A fresh Consumer Reports analysis paints a troubling picture of declining vehicle dependability, with modern cars averaging about 204 problems per 100 vehicles after three years of heavy use. Electronics—from infotainment screens to navigation systems—account for many of the glitches.

The Audi Q4 e-tron is a standout in the wrong way. The German electric SUV has generated complaints over electrical component issues that undermine both safety and passenger comfort.

Transmission troubles have cost the Chevrolet Equinox its recommended status. Owners report sudden automatic gearbox failures, harsh shifting, and other drivability headaches. The same kind of transmission woes also plague the Chrysler Pacifica, GMC Terrain, and Ford Explorer, chipping away at everyday usability.

Genesis says it has already addressed the core defects that affected its GV60 and GV80 electric crossovers. But several General Motors models continue to draw fire. Drivers of the Chevrolet Traverse, GMC Acadia, and Buick Enclave regularly experience failures in their all-wheel-drive systems—a safety concern that has left many owners frustrated.

In contrast, Japanese brands continue to set the standard for reliability. Toyota, Subaru, Lexus, and Honda recorded the lowest failure rates in the study, with their electronic systems holding up well even after years of active use.
