ENGINE

My 2016 Q50 was driving strangely, but no indicator light came on the dashboard. I took the vehicle to the dealer where I purchased it and was told that the engine is dying. No other information was given to me. I called the service advisor asking what in particular was wrong with my car, but he said he wasn't sure. I took issue with the fact that my engine died, and no warning lights what-so-ever showed on the dash. I would only take my car to the dealer for repairs, maintenance and oil changes. I also learned that cars should not go beyond 3,000 miles for an oil change, but for some reason Infiniti oil changes were 10,000 miles in between. I believe this could be a reason the engine died...there was never an oil change indicator light illuminated as well. I feel that Infiniti is responsible for an engine dying on a vehicle with less than 100,000 miles on it.

ELECTRICAL SYSTEM,SERVICE BRAKES,ENGINE

Something happened to cause power loss. I checked the recalls and work that was supposed to be performed but didn’t get done like it was supposed to. I need to have it checked now asap! I see 2 engine replacements and also the turbos and 2 of the catalytic converters. The last 2 need replacing as well or it’s not going to be right.

TIRES

Had 2 new tires installed on the rear of the car and they both busted at the seam. Shredded the tires and damaged 4 wheels.

VEHICLE SPEED CONTROL

OUTPUT SPEED SENSOR on 2016 INFINITI Q50t - Took vehicle in for oil and filter change 2 days ago. I drove the car about 40 miles, without incident. Went back to same place for state inspection yesterday. I drove about 2 miles from the inspection place and park in shopping lot. Went in business to shop for about 30 minutes. Returned to vehicle and drove about 100 yards through the parking lot. The car appeared to lose power and made a jerking movement as if it didn't want to go. I drove out onto a very busy street and we were almost rear ended by other traffic. I pulled up in another parking lot to assess the problem. I could not determine what was causing the car not to pick up speed. I drove to an AutoZone: battery checked out at 90 percent good; no electrical problems noted either. I drove off about 1 block from AutoZone: the CEL came on for the first time. I went back to the AutoZone to get them to check it out. The diagnosis code is P0720: vehicle speed sensor. I went back to the inspection shop the next day and I was told the same code. I took the vehicle to the dealership and I was told that I need to replace the whole transmission. I purchased the vehicle about 8-1/2 years ago; garage kept; only put 60k miles on car since purchase. Car has approx. 108k miles now. This is not only a problem with 2014 -2015. When I purchased the car in 2018, I feel like the dealership should have informed me that this was a problem with Q50s. This is not just an issue with previous years; this is a problem with 2016 as well. This vehicle is very clean/outstanding: no accidents, no body damage, immaculate leather seats, no repairs in 8-1/2 years and all of a sudden this fault code comes up with no previous indication that the transmission was not working properly. There needs to be a RECALL for this vehicle due to this common issue.

ENGINE

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.

ELECTRICAL SYSTEM

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)

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

ELECTRICAL SYSTEM,ENGINE

The engine check light came. I also received a letter from infinti for recall. The power of the vehicle declined.

ENGINE

Engine manufactured with porous block causing coolant to mix with oil resulting in bearing failure. Vehicle has less than 60k miles and I have seen numerous reports on Infiniti Q50/Q60 forums with people having the exact same issue. Some vehicles have had multiple engine replacements. Vehicle out of warranty due to age. Have not been able to drive vehicle for over a year and was told I should report issue to the government since Infiniti has not stepped up and done a voluntary recall.
