I went to the same place you went.

My 16 month old 2008 Accord Sedan EXL V6 simply turned off while going 35 mph.
Would crank but not start. Towed to dealership and checked out. Timing belt "shredded". The cause was not exactly determined, but a series of failures led to the timing belt and, of course, to the valves being destroyed. A repair is underway.
Anyone hear of such a potentially dangerous (good thing we had pulled off of I-95) mechanical failure on a car with less than 34,000 miles?
By the way -- no warning lights, no sounds out of the ordinary. In fact, it was running like a top, as usual, until it stopped.

I will be very interested to hear their diagnosis of why this happened--the belt on the Accord is supposed to be good for 100k miles before replacement, isn't it?
Is the tension on the belt maintained by oil pressure? If so, and if you haven't kept records of oil changes, then the dealership and/or the manufacturer may claim neglect, and decline to cover the cost of your repairs.
One more thought--could malfunctioning VCM have triggered this failure?

This is a serious flaw....... A slight misalignment of all pullies/sprockets that the timing belt goes around ( just like A/C, Alt., P/S belts) could cause fast wear of timing belt. A frozen timing belt tensioner (just like frozen outer belt tensioner) could cause destruction of timing belt.
A timing belt made out of some flawed process/material could also fall apart on its own under normal use.
Oil pressure, driving fast/slow has no effect on timing belt. Too hot or too cold climate could make the belt go sooner than its 105K mile service interval but not at 34K miles.
Just make sure this repair is well documented. If it happens again, it is clearly a case of an engine put together not quite right. Make sure service manager puts down on your service order as when the next timin belt change is due and stick to it.

Could you enlighten me on timing belts/chains? Does the I4 have one? If so, does it also have to be replaced at 105K?

The I4 has a chain, not a belt, and it is intended to last the life of the engine.

Hopefully, it was something as simple as a bolt not being torqued enough, and the problem will not happen again. Let us know what they determine as the cause.

The dealership service department was directed by Honda to repair the damage....
the service dept has reservations about whether they can fully restore the motor to its proper compression. This afternoon we'll find out.
I'll try to get a straight answer about the sequence of failures and pass it on. Thanks.
