Owners have filed 2,923 complaints
about the 2018 Honda Accord with NHTSA between 2017 and 2026.
The largest single group is the engine & cooling.
Across this model's run it ranks 4 of 33 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 100
Against the median year of the Honda Accord. 50 means typical for this
model; 100 means roughly double.
Severity — 20
4% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 100
63% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

NHTSA investigations into the 2018 Honda Accord
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.
On February 21, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE22003) to assess reports of inadvertent activation of the Collision Mitigation Braking System (CMBS), an automatic emergency braking (AEB) system, in model year 2017-2019 Honda CR-V and 2018-2019 Honda Accord vehicles. The reports allege that activation of the AEB system occurs while driving with no apparent obstruction in the vehicle's forward path, resulting in sudden vehicle deceleration. Honda indicated that they were aware of a total of X,XXX reports that may relate to the alleged defect. Hon...

Recalls on the 2018 Honda Accord
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

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.

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.

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.

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.

ELECTRICAL SYSTEM
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.
