The components and systems that are failing and malfunctioning in my 2018 Honda Accord are the engine, head gasket, fuel, injectors and turbo. While in motion, the car jerks and has issues with acceleration requiring the safety hazard lights to be come on and I-??m unable to keep up with marked speed limit while traveling due to the sluggishness of the vehicle. The majority of these issues have been confirmed by a Honda dealership as well as another car shop. There are several warning and safety hazard lights that come on and go off the dashboard. Many times, I have to pull on the side of the road due to not being able to drive this vehicle.

While waiting for the recalled parts to be in stock for the fuel pump module, my car starting running rough and going into limp mode several times a day. Thus causing near accidents with my children in the vehicle. After getting the fuel pump module recall fixed I asked and had to pay for a diagnostics test to see what was causing the car to do this. We were told it was the fuel injectors and were quoted $2000 to replace those. That was done 4 days ago at the dealer, and it happened again yesterday! We took the car back to the dealer today and they have just informed us we need to replace the head gasket & turbo and had a coolant leak causing these issues?! Why that was never seen in the original diagnostics test nor a problem 4 days ago, but after spending $2000 we did not have to keep our family and others safe, we are now being told it will cost over $5000 to fix these now issues. We can-??t afford that and now I don-??t know what I am going to do! Honda needs to step up to the plate and take some culpability here and be responsible for what clearly appears to be a much needed recall for 2018 Accords! This is ridiculous. And for the service advisor to tell us this happens all of the time to these, if not daily, should speak volumes!

February 2025 All the warning light on in my car came on. I took it Honda where they had me pay $250 for a diagnostics. At 85K miles, that's when I found out a had a blown head gasket and need a replacement.They also suggested a new fuel injector. They quoted me $7,000. My warranty just expired. This was my car and I didn't know anything about warranties and renewals. I always go to go Honda for my services and I had just visited a few weeks prior and they didn't see anything wrong my car. The Honda service guy told me to car it to the nearest Carfax because my car and sell it. I was so distraught. Now I'm trying to figure out how to get the money to pay for this.

Three times, while driving, the car went into limp mode and would not accelerate. Had to pull over, turn car off, and back on to fix the issue. Have had it looked at and they have mentioned engine coils and a new control module. Had it at the dealership in January and they did their full inspection and to fix fuel pump recall and didn-??t mention any issues regarding this.

Christmas Tree dashboard with all lights on appeared a few weeks ago. Took car to auto shops twice. First time I was told coil 1 for cylinder 1 was misfiring, replaced with new coil. Lights did not go away, got my codes read again and was same error message of coil 1 misfire. In the past week car would not accelerate past 15mph after start up. I was immediately concerned it was a head gasket issue since that is a very known defect for my exact make and model of vehicle. Took into my Honda Dealership where I purchased my Accord brand new. Was just told Fuel injectors need to be replaced even though vehicle has been maintained properly. To me this seems this is directly correlated with the current fuel pump recall issue, I asked the service advisor if that was the case and she said she-??d get back with me, and that she-??s currently waiting to hear back from my Lifetime Powertrain Warranty company (Fidelity Warranty Services) to see if the fuel injector replacement is covered by them. If this make and model has time and time again been known to have faulty fuel injectors and head gasket issues that directly put the drivers safety at risk and end up causing thousands of dollars in repairs, Honda needs to take responsibility for rushing out vehicles without properly testing them first. If fuel injectors are not covered under my warranty, I will be contacting American Honda to assist me with the cost of the repairs.

About two weeks ago, I could have been killed on the New York State Thruway when my 2018 Honda Accord suddenly lost all power. One moment, I was driving normally-?"then, without warning, my check engine light came on, I had zero ability to accelerate and was forced to pull over as my car rapidly lost speed. II had my vehicle towed to Morehead Honda where they ran diagnostics and told me my car needed nearly $6,000 in repairs due to coolant leaking into the engine, which caused cylinder misfires and valve damage. But here-??s the kicker-?"this same issue has happened to other Honda Accords of the same model year, yet Honda refuses to recognize it as a widespread problem. Morehead Honda admitted to me that they-??ve seen this issue before in other 2018-2020 Honda Accords and 2017-2018 CR-Vs. In fact, they said Honda quietly fixed the problem in newer models (2021+)-?"but they still won-??t acknowledge it as a defect in mine. That means my engine failure is not some one-in-a-million fluke-?"it-??s something that has happened to multiple owners of the same model and year. But Honda refuses to take responsibility, leaving me on the hook for an absurdly expensive repair. Many others have had the same or similar issues. Below are some: 2017-2020 Honda Accord owners who have reported coolant leaks, cylinder head cracks, head gasket failures, or related issues: 2018 Accord 2.0T owner blew a head gasket, with a potential cracked engine block. The dealership diagnosed the issue on cylinder #3, with coolant mixing into the engine oil. A 2018 Accord EX-L 2.0T owner experienced a coolant loss leading to a blown head gasket and coolant leaking into cylinders 2 and 3. A 2018 Accord 1.5T owner had dashboard warnings and the car failed to accelerate. The dealership diagnosed a blown head gasket, with coolant leaking into cylinders 3 and 4. A 2020 Honda Accord owner suffered a blown head gasket at 58,000 miles. The dealership confirmed it was the fourth such case they had seen.

I was driving to college all of a sudden the car went into limp mode. Before I could do anything I called Honda and they didn-??t answer so I personally drove it to the Honda dealership 10 minutes away from me. They inspected the vehicle and told me the head gasket has been blown. The car has been garage kept never abused and they are charging me $6,100 for the repairs. It-??s been a common issue for the 1.5t engine of the Honda accord and they have yet to acknowledge their manufacture defect. Please do something about this I have to pay for college how in the world am I gonna have money to pay $6,100 for a repair cost.

Head gasket replacement Fuel injectors replacement Driving my car started sputtering and jumping. I took to Honda South to get it diagnosed. I was told it needed fuel injectors and a head gasket. Also to get other things done since the engine will taken apart (drive belt, timing belt, water pump). I started a conversation with a service mechanic in the lobby and told him my issue. He told me the 1.5 turbo engine has problems with the head gaskets and they see a lot of them.

The contact owns a 2018 Honda Accord. The contact stated that the vehicle was idling rough when started. The vehicle was taken to an independent mechanic to be diagnosed, and the contact was made aware of misfires in cylinders #1 and #4. The contact was informed that the coil packs needed to be replaced. The vehicle was repaired; however, the failure persisted. The contact stated that on another occasion while driving 65 MPH on Interstate 75, the vehicle lost power. Several unknown warning lights were illuminated. The contact merged to the side of the road to exit the interstate. The vehicle was then taken to a dealer and was diagnosed with misfires in cylinders #1 and #4, and the coil packs needed to be replaced. The dealer notified the contact of the recall for the fuel pump, and the vehicle was repaired for the most recent failure, and the recall repair was performed. The contact stated that the failure persisted, and the engine needed to be replaced. The manufacturer was not made aware of the failure. The failure mileage was approximately 88,000.

My car is having the same issue as the new recall on the 2023-2025 Honda Pilot sport utility vehicles (SUVs), 2022-2025 Acura MDX Type-S SUVs and 2021-2025 with the power loss and my car is stalling. Sometimes when I turn my car on, put it in drive, impress my gas pedal it will not go. I have to cut my car off, wait for about 30 seconds, restart it and then it will go.I took my car to Honda in Tifton Ga and I was told that it was my fuel injector. I was given code P0301 from Langdale Honda in Valdosta ga. I was quoted $1600 to fix this issue which I do not have. I-??m currently having this issue and I-??m sure it-??s many others.

My Accord HG Issue Well my 2018 Honda Accord Sport 1.5t that I-??ve owned for not even 2yrs and | bought it with 54k and now has only 59k on it and has started acting up the last few weeks!!! It went into limp mode once a few weeks ago outta nowhere and just shut my car off and so I then turned it off and back on and it reset. Well fast forward a week later and limp mode again and so l hooked it up to a OBD scanner and said misfire cylinder 3 so l replaced the spark plugs and at that point. I then noticed the oil was low and due for a change and it smelled like straight gas. So drove a lil bit and limp mode again and again it said misfire cylinder 3!!! So then I decided to swap the coil pack and checked the spark plug again and seemed normal, also I noticed my coolant was below minimum so I filled it hoping that was my issue and cruised later and no limp mode so l thought I that fixed it, but one thing I noticed was at higher rpm-??s in Ist gear the exhaust would backfire a lil but no limp mode. Well the next day I went cruising for a few hours and it was good all night but then on my way home it went into limp mode again!!! So Saturday was when I filled my coolant and Sunday after cruising I checked my coolant and it was still at full, well l checked it again on Monday night and it-??s now in the middle of full and minimum and the new fresh oil smells like straight gas and also went down a lil!!! So then I had a buddy who-??s a mechanic with borescope look at the cylinders and cylinder 3 was not great 4 had a lot of carbon build up and liquid in which looked like antifreeze and I also did another test that confirmed it was the head gasket!!! This is VERY DANGEROUS and a SAFETY issue BIG TIME because I was on the highway and all of a sudden I lost power at 70mph and couldn-??t accelerate and had to pull over on the highway which was even more dangerous and had to shut it down and then it would reset and I was able to drive until it happened again!!!

My 2018 Accord Sport 1.5 blew the head gasket at 118,000 miles. I've always taken good care of the car-?"it's never been damaged or abused, and I-??ve used the highest quality engine oil for every oil change at 10k miles, even though Mobile claims it can last up to 25k miles. One morning, on my way to work, I started experiencing a misfire as I pressed the gas when the light turned green. Suddenly, the car lost all power, and I had to turn on my hazards and coast to the shoulder. After turning off the engine and waiting a few minutes, I was able to start it again and barely make it to work. I initially suspected a bad spark plug or coil pack, so I replaced all four plugs and coil packs. The fix worked for a day, but then the misfiring returned. The code was reading -??cylinder 4 misfire, -?? so I decided to take it to Honda for a diagnostic. They called me after the test and informed me that the head gasket for that cylinder had blown, quoting me $5,000 for the repair. I refused to pay that and decided to tackle the job myself instead. The dealership wanted to drop the engine and disconnect everything, even suggesting a transmission fluid change, despite the fact that I-??d had it serviced just 15 to 20 thousand miles ago. After doing some research, I found a replacement head gasket for only $35 and went ahead with the repair. Everything was going smoothly until I hit a snag with the crankshaft pulley nut, also known as the harmonic balancer nut. Despite numerous attempts, it just wouldn't budge. I tried using a 1,200 ft-lbs 1/2-?? pneumatic impact, then switched to a 1,600 ft-lbs 1/2-?? Milwaukee battery impact, and even got a pulley lock to secure it in place with a breaker bar. Unfortunately, the pulley is poorly made! When we over-torqued it, we ended up breaking the pulley even more. We also tried a torque multiplier, which only made things worse. Now, the only way to get that stubborn nut off is with a 2,000 ft-lbs impact, but I still haven't managed to break it free.

At approx 10pm, vehicle was moving at a steady speed of 70mph on urban highway on New Year's Eve. Without any indication or warning, the car stalled/had loss of power for about 1-2 seconds and recovered and then about 1-2 minutes later stalled again and recovered. No dashboard lights ever came on. I thought maybe the clutch was failing again. I immediately got off the freeway to find a safe place to call for tow. As I drove to parking lot, my motor made a loud, uncoordinated, rattling noise which is towards the left side and near the engine cover. I thought it might be the serpentine tensioner because only the belt only had been replaced in May 2024. The rattle gets louder with high RPMs. After reviewing service records, oil change on 04/18/24 is the first mention of valve cover leak, and oil change 12/23/24 indicates possible rear main seal leak, residue around rear main cover which made me suspect gasket failure. The dealership denied the fault lies with tensioner or clutch and said the knocking sound is from the lower portion of the motor - possibly a faulty knock sensor - and the engine would not be disassembled to provide a more specific diagnosis. The dealership said a replacement engine is needed. No diagnostic codes or other specifics were provided. Dealership replaced fuel pump module per recall protocol. My and my grandchild's safety were jeopardized because my malfunctioning vehicle could have created a deadly traffic hazard among NYE celebrants who may have been driving distracted or with impaired cognitive function. In the past when my vehicle had stalled, it would lose power and I would have to coast off the freeway or to the side of the road. In those instances, my car created a traffic hazard & congestion for the vehicles behind me and toward the side that I was trying to exit.
