Fair question, and the warnings are half right. Here's the realistic split.
On the hybrid side, routine maintenance usually costs the same or a little less than a comparable gas car. The engine runs less and often shuts off at stops, so oil changes and general engine wear tend to be a bit gentler, and regenerative braking means brakes last considerably longer — many hybrid owners go well past 100,000 miles before their first brake job. Consumer Reports and several ownership-cost analyses have put hybrid maintenance at roughly half the cents-per-mile of a conventional gas car, which works out to a few hundred dollars a year in your favor rather than against you. Where hybrids do bite is repairs, not maintenance: hybrid-specific parts like the battery pack, inverter, or cooling systems are expensive if they fail out of warranty. Most hybrid battery coverage runs 8 years/100,000 miles or better, and failures in that window are uncommon, but a replacement outside warranty is a four-figure event, not a $200 one. Some hybrids also chew through tires a bit faster due to weight and instant torque. Net: think of hybrids as cheaper to maintain and slightly riskier to repair.
Driver-assist sensors are a different story, and this is where the scary talk has real substance. There's no scheduled maintenance on them — you don't service a radar unit. The cost shows up in specific situations: windshield replacement (cameras mounted behind the glass usually require recalibration), wheel alignments on cars with forward-facing cameras, and any collision or bumper work that disturbs a sensor. Industry figures put a single calibration around $300–$500, and AAA's 2023 repair-cost study found ADAS components and calibration accounted for roughly a quarter of a windshield replacement bill and about 40% of a minor rear-impact repair. Sensor replacement plus calibration can run into four figures.
So what does that mean for your wallet over the next few years? Realistically, budget a few hundred dollars extra across several years for calibration-type events rather than a big annual hit. The two things that will move the number most are whether your glass coverage includes recalibration (check your policy — many do, some cap it) and whether you're prone to windshield chips. Keeping a modest sinking fund of $50–$75 a month covers either scenario comfortably.
One caveat: I don't know your specific vehicle, and costs vary a lot by brand — a Toyota hybrid and a European plug-in hybrid with a camera-heavy windshield are very different financial animals. If you tell me the models you're considering, I can get more specific.
Finally: I'd treat "hybrids and sensors will wreck you on maintenance" as overstated, but "modern cars make certain repairs more expensive" as true and worth planning for.
