What 1,812 owners told NHTSA about the 2018 Honda Accord Plug In Hybrid

Vehicle: 2018 Honda Accord On [XXX], at approximately [XXX] PM, I was driving on [XXX] [XXX] at approximately 35 mph. The weather was clear and the road was dry. A vehicle ahead of me began turning into [XXX] N. My vehicle’s Collision Mitigation Braking System / automatic emergency braking system activated suddenly. The system made an audible warning sound, displayed a warning icon, and applied braking even though I did not believe there was a crash-imminent situation. There were vehicles behind me at the time, so the unexpected braking created a potential rear-end collision risk. The braking event also caused back pain, and I later experienced some stomach discomfort. I am concerned this was a false activation of the automatic emergency braking / Collision Mitigation Braking System. I am also concerned because the system reactivates after the vehicle is restarted, meaning I cannot reliably prevent another unexpected braking event from occurring. I am requesting that this be documented as a vehicle safety concern involving possible false activation of the automatic emergency braking system.

I was traveling down the road and I passed a bus that was in the right lane. I think when I reached the bus shadow that’s when the automatic brake warning came on and then my car went from 50 to 15mph instantly tossing everything in my car and hurting me neck.

My collision mitigation braking system is automatically braking on me with nothing in front of me going high rated speeds on the interstate. I have chronic migraines and neck issues that also have been being treated on a very consistent basis. I brought it in numerous times. I have appointment documents from dealership stating these issues, with no solution. Today it happened again severely and it was harsher than normal, scaring my 3 kids. I have had enough. Winter is coming and I am not gonna challenge black ice again. I have ongoing medical conditions being treated due to the repetitive whiplash.

Forward Collision Warning feature On 02/16/24 I was traveling east on I-630 at about 60 mph. While driving at that speed I saw a foreign object in my lane but I could not swerve in neither right or left lane as there were vehicles traveling in both lanes when my car hit the foreign object the object became lodged under the car dragging it at least 20 to 30 feet the car lost power myself and passenger had to push car out of road to shoulder to keep from getting killed as it had lost power and would not start. The Forward Collision Warning feature did not alert me of the object nor of the vehicle’s traveling ahead of me nor vehicles traveling in left and right lanes along side of me that I attempted to avoid hitting. I had previously filed a complaint about the warning lights and malfunctioning features on the car to dealership on 2019 2020 and 2021 I was told it could be a series of reasons why the warning lights are all on and the car features shut down even the car losing its power I was never able to get my car on the recall list for this I filed a complaint with Honda Manufacturer 2022 and was told that someone would be in touch but no one ever called I took the car back to dealership tech stated that the cracked windshield maybe the cause of the warning lights coming on so I got windshield , spark plugs, battery twice, replaced all for tires twice kept scheduled services up to par warning lights still on in-car still losing power in the middle of traffic on 01/20/24 I tried getting appt for fuel pump recall dealerships states they donot have the inventory to replace fuel pump I was told when Honda manufacturer contact dealerships giving the go ahead to repair I will l be contacted fast forward to 02/16/24 this is the result of none of features functioning especially the Forward Collision Warning feature my car now is at a loss of use it does not start the oil panel was damaged the radiator was crushed the sensor dislodged and body was damage to vehicle

After this car was repaired by the body shop, all the automatic systems in the car started flashing and no one could figure out why. It went to four different repair shops over several months, till finally they convinced me to purchase another vehicle when this one was going to be paid off in two months. This problem was well documented by several repair places , and ultimately since it was unrepairable I had to trade it in and got bottom dollar for a non-running car that I owned since the beginning and got screwed.

Automatic braking has randomly come on, causing harm or injury to those traveling in the vehicle. The few times that is has engaged has never been due to a close vehicle or object in front of the car.

Braking system caused my daughter to have an accident. My 2018 Honda Accord sport has been braking on its own for quite some time now. I attempted to turn off all safety features but somehow missed the braking system feature. The car will brake on its own with nothing in front of it. It will give beeping noises and flash “brake” on the dashboard. On 10/12/2022 my daughter was on the interstate, the roads were wet with heavy traffic. She called me saying that she had an accident. The officer stated that speeding played a part in causing the accident. My daughter said the car just started beeping and she noticed she was going to slow in traffic so she preceded to get in the right lane. Upon doing so she said that my car just started spinning and she took her foot off the gas and never applied pressure to the brakes. She ended up on the other side of the road hitting a guard rail. I feel like the braking system played a huge part in this accident.
