2018 HONDA ACCORD Forward Collision Avoidance Adaptive Cruise Control Problems

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...

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...

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.

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....

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.

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.

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.

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.

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.

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

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

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.

The vehicle's safety system (not sure if it's the camera mounted behind the windshield or something else) will periodically interpret a road speed sign as showing 100mph speed limit. This has happened before and will have happened again (I am filing this complaint after some time has passed). As with a number of other issue with the 2018+ Honda models, Honda's response has been "take it to the dealer" while the dealer's mechanic drives the car for an hour, does not see the issue and then claims that nothing is wrong with the vehicle. A picture is attached.

The contact owns a 2018 Honda Accord. The contact stated while driving 60 MPH with the cruise control activated, the vehicle abruptly stopped with unknown warning lights illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 45,000. The contact stated that at the time of the incident, the automatic braking system engaged by itself most likely due to the fact that a car was really close to the vehicle and possibly sensed danger.

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.

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.

All of my safety features in my car when it comes to driving down the road have completely failed. Adaptive cruise control lane assist brake system errors. The car just stops in the middle of the road. And it will pull the car the car to the left or right thinking that there’s something in the road and there’s not it’s very dangerous.

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...

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...

One day all the car warning lights came on. After I backed out of the driveway, I placed the car in drive and tried to accelerate. When I stepped on the gas pedal the car barely accelerated. It barely moved. I turned of the engine and turned it back on again and the car was ok again, but this keeps happening from time to time. I've had the car checked a few times, but mechanics weren't sure what's wrong with the car. They keep getting a misfire code on number one, but after checking the spark plugs they said nothing is wrong with the spark plugs.

The sensor is located under the license plate, and because of it being so low, anything that hits it on the road, such as a rock or insects, the sensor gets triggered. There’s no protective cap on it. And every single light turns on the dash. Such as the collision, lane departure, brake system and cruise control.

While driving using ACC, the warning message “Crash mitigation not working” comes on out of nowhere and the cruise control stops working. This has happened multiple times. Also, About a month ago, my whole left side of the dash completely stopped working. CAM DTC are the error codes and cruise control and necessary functions just stopped working all together. It feels very unsafe and unreliable.

I have had this vehicle since June 2018 and I have not had any issues until the last month or so. The first incident happened while driving to work and it was raining, when I turned into the parking lot a number of warnings started going off : Electric Parking Brake System Problem, Brake System Problem, Brake Hold System Problem, Electric Power Steering System Problem, Adaptive Cruise Control System Problem. Parked my car, went in my office and called the dealership. They told me it was most likely because of the rain and that the issue should resolve on it's own. By lunch time it had stopped raining, went to get lunch and the warnings were gone, but now when accelerating I would lose power. So I go the the dealership, they check to see what the issue is and they can't find anything. Told me to come back if...

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....

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

I Honda Accord recently has been displaying up to 17 error messages out of the blue. It doesn’t matter if I’m going 30 mph or 80 mph. It happens randomly and there is a power loss associated with it. It is happened to me on the highway and was extremely scary. I have disconnected the battery and the lights will go off for a little bit but randomly Sometimes the same day sometimes a day after all of the lights will come back on and all of the safety feature shut off. i’ve spoke with Honda and they have no known understanding of this happening but there are many many forums of this happening between multiple models of their vehicles around the 2018 range.

Driving at 70 mph on interstate 74 in cruise control the vehicle automatically braked on its own nearly causing a rear end collision by the semi following. Vehicle then proceeded to de-rate down to 40 mph and would not accelerate beyond this causing us to drive down the highway with our hazards on over an hour home. Additionally, after making it home every warning lights for adaptive cruise control, collision mitigation, power steering assist, lane keep assist, etc. continue to come on and off. Vehicle was just at the local Honda dealership where they did a recalibration, to which I just picked up and within 10 miles of driving the vehicle every warning light is back in and vehicle de-rated again. Vehicle is very unsafe to drive and at this point a danger to myself, family and others on the road.

The car’s Collision Mitigation system stops working for no reason, causing me to completely lose my cruise control until I can turn off the car and restart it. This has happened in stop-and-go traffic on the Interstate while the car is under the control of the adaptive cruise control as well as while driving down the road with absolutely no other cars around me. Suddenly the system cuts off and the Collision Mitigation Warning message comes on. The Honda dealership has no response to this. I have had the car since September 2021, and this occurs approximately 3 times per month.

Two times while driving on the highway at 75-80 mph with CMBS system on and utilizing ACC. Out of nowhere, vehicle drops speed, ACC OFF notice comes on and an alert stating Collision Mitigation Braking System Problem. See dealer pops up. . At this point, I have to quickly react to increase speed on gas pedal and avoid someone hitting me from behind. I am not able to re-engage the ACC the remainder of the travel. After turning off the vehicle, the CMBS resets and ACC is available again. This is not possible to do while driving on a highway. The second time it happened, I was changing lanes into the passing lane on left and I seriously could have been hit due to my speed deceleration. I took the vehicle straight to the dealer and the guy checking me in said they get a lot of those system errors....

2018 Honda Accord 1.5Turbo LX - Fuel Injector Failure at 58,600 - diagnosed at Honda Superstore of Lisle, IL. As a result car has low power, all safety features are deactivated, and emission system is malfunctioning. Submitting this issue as HONDA has had several other models with early fuel injector failure which it has recalled in the past. Please contact me if a fuel injector recall is issued for my car.

The adaptive cruise and emergency braking systems. Driving on the highway the car suddenly brakes as if a car is right in front of you. There is no car in front. The dealer has not been able to confirm as this happens so at random. There was no warning that the system would suddenly brake. This has happened 3-4 times in the past year

Supplemental Restraint System failure will pop up at random times maybe every other drive, then that code goes away. Just recently the ACC and Brake System flashes "Problem see dealer" as well as the head unit/display turning off and then back on intermittently. Front interior lights will turn on then turn off, sometimes immediately, and this has all been in the last year they've compiled. Closer to when I got my car a couple of years ago, the cruise control would just turn off and the automatic braking would start to slow the vehicle down. I attribute this to the "emergency braking" feature that would stop me with nothing in front of me, so it has been disabled ever since. Unfortunately my car doesn't fall under the VIN registry for the software recall, and from the looks of the other complaints this seems to be common problem with this car....

While using Adaptive Cruise Control the Collision Mitigation Braking System turns off with no rhyme or reason. This happens often ... 5 to 10 times per month depending upon how many miles I use the car that month. The speed of the car doesn't matter. When the CMBS turns off, the ACC also does not function. The only way to reset is to restart the car. This has happened ever since I purchased the car (new in 2018) but happens more often as time passes. I've reported this to the dealer twice. The first time I was told that the camera lens are probably dirty. (I've thoroughly cleaned the lens to no avail.) The second time the dealer updated the software. That did not solve the problem. The car has not been inspected by anyone other than the dealer. Warning lamps and messages appear when the CMBS goes out.

I was traveling about 45 mph and all of a sudden my adaptive brake system and predictive cruse control lights came on.

All warning lights displayed

WHEN VEHICLE IS ON, SAFETY FEATURES LIKE LANE KEEP ASSIST, ADAPTIVE CRUISE CONTROL, BLIND SPOT INDICATORS, TRACTION CONTROL, DOOR LOCKING, HANDS FREE PHONE CALL ANSWERING AND HANGING UP BUTTONS ON STEERING WHEEL ARE ALL NOT WORKING. MY INFORMATION SCEEN IS LOCKED AND CANNOT BE CHANGED.

THE FUEL PUMPS, MADE BY SUPPLIER DENSO, WERE "EXPOSED TO PRODUCTION SOLVENT DRYING FOR LONGER PERIODS OF TIME" DURING MANUFACTURING, ACCORDING TO THE NHTSA RECALL REPORT, WHICH COULD CAUSE SURFACE CRACKING AND EXCESSIVE FUEL ABSORPTION AND EVENTUALLY CAUSE THE IMPELLER TO BECOME DEFORMED AND FAIL. THE FUEL PUMPS ON VEHICLES PRODUCED OUTSIDE LIMITED DATES GIVEN ON THE REPORT DO NOT HAVE THE PROBLEM. THIS RECALL DID NOT INCLUDE THE 2018 HONDA ACCORD MODELS EVEN THOUGH THEY ARE HAVING THE EXACT SAME ISSUES. MY CAR IS STALLING THE EMISSIONS WARNING LIGHT IS ON ALONG WITH THE ADAPTIVE CRUISE CONTROL, LANE DEPARTURE, AND THE COLLISION MITIGATION. I FEEL THIS SHOULD BE INCLUDED IN THE RECALL THE PUT IN PLACE LAST YEAR BEING THAT IS IS THE SAME ISSUES. MY VEHICLE WOULD STALL IN A PARKING SPOT AT MY HOME WHEN I'M FIRST STARTING IT. IT WOULD FLASH A WARNING LIKE A CAR...

I2 WEEKS AGO I HAD MY CAR'S COMPUTER SYSTEM UPDATED AS PER THE RECALL NOTICE. EVERYTHING WAS FINE THEN 2 DAYS AGO I NOTICED ON THE HEADS UP DISPLAY "CRUISE) WHICH HAD NEVER BEEN THERE BEFORE. I SET THE SPEED AT 65 ON THE FREEWAY AND IT HELD THE SPEED FINE, HOWEVER, AS I APPROACHED ANOTHER VEHICLE FROM BEHIND IT DID NOT SLOW DOWN TO MATCH THE SPEED OF THE OTHER CAR. I HAD TO BRAKE TO AVOID HITTING IT. I TRIED USING THE INTERVAL BUTTON TO SET THE DISTANCE FROM THE OTHER VEHICLE BUT IT DID NOT WORK. I TOOK THE CAR TO THE DEALER THIS MORNING 3/23/2021 AND AFTER 90 MINUTES THEY CALLED ME OUT TO LET ME KNOW WHAT HAPPENED. APPARENTLY, IF YOU HOLD THE INTERVAL BUTTON DOWN FOR 2-5 SECONDS IT DISENGAGES THE ADAPTIVE CRUISE CONTROL AND THE CAR IS REVERTED TO AN OLDER SYSTEM THAT...

PROBLEMS WITH THE FRONT WINDOWS HAVING ISSUES WITH WINDING UP OR DOWN AND EVEN MOVING OUT OF CHANEL. PROBLEMS WITH THE ACCS,LKS DUE TO MALFUNCTIONING CAMERA WHICH I HAD TO REPLACE HOWEVER THE DEALER IN JAMAICA WILL NOT REPROGRAMME

DRIVING ON I-65 AT 70MPH (MY CRUISE WAS SET ALONG WITH ACC AND LKAS). SYSTEM WORKED WITH NO ISSUES FOR ~200 MILES. WHEN THIS HAPPENED, THE CAR IN FRONT OF ME SLOWED DOWN, AND MY CAR STARTED SLOWING DOWN AS WELL. OUT OF THE BLUE, AS I GOT CLOSER, I GOT THIS ERROR IN MY DASH, COLLISION MITIGATION BRAKING SYSTEM PROBLEM SEE YOUR DEALER. IT TOOK A SECOND FOR ME TO REALIZE THAT MY CAR WAS NO LONGER SLOWING DOWN. FORTUNATELY I STILL HAD ENOUGH DISTANCE TO PRESS ON MY BRAKES BEFORE HITTING THE BACK OF THE CAR IN FRONT OF ME.

WHEN STARTING MY CAR, I AM RECEIVING SEVERAL WARNING EVEN AFTER TAKING MY CAR TO THE DEALER. ALL ISSUES WERE CLEARED BUT NOW ONLY 4 DAYS LATER, THE SAME WARNINGS FROM THE SAFETY SYSTEM IS SHOWING.

JULY 2020, ADAPTIVE CRUISE CONTROL (ACC) SYSTEM DE-ACTIVE WHILE I WAS DRIVING AT APPROX 65MPH.RECEIVED DASH BOARD MESSAGE 'COLLISION MITIGATION BRAKING SYSTEM PROBLEM. SEE YOUR DEALER' . WARNING WENT AWAY AFTER RESTARTING VEHICLE.DEALERSHIP COULD NOT REPLICATE WARNING. NOV 2020 ACC SYSTEM AGAIN FAILED, THREE TIMES, SIMILAR CIRCUMSTANCES, HIGHWAY 65-70 MPH, RESTARTING AGAIN CLEARED WARNING. WHEN SYSTEM FAILS THE CRUISE CONTROL ELEMENT TURNS OF, AND CANNOT BE REACTIVATED. ALSO, CAR SLOWS DOWN QUICKLY, BECAUSE SET SPEED IS NOT MAINTAINED.( POTENTIAL REAR END COLLISION SITUATION) CAR WAS PURCHASED NEW IN NOV 2018, NOT PROBLEM DETECTED UNTIL EARLY JULY 2020. PROBLEM HAS NOT BEEN RESOLVED AS OF JAN 2021.

I WAS FOLLOWING MY WIFE'S CAR ON THE EXPRESSWAY. HER SPEED WAS 55 MPH. I HAD THE ADAPTIVE CRUISE CONTROL (ACC) ON MY VEHICLE SET FOR 70 MPH, SO NATURALLY I WAS ONLY 'PACING' HER AT HER SLOWER SPEED, ABOUT FOUR CAR-LENGTHS BACK. SUDDENLY, MY CAR ACCELERATED RAPIDLY TOWARD MY WIFE'S CAR IN FRONT OF ME. I HAD TO HIT THE BRAKES TO AVOID A COLLISION. AT THAT MOMENT, A WARNING APPEARED ON THE INSTRUMENT PANEL STATING THAT RADAR OBSTRUCTED. BUT EVEN THEN, I WAS ABLE TO RECREATE THE SAME SCENARIO FOUR MORE TIMES BEFORE TURNING OFF ACC FOR THE REST OF THE TRIP. I ALSO NOTICED THAT WHILE THE CAR WAS SURGING FORWARD, THE INSTRUMENT PANEL INDICATED THAT THERE WAS NO CAR IN FRONT OF ME, EVEN THOUGH THERE CLEARLY WAS. IT WAS ALMOST AS IF MY CAR 'COULDN'T SEE' AND DECIDED TO ACCELERATE ANYWAY. THE SYSTEM SHOULD HAVE...

ALL LIGHTS IN MY DASH CAME ON, BRAKE, ENGINE, STEERING, COLLISION, ACCELERATION. I TOOK IT IN TO PRIORITY HONDA AND WAS TOLD IT WAS CRACKED SPARK PLUGS AND IT WAS FIXED. I PAID $260. SIX DAYS LATER SAME THING. SAME DEALERSHIP LOOKED AT IT. SAID IT WAS FIX, SENT ME ON MY WAY, BUT TOLD ME THEY WOULD REPLACE SPARK PLUG COVER. SAME ISSUE HAPPENED AGAIN. NOW BACK IN THE SHOP FOR A 4TH TIME. WAS TOLD I HAD BAD FUEL INJECTORS. COST $1700, BUT I WOULD HAVE TO PAY $200 DEDUCTIBLE. PROBABLY IS MY CAR WAS BRAND NEW WHEN PURCHASED AND I'M UNDER 5YR, 60,000 MILE WARRANTY. SO WHY AM I PAYING ANYTHING IF IT IS A POWERTRAIN FAILURE AND I'M UNDER WARRANTY. PLEASE HELP. THESE INCIDENTS HAPPEN AS SOON AS I STARTED MY CAR, AND I TOOK IT STRAIGHT TO THE DEALERSHIP WHEN IT DID. THE LAST INCIDENT...

WHEN DRIVING APPROXIMATELY 50 MPH ON A CITY STREET USING ADAPTIVE CRUISE CONTROL, MY ADAPTIVE CRUISE CONTROL TURNED OFF SUDDENLY. THERE ARE NO OBSTRUCTIONS TO MY HONDA SENSORS NOR WERE THERE ANY INCLEMENT WEATHER CONDITIONS.
