Vehicle shuts off when stopping. Everything goes dead. It will eventually start again, but very annoying. What happens when it shuts off going down the highway? No power steering or power brakes, that's what!

I heard a sharp click like metal on metal, then I lost all power from the engine. I was on the highway close to rush hour and I was trying to move to the right side of the road and get off on the shoulder, the engine would start long enough to get off the road and then that was it. The engine was dead. I called for a flatbed tow truck through my insurance. I had no idea as to what had happened. However, I have read many reports of engine failure concerning the 5.3 v8 engine which I have. The Chevrolet Silverado 1/2 ton pickup was towed on a flatbed truck to Chevrolet, They found that the engine had dropped a valve in the #7 cylinder and some rocker arms, etc also had broken. The final billing was $7092.89 I was in traffic going around 60mph when the engine died and put me in an emergency situation. This could have caused a wreck. Several warning lights came on because of a dead engine. I do not believe any rep. has inspected the parts as this has become a common serious problem, it is all over the internet however I have not seen a Recall at this time. I sincerely believe GM should be responsible for this as it has been happening for years and years. Thank you for listening

I purchased a Brand new Chevrolet Silverado 1500 LT Z71 in2015. While still paying on this vehicle I had an issue with the engine bogging down and it would almost die. It would jerk and shake terribly to the point it just shut down. I took to Royal Chevrolet and they found that it had a broken Valve spring on Cyl 7. This went on and on they had this vehicle for a total of almost 7 months before they put 1 last engine in it. The 1st thing I did was drove down From Michigan to North Carolina to visit my daughter. Plenty of Mountains and a lot of driving as I drove 14 hours straight by myself. The engine that they had just put in started Chugging and choking and it stalled on the highway going through the mountains and I was hit in the rear end and the other driver never stopped. I managed to get it running again. Prior to leaving for North Carolina I ordered what they call a tuner where I could deactivate the AFM system and stay in 8 Cyl mode at all times. I had it sent to her house. I installed the program. Keeping in mind #1 I was rear ended. And every single time there was an issue it was Cyl#7 on all the previous engines. I talked to the Lead man at Royal chevrolet about all the issues and he said they know all about it and its a joke. They tried it on Cadillacs back in 1975 and recalled every one of them and turned it off. On my way back home not 1 single issue in fact and I sill have it displayed on my dashboard I actually got 26.2 Miles per gallon in V-8 mode in the mountains. I have driven to NC every year since before I even owned that truck and have never seen milage before or since. The AFM system is nothing but a ploy to get people to buy junk. Could someone been killed? Most certainly. I told the manager 1 more engine and I have a Friend cut stickers of lemons out and put at the main 4 corners in our town. I still have that truck and currently have 128,000 miles on it and I had to pay $600 to fix it myself. And GM thinks its a joke. I called

I bought the truck around [XXX] from Barkau CDJR, Freeport IL. Two hours away from the dealer the truck went completely dead in traffic. A message appeared on the info screen that said roll down the drivers window and back up to reset the system when the truck finally restarted. Got home with it and called the dealer and let the know. In the next few weeks it happened a couple of more times. It was taken to Tapper Chevrolet in Paw Paw, MI to be serviced. The tech thought it was a problem in the fuse Block and replaced that, after that on the week end the truck was returned the problem happened 3 times. Took it back to Tapper's and they checked it again, had it for 4 days and could not replicate the problem. Kept having issues and took it to 1st Choice Automotive LLC in Dowagiac, MI, he went through the wiring and cleaned some grounds and it seemed to work for a while. Now it is doing the same thing again. It just shuts down randomly for no reason. You lose steering, brakes, you have no control when it happens and no warning when it is going to happen. Have searched You Tube and have seen many other complaints of the same problem with no solution. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

With only 32,000 miles the active fuel management system went out. The lifters failed and caused internal engine damage. My vehicle was well maintained using only high quality synthetic motor oil. I am on the hook for over $5000 in engine repairs. This technology was a miserable failure and the consumer should not be held responsible for poor engineering.

A 2015 Chevrolet Silverado seemed to be running rougher after an oil change. When inspected by dealership, Litha Chevrolet located 200 East Cypress Ave in Redding CA, they identified lower end knocking and lifter ticking noise. Also identified was PO300 was randomly missing and PO324 Knock Sensor performance. The dealership recommended total engine replacement, after reviewing the report. The 2015 Silverado is currently out of commission. It is not roadway safe. The Silverado has been serviced regularly as recommended and has not been in any collisions in the past. The truck has had one owner previously, my father, who left me the truck when he perished. I relied on the truck for daily and extended transportation for myself and my children. I have maintained excellent care of the 2015 Silverado with regular maintenance and services. There is no explanation of this issue other than it was caused by faulty equipment from the manufacturer. If you can provide any information regarding how to fix this please contact me. Thank you

2015 Chevrolet Silverado 1500 with 5.3 liter engine developed coolant leak. Took vehicle to Chevrolet dealer and they said the radiator was failing. According to the service advisor, this was a result of the thermostat "over cycling". They also said GM had a recall for this exact problem for the 2014 models but not for my vehicle. Cost of new radiator and replacement of the defective thermostat was over $1,200.
