(1) no known events leading up to first failure. Second failure, is due to an unexplained oil loss. No oil trails are viable from / on the engine, nor are there puddles present in the driveway. Last oil change was less the 10 days prior to the crank bearing failure. Oil level verified good by owner prior to leaving service station and at no time did the engine warning light come on. (2) "first failure", head damage due to misaligned valve and loss of compression on cylinder #3. Second failure, short-block damage due to oil loss and subsequent bearing damage. Failure confirmed off cylinder # 3, with stethoscope. (3) rebuilt the head unit at 6 months worth of my time, and at a cost of $3,500. Currently waiting have the short block replaced to correct its bearing failure, at an est. Cost of $8,000. All of this has been done with out assistance from Honda, despite my best efforts in repeatedly asking for their assistance / compensation. Honda and their dealers do their best to delay, ignore, refute all claims in the hopes that I'll just go away. I have read similar posts about engine failures for the sk2, all having a similar failure on cylinder # 3, and all getting the same response / treatment from Honda: "that the customer created this problem" or "despite the fact it's under warranty, it's your fault the engine failed, and hence we will not cover the cost of repairs" either Honda is unaware of what's going on with its dealers (which seriously I doubt), or it doesn't care. Regardless, its service dealers are running amok, making upwards of 3 to 8 thousand dollars a vehicle.
