why do the lifters have to be replaced again after the dealership just replaced 4 less than a year ago

What is your question?

MY daughter bought a Dodge Grand Caravan in November of 2022. After she drove it off the lot she had to return it in a few days because of the ticking noise it was making under the hood. The dealership said it was the lifters and they replaced them. Now its doing the same thing and they are replacing lifters. found out they only replace four of them. Don't know what it is going to cost. This is disgusting. Weren't they supposed to replace all 24 of them? Haven't had this vehicle for a year yet and my daughter has this big problem and probably a big expense. She had an old clunker Grand Caravan that never had this problem but everything else was going bad and it was all rusted out. Any help or suggestions with this big headache?

What makes this problem better or worse?
