1 Power Train problem

Failure Date: 12/12/2025

The engine cooling system on my 2021 Dodge Durango gt failed due to ruptured coolant lines, including the rear coolant tubes supplying the rear air conditioning system and both transmission heater hoses. These lines carry engine coolant to the rear hvac system and transmission. The ruptures caused coolant loss and engine overheating during normal operation. The failure appears related to the routing of the lines near the transmission housing, causing excessive wear not attributable to driver error. This model year has a documented history of similar failures. The vehicle and components are available for inspection and are currently at the dealership. My safety and the safety of others were put at risk because the vehicle overheated while I was driving at normal speed in traffic. A major overheating warning appeared while driving. Overheating in traffic creates a risk of sudden loss of power or the need to stop unexpectedly, which could result in a collision. Although I was able to drive slowly due to proximity to home, this condition would be hazardous on longer trips. The issue was confirmed by an authorized Dodge dealership, which verified failure of the coolant lines and provided an estimated repair cost of approximately $3,600. The vehicle has only been inspected by the dealership. A third-party warranty provider (warranty solutions) denied coverage, and I am disputing the decision. The vehicle remains at the dealership because I do not feel it is safe to drive. No prior warning signs were present. The overheating warning appeared suddenly at approximately 62,000 miles. I noticed the smell of coolant upon arrival at the dealership, indicating an active leak.

2 Power Train problem

Failure Date: 05/27/2025

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.
