Short answer: your gut and your friends are each right about different parts of the bill. Hybrids usually win on running costs but not on purchase price, and driver-assist tech is mostly a repair-bill risk rather than a maintenance cost.
On hybrids. You'll pay more up front. Kelley Blue Book's 2026 example puts a Toyota Corolla LE at $24,595 versus $25,970 for the hybrid — about 5.5% more. At 15,000 miles a year, the hybrid saved roughly $459 in fuel, so payback was around three years. Other sources cite average premiums of about $1,300 for a hybrid car and up to $3,000 for a hybrid SUV. So if you keep the car a long time and drive a lot of city miles, the math usually works; if you trade every three years or do mostly highway miles, it often doesn't.
Routine upkeep is genuinely a bit cheaper. Hybrids typically go 7,500–10,000 miles between oil changes instead of 5,000–7,500, and regenerative braking means brakes last much longer. Some dealers charge $100–$200 for hybrid system inspections at service visits, which partly offsets that.
The scary item is the high-voltage battery. A dealer quote can run $2,000–$8,000, while independent specialists often do remanufactured packs for roughly $1,000–$3,000 depending on the model. Important caveat: it isn't a scheduled replacement item. Most packs last well over a decade, and a warning light doesn't automatically mean a new pack. I'd budget it as a possible one-time cost if you plan to keep the car past 12–15 years, not as an annual expense.
On driver-assist tech, your instinct has real evidence behind it. AAA's 2023 study found ADAS can add up to 37.6% to repair costs after a crash, and individual sensor components ran $290–$1,596 in parts and labor. In their scenarios, ADAS parts added about $1,540 to a minor front hit and about $684 to a minor rear hit. A windshield replacement with a camera behind the glass plus recalibration was cited around $1,500 versus roughly $210–$300 for plain glass. The extra cost is mostly calibration — cameras and radar have to be realigned after glass work, alignment, or any bump.
The tech itself doesn't usually break on a schedule, but it makes ordinary accidents more expensive. Most comprehensive and collision policies do cover calibration as part of a covered repair, though shops report insurers pushing back on documentation. I can't give you a reliable figure for how much your specific premium would change — that varies too much by insurer, model, and state, so it's worth asking your agent directly.
One more thing: none of these numbers are model-specific, and prices vary a lot by region and by car. If you tell me which two or three vehicles you're actually comparing, I can get much closer on the real five-year cost.
