When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2018 Honda Clarity Electric
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Pedestrian alert sounds
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States.

POWER TRAIN
The vehicle exhibits a dangerous electrical defect involving uncontrolled power-cycling. After shutting down the car, it automatically restarts itself in a continuous loop. During these episodes, the dashboard flickers, the drivetrain shudders, and the vehicle becomes unresponsive to manual 'Stop' button or brake inputs. Most critically, the car autostarts while parked in an enclosed garage. As a Plug-in Hybrid (PHEV), once the EV battery depletes, the internal combustion engine (ICE) engages automatically. This creates a life-threatening risk of Carbon Monoxide (CO) poisoning for residents in the connected home. A Honda dealership has professionally diagnosed the cause as a failure of the Body Control Module (BCM). This module failure also causes the anti-theft alarm to trigger uncontrollably and renders the keyless entry system inoperable. This defect turned the vehicle into a life-safety hazard in a residential setting. Visual documentation of the uncontrolled power-cycling and dashboard flickering can be viewed at: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Since last Wed. (9/24/2025), the car started to show the warnings of "Adaptive Cruise Control Problem", "Brake Hold System Problem", "Brake System Problem", "Electric Parking Brake Problem", and "Road Departure Mitigation System Problem" from time to time. I bought this VHonda Clarity Plug-in Hybrid 2018 in June 2023 as the HoneTrue Certified. Then probably the same time, the car lose the EV mode by itself, and only drives in the gas mode. I found this issue and late manually changed it to EV mode. WHile then it again dropped the EV mode during the driving today (9/28/2025). When I tried to press the EV button, it shows "Drive Mode Change Unavailable"! After stopped at home, I re-started the car, I can change it to EV mode.

The steering makes a horrible clunking sound, and is impercice/sloppy. Dealership refused to acknowledge any issue. Increased effort required to stay within lane. Tie rods are not damaged or worn, issue appears to be with steering rack as far as I can tell.

I took it to the dealer Honda of Riverside, California and they told me, indeed your condenser needs replacement and the good news, In California, Honda has extended its warranty. Then, they said, but you need to replace your evaporator and I need to pay $2350.26 and they refused to replace the ac condenser under warranty without replacing the evaporator and paying that much of money. I called Honda for help (goodwill) and after about a month (without having my car and many emails and phone call and time and efforts) Honda final response was "sorry, you have high mileage" Case [XXX] I really need your help to protect me from them.

I received a notice in the mail last YEAR stating that there was a problem with fuel pump in Honda Clarity and there would be a recall. I cannot get my car serviced. Honda will not respond. A dealer said not safe to drive. And they said they have no idea if they will even have parts this YEAR. Help please.

Despite what your website says, there is a recall on this car - for the fuel pump. Honda has sent notice of the recall but they have NO parts and NO timeline for the repair. The dealer advised me not "to drive long distances" in the car - that is not an acceptable resolution. Also, I asked the dealer if they could narrow down part availability to "weeks, months or years" and they told me they could not.

A/C system has gone out for the third time on the Honda Clarity. This is a safety issue in Minnesota due to windshield fogging during the winter. The A/C system is used to dry the cabin air and prevent fogging. Honda had an extended warranty on the A/C condenser, however, now the A/C evaporator is failing under the same conditions. Dealer wants $2832 to repair.

I was driving straight, no objects in my way, 100 yards behind the car in front of me, and the car automatically breaked with the brake sign flashing on the dash and dinging, bringing me to almost a full stop without my ability to control the car. I had been going ~50mph. It was jarring. I lurched forward, bags and anything on seats flew off. The car behind me almost hit me. There was no reason for the stop. The car has NEVER done this before. I drive 500 miles per week commuting.

The infotainment display camera combination is the worst system in any vehicle I’ve seen that has these installed. If it is daylight the screen is nearly impossible to see anything plainly.

The engine revs very high and the car dramatically slows down. This has happened three times (including today) in the two years I have owned the car. Once was extremely dangerous as it happened on an Interstate highway when traffic was at highway speeds. We were able to avoid getting in an accident though. Why is there no recall for this common problem with this car?
