The Active Fuel Management Lifters can cause catastrophic failures by getting stuck in the closed position causing low oil pressure, misfiring, and ticking due to the entire AFM system making the camshaft and valve train wear faster. It is available for inspection upon request. My safety is put at risk due to the possibility of causing accidents or leaving me stranded in an extreme environment. Issues with AFM (Active Fuel Management) systems in certain GM vehicles have been widely reported and confirmed by both dealers and independent service centers. Specifically, AFM lifter failures and related issues, particularly in older models, are common diagnose The vehicle component has not been inspected by anyone.

Cylinder 6 misfire. The mechanics have replaced everything that could be triggering the cylinder 6 misfire and still it is having problems they said the only way to fix it is to replace the engine but I should not have to replace an engine with low miles and that has been babied. I have also looked on multiple sites with people who own the same truck and all have the same exact problem with the same cylinder. Something needs to be done about this issue especially if it’s a reoccurring one, either have a recall on it and fix it or something.

The Trucks equipped with DOD system also known as Active Fuel Management in the V6 and the V8 engines cause the truck to consume more oil and cause lack of oil to the lifters which then fail and cause the truck to lose power and smoke really bad and can cause the truck to die while driving and when you love engine power it can cause an accident it's also can cause the more internal engine problems I have reported this issue before for and nothing has happened then problem needs to be fixed is a design flaw and can cause an accident which could also get someone killed along with the bad airbag on passenger side GM needs to take responsibility and fix this issue please for the safety of anyone who drives the the vehicles with the V6 or 5.3l V8 please get this issue recalled.

After buying this used truck from GM certified dealership having advanced inspection before we took home 3 months in First start of the day about 7AM, 5-10min into driving, no MIL light, truck engine shut off hard to pull over and I tried to restart but wouldn't start. After waiting an hour for a tow truck I tried once more and it fired up. Cancelled tow drove home fine. But it did it a few more random times while driving until Oct. now it sits. Its scary when theres no MIL indicating a problem, but this is a problem and safety during travel. It wont start after 7 month ownership ,MIL light is now on saying U0100. Bought 4/2021.
