Over the summer when our Honda odyssey was only a couple months old (we had bought it brand new) my 7 year old son ended up with the seatbelt in the back passenger seat wrapped around his neck! He was playing with the seatbelt and somehow got it around his neck. I was driving and his siblings told me what was happening. I of course quickly pulled over into a parking lot and I couldn’t believe how tight it was wrapped around his neck in such a short period of time! As I was trying to loosen it it just kept getting tighter and tighter. My daughter ran into a Taco Bell and asked them for scissors and the workers couldn’t believe the situation we were in said there’s no time to even call 911 they had to cut him lose. So we had to cut the seatbelt with scissors to save his life as it was super tight on his neck. It was an awful experience I never could have imagined happening. I see that this seatbelt locking system is placed on new cars and I think it’s so dangerous. I now have no seatbelt on the back seat of my car as it had to be cut off and the dealership said it’s thousands to be replaced. All they said was I’m sorry that happened to you. I think it’s awful cars are made this way. My son could have died.

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.

Mid November 2023, at 9 am, between Livermore and Pleasanton, California, USA, while driving my wife's 7000 miles Honda Odyssey Sport 2023 sunroof glass imploded. An extremely loud bang noise followed by a rain of micro crystals over my head, driver, passenger and back places. My right ear was numbed and when I could manage to stop, I got pinched by the micro crystals everywhere, while my sunroof pieces of glass kept falling over me. Immediately I filed a claim with NHTSA (which didn't received any email or case # after a long call explaining what happened); also visited the dealership who sent me home and had been giving me excuses during 3 months already. Supposedly the replacement part is not available and not covered by warranty. This is unacceptable for an international brand like Honda. I've owned Honda cars for years and my family too, never thought this could happen to me while driven our best Honda at home. A sunroof SHOULD be laminated NOT tempered-only, and Honda should address their sunroofs defects asap. This is such a risky situation and I know this had happened before to many persons driving Hondas and Acuras. Please DO SOMETHING ABOUT IT NOW before somebody dies!

The vehicle makes a whistling sound form the front of the vehicle, while on a road trip the windshield got foggy and the defroster was not able to clear the windshield due to what I believe is an air leak from the windshield, that’s also causing the whistling.

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.

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..... because of this SAFETY feature. These vans are very unsafe.

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. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.
