Emergency: How to Start an INFINITI with a Failed Steering Lock
If your INFINITI (common on 2009-2012 G37, M35, and QX models) won't start, the steering wheel is locked, and the "Key" warning light is on, your Electronic Steering Column Lock (ESCL) has likely failed in the "locked" position.
1. What are the symptoms of a failed Steering Lock Control Unit?
The most common symptom is a "No Start, No Crank" condition where the dashboard lights up, but the ignition stays in 'LOCK' or 'ACC' mode. You will often see a yellow or red "Key" icon on the instrument cluster, and the steering wheel will be physically impossible to turn.
2. Can I pull a fuse to fix the INFINITI steering lock?
There is a popular "preventative" fix: once you successfully get the car started using the tap method, many enthusiasts pull the Steering Lock Fuse (typically a 10A fuse in the IPDM unit under the hood) while the car is in the 'ON' position. This prevents the pin from ever locking again. Note: This is a modification and should only be discussed with a certified technician.
3. Why did INFINITI issue a warranty extension for this?
Due to the frequency of this issue, Nissan/INFINITI previously issued a voluntary service campaign (and in some cases, warranty extensions) for the ESCL. While many of these extensions have expired, it is always worth checking your VIN with our service department to see if your specific vehicle has open recalls or "Goodwill" repair opportunities for the steering lock unit.
4. What is the permanent fix?
The only permanent, safe solution is to replace the Steering Lock Control Unit (Part #48700-1NC1A or similar). At INFINITI of Beachwood, we use the updated "Revision C" parts which were redesigned by the manufacturer to prevent the internal motor binding that caused the original failures.
