I got the code p2138 and I’ve had it inspected and throttle body and accelerator pedal assembly replaced. The problem is still not fixed. I lost power driving to work and heavy vibration and shaking. If I pull out in a turn and someone is coming up fast and this happens again it reduces my engine power and could cause a crash. Problem has been confirmed by a licensed mechanic, AutoZone, oreillys, and an independent mechanic. There was absolutely no warning this was gonna happen. It happened and I’ve spent $3,000 on replacement and labor costs trying to figure this out.

Engine power reduced warning keeps coming on. As well as stabilitrak and traction control turns off. Code p2138 pops up. I’ve spent over $1,000 trying to get this fixed because it is unsafe to drive it like that. It will be fixed for 1 or 2 weeks and then it’s time to take it to the shop again. So many people have this issue.

December 2022, General Motors-Onstar system was deactivated in million of vehicles across America. This system was sold as a MAIN SAFETY and SECURITY system, integrated in millions of General Motor products was advertised as next generation Safety. This system allowed active subscribers the peace of mind that in the event of an emergency, they had us covered. motor vehicle collision detection for the event that you crashed, they could send first responders. If the vehicle was stolen, they had safe methods to locate and disable the vehicle. If you locked your keys in the vehicle with your child or pet, they could unlock it for you. In 2015 Canada "sunsetted" their 2G network which in turn would have disable Onstar for millions of Canadian vehicle owners across Canada. General Motors-Onstar offered FREE HARDWARE UPGRADES to keep Onstar active for whomever wanted and chose to keep the Onstar system working for them. Please refer to and What about the vehicles sold in America? What about the people who purchased General Motor products for the specific reason of Onstar peace of mind? The people who want the system to function as it should? What if I do not have my cell phone with me in a remote location and I crash my truck at 70 mph? No Onstar to alert first responders. What if I accidentally lock my grandchild and keys in my car? Must i now break a window instead of calling Onstar and asking for an emergency unlock? And a very important one for me as many others. What if my vehicle gets stolen. Now there is no way to locate it. There is no way for Onstar to SAFELY shut it down so it could be recovered. I paid yearly for Onstar services for that exact peace of mind as did MANY OTHERS. There is even a petition where people are saying that if given the choice, they, like myself, would gladly pay to have the system upgraded like they did for Canada.

Tthis vehicle was involved in 3 separate accidents, 1st another driver pulled out in front of the truck causing the accident; 2nd a driver fell asleep with his foot on the accelerator and rear ended me at about 90 MPH; 3rd an out state driver rear ended my son's car which was forced into the rear of my truck. The 3 accidents were severe enough that there should have been some type of air bag deployment but there was not. I notified gm immediately after the 1st accident about the failure of the air bags to deploy. I should mentioned that the driver's seat belt broke due the harshness of the accident. All this happened several years ago but gm never answered me nor took any action to investigate the failure of the air bags to deploy. Today, 4 march, I received a recall notice because after all these years takata has admitted there is a problem with the bags, except they say it is only the passenger air bag. To tell you the truth I didn't even think I had air bags because they never worked. The id number for this recall is 21v051. I am hopeful that even though these accidents took place years ago, I don't have actual dates because I didn't they were important, that you, as the federal agency responsible for overseeing the safety of cars using our highways, will inquire as to why gm failed to investigate a safety complaint submitted to their customer assistance center. Having some administration knowledge I am sure there has to be a file folder with my complaint in it. Thank you and please help me? * (recall related incident) ts

Oil pressure warning indicator alarmed, stating shut engine off immediately! Went repair shop close to home, a diagnosing test showed no codes at all. A check of bulletins for possible issue with codes that should be present, were not there? Shop has recommended I take vehicle to a dealership for further analysis.
