Christians say the New Testament, like the Old Testament, is entirely reliable, although some acknowledge minor errors that they say do not affect the theology of the Bible.
The Gospels of Matthew, Mark and Luke are called synoptic gospels, because they are reasonably consistent in their content, but even they differ on important points.
Raymond E. Brown (An Introduction to the New Testament)says that, although Luke likes to set his Christian drama in the context of well-known events from antiquity, sometimes he does so inaccurately.
Origen (Commentary on John), in defending John's Gospel, which differs significantly from the other three, said "although he does not always tell the truth literally, he always tells it spiritually".
Acts of the Apostles is considered famous for its discrepancies with Paul's epistles and for its historical inaccuracies.
The second century Roman teacher, Gaius, called Revelation "heretical".
Note that, in early Christianity, the form of the New Testament was not fixed. This is because it is a collection of writings from various sources. At a big conference in, I think, the third century it was decided which writings would be kept in and which excluded, and there was a quasi-political motive in some of the exclusions. So it's up to you to judge whether the whole collection can be considered reliable.
