Selected complaints filed with NHTSA by 2023 Honda Odyssey owners, lightly cleaned up (personal details are redacted by NHTSA).
I was pulling into a parking spot with my foot on the brake. My 2023 Odyssey van accelerated instead of braking. There is also supposed to be an auto car warning & braking if you are about to hit a car in front of you. None of this happened! In fact, it crashed into the car in front of me. As soon as it started to accelerate, I released the brake and reapplied the brake as hard as I could. It still hit the car in front of me. It didn't look like there was any damage to their car, but I was very shaken up and now I am worried this will happen again. It happened today, April 18, 2024. My mother was in the car and was as shocked and stressed as I am as the van went from very slow to fast. My body is still shaking. I haven't had it inspected yet. I have an appointment on May 1, 2024, to go to Odonnell Honda. The woman receptionist in the service area said I may have had my foot on the gas. …

The present complaint alleges as follows: 1. Honda has a defective design in the Advanced Driver Assistance Systems (ADAS) of all Honda Odysseys, models 2018-2023. 2. Namely, Honda has placed the RADAR behind the large HONDA emblem on the front grille. This causes the radar to give a "RADAR OBSTRUCTED" warning, which disables all Advanced Driver Assistance Systems in the car (Automatic Emergency Braking, Adaptive Cruise Control, Forward Collision Warning). 3. The "RADAR OBSTRUCTED" warning cannot be reset by restarting the vehicle or disconnecting the battery, requiring recalibration of the RADAR at the cost of $800 each time since it takes several hours to do (per Dealership). 4. The official Honda Odyssey Forum online has countless complaints on the same issue without resolution by Honda. 5. …

While driving 35-40 mph, the car started acting strange, shaking and multiple alerts began appearing. No cars were around me and I was able to get the car over to the shoulder quickly. (Mileage 35,483. Owned car 20 months) Messages appearing: Electric Parking Brake Problem, Adaptive Cruise Control Problem, Road Departure Mitigation System Problem, Collision Mitigation System Problem, Hill Start Assist Problem, Emissions System Problem, Electric Parking Brake Problem, Electric Power Steering Problem, Vehicle Stability Assist Problem, CMBS Problem. I turned car off and on, multiple times, hoping it was a fluke, but car was shaking and messages kept appearing. I called Honda Roadside & car towed to dealership. Was told internal failure of oil pump was the problem. Techline reported Multiple vehicles with same codes and same motor have had the same problem. …
The problems occurred to a brand new 2023 Odyssey only few days (roughly 8 days) after purchase. I was driving the vehicle on road in my community, I came to a STOP sign and stopped, then I was about to turn right but found it was kind of difficult to turn, at same time I heard the sound of crack coming from underneath the steering wheel. I felt that I almost lost control of the vehicle if I did stop at STOP sign, anyway I was able to turn the vehicle as the speed was low and continued to drive slowly. Shortly, several warning icons lighted up on dashboard, including "Auto Engine Idle Stop System Problem", "Lane Keeping Assist Problem", "Adaptive Cruise Control Problem", "Charging System Problem". After that, I drove the vehicle to dealer as soon as I can and dropped the vehicle for diagnosis and repair. …
HONDA CORPORATION IS NOT COMPENSATING DEALERS FAIRLY FOR THIS SIGNIFICANT RECALL ON HONDA ODYSSEYS. THIS RECALL INVOLVES DISASSEMBLING MUCH OF THE INTERIOR TO REPLACE THESE DEFECTIVE COMMUNICATION CABLES. TO DO IT CORRECTLY AND REASSEMBLE THE VEHICLE CORRECTLY THE WORK COULD TAKE 8 HOURS OR MORE. BECAUSE HONDA OF AMERICA IS COMPENSATING DEALERS FOR MUCH LESS THAN THE CORRECT WORK TIME, TO DO THE WORK, HONDA OWNERS ARE HAVING ISSUES WITH THEIR REPAIRS. HONDA'S UNFAIR COMPENSATION TO DEALERS IS CAUSING OTHER MECHANICAL ISSUES ON HONDA ODYSSEY VEHICLES. On another note Honda Odyssey vans have some defective blind spot sensors. When we merge onto the Interstate (if we do forget to use our turn signal..... it does happen at times) the van goes (on its own) into emergency braking mode (when you are accelerating to highway speeds), causing us to almost CAUSE several Interstate accidents..... …
This is regarding the Collision Mitigation Braking System (CMBS) I will be driving on side streets around town (driving kids to school and daycare) and there will be no vehicle/obstacle near me/ in front of me and my van will flash on the dashboard "brake" and then it slams on the brake. This has happened at least 5-6 times as of todays date 5/20/25. There is no warning or reason for the car to brake like this. I have brought this to the Honda dealer two times now once I realized how serious this was. I was informed that since it isn't throwing a code there is nothing they can do. This is a serious safety risk not only to myself but to my children- this is a van so most people who drive this have small children. The last two incidents i was inches from being rear ended with my children in the car. …
