1. ) fuel efficiency is not as reported; it is several mpgs lower under all conditions (highway/city). 2.) safety sensor to alert for pedestrians on sides/front do not work properly. Even service rep at dealership said she has had other reports of it not functioning properly and the sensors/system may need to be 'reset'. it is incredibly dangerous to think these systems can fail without any warning message or notice. Car was at a stop and as it started moving forward, a pedestrian came from the right front and was nearly hit. There were no advance warnings, audio/visual to alert the driver. Also after checking with a friend, we could not trigger the alert walking from right to left (from side to front) of vehicle. No accident occurred, thankfully, but people need to know these systems fail and need to be checked to notify of oncoming pedestrians/bikers/vehicles. I bought this expensive vehicle because it had 'sensors' and thought it would be far safer according to sales guy. Not the case. The public is being misled.

Our new 2018 Honda Odyssey ex has failed twice to respond to the gas pedal. The first time I was stopped at an intersection. I took my foot off the brake and pressed the gas pedal. The engine continued to idle and pushed me out into oncoming traffic. Fortunately after pressing the pedal several times the engine responded. The second time I was on a freeway traveling straight at about 55 miles per hour coasting behind traffic in front of me. Again, the engine did not respond the first time I pressed the accelerator. After about the third attempt, the engine responded. I took my car to the Honda dealer. They kept overnight to test it when it was cold and ran diagnostics. They found nothing wrong and said that there is nothing they can do. I hope they figure this out before this car kills me.

The van will stall after stopping. While turning right, I stop at a stop sign, waiting and when it's safe, go to start to turn, pushing the accelerator and the van will stall. It will take me releasing the accelerator and pushing it again to get it to move again. This is terrifiying. This has happened upwards of 20 plus times since purchasing the van in August 2017.

I just got delivery of this new 2018 ex-L w nav+res. The horn on this vehicle is too soft and sometimes on busy highways cannot be heard from other cars when the it is pressed in emergency, especially if the other driver is lessening to radio at moderate to high volume. Compared to previous years Odyssey and other vehicles this model trim has a single horn whereas other had double. The horn volume needs to higher for other to be able to hear

1. failure of the rear entertainment system: The rear camera and entertainment system will lost "network connectivity" and stop functioning 2. brake mitigation system: Spontaneously turns on 3. failure of the infotainment system: The infotainment system will turn off and go into a series of failures, ultimately turning off completely and not functioning. The infotainment system will also experience power errors resulting in errors with the anti theft system. In addition, the radio/speakers periodically stop working.

When driving, my van will switch from drive to park. The van makes a rubbling sound then cuts off. I restart the van the van and it drives. This has happened 4 times in the last month. I'm taking it to the Honda dealer next week.

Vehicle randomly displays a warning that anti-theft cannot communicate and instructs driver to press and hold power. After several failed attempts at restarting the vehicle, we discovered that it meant the radio power, not the push start for the car. It is not clear if this means the radio antitheft or the vehicle anti-theft. The car was stationary and in a parking spot. It happened on start up (and remained there during all 4 restarts). It went away after press and holding the radio power button.
