2019 Honda Accord acceleration problems

Filed Oct 12, 2026 · Acceleration · SC

The response to an accelerator input on this vehicle is unreasonably slow and has many times resulted in an unsafe condition. When applying a significant amount of throttle from a stop, or a slow speed, the driver expects the vehicle to respond immediately. I would like to note, that I am not referring to the vehicle's rate of acceleration. I am referring to how long it takes for the vehicle to begin accelerating. During several controlled tests, I applied significant throttle and timed the response to nearly 3s before the vehicle began to exhibit any significant acceleration. I believe this can be easily corrected as it is likely a delay built into the software.

I have keep regular maintenance up on my car. Recently all of the lights began flashing on the dashboard. I had oil changed, reset the battery, and all ignition coils. The lights came back on within a week. The car stalled while driving it and had to pull over inside of the highway, turn it off, wait a few minutes before turning it back on.

I have a 2019 Honda Accord Sport 1.5. I was driving on the freeway last week and my car did not allow me to accelerate anymore. Car went to an unsafe highway speed and it was hard to get to a shoulder where can safely stop. I felt my safety was compromised by this issue. All the warnings appeared on my dash and all the lights went on. No warnings prior to this problem. I am needing a new head gasket and repairs are estimated over 5K. I know there is a class action lawsuit against Honda because this issue is extremely common. I need help. I can’t afford these repairs and I depend on my car for transportation to work and child care daily. Please hole Honda accountable for this is very dangerous and very common.

My car started getting hot, began to overheat. I was on my way home on freeway. Second lane from slow lane. My car began to loose power, I could no longer excelerate. There was a big rig coming up behind me he was not slowing down as he got closer began honking I was trying to flag him that I could not move, as I was trying it started to go like 5 miles per hour where i began slowly to get over, cars in the other lane slowed down. Big rig went around me and avoided any collision. Thank God. I slowly made my way home on the streets with heater blasting. I towed my car to the dealer. I was told, my head gasket needed to be replaced, more than likely I would need a knew engine. Dealership said it was because when taken my car in for service I did not bring to the dealership. Cashier told me that there have been several incidents as mine.To my surprise I googled 2019 Honda Accord engine, and there were many with the same issue same car same year. Yet no recalls! I was lucky not to have been killed or have caused a multiple car collision. Are we waiting for someone to be killed to recall these engines. I missed several days of work, borrowed cars and rented a car to get back and forth to work not to mention the tramatic experience of a big rig coming at you honking on a FREEWAY. A week prior to this incident, my lights on the dashboard came on. I did call the dealership to set up an appointment. At that point they were no signs of overheating. I have taken my care in faithfully for oil changes where all fluids are checked, i was not told not once that any fluids were ever low, last visit was approx 5 months ago. I have called to have them send me all receipts. However in hindsight I do not need theses records as it has been proven by other people they have had the same experience. We are not talking about a faulty air conditioner we are speaking of an engine, in my case power failure. In the even records of oil changes and dealership diagnosis is required. I can email.

Car lost power on freeway, had the car towed to local Honda. After several hours of sitting at dealership and talking to several different employees. One employee comes back to tell me the head gasket was blown and needed repaired. And that this is a common issue he has been seeing in this make/model of car.

In the past 2 months my car starting having rough idle issues. As recommended by the dealership, I replaced the head gasket as they said it was leaking coolant into the cylinder causing the rough idle. Almost immediately after paying for this, the dashboard lit up like a Christmas tree with multiple warnings and the car went into limp mode, lost acceleration and would have been extremely dangerous had we been on the interstate or multi lane road. Took it back to the dealership, ran another diagnostic and determined the fuel injectors needed to be replaced. These repairs cost over $5,000. Recalls have already been put in place for models around this one and Honda should acknowledge these problems as it is wide spread.

I have taken my car to the Honda dealership on multiple occasions because my car has stopped accelerating while driving on the interstate. The car will flash the check engine light and completely stop accelerating while driving. I was first told it was the fuel pump that was recalled and waiting over a year on the recalled part and multiple times breaking down while driving they finally replaced the part. After the dealership replaced fuel pump I continued to have problems unfortunately happening more often and worse than before replacing the fuel pump. I was then told my car was misfiring and needing a tune up which would involve replacing all four coil packs and spark plugs. I replaced all of these recommended parts with no resolution to my problem. I have since be told by the dealership my car needs all four fuel injectors replaced after running the diagnostic tests. After doing research it seems to be a common problem with this make and model car. I can’t believe with as many cars with this same issue and the safety issues with completely stalling in the middle of traffic there are no recalls on these cars.
