2014 GMC SIERRA Complaints

I HAD MY TRUCK'S ECM REPROGRAMMED LAST FRIDAY (1/17) DUE TO RECALL #14V007, AND EARLIER THIS EVENING (1/24) THE CHECK ENGINE LIGHT CAME IN AND THE DIC SHOWED AN "ENGINE POWER IS REDUCED" MESSAGE. THE ENGINE RAN VERY SLUGGISH AND I PARKED IT AS GM RECOMMENDED TO DO IN THEIR RECALL LETTER. THIS IS THE SECOND TIME THIS HAS HAPPENED NOW. I THOUGHT THAT THE NEW SOFTWARE WAS SUPPOSED TO CORRECT THAT ISSUE? *TR

2014 GMC SIERRA 1500 ROLLS BACKWARDS WHEN PARKED ON AN INCLINE AND THE TRANSMISSION IS IN PARK. *TR

I HAVE A 2014 GMC SIERRA 1500 CREW CAB. THE VEHICLE HAS A VIBRATION ABOVE 40 MPH SINCE I PURCHASED THE VEHICLE NEW IN JULY 2013. I HAVE HAD IT TO THE DEALERSHIP 6 TIMES, OF 4 TIRES ON THE VEHICLE THEY HAVE REPLACE 5 TIRES. THE VEHICLE STILL HAS THE VIBRATION AND AT HIGH SPEEDS, THE VIBRATION INCREASES. *TR

I HAVE A 2014 GMC SIERRA SLT WITH POWER SEATS. THE DRIVER'S SEAT IS LOOSE (NOT THE SAME ISSUE THAT WAS RECENTLY RECALLED WITH MANUALLY RECLINING SEATS). WHEN YOU MAKE A SHARP TURN AT SPEED THE DRIVERS SEAT SLIDES LEFT OR RIGHT DEPENDING ON THE DIRECTION YOU ARE TURNING. THERE ARE NUMEROUS COMPLAINTS IDENTICAL TO THIS ONE ON THE FORUMS ONLINE AND GM CLAIMS THEY HAVE NO SOLUTION AND TO SPEAK WITH THE LOCAL DEALER. MY LOCAL DEALER DOES NOT NOW KNOW WHAT TO DO AND SAYS THEY CANNOT FIX IT. THIS IS A VERY DANGEROUS SITUATION AND COULD CAUSE AN ACCIDENT! PLEASE HAVE GM FIX IT OR ISSUE A RECALL! *TR
