- Oil Consumption: Some earlier models, particularly those with the VQ35DE engine, have reported excessive oil consumption. It’s important to check oil levels regularly.
- Fix: Regularly check oil levels and use high-quality synthetic oil. If consumption is excessive, perform an engine compression test.
- Timing Chain Noise: There were reports of a whining noise from the front of the engine, often due to issues with the timing chain or tensioner.
- Replace the timing chain or tensioner if found faulty. Best handled by a professional familiar with the VQ series engines. Prevent this from happening in the first place by regularly servicing your 350Z with the correct grade oil.
- Fuel Damper: Some owners experienced a ticking noise which was linked to faulty fuel dampers.
- Fix: Replace the faulty fuel damper.
- Synchro Wear: The manual transmission, especially in earlier models, sometimes had issues with the synchronizers wearing prematurely. This led to grinding or difficulty when shifting, particularly into the 3rd and 5th gears.
- Fix: Replace worn synchronizers. To prevent, use high-quality transmission fluid and change at recommended intervals. Synchro wear when inspecting a 350Z may indicate an example that has been thrashed and abused.
- Clutch Issues: Several owners reported issues related to the clutch, including soft or fading clutch pedals and clutch failures, especially in vehicles driven hard.
- Fix: Inspect and adjust the clutch regularly. If pedal feels soft or fades, inspect and possibly bleed the clutch fluid. Replace clutch if necessary.
- Tire Feathering: Some 350Zs experienced abnormal tire wear or “feathering,” especially on the front tires. This could be due to alignment or suspension issues.
- Fix: Regularly check and correct wheel alignment. Address any suspension component issues.
- Paint Issues: There have been reports of paint chipping or peeling more easily than expected, particularly on the front bumper and hood.
- Fix: Use paint protection film. Consider professional repainting if chipping or peeling is significant.
- Convertible Roof Problems: Owners of the roadster version sometimes encountered issues with the convertible top mechanism.
- Fix: Ensure mechanism is free from obstructions and lubricate moving parts. If problems persist, get a professional roof mechanism inspection and replace as required.
- Window Motors: Several owners reported problems with the window motors failing or becoming weak over time.
- Fix: Replace weak or failing window motors.
- Fuel Gauge Misreading: There were instances where the fuel gauge would misread the actual amount of fuel left in the tank.
- Fix: Replace the faulty fuel sending unit.
- Seat Movement: Some drivers noticed that the driver’s seat might move slightly under heavy acceleration or braking, often referred to as “seat click.”
- Fix: Tighten any loose seat mounting bolts. If the issue persists, replace the seat’s mounting mechanism.
- Materials Wear: Over time, some of the interior materials, especially on high-touch areas like the door handles and steering wheel, could show signs of premature wear or peeling.
- Fix: Use quality interior protectants on high-touch areas. Consider professional reupholstering or replacement for significant wear.
Remember, while these issues have been reported by some owners, they don’t represent every Nissan 350Z’s experience. This also isn’t a complete list of everything that “could” go wrong with a 350Z, but more a focus on some of the most common issues.
Regular maintenance, driving habits, and care can have a significant impact on a vehicle’s longevity and reliability. Always consider having any used vehicle inspected by a trusted mechanic before purchasing.
