2007 Acura MDX Electrical Problems

The driver's seat wiring harness on my daughter's 2007 Acura MDX has failed under normal operating conditions. The physical adjustment and movement of the driver's seat causes the factory wiring harness to over-tension and fracture internally. This has resulted in an intermittent, escalating failure of the Supplemental Restraint System (SRS), throwing diagnostic trouble code DTC 71-11 ("open circuit in the driver's seat position sensor"). This is a known manufacturer engineering defect documented under Acura Technical Service Bulletin TSB 11-023. This defect poses an immediate safety hazard because the vehicle's computer automatically disables the driver's side airbag safety deployment when the circuit loses connection. The manufacturer is currently refusing to cover the repair due to the age of the vehicle, despite it being a critical safety-restraint system failure that leaves the driver unprotected in a collision. (The exact date of first onset is estimated, as this safety defect is an ongoing, intermittent electrical failure that began several months ago but only recently became more frequent. We also were originally unaware that the airbag warning light coming on meant the airbags were disabled, or we would have brought the car in sooner.)

OVER THE PAST TWO YEARS HAVE HAD TO INEXPLICABLY JUMP MDX WHEN IT FAILS TO START, USUALLY AFTER SITTING OVER NIGHT. (CONFIRMED NO AUXILIARY POWER LEFT ON.) WILL BE FINE FOR A PERIOD OF TIME, AND SYMPTOMS REAPPEAR. HAVE NOW CHANGED BATTERY TWICE IN PAST YEAR. FOUR MONTHS AFTER MOST RECENT BATTERY CHANGE, BATTERY WAS DEAD AGAIN. THIS TIME AFTER JUMPED THE CAR THREW SOME ADDITIONAL WARNING LIGHTS AROUND CHARGING SYSTEM. AFTER TRYING TO RETURN TO THE PARKING SPACE, THE CAR STARTED WAS NOT DRIVING PROPERLY, SEEMS TO BE ELECTRICAL. AFTER READING FORUMS ONLINE MY SYMPTOMS MATCH VERY CLOSELY TO OTHERS THAT HAVE A HANDSFREELINK ISSUE ON THIS MODEL MDX. (PARASITIC POWER DRAW.) CONTACTING ACURA TODAY, AS THIS TIME THE CAR IS NOT DRIVE-ABLE.

WHILE DRIVING, THE CAR WILL FREQUENTLY LOSE ELECTRICAL POWER. DASH INDICATOR LIGHTS COME ON, THE RADIO SHUTS OFF AND SOMETIME I'LL HAVE TO RESET THE RADIO AND NAVIGATION CODES. WHILE AT A STOP LIGHT, SOMETIMES DEPRESSING THE GAS PEDAL DOES NOTHING AND THEN SUDDENLY IT WILL BEGIN TO MOVE. I'M VERY CONCERN THE UNPREDICTABLE NATURE OF THE PROBLEM WILL CAUSE A WRECK IF I LOSE ENGINE POWER, ESPECIALLY IN A CURVE.

I OWN A 2007 ACURA MDX WHICH HAS HAD A NUMBER OF INTERMITTENT ELECTRICAL PROBLEMS OVER THE YEARS. I HAD TO REPLACE THE HANDSFREE LINK MODULE A FEW YEARS AGO AT THE DEALER. THE YELLOW CHECK OIL LEVEL LIGHT HAS COME ON FOR NO REASON FOR YEARS. IT GOES ON FOR A SECOND THEN OFF. A FEW MONTHS AGO THE ENTIRE ELECTRICAL SYSTEM 'FRIED' AND I HAD TO BUY A NEW BATTERY AND NEW ALTERNATOR. RECENTLY I HEAR A BUZZING SOUND WHEN I USE THE TURN SIGNALS AND THE HAZARDS DO NOT WORK AT ALL. LAST NIGHT THE CAR DIED ON THE INTERSTATE- THE INSTRUMENT PANEL WENT DARK, THE ENGINE WOULD NOT ACCELERATE, AND I WAS LUCKY TO BE ABLE TO GET ONTO THE SHOULDER. I TURNED OFF THE CAR AND THEN STARTED IT AGAIN. WHEN IT WORKS THERE IS NO PROBLEM WITH THE OPERATION BUT THIS CAR IS NOW UNRELIABLE AND DANGEROUS. I SEE THERE HAVE BEEN OVER 40 COMPLAINTS FOR THE SAME THING NOTED ON CARCOMPLAINTS.COM REFERRING TO THE NHTSA WEBSITE, ABOUT THE CAR DYING FOR NO REASON WHILE IN MOTION AND THAT NO ACURA DEALER SEEMS ABLE TO FIX IT AND ACURA REFUSES TO ACKNOWLEDGE THE PROBLEM OR DO A RECALL THE CAR IS NOW AT MY MECHANIC TO SEE IF HE CAN FIND OUT WHAT IS WRONG BUT ALL THE COMMENTS I SAW ON CARCOMPLAINTS.COM INDICATE THERE HAS NOT YET BEEN A DEFINITIVE DIAGNOSIS MADE BY ACURA OR ANYONE ELSE, AND THERE IS NO ACTIVE RECALL EITHER THIS IS EXTREMELY DANGEROUS AS THE OTHER COMPLAINTS ALSO INDICATE THAT THE DOORS AND WINDOWS DO NOT OPERATE WHEN THE CAR STALLS OUT AND OCCUPANTS CAN BE TRAPPED INSIDE THE CAR

I'VE EXPERIENCED SEVERAL ELECTRICAL ISSUES ELECTRICAL WITH MY VEHICLE THE MOST TROUBLING WAS THE VEHICLE COMPLETELY SHUT OFF ON THE HIGHWAY THEN IMMEDIATELY RESTARTED!!!! IN ADDITION TO THIS, THE NEXT ISSUE IS BATTERY PERFORMANCE. THE BATTERY IS CONSTANTLY DRAINED. IN THE 11 YEARS THAT I OWNED THE VEHICLE, THE BATTERY HAS BEEN REPLACED 4 TIMES. (I INITIALLY THOUGHT THIS WAS ASSOCIATED WITH MY BLUETOOTH BEING CONNECTED BUT I'VE DISCONNECTED THIS MANY YEARS AGO AND THE ISSUES STILL PERSIST. I WAS STRAINED ON WINTER BECAUSE THE BATTERY DRAINED AND WAS STUCK AT THE AIRPORT FOR 3 1/2 HOURS WAITING FOR AAA. LASTLY, I TURNED MY CAR ON THIS PAST SUNDAY WHEN MY MIL DISPLAY "CHECK TRANSMISSION." I BROUGHT THE CAR TO ACURA FOR SERVICE AND THEY HAVE INFORMED ME THAT THE GEAR POSITION SENSOR MUST BE REPLACED. THIS IS ANOTHER ELECTRICAL CIRCUIT PROBLEM OF A MECHANICAL PROBLEM WITH THE TRANSMISSION. TOO MANY ELECTRICAL ISSUES!!!

I BOUGHT THIS CAR ON MOTHER'S DAY 2017. DURING THE FOLLOWING MONTH I HAD THE CHECK ENGINE LIGHT ON NON-STOP, I STARTED RECEIVING ERROR CODES, THEN ON THE WAY TO THE AIRPORT (ONE THE INTERSTATE), THE CAR LITERALLY TURNED OFF. WE ROLLED TO THE AIRPORT WITH NO ELECTRICAL SYSTEM AT ALL, THEN THE CAR FINALLY DIED, THANK GOODNESS WE GOT OUT BECAUSE FOR A FEW MINUTES WE WERE LOCKED IN THE CAR! WE REPLACED THE ALTERNATOR, THE BATTERY, 3 OF THE 4 (O2) OXYGEN SENSORS, NOW THE TRANSMISSION LIGHT, THE CHECK ENGINE LIGHT AND THE CHECK STARTING SYSTEM LIGHT ARE ON. TODAY, THE CAR DIDN'T START TWICE AND I HONESTLY FELT AT RISK JUST TRYING TO DRIVE HOME TODAY. SO ALL THIS HAS BEEN FROM MOTHER'S DAY 2017 TO NOW! SEPTEMBER 20, 2018. THE LIGHTS AND CODES DON'T STOP ON THIS CAR!

HAD A BIG RAIN STORM THE OTHER DAY. GOT INTO MY CAR AFTER IT BEING PARKED AT WORK ALL DAY AND FOUND IT WAS LEAKING FROM "C" PILLAR. TURNS OUT, SUNROOF DECIDED TO FLIP UP ON ITS OWN DURING THE DAY WITH THE CAR PARKED AND OFF. TOOK CAR TO MY LOCAL SHOP WHO HAS BEEN FAMILIAR WITH ACURA ELECTRICAL PROBLEMS. I TOLD HIM TO DISCONNECT THE WIRES TO THE SUNROOF FUNCTION COMPLETELY. I DONT NEED TO USE THE SUNROOF OR HAVE IT DECIDE TO OPEN ON ITS OWN AGAIN. THIS PROBLEM COULD HAVE CAUSED EVEN MORE SERIOUS ELECTRICAL PROBLEMS, BUT LUCKILY WATER DID NOT PENETRATE TO THE OTHER ELECTRICAL SYSTEMS. THIS IS THE THIRD MAJOR ELECTRICAL PROBLEM I HAVE HAD WITH THIS VEHICLE. THERE ARE SERIOUS ELECTRICAL PROBLEMS WITH THE MDX AND ACRUA/HONDA REFUSES TO ISSUE ANY RECALL OR EVEN ADDRESS THE PROBLEMS, WHICH ARE PROMINENT IN THIS VEHICLE

CAME OUT TO A DEAD BATTERY AFTER REPLACING BATTERY JUST A FEW MONTHS EARLIER. AFTER ALREADY GOING THROUGH THE ELECTRICAL PROBLEM OF THE DEFECTIVE BLUE TOOTH, KNEW IT WAS ANOTHER ELECTRICAL PROBLEM. TOOK CAR TO MY LOCAL SHOP WHERE HE DIAGNOSED ANOTHER ELECTRICAL PROBLEM, THIS TIME WITH THE AIR CONDITIONER RELAY/COMPRESSOR SWITCH. I DO NOT WANT TO BE WITHOUT AIR CONDITIONING, SO HAD THEM FIX THE PROBLEM. THIS IS THE SECOND ELECTRICAL PROBLEM WITH THE 10 YEAR OLD MDX WITH ONLY 90,000 MILES. THIS VEHICLE HAS SERIOUS ELECTRICAL PROBLEMS AND THEY ARE BEING IGNORED BY HONDA MOTORS. I HAVE READ MANY INSTANCES ONLINE OF PEOPLE WHO HAD THIS SAME VEHICLE AND THE CARS HAVE CAUGHT ON FIRE FROM THESE VARIOUS ELECTRICAL PROBLEMS

THIS IS A LIFE TREATING INCIDENT AND NEEDS AN IMMEDIATE RECALL. THERE ARE NUMEROUS ONLINE COMPLAINTS ABOUT THIS ISSUE, SO WHY ISN'T THERE A RECALL.

HAVING ISSUES WITH THE DRAINAGE OF BATTERY. THREE IN ONE YEAR. THE CULPRIT WAS THE HANDS FREE LINK AND XM RADIO. THE BLUETOOTH FEATURES IN THIS CAR HAS CAUSED IT TO SHUTDOWN COMPLETELY SEVERAL TIMES OR NOT START UP. AFTER SEARCHING ONLINE, THIS HAS BEEN THE COMPLAINT BY THOUSANDS OF OTHER ACURA MDX 2007. THIS IS DANGEROUS AND MAY CAUSE CAR ACCIDENTS. THIS IS TOO COMMON AN ISSUE TO NOT RECALL THESE PARTS.

THIS IS THE THIRD TIME THE ELECTRICAL SYSTEM HAS FAILED CAUSED BY "BATTERY DRAINAGE". LOCAL REPAIR SHOPS DO NOT KNOW HOW TO FIX PROBLEMS, BUT DEALER'S AND HONDA MECHANICS ARE VERY FAMILIAR WITH THIS HORRIBLE PROBLEM. EVERYONE FIXING THE PROBLEM KNOWS VERY WELL THIS SHOULD BE "A RECALL" MATTER, AND CREATES A GREAT ROAD HAZARD AS WELL ARE GARAGE FIRES AND LOSS OF LIFE. THE THINGS INVOLVED ARE "BLUE TOOTH" MODULAR, AIR CONDITIONER CLUTCH RELAY, FUSES. REGARDING THE BLUE TOOTH, THIS MODULAR GETS VERY VERY HOT, AND COULD CAUSE A FIRE!! WHEN THE BATTERY FAILS TO CHARGE WHILE DRIVING TO GET SAFELY OFF THE HIGHWAY IS VERY DANGEROUS, MUCH WORST AT DARKNESS!! HONDA NEEDS TO GET THEIR ACT TOGETHER AND RECALL AND FIX THESE PROBLEMS NOW. MY EXPERIENCE HAPPENED WITH THE CAR IN MOTION, AND ALL INDICATORS FLASHING, REAR AXLE NOISES, HEAT INSIDE CAR, LOSS OF POWER, AND VEHICLE IN "KIND OF, A LIMPING MODE". VERY SCARY AND DANGEROUS OCCURRENCE. WE ARE THE ORIGINAL OWNER OF THE CAR, NOW WITH 140,000 MILES, AND ALWAYS SERVICED EVERY 3-5,000 MILES. WE HAVE TAKEN PRIDE IN THIS VEHICLE, UNTIL THIS "BATTERY DRAINAGE" PROBLEM, NOW IS EFFECTING OUR THOUGHTS ABOUT HONDA MOTORS.
