Formal Complaint Regarding Repeated Warning Lights and $2,600 Turbocharger Repair Recommendation – 2018 Honda Accord Dear Honda Customer Service / Dealership Management, I am writing to formally express my concern and frustration regarding ongoing issues with my 2018 Honda Accord and the diagnosis and repair recommendation I have received from the dealership. My vehicle has been experiencing an intermittent problem where multiple warning lights and/or error indicators on the dashboard come on at the same time. The problem does not remain consistently active. The warning lights may stay on for several days, then disappear, and later return again. This has happened multiple times. Because the issue is intermittent, I have attempted to have the vehicle properly diagnosed rather than simply replacing parts based on a temporary warning or error code. I have also had a diagnostic scanner connected to the vehicle. At various times, the scanner has not shown an active problem or has not provided a clear explanation that would justify replacing a major and expensive component. Despite the intermittent nature of the problem, I have now been advised that I may need to spend approximately $2,600 to replace the turbocharger due to an underboost condition. I have serious concerns about this recommendation. First, I want to understand exactly how the dealership determined that the turbocharger itself has failed and that replacing the turbocharger will actually resolve the underlying problem. An “underboost” condition or related diagnostic code does not necessarily, by itself, establish that the turbocharger is defective. There can potentially be other causes of an underboost condition, including issues involving boost-control components, hoses, connections, sensors, vacuum or pressure leaks, wiring, electronic controls, or other related components.

In the duration of ownership with this vehicle, there is always lights lighting up on the dashboard which trigger my sensors and causes my dashboard to light up like a Christmas tree. I do not feel safe when that happens randomly in the middle of driving on the highway.

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 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.
