Car has been working like a champ with no problems. I was coming home with my 2 kids and when I came to a red light my dash lights came on. My thermostat dropped to zero, my service light, theft system, and check gauges lights came on as well as my gas needle dropping like ticking on a clock. When I released the break and got on the gas all lights disappeared, thermostat jumped up to normal, and my fuel needle started climbing back up. Breaking felt fine. Well today I went to the store. Car started normally except my service light, break light, trac off, and check gauges light was on. Couldn't tell if the thermostat was normal since it was still warming up. But even while driving the lights stayed on the whole 4 blocks to the store. Leaving the store the lights didn't come on until I came to a red light. Lights that came on yesterday popped up again. When I pulled into my apartment parking spot I pressed the break a little harder to see if the lights would come on and they did but went away. These lights are coming and going, I had no issues with this car and it's my families only means of transportation. Please help. Posted pics below in comments.

this may be due to a bad battery/charging/belt. Have battery checked for condition including load test they can check charging as well make sure terminal ends are clean on battery then because of your mileage the belt and tensioner should be changed as it's recommended at 60,000 mi for both and it may be slipping. if it continues get it scanned by a mechanic.

I also heard it could be ground wire or a battery tray? I know my tray is all rusted to bits and is very loose.

if anything it would be a ground besides the battery you would need to check ground wire under battery tray and right side of steering column
