This has been covered here before the current line of 3.6s do not suffer timing chain issues. There are a few different variations of the engine. Cline has covered it in depth before. You would be concerned with LLT They had most of the timing chain failures. The LFX, LF3, LF4, LFY, LGX and LGZ do not suffer the issue like the LLT. The LLT was used from 08 To 2017. The LFX was phased out in 2020. You have to figure out engine code and build date as some time around 2012 components were updated, but the stigma last due to bad information.
Having said that I think a mini van would be best. The are way cheaper and the ones I have driven were not really all that bad.
