Hello everyone new to the community and new to Chevy trucks. I'm looking to purchase my first Silverado in the near future but after researching the current gen Silverados I keep seeing how afwul afm is in these trucks and how in extreme cases it can lead to engine failure. Can someone explain to me exactly what what the problems are that owners are seeing with this technology and my big question is, have a lot of the issues been worked out or even resolved in the 2017-2018 models? Are the problems with afm severe enough to not make it not worth getting a new Silverado? All the bad things I am reading are really pushing me away from buying one . Any and all information is welcome !
Thanks guys !
Two easy ways to turn off the engine auto start system in the Chevrolet Silverado 1500 since they do not give you an off switch
here's the video link let me know if you have any questions
My 1999 Chevy Silverado 1500 4x4 lost all oil pressure, and then a little later engine shut off. Did not make any loud noises, It just died. When we went to restart it, we could here the starter engage, but the engine wouldn't turn over. So we had it towed, and the guy at the tow shop put a wrench on it and tried to turn it, but was unable to. We have done no further troubleshooting, this happened on January 1, 2018.
We assumed it is seized.
What I am wondering is what you guys think, is it likely that it seized or is something else more likely to be the problem? If it is seized what part would have seized up? And would it be better to rebuild the engine, or to put a new engine in it?
The truck has about 200k miles on it, and ran perfectly before this happened.
It is the new body style, btw.
I don't know much about this system, how it operates, the stress that is placed on the lifters during cylinder deactivation. How common is this failure? Been watching some YouTube videos on the repair and it's very labor intensive...heads have to come off, etc. I see that you can buy the entire kit (lifters, gaskets) for around $500.
Have a friend that told me...just change your oil, you'll be fine. The number one cause of this failure is neglected maintenance. That true? Or is it an inherited problem with the design of the system?
The system came out in 2007, there must be some improvements made to it since then, no?
I must say that the AFM is allowing me to get some excellent fuel economy out of a full size truck.
So is this a common problem, or are there people with 200,000 on these trucks that never had an issue with it?
Ordered a RANGE AFM Disabler today after reading through this forum and others.
I don't drive many miles per year - my '14 has a little over 23,000 miles on her - purchased August '14.
Truck goes in and out of V4 a lot. Just can't see it helping much with the hills around here and my short trips.
