2014-2018 Jeep Cherokee Clock Spring: Solving the Airbag Light and Failed Controls

Symptoms of a Failing Clock Spring

When the clock spring in a 2014-2018 Jeep Cherokee begins to fail, it typically presents several distinct and noticeable symptoms. Because the internal ribbon cable breaks from the stress of turning, the electrical connections are lost.

• Airbag Warning Light: This is the most common and most serious symptom. A fault in the clock spring breaks the connection to the driver's airbag module, causing the vehicle's Supplemental Restraint System (SRS) to detect a problem and illuminate the airbag light on the dashboard. When this light is on, the entire airbag system is disabled and will not deploy in an accident.
• Inoperative Steering Wheel Controls: Buttons for the cruise control, radio volume, and hands-free phone system may stop working intermittently or fail completely.
• Horn Malfunction: The horn may not work at all, or it might only work when the steering wheel is in a specific position.
• Unusual Noises: You might hear a squeaking, clicking, or grinding noise from the steering column when turning the wheel. This can be a sign that the internal ribbon cable is binding or has broken.

• Traction Control Light: In some cases, a faulty clock spring can interfere with the Steering Angle Sensor (SAS), which can cause the traction or stability control warning light to illuminate.

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

While there are widespread reports of clock spring failures across many Jeep models due to dust ingestion, specific recalls for the 2014-2018 Cherokee (KL generation) are not for the clock spring itself. However, related recalls do exist:

• NHTSA Recall for Unintended Airbag Deployment: A recall was issued for some 2014-2015 Jeep Cherokee models because overly sensitive software could cause the side curtain and seat airbags to deploy unexpectedly. The fix was a software update performed by the dealer. While not a clock spring issue, it's a critical safety check for these model years.
• General Jeep Clock Spring Issues: Other Jeep models, like the Wrangler, had a specific recall (NHTSA 16V-288 / FCA S40) because dust could enter the clock spring and sever the airbag connection. This highlights a known weakness in the part's design across the brand, even if the Cherokee wasn't included in that specific campaign.

You can check for any open recalls on your specific vehicle by entering its 17-digit Vehicle Identification Number (VIN) on the NHTSA website.

Buying a Used 2014-2018 Jeep Cherokee Clock Spring

A used OEM clock spring can be a reliable and cost-effective alternative to an expensive new part. However, careful inspection and verification are essential for this critical safety component.

Inspection and Compatibility Checklist:

• Match Part Numbers Exactly: This is the most important step. Several different clock springs were used in the 2014-2018 Cherokee, depending on factory options. The primary difference is whether the vehicle has a heated steering wheel. You must physically remove your old clock spring and match the Mopar part number on it to the used one you plan to purchase. Common part numbers include 68141120AH and 68141121AH, but many superseded numbers exist.
• Inspect the Connectors: Check that all plastic connectors are intact, with no cracks, broken tabs, or bent pins. The wiring harnesses must plug in securely.
• Check the Ribbon Cable Housing: Look at the main body of the clock spring. It should be free of cracks or signs of physical damage. In some failed units, you can see the tangled or broken ribbon cable through the inspection windows.
• Verify the Centering Lock: A new or properly handled used clock spring will have a plastic tab or lock that keeps it from rotating during shipping and installation. This ensures it is centered. If this lock is missing, the internal ribbon may have been spun too far in one direction and could break immediately upon installation.

Why Used OEM is Often Better Than New Aftermarket

For a safety-critical part like a clock spring, a used OEM (Original Equipment Manufacturer) part is often a better choice than a cheap, new aftermarket unit. OEM parts are built to the vehicle manufacturer's exact specifications for materials and electrical performance. Many aftermarket clock springs, particularly low-cost versions found online, may use lower-quality internal ribbon cables and connectors that can fail prematurely or cause intermittent electrical issues.

Cost of Replacement

The cost to replace a clock spring can vary significantly based on the part source and labor rates. A dealership repair will be the most expensive option.

Installation and Replacement Guide

Replacing the clock spring is a moderately difficult job that can be performed by a skilled DIY mechanic. The primary challenge and risk involve handling the driver's side airbag module.

Installation Difficulty: 3 out of 5

Estimated Time: 1.5 - 2 hours

Basic Replacement Steps:

1. Disconnect the Battery: Disconnect the negative battery terminal and wait at least 2-3 minutes for the airbag system's backup capacitor to fully discharge. This is a critical safety step to prevent accidental deployment.
2. Remove the Airbag Module: There are typically access holes on the back or sides of the steering wheel. Use a tool (like a screwdriver or small rod) to release the spring clips holding the airbag module to the steering wheel.
3. Disconnect and Store the Airbag: Carefully disconnect the electrical connectors from the back of the airbag module. Place the airbag in a safe location with the trim cover facing up.
4. Remove the Steering Wheel: Remove the large center bolt holding the steering wheel. You may need a steering wheel puller tool to free the wheel from the splined shaft.
5. Replace the Clock Spring: Remove the steering column shrouds (plastic covers). The clock spring is now accessible. Disconnect its electrical connectors and unclip it from the steering column. Install the new unit, ensuring it is properly aligned.
6. Reassembly: Reinstall the steering wheel, making sure it is straight. Torque the center bolt to the manufacturer's specification. Reconnect the airbag, reinstall it, and finally, reconnect the battery.
