Transmission cooler line fittings have dissimilar metals causing the threads inside the radiator transcooler to strip and dump coolant into Transmission lines and on road along with what was the transmission fluid as well as steam rolling out blocking vision through my windshield going uphill on a dangerously busy road crossing.This is a well known manufacturing defect that has yet to be handled. This could have gotten me and my 3 year old son seriously hurt by sudden loss of power and slick roadways not being able to avoid or brake properly or even steer away from on coming collision. The dissimilar metals are aluminum nut with a mild steel washer backed by a stainless steel washer before it contacts the radiator. This car has 101k miles and has been babied it's entire life. And when I see the 4 brake lines are about to rust out after all the repairs that have already been done. This is just poor quality material and craftsmanship. Easily could have been avoided by simply using a different metal than mild steel between dissimilar metals.

First ECM module needing to be replaced, we replaced it then after that started running rough, took it to auto zone, 12 codes popped up. Did normal maintenance of vehicle, oil change spark plugs . Then a few days later we were on the highway and all of a sudden we lost all power, pushed on accelerator no power, front end started shaking, so pulled over, vehicle was very hot and smells like gas, had it towed compression test were no good, was told gasket were bad, also was told to check the recall list. Im up set because our children were in the vehicle with us. I hope we are able to get whatever needs to be fixed on this vehicle. Thank you.

There's a very hard jerking coming from some where in the rear area while driving. When this happens there is a lost of power. Also the engine oil is going some where ,I keep having to put oil in it , about two to three quarts a week. When the oil gets real low the engine shakes and runs like crap and acts like it wants to cut off.
