Engine power reduced, service stabilitrack
2 months ago I have had the issue of service stabilitrack followed by engine power reduced. My truck gives my a fault code of MAF sensor fail. I've replaced the TP sensor maf sensor a new stock intake and recently and new ecm with the same associated faults. along with upgrades or re work to my ecm before the mechanic told me to replace it as well. The technician says he can't find any faults or issues in the wiring or with the truck but the issue is still there.

I have a similar issue, first I saw engine light came on. Checked the codes P069E, P0641, P06A6. Then a few starts later, am getting service stabilitrak and traction control off. But doesn’t say reduced engine power. For a little bit there I was getting service tire monitor system, but that was kind of intermittent and seemed to have gone away. ABS light also came on at the same time as service stabilitrak and service traction control..
P069E - fuel pump control module requested illumination, P0641 - sensor reference voltage “A” circuit/open, and I believe the P06A6 is just to do with PCM - Powertrain Control Module...
My 09 silverado is a 4.8, 2WD, have only put on a k&n cold air intake. I believe I had something replaced under the seat. That was a recall a few years back. Possibly FPCM? Is it under the seat. Just regular cab, no back seat. I read the FPCM could be under the spare tire?
I have had a few issues initially starting. Where it starts then dies but fires up the second time. Have turned the key to let it prime and then it seems to start up and run fine.
Any insight would be much appreciated. Have to get back and forth to work next few days but booked an appointment at dealership for Tuesday. Hoping I can figure it out and cancel it. 105 an hour labor seems expensive. Would love to be able to fix it myself.

Seems to be a common issues across all models
So I have spent the last few weeks searching for any recalls or extended warranties on this same exact problem which has started happening to my 2010 Chevy Silverado 1500. I have only 69,000 miles on it and keep it serviced regularly. Last week while traveling at about 68 mph on the highway I was a victim of the what I now know is the dreaded REDUCED ENGINE POWER, SERVICE STABILTRACK, SERVICE TRACTION CONTROL. My truck immediately dropped to under 30 mph on the highway and thankfully the guy following behind me was able to slow down in time before rear ending me! I immediately hit the internet to see what this could be and my god this is an issue that is so widespread across these vehicles it is absolutely horrible. Not only did I find hundreds of people reporting this issue, the "fix" seems to be even worse. People taking their vehicles to the dealership and being charged hundreds of dollars for them to take a stab at the issue with most people requiring multiple trips. At this point Chevy/GM is well aware of this issue and are doing as little as possible to fix it. I have registered my issue with the U.S. DOT National Highway Traffic Safety Administration (as have plenty of others) but I am hoping GM/Chevy step up to the plate on this one a do the right thing. I also came across a few people that are in the process of starting class action lawsuits for this issue.
