2019 Honda Odyssey: engine overheating

Filed Sep 15, 2026 · Driver assistance, Electrical · TX

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 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.

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.

The DTC U300-49 suddenly failed which affects many of the security systems on the 2019 Honda Odyssey. Upon research, this is very common on the Honda Odyssey caused by it overheating which seems like it should be a dangerous part. It is such an expensive part that we as the consumer have to replace and it should be Honda replacing it if it is their fault that this part fails often. I haven't replaced it as we don't have the funds to replace it, so hopefully it won't pose a safety threat as there are 5 warnings showing on my screen daily.

Either the ADAS camera or the radar sensor in the van is not functioning properly. The odyssey has know issues like the camera overheating and dies or the radar can be mis aligned by going through a car wash. We do not know which is not working in our van but we are now locked out of basic features on the van. The biggest problem is that cruise control no longer functions. I had previously turned adaptive cruise control (ACC) off and reverted the van to normal cruise control (CC). With the new issue, I al locked out of using CC even though it does not rely on the ADAS camera or the radar sensor.

I own a 2019 Honda Odyssey Elite with 39,000 miles on it. In January 2026, suddenly I had multiple warning lights on in my minivan related to an ADAS system failure. I replaced the car battery and later determined that the ADAS camera had failed in the car. In reading online, this is a very common issue with Hondas as the cameras are known to overheat and require replacement. Warning lights: Brake System Malfunction, Adaptive Cruise Control Problem, Collision Mitigation System Problem, Lane Keeping Assist Problem, Road Departure Mitigation System Problem, Auto High Beam Problem Before I was able to get it repaired, the van turned off suddenly in traffic twice while my wife was driving the car while also one of my children was inside, creating an unsafe condition that could have created an accident. Luckily my wife was able to get the car safely moved out of traffic and we stopped driving the car at that point. I wound up replacing the camera and and needing to get it recalibrated so that the car could be drivable. This resulted in the van not being operable for nearly a month. For a car that had 39,000 miles on it, this really should be something under a longer warranty as it could have created an unsafe driving condition for my family. Total cost to repair = $1634.22.

Several complaints can be seen across many different Honda forums that indicate several years including 2018 - 2023 of the Honda Odyssey are affected by similar issues when the front multi-purpose camera fails. Many have reported extreme heat when physically inspecting the camera unit. The ZYNQ XA72030 chip manufacturer, AMD, has listed known issues with this particular chip overheating either due to inadequate cooling (this is a passively cooled chip), poor PCB layout, unstable or undersized power supply, all which can result in thermal shutdown. At startup my vehicle dash immediately lit up with several Warning indicating the disablement of multiple systems: LKAS, EBA, ACC, Collision Mitigation, Lane Departure, Automatic High-Beam. In my case, physical inspection revealed the camera outer shell to be extremely hot to the touch necessitating a rag to reduce risk of burn while handling. It's interesting to see that Honda has issues a recall for the back camera which is not tied to many or any other systems at all due to a faulty cable, yet the front facing camera which directly affects Lane Keep Assist, Emergency Brake Assist, Collision Mitigation, Lane Departure Assist, Adaptive Cruise Control, and Automatic High-Beam, has not received a recall despite the many complaints brought forth. It is clearly a defective component that affects many other systems which can lead to potential crashes under the right circumstances. I would urge Honda to issue a recall for all Odysseys experiencing multiple systems failure due to a defective multi-purpose camera.

As I was driving the car computer showed overheating, brake failure, transmission failure and the car started shaking and the engine died. I had the car towed by triple AAA to a auto repair shop, but the next day when they went to fix the problem could not replicate it.

I had 5 warnings appeared in the dashboard : -Adaptive cruise control problem -Lane keeping assist problem -Collision mitigation system problem -road departure mitigation system problem -Auto high-beam problem and the Amber Brake system light came on permanently Searched the problem on Google and Reddit found many Honda Odyssey owners having the same problem which is a safety issue some people took their vehicle to the dealership and have been told that the windshield camera is causing these warnings to appear because the camera is overheated by the sun, and the manufacturer did not make the camera well ventilated to dissipate heat caused by sun light

Turned on the car the other day and several warnings displayed on the odometer. Adaptive Cruise Control Problem Lake Keeping Assist Problem Collision Mitigation Problem Road Departure Mitigation System Problem Auto High-Beam Problem Other than cruise controls not working, the car works fine. I took it to the dealer, and they said the camera module behind the rear view mirror needs to be replaced. Technician claimed that because my cruise control button was left on, it kept the camera running, and basically overheated the camera to a fault. He mentioned recommending to router owners that they only turn on the cruise control button when they plan to use it, and to leave it off if not. I asked if turning the cruise control button when not in use was referenced in the owner’s manual, but he was unsure. I would have to double check, but I don’t believe that warning is there.

The camera sensor in my 2019 Honda Odyssey EX-L failed due to excessive overheating. The sensor reached extreme temperatures, leading to a complete system failure. As a result, the vehicle became inoperable. The failed component is no longer available for inspection as I was forced to purchase a replacement due to the vehicle’s dependency on it for proper function. The failure of the camera sensor created multiple dangerous situations: Loss of vehicle control: The vehicle lost acceleration functionality and automatically shut itself down, which could have led to a crash in traffic.Dashboard warning lights: All dashboard lights illuminated simultaneously, indicating a severe system failure. Fire hazard: The sensor was emitting extreme heat, creating a potential fire risk due to overheating electronics. Exposure to the elements: The sensor’s placement in direct sunlight likely contributed to its overheating, further increasing the risk of failure. Mandatory dependency on the sensor: The vehicle was rendered inoperable without the functioning sensor, leaving me without a safe means of transportation. A Honda dealership inspected the vehicle and confirmed that the sensor had failed due to overheating. However, they stated that the cost of replacement, installation, and recalibration would be my financial responsibility. The issue was evaluated by a Honda dealership, but no manufacturer action was taken to address the failure beyond suggesting an expensive repair. All dashboard warning lights illuminated simultaneously. Loss of acceleration control occurred before the vehicle shut down automatically. The sensor was emitting extreme heat prior to the failure. The issue persisted after restarting the vehicle—after a 10-minute cooldown, the vehicle restarted but failed again after 3-5 minutes.This malfunction was not only a significant inconvenience but a major safety hazard. The sensor’s location makes it highly susceptible to overheating.
