2023 Honda Civic Electrical System Problems

I am reporting repeated electronic safety system malfunctions in my 2023 Honda Civic Sport sedan that occurred while driving at highway speeds and present a serious safety concern. In June 2025, while driving at highway speed, multiple warning lights and messages suddenly appeared, including: Brake System Warning, Road Departure Mitigation System Warning, Parking Brake/Brake Hold Warning, and Adaptive Cruise Control Warning. These warnings appeared simultaneously without prior notice, raising concern about whether the braking and safety systems were functioning properly while the vehicle was in motion. I took the vehicle to a Honda dealership for diagnosis. The dealer did not identify a specific electronic or mechanical defect and instead claimed the issue was caused by liquid spilled near the electronic parking brake switch. I was told the repair was not covered under warranty and paid approximately $600 out of pocket. No evidence was provided explaining how this would cause failures across multiple safety systems. In January 2026, the same group of warning lights appeared again under similar conditions while driving at highway speed. This recurrence strongly suggests the issue was not caused by driver error but may be related to an intermittent electronic, sensor, or control system defect. I have a scheduled dealer appointment tomorrow to address this second occurrence of electronic malfunctioning. Because these warnings involve critical braking and collision mitigation systems and occurred while the vehicle was in motion, they present a potential safety risk. I am submitting this complaint so NHTSA can document and evaluate whether this represents a broader safety defect.

On over a dozen occasions my vehicle’s check engine light randomly comes on and then my car stalls out while driving and begins decelerating quickly. It is very dangerous and scary when this has happened on the freeway or in places where there is nowhere to pull off the road. My Honda Civic is less than 2 years old and has already been in the service department at Honda for a combined total of more than 30 days. Honda keeps trying to replace things but the issue keeps happening and they haven’t been able to properly diagnose or fix the problem. It is unsafe to drive this car and Honda has been unable to fix it. I bought this car brand new with 0 miles and the issues started early on before I reached 20,000 miles. I attached one of the most recent invoices from Honda where they noted the fuel injectors failing and codes of misfires in all cylinders. They most recently tried replacing the fuel injector but it still hasn’t fixed the problem. This car is unsafe to drive and has been in the shop multiple times for more than 30 days for the same issue that they can’t seem to fix.

When I first got the car. I had the cigarette lighter go out and the car had about 29,000 miles on it. The put two fuses and they blown. Now my car ac has went out. I have been told by a professional that the car sounds like it has a lot an electric issue. I have a friend who has the same issue with the same car with her CarPlay and cigerette lighter not working properly

Dear Honda Customer Support Team, I want to address an urgent safety concern with my 2023 Honda Civic, which has been affected by the recent recall (NHTSA Recall Number: 24V-744, MFR Campaign ID: SJS) issued on October 3, 2024, for 2022-2025 This recall addresses a defect in the steering gearbox worm wheel, which can swell during use, resulting in a reduced grease film thickness between the worm wheel and worm gear. Additionally, the worm gear spring preload was set too high, increasing friction and causing the steering to become resistant. This defect can create dangerous driving conditions, significantly raising the risk of a crash or injury. On multiple occasions, I have experienced instances where the steering has become unresponsive, effectively “locking up” while driving. These occurrences have been extremely distressing, impacting my confidence in the vehicle's safety and contributing to substantial mental distress. Additionally, I have noticed recurring issues with the Electronic Power Steering (EPS) system, such as electrical malfunctions that cause the car to stall unexpectedly, activate the automatic stop feature, and produce erratic sensor behavior. I have reported these concerns to my dedicated dealership, but unfortunately, the issues remain unresolved. On November 2, 2024, I brought my vehicle to White Plains Honda at 61 Bank Street, White Plains, New York 10606, after scheduling my appointment two weeks in advance. However, I was informed that the replacement part required to resolve the steering gearbox defect is on backorder with no confirmed availability date. Considering the safety risks associated with driving my vehicle in its current state, I am deeply concerned about the indefinite delay in repairs. Given the critical nature of these safety concerns, I am formally requesting an immediate replacement vehicle to ensure my safety and that of my passengers.

Hatch leaks and center console plugs are incorrect and cause a fire hazard

Rodents have chewed through the wiring on my vehicle twice within 7 days. Dealer fix of "rodent-deterrent" tape did not work. All systems are compromised by this occurrence -- emissions, braking, acceleration, lane-keep asist, etc. Using soy-based wiring on vital components is not safe for the consumer.

About 30 minutes into a drive the steering wheel or electronic steering will begin to malfunction. When driving at high speeds, you are unable to make small minor corrections to stay center in your lane due to the steering wheel feeling like it’s sticking in one direction. It takes a considerable amount of force in order to make the correction resulting in an over correction. When traveling at high speed this can put the driver and passangers at risk because an over correction can cause the car to lose traction with the road. I’ve taken the car into Honda and it is currently being inspected. They told me yesterday that they were ‘having trouble replicating the problem’ which doesn’t mean the problem isn’t there. As far as I know and seen there have no being any light indicators on.

When I was driving my new 2023 Honda Civic Touring’s the engine started running rough and the check light indicators came on with the following items to “See your dealer” despite this car being less than 3 months old and with just over 1,000 miles on the odometer: - Brake System Problem… - Electric Power Steering System Problem… - Electric Parking Brake System Problem… - Tire Pressure Monitor System Problem… - Emission System Problem… Some of these above items negatively affect the safe operation of the vehicle and increase risk to the occupant(s). After coordinating with the Honda dealership where we purchased this Civic and the Honda Roadside Assistance, they towed our disabled Civic to the closest Honda dealership. A Honda Service Advisor informed us our Civic had a major engine issue (cracked engine block) which was a manufacturer's defect. After 36 days they completed the major warranty repairs totaling over $6,000 (primarily replaced the engine short block which eliminated the above listed issues). It should be noted, the two local Honda dealerships and Honda Roadside Assistance (1-800-864-5211) were very professional and helpful. However, to our surprise the American Honda Motor Co, Inc; Honda Automotive Customer Service, [XXX] ) has been unresponsive.

The steering wheel is very very hard to turn some times when making minors adjustments on the highway to keep in the centre of the lane; only happen on high speed, sometimes 50km/h-80km/h the issue occurs too. However, after a while, it’s even more noticeable and it happens more frequently and at low speed too. Right now, it happens very frequently around 50km/h-130km/h. I am very concerned regarding this, and I been to the dealership two times but they could not find out the issue. The third time I went to the dealership they finally figured it out and ordered parts in for me; nevertheless, it’s been one/two months but it’s still not here yet. But the issue is getting worse.

The contact owns a 2023 Honda Civic. The contact stated while driving at various speeds, several error messages became displayed on the instrument panel, including the brake mitigation system, low speed braking, and cruise control. The vehicle had been taken to the dealer on several occasions however, the dealer failed to determine the cause of the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was unknown.

Driver information interface (a-type) functions erratically and in a highly distracting manner. Vehicle has very low mileage-275.

The week of February 26, 2023 I was sitting at the traffic light and when I went to press the gas the car wouldn't move and it shut off. So it appears that the auto start stop did not re-engage. I had to put on my blinkers so that traffic could go around me. I pressed some buttons and it finally started up after a minute or so. Pretty alarming considering that I only had the car for 2 months and it's a brand new 2023. Also, on 3/6 I went to start my car and it wouldn't start. It asked me to place my key fob on the start stop button. Then the car started. I took it to the dealer and they can't find anything wrong and that's even more scarier. Also, the car seems to gas up when it's in park and I have my foot on the brake but no one can explain what's going on with my brand new car.
