Owner reports
Selected complaints filed with NHTSA by 2014 Honda Odyssey owners, lightly cleaned up (personal details are redacted by NHTSA).
My wife was driving our 2014 Odyssey. She went to visit a neighbor. As she pulled up in the driveway and applied the brakes the car acceleration engaged. She was unable to stop the car. I hit the neighbors garage door, totaling it and damaged both of their cars inside. She had complained previously about what she had described as a braking problem. The car was taken into Honda service to check out the brakes and they were inspected and the car road tested and nothing was found. Since the accident the body was has been repaired and the car was returned to Honda for a diagnostic check-up and nothing was found again. I have a customer service claim with Honda USA but have not heard back from their claims manager.
The contact owns a 2014 Honda Odyssey. The contact stated that the vehicle hesitated while depressing the accelerator pedal, with the check engine warning light and two other unknown warning lights illuminated. The contact initially had the vehicle towed to an independent mechanic where an oil leak was discovered behind the spark plugs. After the initial failure, the contact had the spark plugs replaced four separate times. The vehicle was also taken to a dealer where it was determined that the cause of the failure was the piston rings, and the contact was given an estimate for the repair. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was 93,315.

The contact stated that while operating the vehicle, the instrument panel warning lights started flashing and the vehicle started to lose motive power before coasting to a stop.

The contact was informed that the alternator and rocker arm needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure. The contact was informed that a TSB (20-023) was issued for the failure but the VIN was not included. The failure mileage was 113,000.
On 10/03/2021 I was driving on the road and they car started acting up and the lights on the dashboard all start light up, so I drove to the dealer did a diagnosis on the car came out To be misfire and piston ring 4 fault. So I did the repair that are required for me to operate my vehicle safely. So four years later Honda did the recall. I submitted my documentation and repair receipt. Honda at first denied my claim saying I don't have a proof of payment ( which clearly shows on my receipt it's been paid with a Visa card), so I replied back with the Honda dealer's billing personal contact info so the can verify that it's been paid. So that takes care that. Then they move on to denying me again saying I don't have the correct code on my invoice. …
This started approximately one year plus ago. The problem is exhibited mostly when the vehicle is pulling away after a stop light. From a full stop n pushing the accelerator, the vehicle pulls forward a little n then totally hesitates n stops in the middle of the intersection leaving us in a position to be hit from behind. . Consequently, the vehicle suddenly jerks n moves forward rapidly - again putting us and other drivers at risk. Also, in driving in stop n go traffic, the vehicle suddenly jerks ahead n we are at risk of hitting car in front of us or getting hit from behind. We have had the van to a Honda dealer at three different times, but they are unable to get the van to replicate that motion. There were no warning lights or messages. We have noticed recalls for other vans even up to the 2013 but NOT the 2014 Honda Odyssey!! …
All of this has been diagnosed and confirmed by Richfield-Bloomington Honda. It is a catostrophic failure of the motor. Cylinder 6 is misfiring. They are recommending a full motor replacement. Last year, I had the piston ring issue on this car and the dealership had to rebuild the motor. The van has about 125,000 miles on it and is good service, including the repaired motor. We are the single owners of the vehicle. After this happened, Honda Corporation was notified, a case was open by both the Richfield Honda Dealership where we purchased our vehicle and by our family. Both were denied. This was a huge safety issue. I was driving home and the check engine light started blinking and the car started shaking. I pulled up to the nearest mechanic (4 miles). They recommended towing it the 200 miles to where I had engine work done the previous year. …
I purchased new Honda Odyssey Van in Oct. 2013 (Model 2014) from Auto Nation Honda, Lewisville, TX. I have done services ever since. On 12/14/2021; I was driving on the highway. The check engine light came on along with other lights. The car was vibrating. I pulled the van on the side of 635 Hwy turned the van off, back on, and it persisted. Eventually van was taken to a workshop. I was told nearly a $6,000 repair bill due to piston rings and oil getting into the spark plugs. The van only has 67,980 miles on it. Upon further review, it appears that this is a known Honda issue with this engine (V6, automatic). There are service bulletins covering the 2011-13 model years. I am reading online that now newer model years are experiencing the same issue. It also reads like this issue will come back... I guess starting on the 2014 model years, Honda changed the piston rings. …
My vehicle had check engine line was blinking and I took to the Honda. They immediately diagnosed the code as Cylinder 3 Misfire. Upon checking they identified the root cause is Piston ring needs to replace as oil was leaking in the cylinder. I was told that this can cause severe dame to vehicle and passenger as time engine can stop and cause the fire also. I was told that this issue is well known to Honda. When I reached out to Honda they said that your vehicle is not part of the recall and we cannot reimburse the repair expense. I had maintained my car up to date. There was no maintenances service to replace the piston ring at certain mileage. I am single owner. I am baffled on how this was not the manufacturer issue? How was the scope of the investigation on which vehicle impacted determined? Why was my vin number excluded from recall as certainly it is impacted? …
I purchased this car used in 2018 from CarMax. I have done Honda dealer services ever since. Most recently in December 2021. On 4/6/22; I want to back out of my garage. The check engine light came on along with other lights. The car was vibrating. We turned the car off, back on, and it persisted. We eventually had it towed to a dealer. Yesterday, we were hit with nearly a $6,000 repair bill due to piston rings and oil getting into the spark plugs. The car only (approx) has 78,[redacted] miles on it. Upon further review, it appears that this is a known Honda issue with this engine (V6, automatic). There are service bulletins covering the 2011-13 model years. I am reading online that now newer model years are experiencing the same issue. It also reads like this issue will come back... I guess starting on the 2014 model years, Honda changed the piston rings. …
Repair required piston rings replacements. The vehicle was only 10 years old, 61,000 miles. This is coincidental with the ECO mode shutting down 3 cylinders. As you know, the 2014 model does not have (unlike current models) a special button for the ECO mode, as such, the driver has no control over the feature. While this is a hypothesis, this might have damaged the engine from overuse of remaining cylinders or malfunction of the ones that did not engage in the ECO mode. Research online indicated that other customers reported similar issues. I do not feel it's fair for a vehicle with 61K (sixty one thousand) mileage and 9.5 years old to break down considering the use and the care I have provided for the vehicle throughout its life. …
