What happens if one of my characters that’s a Car while in alt mode but not in bot mode is KO’d
while it’s in bot mode?
[Source: WotC] 
Characters are put in the KO area in the same mode they were in on the battlefield. In that case, the
KO’d character isn’t a Car and won’t add to Cliffjumper’s bonus.
If I flip
Sunstreaker in KO area to alt mode to draw a card, would that still trigger Cliffjumper’s alt mode skill to draw a card?
[Source: WotC]
No. Abilities only look at things on the battlefield unless specifically stated.
Say I have Autobot Hot Rod (Sentinel) in the KO area and Cliffjumper in play in alt mode. When I flip Hot Rod in the KO area to bot mode, does it trigger Cliffjumper’s ability to draw a card? Since Cliffjumper’s ability doesn’t stipulate the Car has to be in play, it would seem like this would be valid, right?

No. Card abilities do not affect and are not affected by cards in the KO area unless specifically stated on the card.
Does transforming a Car-mode character in the
KO pile activate Cliffjumper's alternate mode ability?
[Source: WotC]
Not unless specifically stated. K.O.’d characters flipping wont trigger any abilities unless otherwise stated.
