2018 Honda Odyssey was purchased 3/16/2018 at West Honda dealership located in las vegas. Not long after purchase, strong fuel, and similar chemical odor appeared, odor came out of the air vents directly. The odor is so strong that the vehicle would smell chemical and smoky for days. Odor always appeared during driving, the level of strongness caused nausea, cough, and headache. Addressed the issue to 2 different dealerships, with the mention of health concern and fire risk during driving. Both dealerships' service advisors verified the issue verbally, did diagnosis in 3 out of 4 total visits. Could not find the issue while odor presenting in the car; thus, no repair was done to fix the issue. Reports are collected, filed a complaint to the headquarter. Case manager admitted there is something wrong with the vehicle as similar cases with the same type of vehicle are heard from the same area. Being told that no inspection can be done without odor appears again and ignored the previous visits' results.

Sliding doors will not close. Sometimes the door will close almost to the end and then recoil or the door will not close at all (it just beeps). A large number of people appear to be having this issue with all sorts of fixes that are not solving the problem (https://www.odyclub.com/forums/81-2018-Odyssey/309801-driver-S-side-sliding-door-stopped-closing.html#/topics/309801?page=6) and appears related to nhsta complaint number 10136418. Dealer inspected and replaced motors on both doors per Honda's recommendation. Problem immediately reappeared making it so the door cannot be closed unless disengaging the power to the doors, exiting the vehicle, and manually closing the doors. It happens every day and is getting worse.

On March 24, my 2018 Honda Odyssey shifted into park at 65 mph on I-95 in philadelphia. The Honda rep, oliver (a Honda employee), explained to my husband that when the computer in the car connected to the collusion avoidance sensor disconnects, a computer assumes the car is off and that forces the car into park regardless of the speed it is going. This is what happened when I was driving, the entertainment panel screen went blank and while it was rebooting, I lost all control of the car, no gas, no brake, steering was difficult. When it reboot, it was in park and the engine made a terrible noise like metal hitting metal. I was barely able to steer the car to the side of the highly with my three children ages 8 months, 2 years and 4 years old in the car. The Honda rep believes the problem has to do with the way the power cable is connected to the battery. He explain that this caused the sensors to disconnect intermittently. The rep, oliver, blamed the problem on the dealership during their repair of the car for an unrelated issue. However, this is incorrect. The car front sensor have been losing connection to the computer since we took it home before the dealership touched the battery. There are other issues with this car's electrical and computer system that I would not bring up, but oliver's description of the car computer system makes it relevant. He explained that the car has 6 computer connected with ethernet cables. Much of the work for the basic function of the car and transmission is done by the computer that also runs the entertainment system, the big screen common in the front panel of cars. Oliver explained when one computer gets bogged down, it takes the entire system down. Our car and a lot of other 2018 Honda Odyssey have a known flaw that Honda has not fixed in well over a year. The bug, take the camera and retainment system down

On Monday, June 18, 2018 at about 8:00 am my wife was sitting stationary at a stoplight and the window in the rear hatch exploded. There were no other cars/vehicles around her and the weather was clear. The window exploded for no visible reason. The glass shattered everywhere into the rear part of the van and rear seat area. We brought the van to inver grove Honda in inver grove heights, mn (where we purchased the van new in December, 2017) and they refused to classify this as a defect and directed us to file a claim with our insurance company (which we did). They did provide us with a loaner car for free and helped us work with a glass replacement shop. However, I feel this is a manufacture defect, the glass hatch window should not have exploded for no reason.

Push button shifting from reverse to drive is problematic. If the drive button is not pressed firmly enough the vehicle remains in reverse, but the driver thinks that the vehicle is in drive. If there is a person behind the vehicle and the operator presses the throttle then a possibly deadly accident can occur. When shifting from drive to reverse there is an audio notification (a chime sound) that the vehicle is in reverse. The is no similar notification when shifting from reverse to drive. This is a potentially life threatening flaw.

Customer states intermittently right side sliding door does not close properly, sliding door ajar light comes on while driving, right side sliding door will not close using automatically, having to manually/forcefully push door close, has happened twice dealer ship did not do anything as they are not able to duplicate the issue. This is safety concern as it is happening while car is in motion and the door is opening. With kids on board it is always risky. I stopped letting them sit on that side.

The passengers side sliding door would not open automatically. The open/close button on the dash would not open the door either. The key fob wouldn't open it. We shut off the automatic door feature and the door still would not open manually. This is a huge safety issue. After driving the car home, the door opened without issue.

Brand new vehicle. Approximately 700 miles on odometer. Passenger side sliding door would not close completely; either via the push-button operation or manually. Made a grinding sound when closing and then beeped 3 times. Drove the vehicle to dealership with door ajar (beeping alarms the entire way)

2018 Honda Odyssey elite, 4 months old and 650 miles. While driving on the interstate the moon roof exploded. Sounded like a gun going off. Remanants of the moon roof are shaped upwards showing the explosion came from the inside and not being hit by a rock, etc. No traffic was in front of my vehicle and I wasn't driving under a underpass.

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.
