2021 Dodge Durango Transmission Problems

Your engine cooling system may fail due to ruptured coolant lines, including tubes that supply coolant to the rear air conditioning system and transmission heater hoses. This causes coolant to leak out, leading to engine overheating during normal driving, which can create a sudden loss of power and risk of collision in traffic. The ruptures appear to result from how the lines are routed near the transmission, causing wear over time. Repair typically involves replacing the damaged coolant lines and hoses, with estimates around $3,600.

The heating hose exploded due to unknown pressure and ended up getting steaming, hot coolant, and all the cylinders and causing engine failure on a Dodge Durango that I purchased 80 days ago. and I have manufacturer, the dealer and an extended warranty, and after verbal and written promises, now I’m left with almost a $20,000 bill and no car and wasting money on rentals. I have filed to BBB and other complaints towards the dealership. I have tons of other people who have had similar problems with this year and model and newer.
