2018 HONDA ACCORD Complaints

Pulling out in front of High Speed Traffic, Engine went into Safe Mode with Check Engine Light. Fortunately a car at high speed avoided rear ending my car. Upon evaluation, DTC Code P0303 (Cylinder 3 - Misfire) was present. Coils and Spark Plugs were changed but car was still misfiring. Honda has a Warranty for 150k/ 10 year on Fuel Injectors but this VIN was not on list based on Honda Service Department. The Honda Service Department evaluated and Car has Head Gasket Leak in Cylinder 3. This is a widely known problem reported on many Honda Owner websites and Honda Service acknowledged it was an issue but is not a “Recall” despite the potential Safety Risk on the Road when car goes in to Protect / Shutdown Mode. The nature of this issue occurring on a well maintained car with 147k miles that is 8 years old and not being a Recall and a Safety related item is being reported by me as me and my family could have been impacted by a rear end collision as car shut down / protect mode. This could and likely has occurred to other owners and possibly attributed to accidents and Safety of passengers. Honda wants over $11k to repair the car which includes Fuel Injectors / Plugs / Coils / New Head as they reflect old head can’t be used even if machined / Head Gasket. This issue is a Safety related issue and should be a Honda Recall as the Head Bolts are a known design issue causing premature failure of the Head Gasket. Submitting this to document my incident, protect the public driving this model and year and hopefully providing information to warrant a recall so that all repairs will be performed under Recall Warranty. Also to protect the public from a Honda Accord Safety issue for 2018 Honda Accord LX.

I was driving down a 45mph street when my car shut down, complete power failure. Dashboard lit up with all kinds of warnings. It had to be towed to the nearest shop.

We’re driving home when the vehicle suddenly had a significant reduction in power and the car would not accelerate beyond 5 mph. Honda calls it “limp mode”. I was approximately 2 to 3 miles from home. Approximately 20 vehicles swerved passed us at normal road speeds of approximately 50 mph. The only warning light that came on was a flashing “check engine” light. The vehicle towed to Elk Grove Honda, I initially thought it may the turbocharger because I could hear a grinding sound emitting from that area. EG Honda diagnosed the issue as coolant leaking into the cylinder, which caused the misfire from a faulty head gasket. It is understood this faulty head gasket issue is part of a California class action lawsuit related to 2018-2022 Honda 1.5L turbocharged VTEC engines.

The dashboard on the vehicle lights up with multiple error notifications. This puts the vehicle in limp mode. Indicates emissions errors, check engine, lane mitigation, brakes, control system. Per different customers this fault is being caused by either faulty fuel injector, miss fire, bad ignition coils, damage head gaskets, or turbo mechanism faulty. My vehicle has 70,000 miles and others in the chat have less miles that are having similar problems. Head gaskets should not fail so soon with proper maintenance. My obd2 scan code is miss fire which could Indicate faulty spark plugs, coil, injector or headgasket. For a vehicle at 70,000 miles this shouldn't happen. Vehicle has been maintained as the manufacturer recommendations

The vehicle began to overheat while traveling at fair speeds (35mph) on state road. Thermostat reading increased to H and vehicle note read “vehicle overheating” please park car. Car temperature read over 104 degrees Fahrenheit. No check engine light present. Vehicle was parked and turned off to cool.

2018 Honda Accord with blown head gasket. Vehicle has a 1.5L turbo charged engine and 100,000 miles.

The head gasket failed which caused the vehicle to stall out while driving which poses a safety threat to the driver and others due to other vehicles possibly colliding with the vehicle when stalling out. Also, this issue cause the warning light of the engine overheating, which required me to pull over while driving to prevent additional damage to the engine. The vehicle was taken to a nearby dealership for repairs that cost $3,898.91. Upon research, this is a standard issue with this year, make, and model that Honda has refused to address through a recall.

I am experiencing an ongoing issue with my 2018 Honda Accord LX 1.5L where multiple warning lights on the dashboard illuminate simultaneously without warning, often described as the dash lighting up “like a Christmas tree.” These lights include (but are not limited to) collision mitigation braking system, road departure mitigation, adaptive cruise control, power steering, and other safety-related systems. The issue appears to occur intermittently and without a clear cause. When this happens, several driver-assist and safety features become disabled, which raises serious safety concerns while operating the vehicle. After researching this problem, I have found numerous reports from other Honda Accord owners experiencing the exact same issue across various online forums and communities. Many of these individuals have also been advised to file complaints with NHTSA due to the widespread nature of the problem. This appears to be a potential systemic or electrical issue that affects multiple critical safety systems at once. I believe this defect could pose a significant safety risk and should be investigated further.

When Tpms light comes on, all safety features including cruise control become disabled. Lane assist and collision safety features become disabled. On top of that, I have had Honda look at my rear end after they replaced a rear upper control arm after being in a ditch and at 246,000 current miles, I have replaced my tires 16 times due to the rear tires ripping the tread off between 10-15k. If there was nothing else wrong, why have I spent between $10,000-$15,000 miles on tires? I have had numerous alignments at Honda and elsewhere. Marion Honda claims it’s normal! I was told I can put adjustable control arms on. I have met other Honda accord sport 1.5t owners with 50k miles on one set of tires, yet I can’t get more than 15k on the rear tires. Clearly something is bent or incorrect currently I am re replacing the upper control arm.. They say the alignment rack does not flag anything. I have bought between Goodyear, Michelin, and Pirelli tires they also replaced a turbo, only for a few months later to have a pressure problem that Findlay Honda found I was missing an oring in the turbo or intercooler. How? Orings do not call out. Fast forward 18 months and another bad turbo on this lemon!

I have bought this car new in 2018, The issue that I’m having is that ..I’ll be driving on the highway or local my car will brake on its own without any hazards in front of it . It’s very dangerous it almost caused me an accident on the highway .
