I had ran into a similar issue. Light would blink when starting the truck, then remain on steady. I had it checked and was told it was the front air bag sensor. I did some research then fixed it myself. I found the two main reasons for this alert is either a collision or corrosion. Since I knew I didn't crash, I thought I'd check for corrosion. I found a video on the web from a company that sells after market sensors that shows you what the part looks like and where it is located. I located the sensor, unplugged and cleaned it, then I sprayed some corrosion protection spray ( I used battery terminal protector on it). I plugged it back in and it was good to go. It took longer to find the sensor than to fix the problem. The light shut itself off and I didn't have to shell out the money for a new sensor.
#1093 of 1099 po300b service engine code for 2002 Denali
May 26, 2013 (5:35 am)
Hi I'm having issues with my 2002 Denali. I have a po300b code. I changed plugs. When doing that I found all plugs to be clean and gray/tan. (maybe lean) I then cleaned the injectors. After a test ride the code came back. I tested fuel pressure and found 45 psi at idle, 55psi with vacumn removed. With vacumn removed the misfires on cylinder 2 and 6 lessened a great deal. Does anyone have any recommendations on further diagnosing the
fuel pressure regulator and pump. Any further tests to solve this issue would be greatly appreciated . Thanks

Last November (2012) I purchased a used 2009 Denali 6.2 with 39,000 miles from a Cincinnati GMC dealer. I now have 44000 miles on it and below this is what I have had to have fixed. I can not hardly believe it to be normal for these items due to age and mileage of car and the only thing the dealer here can say is that it is a higher end SUV and they just cost more to maintain. Is this reasonable?
1) November, replaced battery (Dealer covered, but at 39K miles?)
2) November, CD/DVD player internal optical head moves when key is off and sitting. I noticed it early one morning when I opened the door.
Dealer said this could be normal. I don't buy it.
3) January (ish), Turn signal audible notification quit working, 1/2 radio speakers (only front) quit working intermittently.
4) March, hooked up boat trailer for the first time and brake lights on trailer did not work. Had to replace another computer. Replaced a $700 dollar computer.
5)June, Service AirBag Message is now displaying.
6)June, Volt guage reading 15+ volts.
Is this to be expected? I can't honestly think that this is common. If so very poor quality if there is nothing else going on?
Any thoughts or experiences with this year/make/model?

Thoughts are GMC has some major issue with 2009 Yukon Denali
Purchased brand new, all service work completed from dealership. We have had major service work $$$. Takes a week or so for the Service Dept. to determine the problems. After reading this Forums - You would think they would be up front about how often these problem are.
Replaced Battery's -
Steering Column replacement
Rack & pinion assembly
Transfer case bearing
A/C motor Diverter
And in the morning it will be towed to the dealership cause of ELECTRICAL issues. Completely dead..... Nothing works. It's not the Battery! It can not be jumped.
Just wanted to let you know

Three days after posting this we have had a new one pop up. Cold starts in the morning it acts as it wants to stall and the Check Engine light is now on. AutoZone shows the code as a cold air injection system that forces air into the exhaust system is the issue. Just one more expensive item to fix in a SUV that has less than 50,000 miles.

#1099 of 1099 SUV not starting
Nov 07, 2013 (4:11 pm)
I recently purchased a used 2002 Yukon Denali. I was the only driver last night about 8pm, got out of the car closed and locked it up. Today I got into my car about 3pm and it wouldnt start. I noticed that the tow/pull button light was on my dash. I turned that off. And then noticed my hazards were on. Pretty freaky seeing how I didnt turn either on last night before going inside the house. Once I turned them off the car started no problem. Had to reset all my times and date but has this happened to anyone else or do I assume that someone got into my car overnight and didnt take a thing just pushed those two buttons...??
