Owner reports
Selected complaints filed with NHTSA by 2018 Honda Accord owners, lightly cleaned up (personal details are redacted by NHTSA).
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 contact owns a 2018 Honda Accord. The contact stated that after the vehicle was repaired under an unknown recall repair, the contact stated that while attempting to depress the brake pedal, several unknown warning lights illuminated. The contact stated that whenever the warning lights were illuminated and the brake pedal was depressed, the rear brake lights failed to illuminate as designed. The contact stated that while the lights were turned off and the brake pedal was depressed, the headlights erroneously illuminated. The vehicle was not taken to be diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 46,000.
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. …
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. …
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.
I owned a 2018 Honda Accord,i got it new from the dealership so im the only owner of this vehicle. my headlights keep building condensations prematurely causing them to fail . I have already replaced multple headlights because of this . also when the bulbs go out honda made it where the bulbs can not be replaced at all. these headlights cost close to $1000 each plus 500 in labor to installed. theres should be a recall for this as its costing me soo much money . I hoping we must hold accountability to its highest level so consumer dont have suffer like this. Thank you so much for reading!
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.
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.
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.
