Hoping someone can help! This car is making me insane.
Its a chevy equinox, 2012, about 130,000 miles.

The Abs, traction control, stabiltack, and engine light come on.
We had the diagnostic machine on it and it said wheel scensors so we changed those, then we changed the wheel hub assembly on both sides, they are still on. Also a red circle with an exclamation point comes on and dings forever, so im assuming something is serious, but im not sure what is left to replace? Brakes, roters were also just changed.
When i first start driving it you can feel the brake pedal like pulsing and its loud, but as soon as the dinging stops it doesn't do it anymore.

Also we changed the camshaft scensor and my engine light went off, but after we changed the starter the light came back on. Any ideas for that?

Thanks!
