2011 Chevrolet Silverado 1500 fuel system problems

Filed Jan 31, 2025 · Engine, Fuel system · TX

The software that makes the truck work as a 4 cylinder truck has caused the engine light to come on and causing a code P0300 various engine misfire. The misfire is caused by the lifter spring causing the lifter to remain in the down position. The down position is against the can rod and as the cam rod rotates, this causes the lifter to break at the bottom and causing the can rod to also break which will cause an engine failure while drinking and the motor will freeze . All GMC and Chevrolet vehicles with this installed should be recalled. Everyone has been fixing it themselves by replacing the part(s) once a pinging noise is heard at 50,000 miles. Basically every 50,000 this will need to be fixed. Some people are turning off the 4 cylinder software to avoid the problem which in both cases, uses more gas and also idles higher.

Fuel leak at the fuel tank. Pulled tank from the truck, found the fuel pump housing was completely rusted out. Upon inspection of the pump housing, the high pressure line was rusted out and almost off the pump, causing gasoline to pump out and all over. After replacing this fuel pump I inspected the frame and found the frame looks like a frame off a truck that is 40 years old, not a truck that is only 12 years old. The frame has heavy levels of rust down thru from the drivetrain back. There are spots that are rusted completely thru the frame where it looks like a crack down the frame. Most of the rust is on the bottom side or inside area of the frame. This area with the rust crack will have to be repaired very soon for safety of the vehicle, because if the frame would happen to fail where this crack is, the truck would fold in half, and if it is being driven on the interstate it would cause a major accident for sure. The rusting is so extensive that instead of repairing the spots, it would be more feasible to just go ahead and replace the whole back half of the truck frame. This is unacceptable for Chevrolet to use material that craps out so fast on trucks that are supposed to last many years, instead of falling apart long before they are even paid off. A 12 year old truck shouldn't have this extensive amount of rust damage to the frame. I would just fix the frame if this was commonplace for trucks, but my 2000 Dodge Ram has a frame far better then what is under my 2011 Chevy Silverado as far as rust goes. 2000 Dodge surface rust in spots, 2011 Chevy completely rusted thru in spots. My next inspection on this Chevy will more then likely remove it off the road unless the frame is repaired. Unacceptable from Chevrolet and for only a 12 year old truck. I added pics of the frame right in front of the fuel tank, which the frame shows that long rusted crack down it. Can send more pictures of the frame in other places if needed.

One night on the way home from work, I was driving 60mph and all of the sudden my truck hydroplaned. I managed to get the truck straight and regain control of the vehicle. About a week later, as I'm heading home all of the sudden my ABS, brake, and traction control lights all illuminated. The dic reads service stabilitrak and service traction control, then it will display stabilitrak off and traction control off. I had the codes read and my trouble code was p069e - fuel pump control module requested mil illumination and u0073 - control module communication bus a off. All those lights mentioned above have been on for about a month. I looked up information about the fpcm and found out about gm recall 14515, I entered my VIN but the only recall that came up was for the takata airbag recall. As I read through the 14515 recall, I feel my truck is affected by it because, while driving the truck my speedometer jumps all around and is not stable. Also, when I try to accelerate, it feels like the engine stalls and there's no power there. Other times, it will down shift to increase rpms, but then soon shift gears into a higher gear then shift back into a low gear and repeat this until I let off the pedal. My tow haul mode will not stay engaged, cruise control will not stay engaged, and most of the time my truck won't even start when trying to use the remote start, instead lights just flash as I'm holding down the start button on the key fob. The truck feels really sluggish almost like there's no power, it seems like it hunts for the right gears while driving. Overall it just feels unsafe to drive.

Vehicle went into limp mode while cruising at 65 MPH. Traction control disabled light and check engine light illuminated. Message center displayed "service stabilitrak" "service traction control" and "engine power reduced" messages. Vehicle slowed and transmission downshifted. Vehicle failed to accelerate while depressing the accelerator pedal. With accelerator to the floor the vehicle would not exceed 35 MPH in a flat grade. On a steep incline the vehicle would not exceed 15mph with the accelerator pedal to the floor. The issue has occured several times before. Parking the vehicle on the side of the road and several ignition cycles have in the past have resolved the issue. This is a known issue with gm vehicles using a drive by wire throttle body and it has been recalled on other model years.
