My name is [XXX], we bought a brand new 2019 Honda Odyssey Elite, we have had problems with this vehicle since day one. They have lied and covered up the issues with this vehicle starting with the infotainment center, transmission slippage, fuel pump and the front camera has been overheating giving us the message that it is overheating and all the lights come on. They have stalled us on these issues and now the extended warranty is up and we want something done about this. We have babied this vehicle the entire time since new and it seems like one problem after another, at this point we are very disappointed from the way we are being treated from Honda. The latest is the front sensor on the front mirror that pops up all the lights on the dash, no one seems to be able to duplicate the problem, now they are on all the time and conveniently the extra extended warranty we bought have since expired, there was a lot of recalls on this vehicle and no one ever seems to be able to send us the recall letters. We really thin the mirror sensor and the transmission are definitely safety issues especially when the mirror shuts all the safety off. The transmission shifts hard at times and we pray that Honda will step up to the plate and do the right thing and fix the other recall issues on this same vehicle as well. We have other Honda vehicles that we have not had any issues with, we just can't understand why we are being treated in this manner, we just want the vehicle fixed.

The windshield-mounted front monocular camera (Honda Sensing unit) overheated and failed/burnt out. This failure completely disabled the Forward Collision Warning, Automatic Emergency Braking, Lane Departure Warning, Lane Keeping Assist, and Adaptive Cruise Control systems, triggering multiple safety system warning lights on the dashboard.

The front windshield camera mounted above the rear view mirror overheats and shuts off, causing a minimum of 14 errors to light up the dashboard screen during driving. This also prevents the back lift gate from opening once parked until the errors are cleared. This has happened multiple times, not always when it is hot and sunny, but the camera module overheats and shuts off anyway.

In August 202, the multipurpose monocular camera failed. My car is a 2019 Honda Odyssey EXL. I was not involved in any accident or incident that would have caused this to fail. When this camera fails 5 warning codes popup: collision mitigation braking system failure , lane keeping assistance system failure, adaptive cruise control failure, road departure mitigation and auto-high beams stop working. The dealer priced the repair at ~$2,100. Many reports are coming up with this failure and it seems driven by overheating of the camera module, a filed camera component, or other unknown reasons.

The engine auto idle system failed at a stoplight. The auto-idle engaged, but when I took my foot off the brake, the engine did not restart. It completely shut down, putting my car in park in a busy intersection. The engine light and an error message flashed briefly but disappeared. I was able to restart the car and drive, however, only after waving several other cars to pass by me. I've noticed recently the restart function lagging, and if I put my foot on the gas too soon, the car lurching and jerking forward (indicating the engine isn't restarting quickly or properly). I recently had a full routine service on the vehicle, indicating battery life is good. No other issues appeared such as overheating.

Our van recently started flashing multiple warning lights every time we started it up. These include "Collision mitigation system problem", "auto high-beam problem", "road departure mitigation system problem", "lane keeping assist problem", "adaptive cruise control problem", and also alerts that there is an issue with our brakes. We took the van into our local Honda dealership and were told the ADAS camera was broken and would need to be replaced. We were told this would cost $2,733 and that there's a chance we will also have to replace the windshield (which is physically fine) for another $1200. The camera breaking is not normal maintenance or expected due to wear and tear. There is nothing physically wrong with our windshield, we have had no accidents, we have kept up on all needed vehicle maintenance. It's my understanding the location of the camera is simply causing it to overheat and blow out the electrical system. Additionally concerning is that even if I did have the money to fix the issue Honda does not have any cameras available. They are on backorder. It means as a driver to three small children I have to assume the nonstop alerts are all benign for at least a month. In the off chance there is a true safety concern such as brakes malfunctioning, I will not know as the alert system is going off at all times.

Failed Component: Direct Fuel Injector Set. The components are currently on the vehicle and are available for inspection upon request. Safety Risk: The failing fuel injectors create a severe engine air/fuel imbalance, which causes engine hesitation, engine stumbling during acceleration, and unpredictable power loss. This puts my family at high risk of a collision, particularly when merging onto highways, crossing busy intersections, or accelerating from a stop. Furthermore, dumping unburnt fuel into the exhaust risks overheating the catalytic converter, creating a potential fire hazard. Dealer Confirmation: Yes. The problem was confirmed by AutoNation Honda 365 in Memphis, TN, on [XXX] (Mileage: 83,452). Manufacturer Inspection: The vehicle was inspected by factory-trained technicians at an authorized Honda dealership. A case was opened with Honda Corporate, but they refused to cover the repair, stating my specific VIN batch was excluded from their warranty extension, despite suffering the exact same failure. Warning Lamps & Symptoms: An "Emissions System Problem" warning and the Check Engine Light illuminated on [XXX]. Incident Description & Cause: Honda is fully aware of this dangerous defect. They issued Service Bulletin 21-010, acknowledging that "debris from the high-pressure pump or the fuel injector machining process can cause internal wear or clogging" in 2018-2019 Odysseys. Following the TSB 21-010 protocol, the dealer pulled code P219A and performed a "Cylinder AF Test." My vehicle failed the test (Cylinder 3 running rich). The Honda technician’s official notes state: "Fail air fuel test need injector set internal failure." Honda extended the warranty to 10 years/150,000 miles for this known manufacturing defect, yet they are arbitrarily excluding my 2019 Odyssey, which has the exact identical internal failure documented by their own dealer. Honda's refusal to issue a full recall leaves all affected drivers at risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C.

Back in the fall/winner of 2024 (could have been 2025) my Honda Odyssey had a recall for a low pressure fuel pump. However, Honda and many other dealers were dealing with hundreds of thousands of recalls, and we’re only recalling the vehicles with actual symptoms. My vehicle was hesitating and experiencing sudden loss of power during acceleration therefore Honda agreed to repair my vehicle. Everything seemed to work fine after that with no issues, but approximately three months later, I was having issues with my vehicle and brought it into my Mechanic, to find out that my high-pressure fuel pump was not working properly. Upon further investigation, I found out that a bad low-pressure fuel pump starves the high-pressure fuel pump (HPFP) of required volume. This causes the HPFP to work far beyond its design limits to build pressure, leading to cavitation (vapor bubbles damaging internal components), overheating, and premature mechanical wear from metal-on-metal friction. When I dug a little deeper, I found out that many Honda owners were dealing with failing high-pressure fuel pumps after having their low pressure fuel pump recall repairs completed. Many in which were in a similar timeframe to mine. Honda offered me no good merit assistance and stated that unfortunately, I would be liable for the entire cost of the repair. It is more than obvious that the failing of my low pressure fuel pump impacted the performance and workload of my high-pressure fuel pump, causing it to fail, which I believe Honda should be liable for replacing. Please look further into this matter to help others like me that had their low pressure fuel pump recall performed, and shortly after needed to replace their high-pressure fuel pump at their own costly expense.

The front-facing Honda Sensing camera in my 2020 Honda Odyssey overheated in a 90deg climate. This triggered multiple dashboard warning lights: Adaptive Cruise Control (ACC) Problem, Lane Keeping Assist System (LKAS) Problem, Road Departure Mitigation (RDM) System Problem, Collision Mitigation Braking System (CMBS) Problem, BRAKE System Problem, and Auto High-Beam Problem. The Honda dealership quoted me $1850 to fix it and they said it was a well-known error. There were NO issues with my car prior to this problem. I keep up with all routine maintenance, oil changes, timing belt and water pump replacements, etc. Not only are these safety features inoperable, but these warning lights are very distracting to the driver, but worse than that- I would be unaware of other system failures since I have so many warnings displayed.
