I don't know of anyone that has had problems stemming from the microchip besides a spot of bleeding where it was inserted.
I do know of one microchip that migrated. It slipped from between the shoulder blades down to one of the sides of the dog, but was still easy to be found by a scanner.
I know of one microchip that failed (similar to what it sounds like happened to Ciara). The owner went to scan it and it didn't show up, and this was a young dog too. Unfortunately, he already had at least one health test registered under the old microchip, so now they are going to have to go through the hassle of changing the microchip number in a few places to the new one.
