  Welcome to the club. Was your wife using another Karoo 2 or different brand?

  I have elevation issues since I purchased Karoo 2 (2-3 months ago). It constantly shows higher elevation then other devices, e.g. Suunto 9 Peak Pro, Garmin, Strava. However, the high/low point is correct/same as by the other devices. The difference is significant, for example in todays ride (around 45km) it was 116m (by Karoo 2) vs 194m (by Suunto 9 PP).

  Could you check your ride in hammerhead dashboard and look at the temperature reading? I think ive found a correlation between rapid temperature changes and altitude reading being way off

  I have and had for long time the same problems at many rides. For example 700m instead of 200 m. It is my second Karoo2 with this issue.

  Same here, 60 meters will be shown as 300. Strava knows better, luckely

  I have the same problem.  On the West Coast of USA, a 2000 ft ride registered as 2700 ft.  The ride before, everyone else recorded 1800ft while I recorded 2800ft (all numbers rounded).  I tried entering a starting elevation manually but it didn't help.  
  
  In another thread I read that it helps to be sure that mobile data is turned off so false gps data is not imported from cell towers.
    I do really like the Karoo but it wd be nice to get this bug fixed.

  Ok, I have figured out what is causing the elevation issue....vibrations!

  Today I went out with 2 Karoos...one mounted on a stem on my rigid gravel bike and one in my back pocket.

  The ride is quite rough with quite a lot of road vibrations.

  The Karoo on my bike on a 75km ride reported 1280m total ascent...the one in my pocket recorded 820m ascent...my Apple watch recorded 765m ascent

  When I use the Karoo for running,  elevation is also spot on since it is in my backpack.

  When I use it on my MTB the elevation is a little  high but not as bad as on my rigid gravel bike.

  There is NO way that Hammerhead has not figured this out...and I cannot see how they can fix this since it is affecting a lot of people and is probably related to the barometer being affected by vibrations...perhaps a software fix could be to smooth out the sampling...I don't know but if that was the case a fix should already have been issued.

  Please try and do a ride with the Karoo in your back pocket and see if you get the same result...
