2008 Chevrolet Tahoe Electrical Problems

The battery energy control module GM Part # 84442220 located inside the HV battery assembly caught fire. The harness that was most affected was the battery cell voltage sense wires. The way the battery voltage sense circuit is manufactured seems dangerous as there is no fusible link between the battery cell and the module. If a short circuit occurs the full current of the cell will be induced on a very thin gauge wire going to the module which will result in a fire.

Was Delivered. Took for a test drive. Stalled at stop sign. Restarted went down the road stalled and slammed into park. Contacted company was told to take to local GMC/Chevy, (said they did a bunch of research and this part should work) basically guessing had my vehicle for 9 months replaced some sensor. Had my boyfriend Drove to red light, not even half a block, stall (stable track sensor) but lost all electric but v8 still ran took to another ( had towed) to another local shop they had for 4+ months couldn't figure out said it was running 18+ codes and would cost too much to go through. Contacted company the gentleman politely laughed and said ur kidding me right it's been years I tried to explain how long it was taking due to both repairs company had it over a year n half. No sympathy he knew exactly what he sold.

I had bought the 08 Tahoe hybrid. The day it was delivered, it stalled I called the dealership out of Minnesota and was told oh it could be this it could be that went to two local shops and a private shop all had different specifications as to what was wrong with the car due to so many codes being thrown out. You would try to take off from a stop sign or a red light car would completely lose all power, almost had multiple people slam into me because it always happened, caused so much anxiety because my only wheels to get my children around. Once again was told to take it in GM had it for over a year and could not figure the issue out. I was told by the dealer multiple times it was not their issue and they knew the position I was in an said it was inspected but refused to send me the paperwork.

The air ride control module under the spare tire in the rear of the vehicle has deteriorated and the connections melted so I had to disconnect the module I noticed smoke from underneath the rear of my vehicle I believe if I did not disconnect the module there would have been a fire i have the module that I can send pictures to you of the plug the connection and the deteriorating module these vehicles are supposed to be made to be used in the upstate weather and to leave a important piece of electrical equipment out like that is nonsense and to replace the module is approximately 500 without me going to the dealership.

THERE HAS BEEN A RECALL ON MY AIRBAGS FOR YEARS. FOR ABOUT 2 WEEKS NOW MY SERVICE AIRBAG MESSAGE HAS BEEN ON. IT CAME ON WHEN I STARTED MY CAR ONE DAY AND HAS REMAINED THERE. THE 2ND ISSUE IS SOMETHING ELECTRICAL. I CAN BE DRIVING AND I'LL LOSE ALL POWER AND LIGHTS/RADIO FOR 5-20 SECONDS AND THEN POP BACK ON. THAT HAS HAPPENED NUMEROUS TIMES. OR I'LL GET OUT OF MY CAR AND GO TO LOCK IT AND HAVE NO POWER. BOTH TIMES THAT HAS HAPPENED , I POPPED THE HOOD AND THE POWER CAME BACK ON WITHOUT ME DOING ANYTHING.

WHEN TRAVELING ABOVE 30 MPH THEN DECELERATING, ONCE THE CAR GETS TO AROUND 15-20 MPH IT JUMPS FORWARD. IT'S SIMILAR TO WHEN YOU DRIVE A STICKSHIFT AND TAKE YOUR FOOT OFF THE CLUTCH AND THE CAR JUMPS FORWARD AS IF IT MIGHT STALL. IT DOESN'T HAPPEN REGULARLY. IF I DECELERATE VERY QUICKLY, THEN IT DOES NOT DO IT. IF I DECELERATE SLOWLY THEN IT DOES NOT DO IT. IT HAS TO BE SOMEWHERE IN BETWEEN AND THE CAR IS CONFUSED BETWEEN STAYING IN GAS MODE OR SWITCHING TO HYBRID MODE AND AUTO STOP. THE CAR THEN JUMPS FORWARD WHEN CONFUSED.

I DROVE MY VEHICLE IN THE MORNING AND THEN PARKED IT FOR ABOUT 2.5 HOURS. WHEN I STARTED MY VEHICLE THE GAS GAUGE SHOWED MY CAR WAS EMPTY, EVEN THOUGH I HAD JUST RECENTLY FILLED UP AND HAD ONLY GONE ABOUT 80 MILES ON THE TANK, MY AIRBAG READINESS LIGHT STAYED ON, AND NONE OF MY GAUGES WERE FUNCTIONING. ALSO, THE LIGHT FOR THE PASSENGER AIR BAG ABOVE MY REVIEW MIRROR DIDN'T ILLUMINATE AT ALL. I DROVE IT FOR A FEW SECONDS AND TRIED TURNING IT OFF AND THEN BACK ON, BUT NOTHING CHANGED. AFTER DRIVING IT FOR A FEW MILES, I PARKED AND TURNED THE VEHICLE OFF AGAIN. WHEN I TURNED IT BACK ON, EVERYTHING BEGAN WORKING AGAIN. I BELIEVE THIS IS AN ELECTRICAL ISSUE, BUT WHEN TAKEN TO THE DEALERSHIP, I COULD NOT GET IT TO REPLICATE THE ISSUE. BESIDES THE OBVIOUS DANGER OF NOT HAVING ANY GAUGES WHILE DRIVING, MY FEAR IS THAT THE AIRBAGS WOULD NOT WORK PROPERLY IN AN ACCIDENT.

"TAKATA RECALL" MY 08 TAHOE'S INSTRUMENT PANEL AND GAUGES ARE FAILING TO WORK AT TIMES. MY SPEED GAUGE, GAS AND RPM GAUGE JUST STOPPED WORKING. THEY STARTED BACK, BUT I THINK IT'S A SAFETY ISSUE DUE TO THE FACT I WAS DRIVING IT WHEN IT HAPPENED. I AM JUST TRYING TO FIND OUT AND REPORT THE PROBLEM. THE OIL GAUGE NEVER CAME BACK ON, IS THERE ANYWAY YOU SHED SOME LIGHT ON THIS ISSUE? I WAS DRIVING ON THE HIGHWAY WHEN EVERYTHING STARTED.

TAKATA RECALL ON MY VEHICLE - WHY IS TAKING SO LONG TO REMEDY THIS RECALL? I ALSO HAVE A FEW OTHER ISSUES I WANT TO MENTION. I BOUGHT MY TAHOE IN JULY 2016, MY DASH IS CRACKING ON THE DRIVER'S SIDE AND FROM WHAT I'VE READ, THIS IS VERY COMMON AND GM IS IGNORING THE ISSUE. MY VEHICLE ALSO STARTED TAKING OFF ON ITS OWN, TOOK EXTRA PRESSURE TO STOP & RPM WOULD FLUCTUATE SPORADICALLY. AFTER CONTACTING A DEALER, I WAS TOLD THERE WAS CAMPAIGN TO REPLACE THE THROTTLE BODY SENSOR BUT IT HAD EXPIRED WHILE THE PREVIOUS OWNER HAD POSSESSION AND WAS TOLD I'D HAVE TO PAY FOR THE REPAIR AND WOULD POSSIBLY HAVE TO REPLACE THE THROTTLE BODY. AFTER REPLACING THE SENSOR, MY VEHICLE'S RPM STILL FLUCTUATES UPON STOPPING AND IDLE IS ROUGH. VERY UPSET CHEVROLET CUSTOMER NOW.

MY 2008 CHEVY TAHOE LTZ ELECTRICAL SYSTEM WOULD GO THROUGH A SERIES OF PHASES EITHER WHEN I TRY TO START IT UP DURING A COLD DAY OR WHEN I AM ON THE HIGHWAY. THIS LEADS TO MY VEHICLE EITHER NOT STARTING OR WHILE DRIVING NOT BEING ABLE TO MAINTAIN SPEED BECAUSE THE TRANSMISSION BEGIN TO SLIP. IT CAN ALSO DIE WITHOUT WARNING AND THE "CHECK ENGINE LIGHT" WOULD COME ON FOR A WHILE AND CAN DISAPPEAR AFTER STARTING UP AGAIN. I HAVE TAKEN MY VEHICLE TO THE SAME SERVICE ADVISER/MANAGER EACH TIME I EXPERIENCE THIS PROBLEM AND ALSO CALLED GMAC TO GET THEM INVOLVED TO BE TOLD THAT THEY CAN NOT DUPLICATE THIS PROBLEM. WHEN EVER THE CODES ARE PULLED, THERE COULD BE AT LEAST 7 AT A TIME. I CALLED GMAC WENT I EXPERIENCED THIS FOR THE FOURTH TIME AND MY CASE NUMBER WAS 71-1326091502 ISSUED ON 07/02/2014. TODAY MY CASE NUMBER IS [XXX] WHICH WAS ISSUED ON 11/30/2016. I HAD MANY OTHER NUMBER IN BETWEEN AND CUSTOM SERVICE PERSONNEL (GMAC) ATTEMPT TO ASSIST ME AND THE RESULTS IN THE PAST HAS BEEN THE SAME EACH TIME. HOWEVER, MY VEHICLE CONTINUE TO BE UNSAFE. I FEEL THAT NO ONE REALLY CARE BUT ARE GOING THROUGH THE PHASES TO SAY THAT THEY HAVE DONE ALL THEY CAN DO. MY VEHICLE STARTED TO GIVE ME THIS PROBLEM AT ABOUT 107,000 MILES, RIGHT AFTER MY 100,000 MILE BUMPER-TO-BUMPER WARRANTY EXPIRED WHICH COST ABOUT $2400.00. MY VEHICLE ALSO HAVE A TOTAL OF ABOUT NINE PLUS (PROBLEM MORE) MONTHS IN THE SHOP AT THE CHEVROLET DEALERSHIP OVER TIME WHERE I PURCHASED THIS VEHICLE WITH NO RESULTS AT THE END OF EACH TRIP BUT IT WAS TAKEN BACK FOR THE SAME THING EACH TIME. I FEEL AS IF EVERY ONE IS JUST COVING THEMSELVES BY MOUTH WORK WHETHER THAN BY ACTIONS. ALL I KNOW IS THAT THIS VEHICLE SEEM TO BE A "LEMON" AND NO ONE HAS THE COURAGE TO SAY SO. MY VEHICLE IS AT AL SERRA CHEVROLET NORTH, COLORADO SPRINGS, CO. 80920. THERE # IS [XXX]. MY # IS [XXX]. THANKS FOR YOUR TIME.
