ENGINE, FUEL/PROPULSION SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I purchased my 2018 Honda Accord Sport from CarMax on January 16, 2026, and I have had several serious problems with the vehicle since purchasing it. Every warning light on the dashboard has come on, my radar system will not stay calibrated, and I have been told that my fuel injectors need to be replaced. In addition, the relay module was already broken when I received the vehicle, which causes the interior lights in my car not to work properly. These issues have caused serious concerns about my safety and the safety of others because I cannot depend on the vehicle’s safety systems or know when another component may fail. The vehicle and affected components are available for inspection upon request. I have attempted to get these problems addressed, but I have not been able to get a satisfactory resolution. The issues have been identified/diagnosed, and I am seeking further inspection to determine the full extent of the problems. I have not had the vehicle inspected by the police or an insurance representative, but I am trying to get the manufacturer/dealer involved so these issues can be properly documented and addressed. I am especially concerned because I have only had this vehicle since January 16, 2026, and I have already put a significant amount of money into it while still owing a substantial amount on the loan. I was also informed that the vehicle could potentially be considered a total loss within the next couple of months. I do not believe it is reasonable for me to be left responsible for a vehicle that I recently purchased from CarMax and that has developed or revealed so many serious problems. I am requesting assistance in determining whether these issues can be properly repaired, whether the vehicle is safe and reliable to drive, and what options are available to me for a resolution given the amount of money I have already invested and the remaining balance on my vehicle loan.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
In September 2025, all dashboard lights came on while driving down the road. I immediately pulled over and turned the car off. When turning the car back on, all lights remained on and I drove to the nearest repair shop, where at this time it was beginning to run hot. I was told at this point that the head gasket had blown and this would need to be replaced. I replaced the head gasket for $4100.00. After that, in October 2025, I had to replace the fuel injectors and coil packs. In February 2026, driving down the road, the car was not running hot but all lights came on the dash again and it went into limp mode. The car had to be towed to a repair shop where it was stated that coil packs needed to be changed again. In August 2026, the turbo had to be replaced, resulting in an additional $2500.00

ENGINE AND ENGINE COOLING
The contact owns a 2018 Honda Accord. The contact stated that while driving at an undisclosed speed, several unknown warning lights were illuminated, and the vehicle went into LIMP Mode, and the vehicle failed to exceed 5 MPH with the accelerator pedal depressed. The vehicle was taken to a dealer where it was diagnosed and determined that the turbo boost and head gasket needed to be replaced. The vehicle was repaired; however, the failure persisted. The failure had occurred on several occasions. The vehicle was towed to an independent mechanic where it was diagnosed and determined that the engine needed to be replaced. The manufacturer was notified of the failure. The failure mileage was approximately 100,000.

ENGINE
I am reporting a suspected head gasket/engine defect involving my 2018 Honda Accord Sport. My vehicle experienced multiple engine-related problems before ultimately requiring head gasket replacement and cylinder head repair. On July 27, 2024, at approximately 161,480 miles, the turbocharger was replaced. In September 2025, at 207,539 miles, my vehicle was serviced at Joe Morgan Honda, an authorized Honda dealership. During that visit, the Honda technician documented that the cooling system fluid level was low and that no external leaks were found. The technician documented that they suspected the head gasket was causing internal coolant loss over time. I was instructed to monitor the vehicle and was provided an estimate of approximately $4,400 plus tax for head gasket replacement. I specifically asked the Honda service advisor whether the head gasket could be repaired at that time or whether anything could be done to prevent the suspected problem from progressing. I was told there was nothing that could be done at that point other than monitor the vehicle. Within weeks, multiple warning lights illuminated on my dashboard and the vehicle began experiencing significant drivability problems, including hesitation, misfiring, and loss of acceleration. The loss of acceleration was particularly concerning because the vehicle did not respond or accelerate normally while being driven. I took the vehicle to Integrity Automotive on September 25, 2025, at 208,583 miles. The engine was checked, and the ignition coils and spark plugs were replaced. Despite those repairs, the vehicle ultimately required major engine repairs on November 8, 2025, at 210,230 miles. The cylinder head gasket was replaced and the cylinder head was serviced/repaired. The fuel injectors, spark plugs, and serpentine belt were also replaced, and the cooling system and drivability/performance were checked. Only approximately 2,691 miles elapsed between the Honda dealership documenting the suspected i

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, ENGINE
Issue 1: Faulty Collision Mitigation Braking System & Subsequent Crash Incident Details: In July of 2025, my vehicle’s automatic braking warning lights randomly activated and triggered an unprompted, emergency stop on [XXX]—despite having no vehicles ahead of me. This sudden malfunction directly caused a rear-end collision on the interstate. Documentation: A formal crash report was filed with the Georgia State Patrol. Ongoing Risk: The false automatic braking warnings continue to trigger randomly, creating an extreme safety hazard for myself and surrounding traffic. Issue 2: Premature Turbocharger Failure & Cracked Head Gasket Diagnostic Timeline: Immediately upon picking up the car from a body shop repair, every warning light on the dashboard illuminated erratically. After Ed Voyles Honda in Marietta claimed nothing was wrong, the body shop replaced a potentially loose battery cable. The issue persisted, and Shottenkirk Honda in Cartersville ultimately diagnosed a total turbocharger failure in March 2026. Out-of-Pocket Cost: Honda denied any goodwill coverage despite the widespread, documented failure of these 1.5L engines across 2018–2023 models. I paid $1,700 out of pocket to replace the turbocharger. Escalating Failures: Shortly after the turbo replacement, the head gasket cover cracked—another notorious, widely recognized defect inherent to this specific engine setup. At only seven years old, this vehicle has proven to be unreliable, dangerous, and financially burdensome. The known defects in the 1.5L powertrain warrant a widespread recall. Given my long-standing loyalty and the severe nature of these defects, I request a full reimbursement of the $1,700 turbocharger repair costs and an immediate investigation into the phantom braking issue. I expect a prompt reply outlining how Honda intends to resolve these safety issues. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Turbo has gone out and it's several thousand dollars to get fixed and will eventually affect the overall lifespan and performance of the engine if not repaired in a timely enough fashion. There is no recall for this specific issues even though thousands of Honda Accord owners are dealing with the same failure/repair and there are no offers of goodwill assistance from the dealership or manufacturer. The dealership assured that engine failure is inevitable without a turbo replacement and they can't determine the extent of the damage that's already been done to the engine since the turbo showed signs of failure.

i have a 2018 honda accord. it used to have only wired carplay. i paid a honda dealer for the official advertised wireless carplay upgrade. over a year later suddenly the head unit doesn't work. it just shows "please insert usb drive containing valid software license file, and press ok button." many people online are reporting this issue. the honda dealer that did my original install refuses to fix this issue free of charge, and they are unable to assure me that they are aware of the issue and have a confirmed fix. i refuse to pay them to do a diagnostic just for them to tell me they can't fix it, or to give me a temporary fix that will break again later

UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
While driving my 2018 Honda Accord Sport 1.5T, multiple warning lights suddenly illuminated on the dashboard at the same time and several warning messages appeared. The vehicle displayed warnings for different systems, including a message stating, “Hill Start Assist Problem. Vehicle May Roll Upon Brake Release. See Your Dealer,” along with the check-engine light and several other warning indicators. I purchased this vehicle brand new in 2018, and since the day I purchased it, I have consistently had the vehicle serviced and maintained at an authorized Honda dealership. I have relied on Honda to perform the recommended maintenance and address any problems with the vehicle. When all of these warning lights and messages appeared, I took the vehicle to the Honda dealership. The dealership adjusted the valves and told me that everything was fine. Approximately one week later, I had to take the vehicle back because the problem was not resolved. At that time, I was told that the vehicle needed a head gasket. The vehicle had also previously required a turbo replacement. Because of the seriousness of the head-gasket diagnosis, I obtained a second opinion from another repair facility, and they also determined that the head gasket was the problem. I do not understand how a vehicle that I purchased new and have consistently maintained through Honda could experience these significant engine-related problems. I am especially concerned that numerous unrelated warning lights and safety-system messages appeared simultaneously before the head-gasket problem was diagnosed. I am submitting this complaint because I believe this issue should be investigated to determine whether other 2018 Honda Accord 1.5T vehicles are experiencing similar head-gasket, turbo, and multiple-warning-system problems and whether these failures may represent a defect that should be addressed by Honda or through a recall.

UNKNOWN OR OTHER
What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle's head gasket has been identified as needing replacement. The Honda dealership inspected the vehicle on Wednesday, August 12, 2026, and confirmed that a new head gasket is needed. The vehicle and the failed component should be available for inspection upon request. How was your safety or the safety of others put at risk? The ongoing malfunction caused numerous warning lights and messages to appear on the dashboard over approximately the past two months. Because the vehicle was displaying multiple warnings and experiencing an apparent engine-related issue, I was concerned about the vehicle's reliability and safety while driving. An engine malfunction could potentially cause the vehicle to lose power or become inoperable unexpectedly, which could put me and others on the road at risk. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The problem was inspected and confirmed by a Honda dealership on August 12, 2026. I was informed that the vehicle needs a new head gasket. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? Yes. The vehicle was inspected by an authorized Honda dealership. To my knowledge, it has not been inspected by police or insurance representatives. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes. For approximately two months prior to taking the vehicle to the dealership, multiple warning lights and messages began appearing on the dashboard. The warnings continued to appear and became increasingly concerning, which ultimately led me to take the vehicle to the Honda dealership on August 12, 2026, where I was informed that the head gasket needs to be replaced.

The car suddenly stopped speeding up on the highway, and the check engine light began to flash. There were no warning signs before this occurred. I was driving with my kids when I had to think and move quickly off the highway because there were other cars behind us. The car would only roll because it wouldn’t speed up. Yesterday, on August 17, the car was towed to a Honda dealership, where they ran some tests. They found out that the car has a blown head gasket.
