The next day, after Optimus used his navigation scanner on Archibald Witwicky's glasses, Jazz again commented that they could not leave Bumblebee to die at the hands of Sector Seven, to become a human experiment. After Bumblebee was captured by Sector Seven during the retreat, Jazz expressed his desire to rescue him but was overruled by Optimus Prime, who didn't believe it possible to accomplish this without harming the humans, and so they should let them go. When the agents attempted to resist, Jazz used a magnet to relieve the humans of their weapons. When Sam and Mikaela were captured by Sector Seven, the Autobots mounted a rescue that saw Optimus Prime tearing the roof off Agent Simmons's vehicle.

When it came to hiding from the parents, Jazz had the easiest time blending into the shadows due to his small stature. Soon after, as Sam looked for his grandfather's glasses, the Autobots attempted to assist by clumsily destroying the yard where they went. He then relayed their mission to find the AllSpark and explained how his grandfather's glasses were the key to its location. He casually sat on the hood of another car while Optimus Prime explained to Sam they learned Earth's languages through the World Wide Web. Linking up with his fellow Autobots in a deserted alley, Jazz greeted Sam and Mikaela Banes as 'little bitches,' stating that Earth seems to be a cool place to hang out. Jazz was part of Optimus Prime's unit, summoned to Earth by Bumblebee after the later Autobot came to be in the possession of Sam Witwicky. After his protoform crashed through a baseball stadium, he investigated a nearby car dealership and chose a Pontiac Solstice hardtop as his vehicle mode. Jazz was part of the team that discovered him in the wreckage after the Decepticons had left. Later after it was discovered that Megatron was building a massive starship for some unknown purpose, Jazz was the one who suggested they should have their own ship as well, just in case. As part of a crowd of Autobots, he later watched from a distance as the Decepticon ship was launched. During the subsequent civil war, Jazz fought alongside Optimus Prime in their struggle for freedom, but as the war reached its height, Optimus decided to launch the AllSpark into space to keep it out of Lord Megatron's hands and to buy them time. Bumblebee was successful in diverting the Decepticon leader's attention at Tyger Pax, but was grievously injured as a result. Jazz and several other former security officers helped Cliffjumper'capture' the former military officer Ironhide and bring him into the rebel base to see Optimus Prime. Optimus directed the others in a successful counterattack and ordered the group to rally at Burthov. However, on the way to Trypticon, the group were ambushed by members of the Defense Force sent to kill them. Later, Jazz was part of the team sent to arrest Optimus for treason. Jazz accompanied Optimus and Prowl to Megatron's quarters, where Optimus discovered that the relic previously unearthed seemed to have been restored by Megatron himself. Realising sentries such as Prowl and Jazz had access to Megatron's personal quarters, Prime asked them for a favour. Later, when Prime mentioned Megatron's questionable behavior and wished there was unity in the population, Jazz pointed out that he had the same chance of convincing Megatron to be unified as they do of being considered part of his army. When Megatron rallied Cybertron's inhabitants to war against the alien attackers, Jazz and most of the others in the science and security division loyally stayed at Optimus's side to uphold the ideals of Cybertron. Prowl theorised that the aliens were trying to break into the temple, not destroy it, Jazz opined that they must have been after the AllSpark.

In the aftermath, Jazz accompanied Prowl as the latter investigated the attack on the Simfur temple.

He was present when Arcee's team found a strange artifact with the strange symbol and helped escort the relic out of the dig site when the aliens whom Commander Starscream had encountered earlier suddenly attacked the planet. As Optimus pondered the venerable age of the artifacts they had found at an excavation near the temple of Simfur, Jazz jokingly asked if they were as old as Ratchet, earning him a threat of vocal processor-disabling retribution and a whack on the back of the head. Many years before the civil war on Cybertron, Jazz was a member of the Security Force under Prowl.
