I have a 2011 Sportage EX, which has just under 49000 miles. A couple of days ago, the downhill braking light showed up red on my panel as well as the ECS light, after sitting for an hour or so at home they both were off when I restarted the car. Now several days later, I start my car to go to work, and they are both back on. Any ideas as to why? I bought my car used from the local Kia dealership and only have a 50,000 mile warranty. I am going to make an appointment to have it looked at immediately.
