Bosch CX performance gen 4 dead

[1oldfart]

i think bosch is still the leader in reliability but most of the top motors are pretty good.
the new Shimano rattle sound seems pretty insignificant compared to an all out motor failure and brose seems to have the preponderance of those .
I have a Bosch cx gen 3 that i ve had for about five years . i had a software problem that occurred in the first few weeks . they did a five minute update and i have had zero problems since .
The motor im really looking forward to testing is the Sachs out of germany .

Please share your experience and info about Sachs.
