My traction control system light turns on what is wrong?

Get ready for a journey it gets worse our 07 does the same thing been doing it for a year have cleaned throttle body several times and it helps but eventually comes back..Was told now needed to replace the whole throttle body assembly...So i replaced that today will update on how it runs...Oh and this is a super common problem in the 07 and other years even other models its very dangerous at times..Gm/Chevy may be the worst vehicle ive ever owned..Sitting at 90000 miles
