Jan 3, 2026Transmission & drivetrain

Complete loss of power on acceleration. Car goes limp while driving on highway or a 50 mph street - very dangerous to have loss of power when other cars are driving fast too. We have replaced the spark plugs, coils, and fuel injectors. That was a waste of time and money bc the same problem existing- loss of power again! Turns out, it’s bc the Head gasket has a design flaw - deep grooves between the cylinder heads and head bolts that are not strong or tight enough. I have lost all trust for Honda bc this has not been issued as a recall. After quick online research- Everyone is having the same issue who has these models, this needs to be a safety recall bc Honda created a faulty head gasket design. This car is not safe bc the head gasket design, and I’m making payments on a car that I can’t even drive. Unethical for Honda to not take accountability for this! I’m driving my 03 Toyota that has over 300k miles is more reliable than this 2020 Honda - paying for a car I can’t drive makes me despise Honda for not issuing this recall.

The contact owns a 2020 Honda Accord. The contact stated that when attempting to start the vehicle, it would rev up and take an extended 15-second start before starting. The vehicle was taken to the dealer, who was not able to duplicate the issue; however, did presume that a defective fuel system caused the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 48,000.

Sticky steering wheel at highway speed 70mph and when you put enough force to make it turn it jerks and you have to over correct it and go the other way to maintain in the middle lane on the highway. Takes about 10-15miles to start doing it but does not go away at all once it starts. Happens everytime on the highway

I would like to report a known issue with the Honda Accord Sport 1.5t. My head gasket went out Aug. 2024 with about 100,000 miles on the dashboard. The cost to change it was about 4100. My Turbo Charger is now out Dec. 2025, and they are quoting me about 2100 before taxes. The dealership did advise that there is a known issue with the head gasket going out prematurely due to a default with the engine. They also advised that the turbo charger normally goes out after the head gasket is replaced. Please work on having the engine recalled. This is awful. After researching this issue, I see thousands of others are having the same issue. Best regards, Yvette J.

While driving my 2020 Honda Accord Hybrid, VIN [XXX] , the car would start exhibiting rough engine feels, and all of the dashboard lights would come on. The car would lose power at highway speeds, and I’d have to pull over to turn the car off and on. When checking on OBDII meter, getting P0301 codes. I have replaced the coils and plugs twice and still not better. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While I was driving on the highway, the brakes of my car suddenly were violently activated and I had not touched the brakes. If there had been a car behind me, it would have been a major rear end collision. It was over quickly and I accelerated back to the normal speed. I talked to the Honda Service Mgr where I purchased the car and he said he was unaware of the problem although I see that that nearly 3 million Hondas have experienced this issue.

A supplemental restraint message is occasionally flashing on my dashboard

NHTSA ODI 11705104

Dec 11, 2025

It is unknown what system failed. While coasting to slow for the stopped car in front of me, the car began aggressively accelerating without warning. Adaptive and standard cruise control were both off. Lane keep assist and road departure were also switched off. Due to the slick nature of the road, the acceleration left me traveling far too fast with little space to stop. After sliding to a stop, I was within a foot from the car in front of me. This failure very nearly caused an at-fault accident which there was nothing more I could do. Note that this happened roughly 40 mins into a drive, which was otherwise uneventful. No warning lights were present before, during, or after the issue. This car has been having phantom braking issues and power loss issues consistently since March and has spent significant time in Honda's hands for this issue. The vehicle has come to a near stop on the highway from the previous braking issues and has lost power, stranding me in traffic on a highway. It is suspected that the same system failure that caused those issues has come back up again. To date, thousands have been spent on repair "guesses" and tow bills with no end in sight to these safety issues. This vehicle has become a liability and, as a result, inspections are strongly encouraged. I have included photos of the floor mats as they were at the time, properly secured and not near either pedal.

I had just left my job in Albany and was headed to the Latham area, while merging into traffic on I-90 West my 2020 Honda Accord EX-L started to rattle and slow down, numerous lights illuminated simultaneously on my dashboard. I immediately pulled off the north shoulder and restarted my vehicle to no avail, the dashboard lights were still lit and my vehicles speed and steering were compromised. My safety was put at risk due to the immediate issues as previously described while in heavy traffic, I could have easily been involved in an accident due this issue. The system Keeler Honda advised me that had failed was allegedly the head gasket leaking coolant into the engine by means of cylinder four. I was later informed by Keeler that this is a common issue with the accord 1.5 L turbo engines. The problem has been verified by Keeler Honda. There was no prior warning light on my dash that would have indicated there was an issue with my vehicle, the lights only all appeared once the incident had occurred.

Driving on a clear road on a clear day with no car in front of me, the brake warning flashed and then the car braked on its own. There was NO reason for the warning or for the car to brake on its own. Automatic breaking isn’t even a feature on this car.

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 2020 Honda Accord Fhev verdict →
