THE BRAKES ON OUR 07 HONDA ODYSSEY WERE SPONGY FROM DAY ONE. THE PERSON DRIVING THE VAN NOTICED THE PEDAL EVEN GETTING LOWER THE LONGER IT GOT DRIVEN. AT FIRST YOU WOULD BE ABLE TO STOP BUT AS TIME WENT ON THE PEDAL WOULD ALMOST BE AT THE FLOOR TO ACCOMPLISH BRAKING. WE TOOK TO THE DEALER AFTER ANOTHER ODYSSEY VAN WE HAD WAS ALMOST IN A WRECK BECAUSE OF THE SAME PROBLEM. THEY REPLACED THE BRAKE MODULATOR, SAID IT WAS LEAKING AIR INTERNALLY. SEEMS TO BE FIXED AT THIS POINT. WE BOUGHT THREE OF THESE VANS AND TWO HAVE THE SAME PROBLEM?! NO RECALL OR NOTICE TO BRING IN WHEN THEY HAVE A TECH BULLETIN FOR THIS PROBLEM?! *TR

AFTER 3 MONTHS I STARTED TO FEEL A DELAY WHEN SHIFTING FROM ANY GEAR TO DRIVE. BUT IT ONLY DOES IT WHEN THE VEHICLE IS WARM. THE ONLY LOCAL HONDA SERVICE STATION ACKNOWLEDGES THE FAULT, BUT THEY KEEP TELLING ME THAT IT IS A NORMAL SYMPTOM OF AN HONDA VEHICLE. UNTIL TODAY I KEEP FIGHTING WITH THEM BECAUSE, I HAVE TAKEN THE VEHICLES TO OTHER CERTIFIED HONDA TECHNICIANS, AND THEY ALL AGREE THAT THERE IS A PROBLEM IN THE TRANSMISSION WITH THE LUBRICATING PROCESS. *TR

THERE IS A CLASS ACTION SUIT PRESENTLY BEING SETTLED BETWEEN OWNERS OF THE HONDA ODYSSEY VAN (EQUIPPED WITH "RUN-FLAT" PAX TIRES) AND HONDA MOTOR COMPANY AND MICHELIN TIRE COMPANY. THE ISSUE INVOLVES POOR TREAD WEAR ON THESE TIRES, THE FACT THAT THE HONDA VAN WITH THESE TIRES HAS NO SPARE TIRE, AND THE FACT THE TIRE CAN ONLY BE CHANGED BY HONDA DEALERS EQUIPPED WITH THE "CHANGING MACHINE." THERE ARE MANY SUB-ISSUES IN THE CASE WHICH RELATE TO PASSENGER SAFETY AND SECURITY. I HOPE NHTSA IS ATTUNED TO THIS CLASS ACTION SUIT, WHEREIN THOUSANDS OF HONDA OWNERS ARE AFFECTED. I WAS TOLD BY MY OWN HONDA DEALER, THAT TO COST TO REPLACE THE WORN-OUT TIRES, REMOUNTING AND ALIGNMENT, IS OVER $1,200. YIPES!! WORST YET, A FAMILY IN THIS HONDA VAN COULD HAVE A FLAT TIRE ON A MOTOR TRIP, HAVE NO SPARE TIRE, AND MUST "FIND" THE HONDA DEALER WHO HAS THE PATENTED EQUIPMENT TO CHANGE THE TIRE. IF YOU BREAKDOWN ON A WEEKEND, I GUESS YOU MUST STAY IN A MOTEL UNTIL THE HONDA DEALER (IF THERE IS ONE) OPENS DURING THE WEEK DAYS. THE PAX TIRES ARE A POTENTIAL HAZARD TO THE SAFETY AND SECURITY OF PASSENGERS IN THE HONDA ODYSSEY TOURING MODEL WHICH IS EQUIPPED WITH THESE TIRES. I HOPE NHTSA IS MONITORING THIS CASE, WHICH IS DEFINED AS FOLLOWS: RE MICHELIN NORTH AMERICA, INC.. PAX SYSTEM MARKETING AND SALES PRACTICES LITIGATION (CASE NO.8:08-MD-01911-RWT).

I HAVE NOTICED THAT MY BRAKE PEDAL PUSHES DOWN NEARLY TO THE FLOOR WHEN THE PEDAL IS PUSHED HARD. I FIRST NOTICED THIS A FEW WEEKS AGO WHEN I WAS WAITING FOR TRAFFIC AS I WAS ENTERING THE STREET FROM A PARKING LOT. MY FOOT WAS PRESSING DOWN ON THE BRAKE PEDAL BUT IT WAS ALSO NOT DIRECTLY ON THE PEDAL. MY FOOT WAS OFF TO THE RIGHT. AS THE PEDAL PRESSED DOWN HARDER, THE SAME BRAKING FOOT WAS HITTING THE THROTTLE PEDAL THUS ACCELERATING THE ENGINE. THE CAR BRAKES FINE IN NORMAL TRAFFIC AND OPERATION. I AM FEARFUL THAT IF I OR SOMEONE ELSE USING THE CAR WOULD MAKE A PANIC STOP AND NOT HAVE THEIR FOOT DIRECTLY ON THE BRAKE PEDAL THAT THEY COULD ACTUALLY PUSH THE THROTTLE MAKING THE CAR ACCELERATE INSTEAD OF STOP. I SHOWED THE SITUATION TO THE DEALER FROM WHOM I PURCHASED THE CAR AND IT WAS THEIR OPINION THAT ALL IS NORMAL AND THAT OTHER CARS LIKE MINE DO THE SAME THING. I VISITED ANOTHER DEALER AND THEY TOO SAID THE BRAKE PEDAL IS NORMAL. *TR

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.
