Ok so I have a 2007 dodge 2500 6.7 liter mega cab all stock with 126,000 miles on it never had a problem but after my last oil change required light came on I did a full service fuel, oil ,air, and all. I pressed the peddle 3 time like normal the light went off but now every day for 2 weeks now it comes on every time I start my truck I can't keep it off. Is there something else to do besides take it to the dealer?

 

This guy had the same issue.

Then he realized he had the switch in the ACC position. He repeated it and it went away.
2002-2015 Dodge Ram 1500 / 2500 / 3500 Oil Maintenance Light Reset

To turning off the Oil Life Light on 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2013, 2014, 2015 Dodge RAM, conform to the following instructions:

• Turn the ignition key to position “ON” without starting the engine, If your Dodge Ram has push-button start, press the “Start” button twice without touching the brake pedal.
• fully depress accelerator pedal slowly three times within 10 seconds
• Turn the ignition Off

 

Every time I do the reset I do it in the run but not started position. I have done several services on my truck this is just the first time I can't get the light to stay reset. It will reset when I do it but after I drive around like to the store or something get back in my truck it comes back on.
