Adaptive Cruise Control problems of the 2018 Honda Accord - part 2

Warning lights comes on and the car slows down.

The accelerator is going out when I drive. The car drives slow and pulls back while driving. Thought it was fuel pump, took it in for fuel pump recall, & the car is still doing the same thing, no change. All lights on dashboard are on. The safety of my children & myself has been put at risk quite a few times. While driving the car getting on the freeway ramp, the accelerator went out going up an hill and luckily I was able to put my emergency lights on & able to barely get over to the right side. My car almost stalled. I’ve taken it to the dealer a few times. When I took it to fix fuel pump recall, they said 2 other codes were coming on. I took it in again this past week to check those 2 codes hoping to get it fixed & he said now other codes were coming up. They couldn’t seem to find the problem. The guy said they had been working on it since 9am and it was almost 4 pm when I talked to him. He called me an hour later to say it could possibly be the head gasket but not for sure. My vehicle has been inspected by the Honda dealer. When the problem first happened on the freeway warning lights came on. Warning lights on are: collisions mitigation braking system on, adaptive cruise control problem on, hill start assist problem vehicle may roll on, vehicle stability assist system problem on, electric power steering system problem on, brake hold system problem on, brake system problem performance on, tire pressure system monitor on, emission system problem on.

I have 2018 Honda Accord sport 2. 0 manual transmission. I’m dealing with the abs module malfunction where the abs module board is detective due to the pins being unsoldered due to intense heat in the engine area. To repair the abs module it costs around $1200. But Honda has not made the abs module better. Mechanic states even the new module will not be guaranteed after replacing the module. I need help to get this item recalled. As this issue has been going on for any Honda from 2011-2022 veichels.

Over the past two weeks, I have encountered problems with my car's many lights. These issues have been related to issues with the braking system, collisions, road departure, emission system, acc system, vehicle stability, and electric power system. By disconnecting the battery, the lights have been switched off. My car can only be operated in this manner. ) the automobile would not go faster, and I was stuck in traffic, endangering my safety. There might have been an accident if someone had been speeding. This had happened before, and when I called the Honda store in milledgeville, georgia, to report the problem, they said they were unable to locate a problem because the lights had vanished. Yes, butler Honda in milledgeville reported that they were unable to locate a problem. The mechanic informed me that it was ok to drive even if the car had lights on because they couldn't use the car today. However, a few days later, the lights had vanished once more. It occurred approximately once in July 2023, twice in December 2023, once in March 2024, and once in April 2024. Before the several lights, there was no warning light.

2018 Accord consistently has the warning pop up for the the crash mitigation system and tells me to visit the dealer. Cruise control just stop working while driving. When I turn the car off and back on it resets, and then 10-20 miles goes by and the error pops up again. Incredibly unreliable and unsafe when I’m on the freeway going 70. This has been a constant problem.

Instrument cluster lights up with the following warnings: road departure mitigation,brake system,vehicle stability assist,acc,collision mitigation,emission system problem, electric power steering, hill assist,brake system hold. Obd2 codes are: po301,po301. Dealer diagnosed problem and solution replace fuel injectors. Car with 50,000 miles run fine. Idiot lights are out of control.

Engine stall while driving, and blown engine gasket.

Vehicle stalls upon start on multiple occasions. Vehicle will not start at all on multiple occasions. On approximately February 2024 vehicle sent a warning signal while driving. Warning states vehicle cannot accelerate while driving on the highway, then vehicle slows under traffic speed causing fear of crash while on the highway causing me to pull over and restart vehicle. After restart, vehicle stalled again. Children were present in the vehicle. Called dealer to inform about the issue and was made aware of recall on fuel pump. Dealer does not have parts and will not have parts for recall for months. Called dealers near me periodically over the course of months. All local dealers reported parts will not be available for ongoing months.

Well to start I had to replace my head gasket already last winter at 59k miles and for awhile now I had warning lights on my dash for cmbs system failure and cruise control/steering wheel controls don’t work besides the ones for music. No lane assist, none of those safety features work at all and haven’t for awhile.

I have 2018 Honda Accord which has been recall about 3 weeks my car my car start skipping, when I was driving it so the 12/18/23 all the lights came on and the car started jerking around so I took it to the dealer and they told me found crack in spark plug they replaced the spark plugs adjusted the valve the car started jerking again on 12/25 /23 I took it to the dealer they told me the head is cracked and the spark plug is cracked different cylinder the brake and acc radar light is still on and needs to be replace I send you all the invoices and work needs to be done to the Honda corporation! but they are refusing to do their job and help me this happens to my car because of the the fuel pump issue with this year model I hold you the Honda corporation responsible what happened to my car ! it is on theme to fix and reimburse me for the money that I I already spent and I need my car to be repairs as soon as possible and I need replacement car for me until my car is fixed! but the Honda corporation is saying they’re not able to help me they are trying to play the game with me tell me that car has this problem because it’s has 113000 miles on it but my issue with Honda is that manufacture issues with fuel pump that why my car has this problem thank you nasim akhunzada.

My Honda Accord 2018 with 49,000+ mileage suddenly showed multiple warning lights on the dashboard causing parking break to malfunction; acc, collision assist malfunctions and many other warning lights appeared. I brought it to Honda waldorf maryland and they told me it was definitely the 2 rear calipers as they diagnosed, but this did not solve the problem after replacements. After about 3 days with my vehicle still with them, they told me that it was the module that is malfunctioning; I can no longer refuse them because my car has been there for several days and it's only the Honda that can fix this as the service rep stated and I really need my car. On the other hand, I checked Honda website and called them that there are recalls on the Honda Accord 2018 - 2020 modules. Unfortunately, my VIN is not included even it clearly states that Honda Accord 2018 is included as stated on their website (see attachments).

My Honda Accord 2018 with 49,000+ mileage suddenly showed multiple warning lights on the dashboard. Honda waldorf maryland misdiagnosed that it was definitely the 2 rear calipers, but this did not solve the problem after replacements. After about 3 days, they told me that it was the module that was actually malfunctioning but I can no longer refuse because my car has been there for several days and it's only the Honda that can fix this as the service rep stated. On the other hand, I checked Honda website and called them that there are recalls on the Honda Accord 2018 - 2020 modules. Unfortunately, my VIN is not included even it clearly states that Honda Accord 2018 is included. Please see attachements.

Failure in road monitoring camera prematurely, 70,000 ish miles.

The problem began a month or so ago. I had my car diagnosed at the Honda dealership and it has a fuel injector fuel pump issue. All of the vehicle lights are on tpms engine light brake system light steering light collision mitigation emmission electrical steering hill start assistive cruise control lkas and brake hold light. My car stalls while driving. It sputters when I start it. When I attempt to excelerate the car is not getting gas and the car wont go. I fear for my safety and the safety of others while driving because the car stalls. Can someone please contact me.

All electrical warning lights came on dashboard. This is very frustrating and scary. This needs to be a recall on this vehicle because nothing this serious is normal. I thought my car was falling apart. Honda needs to fix this problem and the owner should not be responsible.

For the last couple of weeks, a bunch of warnings pop up related addaptive cruise control, collision mitigation braking and so on. The car acc would stop working and car would auto brake without hitting brakes. I have checked online and see NHTSA has identified this issue but no action was taken. I am scared for my safety in this vehicle as well as my family. This issue needs to be fixed soon.

Starting in sept 2023, while pulling out of a park in a garage, my car started throwing numerous warning messages in the dashboard regarding emissions, abs, brake system, power steering, etc with the check engine light staying steady. I took it to one Honda dealership who after 'diagnosing' claimed it was the fuel injectors needing to be replaced. The car wasn't jerking or sputtering so I took the car to another mechanic who also didn't believe it was the fuel injectors and felt it was electrical. Took the car to another Honda dealership and they claimed the same thing about injectors. After having a reputable mechanic do software updates that the original or 2nd Honda dealership never checked for (it needed 4 updates, but one of them couldn't be done for lkas). Most of the warnings went away due to the updates but the lkas warning and collision warning remained. So I took the car to safelite (they had replaced my windshield back in July and back then they were able to recalibrate the sensor) but this time (oct 2023) not only were they not able to recalibrate the lkas, they said the front camera was not communicating with the system and this was an electrical problem and I have to go back to the dealership. After reading numerous complaints and similar issues in regards to the lkas, this multiple warnings and the car ghost braking on its own every now and then months before this, I hope you all really look into this and do a recall or find a solution on this car. Now I am forced to go back to the Honda dealership and will have to threaten them to do their job this time and really look at the car and not just tell me it is needing fuel injectors replaced. The car drives, no jerking, no sputtering, but not having a front camera talking to the system and now the tpms system keeps saying I have low tire pressure and won't let me calibrate even though my tires are at the optimal 32 level stated in the manual, I fear more issues are going to pop up soon.

The vehicle keeps stating the brake mitigation, acc, and other various Honda sensor features need to be repaired and to contact a dealer. The vehicle DE-accelerates on its home and doesn’t allow any of the Honda sense features to work. All the components of the dash are triggered at once. Most of the time the vehicle drives fine without the use of the Honda sense features. I have brought this to Honda and they state they don’t see any issues known to cause this problem. Short of the fact they never seem to happen when I bring it to the dealership. Most of the time this goes away on its own but lately the problems are lasting days. I don’t feel safe driving my own vehicle which has been greatly maintained.

Honda Accord 1. 5 turbo, head gasket blown for the second time in 2 years. The problem has been reproduce by dealer and independent service center. The car shakes when you turn on the car, first indication. Then all warning lights show up on dash board. Emission system problem, brake system, vehicle instability, adapative cruise control, road departue.

The contact owns a 2018 Honda Accord. The contact stated while starting the vehicle, the adaptive cruise control (acc), tpms, anti-theft system, braking system, and traction control warning lights illuminated, and the messages "collision mitigation braking system problem. See sealer", "road departure mitigation. See dealer" were displayed. The contact stated that the adaptive cruise control (acc) mode, the econ mode, and sport mode were inoperable. The contact stated that she turned off and restarted the vehicle, and attempted to reset the vehicle herself; however, the failure persisted. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed nor repaired. The failure mileage was approximately 88,697.

After this car was repaired by the body shop, all the automatic systems in the car started flashing and no one could figure out why. It went to four different repair shops over several months, till finally they convinced me to purchase another vehicle when this one was going to be paid off in two months. This problem was well documented by several repair places , and ultimately since it was unrepairable I had to trade it in and got bottom dollar for a non-running car that I owned since the beginning and got screwed.

My acc went out along with my collision mitigation system and no accident just for no reason.

All electrical warning lights came on dashboard. This is very frustrating and scary. This needs to be a recall on this vehicle because nothing this serious is normal. I thought my car was falling apart. Honda needs to fix this problem and the owner should not be responsible.

Acc, breaking system, lane departure, collision warnings all on. Cruise control not working! the cmbs is not functioning properly.

While driving in highway, all dash light slit up like a christmas tree and vehicle lost power. I was not able to go over 30 mph and was in danger of being rear ended on freeway. I was able to pull over to safety and turn vehicle off. Upon restarting the vehicle, I was able to make it back home. This has happened on 3-4 diff occasions. Honda is not accepting responsibility. They continuously refer me to Honda dealer to be ripped off for a diagnostic. There are several forums online complaining about the same issue. My battery and alternator is good. Please help and hold Honda accountable to their negligence in the build of these vehicles.

The vehicle has faults on the dashboard, all the warning lights come on and there are functions that do not work when they are on.

I down loaded my update through the radio. It said complete. I went into the house and the next morning I started it and a bunch of warning lights were on and have stayed on. I can not use some of the buttons on the drivers door, I can not use my key fob unless it is touching the start stop button, I can not open the trunk, the gas cap will not open, and most of all I have lost some power to the interior fuse box. This car is only 5 years old almost to the date and it has had multiple recalls already. I want the bcm reprogrammed and fixed so all this will go away.

Road departure mitigation cruise control collision mitigation emission systems not working when I drive my car it stalled.

I was using the cruise control feature while driving and it gave multiple errors. It happens each time I use the cruise control feature and assisted driving feature. The errors it gives are: 1. Road departure mitigation system problem. See your dealer. 2. Adaptive cruise control system problem. See your dealer. 3. Collision mitigation braking system problem. See your dealer. I have also been driving and it breaks by itself and there is nothing in from of the vehicle. It was an orange flat plate on the road for construction. I have taken the vehicle to the dealer but they say it’s all normal.

All dashboard warning lights come on. (brakes, vsc, steering, etc) message says take to dealer. After doing a google search, it appears to be a common issue for Honda Accords for 2018 and newer. They will come on and either stay on for days/weeks at a time and then just go off on their own. Dealer has no solution.

Well I've had the car for about a year now and it has been good for the first few months, then I ran into a snag. All the orange warning lights for my safety features popped up and the vehicle was applying the brakes on its own. So I took it to the dealership and they told me it was a taillight, so I spent 500 bucks on one. Well after a month it's started to do it again this time worse, and it got so bad. I've had to pull over to the side of the road and restart the car because it kept braking while on the highway. Fast forward months down today and it's still doing it except much much worse. I tried to trade it in because I don't feel safe with vehicle anymore. But where I owe so much on it they won't let me get something else, so I'm stuck with it. I've made an appointment to see if they could check it out but at this point I just want it paid off and I want something else.

While driving in stop and go traffic on the highway with the adaptive cruse control system enabled the system will suddenly stop working. A message appears on the dashboard information panel "braking mitigation system error/failure: bring to dealer". This has occurred twice in 2022, and once or twice in 2021. When the car is turned off, then restarted, the system appears to reset itself. I brought the car to the dealership, they ran a "diagnostic" and told me they detected software errors and needed to do a "flash" reset, and that it was not covered under warranty. I contacted the Honda corporation and provided my service records, and details of the incident. They were lacking in enthusiasm to investigate the issue, as they were more interested in informing me that the vehicle was over the 36,000 mile warranty period. There was no collision, but that does mean there won't be in the if there is a software malfunction with the braking mitigation system. I feel the Honda corporation is not taking this safety issue seriously.

Engine misfire causing limp mode. Dealer says head gasket blown. When misfire happens, all driver safety system warnings display. Car goes into limp mode which is dangerous if on high speed road. First appeared oct-10-2022 with 59k miles on vehicle. Second appeared Nov-29-2022 with 60,300 miles on vehicle. Honda refuses to cover expense of replaceing head gasket and determining root cause.

I have a 2018 Honda Accord 2. 0. Twice it left me stranded on the side of the road due to a failing fuel pump. The first time it kicked back on after an hour and all the lights turned off so they said a diagnostic cannot be performed. The second time I was driving in the middle of the road and the engine cut off and would not start, luckily I had some space to pull over but I was still in traffic and I called a tow truck. It took 6 1/2 hours to finally get it to the Honda dealership and they told me my fuel pump had failed and there is a recall for 2018 2. 0s but not my specific VIN so I have to cover the cost. It’s $1055 plus taxes even though there’s an active recall for other 2018 2. 0‘s but not my exact vehicle. The part is on back order and can take up to a month they are providing no service car and no help on the recall.

Extended highway driving(500+miles). Collision mitigation problem continues to show as alert in dash. Does seem to reset when vehicle turned off and back on but this is not a new problem and a major reason for purchase.
