Incident: In Mar 2019, while driving down a highway with my family, the vehicle experienced a sudden engine malfunction while driving, characterized by a flashing Check Engine Light, severe engine shaking, and a dangerous, immediate loss of acceleration/engine power. We had to get the vehicle towed to the dealership. A diagnostic scan revealed fault code P0302, indicating a misfire in Cylinder 2. Upon mechanical inspection, the spark plug in Cylinder 2 was completely fouled and covered in engine oil. At this time, only the fouled spark plugs were replaced, and the PCM software updated. This essentially is a temporary band-aid pushing the problem further down the road. The vehicle only had around 87,481 miles, and was a little over 10 years old. The same thing happened again in Dec 2025, at around 147,979 miles. This time, we had to do an extensive and really expensive repair. The root cause was determined to be premature failure of the engine's piston rings. This is a direct result of Honda's VCM system, which shuts down cylinders during operation, creating a vacuum that forces oil past the piston rings, fouling the plugs, and causing unexpected power loss during transit. I wasn't aware of this known issue until I had to do the major repair, and have now realized that Honda is very well aware of this well known and widespread issue. Request: This mechanical failure represents a severe, documented safety hazard that puts occupants at risk of being rear-ended due to sudden deceleration on active roadways. Honda is aware of this exact VCM defect for certain model years. A manufacturing design defect that causes unexpected highway engine failure does not cease to be a safety risk or a corporate responsibility due to age. Honda should have taken proactive steps to mitigate and prevent this issue. I am requesting that Honda reimburse the cost of the engine teardown and piston ring replacement required to make the vehicle safe to operate again.

Defect investigations
Inappropriate autonomous braking
In a letter dated October 31, 2013, Honda Motor Company (Honda) submitted a recall notice to the federal safety agency'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 (the federal safety agency 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.

Unexpected Closing of Power Liftgate
The investigation found that the liftgate struts were failing prematurely and at an abnormal rate in certain model year (MY) 2008 Honda Odyssey Touring and 2009 Honda Odyssey Touring and EX-L model vehicles equipped with power-operated rear liftgates (note: MY 2008 Odyssey EX-L was not equipped with a power liftgate).Unlike vehicles with non-powered (manual) liftgates, the subject vehicle's liftgate can be opened automatically (via the power liftgate motor) even when the struts are in a degraded condition and can no longer support it in the open position.Consumers standing or accessing the rear cargo area under the liftgate and expecting the liftgate will stay open, can be struck when the liftgate unexpectedly drops, or can be trapped under the liftgate as it power closes, both of which can occur when the system detects and reacts to degraded struts.By contrast, users of a manual liftgate assist in lifting it, and thus notice the lack of support as the struts degrade.Honda is conducting a recall to replace the liftgate struts in approximately 45,747 MY 2008 and early MY 2009 Odyssey vehicles equipped with power liftgates built before a manufacturing change of the liftgate strut assembly that occurred on January 13, 2009 (see the federal safety agency Safety Recall No. 12V‑062 for further details).The vehicles subject to the recall account for 101 complaints, 12 injuries, and 5,630 of the warranty claims shown above (i.e., the MY 2009 and 2010 vehicles built after the manufacturing change experience lower failure rates).In addition, and based on consumer complaints to the federal safety agency, Odyssey vehicles without power liftgates experience lower complaint and injury rates than the Odyssey vehicles equipped with power liftgates (subject vehicles).The reports cited above can be reviewed online at www-odi.the federal safety agency.dot.gov/owners/Searchreference under the following identification (ODI) numbers:10442027, 10441232, 10437461, 10432557, 10430420, 10429962, 10412908, 10401388, 10395475, 10390216, 10343678, 10336744, 10294156

Air in brake system
By letter dated March 15, 2010, American Honda Motor Corp. (HMC) notified the federal safety agency that it will conduct a safety recall (the federal safety agency 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.

Air in brake system
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.

What 2008 Honda Odyssey owners say
Most recent owner complaints, unedited.
I believe that I was sold a car with an unsafe engine. I bought the van from Libertyville Honda in Libertyville on [XXX]. The car had 107K miles on it. A liile over a mounth later the check engine light came on and the van started running bad. When I did some reasearch I found out that a safty report to an iscident dated [XXX] when the car had 107k miles on it. This means that the car was not driven much from the date of the incedent before it was sold to me. The car was sold to me with the same amount of miles as the day of the incent. I believe the issue with the engine was not permently repaired before the car was sold to me. this is the report [XXX]. "Slowing turning into driveway car would not stop RPM at 2k." " Then shifted to neutral where rpm climed to 4k" My safty was at risk because I was driving a car that could have sped up without warning.

Odometer Fraud. The contact purchased a 2008 Honda Odyssey on April 13,2024. The sale was a private sell. The contact stated at the time of purhcase the odometer was recorded at 129,000. The vehicle was taken to the dealer where the contact attempted to use the vehicle as a trade in. The contact was informed that the CARFAX report last recored the odometer reading on April 6, 2024, at 230,000.
The engine malfunctioned, and the car is available for inspection upon request? My safety was put at risk because the car was backfiring in traffic due to the spark plugs filling up with oil. I reported the problem to the Libertyville Honda because they sold me the vehicle about 35 days before the issue started, but I have not heard back from them. I had the Odyssey inspected at Napleton Honda in Oak Lawn. They informed me that piston rings 1-3 needed to be replaced . They also informed me that due to malfunctioning piston rings at least one of the spark plugs was full of oil. The car also needs a new oxygen sensor and this could also be caused by the engine malfunction. No warning lights came on prior to the failure.
The contact owns a 2008 Honda Odyssey. The contact stated that while the vehicle was stationary, the vehicle was leaking gasoline. There was no warning light illuminated. The contact's boyfriend saw and took a video of the vehicle pouring gasoline. The vehicle was not taken to the dealer or an independent mechanic to be diagnosed. The contact stated that the engine was running during the failure. The vehicle will be towed to the dealer but has not yet been repaired. The manufacturer was made aware of the failure and referred the contact to the federal safety agency Hotline for assistance. The failure mileage was unknown.
Incident #1: 1/18/2024, 102k miles. Engine surged to 2k while braking coming to a light. Close to hitting stopped car. Shifted to neutral rpm speed up to 4k. Incident #2: 1/31/2025: 107k miles. Slowing turning into driveway car would not stop rpm at 2k. Then shifted to neutral where rpm climbed to 4k.
The passenger side door of my 2008 Honda Odyssey fell off when attempting to close it and nearly fell onto my child. The automatic sliding door was closing and around halfway closed it fell off of the track and started opening back up unprompted, thus damaging the rear right quarter panel as well. This is a major safety issue as it nearly crushed my [XXX] daughter, but thankfully was caught in time. A man parked near us in the parking lot helped us pick the door back up and said the same thing happened to him, also in a 2008 Honda Odyssey! Prior to the incident, the door would occasionally hesitate to open when button was pressed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
235/65/R16. Tire blew out throwing car to the left in a ditch going around a curve . Air bags went off from impact. Car front had significant damage.
The contact owns a 2008 Honda Odyssey. The contact stated while driving the vehicle at 45 MPH the front passenger tire flew off which caused the driver's front air bag to deploy with no warning light illuminated. The contact stated that after the air bag deployed his vehicle veered off the road and crashed into a cement block wall. The contact sustained injuries and was transported to the Banner Baywood Emergency Room. The local sheriff's department was on the scene after the accident but the contact was unsure if a police report was filed. The contact stated that he sustained injuries from the accident such as his lips were swollen, and received cuts on his face. The vehicle was towed to an impound lot. The dealer was contacted, and the vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 100,000.
The contact owns a 2008 Honda Odyssey. The contact stated that while driving at various speeds, a grinding noise was present coming from the front brakes. The vehicle was taken to the local dealer who replaced the front brake rotors but after retrieving the vehicle the failure persisted. Additionally, while driving, the braking system would erroneously activate causing the vehicle to suddenly stop. The vehicle was taken back to the dealer who was unable to identify the cause of the failure. The vehicle continued to experience the failures and the Vehicle Stability Assistance (VSA) light started to continually flash off and on. The vehicle was taken back to the dealer who diagnosed that the ABS module was faulty and needed to be replaced. The vehicle was not yet repaired due to the part being on backorder. The failure mileage was 209,000.
