Every time the fire recall is used, or tested the elevator overshoots the 3rd floor the next time it is run up that high (which is only several times a day as that's the staff only floor)

Kone has been out both times and cant figure it out, runs it in test mode but will not test the fire recall to have us show them that thats what is causing the problem instead their sales manager continues to call us and tell us that the drive is shot and needs to be replaced at 5k. This elevator has only been in service for 1.5 years and the service man on site says that they are only made to last 1.5-2 years....

Also the code that I saw while he was here was just the safety showing that it over shot the floor and shut down, but now they are claiming that it was giving them an error code that meant the drive was bad.... anything we can do to check? or anyone had this problem before and know a solution, or get a hold of higher ups with kone to get this resolved?
