Jeep Wrangler · 2007–2017
The clockspring (a coiled ribbon-cable assembly behind the steering wheel that maintains electrical continuity to the driver airbag, horn, cruise control, and steering-wheel radio controls while the wheel turns) is a chronic Wrangler failure point, aggravated by off-road dust intrusion and vibration. Dust contamination of the flexible conductor's grease causes it to bend abnormally and the circuits to wear open — most critically the driver-airbag squib circuit, which may not deploy in a crash. NHTSA recall 16V-288 (Safety Recall S40) covered 2011-2016 RIGHT-hand-drive Wranglers; a companion recall covered earlier RHD units, and NHTSA investigated 2007-2012 left-hand-drive Wranglers. For 2011-2016 LEFT-hand-drive Wranglers, FCA did NOT recall but issued Customer Satisfaction Notification X68 (bulletin D-17-01) extending the clockspring warranty to 15 years/unlimited miles due to the failure rate. The airbag circuit can fail while horn/cruise still work, or vice versa.
Common Symptoms
- Airbag / SRS warning light illuminated
- Horn inoperative
- Cruise control inoperative
- Steering-wheel radio/audio buttons not working
- Radio presets changing randomly
- Intermittent operation that worsens after off-road/dusty use
How to Fix
Scan for airbag (SRS) fault codes and inspect the clockspring for dust intrusion and open circuits. Accepted fix is replacement of the steering-column clockspring assembly (recall/warranty repairs also replace the steering-wheel back cover and column shrouds). On recall- or X68-warranty-eligible VINs the dealer performs this free (and reimburses prior paid repairs); otherwise it is a standard clockspring R&R. Keeping the steering-column boot/seals intact helps prevent recurrence on heavily off-roaded Jeeps.
