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

While driving on a highway (i95, speed 55 MPH) the engine suddenly died, was able to pull over and restart the engine, which now made a terrible mechanic noise. Could drive off to a smaller road where the engine stalled again. Had to tow the car to the dealer, who advised that the engine needed to be changed. Two weeks later the engine was finally changed but now this time they stated that the turbos needed to be changed. The parts were, however, on back order - dealer cannot say how long before it can be repaired. After 3 weeks and many phone conversations I still do not have a car. This is after all a new (18000 miles) >50k car but apparently it was nothing but a lemon.

I purchased my 2017 infiniti q50 as a certified dealer owned vehicle with 4710 miles on it from airport infiniti on 12/31/2018. Since taking possession of the car, I have had three separate instances where my car lost power during acceleration, in which one of the instances nearly caused me to be hit by a semi-truck when crossing a divided highway. I have provided videos to the manufacture but they have refused to take action because the vehicle does not set any dtc codes. When this condition happens my 3.0t q50 accelerates extremely slow even with 100% throttle. The net result is that when I intend to cross a divided highway, I experience a 1-1.5 second delay from the time I push down the accelerator to when the car begins to move, then the acceleration from 0-15mph can take upwards of 5-6 seconds. The resulting feeling is a car that rolls into a dangerous intersection and exhibits stall like conditions. Only once did the car set dtc codes during this instance. The codes set were b130d, c1a16 and po340. These codes set the first instance, but have not set during the past two occurrences of the same acceleration issue. These instances are completely random which make them extremely dangerous. For instance, the car will be driving completely normal, I will stop and an intersection and then when I go to turn out into the intersection, I go into this stall condition without warning. The dealership has had the car 4 separate times and each time they have refused to fix anything on the car, despite having a video of the occurrence and confirming that the acceleration was entirely abnormal. I have no choice but to drive this car if infiniti refuses to fix it, but feel it is likely that it will cause injury or death to me and my family if I drive it. I have attached a summary of the daily log I have been keeping since I purchases the car on 12/31/2018.
