2018 Honda Accord: headlights failing or too dim

Filed Jul 21, 2026 · Brakes, Electrical · GA

What component or system failed or malfunctioned, and is it available for inspection upon request? I own a 2018 Honda Accord with approximately 132,000 miles. Shortly after my vehicle was serviced for the fuel pump recall, multiple warning lights and system failure messages appeared simultaneously. The affected systems include Road Departure Mitigation, Emission System, Adaptive Cruise Control, Auto High Beam, Collision Mitigation Braking System, Electric Power Steering, Vehicle Stability Assist, Tire Pressure Monitoring System, Hill Start Assist, and the Air Bag System. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? The failure of multiple safety and driver-assistance systems has created a significant safety risk. My vehicle is currently operating in limp mode, resulting in reduced performance and making it difficult to drive safely in traffic. The loss or malfunction of systems such as collision mitigation braking, power steering, vehicle stability assist, adaptive cruise control, and air bag monitoring increases the risk of an accident and could jeopardize the safety of both vehicle occupants and other motorists. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. I took the vehicle to a Honda dealership for diagnostic testing after the warning lights appeared. The dealer confirmed that multiple systems were reporting faults. I was advised that numerous components would need to be replaced at a substantial cost. Prior to the fuel pump recall service, I had not experienced any of these issues and the vehicle operated normally. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected by a Honda dealership for diagnostic purposes. To my knowledge, it has not been inspected by Honda corporate, law enforcement, or insurance representatives. Were there any warning lamps, mes

The contact owns a 2018 Honda Accord. The contact stated while driving 35 MPH at night, the driver's side headlight became inoperable. The vehicle was taken to the dealer, where it was diagnosed that the presence of condensation in the headlights had caused the headlights to experience a short circuit. The dealer replaced the entire driver's side headlight assembly. The vehicle was repaired at the contact's expense. The manufacturer was notified of the failure and a case was opened. The manufacturer later informed the contact that the repair could not be covered because the vehicle was used. Additionally, the contact stated that the third-party warranty did not cover the headlights. The failure mileage was approximately 34,000.

The issue has been observed repeatedly and confirmed by my service center during each replacement. It has occurred in different environments and driving conditions, and despite repairs, the problem persists. Honda refuses to replace headlamps after multiple faliures The vehicle has been inspected multiple times by my service center, but the manufacturer has not directly inspected it. No police or insurance representatives have been involved in the inspections. Each time the repair is made “All looks normal” The problem is preceded by a warning light on the dashboard indicating a headlight malfunction. Shortly after, the headlight fails, and then the turn signal malfunctions. The first instance of this problem occurred around 28,000 milesand it has recurred multiple times since then.

Water/ mist leaking into head lights and tail lights after a car wash. Front driver side headlight was not working and had to replace. Until replacing the part it might impact other turn signaling. FYI: have to replace whole unit as its LED and cannot just change bulb/ LED strip. There was a crash happened to the driver side more than an year and was into car wash's (or) car was in the rain with no impacts more than an year,. Replacing with Honda dealer costs around $700 for a headlight on each side.

The left front headlight assembly failed this includes the low beam headlight and turn signal and parking lights. Subsequently the turn signal and emergency flasher for the entire car failed. After having the assembly replaced the mechanic found that the turn signal flasher problem wass related to a blown fuse. The headlight assembly failure was diagnosed as being caused by water in the light assembly. In addition it was noted that the right front assembly was contaminated by water and will probably fail in the future.

After a service visit on May 27, 2023, at my local Honda dealership, I noticed condensation buildup in the front driver’s LED headlight. The car has never been in an accident, and there was no evidence of a strike from road debris. I initially suspected this moisture could be related to humidity, but it never evaporated and remained a problem. I troubleshooted other possible causes but eventually brought it back to the dealer for a more thorough investigation. The dealership determined that the headlamp was cracked/defective and worked with Honda to replace it. Just before the repair, the driver safety system generated multiple warnings about the lighting system and the turn signals failed to work. Once at the dealer, a blown fuse was discovered. It was presumably blown by the defective headlight and replaced. On October 30, 2023, I discovered new cracks in the front passenger LED headlight. Some condensation was also present. As before, the car has not been in an accident and there is no evidence of a strike from road debris. The pattern is strikingly similar to what transpired with the driver’s front headlight. In conclusion, I believe my headlight problems are caused by a manufacturing defect on some 2018 Honda Accord models. My experience with driver system alarms and inoperable turn signals due to a subsequently blown fuse demonstrate that defective headlights can create a serious safety hazard. I respectfully request your assistance with this situation and welcome the opportunity to find an agreeable solution.

The low beam lights abruptly stopped working without warning. The high beams, fog lights and interior lights work fine but I had to use my bright lights to get home which visually impaired oncoming traffic & myself because they flashed me with their bright lights. I called the dealership, and they said what happened was highly unusual and that led lights don't go out. Following this my system lights started to come on for the tire pressure and the brakes. They are still on and my tires work fine and brakes are working fine.

My car was purchased new in December 2018. It now has 119,231 miles on it. My problem is that my headlight warning lamps go on the minute I start my car, because moisture has somehow gotten into both headlight assemblies, which causes my headlights to stop working intermittently. I took my car to Keeler Honda in Latham New York to get it fixed, and they gave me a quote to replace two headlights in the amount of $3174.23. My car has never been hit nor has it ever been in an accident. And now I need to replace two headlights and I can’t believe how much money it’s going to cost me. I believe I have defective headlights, and although my car may be out of warranty, I think this is a design issue, and the cost to replace two headlights is unreasonable. I have attached pictures of the right and left front headlights, a picture of my dashboard warning light that comes on when I start my car, and a copy of the estimate I received from Keeler Honda in Latham New York for $3174.23. Just for the headlights alone, the cost is 2624.04. Who has that kind of money to replace 2 headlights? I wonder if I’m the only one with this issue. This is a serious SAFETY HAZARD when I’m on the road and my headlights turn off at night. What can I do? Thank you, Mark Febbie

Evening before problem started it was a heavy rain in nyc. Morning I started the car and was immediately received 4 messages: "lkas: lane keeping assist system problem. See your dealer.". "road departure mitigation system problem. See your dealer.", "blind spot information system problem. See your dealer.", "auto high beam problem. Manual controls available. See your dealer.". Turn signals did not work. Hazard lights did not work. Trunk release did not work. Backup camera did not work. Moved to dealer (25 minutes away). But did not start the service. After turning off and start the car again all displayed failures were gone. Waiting for the next heavy rain.
