AFM/DOD lifter failed while driving which causes multiple systems to go offline including Traction Control, stability control, ABS just to name a few. This happened while coming off freeway which can be a safety risk as vehicle was at higher speeds. This is a known GM problem with 5.3l engines and should have been addressed years ago.

Hello Our 2011 Chevy Silverado looks like it was sitting in a lake. The rusted frame has a hole and has failed Pennsylvania Inspection. The whole underside of the vehicle frame is peeling away the body of the truck is very clean. Truck has 60,000 miles and is garage kept. We were shocked to see the condition when we were at the inspection station. It worries me how many of these trucks are on the road or towing trailers. Please don’t wait to take action until something happens. Yes, our vehicle is available for inspection pictures. There was no warning lights. Our local Pennsylvania State Inspection Station failed the truck during routine yearly inspection. Thank you for your attention to this matter.

After 2 weeks of owning the truck which we are paying on it had to be towed 3 times stalling out and leaving leaving my family,my children with us at least once, and stranded in high traffic roads. We took it back to the dealership and they replaced the fuel pump and the fuel light came came on the very same day we picked it up. Now over a week after getting it back it has stranded us again,this time with our 3 children with us. This is on a Friday evening during rush hour. We manage to pull to a side road and off to the side a bit,but not fully. People are driving by very fast now as we wait for a tow.

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.

Unknown. I doubt this will qualify but it seems to be a very common issue so I feel it is worth bringing attention to. I recently bought a truck from a state action that was a prior police vehicle as stated by the title. Once I purchased it and drove it home I was inspecting it and found a rust spot on the frame. As I cleaned dirt and debris off of it I discovered that the frame from just before the drivers side door all the way to where it bends up at the gas tank was completely rotted out. Specifically the bottom of the frame is fully gone. Doing research into repairs it seems that this generation and brand of vehicle had this problem seemingly universally. Which leads me to think it may have been a defect in manufacturing. Due to the bottom rusting out it’s hard to spot unless you crawl underneath. I’m sure I don’t have to go into detail as to why a compromised frame that people could be unaware of could be dangerous.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
