I am Selling a 2012 Dodge Durango V6 3.6 Engine SUV The Color is Grey . It Seats 7 . It has a New Engine that was put in on 8/09/2022 with 60,000 miles on the Engine . I have the Paper work for the New Engine . The odometer says 174,000 miles but it is not Accurate because they , the repair Company could not reset it to the right mileage . I spent $4400 on the Engine and $2,700 on Labor to put it in . A total of $7480 with Tax . The registration has been paid up to date but it will not pass Smog because it has a Check engine light for Catalyst System Efficiency Below Threshold Bank 2 . I just spent $1060 for a brand new Catalytic Converter the upstream and downstream O2 sensors before and after that Catalytic Converter and the check engine light went off for a while then came back on with the same code . I got that job done At a muffler shop and have the repair order for it . I Also have the Pink Slip/The Title .
