Intake manifold leak at 65,470 miles. Leak at manifold near back of engine at throttle body. Caused engine to leak oil and coolant which can cause fire or engine to blow. Dealer repaired and replaced intake manifold and pcs valve.
We had an exhaust leak, and we didn't think that it was a big deal maybe a broken seal. I noticed the leak when I used my remote start in the morning. Turns out the exhaust manifold warped and broke bolts! this could have caused some serious safety issue if it hadn't been looked into. I looked at other Dodge Durango owner sites and this seems to be a common problem amongst owners of this make and model.
Our Dodge Durango 2012 was purchased in January 2015 from rick keefer Dodge Chrysler Jeep ram in yulee, florida. Two weeks later the engine light lights up and the engine is sputtering. Returned the car to dealer whom repaired vehicle and said it was the oxygen sensor and replaced. Again the engine light came on and the engine ran rough. Returned the car to dealer whom repaired and said they replaced the converter. Soon again the engine light came on. Found fuel cap 'popped off' a few times, engine light goes out then on again. Returned to dealer whom replaced fuel cap. There was also an oil leak fixed. Again the engine light came on and off and the engine would run rough. Smoke would pour out the tailpipe, engine sputtering, drove back from mountains. Returned car to dealer. They replaced powertrain control module and oxygen sensor (again). And again, late June 2015, engine light comes on and engine sputtering. Dealer takes car. Dealer tells us they are going to 'go through it' and drive vehicle entire time. We receive rental car. Dealer calls after week and said vehicle is ready for pickup but they are awaiting a converter and are going to replace oxygen sensor also. Vehicle mileage logged; vehicle was never 'driven'. Rental car time was used up. Returned car to dealer when part was in. Dealer replaced converter but not O2 sensor?? they said it didn't need it. Drove car about 10 miles and got out. A very strong smell of burning plastic is coming from car. Dealer not returning call. Will be returning to dealer Monday july20, 2015. Still driving with strong plastic burn smell. Lifted hood. Wiring harness above heater line and converter(manifold) is burning. Entire right side of engine is unbearable hot. Silver metal box in front of fuse panel is so hot it burns to the touch. Car reads normal temps? most problems on blog occur in hot summer months. Coincidence?.
