Not many I suspect, it's why most of us, including me are cultural/nominal Muslims. Personally there are some stuff in the Qur'an which is troubling for sure, such as the verse allowing sex slaves, the beating of wives by their husbands and semen coming from the backbone and the ribs, etc.
I guess the greatest accomplishment of the Quran is its abstractness (Mountains as pegs, holding up the sky without pillars, sun setting in a murky pool etc etc). For example. Surah Lahab where all 5 verses are just cursing the uncle of prophet Muhammad PBUH. Without any context/tafsir or ahadith, if you simply read the quran alone you wouldn't know what's going on.
A lot of it also non-linear which makes it hard to follow.
My issues with the Quran is wrt to its preservation and compilation and whether that was done accordingly by Abu Bakr.
The second issue I have is with the transmission and propagation of ahadiths that came yeaaaars after the prophet died. There's no way in verifying whether the integrity of ahadiths were preserved since after all, the means of propagation were fallible humans. It's akin to playing the broken telephone in primary school were the end result is completely way off from what was initially intended. In that sense, it's quite possible that the Islam being followed today is way off from what prophet Muhammad practiced.
Now personally, I believe religion is more than anything a personal connection and simply what
feels right to a person. Do I know 100% that prophet Muhammad was divinely inspired? Nope. Do I care? Not really. Do I know 100% that Allah exists? Nope. Do I care? Not really. I guess you could call me an agnostic Muslim, if that's even a term
