Off the top of my head I would say the control module isn't functioning correctly

If it is the same as a 2008 GMC Yukon with conventional power, it comes out of the front wiper fluid reservoir!

More than likely the DVD player is defective.

Hi, maybe you have a faulty water pump or gasket, it's better that a mechanic check it as soon it's possible.

I not sure what the problem is but I do know if you back up over five miles per hour the park assist will shut down in reverse and you will get a message to that effect on the dash. I had the same problem with one of mine and the dealer told me that it is designed that way to shut down. Try backing up under five miles per hour and see if you have the same problem. Hope this helps.

I would go with Quaker State high mileage oil. Use he manufacturers recommended viscosity. I hope this helps

Your local dealer should have a replacement 'tab' which can sometimes be soldered back onto the glass. Sometimes it just doesn't work and the glass will need to be replaced. I have done many of these, it is a 50/50 shot

Sounds like you need to have the pressure checked with a mechanical gauge. Make sure the oil pressure sensor is in the loop when you do so the fuel pump will run.If the pressure is normal when the engine is warmed up, it could be something with the instrument cluster.

get a haynes manual for it at a parts store or on ebay,it will tell you what you need to know and do and is well worth the investment

Changing tires from the OEM size will cause this,and many other problems as well. Such as steering and handling. You will also be driving faster than your speedometer say`s.Shocks and struts and all the suspension parts will wear faster.Maybe the dealer could remove that display.

take it to your local garage and have them read the code with a obd code reader
