Clutch failure in one year 6 speed NV.
Factory clutch very poor quality.
Strong motor.
It must be the way you drive 180000 mile and still the original clutch.
I'd have to agree with the other guy, I have 225000 on my original clutch and pull a 12000 pound trailer daily with it.
Mine has 260000KM and clutch has never been replaced. I had to replace the tensioner in the transfer case. This is the only problem I've had to date.
Sounds like the original reviewer just can't drive a clutch, or keeps revving it up to move heavy loads and burns it out.
