What is the 2007-2009 Nissan 350Z Concentric Slave Cylinder (CSC) Failure — Clutch Pedal Drops to Floor (VQ35HR 6-Speed)?
The 2007-2009 350Z with the VQ35HR engine uses a CD009 6-speed whose clutch release bearing and slave cylinder are combined into one concentric unit (CSC) mounted inside the bellhousing. Clutch dust contaminates the seal and the plastic/aluminum body fractures, so the hydraulic c… Repairs typically run $900-$2,200. Severity: high.
What is the 2003-2009 Nissan 350Z NATS key-authentication no-start: lock mode or a key-read fault?
The immobilizer checks the registered ignition key before permitting a start. A NATS lock-mode code and a key-read code describe different stages of that check, not a confirmed failed part. Interference, key identification and antenna-circuit faults need to be distinguished. A me… Severity: high.
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 2003-2009 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.
