The page's avatar was changed to the Cadillac symbol about 12:30 p.m., and tweets said the company had been sold to the rival car company.
A link from the profile went to http://www.jeep.com/press/sold-to-cadillac, a dead end on the official Jeep site.
Several of the tweets included shout-outs to jailed rapper Chief Keef, who was sentenced to 60 days in prison in January for violating his probation following a gun charge.
"We at @Jeep wanna share our motivation! :DDD," read one tweet that linked to a Chief Keef mixtape.
Another read, "<3 you @tania @meekmill @chiefkeef @lilreese300 F**K A TOOKA GANG BITCH IM #300."
The hack was similar to Burger King's Monday, during which the fast food company tweeted it had been sold to McDonald's. For a brief period Tuesday, the Jeep Twitter page background was a picture of a McDonald's car.
After being taken down entirely Monday, the Burger King account was back up Tuesday.
"Interesting day here at BURGER KING®, but we're back! Welcome to our new followers. Hope you all stick around!" the account tweeted.
Gizmodo reported the hacker is likely a New England DJ who goes by iThug.
