This Honda Accord Sport SE has had electrical problems from the day I received the vehicle. Every time I went for an oil change at Bommarito Honda I mentioned it to them and they said “yeah the new Hondas do tend to hand a lot of those electrical problems” so with this the problems continued to get worse. Sometimes the buttons do not work, sometimes they do, sometimes the lights don’t work and sometimes they do and sometimes the safety features and break system automated itself. I have slammed my head on the steering wheel on multiple occasions. I believe this needs to be looked into because the malfunction of the car falsely reports danger and caused an accident. Yes every time it malfunctions it flashes briefly and so quickly on the screen .

I was driving northbound in on I15 in Salt Lake City when a Home Depot Bucket blew into my lane. I slowed down to change lanes when the Collision Mitigation Braking System (CMBS) deployed without warning, bringing my car to an almost stop causing a semi tractor trailer to hit me from behind.

I was traveling on interstate 10 going around 50mph with a safe distance from the traffic in front of me. The car in front of me did break but then sped off immediately. My car's automatic emergency breaking system engaged very aggressively and unnecessarily (a front end impact was not imminent if my car had not braked). I tried to accelerate but I had no control over it. The sudden breaking caused my car to slow so rapidly that the freightliner behind me did not have time to react, causing him to rear end my car. The car was totaled as a result. I have front and rear dash camera footage showing all of this. ***I marked a document as the police report to proceed but I do not have a copy of the police report. This is not provided unless ordered***

Honda Accord multi point serviced July 2nd at Hendricks Honda Easley SC. Immediately after I was driving on Haywood Rd. Greenville SC when my vehicle slammed on brakes for no reason. There was no car, animal, pedestrian or debris in road to cause to happen. As a result I experienced whip lash and was seen by a doctor and therapist July 5th. This has caused me to be afraid to drive my own car plus miss work plus enjoy my July 4th. I have reported this to Honda Motor Company and I also returned to Hendricks Honda to have a diagnostic test performed but all they did was put 20 miles on my vehicle and said I would have to bring it in and leave it for 3 - 4 hours. WHY? If you truly checked it out today I don't feel I need to return for them to just tell me anything. I really feel like they wasted time doing nothing today. There diagnostic was just driving my vehicle and adding unnecessary miles.

Jul 2, 2022Speed controlDriver assistanceCrash

Car moving slowly and suddenly races and speeds UP. Hard to STOP it. Has happened twice, 8 to 10 Months apart.. First time was on a small driveway. Was able to STOP CAR , with no damages. 2nd occurrence i was pulling into a parking Space. Foot not on gas or brake and again the CAR accelerated. This Time the CAR hit a handicapped parking sign and pushed it over. The sign stopped the CAR with Assistance from me. There was a small drop in front of the CAR and a tree 10-15 Feet in front of the Hill. The passenger in my CAR would have been in severe trouble had I not gotten the CAR stopped. My husband thought i may have somehow activated the cruise control. But i was going less than 20 miles per hour each time. This could be a deadly problem if a Child or Someone Crossed in front of me.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Honda Accord Fhev verdict →
