I ready go pick up my jeep gc 4.0l 4x4. I ride 9 hours bus to go meet up with the dealer that I bought the car from. He went pick me up at greyhound station with the jeep. It run good . After everything done. He ask me if I want power train warranty for 100 dollar more. I say 50 and he agree give me 3 month or 4k mile power train warranty. Got all payper work done. Went to walmart pick up 2 bottle of techron . Fill the jeep up and ready for 400 miles home. At soon I get in 70 mph the car vibration . I call the dealer and he say it properly need aligment or bad tires. I told him Monday I get those done after I get back . 200 miles later I make a jerking. I heard loud noise and smell smoke. I stop the car right away and look under thr transfer case and front diff is dripping heavy oil. I call the dealer and he say get it to the newest mechanic and let him look at it and he pay for repair. I could not drive so I call 911 they brought the tow truck over and the tow guy say that the car been in 4 wheel drive whole time I was driving. I never touch the shifter and the shifter alway at 2wd position whole time. He agree to fix everything and now I'm just pay the tow guy 172 dollar and 50 dollar for hotel. He say he call me tomorrow. Now I'm 200+ miles away from home and in hotel can't sleep ATM. I hope they fix the problem. Cause thr townl guy say it properly need transfer case and front and rear diff. I don't know wat to do now. Ether go back stay with my friend and wait til they done repair or go home and come back when they done repair.
