2007 DODGE NITRO 4X2 Unknown Or Other Problems

I HAVE OWNED THE CAR SINCE 2012 AND HAVE NO MAJOR ISSUES UNTIL NOW. MY REAR B.C. ACK PASSENGERS WINDOW MALFUNCTIONED OUT OF NOWHERE AND I TREAT MY TRUCK WITH THE MOST CAR. I MAINTAIN IT, SERVICE IT, GARAGE KEPT, AND IT ONLY HAS 90000 MILES AS OF LAST YEAR WHEN I WAS FORCED TO DRIVE IT.

I CURRENTLY HAVE AROUND 165K MILES ON THE TRUCK. THE CHECK ENGINE LIGHT STAYS ON, NOW THEY HAVE TO DO THE SMOKE TEST AND I'M AFRAID OF THE OUTCOME/COSTS. :( I ALSO HAVE SMALLER BROKEN THINGS, THE GLOVE BOX HINGE BROKE, THE TIRE SENSOR HAS HAD TO BE REPLACED AT LEAST 3 TIMES SINCE I HAD THE TRUCK. ALSO, THERE'S A CLICKING SOUND IN THE STEERING COLUMN. ALONG WITH THE LIGHTING IS OUT WHERE THE DRIVE/REVERSE/ETC INDICATOR IS (IT'S WHERE I SHIFT). I'M 55 YEARS OLD AND NOT HARD ON THE CAR, CONSTANT OIL CHANGE/TUNEUP AND ALL MAINT THINGS ARE UP TO DATE. I CAN'T BELIEVE IT IS NOW FALLING APART. I'VE NEVER...
