The 2013 Nissan Skyline (V36 chassis) is a solid rear-drive sedan sharing platforms with the Infiniti G37, but timing chain wear and transmission cooling issues are the Achilles' heels that can turn expensive fast if ignored.
Symptoms: Cold-start rattle lasting 3-5 seconds that goes away when warm, Check engine light with P0011/P0021 cam timing codes, Rough idle and hesitation under acceleration, Metallic scraping noise from front of engine at startup
Fix: Complete timing chain kit replacement including guides, tensioners, and both chains. Requires front engine teardown, 12-16 labor hours. VQ35HR is worse than VQ25HR but both suffer this. Catch it early or risk valve-to-piston contact and bent valves requiring head work.
Estimated cost: $2,200-3,800
Transmission Oil Cooler Failure (7AT)
Common · high severity
Typical onset: 70,000-110,000 mi
Symptoms: Transmission fluid leaking from radiator area, Milky or strawberry-colored transmission fluid (coolant cross-contamination), Harsh shifting or slipping after cooler fails internally, Overheating transmission temp gauge readings
Fix: The internal cooler in the radiator fails and mixes coolant with ATF, destroying the transmission if not caught immediately. Replace radiator, flush entire cooling system AND transmission, replace ATF and filter. If contamination sat more than a day of driving, budget for transmission rebuild. 6-8 hours labor for cooler/flush, add 18-24 hours if trans needs rebuild.
Estimated cost: $1,200-2,000 (cooler only), $4,500-6,500 (with trans rebuild)
Transmission Mount Collapse
Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunk when shifting from Park to Drive or Reverse, Vibration felt through center console at idle, Excessive drivetrain movement visible when revving in Park, Transmission tunnel heat increase from exhaust contact
Fix: Rubber transmission mount deteriorates and allows excessive movement, sometimes letting trans contact tunnel or exhaust. Replace mount, 2-3 hours labor. Inspect for heat damage to surrounding components if caught late.
Estimated cost: $350-600
Hydraulic Valve Lifter Tick & Failure
Occasional · medium severity
Typical onset: 90,000-150,000 mi
Symptoms: Persistent ticking noise from valve cover area that doesn't go away when warm, Loss of power and misfires on specific cylinders, P0300-series misfire codes pointing to one or two cylinders, Noise worsens over weeks/months
Fix: VQ engines use hydraulic lifters that can collapse or wear, especially if oil changes were skipped. Requires valve cover removal to replace affected lifters, 4-6 hours labor. Often find multiple lifters need replacement once you're in there. Critical: use OEM lifters only, aftermarket fail quickly.
Estimated cost: $800-1,400
Fuel System Clogging & Filter Issues
Occasional · medium severity
Typical onset: 80,000-120,000 mi
Symptoms: Rough running and stalling at idle after fuel level drops below 1/4 tank, Long cranking before engine starts, Hesitation and stumbling under throttle, P0171/P0174 lean codes
Fix: Fuel filter (in-tank as part of pump assembly) clogs from tank sediment. Many owners also find tank contamination from bad gas or rust. Drop tank, replace pump assembly with filter, inspect/clean tank. 4-5 hours labor. If pump motor is weak, replace entire assembly.
Estimated cost: $600-1,100
Radiator & Cooling System Leaks
Occasional · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Coolant smell from engine bay after driving, Slow coolant loss requiring top-ups every few weeks, Visible leaks from radiator end tanks (plastic-to-aluminum junction), Overheating in traffic or hot weather
Fix: Radiator end tanks crack at crimps, common failure point. Replace radiator (NOT just the trans cooler issue above, though do both at once if cooler also failed). 3-4 hours labor. Check hoses and water pump while you're in there.
Estimated cost: $500-900
Owner tips
Change transmission fluid every 30,000 mi regardless of 'lifetime fill' claims — it's cheap insurance against cooler contamination damage and extends 7AT life significantly
Use quality 5W-30 synthetic and keep oil change intervals at 5,000 mi MAX to preserve timing chain and lifters — these VQ engines are very oil-change sensitive
Listen for cold-start rattle religiously; if you hear it more than 2 seconds, budget for timing chains NOW before it grenades
Install an auxiliary transmission cooler if you live in hot climates or tow anything — takes load off the failure-prone internal radiator cooler
Check transmission fluid color monthly; any pink/milky appearance means immediate shutdown and tow to shop
Buy one if timing chains and trans cooler have already been done with receipts, or if you're handy and budget $4K-5K for deferred maintenance — otherwise, find an Infiniti G37 with better service history for the same money.
