Honda Accord loss of power problems

Filed Nov 1, 2026 · Engine, Fuel system · CA

A mechanic inspected or evaluated the vehicle and told me that the small fuel filter/strainer inside the fuel pump assembly may be causing the problem. The vehicle has intermittent starting difficulties, rough engine operation, and sudden loss of engine power while driving. The accelerator sometimes becomes unresponsive until I pull over, turn off the engine, and restart the vehicle. I am concerned about a possible fuel delivery system malfunction and the risk of losing power unexpectedly while driving. I am requesting an investigation into the fuel pump assembly and its internal filter.

Noticed that the engine temperature was slightly higher normal (went to 5 bars when always at 4) I checked and the fan was running properly and had coolant in the overflow tank. I took it to the Honda dealer, and they found that the head gasket failed and the fluid inside the radiator leaked into the cylinders. My 2018 Honda has the 2.0T engine with 126,875 miles. Honda acknowledges this design flaw on their 1.5T and 2.0 non-turbo engines but wouldn't cover my 2.0T. This 2.0T from my research is about 80-100 units of the 1,115,384 accords sold in the US 2018-2022 10th gen. The 2.0T has the same design flaw as the other two engines but Honda wont cover them. Moreover, I asked for 50% good will coverage from Honda and was flat out told no after waiting for 4 weeks to get this decision on a known mechanical engine flaw that could be a safety issue, Eg. fire or loss of power on a highway that can get someone hurt or killed.

"While driving, the front driver's side driveshaft snapped due to an active safety recall. The vehicle was towed to a dealership for the recall repair. Immediately after the new driveshaft was installed, the car began shaking violently under braking and driving. The dealership inspected it and diagnosed a broken tie rod caused by the snapping driveshaft, but the dealer is refusing to cover the consequential damage or towing reimbursement, leaving an unsafe vehicle undriveable on their lot the incident happened "While stopped at a traffic light at [XXX] and [XXX] taking a left turn, I pressed the gas to go through the intersection. The vehicle made a loud clunk sound and completely lost all drive power (driveshaft snapped). I had to manually push the car ('Flintstone it') out of the intersection to safety.". After losing all power during a left turn at [XXX] and [XXX], I coasted down and up a hill. Because the broken axle severed the transmission connection, the vehicle would not hold in Park, causing it to roll and end up facing the wrong direction on the wrong side of the street while waiting for a tow. The car was subsequently towed to the dealership for the recall repair." INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle: 2021 Honda Accord Sport Subject: Intermittent Electrical Malfunctions, Multiple Safety Warnings, and Loss of Acceleration I am reporting ongoing safety concerns involving my 2021 Honda Accord Sport. On multiple occasions, my vehicle has displayed several dashboard warnings, including brake system, electric parking brake, vehicle stability assist, hill-start assist, adaptive cruise control, and electric power steering warnings. These warnings have appeared intermittently in the past and sometimes disappeared on their own. On October 18, 2026, while traveling on the highway at approximately 65 mph, these warnings had already been displayed for approximately 30 minutes to an hour when my vehicle suddenly began struggling to accelerate. Despite pressing the accelerator, the vehicle continued losing speed, and the RPM gauge remained around 2,000 RPM. It felt as though something was holding the vehicle back. After several moments, the vehicle suddenly regained power, accelerated, and the RPM increased. This was particularly concerning because I was traveling at highway speed. I also experienced electrical problems with the interior lights. While the vehicle was running, neither the automatic interior lights nor the overhead lights near the rearview mirror would turn on. They remained inoperative after I turned off the vehicle. Later, the lights began working again, but I noticed the right overhead light fading while the left remained illuminated. The battery was replaced earlier this year, in 2026. I am concerned that these intermittent malfunctions could result in a sudden loss of power or failure of important vehicle safety systems while driving. I am requesting that these problems be documented and investigated for a potential safety defect or recall. I have photographs of the dashboard warnings available as supporting documentation.

Air conditioning failure: The A/C was blowing warm air on the first day of ownership. • Cooling system failure: The vehicle subsequently experienced overheating issues and left me stranded. • Coolant loss and radiator leak: All Star Honda identified a leaking radiator and found the cooling system out of coolant. • Failed thermostat: A failed thermostat was identified during the diagnostic and repair process. • Stop-leak substance found in the cooling system: Stop-leak material was observed in the cooling system. I have concerns about why it was present and not disclosed initially • Water pump and cooling-system repairs: Repairs included work on the thermostat and water pump, followed by radiator replacement and a coolant flush. • Continued overheating concerns: Despite repairs, I continued experiencing overheating alerts. • Engine performance problems: The vehicle experienced a loss of power, with a reported inability to maintain speeds above approximately 60 mph during one incident. • Check-engine warning: A prior repair-order history documented a blinking malfunction indicator light during a driving incident. • Diagnostic trouble codes: Codes P2601 and P272D were subsequently reported. • Potential head-gasket concerns: The possibility of a head-gasket problem has been raised during the ongoing dispute. Honda has referenced a multi-model cylinder-head-gasket warranty extension, but I have not received approval for coverage on my vehicle. • Warranty denial: Honda corporate has declined to approve the requested warranty coverage. Despite the repeated problems, diagnostic visits, and repair attempts, I am still dealing with the consequences of purchasing a vehicle that has not provided the reliable transportation I paid for. I have spent time and money trying to get answers, and I have been left facing the financial burden of a vehicle that I cannot confidently depend on. I am sharing this timeline because consumers deserve trans

While driving, the front drive shaft (axle) suddenly snapped completely in half without warning. This caused an immediate loss of power to the wheels, creating a hazardous driving situation and leaving the vehicle stranded. Upon inspection, the drive shaft broke directly beneath the rubber dynamic damper (vibration damper). The area under the rubber ring shows heavy rust and corrosion. Furthermore, the unbroken drive shaft on the opposite side of the vehicle shows a heavily dry-rotted rubber dynamic damper ring, raising immediate concerns that it will fail next. This failure matches the physical description of the defect found in the federal safety agency Recall Number 20V‑769 (Manufacturer Recall Code OM2, corresponding to Honda Service Bulletin 20-125). Under that safety campaign, Honda states that moisture and road salt seep under the dynamic damper, causing hidden corrosion that ultimately breaks the axle. However, Honda has restricted the scope of Recall 20V‑769 exclusively to vehicles equipped with Continuously Variable Transmissions (CVT). Because my vehicle has a 6-speed manual transmission, my VIN is excluded from coverage. Despite having a different transmission, my vehicle was built with factory axles that suffered the exact same corrosion failure in the exact same location. The exclusion of manual transmission vehicles from this recall leaves drivers exposed to a known safety hazard. I request that the federal safety agency review this failure on manual transmission models to determine if the recall population needs to be expanded.

I am reporting repeated, unpredictable loss of engine power and propulsion in my 2019 Honda Accord Touring 2.0T (approximately 146,000 miles). The exact cause remains UNKNOWN. On XXX, while driving on [XXX] near [XXX], my vehicle suddenly lost acceleration at highway speeds and eventually stalled. The vehicle repeatedly lost power, experienced crank-no-start conditions, and at one point could barely maintain 10 mph. I was stranded and had to have the vehicle transported to a Honda dealership in [XXX]. Diagnostic code P0087 (Fuel Rail/System Pressure Too Low) was recorded multiple times, including at 70–74 mph. Numerous warnings appeared, including emissions, brake system, electric power steering, stability assist, adaptive cruise control, collision mitigation, and road departure mitigation. The unpredictable loss of propulsion creates a serious collision risk, especially on highways and in traffic. The Honda dealership initially could not reproduce the failure. After replacing the spark plugs at my expense, the vehicle was returned to me. Approximately 23 miles later, the malfunction returned, and I immediately brought the vehicle back without clearing any codes. Honda subsequently diagnosed and replaced the high-pressure fuel pump at my expense, but the loss-of-power issue continued. The vehicle previously received Honda’s in-tank fuel pump safety recall repair in May 2025. Despite that recall remedy and subsequent repairs, the vehicle continues to malfunction. The exact cause remains undetermined. The vehicle has been inspected by an authorized Honda dealership. Repair records and diagnostic information are available, and the vehicle can be made available for inspection upon request. I am requesting an investigation into this recurring safety-related loss of propulsion. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
