Default Help??

Gas gauge suddenly dropped 1/4 tank and now read 1/4 low all time
Filled tank, needle indicated just below full always read correctly until now.
Drove maybe 15 miles gauge now reads 1/4 low, in fact you can see needle dropping as you drive.
No leaks, no gas smell
Seems to want to read 1/4 low now, running some fuel injector cleaner thru system, dirty sender unit maybe??
Also remote no longer opens rear hatch.
any idea how to correct that with out having dealer reprogram it
Thnx

Default could be>>>

an electrical gremlin....a reboot could be in order. Disconnect the negative battery cable and let sit for a few minutes. Make sure to have your radio security codes...

Maybe the battery in your fob too...

Techron could not hurt the fuel senders....

Default try some Techron...see if that helps.

i would probably try that a few times. if not, could be the dreaded fuel senders and/or cluster failure. the rear hatch may be a coincidence more than a related failure. check your fuses as well.
