Why are Check Engine light and zigzag road drive not vanishing from the dashboard?

Well the check engine light and zigzag lights are probably connected - the zigzag light is probably for traction control.
If there is a problem with the engine the traction control warning light will come on too so the driver knows it is disabled.
You would need to have someone check the engine computer for trouble codes to know what to test.

My 2006 hummer h3 keeps shutting off and saying no traction reduced power

The anti lock and slip sensors may be dirty or damaged causing misinformation to the vehicle computer.

2006 chevy impala traction control

Reduced power is a problem with electronic throttle contol . drive by wire . Do you know what this is ? Taking the vehicle an having it hooked up to diagnostic tool an checking for DTC'S - diagnostic trouble codes is always a first step when trying to find the root cause of any trouble light ! And not auto zone , pep boys , or advance auto parts . Thier diagnostic tool will not check codes in all system control modules .

Reduced engine power light, Engine light and Traction control system warning light are all on

Yeah I have the same problem. The Check Engine, Reduced Engine Power Light and TC Control Light are all on at the same time. It will go off by itself after a few days and then comes back on. I've tried disconnecting the battery and that has worked in the past but this time it is not working. Anybody have any suggestions?

Traction light and and engine power reduced warning came on. What should i do?

You do the same as with ANY light you get on the dash
of ANY vehicle made in the last 30 years

You check for codes & diagnose & repair code related issues first

For most people ,that will be done at a local repair shop

The traction light issue is part of the ABS Braking System
& thus the reduced power which on some vehicles cuts out
the injectors when the rear brake get slammed on etc

All MFG have different ways the systems work

Got to get it fixed in few days,because it is the
electrical part of your braking system

Engine power is reduced keeps showing on the dash screen, as does service traction control. the car is running rough and has no power when this occurs.

how do you fix the "reduced engine power" light on the dash bard of a 07 Chevy Impala LTZ and "Service Traction Control"?
