2017 Nissan Pathfinder: check engine light

Filed Aug 13, 2026 · Engine · VA

SLUDGE IN ENGINE- UNDER 100,000 MILES We had been keeping up with all recommended services, and it is cosmetically perfect, but the car is now a total loss. A Check Engine light came on, and we began to notice a tremor/shake and took it to Southern Team Nissan. The Nissan dealer diagnosed sludge in the engine and said it would need a total engine replacement. The Nissan dealer advised that the cost of that would be more than the car was worth. After they pulled the pan to check if there was definitely sludge, the car then shook so badly that it felt unsafe to drive. Research shows that this is a known issue, with many cases of documented VQ35DD sludge problems. We see many listed cases on this website under complaints for 2017 Nissan Pathfinders.

October 2019, I noticed a loud clanking noise on our 2017 nissan pathfinder. I do not live near dealership, so we called and described symptoms. The servicer reported that while he couldn't diagnose without seeing the vehicle, guessed our radiator fan needed replaced due to being a common problem, not under warranty at approximately 65k ($1800 est.) cooling fan replaced by local mechanic for approximately $600 with an aftermarket part. This fan is imperative in keeping the temperature regulated and can cause further damage and safety concerns. Which leads me to my next complaint. Summer 2020. I take my pathfinder to my mechanic (brakes, tires, oil change). Upon pick-up, he informs of gritty oil that he has never noted in previous oil changes and recommends I change it again, before my routine 3-5k. I take it back a month later, august 2020 for inspection, oiled changed again. Within the next few weeks my check engine light turns on. The code is reading a fuel pressure temp sensor. Mechanic is unable to locate part, even from dealership. I begin having issues with engine surging while driving/idling, rattling engine, stalling at lights, issues starting including hesitancy followed by revving. Over two weeks, I was experiencing intermittent flashing indicator lights. No mechanic, auto parts was able to find a code. I called my closest dealership the last week of august and received an appointment for 9/14, 3 weeks away. I grew concerned with my families safety each drive and began reaching out to other dealers (2+ hrs away). My pathfinder was taken to a dealer 9/4/20. Diagnosed with timing chain, guide, tensioner issues. Estimate $3100. It has been there 2 weeks today and they are still unable to get parts needed for repair and are unable to determine when this will happen. My families only vehicle, less than 3 years old, 75,000 miles. Nissan refuses to help at all.

My vehicle received a check engine light. I took my vehicle into a dealership and they informed me that there was an issue with the fuel system. Nissan apparently knows about this issue and have no idea on how to fix it. They recommended that I keep the car filled to half a tank or more so I do t get the check engine light. The issue I have is in the occasion I let the car get below half a tank and the check engine light comes on how can I tell if it's the fuel system or something else. It takes approximately a week or more for the light to go off after refilling the car. My vehicle has been like this for just over a year. I've asked repeated times for an update with no answer.
