At around 100,000 miles, the check engine light would come on and indicate low oil pressure. Changing the sensor out did not effect the situation. Changing the oil would help but usually only for around 3,500 miles. The engine was losing oil more than it should. Then at around 129,000 miles, the truck starting shaking because of the engine and the check engine light came on. It was determined to be a cylinder 7 misfire. Changing the coil pack, spark plug, and spark plug wire did nothing. It was determined that the engine was irreparable and needed replacing. Upon research, it appears that this is a fairly common problem among 2008-2012 gm engines with the afm system. Gm should absolutely issue a recall and repair these defective engines or otherwise reimburse the owners for the repairs.

My truck died in traffic but I was able to get started and home (2 miles). My check engine light came on and I am reading a code u0191, which refers to the fuel pump flow control module. I had to purchase a battery because I had a battery draining issue and was having to jump it if it sat for a couple of days. My truck will not start at this time. After doing some checking, both my fuel pump and fuel flow module fuses are hot even with the truck ignition off. Which would indicate a short in the system. After some research , I found a safety recall that describes the exact issue but my VIN doesn't come up in the recall. Recall bulletin # 14515b . I guess what I am asking is why wasn't my vehicle included in the recall? Apparently this is affecting more vehicles that what the recall included.

Hit a pothole full of water with right rear tire while making a right hand turn. The water splashed up and entered into the fuel system control module through a poor seal causing the unit to shut off fuel to the truck. Truck stalled out and would not restart blocking two lanes of traffic. Check engine light was lit, and the truck had the following codes set: p069e, p0231, p025a, p064a. I had the truck towed to haydocy gmc and they diagnosed it as a faulty fuel system control module. They replaced and reprogrammed the new unit to the truck. They returned the defective part to me at my request and it was dripping water out of the seal. This is similar to recall 09v154000 for similar 2009 gm vehicles that were assembled in late 2008 just like my truck in which the seal was defective and would allow water to seep into the fuel system control module. I believe this recall should have included additional vehicle models including the gmc sierra. I would be more than happy to provide any documentation, pictures, or parts necessary to assist.
