NHTSA Complaint #11653632 — 2023 HONDA ACCORD HYBRID

12/22/23: I was accelerating onto the highway when multiple error messages popped up on the screen related to brakes, emission system, power steering, and others. The car’s accelerator lost power and slowed to a stop on the side of the highway. The interior electronics didn’t lose power, and neither did power steering or power brakes to my knowledge. I restarted the car and the warning lights remained on, however the accelerator appeared to function normally. Honda was unable to diagnose or fix. 3/31/25: I was pulling out of a parking deck when the engine lost power (no throttle) at the same time that multiple error messages came on to the screen. I coasted into a parking spot (brakes appeared to work) and turned the car off. I turned it back on and all of the lights had turned off except a warning about the brakes and TPMS (I think). The engine appeared to work normally, and I immediately drove to the Southpoint Honda service center. 4/8/25: Recap from Honda: Your car had a couple issues, they're all related. The first thing you're complaining about the stalling condition that is a known issue. There's a software update that fixes that. So I got it in here to do the software update, but then I could not communicate to the vehicle. The can Gateway module was unresponsive, which the car will run fine without it. But then, I can't talk to the car. So after testing everything and finding the module to have failed, I replaced the can Gateway this morning. Everything's communicating fine and software is updating right now for the module. Then I'm going to update the pgmfi software for the ICM system to correct the communication loss within the network that causes the stalling issue. So those two issues will be corrected.
