What is the 2003-2009 Nissan 350Z Steering Lock Module and NATS Immobilizer Failure?

The 2003-2009 Nissan 350Z experiences failures of the NATS (Nissan Anti-Theft System) immobilizer and steering lock module. The NATS antenna ring around the ignition cylinder fails to communicate with the key transponder, causing intermittent no-start conditions. The ECU can ente… Repairs typically run $300-$1,900. Severity: high.

What is the 2003-2004 Nissan 350Z Fuel Filler Hose Cracking and Leaking During Refueling (Recall 05V555000)?

The rubber fuel filler hose between the filler neck and the tank can crack, letting fuel leak while the car is being refueled. With an ignition source nearby this is a fire risk. Nissan recalled 2003-2004 350Z under NHTSA campaign 05V555000 as part of a large multi-model action c… Repairs typically run $0-$350. Severity: high.

What is the 2003-2006 Nissan 350Z Fuel Pressure Damper Diaphragm Failure — Engine-Bay Ticking and Fuel Seepage?

The fuel pressure dampers sit on the fuel rails to smooth injector pulsations. The internal diaphragm fails, first producing a distinct ticking or light knocking noise from the top of the engine at idle that owners routinely mistake for injector or valvetrain noise, and then allo… Repairs typically run $100-$400. Severity: high.

What is the 2005-2006 Nissan 350Z VQ35DE Rev-Up Engine Oil Consumption?

The revised VQ35DE "Rev-Up" engine (2005-2006 350Z, also known as the VQ35DE Rev-Up) is notorious for excessive oil consumption, often burning 1 quart every 1,000-2,000 miles. The issue is caused by defective galley gaskets (oil passage o-rings) that leak oil internally. The stan… Repairs typically run $500-$3,000. Severity: high.

What is the 2003-2004 Nissan 350Z Front Tire Feathering and Rapid Irregular Tire Wear from Suspension Geometry (2003-2004)?

Early Z33s chew through front tires with a sawtooth 'feathered' wear pattern that produces a loud tire roar, often destroying a set of tires in well under 15,000 miles. The car is extremely sensitive to alignment settings, and under braking and cornering the multi-link geometry m… Repairs typically run $150-$900. Severity: medium.

What is the 2003-2004 Nissan 350Z Early 6-Speed Synchro Wear — Grinding Into 3rd and 5th Gear (2003 to early 2004)?

The 2003 and early 2004 six-speed manual is known among owners for weak 3rd and 5th gear synchros. The box grinds or crunches on the shift into those gears, worst when the transmission is cold and easing somewhat as the fluid warms — the opposite of a simple fluid problem, and it… Repairs typically run $150-$2,000. Severity: medium.

What is the 2003-2009 Nissan 350Z Differential Mount Bushing Tearing — Driveline Clunk and Shudder?

The Z33 rear differential is located by fluid-filled (silicone) rubber mount bushings. Those bushings tear — quickly on cars driven hard, tracked or making more than stock power, and eventually on all of them with age — letting the differential move fore and aft under torque. The… Repairs typically run $250-$900. Severity: medium.

What is the 2004-2009 Nissan 350Z Roadster Power Top — 5th Bow Motor and Multi-Motor System Failure?

The 2004-2009 350Z Roadster power top is not a hydraulic system; it is a network of five separate electric motors plus limit switches and sensors that must all report correctly before the top will cycle. The 5th bow motor is the recognised weak point — it uses the same brush desi… Repairs typically run $300-$2,500. Severity: medium.

What is the 2003-2009 Nissan 350Z Front Compression (Tension) Rod Bushing Tearing — Front-End Clunk and Caster Drift?

The front compression rod, which controls fore-aft location of the front hub, is located by a soft rubber bushing designed around stock ride height. It tears — universally on lowered cars, because the rod no longer sits level and the bushing is stretched at rest, and eventually o… Repairs typically run $200-$800. Severity: medium.

What is the 2003-2009 Nissan 350Z Rear Quarter Panel and Wheel Arch Corrosion — Paint Bubbling From the Inside Out?

Z33 rear quarter panels and wheel arch lips corrode from behind, so the first sign is paint blistering or bubbling along the arch lip, at the seam where the quarter meets the rear bumper, and around the antenna base. Owners report it on low-mileage cars — including a 2003 with ar… Repairs typically run $400-$3,000. Severity: medium.

What is the 2003-2009 Nissan 350Z Power Window Regulator and Motor Failure?

The 350Z's power window regulators fail frequently, with the window falling into the door or moving slowly/erratically. The window motor wears out and the regulator cable frays or the gear mechanism strips. The frameless door design means a failed window cannot seal properly, all… Repairs typically run $100-$400. Severity: medium.

What is the 2003-2006 Nissan 350Z Excessive Oil Consumption (Pre-Revision VQ35DE)?

Early 350Z models (2003-2006) with the pre-revision VQ35DE engine consume oil excessively, often 1 quart every 1,000-2,000 miles. The issue is caused by thin piston rings and a catalytic converter design that pulls oil through the PCV system. Nissan revised the engine in 2005 (Re… Repairs typically run $50-$3,000. Severity: medium.

What is the 2003-2009 Nissan 350Z Xenon HID Headlight Ballast and Igniter Failure?

The factory xenon headlamps on HID-equipped Z33s fail at the ballast or the igniter rather than the bulb. The ballast steps 12V up to the striking voltage and the igniter supplies the initial arc; as either degrades the lamp flickers, buzzes, dims, shifts colour toward pink or pu… Repairs typically run $150-$600. Severity: low.
