Owner reports
Selected complaints filed with NHTSA by 2018 Honda Odyssey owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2018 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed, but the vehicle failed to accelerate, requiring the contact to forcefully depress the accelerator pedal to move the vehicle. The contact stated that multiple warning lights unexpectedly illuminated, including the Road Departure Mitigation system, Collision Mitigation Braking System, and Lane Departure Warning system warning lights, and all related safety features failed to operate. The vehicle was not diagnosed or repaired. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 105,000.
The contact owns a 2018 Honda Odyssey. The contact stated that while slowing and then attempting to accelerate, the vehicle hesitated while depressing the accelerator pedal. The contact stated that the delay was approximately two seconds before the vehicle accelerated as needed. The vehicle was taken to the local dealer who was unable to duplicate the failure but no cause for the failure was found. The contact stated that the failure had become progressively worse. The manufacturer was not yet contacted regarding the failure. The failure mileage was 40,000.
The contact owns a 2018 Honda Odyssey. The contact stated that on several occasions, while at a stop or rolling to a stop, the vehicle hesitated before accelerating and then abruptly accelerated. There were no warning lights illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, and filed a complaint and referred the contact to the local dealer for a diagnostic test. The failure mileage was approximately 61,000.
I am having an identical issues as described in NHTSA ID Number 11526094. Vehicle hesitates when accelerating from a stop. Have been almost hit a couple times as it is unpredictable when this happens. This is a dangerous behavior and I cannot in clear conscience sell this minivan to another family. I have returned it to the dealer multiple times and they were eventually able to reproduce the problem and captured the behavior on diagnostic equipment. Their finding is that when the accelerator is slightly pressed, and then release (like one might do when entering an intersection to make a left hand turn) the transmission jumps to 5th gear. When the accelerator is pressed to complete the left turn, the transmission spends several seconds shifting from 4th to 3rd to 2nd before finally accelerating. This delay opens up the opportunity to get hit. …
I have had four diagnostics on this vehicle and it's pointing to sensors which are inside the transmission transmission was not leaking and wasn't slipping or nothing I went to get in the vehicle after it was sitting for an hour and I put it in reverse it went right back in the park I put it in dry went right back in the park I couldn't get it out of the park and it was saying on the dash that stop driving one safe transmission problem emission system problems okay like a four diagnostics that are saying that it is sensors transmission pressure sensor A park neutral switch is bad power source failure steering angle low voltage sensor failure four different things I cannot get any help I hear a bunch of different stories some are saying the transmission not so we're saying it's not a transmission isn't slipping I drove it car was fine it won't go into drive I've been told and I …
One week ago, I was driving on a highway, accelerating to the 65 MPH speed limit on that road, my van's accelerator completely stopped responding. Despite pumping the pedal repeatedly, I was unable to control my speed at all, and the car continued to lose speed. I had my three children in the car at the time, and given that people regularly go in excess of 70 MPH on that road, I was in danger of not being able to exit the road and/or being hit. I was able to coast off of onto an exit, and the car started responding at speeds of 30 MPH, but it was lurching and jerking while driving. We immediately had the vehicle inspected by an independent mechanic and have been advised that the transmission needs to be replaced. There were no warning lights for this failure. The car also had an incident about a year ago where all lights came on and it stopped responding. …
The Honda sense front facing camera has went out on my 2018 Honda Odyssey. The camera is currently still installed in my van and if it is necessary to replace to keep it from draining the battery I will request that the faulty part be provided to me. This camera being faulty causes the loss of cruise control, adaptive cruise control, auto high beams, lane keep assist and emergency breaking. This issue is also causing a drain on the battery, which impacts other items due to low voltage. My van is currently at the dealership and I am being told that I will have to purchase a new camera which will be around $1500. The following lights are on; BREAKS, ACC and LKAS. These items first appeared within a few weeks of having the rear camera recall completed. Based on my research this is a common problem and just like the rear camera recall, Honda should have to replace this camera as well. …
Since 2020, we have noticed that the 2018 Honda Odyssey we own will not accelerate when the gas pedal is pressed. There is a noticeable delay between 1 to 3 seconds for the vehicle to accelerate. Once the vehicle accelerates, it does so at an increased rate of speed that is dangerous and scary. This has led to 100+ near miss collisions with pedestrians and other oncoming vehicles at 4-way lighted intersections, highway on-ramps and other driving scenarios. This has caused me and my family traumatic stress (injury) as we've had so many close calls due to Honda's manufacturing failures and failures to address this problem. We have to drive extra cautiously and under stress in anticipation of the acceleration delay. We took to the dealership several times and they said there appears to be no issue even though I'm certain they didn't do thorough test drive to inspect problem. …
My van has been having increasingly frequent speed control problems. When attempting to pull out from a stop, the gas pedal will become unresponsive. Then, I will press the gas pedal harder and the vehicle will burn rubber. This happens intermittently, but at least 3-4 times a week. The most dramatic example of this happened, yesterday, while I was trying to make a left turn cross two lanes of traffic with children in my vehicle. I lightly pressed the gas, rolled out into the intersection, lost gas pedal response. I pressed the pedal hard to attempt to move out of path of oncoming traffic where I was stalled. The car burned rubber, then immediately lost gas pedal response again. I had to again press the gas pedal and burn rubber a 2nd time to get out of the way of oncoming traffic. Losing all gas pedal response while oncoming traffic is approaching is terrifying. …
The battery in our van weakened and needed to be replaced. Upon replacement with brand new battery, a ton of new warnings began. These included problems with: Adaptive cruise control; lane assist; collision avoidance; auto high beam, and maybe another. Doing some research online, I found that many other Odyssey owners experienced similar issues associated with battery replacement. Local Honda dealer told me the MOST recall repair may take care of it. It did not. Was told the internal front multipurpose camera just happened to coincidentally go out at the same time as the battery. Honda wants $1500 to replace the camera. Honda USA declined to help. In the meantime, our vehicle has none of the safety features available; and regular cruise control is not an option if the camera is not replaced. …
