This has been reported one time before but the situation has gotten worse when driving at approximately 60ish miles per hour but it starts doing it about between 50 and 70 mph when driving and the car is using the regular engine not the EV section. You will randomly lose the ability to accelerate and you have to remove your foot from the gas let the engine slow and then re-accelerate now for the second time as I'm driving I lose the ability to accelerate at all and no matter what I do the car will slow almost every warning light on the dash comes on and there are 11 different warnings I've uploaded photos of a few I have a video though also and you lose complete power and ability to drive warning lights such as power steering problem emissions problem powertrain problem all of those are part of what turns on if you try to move the vehicle it will not move unless it is an EV mode and even then it only works for several feet but you can't get over a few miles per hour if you are on the highway like I was going 65 mph and there's traffic is extremely dangerous the only reason I was not hit was because I turn my emergency lights on and was able to maneuver my vehicle to the shoulder safely had I been in a more busy section of the road or had I been in an area where I could not get off the road I would have been hit by another vehicle. Honda has stated they can't find anything wrong with the vehicle but a quick Google search shows that this is a common issue and I have a video of the dash with all the warning lights should anyone need it as well as photos.

I hereby state that my 2021 Honda Accord has experienced major mechanical failures involving the transmission and head gasket. The vehicle began exhibiting mechanical issues including rough shifting, loss of power, and engine overheating. Upon inspection by a qualified automotive technician, it was determined that both the transmission and head gasket have failed prematurely. These failures have rendered the vehicle unsafe and inoperable, resulting in significant repair costs, loss of use, and financial hardship. The nature and timing of these failures suggest a possible manufacturing or design defect. This statement is submitted in support of a formal claim and potential legal action against the responsible parties for the defective condition of the vehicle.

Driving on Highway at approximately 65 Miles Per Hour using the Adaptive Cruise Control. Car in front of us took a right hand exit. My 2021 Honda Accord activated the Braking System and applied the brakes, so I stepped on the accelerator thinking it would override the braking system. It had no effect. There were cars behind me at the time and luckily nobody was injured. I looked this up on the internet and found that it is a reported issue. That is why I am contacting you. Very concerned about the safety of my family.

We were traveling on California Interstate 5 North. About 5 miles south of Junction 152 the car started malfunctioning. Suddenly there was acceleration beyond my control. I pushed the brake as hard as I could. It felt like the car was going to explode. Somehow miraculously the car landed on the shoulder of the freeway. It missed hitting any other cars or trucks. This was a rental car from Avis. I, my wife and another passenger came very close to death. For several minutes we were just shivering. We decided to slowly get back on the freeway with the hazard lights on. We didn’t was to be stranded in the middle of nowhere. At speeds of under 50 mph we eventually reached our destination. The next morning we again put the hazard lights on and took the car to Avis where we explained what happened. The agent gave us a replacement vehicle and said that they would put the malfunctioning vehicle out of circulation. Speaking to others we found out that Honda vehicles have had runaway acceleration.

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 Plug In Hybrid verdict →
