I'm following up on tracking number 11642264 that was submitted on Feb 12th for my 2012 GMC Sierra 2500 HD ignition lock issue that fits the profile for a current recall . I haven't heard anything and am checking on the current status. Thank you. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2012 GMC Sierra falls under recall number 14V827000 Ignition lock activator by year, make and model, but not by the VIN number. I called the GMC 800 number and they indicated that the NHTSA issues the recalls not the manufacturer. I then called the NHTSA and they indicated that the manufacturer issues the recalls. I just need to have VIN number [XXX] added to recall number 14V827000. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving on the expressway around 60 mph when the truck went into limp mode slowing me down to 40 and then would not shift gears Tcm went out gm told me that there is a big problem

Truck is a diesel. Fuel pump blew up and died in the middle of the street. Now I'm being told the Fuel system needs completely re done and will cost me 10g. I also found a lawsuit for this issue as well.

Failed TRANSMISSION CONTROL MODULE (24256861). While driving in the early morning hours (darkness) taking my child to school, I was navigating through a busy intersection when the vehicle surged and then made a loud metal on metal sound, feeling as if someone had struck me from behind. At that point the power train became inoperable, stranding us and coming very close to being first, struck from behind and then from cross traffic. The vehicle was/has been inspected by a GM technician at Starling Chevrolet, St Cloud, FL and the TCM was found to have failed (trouble code U0101, lost communication with TCM). It has been at the dealership for going on four months awaiting the production of a replacement part(TCM). There was no prior indication that the TCM was about to fail. Upon failure, all lights on the vehicle display flashed and the indicator for the vehicle drive position was lost (P, R, N, D), no longer visible.

I received notice of a defective front airbag in February, 2021. As of now (about 7 months later) no action by GM to repair.

WHILE TRAVELING ON THE INTERSTATE AT SPEED AND PASSING SLOWER TRAFFIC; ENGINE POWER FELL OFF, CHANGE FUEL FILTER NOW, ENGINE DERATE, AND CHECK ENGINE LITE, OCCURED. I HAD TO MANEUVER WITH NO POWER THROUGH THE TRAFFIC TO GET OUT OF THE TRAVEL LANES. I WAS THEN STRANDED ON THE INTERSTATE AS THE TRUCK WOULD NOT START. I WAS ABLE TO GET A MECHANIC TO COME AND CHANGE THE FUEL FILTER ON THE SIDE OF THE HIGHWAY, BUT THE TRUCK WOULD NOT START. THE TRUCK WAS EVENTUALLY TOWED TO A SHOP WHERE IT WAS DIAGNOSED WITH A CATASTROPHIC FAILURE OF THE FUEL PUMP (DIESEL MOTOR DRIVEN PUMP).

FUEL FILTER HOUSING CONTAINS A PRIMER PUMP. NEEDED FOR A DIESEL. SEALS WITHIN THAT PUMP FAILED ALLOWING AIR INTO THE SYSTEM. VEHICLE IS 8 YEARS OLD AND ONLY HAS 67K MILES ON IT. THIS CAUSED THE MOTOR TO QUIT WHILE IN MOTION. IN YELLOWSTONE PARK.
