GMC Sierra 1500 Problem Report
GMC Sierra 1500 Daytime Running Lights Are Prone to Burning Out
The daytime running lights are prone to burning out. Our technicians tell us that the light sockets may show signs of heat damage but usually are OK. Always be sure to use the correct replacement bulb for the best life expectancy. The new bulb recommendation for 1999-2003 models is #4114K (trade number).
My running light always go out it does not burn out sometimes it stays on and sometimes is goes off if you wiggle it a little it goes on but as soon as you hit a bump in the road it goes off. I see so many trucks that only have one running light on that I can't count them any more. They are GMC and Chevy. What can I do??????? - Visitor
Went to replace a burned out daytime running light and discovered that the sockets for both of them are blackened and charred. Looking into replacing the sockets and trying LEDs. - Visitor
Have had to replace both running lights at less than 50,000.The worst vechile purchase I have ever made. - Visitor
Just same problem as everyone else. But as normal with GM when you contact them with a vehicle concern
they claim it is operating within GM specs. Well, do I need to explain how i feel about there specs.
Was always a GM person since hitting the road in 1969. When its time for my pick to have a new owner
there will never be another gm vehicle in my garage due to their loose operating specs. - Visitor
socket adaptor burn out. - Visitor
I bought this truck used with 121000 miles on it. In 1000 miles I have had to replace the light once and now at 122000 need to replace it again. This is such a common problem that you would think GMC would look into it and come up with some kind of fix for the issue. - Visitor
Actual mileage is actually numberous various mileages due to the fact that I have replaced bulbs many, many times, particularly on the passenger side. Very frustrating. - loyal gmc owner
Passenger side driving light was out. Sockets on both sides are burnt. When new bulb was installed it would not work at first. Had to remove socket assembly then reinstall it, jiggled bulb some and then it stayed on. Bulbs seem to burn very bright and are very hot. Has me concerned so I am keeping an eye on both sides for further deterioration of socket. I don't think the original bulb burned out as the elements inside bulb were ok. More like a socket problem. - Haulmarc

right side running light was the first to burnout. couple months later the drivers side burnt out. now two weeks later the right side is burnt out again. bulbs are supposed to be replaced in pairs only is what i was told, mine weren't. what i'm looking for now is #4114 cre or #3157 cre. - Visitor
same as every one else-I quit changing the bulbs, they started burning out sooner after I changed the first set. I have driven a general motors vec. from a 1947 truck to my 2000 Silverado and have never had as many problems as I have with this truck. - Visitor
one daytime running light burnt out on my chev silverado - Visitor
This seems to be a common problem for the daytime running lamps, i have found that the majority of the time that the bulb blows due to water getting into the light housing. Check the light housing for signs of cracks or holes and then seal those areas with a water proof seal. I have done this and it seems that the bukbs don't blow out near as often.
Hope this helps - tinkman03
Owner before me had the wrong bulb installed. The bulb socket seemed brittle which I think was the reason why the old bulb was hard to remove as was the new bulb hard to install. - Visitor
