ON 25-AUG-2016, MY WIFE WAS DRIVING MY VEHICLE HONDA ODYSSEY ON HIGHWAY 210 WEST BOUND. SUDDENLY SHE STARTED SMELLING VERY BAD SMELL AND SHE PULLED THE VEHICLE FROM HIGHWAY AND RIDE INTO GAS STATION. THEN I CALLED AAA FOR HELP AND TOWED THE VEHICLE TO NEAREST MECHANIC SHOP DON'S MOBIL SHOP. THE MECHANIC DIAGNOSED THAT MY VAN'S SPARK PLUG WAS BROKEN AND PIECES OF IT WENT INTO ENGINE'S PISTON AND DAMAGED MY ENGINE. MY VEHICLE HAS CLEAN SERVICE RECORD WITH HONDA DEALER AND MILEAGE ON MY VAN 56K. THEN I TOOK IT TO HONDA DEALER (ROCK HONDA) FOR DIAGNOSIS AND HONDA DEALER ALSO DIAGNOSED THAT ENGINE HAS BEEN DAMAGED BY SPARK PLUG AND COST OF REPAIR IS $3900. THEN I OPENED A CASE WITH HONDA NORTH AMERICA DIVISION FOR HELP US TO FIX THIS ENGINE AS THIS SHOULD NOT HAPPEN FOR 56K MILEAGE AND MY UNDERSTANDING IS THAT THIS VEHICLE WAS DEFECTIVE SPARK PLUG WHICH CAUSED MY ENGINE BROKE. I WAS DOING REGULAR MAINTENANCE WITH HONDA DEALER, THIS NEVER CAME UP DURING MAINTENANCE TIME. HONDA NORTH AMERICA REFUSED TO HELP AND AGREED TO $600 AS GOOD WILL. I NEED HONDA'S HELP TO FIX MY ENGINE. MY VIN NUMBER: [XXX] HONDA DEALER ADDRESS: 16570 S.

SUDDEN, UNCONTROLLED ACCELERATION OF THE ENGINE: THREE TIMES WITHIN THE LAST WEEK OUR 2007 HONDA ODYSSEY STARTED RAPIDLY ACCELERATING (REV-ING) WHILE I WAS APPLYING BRAKES AS I WAS COMING TO A STOP SIGN. I AVOIDED A POSSIBLE ACCIDENT BY APPLYING STIFF BRAKING PRESSURE WHILE RAPIDLY PUTTING THE CAR IN PARK AND THEN TURNING OFF THE ENGINE. ONLY AFTER I TURNED OFF THE IGNITION DID THE CAR STOP REV-ING. THAT SEEMED TO FIX IT THE FIRST AND SECOND TIME BECAUSE WHEN I TURNED THE CAR BACK ON AGAIN, IT BEHAVED NORMALLY FOR THE REST OF THE TRIP. THE THIRD TIME IT HAPPENED AS I WAS SLOWING AND COMING TO A STOP BEHIND ANOTHER CAR, AND AFTER I HAD TURNED OFF THE IGNITION, IT STARTING REVING AGAIN JUST AS SOON AS THE ENGINE STARTED. SO I TURNED IT OFF AGAIN AND COUNTED TO TEN, AND THEN IT STARTED NORMALLY. I TOOK IT TO THE DEALER AND THEY CANNOT FIND ANYTHING WRONG. THEY SAY IT MIGHT BE SOMETHING TO DO WITH THE THROTTLE BODY (WHATEVER THAT IS) AND THEY SAY THEY OPENED IT UP AND CLEANED IT OUT, BUT REALLY COULDN'T SAY WHAT MIGHT HAVE CAUSED IT. THIS IS REALLY SCARY BECAUSE IF I HADN'T BEEN ABLE TO REACT QUICKLY AND APPLY STIFF BRAKING PRESSURE, I COULD HAVE CONTINUED INTO TRAFFIC WHERE I ALMOST CERTAINLY WOULD HAVE BEEN HIT BY CROSS TRAFFIC (THE FIRST TWO TIMES) OR WOULD HAVE RUN INTO THE CAR THAT WAS STOPPED AHEAD OF ME (THIS LAST TIME). (BY "REV-ING" I MEAN THE ENGINE IS RACING, I.E., MAKING LOTS OF REVOLUTIONS PER MINUTE. AS IF THE DRIVER WAS STEPPING ON THE ACCELERATOR PEDAL.)

THE ENGINE STALLS. THIS HAS OCCURRED MANY TIMES OVER THE LAST YEAR. IT APPEARS TO BE RANDOM BUT HAS BEEN OCCURRING MORE FREQUENTLY THE PAST FEW MONTHS. LAST WEEK IT STALLED 3 TIMES. THE STALLING USUALLY OCCURS DURING THE SUMMER MONTHS. IT OCCURS WHEN COMING TO A STOP OR WHEN I AM STOPPED. IT HAS OCCURRED ONE TIME WHILE BACKING UP. YOU CAN TELL WHEN IT IS GOING TO HAPPEN. THE ENGINE SEEMS TO START RUNNING ROUGH. WHEN STOPPED, THE ENGINE WILL BE AT 800 OR 900 REVS AND THEN SUDDENLY DROP THEN JUMP UP AND THEN THE ENGINE WILL SHUT OFF. I PUT THE CAR IN NEUTRAL AND START THE ENGINE. IT ALWAYS STARTS FINE. IT HAPPENS ON HOT AND COOL DAYS, RAINY AND SUNNY DAYS. IT HAPPENS WITH THE AC ON OR THE AC OFF. I HAVE TRIED USING GAS EXCLUSIVELY FROM EXXON AND THEN EXCLUSIVELY FROM BP FOR MONTHS AT TA TIME IN EACH CASE. NO DIFFERENCE. I HAVE TAKEN IT TO A MECHANIC AND TO THE DEALERSHIP MULTIPLE TIMES. NOTHING EVER SHOWS UP ON THE COMPUTER. I EVEN HAD IT STALL AS I PARKED IT AT THE DEALERSHIP. THE DEALERSHIP NOR THE MECHANICS HAVE NOT BEEN ABLE TO FIND A PROBLEM. TO TRY SOMETHING, I HAD THE SPARK PLUGS CHANGED AND A TUNE UP DONE. THE VEHICLE STALLED THE NEXT DAY. I HAVE REPORTED THE PROBLEM TO HONDA AUTOMOTIVE USA. THEY GAVE ME NO HELP OR SOLUTION OTHER THAN TAKING IT TO THE DEALERSHIP. I AM VERY LEERY TO DRIVE THE VEHICLE. I DON'T FEEL SAFE!

I ASK THEN WHETHER THEY CAN LOOK FOR, WHETHER MY VAN HAS THE CORRECT PART (WHICH PROBABLY HAVE), BUT SAID THERE IS A NO WAY TO CHECK UNLESS I HAVE THE INVOICE, WHICH I DEFINITELY HAVE NOT, AS I PURCHASED FROM A PRIVATE OWNER. HOWEVER, THE SYMPTOMS LOOK LIKE THE SAME (WHICH TECHNICIAN COMPLAINT DUE TO FAILURE IN POWER STEERING PUMP, BUT DID NOT TELL ANYTHING ABOUT THE PART, SEE ATTACHED REPORT), THAT IT IS HAVING THE SAME ISSUE, WHICH THOUSANDS OF ODYSSEY OWNER FACED BEFORE. I WANT TO MAKE SURE, THAT IT HAS A RIGHT PART ON IT (EVEN AGED OUT), OR EVEN IT IS FIXED; IT MIGHT HAVE GONE WRONG. I WANT THIS ISSUE IS TO BE RESOLVED AS HONDA SHOULD LOOK INTO THIS SEROUS SAFETY ISSUE, WHICH HONDA ALSO ADMITS BACK IN 2011 (SEE ATTACHED).

Oct 22, 2010
HONDA IS RECALLING CERTAIN MODEL YEAR 2005-2007 ODYSSEY AND ACURA RL VEHICLES. BRAKE FLUID CONTAINING POLYMERS IS USED THAT ACTS AS A LUBRICANT FOR CERTAIN BRAKE SYSTEM COMPONENTS. IF REPLACEMENT BRAKE FLUID IS USED THAT DOES NOT CONTAIN SUCH POLYMERS, OR THAT CONTAINS ONLY SMALL AMOUNTS, A PART OF THE RUBBER SEAL LOCATED AT THE REAR OF THE BRAKE MASTER CYLINDER MAY BECOME DRY, AND THE SEAL MAY CURL DURING MOVEMENT OF THE PISTON. IF THIS OCCURS, A SMALL AMOUNT OF BRAKE FLUID COULD SLOWLY LEAK FROM THE SEAL INTO THE BRAKE BOOSTER.
Consequence & remedy
Consequence: A LEAK OF BRAKE FLUID COULD LEAD TO A CHANGE IN BRAKE PEDAL FEEL AND OVERTIME A DEGRADATION IN BRAKING PERFORMANCE INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE BRAKE MASTER CYLINDER SEAL FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN DURING DECEMBER 2010. OWNERS MAY CONTACT HONDA AT 1-800-999-1009.
Mar 16, 2010
HONDA HAS NOTIFIED NHTSA OF A DEFECT IN CERTAIN MODEL YEAR 2007 AND 2008 ODYSSEY AND ELEMENT PASSENGER VEHICLES MANUFACTURED BETWEEN JULY 28, 2006 AND AUGUST 21, 2008. AIR CAN ENTER THE VSA MODULAR PUMP DURING AN INITIAL SELF-CHECK PROCESS THAT OCCURS SHORTLY AFTER EACH TIME THE ENGINE IS STARTED. IT IS POSSIBLE FOR ENOUGH AIR TO ENTER THE SYSTEM TO RESULT IN A BRAKE PEDAL THAT FEELS SOFT OR LOWER TO THE FLOOR.
Consequence & remedy
Consequence: IF THE OWNER DOES NOT HAVE ANY BRAKE SERVICE OR MAINTENANCE PERFORMED OVER A PERIOD OF MONTHS OR YEARS, THE SYSTEM CAN CONTINUE TO ACCUMULATE ENOUGH AIR TO AFFECT BRAKING PERFORMANCE, INCREASING THE RISK OF A CRASH.
Remedy: HONDA WILL NOTIFY OWNER AND HONDA DEALERS WILL REPAIR THE VSA MODULATOR BY REMOVING ANY EXISTING AIR IN THE BRAKE SYSTEM THEN APPLY SEALANT AND CAPS TO PREVENT AIR FROM ENTERING THE BRAKE SYSTEM FREE OF CHARGE. THE SAFETY RECALL BEGAN ON MAY 3, 2010. OWNERS MAY CONTACT HONDA AT 1-800-999-1009.

3PE13024 · Inappropriate Autonomous Braking
Opened Jun 25, 2013 · Closed Nov 4, 2013
Status: closed (inferred from source dates) · Electronic Stability Control
In a letter dated October 31, 2013, Honda Motor Company (Honda) submitted a recall notice to NHTSA's Office of Defects Investigation describing a defect in the Vehicle Stability Assist (VSA) system in approximately 344,187 model year (MY) 2007 and 2008 Honda Odyssey vehicles produced from August 8, 2006 through September 8, 2008 (NHTSA Recall 13V-500, Honda Recall JC5).The report describes a defect condition caused by a combination of VSA system components and software that is unique to the MY 2007-2008 Honda Odyssey vehicles.The condition may result in unexpected brake application by the VSA system with no brake lamp illumination.The braking forces resulting from the condition can approach the maximum braking capability of the vehicle.Honda's investigation determined that (1) if the yaw rate sensor off-set exceeds a certain value, (2) the sensor calibration is not completed before the vehicle starts moving after start-up, and (3) the vehicle is driven in a specific manner; the VSA system may build hydraulic pressure in the brake system resulting in heavy, unexpected braking without the driver applying the brake pedal.Honda estimates that the parts necessary to correct this condition will not be available until March 2014.Pending part availability, Honda will send interim letters to affected owners including instructions to avoid the defect condition using a procedure to ensure proper VSA system calibration after each vehicle start-up, as well as instructions about what to do if unexpected brake application occurs while driving.Once the remedy parts are available, Honda will send a second notice advising owners to bring their vehicle to their dealer for installation of a redesigned yaw rate sensor.This investigation is closed.
EA09014 · Air In Brake System
Opened Oct 19, 2009 · Closed May 11, 2010
Status: closed (inferred from source dates) · Service Brakes, Hydraulic:antilock/traction Control/electronic Limited Slip:control Unit/module
By letter dated March 15, 2010, American Honda Motor Corp. (HMC) notified the National Highway Traffic Safety Administration (NHTSA) that it will conduct a safety recall (NHTSA Recall No. 10V-098) to address a defect in approximately 412,000 model year (MY) 2007 and 2008 Honda Odyssey and Element vehicles equipped with an ABS/VSA/TCS modulator. The recalled Odyssey vehicles were built from August 2006 August 2008.The recalled Element vehicles were built from July 2006 to July 2008. According to Honda, during an initial self-check process that occurs shortly after each engine ignition cycle, the self-diagnostic software for the VSA modulator allows a vacuum condition that can exist for several hours, allowing air to enter the VSA modulator pump.Over time, and thousands of engine ignition cycles, it is possible for enough air to enter the system to result in a brake pedal that feels soft or lower to the floor.If the customer does not have any brake service or maintenance performed over a period of months or years, the system can continue to accumulate enough air to affect braking performance.To correct the safety defect, Honda dealers will remove existing air in the brake system then apply sealant and caps to the VSA modulator to prevent air from entering the brake system, free of charge. The action taken by Honda is sufficient to resolve the issues raised by this investigation. The agency will continue to monitor this issue and reserves the right to take further action if warranted by the circumstances.Accordingly, this investigation is closed.

Status: closed (inferred from source dates) · Service Brakes, Hydraulic:antilock/traction Control/electronic Limited Slip
THE OFFICE OF DEFECTS INVESTIGATION (ODI) HAS RECEIVED 69 COMPLAINTS, AND HONDA HAS RECEIVED 613 COMPLAINTS AND FIELD REPORTS, ALLEGING LOW/SOFT/SPONGY BRAKE PEDAL TRAVEL IN MODEL YEAR (MY) 2006 THROUGH 2008 HONDA ODYSSEY MINIVANS.TWENTY-SIX ODI COMPLAINTS WERE ALSO REPORTED TO HONDA, RESULTING IN A TOTAL COMPLAINT COUNT OF 656.SOME COMPLAINTS ALLEGE THAT THE CONDITION RESULTED IN EXTENDED STOPPING DISTANCES, INCLUDING SOME REPORTS OF ROLLING PAST STOP SIGNS OR TRAFFIC LIGHTS.THERE ARE 14 ALLEGED CRASHES IN THE SUBJECT VEHICLE POPULATION RELATED TO LOW/SOFT PEDALS. IN RESPONSE TO ODI'S INFORMATION REQUEST FOR PRELIMINARY EVALUATION PE09-024, HONDA INDICATED THAT SMALL AMOUNTS OF AIR MAY ENTER THE BRAKE SYSTEM DURING INITIAL DIAGNOSTICS OF THE VEHICLE STABILITY ASSIST (VSA) MODULATOR WHILE THE PUMP IS BRIEFLY ACTUATED FOR SYSTEM DIAGNOSTICS AFTER THE ENGINE IS STARTED.THE AMOUNT OF AIR GRADUALLY INCREASES WITH EACH SUCCESSIVE ENGINE START CYCLE, RESULTING IN PROGRESSIVELY INCREASING BRAKE PEDAL STROKE.ACCORDING TO HONDA, THE CONDITION DOES NOT PRESENT A SIGNIFICANT RISK TO MOTOR VEHICLE SAFETY BECAUSE THE PEDAL STROKE GRADUALLY INCREASES, PROVIDING THE DRIVER WITH INFORMATION THAT THE BRAKE PEDAL HEIGHT IS CHANGING AND REQUIRES ATTENTION.HONDA HAS FURTHER INDICATED THAT THERE IS NO DETERIORATION OF BRAKING PERFORMANCE CAUSED BY THE SUBJECT CONDITION, EVEN THOUGH THE PEDAL HEIGHT AND FEEL ARE DIFFERENT, UNTIL PEDAL STROKE HAS REACHED THE END OF TRAVEL AND THE DRIVER CANNOT PRODUCE ANY ADDITIONAL BRAKE LINE PRESSURE.HONDA STATES THAT IT IS UNAWARE OF ANY VEHICLES THAT HAVE REACHED SUCH A CONDITION AND HONDA TESTING USING A LEAKING FIELD RETURN MODULATOR INDICATES THAT IT WOULD TAKE OVER A YEAR BEFORE THE PEDAL TRAVEL WOULD REACH ITS LIMIT DURING HARD STOPS WITH 200 N (45 LBF) OF PEDAL EFFORT - THE NOMINAL FORCE REQUIRED TO REACH ABS BRAKING MODE. ODI'S ANALYSIS OF WARRANTY DATA INDICATES THAT THE MY 2007-08 ODYSSEY VEHICLES HAVE EXPERIENCED THE ALLEGED DEFECT AT A RATE OF 0.67%.THE MY 2006 ODYSSEY VEHICLES HAVE EXPERIENCED THE ALLEGED DEFECT AT A SIGNIFICANTLY LOWER RATE (0.04%) THAN THE MY 2007-08 ODYSSEY.HONDA IMPLEMENTED A DESIGN CHANGE IN THE MY 2007 VEHICLES TO CHANGE THE VSA DIAGNOSTIC PROGRAM. THIS INVESTIGATION HAS BEEN UPGRADED TO AN ENGINEERING ANALYSIS (EA09-014) FOR THE MY 2007-08 ODYSSEY VEHICLES TO CONTINUE TO INVESTIGATE THE SCOPE, FREQUENCY, AND SAFETY-RELATED CONSEQUENCES OF THE ALLEGED DEFECT.
