The Autobots could easily be betrayed by:
*Patrick Dempseys' character, who seems to start off as a friend or colleague of either Sam or Carly, but apparently tries to kill Sam at the end, (and appears to be driving around in a Car that looks a lot like SideWays, who was a courier, and therefore could easily have been a message-arranger with Dempseys character in the unseen backstory of TF1 and the time gap from TF1 to the opening sequences of RoTf).
*Wheelie, who is prone to be terrorized back into Decepticon submission (tho I secretly suspect he may die in the same rumored 'failed assissination attempt on Sam' which allegedly kills Mikaela instead: in fact I ASSUME Wheelie will become Mikaelas 'bonded pal' as Bumblebee is to Sam).
*The Stunticons/Wreckers, who could easily start off as one group and then become the other (and actually continue to switch back and forth between factions several times over).
*Sams friend, Leo, who MAY become resentful of Sams centrality to the robot war after Leo prided himself on the internet site he ran in University and want a bigger take on events, thereby opening possibilities for 'bargaining' with Megzy or Shockwave.
*Shockwave, whom the Autobots don't necessarily need to have heard of before they meet him in this reality (he may actually betray the Autobots and Deceps both, tho I wouldn't anticipate him as a herald of Unicron in motive, I'd defenitely see how the Dictator of Cybertron would have his own secret police out to finish off any upstarts, be they Megz, Opty and/or the fallen, with Shockwave himself tackling the heavier objective).
*The not-Jolt-may-be-Wheeljack-blue-car-fiber-optic-Einstein-hair-robot "Q" (or "Cue") has been given a generic Mad Scientist vibe by some discussions which could make him a crazy Autobot newcomer with closet Decepticon 'values' in the long run.
*The Humans themselves, who are already on a 'Robots:Go Home' campaign which implies to be growing in popularity.
*The big red firetruck: I've heard this may be another Prime (Sentinel, I think it was said). He wouldn't betray the Autobots by action, but by news: He could easily arrive with a 'dark secret' or 'dark revelation' that either dashes Autobot hopes altogether or plays out as a catch-22 situation where they're damned if they do and they're damned if they don't do something or other.
*The blue vintage car (assuming it's a Bot) that arrives with the 'important looking SUVs at the Chicago fight:
Remembering that 'Bee (at least we assume it's 'Bee) takes on a vintage mode at some point, and for a while, (and that 'Bee is effectively an undercover agent), it's possible another TF is causing trouble during the Cold War period that 'Bee is moved by Optimus to intercept and deal with.
There was time travel talk surrounding this news about the vintage 'Bee mode, too, and a time bridge could be provided by the Firetruck-bot, but ultimately, the vintage blue car (assuming it's a Bot) arrives at the Chicago fight in present day in its' antiquated Altmode, so if there is a time travel mission, it may be a failed one.
(My best guess is that there's a whole mini community of (active, not dormant like Jetfire) old Altmode Tfs hiding out somewhere remote since the Cold War, and Megz finds them first).
The Autobot Matrix: Figuratively speaking, it can be construed as having 'betrayed' Ultra Magnus on Junkion, and actually 'all Autobots in their darkest hour' as a consequence of that moment.
(Some fans or speculators could go so far as to say that 'whiney' and 'insecure' Rodimus Prime as the 'choice' of the Matrix was yet another betrayal as many have made points that he is/was/will be an unfit leader).
(Off topic: My personal counterargument here is that HotRod simply set the Matrix to him, and it wasn't reset properly before Ultra Magnus tried to interface with it,but still waiting for HotRod to 'click Yes' whilst Rodimus Prime was an appropriate crisis leader and migration chieftain whilst Optimus was perfect as the embodiment of the disappearing Cybertronian and Autobot way).
But of course all of this is just speculation.
If I had to gamble for an Autobot faction turncoat I would guess Dempseys' Character, the Matrix (or an AllSpark shard or other artefact) together with the Firetruck or "Q/cue" in that order.
