NHTSA Complaint #11540828 — 2019 DODGE DURANGO

The vent tube leading to the transmission came disconnected and sucked up water into my transmission. Leading to the transmission to not have any power. My son and I were in the the car trying to go up the hill when it lost power and started rolling backwards down the hill into traffic with the gas pedal to the floor. The mechanic at dodge said he has no idea how the vent tube was able to suck up that much water into the transmission. There was no lights that came on about the vent tube until it was too late and even then the check engine light would go on and off every time the car was turned off. The car is un drivable and currently at JT Dodge land in Columbia SC. I have notified my Insurance to see if this is something that would be covered l.
