My 2023 Honda Odyssey, VIN [XXX], has developed an unusually loud noise from the engine compartment when I press the accelerator. The vehicle was purchased in XXX and currently has approximately 78,800 miles. An independent mechanic inspected the vehicle and did not identify an internal engine problem. The mechanic suspects that the high-pressure fuel pump may be the source of the abnormal noise, but this has not yet been confirmed by a Honda dealership. I am concerned that the noise could indicate a developing fuel-system defect and would like this issue documented and reviewed for any potential safety implications. I request that the federal safety agency investigate whether similar reports involving the 2023 Honda Odyssey indicate a defect that may warrant a safety recall.

After stopping the car in a left turn lane in the intersection, the car engine, dash board and infotainment system shut down. No warnings or other items appeared, the car died. After scrambling since it put traffic to a standstill, I shifter to park and returned on the car. Which worked and allowed me to continue. This happened again 1 week later while at a red light.

Seems like due to the auto idle, it makes the engine idle so low that it dies- my car died in middle of the road- the first time, I had it jumped, and mechanic said it was a fluke, second time, despite the testing not showing any issue, he said we can try to replace the battery, so we did, but 6 weeks later my car died, and it took 5 attempts to get it to restart with the external battery pack! each time there was NO issue with the electrical system- my A/C was running fine, the whole dashboard showed up fine. Seems like according to a class action suit in california this is an issue Honda KNEW about! People now know to press the Auto-off button so the car does not auto idle- but this needs to be done EACH time, or you will end up KILLING your engine! How is this allowed to be sold?? I was stuck in MIDDLE of a busy street with my DAUGHTER in the car!!!!

I have a 2023 Honda Odyssey. The engine is making a knocking noise. The oil has just been changed with 5.7 quarts, following the factory specifications, but the knocking is still there. The timing belt tensioner has also been replaced, as well as the high-pressure fuel pump. However, the knocking noise is still present, especially at low speeds.

While driving, the vehicle loses power, hesitates, and jerks, then stalls and shuts off without warning, especially in extreme heat and stop-and-go traffic. The failure occurs more frequently when the fuel level drops below approximately half a tank. After stalling, the vehicle will not restart until it cools down for 20–30 minutes, then temporarily operates normally before the issue repeats. Warning symptoms prior to failure include loss of acceleration, hesitation, and engine overheating. A fuel pump–related fault code has been detected. The vehicle has stalled while driving, creating a serious safety risk due to sudden loss of power in traffic. This condition matches the federal safety agency Recall 23V858000, which states the fuel pump may fail and cause engine stall while driving. The fuel system component believed to be involved is available for inspection upon request. The issue has occurred multiple times and is reproducible under similar conditions.

Our auto idle randomly will shut the entire van off. Leaving us stranded without being able to go for 15-30 seconds until we can get It restarted. There has been no warnings or codes thrown Early on it has been unable to reproduce for them when at the dealership It has been to dealership numerous times because it’s a scary safety issue with cars usually behind us honking, yelling, and holding up a finger. They did try update some software the most recent time which was unsuccessful. Now they want to put a new starter and relay and engine valve adjustment. Leaving me with the bill for something that happened in warranty since they can’t replicate it within a few minutes
