While driving in a parking garage and going down a ramp to the next level, all of the lights on my dashboard popped on and the brakes stopped working. The emergency brakes failed to work, and we crashed into a wall/air conditioning unit. Luckily, we were going slow since we were in a parking garage and did not hit another car, but if we were on a highway and/ my entire family were in the car, someone could have died not only in my car but in other cars. The vehicle has been inspected by the dealership, but only after 3 weeks, and I've had to call to get any sort of communication from Kia. They have been horrible with communication. They also have not offered guaranteed reimbursement for a rental car nor have they offered a loaner. Insurance has inspected the car from a collision perspective and gave a quote on the damages. There were warning lights on as we were going down the ramp when the brakes went out.
