2017 Infiniti Q60

Subject: Safety Complaint: 2017 Infiniti Q60 - Recurring P052E Fault (Engine Shared with Mercedes) Vehicle Information: Make: Infiniti Model: Q60 Year: 2017 Engine: (Insert Engine Size, 2.0L) Incident Details: Code: P052E (Crankcase Ventilation Valve Performance) Symptoms: Check engine light, strong burnt oil smell, rough idling, low engine output/lack of acceleration. Problem Description: "I am filing this complaint to report a recurring, serious defect in my 2017 Infiniti Q60 regarding the PCV (Positive Crankcase Ventilation) system, throwing OBD-II code P052E. The vehicle experiences severe loss of power while driving, rough idle, and a strong odor of burning oil inside the cabin, which poses a fire risk and inhibits safe operation. It is well-documented that this vehicle utilizes an engine manufactured/designed in collaboration with Mercedes-Benz, and a recall exists within the Mercedes community for this exact code (P052E). However, Infiniti has not issued a corresponding recall, leaving owners of this shared-engine vehicle to pay for repairs on a known manufacturing defect. Given the severe symptoms and the recognized safety hazard of this defect by other manufacturers, I request an investigation into this safety issue

The contact owns a 2017 Infiniti Q60. The contact stated while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended, with the check engine warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed with turbo charger failure. The contact was informed that the turbo charger needed to be replaced. The vehicle was not repaired. The contact referenced an unknown recall with a similar failure description; however, the VIN was not associated with the recall. The manufacturer was made aware of the failure but provided no assistance. The contact was informed that there were no recalls associated with the VIN. The failure mileage was approximately 130,000.

Engine threw a main bearing around 80 thousand miles in 2023, car was not modified other than different muffler on the back and aftermarket wheels and tires which has nothing to do with the engine. Car had oil changes every 3500-4500 miles with MOTUL full synthetic oil. No engines lights were given, car was taken to a Nissan dealership as manufacturer warranty was expired, my extended warranty was fidelity and they declined due to these aftermarket “changes” dealership gave me a quote over 25k dollars which is what I paid for the car in 2019. I understand it’s a luxury brand but these engines are well known for these issues and nothing is done other than some warranty extension for failing turbos which are also terrible and I believe to be the CAUSE of this thrown bearing, I have owned so many Nissans and will most likely never own another after this mistake. Still love the car but the people that buy these deserve better for the cost. The car is currently sitting in a garage because the cost is absurd.

Car malfunction light comes on spontaneously and runs rough and losses power and rpm can go to 4 at 35 mph and usually happens when car is idling parked for a little while. Them I cut it off and let it sit it goes back to normal. I also had prior problems with it smoking from tailpipe and it’s documented at dealership in Columbia SC and they said it wasn’t smoking enough to replace the turbos at the time but I got a notification from manufacturer about turbo malfunction.

Infiniti called me on 05/08/24 to discuss and review Infiniti Case # [XXX] including Infiniti’s subsequent refusal to remedy a defective SRS (Supplemental Restraint System) sensor on my 2017 Infiniti Q60 with 54,100 miles (VIN: [XXX] ). This defect was confirmed on 05/07/24 by Infiniti of Melbourne Florida through an authorized technician. While I am the original owner of the vehicle, Infiniti stated they will not provide any financial assistance to rectify the issue because the vehicle is outside of the manufacturers warranty, while acknowledging that there have been numerous customer complaints related to this problem and that Infiniti has been aware of defective SRS parts effecting a critical safety device that renders the air bag system inoperable. Moreover, to repair such a deficiency, based on Infiniti’s design, the entire seat must be replaced costing over $8K, an exorbitant and onerous amount, often more than 50% of the vehicles value. This excessive financial charge has deliberately burdened Infiniti owners with a safety related component. For several years this issue has been recurrently discussed on multiple public forums and yet Infiniti has intentionally decided not to remedy this safety issue or provide any assistance or consideration to its customers. I’ve attached an Infiniti forum link (one of dozens) proving that Infiniti has known about this problem going back over a decade and failed to take any action and instead prolonged a predatory pricing scheme that is harming owners. [XXX] ) As a result of Infiniti’s complete intransigence on a safety related matter, the National Hwy. Traffic Safety Admin. (NHTSA), should compel Infiniti to remedy this situation. It’s hoped that Infiniti will take immediate action to correct this situation and not abandon its owners in an untenable, unsafe and unjustifiable predicament. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

OCS passenger seat weight sensor failed. Dealership verified this. They say to repair will be $8000 to replace whole seat. This is a common problem with hundreds of complaints mentioned on online forums. There was a recall for this issue on prior year Infiniti models but that recall doesn’t include newer than 2016. Infiniti refuses to replace under warranty. (They replaced the driver seatbelt retractor assembly under warranty, but won’t repair the airbag issue). The weight sensor does not register that someone is sitting in the seat.
