  1. "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
  2. So I had a bully dog tuner for my truck and haven't had it plugged in since I got a new engine installed a few years back. Found it today and found someone who would buy it. Contacted bully dog and found out that I would have to change my tuning to "stock" to be able to unlock the device so the guy could buy it from me. I told them that my truck was already stock and they said that I just needed to run the stock tune to be able to unlock it. So I did that and it cut my engine power and turned off ABS and Stabilitrak. Cant go over 25mph, truck shakes, sounds weird. I have no idea what to do and their customer service is closed for the night. I have work in the morning, any suggestions?
  3. I am a long time GM customer and currently own a 2009 GMC Yukon Hybrid truck. It has been an ok experience but just recently the truck started to do some strange and unsafe things. It started out revving up without pressing the pedal or hesitant to accelerate after stops and then moved on to stalling in the middle of driving and would give me a warning of REDUCED ENGINE POWER, SERVICE STABILITRACK AND SERVICE TRACTION CONTROL but would only do it every blue moon. Here recently I was leaving somewhere and the car begin to shake and shake and then stalled out after those codes popped up. I called the dealership and set it up for an appointment. They got me in and the day I was taking it to them it gives me the reduced engine power warning and I noticed the car went from a rough idle to an even rougher idle increasing more and more as I'm driving. Finally I hear 'CLUNK' and then all of a sudden its not just a rough idle, the engine is shaking VIOLENTLY. I turn the car off. Other times when the car would give me the warning of engine power being reduced, I could turn it off and wait a second and turn it back on and it would magically reset for a random time period before it did it again. I was about 2 mins out from the dealership so I made my way there and as I'm pulling it the engine starts to do that crazy shaking thing...everyone literally stops and stares at me, probably trying to figure out if I'm about to blow up! They get it in and the tech is super alarmed by that shaking and said he had never seen or heard anything like it. They pull the codes and replace the throttle body position sensor under an extended coverage offered by GM. After they fixed it, I'm notified that one of my engine mounts broke and I now have to produce $1,000 to fix it!!! The engine mount is what broke during the engine freak out during the 20 minute drive to the dealership because I heard it! When I get my car back it now wont go into hybrid mode anymore and its idling super funny... up and down...up and down and I can now feel every shift the engine makes and the start up and turn off even rattles now and my engine ran so smooth before this you could balance a penny on the engine! I'm so upset because GM says this is my out of pocket expense. However this only occurred because of their defective part! I'm taking it back in whenever the dealership calls me back(been waiting for hours) and they will see why the engine is idling unevenly and "recheck their work". I'm so sad and after talking to a GM rep who so rudely informed me that they did their part on fixing the throttle body and to just shovel out $1,000 that is not not their problem, it s actually a point of frustration. My husband and I have own 6 GM cars that were a pleasure to buy and drive but we will never buy another GM car again!
  4. Hey guys I need some help. I've got an 07 NNBS Silverado 5.3 Last week I used my remote start for my truck and it fired up and quit. The remote start wouldnt work so i went and started the truck with the keys. When i did this it started up and idled horribly in with the DIC reading "Engine Power is Reduced" I plugged in my diablo tuner and read the codes. I had a P2176 and P2101. I cleared the codes and the truck started up and ran normally. I drove the truck all day and it had some advancements in the idle. The rpm's would race in neutral and park. Anyway i researched it. Cleaned the carbon out of the throttle body and the truck straightened out. A couple days later not two miles from my house while driving it went into power reduction mode. This time only the P2101 and P1516 codes showed up. I cleared them. fired up and was on my way. This happened one more time that morning. After more research i ended up bringing it to my local gmc dealer for an idle relearn. After this the truck idled much better and has run fine for the past couple of days. Now its been at least 200 miles since i had the idle relearn done but today i was on my way to work itwent into to Power reduction mode. This time the only code to come up was the P1516. Same thing i cleared it and i was good. I am not just confused. The other two codes were related to the TAC. The only code now is the p1516- "Intake Manifold Runner Control Input (Bank 1) See P2014." What do you guys think?!
