    Here is an update to the issue I had raised with your office in March-April 2026: Honda Van Nuys performed the 35,000-mile routine maintenance on the Honda Clarity on February 24, 2026. At that time, Honda Van Nuys recommended (and I approved) that they clean the throttle. The odometer read 33,882 miles. I drove the car 337 miles when the unintended acceleration accident occurred on March 18, 2026 – 2.5 weeks after Honda Van Nuys cleaned the throttle. The airbags deployed.…

    Since fuel pump recall fix by dealership, “Emission System Problem” started appearing in my car due to the way fuel pump recall was fixed. They already attempted to fix the issue 5 times but unable to provide permanent fix. Honda corporate office also not willing to help. This is a safety issue as when I drive the car, I smell gas and my car is constantly with dealership without permanent fix.

    I received a letter in October 2024 about an inoperable fuel pump and a recall for the vehicle. However, after 3 months, the dealership does not have the fuel pump replacement pump and does not know when they will receive the part. As a result, I am still driving the car with the fuel pump issue.

    The incomplete recall for the fuel pump is a year old and Honda continues to state that the parts are unavailable. Since this is a safety recall how do I get the car to be in safe working order? Do I have other recourse with Honda? What compels Honda to ever fix this?

    Fuel pump recall. Honda states that they do not have the part and they will contact me once the part is here. It has been months (Dec 2023 recall), I am worried that the car will brake or even worse I may have an accident. Already had and still have tons of electronic issues that Honda refuses to fix even though they lost at the arbitration! They literally told me after the trail: you’re on your own.
