I get the problem is traction control and that you're having trouble with reduced engine power but the post was too hard to understand to get much more out of it.

Can you repost a better description of the problem? If you're using a mobile device, that might be why it's hard to read. Try posting from your desktop PC.

Were you looking for the DIC to tell you something or did you actually use the DIC buttons to display any trouble codes?

Codes said nothing , what happens is driving on freeway tc on by default the dic will say active handling engaged then it starts to lose power kinda like when it goes into low power still dic says nothing.Its like it ran out of gas ,hit tc and take it out of tc runs normal.Also if takeing a wide sweeping turn will prevolk all this. Thanks dadaroo

If you pull the codes after you turn the engine off there are some related to the EBCM and PCM that will not show up unless they are hard locked in as C or Current.

What size tires are you running? For TC to work correctly the rear tires must be 1/2 to 1 1/2 inch larger in diameter than the fronts.

I will do some research in my files and see if I can come up with any further ideas.

PS: Have you done anything maintenance wise like alignment, etc prior to this problem?

Dadroo you just fixed it. short on bucks. i bought a bought 2used run flats for the rear and looking at them they are smaller, car is parked not with me so i cant run the size by you. But thank you for the answer .I learn something new every time i sign on. Thanks

You can use the guidance at Tire Rack to calculate the diameters. If you need any help post the tire sizes and I can do it for you.

Good luck, keep us posted.
