About what?
People can be wrong without being liars so just because she is honest doesn't mean she will be right about everything.
When people repeat hearsay reliability is a big problem because A) the person speaking to them could be wrong and B) they can misinterpret what the person speaking to them is saying.
When recounting things another problem is memories fade plus people pick up information and mistakenly recall knowing about things sooner than they actually did. In one case years later an officer read in a book that the ballistic expert knew right away what the caliber of weapon was. he then claimed that he knew right away what caliber weapons was used. The ballistic expert though didn't actually tell anyone at the scene. He made sure he was right in the lab first. So the cop was wrong about being informed of the caliber right away and he was wrong because instead of going by his notes exclusively he went by what he read in a book though what he read was incomplete. The power of suggestion is strong that is why witness lineups are so regulated.
If someone's photo is previously seen by the witness that can cause them to pick out the person instead of them going by their memory from what they saw at the scene. In one case a witness saw a photo of the suspects care with the license plate visible and the witness then claimed they recalled the license plate they saw though in fact they told police nothing of the sort at the time this came later after they looked at photos. The same things happens in other respects than just looking at photos and picking up info from that and incorporating it into the memory.
You have to look at all the relevant evidence and circumstances to determine whether her claims are accurate or not.
