Giving it a boost should work. Could be a bad battery or a short in the electrical system causing a 12v draw which will run the battery down.

Moisture and weather is a killer? try cleaning the eye with a Q tip if not it means that the eye is to far out of the resolutions from the weather exposure. Che the dealer for an advice.

memory has to flashed by the dealer

I recently had a low engine power on my 2003 Denali. The check engine light came on and I couldn't go above 40 mph. I took it in the next morning but by this time the check engine light had gone off. The mechanic had just recently seen the same problem in another Denali in which they changed the battery and had no problems since. I also decided to have them change out my battery and I have not had the problem since either. I would stay away from the dealership if I were you, and always get a second opinion. Most smaller shops wont charge for a diagnostic where the dealership will charge at least 80 just to tell you what might be wrong and that will only work if you have a warning light on at the time.

It means you should take it to the dealership so they can check the pressure in the system and reset the sensor.

contact the dealership where you purchased the vehicle

TRANSMISSION FLUID NORMAL TEMPERATURE IS 200 DEGREES.

We had the same issue with our 2007 Yukon Denali XL. Died on us twice after sitting for short periods of time; once we watched a DVD with the engine off and battery died within 10 minutes. The dealership kept it overnight to troubleshoot why the battery died so quickly. They said the radio was "pulling" too much from the battery. (They supposably fixed it) But again a few days later the battery died again after sitting overnight. We brought it back to the dealership and they brought in a GMC "expert" to replace the entire DVD/CD/Navigation system. They also replaced our battery with a much larger battery, similar to the ones that GMC puts in there diesel trucks. They had our Denali for 5 days, but it appears to be fixed now.
Getting it fixed correctly wasn't without headaches, but it was all covered under warranty, including the battery. And they are updating the nav w/ the new edition disc as well for no charge.

I shipped my 2006 Yukon Denali from USA to Saudi Arabia. When I to purchase the Middle East map DVD for the navigation system. GM Navigation answered me that they do not have the middle east DVD and I should contact the European branch. The dealer in Saudi Arabia is asking for $1200 for the disc and I know it is worth no more than $400. Could you please direct me to someone who sells the 06 Denali navigation map DVD? Thanks..
