Headlights problems of the 2008 GMC Envoy

The contact owns a 2008 GMC Envoy. When the contact started the vehicle, the low beam headlights did not work. There were no warning indicators illuminated. The vehicle was driven home using the high beams. The contact also stated that the vehicle experienced the same failure two other times. The vehicle was taken to the dealer for diagnostic testing, but no failures were found. The manufacturer was notified. The failure mileage was 119,000.

While operating the 2008 GMC Envoy on an interstate I observed what appeared to be a lack of light when the low beam headlights were turned on. I drove to a rest area and confirmed that the low beam headlights were inoperative. The bulbs were removed and both bulb filaments appeared intact. Fuses, breakers and relays were checked for secure seating. The high beam headlights were operative and all other lights functioned. I am aware of documentation that covers the issue but only up to the 2007 model year. There are other complaints on file describing similar issues. The unsafe condition that resulted was the absence of forward lighting while operating a motor vehicle during times that lighting should be used. It is my belief that a solid state relay, delco part number 15016745, in the #46 position in the engine compartment fuse panel, is apparently the cause of the lighting failure. No injuries, or damages resulted from the in operative low beam headlight issue.

Low beam headlights on my 2008 GMC Envoy denali randomly turn off by themselves for extended periods of time and then turn back on the next day only to turn off again. This happens when driving at different speeds. Also stability track signal comes on for no particular reason.
