Updating: My car (Journey 2011/2012 SXT) had the brake assembly (Rotors / Pads) replaced with
20,000 miles. I bought a set of EBC Rotors and pads (Yellowstuff).
I drove about 7,000 miles and the rear rotors get warped, and shake the wheel is back (only between 100-120 km / h).
Despite the car being under warranty, I got tired of the dealer, then I took the car to a repair shop specializing in brakes.
The rear rotors were resurfaced, the front rotors are ok.
Now I'm taking the car to the repair shop specializing in suspension to try to figure out the problem once and for all.
