2012 Honda Odyssey Problems

My break petal went soft - as in goes all the way to the floor - it has been looked at by 2 different mechanics - no warning lights, no sounds, just all of a sudden no breaks - it has all new break pads, master cylinder, rotors, etc… the break petal is as soft as can be. I can not stop suddenly.

My 2012 Honda Odyssey brake suddenly failed today. I felt the brake paddle was very soft and had to push all the way to the floor and the vehicle would slowly stop. I had to push very fast repeatedly to feel enough pressure on the paddle to stop the vehicle quickly. There is no indications on the instrument panel indicating the failure at all. My car is maintained regularly.

Vcm problems burn oil and misfire code

For several years now, we have misfire issue or code P0304. We continue to change spark plugs cylinders. Both usually last a year or so then they need replaced again. I research the problem, no recall or the like. I did see his report on-line, wondering if it applies to us, Warranty Extension: MIL Comes On with DTCs P0301 thru P0304. Any help would be greatly appreciated.

I own a Honda Odyssey equipped with the Auto Idle Stop (automatic engine start-stop) system. The feature has not operated properly and behaves inconsistently. In addition to frequently failing to engage when the vehicle is stopped, I have experienced several instances where the engine shut off as part of the Auto Idle Stop function and then failed to restart promptly when I attempted to proceed. On several occasions, while stopped at red lights on major roads and highways, the vehicle stalled and took a considerable amount of time to restart. During these incidents, I was unable to move the vehicle when traffic began moving, leaving me stranded in active traffic lanes and creating a significant safety hazard. The delayed restart exposed me and my passengers to the risk of rear-end collisions and other accidents. This issue has occurred multiple times and has caused me to lose confidence in the reliability and safety of the Auto Idle Stop system. A vehicle should not become temporarily disabled in traffic due to the failure of a system intended to improve fuel efficiency. Given the repeated nature of the problem and the potential for serious injury, I believe this issue warrants investigation. On August 7, 2026, I brought my Honda Odyssey to an authorized Honda dealership to diagnose the Auto Idle Stop system due to repeated incidents in which the vehicle failed to restart promptly after the engine shut off at a stop. According to the dealership's service report, the technician stated that they had identified similar complaints from other Honda Odyssey owners and that Honda is currently investigating the concern. The technician monitored live vehicle data and determined that the battery voltage did not drop excessively, the starter was not drawing excessive voltage, and no diagnostic snapshots or fault data were stored by the vehicle at the time of inspection. As a result, the dealership was unable to perform any repairs.

Odometer Fraud. The contact purchased a 2012 Honda Odyssey. It was discovered that there was a mileage discrepancy. The vehicle was a private sale. The vehicle mileage was 117,000 at the time of purchase; however, the title listed the mileage at 14,580. The Department of Motor Vehicle reported that the actual mileage as 214,000.

A few weeks ago a cable for the sliding door on the passenger side snapped. We were able to use it manually until this weekend when the whole door fell right off when sliding it closed.

Cable on passenger side sliding door snapped and door shut without latching on the arm of the person getting in.

piston rings wore out prematurely on our 2012 honda odyssey. this was caused by the vcm system. its a known issue on hondas. it only had 88,600 miles at the time. we were driving our 2012 honda odyssey in december 2023. the check engine light began to flash. it starting running rough. we had it towed to a honda dealer for inspection. they pulled codes p303 and p304. they said the rings were worn and spark plugs fouled. they said this is a common issue because of the vcm. they peformed a rering job and with all parts and labor the cost came to $4000. we are very disgusted that this issue was already known by honda and they failed to place the vehicle on recall or wave the repair cost. they had a previous recall for this issue, but they say it was for a limited time frame. my mother only drives less than 10k miles a year, so the issue wouldnt have happened before 2016, as the miles on her van were still very low. we are issueing a complaint against honda for this issue. we are asking for reimbursement for the repair for the piston ring job which was $4000 while we had the vehicle in for this repair, we were also informed of other issues with the van, and we went ahead with those repairs as well, which brought our repair bill total to over $6419, which is also shown on the same receipt.

Dear NHTSA Advisor, Thank you for regarding my request for warranty coverage for the critical misfire and overheating defect with my 2012 Odyssey Honda Engine 3.5L Engine. Odyssey, as described in Honda’s Service Technical Bulletin 13-081. I must reiterate the severity of my situation: the part required for repair is quoted at $7,500.00—and that does not include labor. This amount far exceeds the current market value of my vehicle, effectively making it impossible to afford repairs without Honda’s intervention, it’s aSafety Defect & Known Manufacturer Issue. The misfiring and overheating problems represent major safety risks for my family and anyone who operates the vehicle. This is not routine maintenance, but a substantial defect that Honda has addressed in its own technical bulletin. I have adhered diligently to Honda’s maintenance schedule throughout my ownership. Attached to this correspondence is a PDF containing the complete Service Technical Bulletin 13-081. I am prepared to provide any additional documentation upon request.

When applying the brake fro my 2012 Honda Odyssey I feel my steering shaking that may cause an issue while driving on Freeway. I have done the wheel balancing on new tires again too... But still i fee the same.

MY WIFE'S 2012 ODYSSEY TOURING WAS PARKED ON THE RAMP TO OUR GARAGE, WITH THE EMERGENCY BRAKE ON. I RELEASED THE BRAKE AND APPLIED SLIGHT PRESSURE TO THE ACCELERATOR WITH THE CAR IN REVERSE GEAR: IT LURCHED BACKWARD AND THE BRAKE COULD NOT STOP IT, THOUGH A NEIGHBOR'S GARAGE DID. WHEN I DROVE IT FORWARD TO PARK IT THE CAR SPED FORWARD THIRTY FEET OR SO BEFORE IT OBEYED THE BRAKE. THE GARAGE WILL NEED A NEW DOOR -- AT LEAST -- BUT THE CAR SUFFERED MINOR DAMAGE, EXCEPT THAT THE TAILLIGHTS WILL NOT GO OFF.

AFTER STOPPING THE CAR HAS TRIED TO ACCELERATE ON ITS OWN WHILE THE BRAKE WAS APPLIED. SIX TIMES SINCE PURCHASE, FOUR TIMES THIS YEAR. I HAVE REPORTED THE PROBLEM TWICE TO HONDA SERVICE AS IT OCCURED TWICE ON THE WAY THERE FOR AN OIL CHANGE. THE CAR WAS DEFINITELY STOPPED AT BUSY INTERSECTIONSA AND TURNING IT OFF DID NOT STOP THE PROBLEM IMMEDIATELY. IT REQUIRED TWO OR THREE ON AND OFFS IN BUSY TRAFFICE. HAVE TRIED TO VIDEOTAPE PROBLEM BUT TRAFFIC HAS SPOOKED MY ABILITY AND CONCERN THAT ENGINE WOULD BLOW, SO LOUD IS THE REARING UP. ONLY AFFIRMATION IS MY WIFE AS AN EYEWITNESS ONCE, AND TWO REPAIR BILLS THAT SHOW REPORT OF PROBLEM IN 2017. ONE IN MAY AND ONE IN NOVEMBER. SERVICE SAYS COMPUTER SHOULD CONFIRM PROBLEMS AND THAT IT IS HONDA, NOT HONDA DEALERS ULTIMATE PROBLEM.

The following referenced items have been in constant or recent trouble status: The two-sliding doors repeatedly have resisted closing for at least a year or more. They are eventually forced to close by manipulation of the track system (i.e. closing mechanism). This issue has repeatedly been brought to the attention of the service team at Clear Lake Honda, and diagnostic tests have been conducted but to no avail. This is definitely a safety hazard. Recently, the rear door refused to close and would not engage either manually or automatically when attempting to close. This issue has been brought to the attention of the service team at Clear Lake Honda as of this reporting.

vehicle loses acceleration power intermittently. No response when pressing accelerator or when speeding up with cruise control. Pressing the gas harder does not help but the vehicle starts working normally a few seconds later. Dangerous on busy roads. I don't think it is a weak fuel pump because it accelerated quickly after an event

Misfire in cylinder 1 Caused van to lose power on freeway almost causing an accident. From 2011-2013 there was a settlement that gave an 8 year extended warranty, but why is it only 8 years when not everyone’s driving is the same? My van was brought to the Honda dealer Check engine light came on, then it flashes

SATURDAY, OCTOBER 6, 2018, WE WERE OUR GRANDCHILDREN TO THE ZOO TRAVELING FROM THEIR HOME . WE WERE USING THEIR FAMILY'S 2012 HONDA ODYSSEY. THE SIX YEAR OLD WAS ON A BOOSTER SEAT IN THE THIRD ROW OF SEATS. I HAD HELPED THE THREE YOUNGEST OUT OF THEIR SEATS AND GOTTEN THEM OUT OF THE CAR WHEN THE 6 YEAR OLD CALLED OUT THAT HE WAS STUCK IN HIS SEATBELT. IT WAS TWISTED AROUND HIM AND I COULDN'T SEEM TO FIND THE RELEASE BUTTON. WHEN I ASKED HIM HOW IT HAD GOTTEN THAT WAY, HE SAID HE LAID DOWN WHILE WEARING IT. HE SAID IT HURT AND SEEMED VERY TIGHT. MY HUSBAND LIFTED THE BACK DOOR THINKING HE COULD GET SOME SLACK FROM ABOVE. INSTEAD, THE UNTHINKABLE HAPPENED AND IT BECAME TIGHTER THAN EVER. WE HAD NO TIME TO ANALYZE THE BELT ANY LONGER; THAT WAS CLEAR. IF HE STAYED THAT WAY FOR LONGER THAN A FEW MINUTES, HE WOULD HAVE DEFINITELY HAD ORGAN DAMAGE DUE TO LACK OF BLOOD SUPPLY. I PUT THE FINGERS OF MY HAND BETWEEN THE METAL PART OF THE BELT AND HIS BODY WHILE MY HUSBAND SPRINTED TO THE ZOO OFFICE. WE WERE FORTUNATE THAT THE TRAPPED GRANDSON REMAINED CALM AND DIDN'T THRASH AROUND OR THE OUTCOME WOULD DEFINITELY HAVE BEEN A WORSE ONE. MY HUSBAND SPRINTED BACK WITH TWO PAIRS OF SCISSORS. THE BELT WAS TOO TIGHT AT THE WAIST TO GIVE ME ANY ROOM TO WORK WITH THE SCISSORS. THEN MY HUSBAND CUT THE SEATBELT FROM ABOVE JUST BELOW WHERE THE BELT ENTERED THE CEILING AND OUR GRANDSON WAS SUDDENLY FREED.

MY SON WAS STUCK IN THE DRIVER SIDE 3RD ROW SEAT BELT. WE WERE STATIONARY IN A PARKING LOT. THE SEATBELT DID NOT GIVE OR TO RELEASE TO ALLOW US TO LOOSEN THE STRAP ACROSS HIS LAP. THE SEATBELT KEPT LOCKING AND TIGHTING ON HIS STOMACH. WE HAD TO CUT THE SEATBELT TO RELEASE HIM.

PURCHASED 2012 HONDA ODYSSEY WITH 49K MILES, LOOKED LIKE NEW INSIDE AND OUT, DEALERSHIP PREPPED VEHICLE, INCLUDING NEW TIRES, A FEW MINOR REPAIRS WERE NEEDED, REQUESTED EVERYTHING BE GONE OVER, VEHICLE SAFETY WAS A PRIORITY. I GAVE THEM AN ADDITIONAL MONTH TO ORDER PARTS AND TO TAKE THEIR TIME TO MAKE SURE ALL WAS COMPLETED PROPERLY. DISCOVERED THE NEW ALL SEASON TIRES WERE REALLY DEDICATED MICHELIN WINTER TIRES AS I AM DRIVING ALL SUMMER, HIGHWAY INTERSTATE. THEY DIDN'T REPLACE THE CORRODED, LEAKING TPMS SENOR/VALVE STEMS, THEY LEFT THE ORIGINAL ONES IN. WHILE ON AN OUT OF STATE TRIP, THE PRESSURE WARNING LIGHT CAME ON. ALSO DISCOVERED THE(2) SAFETY LATCH RECALLS FROM HONDA WERE STILL OPEN AS I AM DRIVING MY KIDS AND OTHER STUDENTS IN OUR VAN. THE DEALERSHIP SALESMAN ENSURED ME ALL WOULD BE TAKEN CARE OF AS HE HAD CHILDREN HIMSELF. HE WAS SENDING THE VEHICLE TO A HONDA DEALERSHIP FOR THE KEY CYLINDER REPLACEMENT. TURNS OUT THE VEHICLE HAD 3 OPEN RECALLS. NON REPAIRED AND THEY ASSURED ME THEY HAD BEEN FIXED. THEY MARKETED THE VAN AS A LOCAL TRADE IN, LATER TO FIND OUT THE DEALERSHIP PURCHASED THE VAN AT AN OUT OF STATE AUCTION. I HAD TO PUT NEW ALL SEASON TIRES ON AND REPLACED THE LEAKING TPMS UNITS, THEY REFUSED TO ACKNOWLEDGE THE ISSUES AS I HAD REPAIRS COMPLETED AT A HONDA DEALERSHIP AND SUBARU REIMBURSED ME FOR THE SMALL REPAIRS, BUT REFUSED TO ACKNOWLEDGE THE TIRES OR TPMS UNITS, DISMISSING ADDITIONAL QUESTIONS. THERE IS NO LOVE OR SAFETY AT THIS SUBARU DEALERSHIP . ALL DOCUMENTATION HAS BEEN FILED WITH THE OHIO ATTORNEY GENERAL COMPLAINT. A BIG QUESTION IS ABOUT THE VEHICLES HISTORY FROM AN AUCTION AND WHAT ELSE HAS BEEN COVERED UP AND NOT DISCLOSED.

LOW BEAMS ARE NOT BRIGHT ENOUGH FOR DRIVING.. CAN'T SEE SEE MOST OR ANY SIGN CLEARLY ON DARK HIGHWAY AND ROADS. VERY UNSAFE AND SCARY TO DRIVE AT NIGHT.

REAR RIGHT SIDE TAIL LIGHT DEVELOPED AN INTERIOR CRACK IN IT AND THERE ARE NO SCRATCHES OR DENTS INDICATING SOMEONE HIT IT. HONDA SAW THE DAMAGE WHEN IT WAS BROUGHT FOR REGULAR SERVICE AND REFUSED TO FIX IT SAYING THAT ITS OUR FAULT THAT THE TAILLIGHT CRACKED. THE MANAGER PRESSED ON THE CRACK WHICH MADE IT COME ALL THE WAY THROUGH.THE CAR IS HARDLY DRIVEN ONLY FOR FAMILY TRIPS AND IS HAND WASHED, WAXED, COVERED AND BEFORE BEING PLACED IN THE GARAGE FOR STORAGE AFTER EACH TRIP. *TR
