On or about 10-14-2020 I had got a call from my niece that she was at a parking lot and the truck didn't want to run the same. She was passing a intersection when she heard a very loud pop noise and a very scary noise coming from the engine. The noise did shack her some but when she notices the truck had lost its power she was more scare that she was going to get hit by a other car came out to be the lifters and camshaft. Where they been having class actsions law suits with GM motors for the same problem with other GMC year from 2009-2015 5.3 vortex engins and GMC knew about it before the sold the very first truck its a $10,000 dallors repair and with the bank finance I will be paying more then $25,000 after cost and this truck blue book its at $15,000 last time I check it so its not worth putting so much more money for that year of truck. I had tryed to work things out with the dealership as well with GM motors and had no luck or even a call back from both sides. I ask that if you can investigate this matter some more I will gladly appreciate it. Thank you for your time.

Heard a laud pop and grinding noise on my 2013 5.3 vortex V8 GMC from the motor where I had to stop it because I thought my motor was going to luck up on me. I pulled over on the side of the road on Missouri and triviz. Where my wife had to pick me up 1 hour after the the fact to haul it back home. Got home where I did my research to find parts and labor coast for my truck and came across some active class action lawsuits on GMC for same tape of engine the 5.3 vortex and same and 1 year older or 1 year newer having the same problem. Where cases been open since 2016 and still open now for GMC to perform that kinda of engine to be called as a re-call. I then got a hold of GMC motors to see what they can do for me not being the only one with this kind of problem to see if they can help me in any kind of way and they respond was for me to take it to a certified dealer in las cruces, nm for GMC. I did just that then where I was rejected by the dealer because they had no information about what I and my wife just had discover back home. The reason why GM motors wanted me to take the truck was for them to do a full dynastic on the truck to see if it was the lifters that was wrong with it. Came to be it was the lifters and as well for the camshaft where they give me all paperwork about my truck and how much to fix it we are looking at $5,000 to replace the lifters and camshaft or $10,000 to put a new motor and the GM motors denied to help or to fix or replace the motor and camshaft or even try to meet me half way on expenses for my truck to get it up and running again. We got back home and talked to a lawyer that been fighting some cases since 2016 and added he added me to the others cases for the class action lawsuit for GMC not fallowing with there responsibilities for there action about the 5.3 vortex from 2012-2015 makes and models with this kinda of motors

Check engine comes in related to low oil pressure sensor causes an emissions light to which will not pass inspection. Have changed oil pick up tube O ring, which was not damaged, pressure sensor and screen have been changed. No mechanics or local dealers have any idea how to fix this issue. While driving the truck and stopped in traffic or at a very low speed the oil pressure light comes on.
