2009 Honda Odyssey Electrical Problems

Your windshield wipers, key fob, sliding doors, and turn signal lights stopped working all at the same time—first in December 2023 and again in January 2024. The problem happened without warning while you were driving, and during the second occurrence it was raining, making it unsafe because you couldn't see and your lights weren't working. This issue may require diagnosis of the electrical system, potentially involving a faulty relay, fuse, or body control module that controls multiple systems.

Your driver's side door started making a grinding noise and then fell off its track when you tried to close it, nearly catching your child in the process. The door sustained significant damage and is no longer functioning properly. The issue likely involves the door track mechanism or rollers that guide the door, which may need realignment or replacement.

RIGHT REAR SLIDING DOOR HAS OPENED WHILE CAR IS MOVING. SUSPECT IT IS THE CAUSE OF THE BATTERY BEING DRAINED TWICE IN THE LAST FEW DAYS WHEN CAR WAS NOT DRIVEN DURING 48 HOUR PERIOD. THE DOOR WILL NOT OPEN ELECTRONICALLY NOW. IT HAS TO BE FORCED OPEN MANUALLY.

FRONT PASSENGER DOORS DOESN'T OPEN FROM INSIDE OF THE CAR UNLESS UNLOCK/LOCK/UNLOCK IS PRESSED FROM DRIVER SIDE. THIS HAS BEEN OCCURRING FROM 2010. TALKED TO DEALER BUT THEY CAN'T FIND ANYTHING WRONG. AND I DIDN'T WANT TO PAY FOR INVESTIGATION. THEY SAID IT HAS TO BE FAIL AND REMAINED FAILURE FOR THEM TO SEE AND INVESTIGATE.

THE CAR WAS OFF AND THE DAYTIME RUNNING LIGHTS STARTED COMING ON WHICH WAS DRAINING THE BATTERY. DIFFERENT LIGHTS STARTED TO ILLUMINATE ON THE DASHBOARD WITH THE CAR OFF. THE VSA LIGHT CAME ON. TOOK IT TO A COUPLE OF DIFFERENT SHOPS TO GET IT DIAGNOSED AND THEY DETERMINED THAT THE CABIN WIRE HARNESS IS CORRODED DUE TO A LEAK IN THE ROOF RUN CHANNELS AND OR WINDSHIELD. THE UNDER THE DASH FUSE BOX IS ALSO SHOWING CORROSION AND NEEDS REPLACING. THE VEHICLE ONLY HAS 64000 MILES AND THE REPAIR IS QUOTED AT $3465. A VERY COSTLY REPAIR WHICH SEEMS IS DUE TO FAULTY MANUFACTURING OR ASSEMBLY.

ALL WINDOWS EXCEPT THE DRIVER'S STOPPED FUNCTIONING. THIS PROBLEM HAPPENS WITH ENGINE ON OR OFF. THIS PROBLEM HAPPENS WHEN STATIONARY OR MOVING. TRIED THE CHILD SAFETY BUTTON, BUT STILL A PROBLEM. YOU CAN HEAR THEM CLICK, BUT THE MOTORS WILL NOT ENGAGE. IT APPEARS THERE IS A FAULTY MASTER SWITCH. OTHERS HAVE THE SAME ISSUE HERE: HTTPS://WWW.CARGURUS.COM/CARS/DISCUSSION-C3836_DS530625

UNABLE TO LIFT UP PASSENGER SIDE WINDOW (FRONT AND REAR) ONCE WINDOW IS DOWN MAINLY IN COLD WEATHER. ALSO TIME TO TIME, UNABLE TO OPEN FRONT PASSENGER SIDE DOOR FROM INSIDE. I HAVE TO OPEN AND CLOSE THE DOOR USING DRIVE SIDE BUTTON FROM INSIDE THE VEHICLE, OR USE REMOTE CONTROL TO PERFORM LOCK/UNLOCK FUNCTION. FOR WINDOW OPERATION IT DOESN'T MATTER IF THE VEHICLE IS MOVING OR NOT MOVING. FOR LOCK OPERATION VEHICLE IS NOT MOVING. FOR BOTH OPERATION VEHICLE ENGINE COULD BE ON. THIS PROBLEM HAS BEEN THERE SINCE THE DAY ONE I BOUGHT THE VEHICLE. DEALERSHIP WAS INFORMED BUT THEY WERE UNABLE TO FIND THE PROBLEM BECAUSE MOST OF THE TIME PROBLEM RECOVERS BY THE TIME WE REACH DEALERSHIP (30 MINUTES LATER)

TOOK THE CAR TO THE HONDA DEALERSHIP FOR EMISSIONS CHECK LIGHT. DIAGNOSED AS "NOX SENSOR WIRING HARNESS CHEWED BY MOUSE" PER HONDA DEALERSHIP. THERE IS NO EVIDENCE OF RODENT DAMAGE OR PRESENCE ELSEWHERE IN THE VEHICLE. THE HONDA DEALERSHIP DID NOT PROVIDE ME THE PICTURES OR THE DAMAGED PART SAYING THAT IT WAS THROWN IN THE TRASH. THE WIRING WAS APPARENTLY COVERED BY HONDA RODENT DETERRENT TAPE. I HAVE CONTACTED ACURA/HONDA DEALERSHIPS, THEIR EXTENDED WARRANTY CUSTOMER SERVICE AND ALSO THE RESPECTIVE ACURA/HONDA MANUFACTURER CUSTOMER SERVICE. THE SAME THING HAPPENED TO MY OTHER CAR (ACURA MDX 2009) WITHIN A SPAN OF ONE WEEK WITH EXACTLY SIMILAR PRESENTATION. WHEN I REQUESTED INFORMATION FROM THE ABOVE SOURCES, I WAS TOLD THAT THIS WAS CONFIDENTIAL INFORMATION AND IS NOT AVAILABLE FOR CUSTOMERS AND THAT IS IT IS A RARE EVENT AND NOT RELATED TO MANUFACTURING DEFECTS AND ALSO THERE WAS NO DEFINITIVE TREND IN ACURA/HONDA(SAME COMPANY) NOX SENSOR WIRING HARNESS BEING CHEWED BY RODENTS AND HAVE REFUSED TO COVER IT UNDER EXTENDED WARRANTY PROGRAM TO WHICH I HAVE SUBSCRIBED/PURCHASED. I HAVE ANOTHER ENTRY REGARDING THE OTHER VEHICLE AT THE NHTSA.GOV WEBSITE. *TR

WHILE DRIVING ON THE HIGHWAY AT APPROXIMATELY 70 MPH MY WIFE'S 2009 HONDA ODYSSEY BEGAN TO SHAKE AS I STEPPED ON THE GAS THE ENGINE LIGHT CAME ON AND THE VEHICLE LOST ENGINE POWER AND I HAD TO MANUALLY STEER TO THE SIDE OF THE HIGHWAY.. UPON OPENING THE HOOD I COULD SMELL THAT SOMETHING WAS BURNING. THE VEHICLE WAS TOWED 79 MILES TO MY MECHANIC. I WAS INFORMED THAT A SPARK PLUG BLEW OUT COMPLETELY AND A PORTION OF THAT PLUG ENTERED THE CYLINDER AND DAMAGED THE ENGINE. THE ENTIRE THREADING OF THE SPARK PLUG WAS DAMAGED AND MELTED INTO THE ENGINE. I WAS INFORMED THAT THE ENTIRE ENGINE NEEDS TO BE REPLACED. *TR

WHEN USING THE VAN ON SEVERAL OCCASIONS IN THE CITY STREETS. WHILE RAINING AND AFTER IT HAS RAINED, THE VAN THE BATTERY LIGHT HAS TURNED ON THE HAS VAN TURNED OFF. I HAVE TAKEN THE VAN TWICE TO GET THIS CHECKED OUT AND THEY HAVE TOLD ME IT DOES NOT HAVE ANYTHING. I TOOK IT ON SEPTEMBER 2014 AND AGAIN IN NOVEMBER 2014. WHILE USING THE VAN IN THE RAIN I HAVE COME TO A STOP SIGN TO TURN AND GOING IN TO TRAFFIC THE VAN IT TURNS OFF . THIS HAPPENED AGAIN THIS LAST WEEK ON NOV. 25 2014. BECAUSE OF THIS I AM SCARED OF USING THE VAN WHEN IT RAINS. MY WIFE IS ALWAYS USING THE VAN WITH ARE GRANDCHILDREN. *TR

THE CAR'S AC SYSTEM IS MALFUNCTIONING. THE AIR CONDITIONING WILL SOMETIMES BLOW COLD AIR AND OTHER TIMES BLOW WARM AIR WHEN ON THE LOWEST TEMPERATURE SETTING WITH THE AC ON. ALSO, IT WILL SOMETIMES BLOW HOT AIR ON THE DRIVER'S SIDE AND COLD AIR ON THE PASSENGER'S SIDE. WE'VE TAKEN THE VEHICLE TO TWO DIFFERENT SHOPS (NON-HONDA) AND BOTH HAVE CONFIRMED THE UNIT IS COMPLETELY CHARGED AND CAN NOT DETERMINE WHAT THE ISSUE IS. A SEARCH ON THE ISSUE SEEMS THAT SEVERAL OTHER OWNERS ARE EXPERIENCING THE SAME ISSUE WITH THEIR VEHICLES. *JS

WE OWNED A 2009 HONDA ODYSSEY . THIS VEHICLE HAS BEEN MAINTAINED WELL FOR YEARS AT HONDA DEALERSHIPS. I HAVE PURCHASED EXTENDED WARRANTY FOR 120K MILES ON THIS VEHICLE SINCE WE WERE PLANNING TO USE THIS VEHICLE FOR A LONG TIME. LAST TIME I HAD ANY WORK DONE ON THIS CAR WAS IN 12/31/13 AT A HONDA DEALERSHIP. IT WAS A MAJOR SERVICE. WE DID NOT HAVE ANY ISSUE WITH THE VEHICLE UNTIL THE EVENT THAT LED TO THE FIRE ON THE VEHICLE. AS MY WIFE WAS DRIVING HER ODYSSEY ON I-280/CA-85, SHE STATED THAT ALL THE WARNING LIGHTS/GAUGE ON THE DASHBOARD CAME ON. AT THE SAME TIME SHE REALIZED THAT CAR WOULD NOT ACCELERATE. WHEN SHE INSTINCTIVELY LOOKED AT THE TEMPERATURE GAUGE ON THE DASHBOARD, IT WAS NORMAL (ABOUT HALFWAY UP) DUE TO THIS SYMPTOM, SHE WAS FORCED TO PARK THE CAR TO THE SIDE OF THE HIGHWAY. AT THIS POINT, MY WIFE ORDERED BOTH OF MY KIDS IN THE CAR TO EXIT THE VEHICLE AND MOVE TO THE SIDE OF THE ROAD ON THE HIGHWAY. SHE DID EXIT THE VEHICLE AS WELL. AS THE SMOKE FROM THE CAR CHANGED FROM WHITE TO BLACK, SHE CALLED 911. AS SHE WAITED FOR THE FIRE ENGINE TO ARRIVE (WHICH ACCORDING TO HER TOOK 10 MINUTES), WHOLE CAR WAS ENGULFED IN FIRE FROM BUMPER TO BUMPER. WHEN I ARRIVED AT THE SCENE, THERE WERE POLICE CARS AND FIRE TRUCKS. TWO LANES ON CA-85 WAS CLOSED. MY WIFE AND MY KIDS WERE IN SHOCK AND WERE CRYING. I TOOK MY WIFE AND KIDS HOME AFTERWARDS. WE LOST PERSONAL ITEMS THAT WERE LEFT IN THE CAR SUCH AS GLASSES, JACKETS, AND OTHER ITEMS. SANTA CLARA COUNTY FIRE DEPARTMENT TOLD ME THAT THEY WILL BE OPENING UP A CASE. I CAN NOT STOP TO THINK ABOUT WHAT IS THE REASON WHY THIS FIRE OCCURRED ON THE VEHICLE. WE DID NOT HAVE ANY INDICATION THAT THIS WOULD OCCUR EXCEPT FOR THE LAST MINUTE DASHBOARD INDICATION. CONSIDERING THE VEHICLE WAS BOUGHT/SERVICED AT HONDA, WE ARE BEGINNING TO LOSE FAITH ON HONDA VEHICLE/SERVICE IN GENERAL. *TR

BATTERY WENT DEAD AT IDLE WITH AC ON. WHILE STARTING HE ENGINE, A ABNORMAL SOUND WAS MAKE BY WHEN TRYING TO TURN THE ENGINE OVER AND THE AC FREON LEAKED OUT, DOORS WOULD NOT OPEN. AFTER SHUT DOWN, THE CAR WOULD NOT START AND DOORS WOULD NOT OPEN. *TR

TL* THE CONTACT OWNS A 2009 HONDA ODYSSEY. THE CONTACT STATED THAT AFTER TURNING THE KEY HALFWAY, THE CONTACT SUDDENLY HEARD A SPUTTERING NOISE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE FAILURE COULD NOT BE REPLICATED. THE VEHICLE WAS NOT REPAIRED. APPROXIMATELY A FEW WEEKS THE LATER, THE FAILURE WORSENED. THE MANUFACTURER WAS CONTACTED AND OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS UNKNOWN. THE CURRENT MILEAGE WAS APPROXIMATELY 15,797. THE VIN WAS UNAVAILABLE.

THE AIR CONDITIONING (A/C) CONTROL RELAY ON MY 2009 HONDA ODYSSEY FAILED LESS THAN 3 YEARS AFTER PURCHASE, CAUSING INTERMITTENT ELECTRICAL PROBLEMS THAT WOULD PREVENT THE CAR FROM STARTING. WHEN THE CAR'S IGNITION SWITCH IS PLACED IN THE "ACCESSORY I" POSITION, ONLY THE AUDIO SYSTEM AND ACCESSORY POWER SOCKETS SHOULD BE ENGAGED AND ABLE TO OPERATE. MY A/C CONTROL RELAY FAILED IN THE CLOSED POSITION, CAUSING THE A/C COMPRESSOR IN MY CAR TO RUN CONTINUOUSLY, EVEN WHEN THE IGNITION SWITCH WAS IN THE ACCESSORY I POSITION. THE END RESULT WAS WHENEVER I LEFT THE IGNITION SWITCH IN THE ACCESSORY POSITION FOR MORE THEN A COUPLE MINUTES, THE RUNNING A/C COMPRESSOR WOULD VERY QUICKLY DRAIN THE BATTERY, LEAVING THE CAR UNABLE TO START. PLACING THE IGNITION SWITCH IN THE ACCESSORY POSITION FOR A MATTER OF MINUTES SHOULD NOT RESULT IN A PERSON BEING STRANDED !!! THE PART NUMBER FOR THE A/C COMPRESSOR RELAY ON MY 2009 ODYSSEY IS OMRON G8HL-H71. HONDA'S CORRESPONDING PART NUMBER IS FOR THIS RELAY IS 39794-SDA-A03. *TR

MY WIFE TRIED TO OPEN THE (POWERED) LIFTGATE VIA THE HANDLE. THE LIFTGATE WOULD NOT OPEN THIS WAY. WHEN SHE TRIED THE REMOTE, IT OPENED IT APX 90 PERCENT OF THE WAY. WHEN IT REACHED THE APX 90 PERCENT MARK, IT SEEMED THAT THE MOTOR OPENING IT JAMMED AND THE GATE CAME DOWN QUITE QUICKLY, FALLING UNEXPECTEDLY ON MY WIFE'S BACK. I RESEARCHED THIS PROBLEM AND SAW THAT THERE IS AN OPEN INVESTIGATION ON THIS SAME MATTER (NHTSA CAMPAIGN ID NUMBER: PE11034). *KB
