2019 Honda Odyssey service brakes problems

“The multipurpose windshield camera module in my 2019 Honda Odyssey experiences an internal electronic/power failure (Diagnostic Trouble Code U3000-49) while driving. This failure triggers a cascade of warning lights across the dashboard, instantly and without warning disabling the entire Honda Sensing driver-assist suite—including Collision Mitigation Braking (CMBS), Lane Keeping Assist (LKAS), Road Departure Mitigation (RDM), Adaptive Cruise Control (ACC), and Auto High Beams.”

“On 8.1.26, while operating my 2019 Honda Odyssey, the vehicle suffered a catastrophic, un-commanded automatic emergency braking event followed by a total failure of the brake-release fail-safe mechanisms. While driving in active traffic, the vehicle's forward-facing sensor system suffered a false-alarm trigger. Due to a severe design and component vulnerability, the Electronic Parking Brake (EPB) switch suffered a simultaneous internal mechanical and electronic hardware failure. Because the EPB switch failed internally at the exact moment of the automatic braking event, the system failed to command a brake release. The vehicle’s wheels locked completely, leaving the vehicle completely immobilized in active traffic. This multi-system failure resulted in an immediate, life-threatening crash hazard. By random circumstance and the grace of God, a catastrophic rear-end collision was avoided, but this was a severe near-fatal safety event. A professional automotive diagnostic scan confirmed that the vehicle's computer retained 2 distinct fault incident codes documenting the internal hardware failure of the EPB switch. The dealership confirmed that the system provides…”

“The incident is that the rear brakes keep wearing much faster than the front. New brake pads do not last after only less then 10,000 miles of driving. Dealership and mechanic expect that there is a caliber issue with the 2019 model that is causing the rear brakes to wear too fast. Manufacturer should remedy this issue.”

“The vehicle was in reverse and started to accelerate uncontrollably in reverse. The car came to a stop after hitting a wall and a car. The uncontrolled acceleration happened when we went about 1 foot onto grass while in reverse. The emissions light was going on and off from time to time. We believe it was inspected by a honda dealership at some point. The vehicle is involved with insurance at this point.”

“On April 13, 2026, I brought my 2019 Honda Odyssey to a Honda dealership in Chicago, IL for a dealer-initiated recall service. The dealer contacted me and asked me to come in. Before the recall service, the vehicle had zero warning lights, zero error codes, and was operating completely normally. Immediately after the recall service was completed, the following warning lights appeared on the dashboard: Brake System warning, Hill Start Assist Problem, VSA (Vehicle Stability Assist) warning, and additional stability/steering system warnings. None of these warnings existed before the service. I returned to the dealership the same day. The service team cleared all error codes. However, within minutes of driving off the lot, all warning lights reappeared. This confirms the issue is persistent and not a one-time post-update self-check. I returned a second time. The service manager stated the warnings were not caused by the recall service and refused to investigate further. The dealer quoted 800 for diagnostic work. I also contacted American Honda by phone and was told they could not intervene. With the Brake System and VSA warnings active, the anti-lock braking system…”

“Multiple safety systems on my 2019 Honda Odyssey Elite have simultaneously failed, including LKAS, ACC, Collision Mitigation Braking System, Auto High-Beam Headlights, and other driver-assist features. The dashboard displays warnings for nearly every safety-related system, and the vehicle disables these features without warning. **Detailed Description of the Problem:** Whenever I start my vehicle, multiple error messages are displayed related to the Lane Keeping Assist System (LKAS), Adaptive Cruise Control (ACC), Collision Mitigation Braking System (CMBS), Road Departure Mitigation, Auto Headlights, and other safety features. These warnings appear together and persist even after restarting the vehicle. Apparently, this issue is widespread among 2018–2020 Honda Odyssey owners, with many reporting the same cluster of system failures. The problem appears to be related to a malfunction in the vehicle’s electrical system, sensors/ cameras, or control modules. In my case, the failures occur without any external damage, weather event, or driver action that would explain the sudden loss of safety functionality. When these systems fail, the vehicle disables critical…”
