My van has been having problems all week. While driving down the road it started beeping, the power steering went out, a message came on the dash saying service electronic stability control, and the cruise control shut off.

I got the van home but it wouldn’t start anymore. The starter would engage and then it would shut off and all warning lights would turn on.

I heard from the dealer today that the issue was related to the installation of a tow package. The trailer brake was installed with the ground wire behind the TCM and the nut holding it in came loose. The system shorted and it fried the TCM.

The dealer said this is the second Pacifica they’ve had in this month with the exact same issue.
