C1A12 on Infiniti
Manufacturer-Specific Chassis Code (Nissan/Infiniti: Radar/Laser Sensor Beam Off-Center)
C1A12 on Infiniti vehicles indicates manufacturer-specific chassis code (nissan/infiniti: radar/laser sensor beam off-center). Au7o has documented this code across 1 Infiniti model — most commonly on QX60. This is a manufacturer-specific chassis code seen primarily on Nissan/Infiniti vehicles, generally associated with the forward radar/laser sensor used by adaptive cruise control and collision-avoidance systems being misaligned or 'off-center.' Because it is not a generic SAE code, the exact meaning can vary by maker and model, but it broadly points to an issue with the driver-assistance/distance sensor or its aim. When set, related systems like intelligent cruise control or forward emergency braking may be disabled. A vehicle-specific service procedure (sensor aiming/calibration) is typically required.
Common Causes of C1A12
- •Misaligned or blocked forward radar/laser sensor
- •Sensor knocked out of aim by minor impact or bumper work
- •Obstruction or dirt over the sensor (snow, ice, debris)
- •Faulty distance/radar sensor
- •Wiring or connector fault at the sensor
- •Sensor calibration not performed after service/alignment

- Forward Collision Warning / Automatic Emergency Braking False Activation or Unexpected Braking2022-2025
Owners have reported unexpected forward collision warnings and abrupt braking events with no obvious obstacle ahead, especially in traffic, on curves, or near roadside objects. These complaints are tied to the QX60's ADAS sensor/camera interpretation rather than a conventional brake hardware fault. Sudden braking can create a rear-impact hazard and is one of the more serious owner-reported safety concerns on the current generation.
