Same issues as others as reported for tipm failures in vw Routan / Chrysler vehicles. The underlying common part is the the part number for the totally integrated power module in the 2012 Volkswagen Routan is vw 7b0937049. The part number in the Volkswagen Routan translates to Chrysler's part number 68105507 ac/ad. Although Chrysler has done a settlement in a class action lawsuit, the actual vehicles recalled are limited and about 1mm of the 7mm affected vehicles with faulty tipms.
