Today my abs light went on and the brakes became rock hard could not press down on them. Then I parked the car checked all fluids and belts, turned the car on again the abs light turned off. Started to drive tried accelerating from 25mph to 30mph then esc light went on locked my breaks tried driving to park in a safe place as soon as I parked the car and turned it off a bad smell and lots of smoke came out of my front tires and rear tires. Got car towed breaks are ok my mechanic pressed the esc button off and now breaks are soft. I believe there is a malfunction that you should look into that will cause a recall. Also tpms light randomly goes on and off. Tire pressure again is fine. Please consider looking into this. It's the only car we've had for about 9 years and now my daughter drives it to school. Safety please!! thank you, dalia.
