2018 HONDA ACCORD Complaints

Bad engine, and Honda knows it, and they will not fix my car. I have reported this to Honda America and Honda Japan. Cylinder 2 and the head gasket went bad at 77,000 miles. I am disabled and a full-time student. This was diagnosed at Honda Autonation in Columbus Ga. I even asked whether they would take it as a trade-in. They said no, so my next step is to file a class action lawsuit against Honda when they should have just accepted responsibility and fixed my car. There is a forum on Reddit and Facebook with 1000s of people with the same problem.

While on the highway, going approximately 60-65mph, lights on my dashboard suddenly lit up and turned right back off as my car began to decelerate on its own. After I was able to get my car off to the side of the highway, I had to have it towed home as it was inoperable. I had it towed to my preferred auto shop and they discovered the engine had failed at only 84,000 miles. The total cost was approximately $8,600. After a bit of research, it seems this is a known issue for this engine model from Honda and nothing has come of it so far.

2018 Honda Accord EX-L with the 2.0L turbocharged engine. At approximately 113,000 miles the head gasket failed, allowing engine coolant to leak into cylinders 2 and 3. Symptoms included repeated cold-start engine misfires (diagnostic codes P0302, P0303, P0300), illuminated check-engine light, intermittent loss of power / limp mode, and gradual loss of coolant with no visible external leak. The failure was confirmed by an independent mechanic as a blown head gasket between cylinders 2 and 3. This matches a widely reported design defect in Honda's 1.5L and 2.0L turbocharged engines (2016–2022 Accord, Civic, CR-V, Acura RDX/TLX) that is the subject of federal class-action litigation. The sudden power loss this defect can cause while driving presents a safety risk. Repair cost approximately $6,000, paid out of pocket, with no recall in effect. Requesting NHTSA investigate a potential design defect and recall.

Was driving onto the interstate when car hissing sounded ,then car cut out and all my dashboard warning lights were on a loop the code is turbo boost but car died and no safety features would work i just barely missed being completely crushed by 18 wheeler

My vehicle will NOT drive past 20 MPH,it randomly goes into limp mode with traveling ! I’ve have it tested multiple times and no one seems to know what the issue is !

Two premature blown head gaskets and warped cylinder heads, the first at 95,000 miles, while driving on the freeway the car started to shake and all warnings lights came on, luckily I was not far from the dealership and took it right in. The second at 137,000 miles. The first repair was done at Honda of Concord dealership and was covered under the extended warranty. Warranty has since expired and the issue has happened again. This time Honda is recommending that I replace the engine, while denying my request for a goodwill repair. The dealership quoted me $10,000 for repair, and my car is maybe worth only $13,000. Honda knows that there's a design flaw with the 1.5L engines, but won't take any accountability for it.

I just replaced the head gasket 3 years ago. I was on my way home & all the lights in the dash came on. Took it to the local dealership. Once again it’s the head gasket.

I own a 2018 Honda Accord. While driving 30 MPH the vehicle experienced head gasket failure/engine failure-trouble. The vehicle lost automotive power and decelerated to 5 MPH. I was able to drive safely. The engine light was illuminated as well as all dashboard lights were illuminated. The vehicle was taken to the local mechanic immediately, where it was diagnosed with a misfire in cylinders #2 a computer code malfunction, and then taken to dealer immediately from there. Dealer ran and found same code. found a blown head gasket. (Charging me a diagnostic code for same reading.) The vehicle was repaired privately as dealer wanted more than $1000. more to do the work. The manufacturer was contacted and assisted with the cost of the repair. The manufacturer confirmed there was no warranty coverage on the vehicle. I am out $4524.66 in repairs due to an issue that Honda is aware of and had done nothing to rectify.

There are 13 alerts showing on the instrument panel for various systems not functioning, along with accompanying yellow dash lights such as tire pressure, ABS, brake system, traction control, ACC, and LKAS. Systems not available include, ABS system, Adaptive Cruise Control, Road Departure Mitigation, Auto High-Beam, TPMS, Electric Power Steering, plus several others. These alerts first started January 2026 and occasionally would disappear; however, over the past few months the warnings have become constant. The vehicle has approx. 120,000 miles. Due to TPMS not functioning, I am not given a warning when a tire has gone flat/blown while driving as the tire pressure light is always on the dash. The only warning I am provided is the sound/smell of the rim dragging along the road to notify me the tire is flat. This poses a risk to myself and others by creating an emergent situation requiring me to pull over rapidly. Another incident occurred when ACC was enabled (at a time when the alerts had been appearing on and off). Cruise control set at 70 mph when suddenly the above mentioned alerts reappeared and ACC system became unavailable, leading to unexpected deceleration on the highway. This poses a risk to myself and others as it creates unpredictable driving patterns, unbeknownst to the driver. Initially I replaced the battery with no resolution of the issue. I later discovered maintenance code displayed by the vehicle was C003A-62 for Right Rear Wheel Speed Sensor Circuit Failure (circuit short to ground or open). The mechanic recommended replacing the right wheel hub assembly as this was suspected to be the cause of failed circuit. When that repair lasted no more than 10 mins before the warnings reappeared, the right rear wheel speed sensor itself was then replaced. Similarly, this did not fix the issue. I have not sought additional service due to repair costs beginning to add up with no resolution. Based on the history of reports, this issue does not seem uncommon.

On 2-252026 my wife and I were driving on highway I-15 in California when the car started to accelerate, decelerate and jerk and the engine light came on. It was very scary because we were on a major highway driving around 60 MPH and cars were behind us when the deceleration happened. We could have been hit by cars traveling behind us or either we could have caused a major accident. We had to get off the highway and have the car towed to Honda for assessment. There was no engine light warning or service warning from Honda prior to this happening, it just randomly happened. The car was repaired at a Honda dealership and they said there was a leaking head gasket on cylinder number 4. When we looked up information regarding this head gasket failure we saw that other Honda cars have had the same problem and Honda is currently involved in lawsuits regarding this leaking head gasket on cylinder number 4.
