Repainting a Bumper and Sensor Calibration
How a bumper repaint over parking sensors causes false alerts, why thick paint degrades ultrasonic and radar signals, and the recalibration fix.

Warning system
Almost every driver-assist feature leans on a handful of cameras and radar units, so this section is the hardware backbone of the site. When a windshield camera fogs up, a radar sits behind a fresh coat of touch-up paint, or an ultrasonic parking sensor fills with ice, several warnings can appear at once. Here you will learn where each sensor lives, what obstructs it, and why calibration matters so much after a repair. The guides explain static versus dynamic calibration in plain terms, show how to clean sensors without damaging them, and help you understand quotes before you agree to any work. If a cluster of warning lights came on together, this is the place to start.
