Gmc
Envoy

While stopped at a light engine turned itself off with every warning light went off. Glad this didn’t happen with I was driving at highway speed as I lost all systems.

The contact owns a 2007 GMC Envoy. The contact stated that the power switch used to adjust the front driver seat had failed to operate as needed. The contact stated that the power switch had been replaced a total of three times within a two-month time frame. Recently, the power switch had failed for a fourth time and as the contact went to replace the fuse, the fuse box was so hot that it burned the contact's right hand and left a blister. The contact did not seek any medical attention for the injury. Upon investigation, the contact discovered NHTSA Campaign Number: 12V406000 (Electrical System, Visibility) which was linked to the failure. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was unknown.

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. THEIR OPERATION SHOULD NOT RELY ON AN ELECTRONIC SUB-SYSTEM WHOSE FAILURE MODE PREVENTS THE LOW BEAM HEADLIGHTS FROM WORKING. THIS SYSTEM WAS DESIGNED THE 'EASY' WAY WITHOUT REGARDS TO VEHICLE SAFETY...NAMELY THAT WHEN THE DASHBOARD LIGHT SWITCH IS IN THE ON POSITION, THE HEADLIGHTS ARE ENABLED BY A SIGNAL DIRECTLY FROM THAT SWITCH. WITHOUT AN AFFIRMATIVE ENABLING SIGNAL FROM THE MANUAL DASHBOARD LIGHT SWITCH, THE SYSTEM AND VEHICLE OPERATOR IS AT THE MERCY OF THE BCM, WHICH COULD FAIL AT NIGHT OR ON THE WEEKEND (WHEN A REPAIR SHOP IS UNAVAILABLE) RENDERING THE VEHICLE DANGEROUS OR UN-DRIVEABLE.

THE CHECK STABILITRAK LIGHT KEEPS COMING ON CAUSING THE CHECK ENGINE LIGHT TO COME ON CAUSING ENVOY TO LOOSE POWER. WHILE DRIVING. SECOND ISSUE IS THE DRIVERS DOOR STARTED ACTING UP DIDN'T WANT TO GO UP AND NOW WILL NOT DO ANYTHING CAUSING THE ENTIRE SYSTEM TO NOT LOCK AND WORK THE MIRRORS OR ANYTHING ELECTRICAL FROM THE DOOR PANEL.

I ROLLED MY DRIVER'S WINDOW DOWN THIS MORNING AND TRIED TO ROLL IT BACK UP AND IT ACTED LIKE IT DIDN'T WANT TO GO BACK UP. IT STARTED TO GO UP AND THEN IT STOPPED AFTER A FEW SECONDS AND I TRIED HITTING THE BUTTON AGAIN AND NOTHING HAPPENED. THEN I HIT THE BUTTON AGAIN AND IT STARTED TO GO UP BUT VERY SLOWLY THEN IT STOPPED AGAIN. I DID THIS FOR A BIT UNTIL THE WINDOW WENT ALL THE WAY UP. THIS HAS HAPPENED A COUPLE OTHER TIMES ALSO. TODAY WAS THE 1ST TIME THAT IT REALLY DID NOT WANT TO GO BACK UP. THE VEHICLE WAS STOPPED IN A PARKING LOT AT THAT TIME.
