NHTSA Complaint #11498343 — 2016 HYUNDAI ACCENT

During hot/warm weather, typically 65 degrees or hotter, as soon as I turn on my car, the traction control light, the ABS light, and emergency brake light comes on. When this happens, the speedometer does not work. The gas level on the screen will also fluctuate, as well as the odometer stops counting miles. The car will still drive normal with all these specific lights, but is obviously extremely dangerous as the speedometer does not work. Sometimes when this issue is happening, if I drive around for 10 minutes, the speedometer will start working again and all the lights go out besides the traction control light. If I then find a spot to turn off my car and on again, it goes back to normal with no lights illuminated on the dashboard, the speedometer works, and the gas gauge goes back to what it is supposed to be at. However, at the same time, the issue might seemed to have fixed itself, but then will start happening again when I’m in the middle of driving. I tried taking it to Hyundai, as at the time this first began happening my car was under warranty still, and they told me my ABS connection was corroded, so they put in a new one. This did not fix the issue at all and the issue started back up again not even 30 minutes after leaving Hyundai. I had to leave town and couldn’t get the issue checked out again right after. This all started happening when my car was around 57,000 miles. I now have almost 75,000 miles and the problem still occurs. I have noticed that this only occurs when it is hot/warm outside and the car sits for a little, as stated above. I live in NY, so during the colder winter months, this issue never happens. This all is very worrisome when your speedometer stops working out of no where, or having the thought that it’ll get worse somehow when I’m driving at higher speeds, then all of this will put myself and others in danger on the road.
