All 3 Known Issues
On the 2003-2009 Nissan 350Z, 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 enter lockout mode after repeated failed start attempts. Additionally, the mechanical steering lock can bind, preventing key insertion or rotation. These issues leave the vehicle completely inoperable until repaired. The NATS system requires dealer-level diagnostic equipment (Nissan CONSULT) for reprogramming, making roadside repair impossible.
Common Symptoms
- Engine cranks but does not start (NATS lockout)
- Security indicator light flashing rapidly on dashboard
- Key will not turn in ignition cylinder
- Steering wheel locked and cannot be released
- Intermittent starting failures that worsen over time
- Whining noise near driver fuse box area

On the 2003-2009 Nissan 350Z, 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, allowing rain intrusion. Driver's side fails more frequently due to higher usage.
Common Symptoms
- Window falls into door
- Window moves slowly or in jerky motions
- Grinding noise from door when operating window
- Window stops partway and reverses
- Clicking sound but window doesn't move
How to Fix
Replace the window regulator and motor assembly ($100-$200 for aftermarket, $250-$400 OEM). The repair requires removing the door panel and disconnecting the window from the regulator track. Re-initialize the auto-up/down feature after installation by holding the switch in the full-up position for 3 seconds after the window reaches the top. Apply white lithium grease to the window tracks.

- TipGet the regulator WITH the motor as an assembly — the motor alone usually isn't the issue, it's the cable or gear mechanism. A quality aftermarket assembly from Dorman is $100 and takes an hour to install.

On the 2003-2009 Nissan 350Z, the 350Z power window regulators are a common failure item, with the cable-driven mechanism breaking or the motor failing. The driver-side window regulator fails most frequently due to higher usage. When the regulator fails, the window either drops into the door, becomes stuck in position, or operates very slowly. The 350Z window regulator is a known weak point across all model years (2003-2009). The frameless door glass design puts more stress on the regulator mechanism.
Common Symptoms
- Window drops into door suddenly
- Window moves very slowly or intermittently
- Grinding or clicking noise when operating window
- Window stuck in down position
- Window tilts or binds during operation
How to Fix
Diagnose by removing the door panel and vapor barrier, then checking for a frayed/broken regulator cable, loose glass attachment, or a weak/inoperative window motor while verifying power and ground at the motor connector. On the 350Z, the usual repair is replacement of the complete window regulator assembly, often with the motor if operation is slow or intermittent; after installation, align the glass carefully in the tracks and perform the power window auto-up/down initialization procedure so the frameless glass indexes correctly. Use an OEM or high-quality aftermarket regulator, as cheap units often fail early. Typical parts cost is about $120-$250 for the regulator, $80-$180 for a motor if needed, and total installed cost is commonly $300-$600 per door.
