Fuel pressure dropped and car stalled.
My vehicle is currently suffering a failed head gasket. I was alerted about this issue from local mechanics and friends way before it actually happened. I took it to services and regular maintenance even more frequently after that. However, it still failed no matter what. I took it to the dealership, they even admitted that this is a known problem for this generation of vehicle. They still proceeded to ask nearly $7000 to fix it, saying that even though this is a known issue, there was no recalls on the vehicles so they could not waive or deduct the fees.
I am writing to file a complaint on the service that was provided at vann york Honda. On February 17, 2026, I was returning home from work and my car had a hard idle at start up. I was able to drive it home without issue. The next day, February 18, I got in my car and I had another hard idle start with many check engine codes appearing on the dashboard. I drove it to vann york Honda in high point, north carolina for service. I was told it was a faulty fuel injector causing the problem and that it needed to be replaced. I left the car there over night and paid for the service; approximately $3,000. I got the car back on February 19. On February 20, I again had a rough idle on start up. I brought the car back to vann york Honda and advised them that I was experiencing the same issue as before. The mechanic brought it to the back and advised me that he could not find anything wrong with the vehicle and that it is running fine. I expressed my concerns with the vehicle and he stated that without a error code or check engine light being on, it would be difficult to diagnose. The technician and the advisor said to keep driving it until a light comes on saying there is a problem since they could not find an issue. In the following 2 weeks, I had regular rough idles on start up and the fuel efficiency dropped approximately 6 miles per gallon. When I filled the car with gas, the fuel range dropped from 540 to 370. When I called about that issue, they said they reset the computer when performing the previous service on the vehicle and it is taking time for the computer to "learn" the car again. On March 6, I brought the vehicle back to vann york Honda due to many check engine codes appearing on the dashboard. On the way to vann york, the service advisor called me and stated that she would be reaching out to Honda corporate to see about Honda paying for some of the cost of this service. My wife and I drove into the service bay and I spoke with the service adviso.
I turned my car on and it didn't want to crank up. Once it did crank up every warning light came on. My son ran the code and p00087 came up. I tried to drive my car in my parking lot and it kept stalling like it was going to cut off. Now I drove my car earlier in the day and didn't have any problems. It wasn't until after my car sat throughout the day when this took place. I know it's a recall for fuel pump issues but my car isn't included.
All lights on dash. Fuel injectors need replacing at 35000 miles.
Vehicle accelerated on its own and propelled the vehicle over a curb and into a building. This occured even though the gear shift was in the park position. My grandchild and I were thrown forward as vehicle hit the building. Vehicle has not been inspected since incident occurred just yesterday, 11/20/2025. No warnings preceded the incident,.
Car will drive fine , then all of a sudden it shuts completely off on the highway which is a major safety concern. All the lights will pop on in the dash board without any warning. Car will act as if it doesn’t want to pick up speed then after about 10-15 mins starts driving fine . This is my second time contacting you all regarding the same issues . Honda needs to definitely do a recall ASAP this is not safe at all to be driving around like this . Alot of customers driving 2018-2022 Honda Accords have been having the same exact issues . .
Hello, I have a 2021 Honda Accord sport 2. 0t engine. The engine has a 2. 0 liter turbo. I have had to replace two fuel pumps, which were covered my extended warranty. Another issue that I had to repair, and one that has not fully been resolved is the head gasket. I have been losing coolant at an alarming rate. Every two weeks I have to fill up coolant. I had the head gasket repaired at a Honda dealership, and this is currently being diagnosed by another Honda dealership, as I do not want to deal with the Honda dealership in cedar rapids, iowa. Currently, a Honda dealership in iowa city, iowa is handling the issue, but the head gasket along with the cylinder head were originally repaired in October 2025. Since December 2025, I have been losing coolant on a regular basis. I still have 5,000 miles left on my extended warranty, but there have been many owners who have had their head gasket replaced, or are needing replacement, and Honda refuses to acknowledge that there is a manufacturing defect with the engine. The 2. 0 liter turbo engine has a major design flaw with it's cooling passages, and Honda has yet to come up with a resolution. Having an engine overheat is a major safety concern! the current dealership is driving my vehicle on a regular basis, in fact the service advisor is driving it to work and back home (35 miles each way) to replicate the problem. At this point, a recall should be issued by Honda, as there is currently a class action lawsuit that has occurred in the state of California.
Note the malfunction described below is currently under recall for multiple Honda models but has not yet been recalled for the 2021accord sport se. Please add to the list!! I was driving when warning lights flashed, car started to slow down and then shut off. I repeatedly tried to start my vehicle which was unsuccessful. I took my car to Honda and had the low pressure fuel pump changed on 8-1-2024. Today 2-5-2025, it happened again. Seems to be the high pressure fuel pump this time. I did research and this seems to be an issue with a lot of Hondas. Please research and add this to this list. Not to mention my 2021 Accord only has 70k miles.
Note: the item / malfunction described below is currently under recall for multiple Honda models but has not yet been recalled for the 2021 Accord sport 2. 0t. Please add this model to the recall list!!! I had been driving on the interstate for about 30 minutes on Thursday, 11/7, when suddenly seven of the warning lights flashed in succession on my vehicle, including braking system warnings, emission system warnings, and tire pressure system warmings. I pulled to the side of the road, quite concerned. I called the dealership. The service professional thought it might be the radar on the front camera causing an electrical system malfunction. I was advised by the service technician to drive slowly (about 55mph) and come to the dealership (about an hour away). Upon inspection by the dealer, it was determined that the high-pressure fuel pump in the engine was defective. I did a bit of research: this is the same part that is currently under recall for 720,000 vehicles (2023–2024 Honda Accord and Accord hybrid, 2025 Honda civic sedan and civic sedan hybrid, and 2023–2025 Honda cr-v hybrid). Please add the Honda Accord sport 2. 0 t, 2019-2022 to the recall list for this issue!.
@ 96,970 miles, (2021 Honda Accord hybrid) when getting on the freeway and accelerating to catch up with traffic, the car began sputtering, the check engine light flashed, the accelerator stopped working and I had to get it to the shoulder of the freeway immediately. The car sputtered and shook. I turned the car off, let it sit. I tried re-starting it and it started fine, no check engine light. I drove it slow off the freeway and to my home close by. I got it to the dealer. The service rep said he had never heard of this issue although it does appear on Honda forums. He said no codes showed and decided it needed a cylinder adjustment and then decided it also needed a new (refurbished) transmission. It was in the shop for weeks. I've tried warming the car up longer and using more expensive gas. Issue continues to happen. I called an made an appointment at the dealer for first available date. Today I had it checked for codes again from a different mechanic and the mechanic said it has no codes - at all. Fluids all perfect, no issues with coolant levels. All maintenance has been completed on schedule. I did video tape my dash when it happened Wednesday, on i80, 3/5/25 12:12pm.
I have experienced 2-3 sec hesitation upon accelerating. This hesitation occurs occasionally usually when turning and the is stopped or moving slowly. When it has happened I have experienced threatening safety situations particularly when making turns when crossing oncoming traffic such as when making a left 90 degree turn at a stop light with oncoming traffic in the lane I am crossing or if I have to make a quick acceleration to avoid a rapidly threatening safety situation.
