NHTSA Complaint #10279378 — 2005 SATURN ION

I BOUGHT A 2005 SATURN ION IN MARCH 2008. SINCE THEN, I HAVE HAD THE KEY GET STUCK ON A CONSTANT BASIS. I HAD THAT FIXED, BUT THE KEY STILL STICKS, BUT I PUSH IT IN TO RELEASE IT. AT LEAST IT'S BETTER THAN IT WAS. THE CAR DOES NOT LIKE TO START IN COLD WEATHER. I REPLACED THE BATTERY. COST $421.00. NOW, AT ONLY 45,888 MILES, MY STEERING DISPLAY LIGHT KEEPS COMING ON AND I LOSE POWER STEERING. GOT IS CHECKED TOLD COST $700 TOTAL, BUT THE ONLY PROBLEM IS: NO PART IS AVAILABLE. IT IS ON BACK LOG. SO, I CAN'T AFFORD THE PART AND LABOR ANYWAY, BUT NO PART AVAILABLE? WHAT DO I DO NOW WITH A CAR I AM STILL PAYING ON? I FEEL I A M STUCK WITH A LEMON. *TR
