2010 Honda Odyssey Engine Problems

The incidents of sudden acceleration while braking on this model are vast. My van has experienced several sudden un-commanded acceleration incidents while braking starting in 2022. Honda lawyers are in control and thus no technical explanation. My last event was on [XXX] post hurricane Helene in Asheville N.C. The response of the NHTSA is needed due to people of modest means need to keep their car as long as possible. This requires honest service information from Honda. Honda has reaped a well deserved dividend cultivating the belief that their product with careful use can last 20 years or more. Honda does not deserve to reap this benefit while failing to execute an honest service which creates an unsafe vehicle. In 2023 the Throttle Position Sensor and its complete assembly was replaced in hope of a resolution. I will now replace the Engine Control CPU after the [XXX] incident. These repairs and expense are un-diagnosed non-OBD supported “shots in the dark” because Honda will not recognize the failure.

Honda service bulletin [XXX] I recently discovered after doing some research on why my 2010 Odyssey is showing cylinder1 misfire code. I replaced the injectors, swapped coil packs, etc. Still cylinder1 misfire issue. Now I find out that Honda is aware of this issue and related to VCM and some rings on piston(s) aligning. Fortunately for Honda, the 8 years unlimited miles is most likely out of a window where statistically the issue will be seen. That is my case. Sept 25, 2021 is when this first started, and has continued to be an issue. I never received notice from Honda since this is a used van. Anyway, I would like some assistance in rectifying this issue for our family van. My local Honda dealer is not even remotely interested in repairing the issue based on [XXX] because of the 8 year extended warranty is no longer applicable. I need help from Honda NA. If you know there is an issue with ring alignment, extending this for 8 years doesn't seem like you are capturing the majority of the problems; most likely a calculated risk... My Odyssey didn't show the issue until 11 years after the 2010 manufacturing date... fortunate for Honda. I need help from Honda on this, even to meet me 1/2 way to cover repair costs. This seems unacceptable to me that an issue as serious as this, known by Honda, and won't be addressed. Please help.

THE CAR IS CURRENTLY REGISTERING INDIVIDUAL CYLINDER AND MULTIPLE RANDOM CYLINDER MISFIRES. WHEN STARTING- THE ENGINE WILL VIBRATE EXCESSIVELY FOR A SHORT PERIOD OF TIME THEN WILL EVEN OUT AND RUN NORMALLY. AT IDLE, THE ENGINE WILL EXPERIENCE MILDLY EXCESSIVE VIBRATION. I HAVE TAKEN THE CAR TO SEVERAL REPAIR SHOPS AND HAVE REPLACED COILS AND SPARK PLUGS. ONE REPAIR SHOP MENTIONED A VALVE TIMING CONTROL CODE ON THEIR DIAGNOSTIC EQUIPMENT. I TOOK THE CAR TO AN OFFICIAL DEALER FOR THE MANUFACTURER AND THEY DID NOT IDENTIFY THIS CODE. THE DEALER INDICATED THAT A VALVE ADJUSTMENT WAS NEEDED. I THEN RETRIEVED THE CAR AND HAD AN ALTERNATE DEALER FOR THE MANUFACTURER DIAGNOSE THE ISSUE. THIS SECOND DEALER SERVICE DEPARTMENT ALSO INDICATED THAT A VALVE ADJUSTMENT WAS NEEDED. THE VALVE ADJUSTMENT REPAIR WAS PERFORMED. THE CAR DROVE NORMALLY FOR A FEW DAYS THEN BEGAN REAND AN GULAR MODERATE TO HEAVY VIBRATION, THE 'CHECK ENGINE' LIGHT FLASHED ON AND OFF THEN EVENTUALLY STAYED ON CONTINUOUSLY. THE CAR WAS RETURNED TO THE DEALER WHO HAD DONE THE VALVE ADJUSTMENT AND THE DEALER INDICATED THAT THE CAR ENGINE NEEDS TO BE REPLACED OR THAT BOTH HEAD GASKETS NEED TO BE REPLACED. I FOUND THAT THERE WAS A CLASS ACTION LAWSUIT FILED AGAINST THIS MANUFACTURER RELATED TO VALVE TIMING CONTROL PROBLEMS LEADING TO CYLINDER MISFIRES AND ENGINE FAILURE WITH AN EXTENDED WARRANTY OFFERED AS A RESULT. I CALLED THE NATIONAL CORPORATE OFFICES AND INQUIRED IF THIS WARRANTY APPLIED TO MY VEHICLE. THEY ADVISED THAT THERE WAS AN EXTENDED WARRANTY RELATED TO THE ISSUES I HAD DESCRIBED BUT THAT THE VIN FOR MY VEHICLE WAS NOT LISTED AMONG THE WARRANTED VEHICLES. I WAS TOLD MY ONLY OPTION WOULD BE TO FILE A COMPLAINT TO SEE IF THE NHSTA COULD REQUIRE THE MANUFACTURER TO INCLUDE MY VEHICLE UNDER WARRANTY FOR REPAIR AS THE WARRANTY RESULTED FROM A LAWSUIT RELATED TO A KNOWN DESIGN ISSUE WITH THE CAR.

THE VEHICLE WAS IN MOTION, WHEN THE CHECK ENGINE LIGHT STARTED FLASHING AND THE VEHICLE STARTED JERKING. I RUSHED TO THE DEALERSHIP AND I WAS INFORMED THAT THERE WAS MISFIRING AND THEY HAD TO UPDATE THE SOFTWARE, REPLACE THE SPARK PLUGS. THEY ALSO INFORMED THAT THE PISTON RINGS WERE LEAKING AND SOME OF THE ENGINE OIL WAS BURNT, I ALSO HEARD THAT THIS WAS AN ISSUE ON THIS VEHICLE THAT OTHERS HAD FACED, A CLASS ACTION LAWSUIT HAD BEEN FILED WHERE HONDA HAD PROVIDED A WARRANTY EXTENSION AND NOT A RECALL, SO THE ISSUE WILL HAVE TO BE HANDLED BY ME. I WAS WORRIED ABOUT MY FAMILY'S SAFETY AND HONDA WAS NOT READY TO RESOLVE THE ISSUE.

ENGINE LOST POWER ALL OF SUDDEN WHEN EXITING HIGHWAY, BARELY GOING UP ON A SLIGHT UPHILL.

ENGINE IS TRIPPING THE CODE "P3497" BECAUSE THE ONBOARD COMPUTER IS MAKING THE ENGINE BURN TOO MUCH OIL. THIS COULD CAUSE A CATASTROPHIC ENGINE FAILURE. RESEARCH INDICATES THAT IT'S CAUSED BY A FAULTY OIL PRESSURE SWITCH ASSEMBLY.

OIL OVERCONSUMPTION, MULTIPLE CALLS TO HONDA AND WAS TOLD MY VIN DID NOT FALL UNDER THE EXTENDED WARRANTY THEY GAVE. FASTWARD TO TODAY 3/26/19 AND THE ENGINE IS SHOT AND WAS TOLD BY THE HONDA DEALERSHIP HERE IN TALLAHASSEE THAT I NEED A NEW ENGINE. THIS IS NEGLIGENCE ON PART OF AMERICAN HONDA. THIS VEHICLE WAS PURCHASED FROM A HONDA DEALERSHIP IN MIAMI IN 2013 AND HAS BEEN SERVICED EVER SINCE AT SOUTH MOTOR'S HONDA IN MIAMI UNTIL WE MOVED UP TO HAVANA, FLORIDA. AFTER OUR MOVE VEHICLE HAS BEEN SERVICED AT FLOWERS HONDA IN THOMASVILLE, GEORGIA.

WITHIN THE LAST 12 MONTHS MULTIPLE TIMES I HAVE EXPERIENCED SUDDEN UNEXPECTED ACCELERATION OF THE ENGINE WHILE BRAKING. WHEN IT HAPPENED, I WAS ON A CITY STREET AND WAS ABLE TO STOP THE CAR BY HARD BRAKING TO AVOID A COLLISION WITH THE CAR IN FRONT OF ME. I THEN TOOK THE CAR OUT OF GEAR (SHIFTED TO NEUTRAL) AND THE ENGINE ACCELERATION STOPPED. THIS HAPPENED TODAY (8/21/18) AND MULTIPLE TIMES (AT LEAST FIVE) IN THE PAST YEAR.

HELLO, I HAVE A 2010 HONDA ODYSSEY. 2-3 MONTHS AGO MY WIFE HAD TO PULL OUR VAN OVER THE ROAD BECAUSE OF A SIGNIFICANT SHAKING (VIBRATION) OF THE WHOLE VEHICLE. SHE GOT PRETTY SCARED AND GAVE ME A CALL. THEN, WE TOOK THE VEHICLE TO THE DEALER THAT WE HAD PURCHASED. WE HAVE BEEN TOLD THAT SPARK PLUGS HAD OIL LEAKED THROUGH THE ENGINE. THEY REPLACED THE SPARK PLUGS AND THE ISSUE OF SIGNIFICANT SHAKING WAS RESOLVED. SINCE THEN, I HAVE BEEN CHECKING THE OIL LEVEL AND EACH WEEK I AM ADDING A QUARTER OF OIL. THEN, I HAVE GONE THROUGH SOME SEARCH AND FOUND THAT 2008-2013 ODYSSEY MODELS ARE POWERED BY A SIX-CYLINDER ENGINE WITH A VARIABLE CYLINDER MANAGEMENT (VCM) SYSTEM. THE SYSTEM IS DESIGNED IN A WAY THAT ALLOWS OIL TO LEAK INTO THE ENGINE'S COMBUSTION CHAMBER, LEADING TO PREMATURE SPARK PLUG DEGRADATION, REDUCED FUEL ECONOMY, AND EXCESSIVE OIL CONSUMPTION. AS A RESULT, MANY ODYSSEY OWNERS REPORT HAVING TO REPLACE THEIR SPARK PLUGS FREQUENTLY AND REFILL THE MOTOR WITH OIL BETWEEN OIL CHANGES. THIS IS WHAT I AM EXACTLY HAVING. I HAVE CALLED HONDA CUSTOMER CARE AND HAVE BEEN TOLD THAT YOUR VAN IS NOT UNDER WARRANTY ANYMORE AS IT IS 8 YEARS 7 MONTHS OLD AND IF IT WAS LESS THAN 8 YEARS, IT WAS GOING TO BE COVERED UNDER WARRANTY. MY CONCERN IS EXCESSIVE OIL LEAKAGE ON A LONG TRIP CAN CAUSE SIGNIFICANT ENGINE HEATING AND/OR SIGNIFICANT SHAKING OF WHOLE VEHICLE MAY REPEAT WHEN I AM ON AN INTERSTATE AND MY WHOLE FAMILY CAN FACE AN SERIOUS ACCIDENT ISSUE. I APPRECIATE YOUR HELPS IN GETTING HONDA TO FIX MY ENGINE AS THIS FIX IS QUITE EXPENSIVE FOR MY BUDGET. THANK YOU VERY MUCH AND BEST REGARDS.

CONFIGURED WITH 1 CHAIR BEHIND DRIVER AND ALL OTHER REAR SEATS REMOVED OR FOLDED DOWN. PAYLOAD CONSISTED OF MYSELF (DRIVER), SPOUSE, 4 GREAT DANE DOGS (550 LBS.), DOG FOOD AND GROCERIES. NO CELLPHONES ACCESSIBLE OR IN USE AND ALL VEHICULAR ENTERTAINMENT FUNCTIONS SWITCHED OFF. ABOUT 4:00 PM THURSDAY MARCH 1, 2018 WEATHER CLEAR, DRY AND AIR TEMPERATURE IN THE LOW 70S EXITED COSTCO (IH10W) PARKING LOT, PROCEEDED OVER IH10W ON BRIDGE TOWARD THE INTERSECTION WITH VANCE-JACKSON RD. AT APPROX. 35 MPH. ENCOUNTERED LINE OF STOPPED VEHICLES BACKED UP FROM THE TRAFFIC LIGHT. USUAL AND NORMAL FORCE ON THE BRAKE PEDAL DID NOT PRODUCE THE EXPECTED SLOWING. EMPLOYING MAXIMUM PANIC FORCE ON BRAKE PEDAL FINALLY BROUGHT THE VEHICLE TO A STOP SHORT OF COLLISION. IMMEDIATELY SHIFTED INTO 'PARK' WHERE UPON THE UNLOADED ENGINE RACED TO HIGH RPM. SWITCHED IGNITION TO 'OFF' WITHOUT REMOVING KEY. DID NOT OBSERVE TACHOMETER DURING THE FOREGOING EXCITEMENT BUT ENGINE SOUND WAS LOUD AND HIGH PITCHED. CHECKED FLOOR AREA FOR OBJECTS OR OBSTRUCTION AND FOUND IT CLEAR. DRIVERS LEFT FOOT BEING FIRMLY PLANTED ON THE FLOOR, ONLY THE RIGHT FOOT HAD ACCESS TO BRAKE OR ACCELERATOR. RESTARTED ENGINE AND PROCEEDED HOME NORMALLY BUT WITH GREAT TREPIDATION AND CAUTION. SUBSEQUENT EXPERIMENT IN A SAFE AREA REVEALED THAT THE ENGINE CAN INDEED BE SHUT DOWN, WHILE IN MOTION, FROM ANY TRANSMISSION SELECTION WITHOUT GOING TO 'PARK' ALTHOUGH WITH CONSEQUENT LOSS OF POWER ASSISTED BRAKING AND STEERING. THIS KNOWLEDGE DOES PROVIDE SOME GUIDANCE FOR ANY FUTURE RUN-AWAY EPISODES. MY SPOUSE WILL BE STRONGLY DISCOURAGED FROM DRIVING THIS VEHICLE IN THE FUTURE. PERHAPS UNRELATED TO THIS INCIDENT (EXCEPTING THE POSSIBLE COMMONALITY OF ENGINE MANAGEMENT COMPUTER), THIS VAN HAS TWICE EXPERIENCED BATTERY DEPLETION DUE TO PARASITIC DRAIN WHEN PARKED OVERNIGHT.

2 WKS AGO 1/7/18 WE NOTICED A TICKING NOISE THAT MY HUSBAND SAID SOUNDED LIKE IT WAS COMING FROM THE ENGINE SITTING AT IDLE OR MOVING..HE CHECKED THE OIL AND THERE WAS NONE THERE..IT WAS NOT TIME FOR A ROUTINE OIL CHANGE AND WE GET THEM DONE REG. AT A NISSIAN DEALERSHIP..HE PUT 2 QTS OF OIL AND LUCAS ADDITIVE TO SEE IF THE NOISE WOULD QUITE DOWN..HOWEVER IT DID NOT AND HAS STARTED TO GET LOUDER..HE THEN WENT TO A MECHANIC FRIEND WHO USED A STETHOSCOPE AND SAID THAT IT WAS COMING FROM THE ENGINE FOR SURE..WE CALLED THE DEALERSHIP WHO WE GOT THE VAN FROM AND THEY SAID TO BRING IT IN BECAUSE THEY DIDN'T UNDERSTAND WHY THERE WASN'T ANY OIL IN IT..THEY SAID THAT THEY DID SOME RESEARCH AND SHOW THAT HONDA SETTLED A LAWSUIT ABOUT FAST OIL COMSUPTION AND ENGINE FAILURE..MY LOCAL HONDA DEALERSHIP SAID THAT THERE IS NOTHING THEY CAN DO BECAUSE THE EXTENDED WARRANTY WENT OUT 9/17 AND IT WOULD NEED TO HAVE A CEL..I ASKED THEM IF THEY WOULD BE ABLE TO START A COMPLAINT WITH AMERICAN HONDA BUT THEY SAID THAT SINCE I'M NOT A CUSTOMER OF THEIR DEALERSHIP THAT IT WOULD BE OUT OF THEIR CONTROL..IT SOUNDS TERRIBLE AT IDLE AND WHEN YOU ARE GOING THROUGH 1ST AND 2ND GEAR..I'M AFRAID THAT IT'S NOT SAFE TO DRIVE WITH MY KIDS IN THE CAR AND WILL STALL OUT ANYWHERE..I DON'T KNOW WHAT TO DO BECAUSE A NEW ENGINE WILL COST THOUSANDS OF DOLLARS AND I'M AFRAID THAT THE VAN IS ONLY WORTH LIKE $6-7000 BUT WE OWE LIKE $12900 STILL

BURNS 2+ QUARTS OF OIL BETWEEN OIL CHANGES

OIL CONSUMPTION PROBLEM MULTIPLE OIL CHANGES AND SPARK PLUG CHANGES HAVE OCCURED

DUE TO EXCESSIVE OIL CONSUMPTION MY CAR ENGINE FAILED AND WAS NOT ABLE TO BE REPAIRED. MY WIFE WAS ABOUT TO GO ON A TRIP AND FORTUNATELY WE HAD IT LOOKED AT OR ELSE SHE WOULD HAVE BEEN IN SERIOUS DANGER OF DRIVING THIS VEHICLE WITH MY CHILDREN INSIDE. I WROTE 2 LETTERS TO HONDA ASKING FOR A NEW CAR OR A CREDIT TOWARDS A NEW CAR. THE SECOND LETTER I RECEIVED A CALL STATING SINCE I DID NOT OWN THE CAR THEY COULD NOT ASSIST ME. THE GIRL, STEVIE, TOLD ME IF I WROTE MORE LETTERS THAT WOULD BE CONSIDERED HARASSMENT????
