2013 Chevrolet Tahoe: sudden loss of power

Filed Jun 25, 2025 · Acceleration, Engine · MS

One day I was driving normal and my engine light and two other lights came on. It dropped my speed under 30mph and I couldn't pass the gas. It said reduced engine power, service stabilitrak and service traction. I immediately took it to auto zone then placed it in the shop at the dealership. They had my truck for almost 2 months and finally said they fixed it. It ran ok for a month or so. I was so scared to drive because it does it randomly. Boom it happen again now im frustrated because what is the problem. Called shop they said bring it back they will have a new person look at it. They had it for a month again. Paid more money. Then boom a month later the same thing. So at this point im calling no one is answering they ignored me so I called the customer service on the truck to complain. I had to get rentals and everything with the same problem it is over a year later. No answer and nobody called back nothing. I parked my truck for months and yesterday June 24th the lights came on again. I have heard alot of my friends and family say they have a chevy vehicle and they did/do the same thing.

While driving vehicle continues to drop into reduced power mode causing a jarring motion as it drops a significant amount of speed,almost causing multiple accidents. The check engine light comes on, traction control turns off, stabillitrack turns off, and engine goes into limp mode and starts shaking and jarring. The same 2 codes continue to come up in diagnosis. P2135 and p2176. I have taken the vehicle to three mechanics 1 of them being chevy its self. With no solution found. I have had the acceleration pedal replaced, the wiring replaced, the ignition switch and relay replaced had the throttle body connector replaced, the throttle body and gasket replaced 3 times. I have done everything recommended by all shops including chevy. Please help as the truck has been in the shop more then it has been on the road and I have almost been in multiple accidents as the truck is difficult to control when the issue happens.

Tl* the contact owns a 2013 chevrolet tahoe. While driving 40 MPH, the vehicle hesitated and lost power as if it would stall without warning. The air bag light illuminated and the vehicle did not respond when the accelerator pedal was depressed. The contact also stated that the radio powered on and off. The doors locked and unlocked on their own. The contact pulled the vehicle over, waited a few minutes, and proceeded to drive. The failure recurred. The vehicle was not taken to a dealer. The manufacturer was not made aware of the failure. The failure mileage was 40,000.

My wife and I bought a vehicle from cardenas superstore in pharr, tx. We've been to them 4 times, in which they've sent our tahoe to the local gm/chevrolet dealer in our area. Generally, when the weather is warm, stabilitrak and traction control will disable and we will see a series of warning lights. The ABS warning light will go off, the air conditioner temperature will rise to a warm temp, the locks will start unlocking and locking randomly, hard transmission jerks between first and second gear, and little power when trying to increase speed. The first time we went, they said they couldn't find a problem. The second time we went, they clean out all the fuel modules, the third time they couldn't find anything wrong. And finally, on the fourth try, the dealer couldn't find any issues so they put di-electric grease on some of the wiring. Two days later it started acting up again. A reason they may have trouble finding any issues is that after the vehicle is off for some time, it will start up and run without any issue. I've managed to get it over to the local autozone while all the panel was going off, and power loss, and they mentioned a few possible issues. The vehicles voltage regulator may be bad, as well as loss of communication from the ECM and many sensors(fuel pump, transmission, etc...). We are lucky that we bought an extended warranty on the vehicle or this could have become very costly for us. But none the less, safety is of a concern when driving the tahoe. Any guidance will be greatly appreciated. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

Over a period of 2 weeks, about 4 times, while driving in traffic including freeway. A sudden lost of all power, dash goes blank while door locks lock and unlock, in a blinking sequence. This happens in a time period up to 10 seconds, then the car continues driving with no problems or indicator warning lights. Took to dealer they test drove and put on computer, and nothing happened. Left it there 2 weeks no results. In blogs there are suggestions that when this happens to others, that it is possible that computer resets itself and wipes memory clean, because of power loss. They to take to mechanic nothing shows up. This is similar symptoms reported on recall #14515, but my car is 1 year older. It involves the chassis computer. My question here is if the computer is different from my make and model. This is a serious problem 2 of the 4 times this happened I was pulling on to freeway or changing lanes losing power. My daughter drives this car with her 2 twins in back seat. I have now exhausted all I can for a remedy with gm, the dealer who can not detect any problem. Started a case file with gm # [xxx]. No remedy or resolution. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
