Some of the worst effects aren't immediately obvious, such as metastatic calcification of tissues over time.
Long-term effects aren't fully elucidated because high Vitamin D doses weren't common until recently. However, there is growing evidence that excess Vitamin D can contribute to worsening cardiovascular disease and premature aging of cells.
You won't necessarily feel the effects of too-high Vitamin D levels right away, but years or decades of excess Vitamin D could do a lot of hidden damage without any benefit over moderate levels.

Can you please avoid making statements like this without adding a link to a peer-reviewed paper so that we can assess it.

As to excessive dose: " Without calcium supplementation, even very high vitamin D3 supplementation does not cause vascular calcification, especially if another important finding is included. Even when calcium blood levels are high, the culprit for undesirable vascular calcification is not vitamin D but insufficient blood levels of vitamin K2".
