Radar sensor out of alignment
A radar sensor aimed a few degrees away from where the module believes it points. Aim is part of the calibration, not a detail: the module knows what the sensor should see when the car travels straight, and a geometry that no longer matches produces readings it rejects from hardware that is working perfectly.
Bumper work is the usual trigger — these sensors mount behind plastic skins, and a bumper refitted a few millimetres out, a bracket bent in a car-park knock, or accident repair at either end is enough. Replacing the sensor without re-aiming it reproduces the fault with a new part.
The repair is a calibration procedure, usually requiring targets at measured distances on level ground, and it is the step most often skipped.
Typically specialist work. Needs equipment or training most home workshops do not have.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
