Filed Oct 28, 2026 · Driver assistance, Engine · SC

I am submitting this complaint regarding an ongoing safety concern with my 2021 Honda Accord. Multiple lights indicate engine system problems which includes, check engine light, car jerks at acceleration, seat sensor recall. I took my vehicle to multiple shops including the Honda Dealership. However, they were unsuccessful to identify the cause. Multiple problems such as Turbo, belt, fuel system problem constantly comes up. I have attempted to take my vehicle for the recall, which was scheduled, however after waiting 4hrs, the dealership stated they did not have the parts. I am concerned about the potential risk to myself, my daughter and my passengers and believe these issues warrant further investigation to help prevent possible accident or injury.

I am submitting this complaint regarding my 2021 Honda Accord because of a serious safety issue involving the turbocharger and fuel injector system. While driving on the highway, my vehicle experienced a failure related to the turbocharger and fuel injector system, which caused multiple warning sensors to activate and resulted in the vehicle suddenly losing power and becoming unable to continue driving. This unexpected failure forced my car to stop in the middle of the highway, placing me and other motorists at significant risk of a serious accident or fatality. A vehicle should not suddenly become inoperable while traveling at highway speeds due to a mechanical defect. This creates an extremely dangerous situation, especially in heavy traffic where other drivers may not have sufficient time to react. After researching this issue, I discovered that numerous other owners of 2021 Honda Accords have reported similar failures involving the fuel injectors and turbocharger. Given the number of reported incidents and the serious safety risks associated with these failures, I believe this represents a potential defect that warrants investigation. I respectfully request that the federal safety agency investigate this issue and require Honda to issue a safety recall if appropriate. No driver should have to experience a sudden loss of power that leaves them stranded in moving traffic due to an apparent vehicle defect.

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

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.

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.
