The pressure plate comes apart due to clutch slip/overheating aka not normal wear and tear. Air in the system is the cause for clutch slip plain and simple. These systems are very hard to bleed all the air from the systemI’m now convinced that the way these are failing we are going to be seeing many more of these type of events. This looks like heat related metal failure of the flywheel. Even under normal conditions clutch friction generates heat. Given enough of these heat cycles metal is going to fatigue and even crack. A properly designed part will be designed to not self destruct when this fatigue occurs. (I haven’t seen a flywheel or pressure plate yet that hasn’t shown signs of the effect of heat). It could be a manufacturing defect but given the numbers we’re seeing and the range of manufacturing years in which these failures are occurring it’s looking more like a design failure than a manufacturing failure.
No part of the clutch, be it the flywheel, pressure plate or friction disc should be self destructing due to heat stress. Especially not on a “Trail Rated” vehicle like a Jeep. If anything this clutch should be designed to take even more abuse than most other vehicles.
