Lower power while driving.
We have a Tahoe with the same issue. Turns out that usually happens when we are in auto wheel-drive. We stopped using auto mode. Still not 100% solved, however
No recall . Reduced engine power is caused by a problem with the electronic throttle control . Having the vehicle checked for DTC'S - diagnostic trouble codes would point you in a diagnostic direction . Viewing videos on how the system works an testing would help .

SOURCE: Why does my tahoe keep displaying reduced engine
There is a service bulletin for this concern.The number is 07-06-04-019A.It has to do with the body harness instrument panel connector.It is on the left hand kick panel area inside the instrument panel.You should have the codes checked.You will probably have a P 2138 code.This is for the accelerator pedal position sensor 1 and 2 correlation.Hope this helps.
SOURCE: my service traction control light keeps on going
I have a 2006 checy impala and the TCS ( TRACTION CONTROL SERVICE) liught came on..What does this mean?
SOURCE: reduced engine power on
The traction control uses the speed sensor in the transmission and the wheel speed sensors to determine wheel spin. If a wheel spins braking is applied to it so that the power can be transferred to the other wheels. At some point the ECU detected a gross disagreement between the sensors and so as a precaution has entered into a limp home mode. On some systems if the fault is in error it can be cleared by putting the car into drive and moving forward a meter, putting in reverse and going a back a meter and doing this three times. If one or other of the sensors are faulty this process will not allow the error to be cleared. You need to check or have checked the error codes and the speed sensors.
SOURCE: error message "reduce traction control" and then
Thwe check engine light is on because the computer has detected a problem. Take the car to Autozone and they will scan it for free and tell you what the problem is. If you have a question, let me know. I am here to help you.
