On September 14, 2026, my 2020 Honda Odyssey experienced a sudden, severe low-pressure fuel pump failure while idling/parked. The engine began running extremely rough, surging repeatedly between 300 RPM and 1,000 RPM, knocking, and stalling. I was parked at the time, preventing a severe accident. Upon trying to restart, the vehicle turned over multiple times and would only catch when depressing the accelerator pedal, accompanied by cylinder knocking and an engine thermal spike. The vehicle was towed to an independent repair facility (Tuffy Auto Service). The diagnostic scan confirmed DTC P0087 (Fuel Rail/System Pressure - Too Low). A mechanical gauge test showed the low-side fuel pressure dropped to 10 PSI (far below the standard operating pressure of 50–60 PSI). The shop verified that the in-tank low-pressure fuel pump assembly failed internally and requires complete replacement. This failure, symptom pattern, diagnostic code (P0087), and component match the exact defect profile in NHTSA Recall 23V-858 (Denso Low-Pressure Fuel Pump Impeller Failure). However, when checking my VIN, American Honda claims this specific vehicle is excluded from the recall range. American Honda Consumer Relations subsequently refused goodwill assistance due to non-dealer service history and vehicle resale status. This creates a severe safety hazard. A vehicle experiencing a sudden drop to 10 PSI fuel pressure while driving in traffic will lose motive power, stall unexpectedly, and disable power steering and braking assist. I am submitting this report because American Honda has failed to include all affected production batches in Recall 23V-858. I request NHTSA expand Recall 23V-858 to include out-of-range 2020 Honda Odyssey VINs exhibiting identical low-side fuel pump failures.

Stopped at a light, auto idle stop engaged, engine shut off normally. The moment I pressed the gas, everything died — engine and all electronics. I pressed the start button two or three times with no response, then it finally started. It was still in Drive. The hazards wouldn't turn on right after, then everything gradually came back to normal.

Several months ago my wife was driving when the automatic brake system engaged when a car was turning in front of her. This engagement startled her and she felt the emergency braking was unnecessary considering the speed and distance the car was in front of her. This incident concerned her and made her lose confidence in the safety of the car. Then just recently we began encountering a almost consistent but sometimes intermittent brake System Error along with multiple trouble notices about problems with Road Departure Mitigation System, Lane Keep Assist System, Collision Mitigation Braking System, Adaptive Cruise Control, etc.. when using the car. We received an error code U3000-49 reporting an Internal electronic failure in the multipurpose camera unit. Online searches of this issue seem to be very common and concerning on how many are occurring considering this is a safety system. Our van has approximately 54,000 miles on it.

The driver side rear coil spring broke abruptly on both the top and bottom leaving the majority of the spring mechanically unattached. The driver side rear shock also broke from the additional strain on it. With a complete loss of suspension on the rear driver side, as I hit bumps on the freeway, I could feel the van jerking quickly nearly sending me out of the lane. If it was slippery with rain or snow, I felt like the van would spin out. The broken parts were confirmed and shown to me by an independent service center. The shop also informed me that he has seen many Honda Odysseys from the same model year with broken coil springs. When he called to order parts from the Honda dealer, none of the 3 nearby dealers had springs in stock and all had vans in their service center waiting to replace their broken springs. There were no warning signs before this happened. I perform all regular maintenance such as brakes, tire rotations/replacements, and oil changes by auto shops so the car is regularly looked at. This happened at 6 years old and 60,000 miles. While springs generally lose some tension, snapping through in two places is unacceptable. Honda has recalled other vehicles for rear suspension failures and needs to expand that recall to additional vehicles. Specifically the Odyssey.

I randomly received a series of 6 warning messages when starting the car on 9/3/26. They were all warnings related to the automatic safety features such as lane departure, collision detection, auto bright lights, etc.I took it to the dealer on 9/4/26 & they diagnosed an internal failure with a multi-purpose camera embedded in the rearview mirror. The dealer ordered a new part, installed and reprogrammed and recalibrated the camera. This vehicle has been owned only by me, is kept in a garage away from weather exposure, there is no reason for this part to fail on a 6 year old car with a hefty cost to the consumer.
