Multiple warning lights while car is running

[Sniko]

Today while driving my BRAKE warning light came on followed by my fuel guage going from half a tank to empty with a fuel light coming on and check engine light came on. I have 85000 miles on it. Its 2010. Put brake fluid in it and injector cleaner. Fuel guage still doesn't work, engine light still on. Brake light comes on intermittently. Anyone else had this problem? Any suggestions?

Wow sounds like data lines are intermittent.

It could be contact corrosion or wiring fault and

unless your experienced in those repairs I'm

afraid that your only out is a dealer visit.

Have you scanned it for codes?

Agree with jkeaton... With your CEL illuminated, there is at least one code, perhaps several in your case, and that's what those codes are for; to give you a short list of what the problems may be. Again, with today's newer cars an OBD II reader is going to be your best friend; even a cheap one will do. I carry two lower cost units (one in the DJ and one in the RAM) and I have a "big 'un" for major troubleshooting (catches live data, does "exercising" of relays and sensors, outputs to computer, etc.). If you are going to try and figure out what is wrong with today's vehicles, you need one.

In your case if you don't have one (yet), I'd swing by an auto parts store (AutoZone, NAPA, etc), they usually have a code reader and will either read the codes out for you or loan it to you to check them in the parking lot. Without the codes, for this type of problem, we'd be shooting in the dark since these electrical issues could be anything from a dirty connector, to a control module being toast.
