2018 HONDA ACCORD Complaints

Major head gasket failure with no warning while pulling out onto a busy road. There is a major design flaw with the head gasket, no recalls or preventative notices from Honda whatsoever! My wife was put into a dangerous situation once the car went to limp mode with no warning while getting onto a busy road. Multiple lights on the dash lit up when the car entered limp mode. The car was immediately towed to a Honda dealership and was diagnosed with a blown head gasket. Service manager stated this is a VERY common occurrence and is indeed a design flaw. Car was fixed with no help from Honda for their faulty design $5100...

The AC system on my 2018 Honda Accord 2.0T stopped blowing cold air due to refrigerant leaks in both the AC condenser and AC evaporator. The condenser is covered under Honda's warranty extension (Service Bulletin 21-018) which acknowledges a manufacturing defect where R-1234yf refrigerant corrodes the condenser tube walls. The dealer confirmed the evaporator is also leaking from the same corrosion defect. The dealer states both must be repaired together because the system cannot hold refrigerant with a leaking evaporator. Honda corporate is refusing to cover the evaporator repair despite it being caused by the same known manufacturing defect. This is a systemic issue affecting 2018-2020 Accords and other Honda models using the same AC components and R-1234yf refrigerant.

While driving at highway speed, the engine suddenly stalled without warning, resulting in a complete loss of power. This created a dangerous situation as I was unable to maintain speed or safely maneuver with surrounding traffic. At the time of the incident, all electrical warning lights illuminated on the dashboard simultaneously. Prior to this event, there were no clear warnings indicating imminent failure. The vehicle was later diagnosed with a failed head gasket and turbocharger issues. The sudden engine stall while in motion presents a serious safety risk, particularly at highway speeds, as it increases the likelihood of a crash due to loss of propulsion and reduced driver control. This issue appears to have occurred unexpectedly and without adequate warning

Head gasket had to be changed out. I have seen multiple cars having the same issue with this model. The vehicle sputtered and would not let me drive above 40mph. It was a safety issue when I first had it and it occurred in the freeway.

Car was jerking when acceleration. Dealer inspected the vehicle and said the head gasket is blown. It overheated a day after Honda dealership fixed my water pump.

Transmission started bucking at 50k miles, the problem has gotten substantially worse at 60k miles. Rough downshifting and upshifting in low gears. Will slam into gears 2-3 often and cause driver and passengers to lurch forward. Will cause very rough acceleration at times and causes a danger in traffic given the speed becomes unpredictable. Transmission does not know what gear to be in even after ATF type 2.0 fluid change following dealer procedure. This is putting me and other drivers at risk because I cannot control my speed when transmission is slamming in between gears. No warning lamps, undetected by cars TCU.

Head gasket failed at 58k miles without overheating per assessment at honda dealership. Safety was affected by going into limp mode instantly turning left onto 55 mph 4 lane road, no warning lights prior going into limp mode. Brief misfire occurred prior to incident, (did not know at time because it did not seem significant and no warning light). Dealer reports multiple 2018 honda accord 1.5L head gasket and fuel injector failures. Unknown if manufacture would inspect. In addition fuel injector has completely failed and requires replacement per honda dealership assessment, this occurred after dealership repaired head gasket. Waiting for final repair invoice, can and will provide upon request
