Incompetence ... local Honda mechanics apparently are not trained to repair the CVT, they are simply told to replace the CVT whenever they encounter problems with it. I am not a mechanic, but a CVT is supposedly a simpler mechanical device than a conventional A/T because it has lesser mechanical parts. If only a smart mechanic is given the chance to rip apart the CVT, it would be easy for him to figure out how it works and repair it at minimal cost. But ... err ... if the mechanic is that smart, he'd probablty be appointed service manager in no time.
For the rollback on an incline, some cars do and some don't, and depend on the grade of the incline (which could explain the difference even on the same car model).
A P300k quote is more of greed than real service quality concern. We got rid of our 2 honda cars and it will be a long time before we acquire a honda again. I'm still a honda fan but the local dealership totally sucks! I'd rather setlle with a Hyundai, sounds like Honda anyway, but way more economical.
