COMPONENT FAILURE: 2018 Honda Clarity PHEV Air Conditioning Evaporator Core. Complete refrigerant leak. Available for inspection/repair at Norm Reeves Honda Huntington Beach. Confirmed July 29, 2026, via borescope/UV dye. Repair estimate: $3,151-$3,217. SAFETY RISK: Vehicle is inoperable without A/C on Southern California freeways during extreme heat. Operating in 100+ degree heat causes heat exhaustion, reduced driver alertness, and high accident risk. DEALER/INDEPENDENT CONFIRMATION: Confirmed by Norm Reeves Honda Superstore Huntington Beach (July 29, 2026) using borescope camera and UV dye. Written estimate provided. No independent inspection. MANUFACTURER/POLICE/INSURANCE: No inspections by American Honda, police, or insurance. Component is inside the vehicle and available for manufacturer inspection. WARNING SIGNS & TIMELINE: Aug 9, 2025: A/C blowing warm (95,737 mi); pressure checked as "normal." Feb 16, 2026: Total failure; condenser replaced under TSB 21-017 (101,548 mi). Dealership missed concurrent evaporator evaluation. Apr 24, 2026: A/C failed again (103,562 mi). Dealership photographed active "AC leak," marked "Requires Immediate Attention," but abandoned repair for 3 months. Jul 29, 2026: Catastrophic evaporator failure confirmed (107,857 mi). PATTERN & REQUEST: This documents a pattern where 2018-2021 Clarity evaporator failures follow factory-defective condensers (TSB 21-017). Dealership missed multiple opportunities to diagnose/prevent this (August, February, and April). Vehicle is now unsafe for hot-weather commuting. Reporting to the federal safety agency to establish a record for potential warranty extension/recall regarding concurrent evaporator/condenser failures. Records and photos available. More details in the attached docs.

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 described the situation, dealer came back and said nothing has been found and there were no fault code. After that, the only way that we are trying to do is to avoid the battery to get down to zero miles, but since our battery is only getting 34 miles full charge instead of the 47 miles when it was new (dealer also said this is normal depreciation, I am not sure about that). Again, thank you for helping since losing engine power and speed on freeway is pretty scary and I hope this is enough information for my case. Here are answers to your questions. VIN: [XXX] Mileage: 85300 Dealership: Norm Reeves Honda Cerritos Details: Vehicle losing power on freeway speed after battery is depleted. As described above. First time it happened: Around 2022 First time dealer address my concern rather than told me th INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION A

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

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.
