2018 Honda Clarity Plug-in Hybrid problems

“I will first start with our problems/concerns. We had experienced a complete lost power in freeway speed (65 mph) when the battery is depleted, that is when the battery bar goes to zero bar instead of 2 bars usually. I attached a photo from the video I took for your reference. This experience was the engine ramp up and not getting any power while driving on freeway, escpecially obvious during uphill slope. It is a safety hazard where we had to manuver in order avoid traffic since we could not maintain freeway speed. This originally happened around 2022, but we checked with Norm Reeves Honda Cerritos and they told us nothing is wrong and because there was no fault code, nothing they can do. When the Recall service canoaign 24-031 came, we were relieved because we think the problem is going to be fixed. We brought our Honda Clarity to the dealer on 2/3/2025 for the recall and everything was fine (meaning we can drive on HV after our battery is depleted). But around December 2025, my wife experienced the same situation where she couldn’t keep up with the freeway speed after exhausted the electric range of 34 miles. We took it to dealer again on 1/16/2026 and…”

“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. The throttle seems to be the part that failed based on the attached EDR report. The odometer read 34,219 at that time. The car is now considered totaled by GEICO. In addition, Honda Van Nuys has done all maintenance work on the Honda Clarity, including some major removal of the dashboard and back seats, since I purchased the car there in 2018, as outlined in the attachment. I have reached out to Honda Van Nuys and hope your office can encourage them to respond. This is a safety issue. The attachment elaborates further. [XXX]”

“this Honda does not display outside turn signals, found similar problem on Honda Civic and Accord which have recall for this problem. doing research civic and accord have the same body control module as my Honda clarity where the problem is located , I contacted my honda dealer and explained this to service advisor , but he was unable to help me. the car shows fast blinking at gauge cluster turn signal indicator just like turns signals from the civic and accord recalls”

“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”

“The forward-facing Honda Sensing camera mounted behind the windshield (Nidec monocular camera, Honda part number 36160-TRW-A04) failed at approximately 85000 miles on XXX The failure produced simultaneous dashboard warnings and disabled multiple driver assistance systems at once, including Collision Mitigation Braking System (automatic emergency braking), Forward Collision Warning, Road Departure Mitigation, Lane Keeping Assist, and Adaptive Cruise Control. There was no impact, no windshield damage, and no obstruction of the camera lens. The failure appears to be internal to the camera assembly and occurred without warning during normal driving. Because all of these safety systems depend on this single camera, one component failure removed every forward collision protection on the vehicle simultaneously. The sudden appearance of multiple warning lights at once was also distracting while driving. The vehicle is out of warranty and Honda has offered no repair assistance. Dealer replacement is quoted at approximately $1,500 to $2,000 including required camera calibration. This same camera failure is widely reported by owners of Honda Sensing equipped vehicles,…”
