Stove replacement help

[Bryce Hammill]

I was looking for some guidance on a stove replacement.  This is in our first out of state duplex. We replaced a stove in one unit as it quit working. (Inspection photos from purchase shows the stove was 5 years old.) This was in December of 22. Now the PM company is saying the tenants stove turns off half way during use. I feel like replacing the stove after 6 months is a little unreasonable. What do you think would be the best way to resolve this problem? Send a repairman to check it out? Just feel like tenant is taking advantage of us recently.
