When I started my car this morning the ABS warning light came on, traction control was turned off and the fuel gauge does not work. The check engine light has come on about three of the six or so times have started it. The car was fine when I parked it. I have done several searches and found different things that may be causing the ABS malfunction, but nothing that shows how it would be tied to the fuel gauge or check engine light. The only code Autozone was able to get was for a bad fuel level sensor, but the chances of that going bad at the exact same moment as the brake issue seems too coincidental. Otherwise car runs fine mechanically and all other gauges work, including the MPG estimation, even though the "Fuel range" reads 0. I disconnected the battery for about fifteen minutes with no luck. Any help is greatly appreciated! I do not want to just start throwing hand fulls of $200.00 parts at it. 2009 G8, 3.6 V6

Auto parts stores cannot pick up ABS codes, and this could be a sensor bad or a piece of rust is on sensor as they are magnetic. As far as the fuel gauge goes it may be what the auto parts picked up or dirty battery terminal ends or bad battery, so have that check for condition including load test. A battery in poor shape will cause false codes.

Thanks for the information. They did a short test on battery as well and it checked out okay, and I have not had any other electrical issues. The battery is located in the side of the trunk and terminals look like new. Just seems strange that two completely different parts would go bad at the very same moment. I appreciate the insight.

Ok so Ive actually seen this before. I actually just worked on a newer Nissan Rogue last week where as soon as the check engine light kicked on, the ESC light kicked on as well at the same exact time. The ESC light is part of the ABS system. The check engine light was on for a bad Mass Air Flow sensor but I also scratched my head as to why the ESC light turned on as well. I had no codes in the ABS system. So I just performed the obvious first and was going to tackle the ESC light concern after. I replaced the Mass Air Flow sensor and then cleared the check engine light. To my surprise, when I did that, the ESC light also went away. So for some reason, Nissan has it designed for some reason to kick on either when the check engine light kicks on or if its based on which diagnostic trouble code kicks on. I don't have the proper information to find that out for you but a quick call to any GM dealership may clarify it for you. I would replaced the fuel level sensor since thats an obvious problem and go from there. Best of luck.
