2007 GMC Envoy exterior lighting problems

“Headlights go out on there own and may come back on a few minutes later but right back out again. The vehicle had this as a recall but if it was repaired the repair is not working. The manufacturer is claiming the recall expired, obviously without them making contact to do the repair. Now they think it's good business practice to ignore their problem and put customers lives at risk.”

“The contact owns a 2007 GMC Envoy. The contact stated while driving approximately 60 MPH and also at other speeds, the low beam headlights became inoperable. The contact was able to activate the high beam headlights to continue driving. The contact stated that the failure with the low beam headlights was intermittent. The contact stated there was no warning light illuminated. The contact had not taken the vehicle to a local dealer or independent mechanic to be diagnosed or repaired. The contact purchased replacement bulbs for the vehicle however, the failure persisted. The contact researched and related the failure to NHTSA Campaign Number: 15V519000 (Exterior Lighting) however, the VIN was not included. The manufacturer had not been informed of the failure. The failure mileage was approximately 153,000.”

“The contact owns a 2007 GMC Envoy. The contact stated while driving 70 MPH, the headlamps became inoperable. There were no warning lights illuminated. The contact stated she turned on the hi-beam and was able to continue to drive the vehicle. The vehicle was taken to the dealer; however, the dealer did not diagnose the vehicle. The dealer advised the contact to bring the vehicle in whenever the failure reoccurred. The contact stated that the failure had been reoccurring intermittently while driving. The contact contacted a second dealer Poage Chevrolet (851 W Pearce Blvd, Wentzville, MO 63385) who advised the contact that her vehicle could not be repaired under NHTSA Campaign Number: 15V519000 (Exterior Lighting) since the VIN was not included in the recall. The manufacturer was notified of the failure and confirmed that the VIN was not included. The vehicle was not diagnosed nor repaired. The approximate failure mileage was 145,000.”

“THE DAYTIME RUNNING LIGHTS (DRL) AND THE LOW BEAM HEADLIGHTS DO NOT LIGHT EVEN WHEN THE DASHBOARD LIGHT SWITCH IS PLACED IN THE 'HEADLIGHT' ON POSITION. TROUBLESHOOTING REVEALED THAT THIS FAILURE WAS CAUSED BY THE BODY CONTROL MODULE (BCM) LOCATED BENEATH THE REAR SEAT. A DIGITAL LOGIC SIGNAL FROM THIS MODULE, BASED ON SENSOR INPUTS FROM THE AMBIENT LIGHT SENSOR, PARKING BRAKE AND WINDSHIELD WIPERS, IS PROVIDED TO THE UNDER-HOOD ELECTRONIC RELAY THAT ACTIVATES THE HEADLIGHTS. THERE ARE THREE POSSIBLE SIGNAL OUTPUTS FROM THE BCM...A LOGIC LOW (LIGHTS OFF), A LOGIC HIGH (LOW BEAMS FULL ON) OR A PULSE WIDTH MODULATED SIGNAL TO CREATE THE DIMMER DRL LOW BEAM INTENSITY. IF THE BCM FAILS, THE LOW BEAM HEADLIGHTS WILL NOT TURN ON. THERE IS NO AFFIRMATIVE INPUT TO THE ELECTRONIC RELAY FROM THE LIGHT SWITCH, NOT ROUTED THROUGH THE BCM, TO ACTIVATE THE LOW BEAM HEADLAMPS. THIS IS A MAJOR SAFETY ISSUE. WHEN THE BCM FAILS AT NIGHT, THE DRIVER HAS NO LOW BEAM HEADLAMPS. THE ONLY LIGHTS AVAILABLE ARE THE FOG LAMPS OR THE HIGH BEAM LAMPS, BUT ONLY AFTER SETTING THE DASHBOARD LIGHT SWITCH TO THE HEADLAMP POSITION. HEADLAMPS ARE A NECESSITY, NOT A OPTIONAL FEATURE.

“WE HAVE A 2007 GMC ENVOY, INTERMITTENTLY OUR HEADLAMPS AND DAYTIME RUNNING LAMPS WOULD CUT OFF AND ON, SOMETIMES WHILE WE HAVE BEEN DRIVING IN THE CITY AND ON THE HIGHWAY AND SOMETIMES RIGHT WHEN WE PUT THE VEHICLE IN DRIVE BEFORE WE MOVE. ABOUT A WEEK AGO THEY CUT OFF AND HAVE NOT EVER CUT BACK ON. WE FOUND ON THE NHTSA WEBSITE THAT THERE HAD BEEN A RECALL FOR THE HEADLAMPS AND DAYTIME RUNNING LAMPS ON 2006 - 2007 GMC ENVOYS, THE RECALL IS FOR THE HEADLAMP MODULE. WE CONTACTED OUR LOCAL DEALER ABOUT GETTING THE RECALL REPAIRED BUT WERE TOLD OUR "VIN" WAS NOT INCLUDED IN THE RECALL. WE ALSO CONTACTED GM DIRECTLY AND SPENT OVER AN HOUR ON THE PHONE WITH THEIR CUSTOMER SUPPORT AS WELL AS A SUPERVISOR ONLY TO BE TOLD OVER AND OVER THERE WAS NOTHING THEY COULD DO TO HELP. WE TOOK OUR VEHICLE TO THE DEALER FOR REPAIR SINCE IT IS ILLEGAL TO DRIVE AT NIGHT WITHOUT HEADLIGHTS, AFTER THEY DIAGNOSED THE ISSUE WITH OUR 2007 GMC ENVOY THEY REPORTED THAT THE PROBLEM WITH OUR 2007 GMC ENVOY IS THE EXACT SAME ISSUE AS THE ONES THAT ARE COVERED IN THE RECALL, THE HEADLAMP MODULE IS BAD! WE ONCE AGAIN CALLED GM, GAVE THEM THE DIAGNOSES BUT ONCE AGAIN THEY SAID THERE IS NOTHING…”
