2017 GMC SIERRA 1500 Engine Problems

MY RADIATOR HAS DEVELOPED A LEAK AND COOLANT IS ESCAPING WHEN ENGINE IS HOT. THE ISSUE APPEARS TO BE VERY SIMILAR TO THE INCIDENTS WITH THE 2014-15 MODEL YEAR ISSUE. THE PROBLEM WAS DIAGNOSED TO BE A LEAKING RADIATOR NEAR THE TOP RIGHT SIDE BY AN INDEPENDENT MECHANIC. *TR

THE VEHICLE WAS PURCHASED IN JANUARY 2017, SINCE THE PURCHASE OF THE VEHICLE, I HAVE HAD THE TRUCK IN THE SHOP ON 6 OCCASIONS. THE VEHICLE HAS HAD 5 INJECTORS REPLACED AND THE UPPER OIL PAN GASKET HAS BEEN REPLACED TWICE. GMC IS STALLING ME AND NOT WANTING TO PURCHASE THE VEHICLE BACK UNDER THE BUY BACK PROGRAM COMMONLY CALLED THE LEMON LAW. THE VEHICLE HAS AN EXTENDED WARRANTY AND I HAVE BEEN CHARGED A CO-PAY WITH THE REPAIRS ON THE VEHICLE. THE ISSUES STARTED AFTER THE 30000 MILE SERVICE.

1. THE TRANSMISSION SHIFTS EXTREMELY ROUGH FROM 1ST TO 2ND GEAR IN PARKING LOTS AT A SLOW SPEED AND ON NORMAL HIGHWAY OR STREET DRIVING AND EXPERIENCES THE SAME THING WHILE SLOWING DOWN TO STOP 2. THE ENGINE HAS RECENTLY BEEN HAVING A AWKWARD SHAKE TO IT WHILE IN IDEAL AFTER IT HAS BEEN RUNNING AND WARM 3. WHILE BACKING UP AND TURNING THE WHEEL, THE FRONT SUSPENSION WILL LET OUT A LOUD CLUNK SOUND AND THE SOUND WILL RETURN WHEN TURNING THE WHEELS BACK FORWARD AFTER PUTTING IT INTO DRIVE.

THE VEHICLE WHICH HAS UNDER SEVEN HUNDRED MILES ON IT DOES THE FOLLOWING: WHEN I TRY TO ACCELERATE THE VEHICLE STARTS TO MISFIRE, STARTS TO CHUG AND JERK, IT STARTS TO HESITATE AND BECOMES ROUGH. WHEN I CALLED GMC SERVICE DEPARTMENT I WAS TOLD THERE WAS A CODE FOR THIS PROBLEM #PIP5457B BUT THAT CURRENTLY THERE IS NO KNOWN REASON AND NO KNOWN REPAIR AND NO KNOWN COMPUTER CODE TO REPAIR THE PROBLEM. I TRIED TO MERGE ONTO THE INTERSTATE HIGHWAY AND NEEDED TO SPEED UP BUT THE TRUCK STARTED TO LURCH; I NEARLY GOT REAR ENDED. I CAN'T DRIVE UP A HILL IN THE CITY OR ON THE INTERSTATE AND KEEP UP WITH THE FLOW OF TRAFFIC BECAUSE THE TRANSMISSION STARTS TO SPUTTER. MY WIFE AND I ARE AFRAID TO DRIVE THIS VEHICLE. WE JUST PAID NEARLY $49,000 FOR THIS GMC SIERRA 2017 AND ONLY OWNED IT FOR ONE...
