2018 Honda Accord: engine stalls while driving

Filed Oct 6, 2026 · Driver assistance, Electrical · NY

Reporting fraudulent safety recall compliance & hazardous repair by Honda of Manhasset (Invoice #317524). 1. Recall 23V‑858 (Fuel Pump): Dealership registered recall as completed & Service Manager verbally insisted it was done. However, my vehicle's continuous dashcam footage proves fuel pump replacement was NEVER performed. Faced with video evidence, the advisor admitted work wasn't done because the part was out of stock, claiming a "billing error." Invoice reprint says "RECALL NOT PERFORMED, PART NOT IN STOCK" yet they initially processed it, leaving an immediate engine stall risk. 2. Software Campaign & Radar Failure (Service Bulletin 21-068): Dealership performed mandatory Honda Sensing update for Millimeter Wave Radar, wiping old calibration parameters. Per Bulletin 21-068 (Pg 3), the repair is NOT complete until the radar is re-calibrated & the warning light disappears. Instead of performing the radar aiming, the technician left safety systems locked with DTC P2583-76. I authorized a $215 diagnostic fee, but despite having the scanner connected during the update, the technician failed to follow Honda's official troubleshooting protocol to resolve the code and finish the calibration, returning the vehicle with disabled emergency braking features. 3. False Physical Diagnosis: Staff verbally claimed the radar bracket was "bent" to blame a prior impact. Challenged for physical proof, they admitted performing NO physical inspection, stating they "assumed" it was bent solely because the scanner showed P2583-76. This is a blatant lie to cover up their failure to follow factory troubleshooting workflow for this specific DTC, which dictates aiming the radar, not fabricating physical damage to justify leaving the safety repair incomplete.

My car keeps losing power suddenly! Sometimes it has even started to stall while driving. Also the electrical menu has tons of errors and isn't working. There are several recalls on Honda Accords for the fuel pump and the vehicle assistance module but my vin doesn't show up.

I am reporting a recurring safety and mechanical issue with my 2018 Honda Accord 1.5T, which currently has approximately 128,900 miles. My vehicle has been experiencing shaking/rough operation and multiple warning lights while driving. Diagnostic scans have shown P0301 – Cylinder 1 Misfire and U0401-68. The ignition coils were replaced with original/OEM parts in an attempt to correct the issue. After the repair, the warning lights went away temporarily, but within several days the same warning lights and symptoms returned, and the vehicle again showed the P0301 cylinder 1 misfire code. I am concerned because the vehicle continues to shake and operate abnormally despite the repair. I have learned that Honda has addressed cylinder-head-gasket concerns involving certain 1.5L turbocharged Accord vehicles, which may cause engine misfires. However, I have not had my vehicle diagnosed with a defective head gasket, so I am not claiming that this is definitely the cause of my vehicle's problem. When I checked my VIN through the federal safety agency, it showed 0 unrepaired recalls. I am submitting this complaint so that the federal safety agency has a record of the recurring problem and can determine whether my vehicle's condition may be related to a broader safety defect affecting 2018 Honda Accord 1.5T vehicles. I am concerned about the possibility of the continued misfire causing loss of engine performance, loss of power, stalling, or otherwise making the vehicle unsafe to operate if the underlying problem worsens. I have photographs of the diagnostic scans documenting the codes and records showing the previous repair.

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.

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.

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

The vehicle suffered a sudden, severe structural head gasket failure causing coolant to flood the combustion chambers. This results in violent engine stalling, limp mode, and complete loss of propulsion while driving at highway speeds, creating a severe traffic hazard. The manufacturer is actively tracking this conjoined cylinder failure but refusing to issue a safety recall for the defective engine block layout while their local dealerships dangerously misdiagnose the problem and leave customers with unreliable and unsafe vehicles.

I own a 2018 Honda Accord equipped with the 1.5L turbocharged engine. At approximately 53,666 miles, the vehicle developed a rough idle, engine shaking during startup, intermittent check engine light, and a cylinder 1 misfire code (P0301). I took the vehicle to a Honda dealership for diagnosis. The dealership confirmed coolant intrusion into cylinder #1 after performing a cooling system pressure test and borescope inspection. The dealership determined that the engine has a failed head gasket and provided a repair estimate exceeding $6,000. The dealership advised that the vehicle should not be driven because coolant entering the cylinder can cause further engine damage, loss of power, engine stalling, overheating, or complete engine failure while driving. I believe this is a safety concern because the engine may misfire, lose power, or fail unexpectedly during vehicle operation. A major engine failure at only 53,666 miles is not consistent with normal wear and tear. I am submitting this complaint so that the federal safety agency can investigate potential defects involving coolant intrusion, head gasket failure, and cylinder misfires in Honda Accord vehicles equipped with the 1.5L turbocharged engine.
