Karoo 2 elevation error complaints
A quick google search shows lots of forum posts on various sites about Karoo 2 elevation errors.

This post shows their elevation chart, with repeated short, sharp elevation spikes in the middle of normal road grades. More often on downhills, but also on flats and climbs. The summary says "max grade 55%" !!
