Steering Column Spiral Cable Weld Failure
The electrical connection inside the steering column's spiral cable assembly may be insufficiently welded, causing the connection to separate. If the spiral cable fails, the driver's airbag is deactivated and the horn may become inoperative, significantly reducing occupant protection.
Lexus issued a recall to inspect and replace the spiral cable assembly as necessary, free of charge. Contact your dealer to check if your VIN is affected. Do not delay this repair as it directly affects airbag functionality.
