ABS, traction control & Brake Lights are on
Weirdly my abs, contraction control and brake lights come on spontaneously flash on with a ding. Then goes away only to happen later in the day. When it’s acting up the speedometer drops and the lights on dash and headlights seem to lightly flicker. Any help would be appreciated!

Use a scanner that can dig in to the modules and see what ABS code is thrown. It won't store as a generic OBDII code, but there will be a code store deeper in the ABS module....starting with a "c". It should pinpoint which sensor triggerd that. Many apps that operate with a BT dongle can read these codes.

My son's '07 was doing that for a while and the code that popped up said bad ABS control module. $$$ :-( Well, I also noticed an antifreeze leak from the transmission cooler was spraying all over the inside of the brakes. A can of degreaser and a pressure wash later and no codes for the last 5k miles.

Don't spend any money until you first check the health of the battery and it's connections. A bad battery is known to cause random dash light issues as well as speedo and tachometer behaving strangely.
