Yesterday, I had a Subaru and a Honda, both around 10 years old, show up with melted cats, barely able to drag themselves beyond walking speed.  I bet it's been a decade since the last time I saw a melted cat.  Lots of catalyst efficiency code, but none melted.  Is the moon in Leo, or something?

I used to hear this a lot from customers (auto repair shops).  Things seemed to go in odd waves.  Coincidence?  Probably.  But another coincidence is that I heard it a lot, lol.

I've noticed that weird stuff seems to come in pairs.

Went years without seeing a Pontiac Torrent.  Saw two in a month, both needed wheel bearings.  One started disintegrating when I tried removing a bearing and ended up going to the scrapper, the other merely bent a strut.  And popped the axle free from the CV joint, which I discovered about two seconds into the road test.

 

Two Subaru EJ255s with bad engines in a row, in the same month.  These engines are rare here in not-mountainous country, but still, I had never seen a failure before.  One lost a thrust bearing, the other lost an exhaust valve.

Both were in Bajas.  The only two Bajas I'd ever worked on.  I never saw any even when they were new...

I paid a shop to install a new clutch two years ago(wasn't doing it in my snowy/steep driveway) and they handed me big chunks of my melted cat. Big ole chunks. That poor cat is still going though, I guess.

I spent 14-years in office equipment repair & it was definitely true. 

The other thing was after you'd spent a year or two working on a certain brand/model & had learned its common failure modes, you'd get a call regarding the same symptom - but it would be a completely different cause, which you'd then start seeing with regularity.

I sell parts for stamping presses. Certain lube pumps went obsolete and I have to come up with suitable lube units to replace them. I will go months without doing one, then have ten in a week.

When I worked on cars it was the same way with gm fuel pumps.

I just work the parts counter at Napa, we seem to have waves of similar cars needing similar repairs at times as well. Like 5 Impala's spanning a 3 year variance all needing power-steering hoses so then we add extra to the inventory to have it, to suddenly sell maybe 1 in the following year. It's weird.
