MY HUSBAND AND I PURCHASED A 2010 GMC ACADIA IN JULY 2012. SINCE WE'VE HAD THE VEHICLE WE HAVE ALREADY HAD TO REPLACE THE WATER PUMP WHICH FORTUNATELY IT WAS COVERED UNDER WARRANTY. BUT NOW THE AC IN THE VEHICLE HAS STOPPED WORKING. THE TECHNICIAN DID A BLACK LIGHT TESTING OF THE AC AND IT REVEALED LARGE AREAS OF ULTRA-VIOLET DYE COVERING THE AC HOSES AND SURROUNDING AREA. THEY RECHARGED A SMALL AMT OF R-134A FREON INTO THE SYSTEM TO HELP PINPOINT THE LEAK TO THE SUCTION AND DISCHARGE HOSES WHICH HAVE BLOWN. WHEN THEY CHECKED ON ORDERING THE HOSES, THESE HOSES ARE ON BACKORDER WHICH LEADS ME TO BELIEVE THEY HAVE BEEN HAVING NUMEROUS PROBLEMS WITH THESE HOSES. NOW WE'RE LOOKING AT BEING OUT $700 FOR A VEHICLE THAT IS ONLY 3 YRS OLD. *TR

WHEN PULLING OUT FROM A STOP, THE VEHICLE SHIFTS VERY HARD FROM 1ST TO 2ND GEAR. SOMETIMES THERE IS A LOUD CRUNCHING SOUND AND OCCASIONALLY IT WILL SHUDDER WHILE DRIVING. THE VEHICLE HESITATES ALL THE TIME WHEN TRYING TO ACCELERATE, AND WILL NOT DOWNSHIFT WHEN GOING UP HILLS. ERRATICALLY CHANGES GEARS EVEN WHILE TRAVELING AT THE SAME RATE OF SPEED, LIKE IT IS NOT SURE WHAT GEAR TO BE IN. THE CHECK-ENGINE LIGHT WILL COME ON AND IT WILL NOT CHANGE OUT OF 1ST GEAR, AND IT WILL STAY THIS WAY UNTIL THE VEHICLE IT TURNED OFF AND LEFT ALONE FOR A FEW MINUTES. THEN THE LIGHT WILL GO AWAY AFTER IT IS DRIVEN ABOUT 50 MILES. I HAVE HAD THE SHIFT SOLENOID REPLACED ($450 EXPENSE) WHICH IS THAT THE CODE SAID WAS WRONG, AND THIS DID NOT FIX THE PROBLEM OR HELP ANYTHING. *TR
