2018 HONDA ACCORD Complaints

Vehicle had a sudden loss of power. Pulled over on highway had to restart. Engine warning said Emission system problem. Had diagnostic done several codes PO300,PO301,PO302,PO303,PO304,PO172. Problem seems to be similar to the service bulletin 22-002 dated Feb 18,22 for the Honda Accord 2015-2016. It seems to be a known issue with this engine. Honda should take care of this safety issue.

The contact owns a 2018 Honda Accord. The contact stated that while driving 30-35 MPH, the vehicle overheated and stalled. Several unknown warning lights were illuminated. The contact pulled over and turned on the hazard lights. The vehicle was taken to the local dealer on three occasions and was diagnosed with a blown head gasket and engine failure. The vehicle was repaired, but the failure recurred. The vehicle was not repaired. The manufacturer was contacted and provided financial assistance. The failure mileage was approximately 70,000.

07/30/25 - Over the course of 1 week, I have received three dashboard warnings "Supplemental Restraint System Problem. See Your Dealer" It goes away once car turns off. Honda of Katy states to bring in when alert still on dashboard (which will disappear when car turned off) but quoted will be required to sign a $215 diagnostic fee. No charge if it is just an error code. But $215 can be used toward repair. This is a SAFETY ISSUE and should be a SAFETY RECALL as owners should not need to pay for manufacturer DEFECTS. I can not afford to fix since still paying off the known issue of fuel injectors failing but not yet SAFETY RECALLED. Please help.

I had been driving down highway and all of a sudden my car put on brakes hard. Thank goodness no one was behind me. I had dealer turn off that feature so it wouldn't happen again. I still experience my brake light flashing when nothing in road to brake for but doesn't brake on its own. Issue having now is issues starting car and once it starts I recieved a collision mediations issue pop-up on display saying see dealer now. Cruise control issue, and on dash has traction control saying ignitionating continue driving. The braking issue started right after purchase in 2018. The starting issue started yesterday 7/25/2025.

This is regarding TSB 21-087, Warranty Extension for 2018 Accord Paint B-757P Still Night Pearl. I was not informed in writing as per required customer notification in 2001. The extended warranty was for 7 years from date of purchase with no mileage limit. When I noticed the paint peel on the roof seams on the left side and right side of the roof, I asked the local dealership today on 7/25/2025. They said I was a few weeks past the expiration date and I had to contact American Honda. While at the dealership getting maintenance performed, I contacted them via chat and they directed me to call instead. I called Honda and they said once the expiration date has passed, there was nothing to be done. I asked for good will and she declined. They will not provide email of incident, as per my request, from discussion but did open case and assigned a case number. Honda stated my only recourse was to pay for damage out of my pocket or wait to see if Honda will possibly extend the warranty and that it was my responsibility to contact them since they will not provide any notification again. So, my vehicle will continue to rust from the paint peel on the roof on a daily basis in the Florida sun. Or I have the option to pay out of pocket now and, if warranty extension approved request reimbursement.

Car had a rough start one morning. The engine light came on. All safety features were disabled. I took it to the car dealership that same day (sunset Honda San Luis Obispo California) they got back to me and said the car had head gasket failure. The dealership was the only person to do any meaningful mechanical work ( I did the oil changes) including transmission fluid and coolant changes spark plugs, belt sand valve adjustments etc. car is driven lightly as a daily commuter for work

Parking brake suddenly engaged while in traffic car would not move. Car had to be towed brake pads were replaced but mechanic stated parking brake had defect that only the dealer can repair.

While attempting to pass a slower vehicle in my 2018 Honda Accord with a 1.5L engine, the suddenly lost power and stalled down to 20 mph while I was alongside the other vehicle. This unexpected power loss put my life and the lives of others at serious life threatening risk. I immediately brought the care to a Honda dealership, where the tech was able to reproduce the issue. The performed a borescope inspection and confirmed that coolant was present inside one of the cylinders, indicating a failed cylinder head gasket. This type of failure should not happen, especially on a vehicle like this. I was the repair would cost $6,500. After researching, I learned that this is a known defect affecting the 1.5L engine and that multiple class action lawsuits have been filed. I also discovered that American Honda is aware of the problem and has instructed dealership service departments to report affected vehicles. In fact, they have even offered gift cards to service advisors who report these cases, but are charging customers for the repairs. That's nonsense. Just do a simple google search and you will discover what I did. During the failure, the check engine light and several other warning lights came on but only the check engine remained on. Since then the car has multiple indicator lights on. Despite multiple attempts to follow-up, the dealership has refused to return my calls. This is a serious life threatening safety concern that deserves immediate investigation. Thank you.

Honda has known for years that the 1.5L engines installed in 2018 or newer Honda Accords have issues with oil dilution causing major catastrophic engine failures, head gasket damage, fluids leaking into the cylinders, and costly repairs to cars with less than 86000 miles on them. Honda Corporation needs to address this concern before someone dies when the cars engine fails on the highway. My vehicles engine failed on a major road when I pushed on the gas peddle and had no power due to these concerns. Dealership stated numerous vehicles are coming in with these concerns right now which begs the question that it is not a one off situation but a failure of Honda Corporation.

I was driving around and all of sudden my car dashboard shows the Supplemental Restraint system problem.
