There are definitely some threads at Pentax Forums devoted to this issue
and even instructions how to replace the solenoid yourself.
How to detect this issue:

The survey at Pentax Fora included the K-70 and no one reported a
failure. So you're probably safe with a K-70.

Thanks all for your comments. I hadn't come across the Pentax
Aperture Block problem, but I've now looked and it seems there are
few reports of it with the K-70, but less so than with other Pentax
models. I think I'll take the risk as I like some of the features, in
particular the fully articulated screen, which I find useful on my
Lumix bridge camera. It would be very disappointing if Pentax is
still putting out cameras with a known dodgy solenoid.
I'll keep you updated if it appears - I won't be happy.....

Welcome back. I was here 10 years ago but don't recall your name -
but memory
isn't a strong point at my age :-)
Before deciding on a K-70 it might be worth Googling "Pentax
Aperture Block"
which affected several cameras including, I think, the K-70. It
might be worth
considering a KP or even a lightly used K-5 II or K-5 IIs.
Cheers

I've just re-joined PDML after about 10 years - not that my absence
would have been noticeable as I was mainly a lurker. Work became too
busy and the bridge camera was more portable than the K20D when weight
was an issue. However the Lumix's focussing is too slow for a fast
moving 2 year old grandson, and it's been good to use the Pentax
more. I
might even be tempted to put batteries and film in the LX... And
should
I upgrade the K20D, now that I am retired and supposedly have more
time?
A better low light sensor would be good and the K-70 will probably
suit,
but I must do more research.
I recognise many of the same names as 10 years ago, some of whom I met
at the 2005 London PDML at Borough Market and the London Eye. I'm
enjoying not just the Pentax discussions and photos, but of course the
eclectic OT discussions ranging from US domestic voltages to Covid-19
antibody responses. As a microbiologist with an interest in the
history
of disease, the horrors of the past year have held a morbid
fascination,
but hopefully we will all be safely allowed out soon.
BTW, is there still a digest version?
back to lurking
