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

The vehicle had a very violent shift (perhaps it was turbo lag related?) at low speed (under 20 miles per hour - typically, this happens in a parking lot or the like as you slowly drive away). In the past, this had been mentioned to the dealer, numerous times, who claimed that the issue is not reproducible. However, during the visit on 12/06/2022, dealer mechanic(s) claimed that they did witness the issue and the fix the performed the following (per dealer's notes): "reset TCM and Batter cable reset." after which (the dealer notes state): "Let the customer know that the trans will adapt to driving habits within 200 miles. If the customer drives hard, the transmission will learn hard to shift hard etc..." The second statement is nonsensical, since, most of the time the transmission shifts relatively fine, regardless of the driving pattern (i.e. hard, mellow, etc.) and the issue happens intermittently (every so many hundreds miles driven), at very low speeds with very little accelerator input, which indicates more of a software issue (and, possibly a mechanical design defect, coupled with the SW issue). Again, Honda has refused to properly troubleshoot and address the issue. There are now other customers with, what sound like, a very similar problem: [XXX] And, just as with my vehicle, other dealers are claiming "there is no issue" and Honda has ignored the issues. Honda has a history of transmission problems from the 2000s and it's really worrying that they might be repeating that pattern with 2018-on models: [XXX] While I am noting the issue at this mileage, there are numerous other instances of where the same problem occurred. The violent manner in which these shifts happen, makes one wonder how much mechanical damage is being done to the transmission and if a recall should be issued.

My car ran good up until July 29, 2023. There was a slight tornado and lots of rain when I parked the car it was fine hour later it began to stall and became undriveable. I called my insurance company Progressive and called Honda of Manchester and Progressive had the car towed to Honda. They came back with the diagnosis of my HeadGaskit needs to be replaced my fuel injectors are miss firing and the piston rings needs to be replaced. I have 84,998 miles on the car and all of the maintenance records are up to date. Honda gave me a price of $4,800+ to have it fixed. Where I’m concerned at is how can these many problems happen at one time and I had know warning signs it just stopped running all of a sudden.

NHTSA ODI 11540978

I have been dealing with the check engine light codes p0172c & p219c. Honda inspected my vehicle and said the problem is that my car is running too rich and the fuel injectors are bad but they say i cant really do anything because the fuel injectors are on backorder but really they are discontinued and they are unsure when theyll comeback. Im concerned for my safety and for others on the road because the p219c code is commonly associated with a leaky head gasket, and after speaking to several third party mechanics theyve all said they have been getting others with the same problem and the fuel injector isnt the actual problem, its the head gasket. which means unfortunately my head gasket could blow any moment im driving my car which i NEED to do because i NEED to work. I travel at least 40 miles a day in houston traffic and im very worried about the potential damages i can cause should my head gasket blow while im driving in rush hour on the highway. I had no other kind of warning for this besides the check engine light and its been on for the past 4 weeks.

Engine loss power on and off and start going slow

NHTSA ODI 11534025

There has been a series of constant issues with this model and each issue has been brought to a certified Honda dealership and was supposedly "fixed" engine code P0300 (random/multiple cylinder misfire),P2651 B rocker arm Actuator system, P0087 Fuel Rail/system pressure, P0304,P0303 cylinder 3 and 4 misfire, engine temperature always above normal. These issues on multiple situations has put my safety and the safety of others at the highest risk. The motor vehicle due to these issues randomly would lose power to the point where stepping on the gas doesn't not accelerate the car, forcing me to stop in the middle of the highway having other vehicles stop suddenly and swerve around me with children in the vehicle. Another occasion going up a hill the car beings to stutter losing power resulting to the car shutting off, forcing me engage These reoccurring issues have also randomly caused the vehicle to not start. Multiple warning signs are lit across the dashboard. These occurrence are random with no warning sign The vehicle has been brought to the same dealership numerous times claiming each issue was fixed but within a few weeks more issues came. The last visit i was told as a "solution" i need to buy a new engine out of pocket, unacceptable for a Honda engine with 64000 miles on it. This oil dilution issue need a proper answer before someone is serious injured.

You lose power while driving than it stalls to about 20 mph Emmission warning lights come on. After cool down the car will drive normal speed again for a short time before it repeats itself driving 20 mph with emission warning light coming on. It is a very hazardous condition and dealerships can’t figure anything out. We have spent 1600.00 on fuel ejectors And car still doing the same thing. Next morning my husband drive it to work and was put in a hazardous condition.

The contact owns a 2018 Honda Accord. The contact stated that in April of 2021 the vehicle was taken to a dealer for an unknown recall related to the BCM. Months later, the contact parked her vehicle in the driveway and walked around it to retrieve her trash can, when she turned around it was discovered that the vehicle was rolling causing the front to crash into her against the garage wall. There were no warning lights illuminated. The contact sustained a pelvic bone injury and was transported to the hospital for medical treatment. A police report was filed. The vehicle was not diagnosed or repaired by a dealer. The manufacturer had not been informed of the failure. The failure mileage was approximately 30,000.

All warning indicator lights came on and I took car to a Certified Auto Mechanic who said it was caused by the fuel pump problems surrounding Honda cars. Said it affected the fuel injectors (mis-fire) and I should take it to Honda dealer for fix. Honda dealer said this VIN of my 2018 Honda is not on the recall. I asked about being covered by the 5 year power train warranty and was told that this did not fall under that warranty. The auto mechanic said he would have to charge around $2000 to replace the fuel injector (1), but the others would probably go bad unless everything (Pump and injectors) were replaced. There over 500 complaints with NHTSA on this year model and over 200 of those are similar problems that match prior recalls for same model and year but different vin numbers. The reports from Honda to NHTSA regarding selected "recall" units does not prevent other problems identified due to Indian defective parts surrounding the fuel pump problems. If I read all the details correctly only hundreds of just 10,000 recalls have been completed. Why would Honda/NHTSA not want to include the few other hundred that may be present to prevent accidents and uphold the Honda reputation of quality?

On 3 separate occasions my Honda Accord 1.5T has lost power while driving in traffic. All of the warning lights came on, and I could not go over 10 mph. Fortunately i was able to turn onto a side street each time. I turned off the the engine and after a few minutes restarted...only once was I able to regain power and drive home with normal power. My car went to the dealership each time, and they have told me they cannot duplicate the issue. And now the dealership has had my vehicle for almost 2 months. The service agent said he has never seen anything like it, and when I mentioned specific articles about the turbocharged 1.5 engine online, he discounted them saying, "anyone can write stuff on the internet". Honda dealership and Honda Corporate has no solutions, other than just live with it. A car slowing down in heavy traffic or on the expressway is a major accident waiting to happen, and Honda doesn't seem to care.

All the systems in the Picture failed.. I noticed my reading lamps don't work and middle brake light stays on dim when these warning lightscome on.... and the car loses power on the road It will slow down like its braking and won't accelerate. if there is ever a tractor trailer behind me I'm afraid it will hit me... when shutting down the car and restart within 30-50miles warnings lights come back on..
