  1. Practically, all engines with thiis VCM are going to fail in matters of when, not if. That's why Honda now is moving to Hybrid just like Toyota. To get a better mpg hybrid is the best solution. 3 cylinders small turbo engines are not acceptable for NAmerica, they failed way too early with the way people in US/Canada use and maintain their car.

  2.  @karlschauff7989  statistics tells VCM is cursed by design, just like direct injection only, or hybrid eith belt type CVT in older Honda. VVT-i and vtec has no problem by design. Tbey are proven reliable. We talk about majority of VCM not 1 or 2 cases that has no problems and majority of 0 issues in vvti not 1 or 2 lemons.

  3.  @azzajohnson2123  Yes, Honda and GM are just too stubborn keeping VCM technology that cannot be improved by prohibited physics thermodynamics for reliability. Going to full hybrid is proven to be way more reliable with AISIN type HSD in Toyota and Ford. You can gain 2x mpg with hybrid in city drive and the same reliability on the power train. Yes, the battery may need replacement in 10-17 years (depends on climate) but it still cost way less than the fuel-saving over 5 years.

  4. @Ellis Murdough try to sell it? Just don't buy any car with VCM. does not matter from Honda, Mazda, GM, Chrysler, etc. They are all bad by design. Just like all type of DCT transmission, it only matters of when they will fail.

  5.  @azzajohnson2123  No, CVT are great, efficient, and reliable when it is made well like most Toyota and newer Honda. Yes, it has the subjective feeling of rubbery but it actually gives the most torque and power per engine RPM. Many Prius, RX, ES, Camry, Corolla hybrid with e-CVT are still running well beyond 400k miles. It is all gears, no clutch, no belt, no torque converter. Just full planetary gears and power splitter, like differential box (extremely simple). The belt CVT in Corolla/Auris and Avensis are also reliable. CVT has a bad reputation because of JATCO-Nissan crappy built, just like dual-clutch by VW, Ford, and early KIA/Hyundai. CVT in 2.0L corolla has real 1st gear and launch really well, you also can turn the simulated gear shift on it. Really nice drive and we know it is most likely as reliable as older corolla CVT. You just need to change the fluid regularly with proper level
