The failure pattern owners describe
The 2017 Pathfinder's powertrain shows a pattern of early, serious failures that Nissan has not addressed through recalls or extended coverage. The CVT transmission is the most frequent culprit, losing power or refusing to shift into drive at mileages between 25,000 and 90,000 miles—sometimes catastrophically mid-traffic, with owners unable to accelerate or merge safely. Transmission cooler hoses detach due to poor clamping, and codes like P0776 and P17FO suggest chronic pressure and solenoid issues that dealers cannot consistently repair.
Engine problems are equally severe. Metal debris appears in fresh oil shortly after maintenance, followed by complete engine seizure. Owners report low oil pressure warnings despite regular oil changes and proper maintenance. One owner paid $7,000 out-of-pocket for engine replacement; Nissan blamed previous owner maintenance, not design. Timing chains fail around 75,000 miles, causing rattling, surging, and stalling; repair estimates hit $3,100 with parts often unavailable for weeks.
Secondary failures cluster around cooling fans (clanking at 50,000 miles, $600+ replacement), fuel pumps, alternators, and battery systems—all in the first 40,000 miles. Engine hesitation and sluggish acceleration from standstill are common and unresolved. Dealers dismiss throttle and acceleration complaints as normal. Sudden stalling without warning or check-engine codes occurs repeatedly, leaving owners stranded on highways.
Nissan's response has been denial. Out-of-warranty claims are refused; in-warranty repairs sometimes fail to fix the underlying issue, and diagnostic codes often do not appear, preventing resolution. No formal recalls for transmission or engine failures are mentioned in these complaints.

What owners are reporting 4 most recent
The transmission is failing. The car has about 117,000 miles on it. The transmission issue is a known problem with this vehicle and is causing safety concerns while driving it due to acceleration problems.
The Check Engine light turned on and took it to dealership on 12/14/24 and they stated that Throttle chamber may have issues. Used scanner and code P0101- Mass Air Flow Sensor Circuit was read on scanner. Vehicle struggles to get air flow into engine causes speed to struggle when trying to accelerate.
I was driving the car on a city street, all of a sudden car started to slowdown and showed low battery sign and got stopped/turned off.
We own a 2015 and a 2017 platinum pathfinder both with 25k miles. The 2017 has 20-30 more horsepower than the 2015, but the 2017 is much slower. The 2017 is very sluggish from 0-35mph. The acceleration has progressively gotten worse. I've put the highest octane in as instructed by nashville Nissan; still slow. Accelerating uphill at low rpms makes the engine rattle (able to hear it when driving…
