2022 Volkswagen Passat Brakes Problems

Your car's brake calipers have repeatedly seized since new, causing uneven brake wear and dragging noises. The front brakes appear to have never engaged properly (front pads still factory original at 115,000 miles), while rear pads wear completely, and you've had multiple seized calipers and a failed ABS module requiring replacement. A brake caliper inspection and potential replacement of the calipers and guide pins, along with a thorough brake system diagnostic, may be needed to restore balanced braking.

Your brake pads are wearing unevenly across all four corners of your car. The rear brake calipers have stuck multiple times, causing one pad to wear down completely while the other stays fresh, and you've had to replace rotors and pads out of pocket twice despite warranty coverage initially. Your front brake pads show almost no wear even at 80,000 miles, which is unusual. The dealer eventually identified a defective ABS module as the likely cause, but you're concerned about the safety and reliability of the braking system given the pattern of uneven wear and repeated failures. Fixing this will require replacing the ABS module, rear brake pads, and rear rotors, and may require further diagnosis to ensure all brake components are functioning properly.

Your rear brakes are wearing out much faster than normal—measuring at only 2mm thickness with just over 20,000 miles on the vehicle. The dealership attributed this to the Passat being "hard on rear brakes," but you didn't experience this problem with your previous Passat, and your husband's Taos from the same model year is experiencing the same issue. This premature wear is unsafe and unreasonable compared to typical brake life expectancy. A solution may involve inspecting the brake system for design issues, replacing the brake pads and rotors, and having the braking system professionally evaluated.
