I have a 2023 Honda Odyssey van. The van has been modified for me to drive from my wheelchair. The steering wheel has been locking up eight times when driving. It won’t out let me go straight or turn left or right. This happens when I come to a stop. It happened twice when driving. The wheelchair modifications company southern mobility said they fixed many times but it still have the steering wheel lock up. Now they are telling me it’s the Honda’s fault. Honda said it’s the van modification fault. Honda said they can look at it for $150 a hour. I am very frustrated and very concerned.

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. Replacement of spool valve, valve cover gasket & valve was the fix. This may be a future recall. Car drives fine now after being repaired!

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. Honda has acted in bad-faith towards their customers since this defect impacts the vehicle's advanced safety features for which buyers incur additional expenses, endangering the lives of passengers. 6. Honda has acted in bad-faith towards their customers by designing a system that requires continuous and substantial expenditures without resolution because it is an engineering problem, i.e., the placement of the radar behind the large, thick plastic H emblem obstructs the radar. 7. I hereby ask that the NHTSA investigate this issue and order Honda to offer a solution in the form of a RECALL that permanently addresses the problem.

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. I did not because when I pull into a parking spot, I always have my foot on the brake and go in very slowly. As a brand-new van, I am very alarmed and very nervous it could happen again.

I wish to express my deep concern regarding the ongoing safety issues with the car I purchased in December 2022. Since April of the following year, I have repeatedly experienced heightened noise and vibration originating from the rear wheels. Despite numerous visits to the Honda 385 dealership and their assurance that they have documented and forwarded the concerns to Honda representatives for review, resolution has remained elusive. Regrettably, after an extended period of waiting, I was informed on February 26th, 2024, that the issue has been declined. This decision is profoundly troubling, particularly considering the potential safety implications. It is evident that a new car exhibiting such significant damage to the wheels, accompanied by pronounced noise and vibration, poses a serious safety hazard, especially during highway driving conditions. The persistent nature of these issues underscores the urgency of addressing them promptly and comprehensively. As a conscientious consumer, I cannot in good faith continue to operate a vehicle that may compromise the safety of myself, passengers, and other road users. I implore Honda and the dealership to prioritize the resolution of this matter with the utmost urgency, ensuring that the vehicle is restored to a safe and reliable condition. Furthermore, I urge for a thorough reevaluation of the safety concerns raised, recognizing the paramount importance of ensuring the integrity and reliability of the vehicles entrusted to consumers. It is my sincere hope that swift action will be taken to rectify these safety issues and restore confidence in the vehicle's performance and reliability.

Forward Collision Warning in conjunction with Emergency Braking have major safety issues that need to be addressed. 1st occurance: Driving through a construction zone through cones for lane realignment, van suddenly applied brakes in heavy traffic despite no obstacles in vans path. Vehicle quickly recovered. 2nd occurance: Driving on a dark street, van heavily applied brakes despite no obstacles. The braking occurred rapidly and van nearly came to a stop. Attempted to press harder on gas to override system with zero results. Had I been on a busier street, it would have resulted in a vehicle crash. This is a major safety issues that needs to be addressed by Honda with a recall.

While accelerating, well after a car far infront of me turned, the forward collision warning went off and automatically applied full breaks while I was accelerating slamming my legs into the dash. My kid has marks from his car seat. This is 3rd and most sever instance of this almost causing a severe crash behind me.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy.
