Transmission & Drivetrain complaints by model year
City street driving speed < 35-40 mph, engine began rough idling at stop light after traveling just 1/8 mile. After driving less than 1 mile on level ground, engine slowed and would not accelerate above 20 mph. After another mile or so, increasing uphill grade caused speed to slow to 12-14 mph. Stepping on gas caused car to slow down even more, with shaking and jerky stop-start of vehicle. Maintaining 10-12 mph permitted vehicle to continue uphill climb for a few more miles so I could reach home. Downhill coasting was smooth with no gas pedal acceleration. Overnight parked in garage, and no problems driving vehicle to local independent auto mechanic. They were able to duplicate problem after 2 days and multiple test drives. Diagnosed permanent and temporary engine codes: misfires of cylinders 1 and 4 with ignition coil malfunction, misfires of cylinders 1, 2, 4, and random misfires. Also permanent codes: antilock brake ECM Failure, electric power steering vehicle stability assist System Malfunction, electric servo brake electric power train System Malfunction. Mechanic removed coils and spark plugs, found cylinder 4 has moisture. Coils, plugs cleaned and re-installed. Honda Dealer unable to duplicate problem after 3 days.
NHTSA complaint #11720056 — an unverified report by a vehicle owner.
The car loses power. It starts as a misfire on cylinder 2 (P0302 code) and the engine starts to shutdown (or goes into a safe mode with no power). The result is loss of speed which creates a safety hazard especially on highways. This has happened multiple times and the car has been in the shop 4 times for this issue. We have to pull off the road, turn the car off, sit for a minute and restart the car. It will then run ok. This has happened during acceleration and when just trying to keep speed on an incline. The dealership has not been able to identify an issue. The head gasket was replaced in April 2025 because they thought there was a pin hole that was causing oil to push into the cylinder. The misfire continued to happen. It was in the shop on October 2025 and they found nothing wrong with the spark plug, induction coils, gas feed. Therefore no understanding of the root cause.
NHTSA complaint #11693248 — an unverified report by a vehicle owner.
While driving ~70 mph on highway on adaptive cruise control, the car suddenly LOST ALL POWER/ACCELERATION, including POWER STEERING and ALL WARNING LIGHTS FLASHED ON THE DASHBOARD. I recalled some were BREAK SYSTEM, ACC, ABCS, CHECK ENGINE, POWER, TPMS...etc. Essentially any warning light Accord has was flashing. The car slowed with no power steering, I managed to parked on the shoulder and turned on hazard light. This is extremely dangerous as the highway traffic was extremely heavy. After I parked, I pressed the ENGINE START/STOP button thinking I needed to "turn it off" but the car already had lost power at that point anyway. After pressing it a couple times, the car restarted and I drove to the dealer with one error message remaining on the dashboard - "Emission system problem. Power may be reduced. See you dealer." and the CHECK ENGINE light was on.
NHTSA complaint #11691682 — an unverified report by a vehicle owner.
Component/System that failed or malfunctioned: Power Train: automatic transmission internal (CVT). The vehicle stops responding to acceleration, remains static while the engine continues at high revolutions, without generating forward movement. The component is available for inspection upon request. How safety was put at risk: The incident occurred while driving on the highway. By losing acceleration power and not being able to maintain the required speed according to traffic laws, I was at risk of being struck by other vehicles traveling at normal highway speed. This situation posed an immediate danger to both myself and other drivers. Problem reproduction/confirmation: The dealership inspected the vehicle and informed me that, at this time, there is no safety bulletin related to my unit. Inspection by third parties: I have scheduled an appointment with the dealership for September 5, 2025, where a more detailed evaluation of the problem is expected to be performed. Warning signs or prior symptoms: When the failure occurs, several warning lights illuminate on the dashboard and then turn off. Timeline / first occurrence: The failure occurred on August 14, 2025, at 9,215 miles. Related campaign reference: There is an existing NHTSA recall campaign for the same vehicle model: NHTSA Campaign ID: 23V588000

Vehicle Power Loss and System Malfunctions I am writing to formally express my concern regarding a recurring and potentially dangerous issue with my vehicle, 2023 Honda Accord Hybrid. Twice while driving, the vehicle suddenly shut down on the freeway and completely lost power. In both cases, I was fortunately able to steer the car to the shoulder of the road, but this posed a serious safety risk. During these incidents, multiple system error messages appeared on the dashboard, including alerts related to braking, lane departure, and other critical functions. Alarmingly, this same issue has also occurred while the vehicle was parked in my garage. Each time, the only way to temporarily resolve the issue has been to shut off the vehicle and restart it. Upon restarting, the only remaining warning is related to the braking system, along with a prompt to bring the car to the dealership. If the vehicle is restarted again, all error messages disappear. I have contacted my dealership after each occurrence and brought the vehicle in for inspection. My car is currently at the dealership, and I am awaiting information on the cause of the problem and the proposed resolution. After the first time it happened, I have taken video/pictures of the errors and supplied same to the dealership. I consider this a serious safety concern—not only for myself but also for any passengers and other drivers on the road. Quite honestly, I am now afraid to drive the car, knowing that it could unexpectedly shut down at any moment without warning.
NHTSA complaint #11670239 — an unverified report by a vehicle owner.
On 5/8/25 when the light turned green at the stop light, my car shut down while the gear was on drive. It immediately came back on with the dashboard showing warnings for the (TPMS), brakes system, stability system, among others. I accelerated while on drive but the car did not move forward. I turned the flashers on. I had cars behind me honking and going around me. I put the shifter in Park. A car behind almost rear ended me. I tried a second time to go by shifting the gear to Drive but I had no luck. I put it back in Park and turned it off. I turned it back on and the dashboard seemed fine, the car accelerated when I shifted it to Drive. This is the second time that the same car shut down on me, the first time was over a year ago when the car was in motion at around 40 mph, I was able to pull over. The first time the dealer replaced a part and told me the problem was fixed. This time around the advisor said there's nothing they can do because they can't replicate the problem. It's very concerning because it can happen at any time anywhere at any speed.
NHTSA complaint #11660177 — an unverified report by a vehicle owner.
I was driving on the freeway and my engine lost power and all the lights on my dashboard went haywire. I tried to get off the freeway but with the loss of power made it extremely difficult and dangerous. I thought I was going to get into an accident since my car slowed down so abruptly. I had to limp my way across traffic which was very scary. The car was jerking and shaking. I finally got to the side of the freeway and the car did not want to continue so I called for a tow truck and waited on the side of a busy highway. The tow truck brought my car to the Honda dealership which diagnosed the problem immediately as a blown head gasket. They said it was a known problem and the mechanic knew what to look for. They fixed the head gasket and I have my car back. My car only has 92k miles and I don’t think the head gasket should fail this early in the vehicles life. I properly maintain my engine with routine oil changes. There is no reason the engine should break down like this. I feel that there is a defect in Honda’s head gasket.
NHTSA complaint #11659652 — an unverified report by a vehicle owner.
I was driving approximately 60 mph on a local highway when my the check engine light came on. The dashboard then started flashing warning messages for multiple error messages stating that many features were failing such as power steering, acceleration, brakes, lane assist, stability assist, and more. My car then lost power and decelerated, coming to a complete stop in the middle of the highway. I was unable accelerate or steer my vehicle to the side of the road. No one hit me but this could have easily caused an accident where either myself or others were hurt. I turned the car off and when I restarted it, my dashboard message stated that I had a brake system problem and that I should see my dealer. I was able to drive to the dealer where they ran a diagnostic and could not replicate the problem. They only stated it was a loss of communication in the computer but that "it would probably not happen again." They did nothing to identify what could have caused the loss in communication and said if it happened again, to bring the car back. I plan to take it to a certified mechanic to inspect the vehicle but I feel very unsafe driving a car that may lose power.
NHTSA complaint #11645208 — an unverified report by a vehicle owner.
The vehicle unexpectedly stalled - lost power while driving and the brake system warning light came on. There were no warning lights, messages or other issues with the vehicle prior to this failure. Was fortunate that the car coasted to a stop on the side of a busy road with no traffic following behind. The vehicle was then towed to a Honda dealership for inspection. Was advised by the service department that there was a software update - unbeknown to us. The error code was cleared and the service department completed the pcm update per Service Bulletin 25-017.
NHTSA complaint #11643093 — an unverified report by a vehicle owner.
The CVT Power Train has a Vibration at 55 and Over. Also when Backing Up there is a loud high pitched sound. The Car has only 8600 hundred miles. There is no excuse for this issue with the car. Thanks for your time.
NHTSA complaint #11642448 — an unverified report by a vehicle owner.
Recurring issue where car loses all power to the powertrain, brakes, etc. while driving. Electrical systems inside the car and lights still functions, but complete loss of system to accelerate or keep the car going. After incident, computerized dashboard scrolls through multiple errors and then repeats (I have video). When I turn the car to the off position and then restart, only a single error for the braking system shows on the dash/computer system. If I turn it off again, and then back on, all errors are gone and the car drives "normally." Dealership could not repeat the issue and said computer system did not show any errors, even when I showed them pictures of the errors. First occurrence was 3/6/2024 on freeway during rush hour traffic, ~55mph. Car had 8010 miles on it. Second occurrence was 1/15/2025 on side highway where speed limit was 55mph; I was traveling about 40mph. Third occurrence on 2/7/2025 was just starting from a red light at an intersection and just made it through the intersection when car failed. Taking to dealership again for diagnosis.
NHTSA complaint #11641449 — an unverified report by a vehicle owner.
I was driving at about 40 mph and the car lost all power and stopped in the middle of the road. Most all of the warning lights were on like low air pressure, reduced brakes and a brake problem light etc. Turned the car off and restarted and drove another 5 miles with the brake problem light still on. Stopped and restarted car and the brake light went off and all seems normal now. From my reading on Honda Accord Forums it might be a bad ICM unit? Will be contacting a Honda dealer soon.
NHTSA complaint #11632339 — an unverified report by a vehicle owner.
Mid October 2023, we driving on the freeway and the car started to slow down on its own. We could not accelerate to match the speed of cars around us or to get the speed limits in a 55 to 65 zone, making it dangerous for us and others to continue driving on the freeway at extremely slow/low speeds. We towed it the dealership, who said it was defective spark plugs. This car was only 4 years old with extremely low millage and the spark plugs should've last a lot longer. They changed the spark plugs under warranty. Late November 2024, we were getting off the freeway and the check engine light came on but there were no service codes. Everything was running normally except for the engine was making a loud noise. We parked at a shopping center and approximately 30 minutes later, restarted the car and all these messages and icons appeared for: Vehicle stability assistant system problem, Hill start assistant problem, ACC, Collision Mitigation breaking system problem, Road departure mitigation system problem, Emissions system problem, TPMS, Brake system problem, Electric power steering system problem. Towed it dealership and after an hour of diagnostics testing, they said it’s the spark plugs again! Just a little over a year and 2 out of 4 spark plugs are bad again. This is not right. We hardly drive this car and it’s only a little over a year since the spark plugs were replaced and a little over 5 years since we got the car brand new. Spark plugs are supposed to last 10 years or 100,000 miles and we’re not close to either. This time they said it's not covered under warranty and is over $800.
NHTSA complaint #11628409 — an unverified report by a vehicle owner.
While driving approximately 30mph the car lost all accelleration/power and slowed to a stop while still in Drive. First, this put me in an extremely DANGEROUS position in the middle of an extremely busy highway with cars almost hitting me several times. Dashboard displayed numerous flashing error messages. Some that I recall were: Low Tire Pressure TPMS, ABS, BRAKE SYSTEM, Power, and HOLD. I put the car in park and Drive again and it still wouldn't move. After turning it off and back on, I continued to have "BRAKE SYSTEM Brake system problems. Brake performance may be reduced. See your dealer. i." displayed. The car did resume driving functions and allowed me to get out of middle of road. Once stopping again and recycling, the warning signals went out and I drove home.
NHTSA complaint #11627413 — an unverified report by a vehicle owner.
On three separate occasions (the most recent of which was on Saturday), my vehicle’s dashboard lit up with various alerts, including “Brake System problem”, “TPMS problems”, and “Vehicle stability assist system problems”. At the same time, the vehicle’s accelerator completely stopped working. The issue would only resolve itself (and the alerts would go away) after I pulled over and restarted the vehicle twice. This issue happened on Saturday (on a highway), in March 2024 (driving out of a parking lot), and in February 2024 (on the highway). This is a safety issue because not being able to use the accelerator on the highway could potentially have lead to a serious crash. The dealers have been unable to replicate the issue. I've brought in the vehicle to dealerships on three occasions and have been told that because the alert wasn't actively visible when I brought it in after the fact.
NHTSA complaint #11627335 — an unverified report by a vehicle owner.
All of a sudden, the accelerator pedal stopped working --- all I really know is that the car wouldn't accelerate, regardless of how much I pressed on the pedal, and the car had to roll to a stop. A bunch of warning lights came on about the brakes malfunctioning, but I don't remember if the brakes actually stopped working (I was more focused on the fact that I couldn't accelerate --- this happened right as I was starting to move after a red light turned green). Thankfully this happened when I was going slowly in a residential area --- if I had been on the freeway and unable to get over to the shoulder before the car came to a halt, this could have caused a serious/fatal accident (or if the brakes really had stopped working, even in a residential area I could have crashed into something/someone). The car remained unresponsive until I turned the whole thing off and on again, at which point it started working like normal (although still with the warnings). I took the car to my dealership and they ran diagnostics, but they couldn't find anything and couldn't reproduce the problem when they drove it around, so they just shrugged and said I should "keep an eye on it and see if it happens again". So unfortunately I don't know what caused the problem or what to inspect (but I'm certainly not going to keep driving the car and risk this happening again).
NHTSA complaint #11622003 — an unverified report by a vehicle owner.
I am writing to let you know that 10/2/2024 my 2024 Honda Accord Hybrid Sport had sudden loss of drive-line power while I was traveling on the highway at 75mph. I was able to safely coast/navigate to the shoulder and stop. Steering and braking systems were normal. The car would not drive or restart once stopped. A tow truck was called to tow my car to the nearest Honda dealer to be fixed. There were no warning lights or sounds prior to this incident. Dealer determined root cause of problem was PCM not communicating with charging system. The PCM was replaced under warranty and my car was ready for pickup 10/18/2024
NHTSA complaint #11620806 — an unverified report by a vehicle owner.
Brand new car. After approximately six months, the drive shaft started making very loud popping noises when turning the steering wheel at low speeds. This happens 100% of the time with even minimal steering wheel movement. Honda is not sure if the drive shaft is rubbing against the frame of failing within the driveshaft. Honda is not reporting any service guidance so each dealership is pulling apart the cars looking for solutions. This should be recalled.
NHTSA complaint #11617977 — an unverified report by a vehicle owner.
I was pulling out of a parking lot when suddenly the car reported a problem with the braking system along with a number of other warnings. I lost all acceleration as I entered an intersection. I power cycled the car a couple of times before it returned to normal, and I was able to continue driving.
NHTSA complaint #11616098 — an unverified report by a vehicle owner.
On 1/21/2024, the car’s accelerator stopped responding and the car slowed to a stop. This happened twice previously on 6/25/2023, and again on 11/16/2023. Each time, the Honda dealer found “loss of communication codes,” and I was told via text on 1/25/2024 that “your Accord is communicating codes that we don’t have a repair for yet.” I filed a claim with American Honda on 1/31/2024 (case #13919840), and was told over the phone that nothing could be done to resolve the issue. Bernardi Honda gave me the vehicle back without any repairs. I still have the vehicle but I don’t drive it out of concern for my family’s safety.
