lost acceleration and engine power and would only travel at a very slow speed. The check engine light came on. The driver had to safely stop, turn the engine off, and restart it. After restarting, the vehicle temporarily regained acceleration and normal speed. This problem has occurred more than once and creates a serious safety risk in traffic, especially when merging or crossing intersections. An INFINITI dealer inspected the vehicle and advised that the problem may involve the turbocharger system, with repairs estimated at approximately $4,000. INFINITI Consumer Affairs was contacted about the loss of acceleration but declined financial assistance because of the vehicle's mileage/warranty status. The vehicle was previously an Enterprise rental vehicle and had prior INFINITI service history. The vehicle is available for inspection. I am requesting investigation of this sudden loss-of-power condition.I am aware that the federal safety agency Recall 21V‑234 / INFINITI Campaign R20C5 involved certain 2021 Q50 vehicles and an ECM software condition associated with a warning light, reduced power, and possible engine stall while driving. My VIN currently shows 0 unrepaired recalls, but I am requesting verification of whether this campaign ever applied to my vehicle and, if so, when and at what mileage the ECM reprogramming was completed. My vehicle is now experiencing a Check Engine Light and sudden loss of acceleration/power while driving, which temporarily improves after the engine is shut off and restarted. I am also aware of INFINITI TSB ITB22-038D/EM22-007D concerning turbocharger replacement procedures for 2016–2024 Q50 vehicles equipped with the VR30DDTT engine. I request investigation of whether my present loss-of-power condition is related to the ECM, turbocharger/boost system, or another safety-related defect.

What owners say
The problem is on the recall, I understand my car is not on the VIN recall list but it's the same problem. Potential Recalls for 2017 Q50: Fuel Pump Control Module (2.0L engines): Improper software may cause the engine to stall.
My vehicle has been stalling and burning/leaking oil internally for some time now with white smoke coming from the rear. Well Infiniti sent a post card and stated that the emission warranty is extended for 120,000 miles which my vehicle has had the issue for some time and it was already over 120k miles at the time of the loss. The issue Infiniti reported in their postcard is, you may experience issue with the turbocharger, Overtime there is a possibility for the turbocharger thrust bearing to wear and leak oil internally. The most likely conditions you will experience are excessive white smoke from the exhaust, MIL-On an in rare cases reduced engine power or damage to the internal components. My vehicle is experiencing all these issues reported and the company, Infiniti, knows this is an issue and did not issue a recall the extended warranty instead, most people will not qualify for which will require people to thousand of dollars replacing the turbocharger assembly and engine control model. I got a quote and was told 8000 dollars unfortunately I cannot have repairs done. I believe it was January 2025 when the post card came from Infiniti identifying the issue
Car has white smoke coming from the exhaust and the oil level keeps decreasing. Car stalls and takes time to accelerate P0106 code pops up from engine.

My vehicle has been having issues for several months now. I have taken it to Nissan, an auto shop, and Infiniti and no one has been able to find out what’s wrong with it, why it stalls to start on a cold start. Infiniti has had my car for a month now because they believe it’s the fuel pressure sensor and they are waiting on the part, for which they have no estimated time of arrival, but they are not sure is that is what is wrong with the car.

My coolant reservoir kept on going empty, I took to dealer for service they replaced the radiator fan module and told me my engine was not porous. I was driving and my engine ended up stalling, turned off while I was driving in the freeway at a high speed cause me to almost lose control of my vehicle because everything stopped working. It looks like an inner rod failed possibly because of the coolant going into engine.
