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

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.

FIRST THE PASSENGER AIRBAG JUST STOP WORKING, THE AIRBAG LIGHT ON THE DASH WILL NOT GO OUT AND THE DISPLAY LIGHT BY THE GEAR SHIFT SAYS #2 AIRBAG NOT WORKING. SECONDLY WHILE DRIVING THE CAR I GET A SCREACHING SOUND FROM 1ST TO 2ND GEAR COMING FROM THE ENGINE. THOUGHT IT WAS MAYBE THE SENSOR ON THE BRAKES BUT NOT SURE. JUST HAD WORK DOWN ON THE CAR ABOUT 3 WEEKS AGO, THE CAR WOULD NOT COME OUT OF 1ST GEAR. ECM WAS REPLACE AT DEALERSHIP

The evening of April 17th, 2022, I started experiencing an issue with my vehicle. My car started making a fluttering noise it sounded like someone was shuffling a deck of cards and the RPMs would get to 3 during acceleration then drop and I’d lose power. There were no warning lights present, no notification or indicators on my dash, no odors, and no smoke emitting from my car. I parked my car at home not knowing what the issue was or where the noise was coming from. The next morning, I called to schedule an appointment and I booked with Infiniti in Timonium. After scheduling my appointment, I went out to check my car and when I started it the noise was still there. It ran for a few seconds then my check engine light cut on. Looking to get a pre-diagnosis to have additional info about the condition of my car I take it to Autozone on liberty road to have codes pulled. The codes that came back were P0014 and P0024 both camshaft codes. However, there were still no other symptoms of odor or smoke just the fluttering noise and now my check engine light. On the way back home my car stalls at Liberty Road and Rolling Road and won’t cut back on. I contacted AAA and had it towed to Infiniti the same day. I was assigned to [XXX] as my service advisor. The car was at Infiniti in Timonium for close to a month when [XXX] reached out to notify me of the presence of sludge and metal shavings in my oil pan and my engine being seized. He was adamant that it came from a lack of maintenance. I was using my third-party warranty and they requested that I send proof of maintenance. I submitted my maintenance invoices to Sean, and he forwarded them to my Warranty Company. I provided invoices for my last 3 oil changes. I wasn’t due for a fourth for another 6-700 miles. I bought my car at 35,796 miles and I’m currently at 70,042 (42 miles out of the power train warranty). I followed manufactures 10k guideline. The vehicle is available for inspection upon request.

Initial fault was no cabin heat. Service department determined coolant was low. Coolant system passed pressure test. Coolant was found to be leaking into cylinders past head gaskets. After head gasket replacement, engine broke down on highway and car was towed to dealership. Catastrophic overheat damage in lower end. Engine long block was replaced to correct. Multiple identical/similar occurrences reported on infinitiq60.org. Failure is normally failed head gasket or porous engine block. 2017 models especially affected. Infiniti consumer affairs completely unresponsive if vehicle is outside powertrain warranty. Safety at risk due to potential engine failure and vehicle stoppage at any time. No indications received at any time indicating failure. Temp gauge never indicated spike or failure. Only indication was lack of cabin heat, but coolant was basically empty. The problem was reproduced by dealer after servicing coolant and seeing subsequent engine internal consumption of coolant. Vehicle was inspected by Infiniti service department and MPP third-party warranty company. All vehicle service records since purchase are available.
