ELECTRICAL SYSTEM
The contact owns a 2018 Honda Accord. The contact stated that after stopping the vehicle, the check engine, stabili-trak, steering, and the Forward Collision Avoidance warning lights were illuminated, with unknown messages displayed. The vehicle was taken to the local dealer, and a system reset was performed, and the contact was informed that the battery needed to be replaced. The contact stated that the battery was recently replaced. The contact retrieved the vehicle, and hours later the failure reoccurred. The cause of the failure was not yet determined, and the vehicle was not yet repaired. The manufacturer was not yet contacted. The failure mileage was 127,000.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: WARNING
While driving, the vehicle suddenly jerks or “jumps,” followed immediately by a noticeable loss of power. Shortly after this occurs, the multi-information display shows a series of warnings that include: Collision Mitigation Braking System Problem – See Your Dealer Adaptive Cruise Control System Problem – See Your Dealer Road Departure Mitigation System Problem – See Your Dealer Auto High-Beam Problem – Manual Controls Available – See Your Dealer Brake System warning light A “Systems Initializing… Continue Driving” message also appears. I have photographic documentation of these dashboard messages. This sequence creates a significant safety concern. The sudden jerk and power loss can occur while the vehicle is in motion, and the subsequent disabling of the Honda Sensing systems (Collision Mitigation Braking, Adaptive Cruise Control, and Road Departure Mitigation) leaves the vehicle without those critical driver-assistance features. Because this involves sudden power loss and the disabling of safety systems, I consider the issue urgent and ask that it be prioritized.

All warning lights came on whilst driving. Scheduled a diagnostic at the dealership. Dealership confirmed the head gasket had blown due to the design flaw of the coolant pathway between cylinder #2 and #3. This is a common problem with this engine. Vehicle is out of warranty. Now faced with a big repair bill.

FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: ASSIST
The dashboard lights up”brake” and the car slams on the brakes unexpectedly on occasion- and sometimes for no known reason. This has happened countless times. yesterday it happened again while driving on the intersection at 70 mph . there were no vehicles in front of me and I was not changing lanes, but the car slammed on the brakes, making the car behind me almost rear-ended me & cars having to swerve around my vehicle. This is very unsafe and it needs to be addressed and corrected by Honda.

2 weeks ago. All of my warnings and lights for my car came on. We undid my battery, charged it and did it again. The lights went away and about 3 days ago they came back on. Now my car is overheating and the system is reading wrong.

ENGINE, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The head gasket is failing and causing the engine to overheat and misfire. Its a repeating issue I see online and have taken it to a certified Honda mechanic multiple times. The first diagnosis stated that the biggest issue was the fuel injections. Now this second diagnosis shows the head gasket. It poses a great danger especially in highways, as it causes the car to decelerate on its own and rattles as if it's losing power. It will overheat when it is idling. The check engine light turned on a week after purchasing the car from a local dealership, and the dashboard lights were wiped from the system prior to buying the car a year ago. Now I'm looking at over 7k in repairment costs while still financing a car I believed was reliable.

POWER TRAIN, ENGINE, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
I am reporting a safety concern involving my 2018 Honda Accord. I purchased my vehicle used in January 2024 at approximately 90,000 miles and have kept up with the recommended maintenance during my ownership. At approximately 120,000 miles, a Honda dealership diagnosed head-gasket failure with coolant intrusion involving cylinders 3 and 4. Before diagnosis, the vehicle experienced rising engine temperature while idling, coolant loss, jerking during acceleration, numerous warning lights, and severely reduced acceleration. The problem progressed to loss of power and stalling while driving and slowing/stopping, requiring me to place the vehicle in Park and restart the engine to continue driving. The vehicle also developed unstable RPMs and engine surging while in Park. Honda performed a cooling-system pressure test and borescope inspection and confirmed coolant intrusion. Head-gasket replacement cost approximately $5,000. I contacted American Honda (Case #16533411), but goodwill assistance was denied because the vehicle is outside warranty and Honda stated it had no Honda-dealership service history. I am reporting this because the head-gasket failure resulted in loss of propulsion and stalling while operating the vehicle, creating a serious safety concern.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
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.

In July 2026, our 2018 Honda Accord required a head gasket replacement. Prior to the diagnosis, the vehicle began experiencing rough starts and engine misfires. While driving, the car suddenly lost power and would not accelerate beyond approximately 10 mph. After returning home and restarting the vehicle, its performance temporarily returned to normal; however, the engine continued to idle roughly. We had the vehicle scanned, and the diagnostic result indicated a misfire in Cylinder 3. The vehicle was taken to our local Honda dealership, where we were informed the head gasket failed and needed to be replaced. Given that the vehicle has fewer than 140,000 miles, we do not believe such a major engine repair should be necessary. Over the past 25 years we have owned multiple Honda vehicles, including Accords, Civics and CR-Vs well over 200,000 miles with our current 2008 Honda CR-V having more than 344,000 miles. None of these vehicles have ever experienced a head gasket failure or similar engine issue. We have never had such a significant costly repair, over $6,000. We are extremely disappointed that our 2018 Accord required such a significant repair at relatively low mileage. We have also learned of allegations in ongoing litigation Bissell v American Honda Motor Co, involving similar head gasket issues affecting Honda vehicles. Based on our experience and the number of reported complaints, we believe Honda should issue a recall, provide warranty coverage or reimburse affected owners for repair costs whichever benefits the customer. We respectfully request that Honda review our case and consider reimbursement or goodwill assistance for this unexpected and expensive repair.

While driving, my vehicle began shaking/rough running and the check-engine light came on. Multiple warning lights and system warnings appeared on the dashboard, including the brake system, steering, traction control, and TPMS warnings. The vehicle experienced noticeable shaking and reduced/abnormal performance. I am concerned that this may be a safety-related defect because multiple vehicle systems are being affected.

POWER TRAIN
My fiancé was driving my 2018 Honda Accord when the vehicle suddenly jolted violently while accelerating up a bridge. Immediately afterward, multiple warning lights, including the check engine light, came on and the vehicle lost all power. Thankfully, she was able to coast down the bridge and pull into an empty parking lot. This was extremely dangerous because the vehicle lost power while being driven and could have caused a serious accident. After turning the vehicle off and restarting it, the car appeared to operate normally. Because the issue was intermittent, I initially suspected the battery. I had the battery tested multiple times, but it was fine. Since the problem continued, I took the vehicle to a Honda dealership. They diagnosed a blown head gasket and estimated the repair would cost approximately $6,000. The vehicle is only worth about $6,000, making the repair financially unreasonable. Apparently this is a known/common issue with 2018 Honda Accords. I requested Honda goodwill assistance, but Honda declined. I then took the vehicle to a second independent repair shop for another opinion. They advised that the head gasket needed for the vehicle was on back order and therefore could not provide a repair estimate. The fact that this replacement component is currently on back order is concerning and raises further questions about how frequently this repair is being needed. If Honda cannot keep enough replacement parts in stock to service affected vehicles, it further suggests that this may be a widespread issue that deserves additional investigation. The vehicle is available for inspection upon request and has been inspected by both a Honda dealership and an independent repair shop. I am extremely concerned that a vehicle can suddenly lose all power while being driven and that a repair for a known/common issue costs nearly the entire value of the car. I believe this issue warrants further investigation by Honda and consideration of a recall or assistance.

At 92,156 miles, my 2018 Honda Accord Touring (1.5L Turbo) suffered a catastrophic structural head gasket failure that caused dangerous engine instability while driving. The failure first manifested with a sudden eruption of multiple warning lights across the dashboard while the vehicle was in motion. Following a subsequent startup after a doctor's appointment, the vehicle began shaking violently due to immediate engine misfires. Driving a vehicle that is actively shaking and suffering from cylinder misfires in live traffic creates an unpredictable stall risk and an immediate safety hazard to myself and surrounding motorists. A certified technician at Ourisman Honda of Woodbridge pressurized the cooling system and physically confirmed that engine coolant is actively leaking directly onto the engine cylinder walls (Cylinders 1 and 2) due to a structural head gasket failure. This is a severe design defect that causes unexpected powertrain disruption on public roads.

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.

Major safety issue will lead to loss power and visual hazard for cars on road. 2018 accord 1.5 has a coolant leak in cylinder 2 and three via scope verified , shop said it needs a headgasket. It had misfire codes on scanner and shakes when start up. This will be potentially big issue if motor blows up on free way from overheating. Honda corporation won’t do a replacement for the good faith because the car has not been to “Honda” for service.

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.
