2018 HONDA ACCORD Complaints

My vehicle started stalling and shaking right before all of the warning lights on my dashboard came on and the safety features stopped working (brake assist, brake hold etc). After checking, the spark plugs were all burnt out so I changed it along with the coil pack and this remedied the issue temporarily until it happened again a few weeks later. This time, I was on the highway going at around 55mph when the car suddenly started stalling and the speed dropped to 10mph. Luckily, I was in the right lane and had no cars behind me because it would've caused an accident. I pulled over to the side of the highway, shut the car off for 15 minutes and then took the nearest exit with my hazard lights on, going at around 10 mph. I took my car to the dealership and they stated that I need a new head gasket which will cost me from $5,000 to $9,000. After doing research, there are hundreds of other Honda's which are experiencing this same issue. Currently, the condition is worsening as the car is shaking abruptly and I am not able to drive over 30mph. I also experienced a burning smell.

Starting in the middle of July my 2018 Accord began showing a "Supplemental Restraint System Problem. See Your Dealer." message. Upon dealer(Ed Martin Honda) inspection it was found that the passenger seat airbag sensor was faulty and needed replaced. Upon checking I found that there is a recall for the faulty sensor but my VIN is not included. I urge further inspection as this appears to be a more wide spread issue than Honda is reporting.

The contact owns a 2018 Honda Accord. The contact stated that while driving approximately 40 MPH, the air bag warning light illuminated, and the message "SRS Fault - See Dealer" was displayed. The vehicle was taken to a dealer where it was diagnosed and determined that rodent had eaten through the wiring and that the wiring insulation was soy-based, and the air bag cable and the harness cable needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 68,000.

I own a 208 Honda Accord Sport 1.5L Turbo that I purchased new. At approximately 69,000 miles, the vehicle experienced a cylinder head gasket failure, allowing coolant to enter the engine. The vehicle was diagnosed by Honda dealership, which recommended replacing the cylinder head gasket, cylinder head bolts and spark plug at an estimated cost $6,500. Prior to this failure, the vehicle began overheating and warning indicators appeared. The failure resulted in the vehicle becoming unsafe to operate because continued driving could have caused severe engine damage or an unexpected loss of power. The vehicle has been maintained throughout my ownership and I have retained maintenance records. I was also informed by Honda dealership that they have seen multiple 2018 Honda accords 1.5L turbo vehicles come in with the same head gasket issue. Based in my experience, I believe this may represent a recurring defect affecting this model.

Since 11/2026 I have had issues with this car. 11/2025 mis-fire on cylinder 2 replaced turbo and spark plugs due to all dash lights on and would not accelerate over 10mph. 6/2026 all dash lights lit up again and would not accelerate over 1-20 mph misfire on cylinders 1 and 3 codes P0301 and 0303. Replaced coils, spark plugs and found fuel leaking out of injectors. Replaced injectors. 07/2026 all dash lights lit up again and would not accelerate over 10-20 mph. Found leak in the cylinder head gasket, replaced head gasket which had to go to a machine shop to machine the head.

At roughly 83,000 miles, my 2018 Honda Accord 1.5Lt experienced a major engine failure caused by a blown head gasket. At the time of the failure, I was driving on a major road. While accelerating, the vehicle had "bucked" forward, which triggered the engine light to flash at which time the vehicle had no longer responded to me pushing on the gas pedal. This caused a major safety issue as I then had to get off of the road to avoid collisions with other vehicles. I immediately brought the car to a Honda dealership, who confirmed that the head gasket needed to be replaced. There were no prior indications that the vehicle had any issues.

The contact owns a 2018 Honda Accord. The contact stated that while driving approximately 70 MPH, the engine temperature rose, and the vehicle lost automotive power. The contact pulled over to the side of the road, turned off the vehicle, and allowed the engine to cool down before restarting the vehicle, and the vehicle returned to normal operation. No warning lights were illuminated. The failure had occurred on several occasions. The vehicle was taken to the dealer to be diagnosed; however, the cause of the failure was undetermined. The vehicle was not repaired. The vehicle was taken to another dealer, Balise Honda of West Warwick (509 Quaker Ln, West Warwick, RI 02893); where it was diagnosed with a blown head gasket, which was caused by coolant leaking into the cylinders. The contact was informed that the head gasket, fuel injectors, and several other unknown parts needed to be replaced. The contact researched and was made aware of an unknown NHTSA Campaign; however, the VIN was not included. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 166,000.

The contact owns a 2018 Honda Accord. The contact stated that upon starting the vehicle, the engine and TPMS warning lights illuminated. The message that the vehicle should not be driven was displayed. The lane assist feature was inoperable. The contact disconnected the battery, and the warning light disappeared. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 55,000.

At approximately 44,000 miles, multiple warning lights illuminated on the dashboard of my 2018 Honda Accord (1.5L turbocharged engine), including brake system, electric power steering, and driver-assistance/collision-mitigation warnings, accompanied by a rough start and an engine misfire. I took the vehicle to an authorized Honda dealer, which performed a diagnostic scan and a borescope inspection. The dealer confirmed engine coolant leaking internally into cylinder 3, a confirmed cylinder 3 misfire (code P0303), and a low coolant reservoir, and advised that the vehicle was not safe to drive. The diagnostic scan also returned fault codes across multiple safety systems, including ABS/VSA stability control, electric power steering, the electric brake booster (low-voltage power circuit fault), and the driver-assistance/collision-mitigation system. This is a head gasket failure allowing coolant to enter the cylinders — a failure mode widely reported on this engine — and it occurred at low mileage, creating a risk of engine misfire, stalling, and loss of power. No crash, fire, or injury has occurred. The dealer's repair order documenting these findings is available on request. I have reported this to the Honda corporate, and they are not responding and stalling the delivery or any update on the case. It has been 3 weeks, and it is causing prolonged inconvience and safety issue to me and my family
