65,300 miles on my 2016 Chevrolet Silverado with the 5.3 liter engine. Engine lifter and camshaft failure due to the AFM/DFM system. Now my truck is being worked on as we speak by a performance shop who says these seem to be a normal occurrence. Some with more miles and some with less millage. After doing some research online, this is a very common problem. And on TikTok, Instagram, and Facebook there is a lot of people having same issues. My question is why isn't this being looked into. I've asked other mechanics, speed shops, and including a Chevrolet Dealer mechanic and he said yes that AFM/DFM is a major problem. But no recall from GM. Please help. This is not a cheap repair, and It's definitely unfair to many others that will have these same issues.

Engine camshaft is out only 105k on vehicle. $6k to fix for it to just happen again which these trucks are known for this which is a huge manufacturer flaw. Driving down the hwy and check engine turned on quickly and whole truck shaking had to pull over going 60mph small shoulder on hwy. Taken to 2 mechanics both told me have to pull heads replace camshaft lifters. For this to be a known issue with these motors they put out and cost people thousands and risking safety is unreal

It is commonly known the Chevy 5.3 and 6.2 engines have lifter problems. Not sure why there has not been some sort of recall done already.

The 2016 silverado LTZ 5.3L flex fuel lifters went out at 83k miles. I was left standed and had to be towed. I have researched that this is a known GM issue with the 5.3L motors, but I was told because I was outside the warranty that I had to pay the $8000 repair bill for a new motor. This is one a GM issue and a safety issue because I had sudden no power while I was driving and with no warning. The second issue is that the brakes have a serious shake and vibration that the dealership told be they were fine, but it is very hard to stop the vehicle with a tremendous about of force I had to place on the brake peddle. The life of this vehicle has had all services done at Jim Mckay Chevrolet in Fairfax VA. I could not afford the repair and unfortunately I had to trade in the truck and buy a new truck with large monthly payments.

The truck has had its major service to replace all fluids at 70,000 miles. One of the services was a notable vibration and shaking through the steering wheel and on the brakes. Higher the speed the more the vibration. When brakes are applied the vibration gets worse. The vehicles brakes and rotors were checked and good. The mechanic said that the brake pump was slightly loose and it was tightened. It did slightly ease the vibration, but less that a few days later it is back to the same vibrating. The brake power feels weak and when I need to brake I feel like the vehicle is not stopping. I have owner a 2014 Silverado before this and did not have this issue. I took it back to the dealer and they did an alignment which did not help.

I brought my truck into the dealership for a routine oil change. They notified me that my radiator is leaking and needs to be replaced. They stated that there is a small leak in the lower right corner of the radiator. I did not notice and fluids leaking from the radiator prior or did not smell any coolant from the engine. The leak did not trigger any warning lights inside of the vehicle. I did notice on a few occasions that the coolant levels looked low and added more to the system. My truck only has 60k miles on it. After researching this issue I've learned that this is a fairly common problem for 2014-2018 Silverados and that Chevy will only fix the 2014's.

AFM/DOD leafters collapse

My truck has a shudder/ shake while accelerating as well as rough shifts here and there. If certain speeds are maintained, the shudder is constant. This causes uneven speeds, noises, and distractions. I fear one day the transmission will fully give out while driving and I will crash. My vehicle is available for inspection. The problem is easily reproduced as it happens every time I drive. As well, the truck was recently at an independent service center and the problem was confirmed by an associate. The vehicle has not been inspected by the manufacturer as they told me it would cost me $180 just for a diagnostic which they will need my car for two days. There are no current dash lights on. This is a known issue and Chevrolet should be held accountable.

I developed a oil leak in my oil cooling lines. I don't know why there is a recall for the 2019 Silverado and not my 2016 for the same problem. I reference GM Customer Satisfaction Program number: N212326940.

The lifters on one side of my engine failed. This is due to the AFM(Active fuel management) system that GM had in its vehicles from 2016-2021. My truck is a V8 motor and the AFM system drops the motor to 4 cylinders during periods that the vehicle is in stop or coasting. Overtime the lifters in the engine wear out causing the engine to fail. I barely made it to the dealer to fix the issue as I lost full power in the engine nearly causing me to have an accident. The only notification I got was check engine light started blinking mid-stream on my way to work. The cost to repair lifters is extremely high and that is the reason why GM hasn't issued a recall yet. There are thousands of cases of failed lifters in my research online. GM knew this was a problem as they have quit using the AFM feature in all of their vehicles. My servicer at my dealership even told me that they have seen this problem on multiple occasions.

Only way I found out that fuel pump wasn-??t working was due to transmission problems with sensor and having to get the whole harness replace as well as the Moyer I had to get the motor replaced as well engine light kept coming out and truck felt lost of power and would waste gas a lot, safety wise I was afraid it-??d break down in the middle of road with my family trucks been having problems since I-??ve got it with motor and transmission and fuel pump problems, yes problems have been confirmed with dealers but dealers just say they fixed it but continued to have problems so I took it to certified shop and having them fix the fuel pump and transmission problem, as of I know the truck has been inspected by warranty company, yes they-??re were warnings like engine lights ABS lights.
