2016 Infiniti Q50

The vehicle experienced a failure while driving, producing heavy smoke and requiring the car to be stopped immediately. The “Low Oil Pressure – Stop Vehicle” warning light illuminated on 2/19/2026. The vehicle was subsequently taken to an Infiniti dealership for inspection. Upon evaluation, the dealer determined that both turbochargers have failed and are leaking oil. The turbochargers are covered under an existing warranty extension; however, the engine has failed also. The vehicle experienced a catastrophic engine failure at approximately 50,230 miles, after which both the engine and turbochargers were replaced under warranty with the cause listed as undetermined. Both the original and replacement engines have now failed in the same manner, with turbochargers leaking oil and producing visible smoke, indicating a likely recurring defect or unresolved underlying issue. The replacement engine failed after only 40,000 miles, further raising reliability concerns. Infiniti quality actions (P4A05 and P4A06) identify turbocharger oil leakage as a known issue, aligning with the current failure. The dealership has confirmed the turbochargers are leaking oil but will only replace them if a full engine replacement is authorized by me at a cost of $15,556.49.

* the passenger airbag light came on July 2025. I was not in a accident the light just came on. * 7/29/2025 I took my car in for service at Infinity of Las Vegas (the only Infinity dealership in Las Vegas) I asked to check why the airbag light was on. I was told the occupant sensor unit was abnormal. Sensor and module internally shorted out. Recommend to replace passenger front seat frame assembly (only available as a 1 piece both sensor and module internally shorted seat frame Assy). @ $ 8678.76. Because it’s a different seat from the original seat, I would have to also replace the seat belt. @ 116.87. * It is not recommended to drive a car with the air bag light on. This car is my only source of transportation. * on August 4, 2025 I took my car to Auto Dynamic Services and they suggested initial repair was to replace the Occupant Detection Module. The part was ordered from Nissan, when they received the part it was an updated part design which was slightly larger with more pins than the original part and could not be used on my car. They reordered the part from another Nissan retailer ensuring it matched the original part for my car. Now it’s Aug. 27th, 2025. Auto Dynamic received the correct replacement module. Unfortunately the part was replaced and the airbag light came on again. They also stated the seat would have to be replaced in order for the airbag light to go off. For around the same price. It cost me 1800.00 to find this out. * I do not have money to resolve this issue especially if the driver airbag errors next, I am fearful of the unknown driving around with the airbag light on. If in an accident possibly not being covered because I was driving with a know issue. Or the bags just deploying randomly. * On [XXX] I traded a perfect running car in, I did not receive much on the trade as the airbag light is on. I can drive safely and register the car when required * it looks like there was a recall but the Q50 2.0 turbo was not included.

I’m reporting a safety issue with my 2016 Infiniti Q50. Last Friday [XXX], my the car wouldn’t crank and there was minimal dashboard power, but the engine wouldn’t start. After receiving a jump, I had the battery replaced assuming it was the issue. However, six days later, while driving, the vehicle suddenly lost all electrical power mid-drive with no warning or dashboard alerts. The engine shut off, the brake pedal became stiff, and I was unable to use any power-operated functions, such as rolling down the windows (98 degree day in Texas) or opening the trunk, which contained my emergency tools. A police officer had to assist and the vehicle was towed. Upon inspection, the issue was traced to corroded battery terminal cables, which were blocking the signal from the new battery and causing the full shutdown. This is a serious safety concern as complete power failure while driving, with no warning, and no manual trunk release for emergencies, could place drivers at significant risk. I’m submitting this for review and potential recall consideration. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Passenger seat light remain on for 4 months the went away. Then the airbag light came on. Took it to Infiniti of Tampa where they supposedly done diagnostics. They cause additional lights to appear on my dashboard to include the steering hard to turn. When I purchased the vehicle in October 2016 I was unaware of any recalls. I found out about a month ago there approximately four recalls for 2016 Infiniti Q50.

The hood of my vehicle is raised on the upper right side. It was a small opening but now it has gotten bigger. I'm afraid that the entire hood may come off at a high speed. I also have rust spots on the top of my car close to the sunroof. I use Infiniti of the Palm Beaches for all of my services and have reported both concerns and was told it was normal wear and tear. I have owned many cars and never had the problems that I've had with a vehicle.

The car has only 50,000 miles and the valve body of the car just burnt out. I’ve done all the mandatory/ recommended maintenance and with the history of the brand I expected better quality of their product. Would greatly appreciate the accountability on this issue and some effort to fix this for the population.

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.

Then engine light came on. And the vehicle decline in power. It moves very slow.

On 12/11/21 my vehicle had limited turning (left or right) capability. The vehicle has < than 23K miles, was purchased at Bommarito Infiniti, and has been serviced at the same dealership since I purchased it. I bought the vehicle new and drove it over the last 5 years as a back-up vehicle to a Chevy Cruze (w/greater than 180K miles on it and no faulty parts). I did not purchase the extended warranty because it was supposedly a reliable vehicle, based on my prior history/ownership of a 2006 G50. I made timely payments for 5 years, performed all of the required maintenance, and took my car in for all of the Infiniti “recalls.” After the ability to turn failed, I took the vehicle to Bommarito Infiniti for a diagnostic and routine oil change. The steering diagnostic found 3 leaks on the steering rack and pinion., (no oil was visible on the ground). I did not have any warning lights for low steering fluid or service required indicators, but the dealership stated the power steering fluid was low. I contacted Infiniti Consumer Affairs department for review of the faulty part, considering that I had less than 23k miles on the vehicle. Stewart at Infiniti Consumer Affairs stated that the claim for repair assistance was denied due to the vehicle being out of warranty and the "lack of service history" with Bommarito Infiniti. When I questioned him about defining/explaining what he meant by the lack of history, he could not explain his statement. He placed me on hold, and then returned only to reiterate his previous statement. I then informed him and verified with the dealership that I did not deny any required repair or service that was recommended/required. The dealership also stated that the rack and pinion that was installed on my Q50 had to be a faulty part because this is the 1st time that a 2016 Q50 with less than 36k miles has ever needed this part replaced. This is a safety issue and a crash waiting to happen!
