Turbos blow prematurely, and the motor can end up with porus block at any mileage
2017 Infiniti Q50 engine complaints
Page 2 of 2: complaints 11 to 17 of 17, newest first, as owners wrote them.
The car needed new sprockets after 105K miles. I haven't seen anyone else have this problem, so my car maybe a lemon. But just in case more people start reporting it, I just want to make sure it's on record. The dealership has no idea why they'd fail, as I have had regular, full synthetic oil changes. It's a hefty repair.
Engine failure due to porous motor and oil deprevation related to a tsb
The contact owns a 2017 Infiniti Q50. The contact stated that while his son was driving at approximately 45 mph, the vehicle shut off without warning. Due to the failure, his son lost complete control of the vehicle and drove into a ditch. The air bags did not deploy. The contact's son was not injured as a result of the accident and did not seek medical treatment. The police were not called to the scene and a report was not filed. Due to the failure, the vehicle was towed from the scene to an independent auto repair shop. The contact was informed by the auto repair shop the serpentine belt had shredded inside the engine which caused the failure. They also informed him that there was a service bulletin on the vehicle in relation to the failure. The contact's son reached out to the manufacturer where they both agreed to an unknown settlement. The vehicle had been repaired. The failure mileage was 28,097.
Camshaft pos sensor went out during driving. Car lost power and jerked. Had car looked at by independent service station and heard knocking. Brought car to dealership and was determined to have a blown engine. Was specifically told that the turbos were 'eating' the oil and not allowing oil to flow to lower end of motor. Which caused failure to main bearing in cylinder 3. Car needs a new engine. Service department has seen this before with same year make and model of vehicle
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 have a infiniti q50s redsport 2017 actually have 34000 miles in the odometer. This car have a factory defect that involves engine parts in this case serpentine belt, belt tensioner and pulleys. There is a tsb at this time for this issue but in the majority of cases the cars still showing up the issue. Major issue at this time is that serpentine belt brokes while car is on move. The car needs to be stoppend since engine overheat and also baterry light goes on. The belt tensioner get stuck and pulleys in some of the cases melt down. In my case my car has visited 2 times with the same issue. There is a tsb that pretend to fix that issue realigning the AC compressor. At this time there is few houndreds maybee more cara affected. I think this is a major issue since the serpentine belt broke and engine stop being functional due overheating. This can cause a major accident or other security problem.
