2007 GMC Envoy Electrical System Problems

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.

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.

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.

THE FUEL GAUGE SHOWS EMPTY WHEN THERE IS FUEL IN VEHICLE

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.

DRIVER'S DOOR MASTER POWER WINDOW SWITCH MODULE WAS WORKING INTERMITTENTLY AND NOW IS INOPERABLE CAUSING ME TO BECOME LOCKED OUT OF MY VEHICLE. THERE WAS A SIMILAR RECALL TO THE SAME YEAR ENVOYS IN 2014, BUT WHEN I CHECKED THE VIN MINE WAS NOT INCLUDED IN THE RECALL, BUT AM HAVING THE SAME ISSUE

HEADLAMPS TURN OFF WIN DRIVING IT HAS DONE THIS IN THE CITY AND ON THE HIGHWAY I HAVE TO PULL OVER AND TURN THE KEY OFF AND WIN I RESTART IT ITS FINE. THIS OCCURRED SUDDENLY AND INTERMITTENTLY STILL NOT DETERMINED WHY. I DID FIND A RECALL ON THESE VEHICLES BUT MY VIN IS NOT LISTED THIS IS NOT SAFE AND GM SHOULD PAY FORE IT NOT ME THANK YOU. 2007 GMC ENVOY

LOW BEAM HEADLIGHTS FAIL INTERMITTENTLY WHILE VEHICLE IS IN OPERATION. VIN NOT ELIGIBLE FOR RECALL UNDER CURRENT HEADLIGHT PROBE GAUGES HAVE FAILED STARTING WITH FUEL GAUGE.

TL* THE CONTACT OWNS A 2007 GMC ENVOY. WHILE DRIVING 40 MPH, THE HEADLIGHTS FAILED TO WORK. AFTER A FEW MINUTES, THE HEADLIGHTS AUTOMATICALLY TURNED ON AND WORKED NORMALLY. THE FAILURE OCCURRED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO THE DEALER (WILLISTON MOTORS, 1801 2ND AVE W, WILLISTON, ND 58801) WHERE IT WAS DIAGNOSED THAT THE FUSE BOX NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED AT 888-988-7267 AND STATED THAT THE VIN WAS NOT INCLUDED IN A RECALL. THE MANUFACTURER PROVIDED CASE NUMBER: 8-3395918942. THE APPROXIMATE FAILURE MILEAGE WAS 137,000.

HEADLIGHTS CONTINUE TO GO OUT WHILE DRIVING CITY STREETS AND HIGHWAY. WINDOWS HESITATE TO GO UP AND MAKE A GRINDING NOISE. AT TIMES SMELLS LIKE SMOKE AND THEN DISSIPATES.

FRONT HEADLIGHTS OUT. ALL OTHER LIGHTS WORKING.

BOTH HEADLIGHTS ABRUPTLY STOPPED WORKING. LOW-BEAM HEADLAMPS AND DAYTIME RUNNING LIGHTS DID NOT FUNCTION. WHILE RESEARCHING POSSIBLE CAUSES AND SOLUTIONS, I DISCOVERED A GM SAFETY RECALL (NO. 14291) WHICH PRECISELY DESCRIBED THE PROBLEM. UPON PRESENTING THE VEHICLE FOR REPAIRS, THE SERVICING DEALER INDICATED THE RECALL DID NOT COVER MY VEHICLE. GIVEN NO OTHER VIABLE OPTIONS, I APPROVED THE REPAIR, THE COST OF WHICH WAS $278. I CONTEND THAT MY VEHICLE SHOULD HAVE BEEN COVERED UNDER SAID RECALL AND AM ASKING NHTSA TO REVIEW THIS MATTER.

TL* THE CONTACT OWNS A 2007 GMC ENVOY. WHILE DRIVING APPROXIMATELY 65 MPH, THERE WAS A SUDDEN LOSS OF POWER AND A WARNING INDICATOR ILLUMINATED FOR LIMP MODE. THE VEHICLE DRASTICALLY REDUCED SPEED TO LESS THAN 35 MPH. THE CONTACT HAD TO SLOWLY DRIVE IN THE EMERGENCY LANE. THE VEHICLE WAS TURNED OFF AND BACK ON, BUT THE LIMP MODE FAILURE CONTINUED. THE CONTACT WAS UNABLE TO DRIVE OVER 35 MPH. THE VEHICLE WAS TAKEN TO A DEALER WHO KEPT THE VEHICLE FOR LONGER THAN TWO WEEKS. THE DEALER CLEARED MULTIPLE CODES, BUT WAS UNABLE TO PROVIDE A SOLUTION. IN ADDITION, MONTHS LATER, THE ENGINE LOCKED AND FAILED TO FUNCTION. THE VEHICLE WAS UNABLE TO BE DRIVEN. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURES. THE VIN AND FAILURE MILEAGE WERE NOT AVAILABLE.

TL* THE CONTACT OWNS A 2007 GMC ENVOY. THE CONTACT STATED THAT THE LOW BEAMS FAILED TO ILLUMINATE. THE CONTACT WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBERS: 13V248000 (ELECTRICAL SYSTEM AND VISIBILITY), 12V406000 (ELECTRICAL SYSTEM AND VISIBILITY) AND 15V519000 (EXTERIOR LIGHTING). THE DEALER ALSO REPLACED THE WINDOW REGULATOR DUE TO THE WINDOWS FAILING TO GO UP AND DOWN RANDOMLY. THE VEHICLE WAS TO BE TAKEN BACK TO THE DEALER FOR FURTHER DIAGNOSTIC TESTING. THE FAILURE MILEAGE WAS NOT AVAILABLE.

BATTERY DYING EVERYDAY. PARASITIC DRAW FROM THE POWER SEAT.

FOR MANY, MANY, MONTHS MY LOW BEAM LIGHTS HAVE BEEN GOING OUT WHILE DRIVING. ALL OTHER LIGHTS INCLUDING THE HIGH BEAMS WILL WORK. IT IS VERY UNSAFE TO BE DRIVING AT NIGHT AND HAVE YOUR LIGHTS GO OUT. I HAVE TAKEN THE VEHICLE TO SEVERAL DIFFERENT AUTO SHOPS, BUT THEY CAN'T FIND ANYTHING WRONG. I HAVE SEEN MANY COMPLAINTS ABOUT THIS ISSUE, SO I KNOW IT IS THE VEHICLE. GMC NEEDS TO DO THE RIGHT THING AND FIX THIS PROBLEM. IF GMC WON'T DO IT ON THEIR OWN, THE NHTSA NEEDS TO GET INVOLVED AND GET GMC TO RECALL THESE VEHICLES AND FIX THIS PROBLEM. THIS IS A VERY SERIOUS SAFETY ISSUE.

TAKATA RECALL WAS DRIVING HOME AT NIGHT LOST THE LOW BEAMS THEY WOULD KEEP GOING OFF HAVING ME WITH NO LIGHTS AT ALL THE HIGH BEAMS WOULD WORK BUT NO LOW BEAMS AT ALL DRIVING WITH HIGH BEAMS ON IS NOT SAFE AND CAN GET PULLED OVER FOR THIS I HAVE HAD THIS BEFORE AND TURNED IT IN AND NOTHING I WOULD LIKE SOMTHING DONE ABOUT THIS IT IS SAFTY ISSUE AND SHOULD BE TAKEN CARE OF BY THE MANUFACTURES OF THIS CAR OR SUV

THE RECALL DETAILS WERE UNKNOWN. THE FAILURE MILEAGE WAS 120,000.
