C1A14 on Lexus
Front Radar Sensor Beam Axis Not Adjusted
C1A14 on Lexus vehicles indicates front radar sensor beam axis not adjusted. Au7o has documented this code across 1 Lexus model — most commonly on RX. C1A14 is a manufacturer-specific chassis code (documented on Nissan/Infiniti) indicating the front radar sensor's beam axis (aim) has not been adjusted or calibrated. This radar sensor supports advanced driver-assistance features such as adaptive cruise control and forward collision warning/automatic braking. When the sensor is misaligned or its alignment has not been completed, the module disables those ADAS features and sets the code. Often appears after a front-end repair, windshield/bumper work, or a collision. Confirm against the factory manual. Typical repair costs on Lexus range from $250 to $1,800, depending on the specific model and root cause.
Common Causes of C1A14
- •Radar sensor not calibrated/aligned after service
- •Sensor or bracket physically misaligned
- •Front-end collision or bumper/grille repair
- •Damaged sensor or mounting bracket

These complaints appear in NHTSA filings and owner forums, often after windshield replacement, minor impacts, heavy rain, or sometimes with no obvious trigger.
