Steve,
Have you tried to reset the DIC settings? If not, I would recommend trying that. Here is the information I found:
 
EXIT LIGHTING
This feature allows you to select the amount of time you want the exterior lamps to emain on when it is dark enough outside. This happens after the key is turned from ON/RUN to LOCK/OFF. Press the customization button until EXIT LIGHTING appears on the DIC display. Press the set/reset button once to access the settings for this feature. Then press the customization button to scroll through the following settings: OFF: The exterior lamps will not turn on.
30 SECONDS (default): The exterior lamps will stay on for 30 seconds.
1 MINUTE: The exterior lamps will stay on for one minute.
2 MINUTES: The exterior lamps will stay on for two minutes.
NO CHANGE: No change will be made to this feature. The current setting will remain.
To select a setting, press the set/reset button while the desired setting is displayed on the DIC.
 
APPROACH LIGHTING
This feature allows you to select whether or not to have the exterior lights turn on briefly during low light periods after unlocking the vehicle using the Remote Keyless Entry (RKE) transmitter.
Press the customization button until APPROACH LIGHTING appears on the DIC display. Press the set/reset button once to access the settings for this feature. Then press the customization button to scroll through the following settings:
OFF: The exterior lights will not turn on when you unlock the vehicle with the RKE transmitter.
ON (default): If it is dark enough outside, the exterior lights will turn on briefly when you unlock the vehicle with the RKE transmitter. The lights will remain on for 20 seconds or until the lock button on the RKE transmitter is pressed, or the vehicle is no longer off. See Remote Keyless Entry (RKE) System Operation on page 2-5 for more information.
NO CHANGE: No change will be made to this feature. The current setting will remain.
To select a setting, press the set/reset button while the desired setting is displayed on the DIC.
 
These directions are also in the owners’ manual. I hope this information helps. Let me know if this solves your problem.

Hello barnowl3,
 
Given the age of the vehicle, the face that the brakes rusted again outside of the 12 month/12,000 mile replacement part warranty, and the amount of time that has passed, I do not think that a reimbursement would be likely (however I cannot say this with absolute certainty). I know that this is not what you had wanted to hear, and I'm sorry that I was unable to assist further; in my previous post I was giving you the procedure for pursuing reimbursement.
 
I wish you well,
Sarah

Yes, tried this. It refers to the exterior lighting and not the interior lighting. Thanks

Christie, Thanks for your help. Fixed it. Turns out there is a dome lamp override button that got turned on by mistake. Found that because it was in the instructions.... duh! And here I thought I had read them.... Thanks again

i had a similar problem on my 07 sierra it would probably be the fuel valve purge solinoid. gm put it ina dumb spot its right under your drivers side in between the front and back doors cant miss it.. its a little black cannister with a line going in and a line going out and an electrical connector... when replacing it be careful not to damage the hoses... i did and the code for a leak came on.. i put electrical tape about 12 inches down both lines and it went away all good now you will replace about 2 of these if you own your truck for more than 10 years..

Hello All,
 
I am having an issue with my 2010 Silverado LTZ, 4WD, Crew Cab Z71. The problem started as follows: day 1, Mileage 37400: Drove my truck to work and parked it, no issues. I went to start it at the end of the day and the truck would not start. I looked down at the info window which said "SERVICE 4 WHEEL DRIVE". We tried to troubleshoot different ways to get it to start with no avail, until we removed the battery cable for 30 sec and replaced it. Everything was back to normal. I brought it to the dealer to have them plug it in just to make sure everything was ok. Unfortunately that was not the case, the computer was reading 12 communication errors. Needsless to say I was now 1400 miles over the bumper to bumper which apparently "electrical falls under" GREAT. After about two days of tracking down each fault and a day to replace the Transfer Case Control Module they got the faults to clear and I got me truck back. Two days later I was driving down a dirt road (luckly I was only doing about 5 mph) the brakes locked up on their own and then the fault lights lit up. Service 4 wheel drive, service abs, service stable trak, check engine, service traction control). This time the vehicle remained running but was stuck in 1st gear. I disconnected the battery and once again everything was gone. I brought it back to the service center and this time there was 18 communication faults. 4 days later I got me truck back with a brake control module replaced. Ran fine on the way home. Today I drove it to my sons school. When leaving I started it up and notice that my fault lights were lit up again. Additionally it would not shift pass 1st gear, the gear selected indicator was not on, the speedometer, rpm were not working. Is anyone else had issues like this and if so what was to end point fix that actually worked. The service station is definitely trying to help and are currently working with me on the bills. But I thought I would try to help them with idea's.

It sounds like your truck is doing weird electrical things like my was. For me, it turned out that a main grounding point on the frame had come loose and was sending fluctuating voltages to the ECM's. If you haven't noticed already, for some stupid reason GM weather coats their frames with some sort of wax junk. My guess is that they come to the factory already waxed and then the assembly begins. My frame is a rusty mess due to water and ice getting between the wax and the steel frame in the winter. Then it freezes and the wax literally comes off in sheets, leaving large sections of steel unprotected. It looked like the ground points on the frame were never scraped down to bare metal before the wires were connected and when the water got behind the wax and froze, the ice pushed the wires out just enough to make the connections loose. The most noticeably loose ground was the one on the outside of the frame directly under the drivers door. It is just behind the front tire and get a direct hit from the road spray. My guess it is a loose ground. Good Luck!

Thank you for taking the time to post your experience and concerns. Can you please email me directly with your VIN, current mileage, involved dealer, a brief description of your concerns (or a link to your post), and complete contact information? I would like to look into this further for you.
