    Since this is a brand new model with lots of brand new tech and hardware, we early adopters are basically unpaid beta testers for Honda.
    This is why I justified $1,304 for an 8 yr warranty and I never buy extended warranties.

    I'm not familiar with the Insight CVT. What kind of CVT is it. It may be quite different than the clutch in the Clarity which really isn't a CVT at all but rather does do speed matching and only then engages the clutch. It's either connected to the wheels or not; no slipping or belts etc.

    I'm sorry to hear your Insight's CVT start-clutch didn't last the life of the car (many do). I never experienced that problem because my 2000 Insight and my current 2006 Insight both had the manual transmission/clutch, which never presented any problems for me. I wanted the manual transmission because it provides greater gas mileage than the CVT gen-1 Insight (even though the "lean-burn technology" that enables the increased gas mileage on manual Insights produces dirtier emissions).

    I must admit I don't have any technical documentation to back up my blind faith that the Clarity's computer-controlled Engine Drive clutch will prove to be reliable. My faith is based on advances in technology, the assumption a wet clutch is more reliable, and the relatively easy job the Clarity's Engine Drive clutch has to perform.

    The Insight's CVT start-clutch has to get the car rolling from a dead stop but the Clarity's Engine Drive clutch never has to perform such a stressful task. The operation of the Clarity's Engine Drive clutch is so smooth that I cannot detect its engagement when I'm driving--the only tip-off (other than the appearance of the gear icon), is that the engine speed becomes proportional to the road speed. That smooth operation makes me believe the i-MMD system is matching the engine's revs to the road speed before engaging the clutch.

    This may be true in the US but in Canada with the 10000km/6000miles/8 months oil charge/brake service, the local dealer charges $200+tax for it so it is actually more expensive than my old gas car doing 2 oil changes every year. This is also my first car that I bought extended warranty for the same reason you mentioned.
     
  6. A bit off topic, I know, but about Honda clutches...

    Our 2005 Element with MT has been the best/most reliable car we’ve ever owned.

    But the one major repair was clutch-related. Pulled up to a stop and could not get the car into any gear from neutral. Towed to a dealer. The problem was a small metal tab had fractured and fallen, jamming things up:

    You can see the tab missing on the top spring.

    Total bill was close to $1,500.

    Good news is since that repair, no other major issues and just turned 204,000 miles.

    The Clarity clutch might have issues down the road, but not due to wear.
    It isn't used for starting the car from a stop.
    It simply couples and decouples the generator and motor.
    If you can't feel the lock and unlock, then there are no torque forces applied.
    The drivetrain computer has matched revs for a seamless and transparent transition.
    Honda could have used the clutch to do this, but it would make the lockups noticeable and tedious to endure.
    Honda usually does a good job with QA.
    Keep in mind we have the last generation (GenII) Accord hybrid powertrain, not the newest (GenIII) - so there are more miles under this design.
    There are a lot of hybrid powertrain parts that could fail at some point with this level of complexity, but that's what an emissions warranty is for on these cars.
    15 years 150k miles in CA emissions states and 8 years 100K in Federal emissions states (there are a number of exceptions to Fed emissions)
