2006 CHRYSLER SEBRING Engine And Engine Coolingcooling System Problems

I AM HAVING PROBLEMS WITH MY 2006 CHYRSLER SEBRING. IT STARTED IN 2008 OR 2009 WHEN CAR RAN HOT ON THE INTERSTATE. I ADDED COOLANT BUT IT SEEMS TO EVAPORATE OR LEAK. I WENT INTO LANDERS DODGE FOR AN OIL CHANGE AND UPON INSPECTING THE VEHICLE THEY FOUND A LEAKAGE FROM WHAT THEY SAY IS CALLED A COOLANT INLET TUBE WHICH WILL COST ME OVER $400 TO REPAIR. I FEEL THAT WITH MY CAR BEING ONLY 2 OR 3 YEARS OLD AT THE TIME SHOULD NOT BE TAKING PLACE. I HAVE ALSO FOUND OTHERS THAT HAVE THE SAME VEHICLE TO HAVE THE SAME PROBLEM OR HAVING TO REPLACE THE TRANSMISSION IN 2006 CHRYSLER SEBRINGS. I WOULD LIKE TO KNOW HOW THE SITUATION CAN BE LOOKED INTO.

THIS IS A 2006 SEBRING TOURING, BOUGHT WITH AROUND 33,00 MILES. THE FIRST NIGHT I TRIED THIS CAR, THE CHECK ENGINE LIGHT CAME ON WITH THEM SAYING THEY WOULD FIX IT. IT DIDN'T COME BACK ON FOR MONTHS...AFTER THE WARRANTY WAS UP. I HAVE HAD THIS CAR ALMOST A YEAR AND IT HAD A 30 DAY WARRANTY. I TOOK IT BACK AT LEAST ONCE A WEEK FOR THE WARRANTY WITH THEM SAYING THEY COULD FIND NOTHING WRONG. THE BRAKES MAKE RUBBING NOISES, EVEN THOUGH I WAS TOLD THEY PUT ON NEW BRAKE SHOES AND IT WOBBLES, EVEN THOUGH THEY SAID THEY CALIBRATED THE ROTORS AND FIXED THEM. IT JUMPS WHEN YOU STOP AND ON TAKE OFF IT JUST TOOK IT TO ANOTHER SHOP IN ANOTHER TOWN AND WAS TOLD THEY COULDN'T FIND ANY WRONG OTHER THAN IT NEEDED AN UPDATE AND THAT THIS SHOULD TAKE CARE OF 99% OF MY...
