all brake warning lights are on but no code set.....cruise not working at onset of this problem
Getting various dtc codes pertaining to 02 sensors, p0137,p0138,p0139,p0113,p0296,p0152 all at different times with different combinations.
All dashboard idiot lights lite up and say lit until engine is turned off. When restarted they may or may not come back on. Sporadic problem.
abs lights on and cruise not working but brakes seem to have no problem
ABS service 4wd light comes on ...car does not have any mechanical issue
It seems there are a combination of issues. The check engine light has come on and stays on; the indicator of "Check Gas Cap" has come onand stays on; The change engine oil has come on and is staying on (though I should still have a little over 1000 miles to go before another oil change); and the low tire inflation light has come on. I bought this vehicle used from a dealer back on the last of March 2014, and have taken it to them four times to date to try and repair. They have changes the TPS sensors, a sensor in the gas tank vent, and replaced the seals in the rear differential and added an additive to stop what sounded like gear chatter. However, after getting the vehicle back within a couple of days, the same dash panel light come pack on. Is there any way to help the dealer find the problem and fix it?
The warning is about the front differential-
