I am writing to report an unresolved high-voltage safety defect involving the Motor Power Inverter Module on my 2019 Honda Clarity Plug-In Hybrid. The vehicle's high-voltage hybrid propulsion inverter is emitting a severe, high-pitched mechanical squealing noise during acceleration and regenerative braking.The high-voltage inverter serves as the foundational link regulating current between the lithium-ion battery and the electric drive motor. A failing inverter module presents an immediate, unreasonable safety hazard. Internal failure, thermal runaway, or component degradation within the inverter stack creates an imminent risk of sudden high-voltage isolation fault. This will result in an immediate vehicle stall and a total loss of propulsion while driving at highway speeds, leaving the vehicle stranded in traffic with no power to accelerate out of harm's way, creating a severe crash hazard.Furthermore, an authorized Honda dealership—Visalia Honda (Groppetti Automotive) in California—has failed to properly diagnose, isolate, or resolve this high-voltage drivetrain defect despite the vehicle being brought in specifically for this issue. Despite the component being legally covered under California’s mandated 15-year/150,000-mile extended emissions and hybrid warranty, the dealership has taken no constructive corrective action, allowing a known, physically degraded high-voltage component to remain active on public roadways.Federal intervention and a formal technical investigation into Honda's clarity hybrid propulsion inverter systems are required to address this vehicle stalling hazard before an electrical failure results in a highway collision.

Most recent owner complaints, unedited.
Currently the high voltage inverter is squealing, it is currently at the dealership. They have verified it is the inverter that is malfunctioning but they will not warrenty the repair because they are saying it needs to completely fail and throw a code. This is the right time to fix it prior to catastrophic failure, can you please help.
The contact owns a 2019 Honda Clarity Plug-In Hybrid. The contact received notification of the federal safety agency Campaign Number: 23V858000 (Fuel System, Gasoline); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was contacted and confirmed that parts for the recall repair were not yet available. The contact called several other dealers, including Lake Elsinore Honda (18450 Collier Ave, Lake Elsinore, CA 92530), Diamond Valley Honda (300 Carriage Cir, Hemet, CA 92545), and DCH Honda of Temecula (26755 Ynez Rd, Temecula, CA 92591); and all confirmed that parts were not yet available. The manufacturer was not made aware of the issue. The contact had not experienced a failure.
I am writing to express my serious concern regarding the safety recall for my 2019 Honda Clarity (VIN: [XXX] ). The recall, dated February 2024, pertains to a potential fuel pump failure that could cause engine stalling while driving, posing a significant safety risk. Despite the severity of this issue, I have encountered significant delays and difficulties in getting the necessary repairs completed at my local Honda dealerships. When I contacted them about the recall immediately after receiving notice, I was informed that they do not have the required parts in stock. Furthermore, the date at which the dealers said that they would be receiving the parts continues to get pushed back from the estimated timeframe for receiving these parts, initially stating it would be 2-3 months, but this has been an ongoing issue with no resolution in sight and well past 60 days. This prolonged delay is unacceptable given the potential safety implications. The recall notice clearly states that a fuel pump failure could lead to an engine stall while driving, increasing the risk of a crash. I am deeply concerned about my safety and that of my passengers while operating this vehicle. I respectfully request that Honda take immediate action to: 1. Expedite the delivery of the necessary parts to my local dealership. 2. Provide a firm date for when the recall repair can be completed on my vehicle.

The contact owns a 2019 Honda Clarity Plug-in Hybrid. The contact stated that after refueling and recharging the vehicle, the mile range indicator would display inaccurate mileage range information. The contact indicated that the mile range display would sometimes be far above the range capability of the vehicle and in some cases well below the range that should be achievable with a full battery charge and full tank of fuel. The vehicle was taken to the dealer who performed a software update and hot reset but the failure continued to occur. The manufacturer was notified of the failure but no assistance was offered. The failure mileage was 20,000.
Car engine makes loud banging noise when it is running on gas instead of electrical battery. I had asked Honda dealer to review but they say they can not do anything about it. It is feels as if car making so much banging noise from engine has inherent issue and will eventually catch fire.
