Short version: the hybrid half of that warning is mostly outdated, and the sensor half is partly true but usually exaggerated.
On hybrids, the evidence points the other way. Regenerative braking means the electric motor does most of the slowing, so friction pads and rotors commonly last 70,000 to 100,000 miles or more - many owners never replace pads in the time they keep the car. You also skip a conventional starter and alternator, and there's no separate transmission service on most hybrids. Consumer Reports' survey data has found traditional hybrids average about 15 percent fewer problems than gas-only cars. One caveat: plug-in hybrids are a different story in the same surveys, showing noticeably more problems than gas-only models, so "hybrid" isn't one uniform thing. The costs that do exist are ordinary ones - oil changes, coolant, and brake fluid roughly every couple of years. Oddly, the biggest hybrid brake risk is underuse: lightly used brakes can corrode or stick, so have them inspected. And the high-voltage battery is usually covered for a long time - federal rules set a minimum of 8 years/100,000 miles, and some brands go further (Toyota, for example, covers hybrid batteries 10 years/150,000 miles on 2020-and-newer models).
On driver-assist sensors, the sensors themselves aren't a scheduled maintenance item and rarely just "wear out." The real cost is event-driven: glass and collision repairs. AAA's 2023 study found that on a windshield replacement, relocating the cameras and recalibrating averaged about $360, roughly a quarter of a $1,440 total repair estimate, and that ADAS parts in a minor rear impact averaged about $685, about 41 percent of a $1,700 estimate. Calibration alone typically runs somewhere in the $150-$400 range at independent shops, with dealers often starting around $400-$500 or more, depending on the vehicle and whether it needs static, dynamic or both. Those are real numbers - but they're repair bills, not annual upkeep, and glass and collision claims are often where insurance helps.
So: is it scare tactics? Partly - but not entirely invented. Hybrids are the safer bet of the two. The honest advice is to check two things before you decide on any extended warranty: exactly what your factory coverage already includes (especially hybrid components and battery), and whether your insurance glass coverage pays for recalibration, since skipping calibration after a windshield is a bad idea. Extended service contracts commonly run $2,000 or more, so compare a few quotes and read the exclusions - wear items and sometimes calibration work aren't covered.
Costs vary a lot by brand, model and region, so treat these as ballpark figures rather than quotes. If you tell me the specific vehicle you're considering, I can narrow it down.
