| Off and on since last year i have had problems with my electrical system. just out of the blue the check engine light will come on and the reduce engine speed message will show up on the dashboard. and my speed will shut down and the vehicle will only go about 25mph. we had taken it in to a shop and they were unable to find the issue and said it was just a low battery. well after replacing the battery it continues to do this off and on. once the car is shut off and restarted it would be fine until the next incident. now while doing research on this issue i have read that many people are having this problem. some people have experienced this while on the freeway going 65mph. the engine will just reduce speed automatically. why is this not a recall for safety reasons? what has to be done for there to be a recall on this issue? | |||

| I have had multiple ongoing electrical issues with this vehicle. starting in 2005, the exterior electronics (i.e. signal lights, stop lights, head lights, etc) began to malfunction. for example, i would trigger the signal for one direction and all of the signals for all directions would trigger... even pressing the breaks triggered all of the exterior signals. the dealer had a hard time isolating my problem, but after several visits, the dealer was finally able to diagnose and rectify it... they isolated it to a junction box where all of the electronics terminate. however, by this time, my vehicle was out of warranty, so i had to cover the costs for reparing the problem myself. my most recent issues, which, by the way, seem to be common issues, are triggered by a message stating, reduced engine power. this particular issue does not always render the same results... sometimes the vehicle's speed will significatly decrease to nearly a halt, but other times i may just experience increased idling of the engine, even if i am at a complete stop. my understanding, according to hundreds of reports that i have read on the message boards, is that this issue is caused by either a wiring harness that leads from the excellerator to the throttle body or it's a defective throttle body alltogether. i have experienced intermittent electrical problems with my windows as well, but this appears to be a minor issue when compared to the other two that i addressed above. i will file a formal complaint with gmc corporate office today and see where that goes. | |||

| After noticing that my 2003 yukon denali had intermittent headlights/dash lights dimming, i took the vehicle to my local dealer to have it checked out. they presented me with a document that stated the gm stated this was not a malfunction and was a normal condition. there is nothing about this that is normal. any time, at night, a curve is taken at above 35 mph the lights flicker. i had already pinpointed that it had to do with the vses system because when the vses is turned off, this does not happen. when a curve is taken and the flickering occurs, the voltage meter for the battery drops substantially and then goes right back to normal. this is a distraction for the driver (myself), any oncoming traffic, and anyone that i am behind. this absolutely needs to be looked into before it causes injury. *jb | |||

| While driving at night the headlights and dash lights flicker off and on. this condition only occurs while traveling at speeds above 35 mph and when hitting a bump or making a curve. this condition is not only distracting, but when driving at night with no other ambient light i am unable to see adequately ahead of my vehicle. i have had drivers ahead of me pull over thinking that i was flashing my lights at them and other drivers get irate believing that i am bright lighting them. this is a safety issue that appears to be widespread on the denali's with stabilitrak. gm states that this condition is normal. i believe that headlights are meant to burn steady and not flicker off and on. i am requesting that nhtsa investigate this with the auto manufacturer to mandate a fix before there are injuries attributed to this condition.*ak | |||
