The 2017 Nissan NP300 with QR25DE engine is a workhorse pickup popular in many markets, but it suffers from a known timing chain premature wear issue and transmission cooling problems that can lead to expensive failures if not addressed early.
Timing Chain Stretch and Guide Failure
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Rattling noise on cold start that disappears after warmup, Check engine light with P0011/P0021 VVT codes, Rough idle or hesitation, In severe cases: sudden loss of power or no-start condition
Fix: Complete timing chain kit replacement including guides, tensioners, and both chains. Requires 8-12 hours labor as front cover must come off. Oil pump chain often replaced simultaneously. Critical to catch early before guides break and cause catastrophic engine damage.
Estimated cost: $1,800-3,200
Transmission Oil Cooler Line Leaks and Cooler Failure
Common · high severity
Typical onset: 70,000-120,000 mi
Symptoms: Red fluid puddles under vehicle, Transmission overheating warnings, Harsh shifting or slipping when towing/loaded, Pink residue around cooler connections
Fix: Replace oil cooler and/or lines. Cooler itself typically 3-4 hours, lines alone 1-2 hours. Must flush transmission system if contamination occurred. Failure often cascades into full transmission damage if ignored, as cooler debris enters valve body.
Estimated cost: $600-1,400
Hydraulic Lifter Collapse and Noise
Occasional · medium severity
Typical onset: 80,000-140,000 mi
Symptoms: Persistent ticking or tapping from valve cover area, Noise increases with engine load, Does not go away after warmup unlike timing chain rattle, Possible misfire codes on affected cylinders
Fix: Replace all lifters as they typically fail in batches. Requires cylinder head removal to access lifters properly (10-14 hours labor). Often combined with timing chain service if both are suspect. Replace valve cover gasket and cam seals during reassembly.
Estimated cost: $2,200-3,800
Head Gasket Failure with Overheating History
Occasional · high severity
Typical onset: 90,000-150,000 mi
Symptoms: White smoke from exhaust, Coolant loss with no visible leaks, Oil milkshake (coolant in oil), Overheating or bubbling in coolant reservoir, Misfires and rough running
Fix: Head gasket replacement requires cylinder head removal and machining if warped (12-16 hours labor). Always check head flatness and pressure-test. Must replace timing components at same time since they're exposed. Often related to prior cooling system neglect or towing abuse.
Estimated cost: $2,800-4,500
Transmission Mount Deterioration
Common · low severity
Typical onset: 50,000-90,000 mi
Symptoms: Clunk when shifting into drive or reverse, Excessive vibration at idle in gear, Transmission appears to 'drop' when accelerating hard, Visible cracking or separation in rubber mount
Fix: Replace transmission mount. Straightforward job at 1.5-2.5 hours depending on access. Often both engine and transmission mounts are replaced together as they age similarly. Inspect driveline for play while mount is off.
Estimated cost: $250-500
Fuel Filter Clogging (Diesel Variants)
Occasional · medium severity
Symptoms: Hard starting especially in cold weather, Loss of power under load, Surging or hesitation at highway speeds, Fuel starvation symptoms
Fix: Replace fuel filter and bleed system. Takes 1-1.5 hours. In regions with lower-quality diesel, filters clog earlier than service intervals. Water separator should be drained regularly. This mainly applies to diesel markets; gas QR25DE has in-tank filter that rarely fails.
Estimated cost: $150-300
Owner tips
Change oil every 3,000-5,000 miles with quality synthetic to prolong timing chain life — extended intervals accelerate chain stretch on this engine
Service transmission fluid every 30,000-40,000 miles especially if towing; factory 'lifetime' fluid is not realistic for work truck use
Listen for timing chain rattle on cold starts starting at 50,000 miles; early replacement prevents $5,000+ engine rebuilds
Flush coolant every 30,000 miles and inspect radiator/hoses; overheating events rapidly damage head gaskets on QR25DE
If buying used, have pre-purchase inspection specifically check timing chain tension and listen for lifter noise with stethoscope
Reliable workhorse if timing chain is addressed proactively before 80K miles and transmission is serviced regularly; budget $2-3K for inevitable timing work or walk away from high-mileage examples without service records.
