2018 HONDA CLARITY PLUG-IN HYBRID Recalls, Complaints & Safety

I had an unintended acceleration happen as I was easing into a parking spot of a covered parking garage. The car accelerated like a jet plane taking off. I jammed on the brake. The only thing that stopped the car was the concrete wall that was 4 feet away. My airbags activated. We had taken the car to the Honda dealer for its 35,000-mile check-up on February 24, 2026. The Honda dealer has prepared all maintenance, including Honda recalls, since we bought the car in 2018. I'm scared about what caused the unintended acceleration and concerned that others could be injured. Electronic throttle control? Cruise control? Sensors? Wiring problems? What activated it? I believe this is a Honda mechanical problem. I have researched online that others have had unintended acceleration problems with the Honda Clarity and CRV–another plug-in hybrid–but not enough claims to lead to a recall. I have gotten a runaround. Our insurance carrier has declared the car a total loss but refuses to have the computer assessed to determine the cause. The local Honda dealer says it’s not their problem, claiming that we would have to tow the car to them and pay them to replace all safety items. They would then reboot the computer and delete all data, so they could not assess the cause. They said the Clarity has no “black box.” I contacted American Honda Corporation's customer service. Their engineers would not look at the car either unless our insurance company asked and paid them to do it. I have that Case Number. You would think that American Honda Corporation would be concerned, particularly since this unintended acceleration could have killed pedestrians if it had happened on the street or killed me if the concrete wall had not stopped the car. We had the Honda Clarity towed to our house to see if we could find someone to check out the computer. The towing company has driven the car, even though the airbags were activated. After 30 days, our insurance company will take the car for salvage.

Rear camera and Side camera and infotainment system all do not work. Screen does work because we get the welcome message when starting the car. We brought the car to the dealership and they told us that the screen needs to be replaced (Which appears to be working) at a cost of $5400 which they stated may not fix this issue. In addition we tried to get the fuel recall repaired but they told us they could not do it because there is too much fuel in the tank. - The tank holds a total of 8 gallons

The Day Time Running light on the left side of the car just stopped working. The DRL is not damage. I checked for impact marks.

The Honda Clarity's evaporator core has proven to be a defective component requiring premature replacement, representing a significant design or manufacturing flaw. This evaporator failure appears to be a systemic issue affecting multiple Honda Clarity vehicles, as evidenced by [specific sources - owner forums, service bulletins, etc.]. The defect typically manifests as [specific symptoms you've experienced - loss of cooling, refrigerant leaks, etc.], often occurring well before the expected service life of the component. This premature failure not only creates an unreasonable financial burden on owners but also poses safety concerns when air conditioning systems fail during extreme weather conditions, potentially leading to driver distraction, reduced visibility from fogging, or heat-related health risks.

There is an issue with the front, right turn signal light flickering uncontrollably. This flickering is occurring during the vehicle’s operation, posing a significant safety risk as the amber light is incorrectly signaling to other vehicles on the road. The flickering also occurs while the vehicle is parked and off—draining the battery. It has been occurring intermittently with my vehicle for over two years. This issue is widely reported online, with dozens of posts on websites and forums.

The regenerative braking system left paddle (on the steering wheel) intermittently does not work. I press the paddle to slow the vehicle but nothing happens. If I press it multiple times, sometimes it will slow the vehicle, other times nothing happens. I use that method of braking frequently, so when it doesn't work, it jeopardizes the safety of myself and others on the road. This problem has been occurring for a few years; I don't recall the exact date that it began occurring. If needed, I can make the vehicle available for inspection. I've been unable to have it reproduced by a dealer because it usually resolves itself before I can get it in to a dealer to be serviced. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others.

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?

The car stalled and died pulling into high flow traffic almost caused others to hit each other

Several times now while driving on the interstate at the average speed of 70 to 75 which is the speed limit in my Area the battery level while fully charged it's supposed to only drop down to 20% I have noticed several times now while on the interstate I've been barely able to drive 40 mph as it is dropping the power level down to almost zero there is no bars being illuminated they're supposed to be two bars for 20% and even one bar for 10% and twice now in a matter of 2 weeks I've noticed that it goes down to zero bars and the engine is revving very very high and I have very little power available this is quite dangerous on the interstate and I wish this could be resolved or I'll be getting rid of this car

My car was involved in a low speed accident in which the front end of our car hit the rear bumper of the other car. There was no damage to the other car and what appeared to be only minor damage to our front grill. 1) Shortly after the accident, the Collision Mitigation Braking System (CMBS) malfunctioned several times by strongly engaging the brakes when there was no car in front of us. 2) The sudden braking for no reason caused cars behind us to swerve out of the way in order to avoid an accident. Very fortunately, no accidents occurred. 3) The dealer service center confirmed that the accident had caused the sensors for the CMBS to malfunction which in turn caused the brakes to engage. 4) The car has not been inspected. 5) Prior to the brakes engaging, the "Brake Now" warning light came on when there were no cars in front of us. My concern is that the car does not have a safety check to make sure that the sensors are working properly. In addition, the Honda Manual does not warn drivers that even a very low speed accident could cause the sensors to malfunction and the brakes to engage. The CMBS can be turned off by the driver but it automatically comes on every time the car starts. In my view, at the very least, drivers should be warned that if they are involved in an accident, they should disengage the CMBS until an authorized service center can look at the car and make sure the sensors are operating properly. I have contacted Honda and they called me back several months ago, but, to date, nothing has been done. I have attached a picture showing that the damage from the accident appeared to be minor.

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.

Honda has known issues with the AC system in the 2018-21 Honda Clarity (see [XXX] ). About 4 months after I had the faulty condenser replaced, the AC system (including the window defroster/defogger) stopped working again. This time Honda says that the Evaporator Compressor is faulty and needs replaced. Speaking with other Clarity owners, this seems to be a common failure shortly after the faulty condenser is replaced. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The evaporator has failed at just 29000 miles on the car. The condenser was replaced under warranty 2 years ago after it cracked, but the evaporator has now broken and is not covered. This means the AC is not working, which can impact defogging/defrosting, as well as cause unsafe conditions for the driver.

Honda vehicles have an A/C problem affecting the condenser and evaporator. Honda has put a 10 year warranty on the condenser but has done nothing to the faulty evaporator because it is a costly fix. The A/C in my Clarity has been a problem the last 3 years and I have had 3 condensers replaced in the car. I took the Clarity in a few weeks ago and now they are saying that it is the evaporator and want to charge me $3000. The evaporator is needed to also defrost the windows. Please force Honda to fix faulty evaporators in the Clarity.

The A/C evaporator is leaking and it is not working anymore, according to the local Honda Service Center (Pacific Honda San Diego). That's a safety issue because when the A/C doesn't work, the car can't defrost the windshield properly. The local dealership let me know that many cars of the same model are suffering the same issue,

AC stopped working as both condenser and evaporator are leaking. But they only recall condenser currently. They should recall on both. When the A/C doesn't work, the car can't defrost the windshield properly, which is a USDOT defined safety issue.

My air conditioner stopped working in June 2024 following during a long trip in 100+ degree weather since it was blowing only air temperature air. I took it to Honda of Escondido and they determined it was the evaporator. The cost of the repair was ,$2823 on with 64,971 miles on my car. I've been told that it's a safety hazard to drive in a car without AC because of the fact the window defroster won't work, thus making it difficult to drive safely. In addition, during our road trip, we had to keep stopping to get ice water to cool ourselves off. It was not safe to be driving in the car long distance in high temperatures.

Hello, I have received a safety recall notice (23V-858) from Honda back in February and another one in July. I have tried to get them to repair it a few times, but they said they do not have the part yet but should have it sometime in the fall. They are telling me that they are only fixing cars with issues at the moment, which I cannot with 100% certainty say my car has the issue they are talking about. The CSR told me that I would have to pay for diagnostics if they found my car not having the issue in question, which of course I do not want to do. My question is, does Honda not have the duty to fix my car in a timely manner if they have issued a recall for it? I have been waiting for at least 7 months now? That is way too long? Thank you for your attention in this matter [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

NHTSA Recall Number 23V-858, 2018 Honda Clarity PHEV Fuel Pump Impeller recall has not yet been corrected. Honda dealer, Casey Honda, was contacted more than 60 days ago.

The AC evaporator failed with only ~ 35000 miles. This is required to make the defroster work properly, a safety issue. It was replaced at my expense when the condenser was replaced under a mfg recall. There were no warnings lights, just warm air.
