   On Sunday June 7, 2026 my husband drove our 2014 GMC Acadia to work. We both work at MSY - Louis Armstrong New Orleans International Airport for United Airlines. After he parked in the employee garage that is located in at the old terminal and got on the employee shuttle, the passenger tail light sparked a fire. Airport operations responded with the fire department that is stationed at the airport.

   Vehicle is randomly stalling or going into limp mode when driving. Has done it in intersections, driving down the hight way and even stopped in a parking lot. No warning but throws codes unrelated to the problem. I’ve been told that it shuts off half of my engine randomly while running and that contributes to the stall. Can cause accident if stalls while turning or even if in wrong lane on high way. You loose all power steering and basically have to coast to safety.…

   Vehicle stalls intermittently. Due to an earlier recall of the same model but not including the one I own. There is electrical shorting inside the fuse box in the ignition circuitry that causes this problem. This is a huge problem as there is no preemptive warning. Whether you're driving 5 mph or 55 mph it happens suddenly and without any warning. The incident is stored in OBDII codes. There are no warning lamps until after 5he vehicle stalls out. #PIT5643.

    I took my 2014 GMC Acadia into the dealership I purchased it at because my airbag light was on. This was before the recall. I was told at that time that nothing was wrong and and I probably hit a bump and juggled something loose. I paid $190 for that. Now my vehicle is in the shop and I can no longer operate it or sell it because it is deemed unsafe due to this recall. I contacted GMC and there is no remedy for this. It has been 8 months. This is not timely. They would not…
