I was heading to work when suddenly smoke started pouring from the air conditioning vents, and the ABS and traction control warning lights came on. I hit the brakes to pull over, only to realize I had lost braking power. I managed to steer to the side of the road as carefully as possible and bring the car to a stop-despite having no brakes and a fire burning under the hood. I tried downshifting to slow the vehicle, but the transmission didn't respond, and the cabin began filling with smoke. Once I stopped, there was nothing I could do to extinguish the fire, as the car was completely consumed within seconds. It was a fire in the engine bay; I lost the brakes, and the ABS and traction control lights lit up. I assume it was a critical failure in the braking system, most likely involving the ABS module.

All the lights appear os dash. Tpms, taction control, maintenance check engine, , brake malfunction message power steering light. Car start beeping alarm. Transmision weard beheaving. Brakes weard, acceleration. Scare moments, stop the car. Dangerous driving. After 5 mjnutes problem desapear and afret 10 more milles problem appear again.

My husband took car to Rainbow City, AL location to have some recalls fixed. 2wks later we go to pick up the car & as we go to to leave, me following behind him, I noticed passenger brake light out. I call & tell him, then I notice the middle brake light isn't going off at all- it's staying lit. I then notice, when he adjusted the headlights the passenger brake light came on & driver side brake light went off. But middle brake light wasn't going off, it continued to stay on. I looked it up & it's a known issue with this model. I then look up for any further recalls and yes there are but my vin isn't attached to this recall as it obviously should be. …
