2023 Honda Accord Hybrid

Today I was driving my 2023 Honda Accord Touring hybrid with 8k miles on it. Out of the blue, a bunch of warning messages / lights came on ("Brake System Problem. Brake performance may be reduced. See your dealer."; also tire warning symbol). Car automatically decelerated (wouldn't accelerate). This would have been very dangerous happening on a freeway.

The contact owns a 2023 Honda Accord Hybrid. The contact stated while driving 40 MPH, the vehicle inadvertently lost motive power. The driver pulled over to the shoulder of the roadway; however, the vehicle failed to restart. The contact stated that several unknown warning lights were illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the hybrid charging system, resulting in a depleted hybrid battery. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 10,000. The VIN was not available.

The car stalled suddenly with hand brake pulled automatically while driving at a slow speed at a parking lot. The information center shows brake indicator flashing in red with description statements that include the brake might have reduced power and how to restart the car. Was able to start the car after releasing the hand brake and drive without issue. Sent the car to dealer’s service department but they couldn’t recreate the symptom and was told there is no recall for this issue.

Traveling on the expressway at approximately 70mph the dashboard/instrument panel started lighting up with warnings regarding tires, braking, engine, etc, and the car/power started shutting down, could not accelerate, steering and braking became difficult, fortunately I was able to access an off ramp at which point the car was stopped with multiple cars and semis behind me. The emergency flasher did work which most likely saved us from being rear-ended. We turned the car off and then turned it back on twice and then it started up again.

On [XXX], my vehicle’s gas pedal and acceleration system completely stopped working mid-drive on an interstate highway without warning. The car coasted to a stop. After shutting off the car and restarting, the gas pedal worked again. This was the second time this occurred (the first was on [XXX]). I brought the car to my dealer, Bernardi Honda in Natick, as I had done before. They found “loss of communication codes,” and “updated the ECU management system” but since they couldn’t replicate the issue they didn’t know if that would resolve the issue. It did not. They gave me the car back. This would happen a third time on [XXX] and I submitted a report about that, too. I believe my car should be included in recall campaign number 23V588000.

On 6/25/2023, my vehicle’s gas pedal and acceleration system completely stopped working mid-drive without warning. The car coasted to a stop. After shutting off the car and restarting, the gas pedal worked again. I brought the car to my dealer, Bernardi Honda in Natick. They found “loss of communication codes,” but since they couldn’t replicate the issue, no repairs were made and I was given the car back.

On 1/21/2024, the car’s accelerator stopped responding and the car slowed to a stop. This happened twice previously on 6/25/2023, and again on 11/16/2023. Each time, the Honda dealer found “loss of communication codes,” and I was told via text on 1/25/2024 that “your Accord is communicating codes that we don’t have a repair for yet.” I filed a claim with American Honda on 1/31/2024 (case #13919840), and was told over the phone that nothing could be done to resolve the issue. Bernardi Honda gave me the vehicle back without any repairs. I still have the vehicle but I don’t drive it out of concern for my family’s safety.

Driving at low speeds in Somerville MA on [XXX]. 1 yr old car with about $6k miles. It was a hot day. Front display lit up with warning about brakes being degraded and take to dealer. It also showed tire warnings, and traction control warnings. I believe acceleration was greatly reduced. Pulled over. Turned car off and on, and most of the errors cleared, except a brake warning. I drove 5 minutes home. Power cycled again, and the brake warning disappeared. I put a code reader on it, and it showed numerous communications issues. Problem did not repeat. I took to dealer. They confirmed the codes, and communicated with Honda corporate. Honda confirmed they were aware of the problem, but they do not have a solution yet. Google Search showed that it is an isolated problem. If it had happened at highway speeds, it could have resulted in a major accident Attaching code report to show communications errors INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This has happened on two separate occasions, with our purchased-new 2023 Honda Accord Hybrid, which has about 30,000 miles on it. We've had no other issues with this car prior to these two events described below, which happened within in one week of each other. FIRST EPISODE: I was driving on a 4 lane road separated by a median, moving straight ahead at around 30MPH, when suddenly, without any warning from any of the car systems, the displays went completely dark, I was unable to accelerate at all, and had to coast-over into a shopping center parking spot. Once I rolled into the lot (I still had steering), I placed it into park. I waited a few minutes, pushed down the brake and started the car without incident. We took it to a Honda Dealership, but they stated that because there were no warning messages we saw displayed, they would be unlikely to be able to reproduce this, and given we would have had to leave the car for several days without a loaner, we chalked it up to some kind of fluke-glitch. If this had happened on a freeway at higher speeds, this could have caused a serious life-threatening situation (being completely without power, unable to accelerate in fast moving traffic). SECOND EPISODE: This time, I was making a left hand turn and accelerating from a side street onto a main thoroughfare when the car once again lost all ability to accelerate, all screens went dark, and I coasted to the side of the road. There were no warning lights or messages prior to this happening, and once again all display screens were completely dark. Once I coasted to a stop, I put the car in Park, put my foot on the brake, and the car started right up. Had there been any cars coming in either direction, this loss of all ability to accelerate (and all power) could have placed me and other drivers in a serious life-threatening situation. We have an appointment on 6-6-24 with a local Honda Dealership, and it appears others have had this same problem.
