| Aug 2025 | FORWARD COLLISION AVOIDANCE | On July 30, 2025, my Honda’s Collision Mitigation Braking System (CMBS) randomly activated without any obstacles in front of the vehicle. Since then, this issue has happened numerous times while driving. When the incident occurs, the system flashes a “Brake” warning and suddenly applies the brakes while I am driving. This creates a serious risk of a rear-end collision, loss of control, or bodily harm. I had the vehicle inspected by an authorized Honda dealership on August 1, 2025 for this issue. Despite the inspection, the malfunction continues to occur. Although I have not yet been involved in an accident, this defect poses an ongoing safety hazard for myself, passengers, and others on the road. I request that NHTSA investigate this matter. | Crash: No Fire: No | Unknown |

The lights stayed off for about 3-4 days and then the same thing happened again. I took it to the dealership to be checked out and they told me that the head gasket had failed and coolant was leaking into the cylinder and causing the engine to overheat. | Crash: No Fire: No | Unknown |

| Aug 2025 | UNKNOWN OR OTHER,ENGINE,FUEL/PROPULSION SYSTEM | My car displays every single light on the dashboard it’s been happening for about a year. It starts to shake when I turn it on sometimes it does it sometimes it doesn’t but now it’s a reoccurring issue and has been happening for the past six months we’ve brought it to everywhere. The engine is stalling and won’t go over 20 mph. I’m lucky if it gets to 40 . There’s a recall on my car, but my van is not covered underneath it. Looking to see if this can be looked into since so many people I have spoken to says that that’s what they’re experiencing until they got the recall fixed | Crash: No Fire: No | Unknown |

| Jul 2025 | STEERING,SUSPENSION,SERVICE BRAKES | I noticed a loud grinding noise and reduced braking power coming from my 2020 Honda Accord while driving at normal city speeds. A local mechanic inspected it and found that the rear brake caliper was sticking and causing premature wear. I contacted Honda service, but they refused to cover the cost or inspect it under goodwill, even though similar issues have been reported with other Honda models. This issue puts my safety at risk as braking is compromised and steering becomes harder. The problem was confirmed by a local certified mechanic and is available for inspection if needed. | Crash: No Fire: No | Unknown |
