Something must be wrong with the way they are installed. I used P-P's for
years in the mobile (a 4X4 that was off-road as much as on) and NEVER had
an inadvertent disconnect.

I've assembled hundreds of Power Pole connector sets -- they're on
everything in my station that runs on DC, and on all of the non-ham
gear powered by wall warts or other DC supplies. I've never seen a
Power Pole crimper -- all of mine are soldered.
I find them very easy to do, once you understand how they work. Inside
each plastic housing is a spring. The contacts have a sort of curled
lip that is intended to fit over that spring, which locks it in
position. The contact must be inserted so that the curl is in the
right direction, and it must be pushed all the way to the spring.
Usually you will hear a click when that happens.
For small diameter wire, I often must use a small screw driver (like
the miniature Xcelite Red or Green) to push the contact from the wire
side of the housing. For large diameter wire, it may be necessary to
strip a bit more insulation so that it fits into the housing.
The only times I find it difficult to install a Power Pole is when I'm
using #10 wire, which requires the largest of the three sizes of
contacts (the type with the U-shaped holder for the wire). The wire
must be very carefully tinned, inserted very carefully, and the
U-shaped holder carefully folded over so that it fits into the
housing. I do this with a pair of needlenose pliers. A crimper might
make that easier.
The only times I've had Power Poles disconnect were when the DC cable
for one of my K3s was too short, and I pulled the radio forward.
