2014-2020 Nissan 370Z Steering Column: The Steering Lock Failure and Clock Spring Guide

Key Symptoms of a Failing 370Z Steering Column

Problems with the 370Z steering column usually show up as distinct electrical faults or noises. Here are the most common issues owners experience.

1. Car Won't Start and 'KEY' Light is On

This is the most notorious and serious symptom, almost always caused by a failure of the Electronic Steering Column Lock (ESCL) module. When you try to start the car, the ignition may not even switch to accessory mode, and the engine will not crank. A yellow or orange 'KEY' light often appears on the dashboard. This happens because the anti-theft system doesn't get the correct signal from the ESCL, and it prevents the car from starting, thinking it's being stolen. The failure can be intermittent at first but typically becomes permanent, leaving you stranded.

2. Airbag (SRS) Warning Light is On

An illuminated airbag light is a serious safety concern and a very common sign that the clock spring has failed. The clock spring is a coiled ribbon of wires that maintains the electrical connection to the driver's airbag. Over time, with the constant turning of the steering wheel, these wires can break. When the system detects this broken connection, it turns on the warning light and, crucially, disables the entire airbag system.

3. Steering Wheel Buttons or Horn Don't Work

If your cruise control, audio volume, or phone buttons on the steering wheel stop working, the clock spring is the primary suspect. Since the clock spring provides the electrical connection for all these functions, a break in its internal wiring will cause them to fail, often at the same time.

4. Clicking or Grinding Noise When Turning the Wheel

A distinct clicking, scraping, or grinding sound that occurs only when you turn the steering wheel often points to a mechanically broken clock spring. The internal ribbon cable may have snapped or the plastic housing may have cracked, causing parts to rub against each other inside the column.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

Electronic Steering Column Lock (ESCL) Failure

The most significant known issue for the Nissan 370Z is the failure of the ESCL module. While a major service campaign (ID P3208) was issued for 2009-2010 models, the problem can still occur on later model years, including the 2014-2020 range. The failure is often due to a manufacturing issue, sometimes related to excessive oil inside the unit, which prevents the engine from starting. This is not a safety recall because it does not affect the car while it is running. Many owners, as a preventative measure, choose to pull the 10A "Steering Lock" fuse located in the fuse box near the battery. This must be done while the steering is in the unlocked position. Pulling the fuse disables the lock permanently, preventing it from failing in the locked state and stranding the driver.

Recalls

As of early 2026, there are no major recalls specifically for the steering column assembly on 2014-2020 Nissan 370Z models in the US market. A small recall was issued for eight 2020 370Z and GT-R vehicles due to a potential defect in the front steering knuckle or rear axle housing, which could cause the steering wheel to go off-center or, in a worst-case scenario, a wheel to separate. However, this is unrelated to the common column failures.

Buying a Used 2014-2020 370Z Steering Column

Purchasing a used OEM steering column is often the most cost-effective solution, but careful inspection and verification are key to getting a good part. The assembly typically includes the upper column, lower shaft, and the combination switch.

1. Verify Compatibility

VIN is King: Always provide your VIN to the seller to ensure an exact match. There are variations between trim levels, especially for Nismo models, and production date changes. The main column for non-Nismo models from November 2013 onward is often part number 48810-3GY1A.
Check Part Numbers: The steering column is an assembly of several parts. Key numbers to know are:

• 48810-3GY1A: The main upper steering column assembly.
• 25560-3GY0E: The combination switch assembly (includes clock spring, turn signal/wiper stalks). This part is for non-Nismo models built from 11/2013.
• D8700-JF00D: The part number for the ESCL module in the earlier service campaign. While later models may have an updated part, ensure the used column includes a functional ESCL if you don't plan to bypass it.

2. Physical Inspection Checklist

• Clock Spring Connectors: Carefully inspect the yellow airbag connectors and other plugs on the clock spring. They should be free of cracks, melting, or corrosion. Damaged connectors are a major red flag.
• Shaft and U-Joints: Check the lower intermediate shaft for any signs of bending or heavy rust. Wiggle the universal joints (U-joints) by hand; there should be no noticeable play or looseness.
• Wiring Harness: Ensure all wiring is intact, with no cut wires or damaged insulation.
• Collision Damage: Avoid any steering column from a vehicle that had a deployed driver's airbag. The force can cause unseen damage to the column itself. Look for scorch marks on the connectors.

3. Why Used OEM is a Smart Choice

For a complex assembly like the steering column, a used OEM part is generally superior to a new aftermarket one. Fitment is guaranteed, and the electronics, particularly the clock spring and sensors, are designed to integrate perfectly with your car's SRS and BCM (Body Control Module). Cheap aftermarket clock springs are notorious for causing persistent airbag lights and failing quickly.

Replacement Overview & Difficulty

Replacing the steering column is a moderately difficult job that can be done by an experienced DIY mechanic.

• Difficulty Rating: 3 out of 5
• Estimated Time: 2-3 hours
• DIY Feasible: Yes, for those comfortable with interior work and safety procedures.

High-Level Steps:

1. Disconnect the negative battery terminal.
2. Straighten the front wheels and lock the steering wheel in place.
3. Remove the side trim pieces and the T30 Torx bolts holding the airbag module to the steering wheel.
4. Carefully unplug the airbag connectors and set the airbag aside in a safe place, face up.

5. Remove the 19mm center nut and use a steering wheel puller (or careful wiggling) to remove the steering wheel.
6. Remove the plastic column shrouds and lower dash panels.
7. Disconnect all electrical connectors for the clock spring, combination switch, and ESCL module.
8. Unbolt the column from the dash support bracket and the pinch bolt at the lower U-joint.
9. Installation is the reverse of removal. Ensure the steering wheel and clock spring are centered correctly to avoid damage.
