I have a minor problem which I hope can be fixed.
I had my oil changed at the dealership but now for some reason when I drive a Long time or uphill my oil light comes on the dash. Then goes back off. I've checked the oil level and it's fine. I was wondering if maybe the oil pump is going out or the sensor is going out or ?
please let me know if you know.
thanks

 

Welcome to HF.

First, you have to post your question in the correct section, so I moved it for you. The Hummer Forums Help & Suggestion section has NOTHING to do with any vehicle, it is for questions on how to use the forums..... like: How do I post a pic of Grandma waxing my rig?
