Greetings to everyone Recently I have made few fixes in my 2017 GMC Yukon and my fixes was in the car suspension and control arms due to a very strong vibrations in the middle console and after the mechanic was done I asked him to take a look at my lane assistant because it hasn't been working properly for a while so he hooked up his obdII diagnosis and started reprogramming and learning for the steering assist and front camera module (which is located at the windshield behind the mirror) little did we know these issues will appear after he is done, so before the reprogram process I had no lights on the Dash at all, only when I started the vehicle I get (service parking assist) but it wasn't an issue for me, so after he press learn on his device ABS, traction control and stabilitrak lights all went on suddenly like Christmas lights and ever since it didn't go off and he couldn't fix it back even though he tried to do all the learning and programming of the device and his diagnostic said it was successfully learned but the faulty codes kept coming back. I attached the obd diagnostic report and hope anyone could help Also in the report I saw new to me codes like HVAC and radio weird codes even they're working fine 2017 GM Vehicle Diagnostic Report_1GKS17EC5HR103833_2024088181503.pdf

"ENGINE POWER REDUCED, SERVICE TRACTION CONTROL, SERVICE STABILITRAK" Has anyone ever came across this before? Let me start from the beginning. On 11/2932013, halfway on my drive from work to home, I noticed that my truck would "sputter" and the rpm would fluctuate when giving it some gas while going up a hill/incline (interstate). Once I was done with the hill/incline, everything would smooth out. Closer to home, once again, I would only notice the "sputter-like" reaction and rpm fluctuating slightly when giving it gas to climb a hill/incline. Made it home fine with no problems or warnings/lights. Upon embarking to work the next morning (11/30/2013), at approximately 5-6 miles from home, I went to give the truck some gas to get above 60 and all of a sudden all these warnings and dings starting going off. My engine warning light illuminated and my traction control light came on and I noticed some warnings scrolling through at the bottom saying: "ENGINE POWER REDUCED, SERVICE TRACTION CONTROL, SERVICE STABILITRAK". it blew my mind! Meanwhile, I noticed my truck slowing down no matter how much gas I gave it. I was coming to a road intersection just ahead and preceded to turn around and pull over to investigate. I couldn't understand what was going on so since I was close to home, I just "limped" it back home and not getting over 40-45 mph. Got home and shut engine off and called my job. I went back out later before my ride got there to pick me up, and started my truck. It started fine and I didn't notice any "sputtering" like before, however the engine light is still illuminated. I can't do anything until this Wednesday anyway. Is there someone that has come across this before? The day it happened I Google'd to my heart's content and found that I am not alone, however I did notice that there can be a number of things that could cause this. Would any of this be covered under a warranty? How would I know if I still have warranty on my truck? I need some expert advice on this. Here is my truck info to the best of my knowledge: 2010 Chevrolet Silverado 1500 LT Taupe Gray 5.3 L V8 Crew Cab Any help will be greatly appreciated! Thanks, R. Ashley
