My 2018 Honda Accord Sport has been experiencing issues with its automatic emergency braking system, specifically the Collision Mitigation Braking System (CMBS). The system has been activaing unexpectedly, causing the car to brake without an apparent reason. I-??ve been trying to keep a list of locations that it has happened and it usually occurs under overpasses when the light changes from light to dark. I-??ve reached out directly to Honda and the dealership and neither took my inquiry seriously.

The collision mitigation braking system is engaging while I-??m driving with no obstructions in front of me. The car slows down completely while I-??m on the highway almost coming to a complete stop. This has happened numerous times since Dec 2024. I took it into Honda and they did absolutely nothing besides charge me over $500 for diagnostic fees and told me to get an oem battery and bring it back to be inspected again.

While driving on the interstate, suddenly got 6 different -??warning-?? messages on the dashboard. Most of them involved the brakes. Emergency brake malfunction, brake hold malfunction, forward collision malfunction, adaptive cruise control malfunction, brake system malfunction (use of brakes may be reduced), and road departure mitigation malfunction.

The car is braking even when there is no obstacle or vehicle ahead. I have not driven at higher speed but I fear that if that happens, it can cause incident and injury.

Cars brake/mdoule automatically engaging. Brake light and brake system light constantly flashing. From what ive read seems to be a known issue that needs to be addressed or made a recall. This is a safety issue and can cause harm to the driver and others.

Randomly, my car will start throwing many warning signs when I crank my car. Then it magically disappears after 2 days. Also I drive my car past 40mph and the engine light came on and then I could no longer accelerate. My car was slowing down while I was on the freeway. I pulled over, turned my car off then back on. Everything is back to normal. Next day, I crank my car, warning signs again and then disappears. I took my car to the auto shop and they could not find any codes. I have videos and pictures. There-??s also a Honda Facebook group with my same model car reporting the same behavior.

While driving on highways, with no one in front of me, vehicle will brake while I have my foot on the gas. Vehicle says brake system malfunction. When I let off the gas and push again, it'll accelerate for a second, then brake again even though my foot is on the accelerator.

The rear brakes are horrible. They wear so quick. This is my 3rd Honda Accord and I-??ve never replaced brakes this much on any Accord I-??ve ever owned. Back tires also wear really fast. The rear brakes squeal really bad and makes squealing noises when I-??m driving. No brakes are being applied but the noise continues. I-??ve had this car for 3 years and I-??ve changed brakes 3 times which is ridiculous.

Multiple times in the state of Oklahoma, driving from Oklahoma to Maryland, and in Maryland Washington DC area, the automatic brakes apply at highway speeds on the interstate whenever there is a shadow in the road. It is extremely frightening. I am having the fuel pump recall Repaired at the Honda dealership today. I told the Honda dealership about this problem and they said they were unaware of it. They said they would reset the calibration on the anti-breaking system. However, upon research, it looks like you are investigating this problem. Please add my car to the list of cars affected. I do not know the exact dates that this happened but it has been. I would say at least 20 to 30 times since 2020 when I bought the vehicle.

During regular driving, the vehicle engine will stall and lose power, with 9 different warning lights coming on and ALL advanced driver assistance systems becoming disabled, and I believe ABS brakes being disabled as well. This is due to cylinder 3 misfires and the problem is intermittent, but the loss of power can come on randomly and is dangerous on highways as you have to pull over due to the sudden loss of engine power, restart the car, and hope the problem temporarily goes away. The L15BE engine used in 10th gen Accord engines is widely known to have a faulty engine block design leading to EARLY head gasket leaks (see links) which results in misfires and I think it is imperative that Honda issue a recall as thus far, they have been ignoring the pleas of the owners. I am planning on replacing the gasket ($4000 personal mechanic. Honda charges closer to $6000) with aftermarket parts ($400 additional) as replacing them with OEM parts would just allow this to occur again. Please contact me for more details. The youtube video goes into succinct detail of the design issue at hand which is mechanical in nature, however it directly effects driver and transportation safety: https://www.youtube.com/watch?v=age8_Mi5sEU&list=PLTM0MsUKWXaQEG8lbsVJ99W1TvHbWiAXR&index=5 There are no shortage of people experiencing this and the problem extends to the entire fleet of vehicles using the L15 engine block including CRVs and Civics. https://www.driveaccord.net/threads/blown-head-gasket-any-recall.559243 https://www.reddit.com/r/accord/comments/1ag0fzm/gen_10_head_gasket_failure_update https://www.reddit.com/r/accord/comments/182zdzh/2018_honda_accord_blown_head_gasket https://www.accordxclub.com/threads/2018-honda-accord-sport-1-5-engine-fail.8781/ https://www.reddit.com/r/accord/comments/zn2srz/2018_15t_touring_with_blown_head_gasket_after_4 https://www.civicx.com/forum/threads/blown-head-gasket.83781/

All warning lights came on (check engine, emissions problem, brake problem, tire pressure monitoring system problem, cruise control problem, brake problem, steering wheel problem, and lane keeping assist problem). In addition, sometimes the vehicle will vibrate or shake when first turned on and at times, when braking, the car will shake or vibrate.

The vehicle is stalling while driving to a point where on the freeway it slows down to 10 miles per hour to all of the sudden have all the emergency lights on that come to a sudden stop. I have called 3 different Honda dealers, they said that they need to check what is wrong with the car first making it clear that there is a fee of $220. My daughter has been driving the vehicle in very unsafe conditions. On Friday [XXX] we were on our way to Oakland from the Ventura County (I was the passenger) and in less than an hour driving the car started stalling to come to a sudden stop on the freeway. I took the vehicle to the Ocean Honda dealership the following week driving forcefully the car at 20-30 miles because we could not afford another trip on the towing truck. The service person drove the car from the parking lot to the front of the service office (less than 50 ft) and the lady said the car was in perfect condition and not one emergency light was on! I shared with them images of all the emergency lights were on in the vehicle and as well as at least 4 codes. We left the car and then they called me to notify that there was an issue with the injectors and that the vehicle was still under warranty for those parts because it is under 70,000 miles. The next day the vehicle was given back to me. I asked about the replacement of the gas pump, and they said because the vehicle is not having any issues it cannot be replaced. That night the car stopped on the freeway, I took it back and now they said it was the spark plugs. I decided to take the vehicle to a different dealership. Now at DCH Honda today the injectors were replaced and the car still stalling and stopping. They recommend replacing the spark plugs ($350 they will charge) and I told them I will take it to my mechanic. They said, "but you know the car is not fixed even if they replace them". I said you are telling me this safety issue is that so what is it? Nobody willing to change the GAS PUMP! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMA

I Lost all system brake system tpms vehicle stability electric power steering hill start adaptive cruise control collision mitigation road departure Emission system problem. Check engine code that keeps popping out is P0301 have changed injectors and coil packs and have done further research on vehicle there are a lot of people stating they are a bad batch of injector and I have looked up to buy the injector and are unavailable. I believe the injector are bad and causing multiple check engine to pop up and further increasing the possibility of a crash or accident.

The contact owns a 2018 Honda Accord. The contact stated while driving at an undisclosed speed, the emissions warning light illuminated. In addition, the steering, the brakes, and the navigation features were all inoperable. The contact stated that a warning light illuminated with instructions to take the vehicle to the dealer for service immediately. Additionally, when the emissions warning light was illuminated, the oil became dirty quicker, and the fuel usage increased. The contact stated that the vehicle had been taken to the dealer several times and was reset. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 12,000.

I have a 2018 honda accord. I have had issues with it breaking and nothing being there. It has cause me to almost get rear ended several times and I find it to be a huge safety hazard. I will be driving down an open road and nothing will be in front of me. My car will randomly slam on the breaks and it scares me terribly. This has happened quite a few times now. At first I thought it was a fluke but it has continued to happen and is becoming a major issue.

had vehicle in for a recall, they informed me that my rear brakes only had 10% wear left, but front brakes had 60%+. That seems very strange because most of the braking is handled by front brakes. Additionally, as I sat in the customer waiting area - different service advisors came into the waiting area to also inform 2 other Honda owners that their rear brakes also need to be replaced. My vehicle is driven mostly highway miles but when I further asked why the rear brakes would wear - they said, that happens sometimes with electronic parking brake cars. Note - I've never used the parking brake, but hearing them tell 2 other customers as I sat for over 5 hours in the waiting room seemed very strange and more an engineering flaw and potential safety issue.
