I just had my 2001 Vision into the shop because the power would completely shut off and kill the truck. It started once about a year and a half ago, then built up to once a month and progressed to yesterday's 25 to 30 times in 4 hours. It would go about 200 or so yards and just kill. After getting it into the Mack Shop they found there was antifreeze in the ECU. Somehow it came in through the wiring harness, the temperature sending unit was leaking. $3,000.00, a new ECU and wiring harness later, I and the guys at the shop are wondering "WHY?" and "HOW?" Has anyone else ever had any similar problems? I would be very interested to know how this would happen.
