The 2022 NP300 is a workhorse truck still using older Nissan platforms—the QR25DE gas and YS23 diesel have both been around, but timing chain and lifter issues on the gas motor plus transmission cooling problems plague these trucks earlier than you'd expect for a 2022.
Timing Chain Stretch and Tensioner Failure (QR25DE Gas)
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: cold-start rattle that lasts 5-10 seconds, check engine light with P0011/P0021 cam correlation codes, rough idle and loss of power, metallic rattling under acceleration
Fix: Full timing chain kit replacement including guides, tensioners, and both camshaft sprockets. 8-10 hours labor. If you wait too long, the chain can jump and you're looking at valve-to-piston contact and a full head rebuild or engine replacement.
Estimated cost: $1,800-3,200
Hydraulic Lifter Collapse (QR25DE Gas)
Common · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: ticking or tapping noise from valve cover, loudest at idle, noise may quiet down when warm, occasional misfire codes, loss of power on one or more cylinders
Fix: Replace all lifters as a set—doing one at a time just kicks the can. Remove camshafts, inspect cam lobes for wear. 6-8 hours labor. Often done alongside timing chain work if you're already in there.
Estimated cost: $1,200-2,000
Transmission Oil Cooler Line Leaks
Occasional · high severity
Typical onset: 50,000-90,000 mi
Symptoms: transmission fluid pooling under truck, burnt transmission fluid smell, slipping or delayed shifts, transmission overheating warning on dash
Fix: Replace cooler lines and often the external oil cooler itself due to internal corrosion. Flush transmission after repair. 3-4 hours labor. Ignore this and you'll cook the transmission in short order.
Estimated cost: $600-1,200
Harmonic Balancer Separation (QR25DE Gas)
Occasional · high severity
Typical onset: 80,000-130,000 mi
Symptoms: vibration at idle that worsens with RPM, serpentine belt walking off or shredding, wobbling crankshaft pulley visible during inspection, check engine light with crank position sensor codes
Fix: Replace harmonic balancer and inspect crankshaft nose for damage. If the rubber ring separates completely, it can take out the crank sensor, alternator, and A/C compressor. 2-3 hours labor.
Estimated cost: $400-800
Head Gasket Failure (YS23 Diesel)
Occasional · high severity
Typical onset: 90,000-150,000 mi
Symptoms: white smoke from exhaust, coolant loss with no visible leaks, overheating under load, milky oil on dipstick or oil cap, rough running and misfires
Fix: Head gasket replacement with cylinder head resurfacing. Check for cracks and warpage—diesel heads are notorious. 12-15 hours labor. If you catch it early, head usually survives; wait too long and you're into full head replacement or rebuild.
Estimated cost: $2,500-4,500
Transmission Mount Failure
Common · low severity
Typical onset: 40,000-80,000 mi
Symptoms: clunking when shifting into drive or reverse, excessive vibration through cab at idle, visible cracking or separation in rubber mount, transmission sag visible from underneath
Fix: Replace transmission mount. Simple job if you have a transmission jack—1.5-2 hours labor. Use OEM or quality aftermarket; cheap mounts fail in 20k miles.
Estimated cost: $200-400
Fuel Filter Clogging (YS23 Diesel)
Common · medium severity
Symptoms: hard starting especially in cold weather, loss of power under load, surging or hesitation at highway speeds, limp mode activation
Fix: Replace fuel filter every 15,000-20,000 miles religiously on the diesel. Poor fuel quality accelerates clogging. Also replace water separator. 1 hour labor. Skipping this maintenance is the fastest way to kill your high-pressure fuel pump at $2,500+.
Estimated cost: $150-300
Owner tips
QR25DE owners: use quality synthetic oil and change every 5k miles max—this engine is brutal on oil and sludge accelerates timing chain and lifter wear
Inspect timing chain tensioner and guides at 60k miles even if no noise—preventive replacement is way cheaper than engine damage
YS23 diesel owners: religious fuel filter changes and use diesel additive in winter to prevent gelling and injector carbon buildup
Check transmission cooler lines during every oil change—catch seepage before it becomes a leak
Avoid extended idle time with these engines—they're designed for work, and long idles accelerate carbon buildup and oil degradation
Buy one used only if it has documented timing chain replacement (gas) or pristine maintenance records (diesel), and budget $2k-3k for deferred engine work in the first year—these are tough trucks but the engines have known weaknesses that previous owners often ignore.
