"road departure mitigation system problem. See your dealer.", "blind spot information system problem. See your dealer.", "auto high beam problem. Manual controls available. See your dealer.". turn signals did not work. Hazard lights did not work. Trunk release did not work. Backup camera did not work. Moved to dealer (25 minutes away). But did not start the service.

The problems with vehicle started three months after purchasing it in November 2018. I have four documented cases with the dealership. As well as 7 videos of the incident taken place while the car is in motion. The tachometer and entire dashboard, including entertainment center, shuts off while driving. This is a big safety issue especially while using the gps. The system reboots itself while the car is in motion. Honda corporate is aware of the issue and had not provided a fix for the issue to date, despite representations that such fixes would be available by fall of last year. I also have voicemail from the service and parts director of the dealership admitting fault and no fixes for the problem. I have additional evidence I can share. For "when did this happen?", I have put the approximate last time this issue arose. The problem is ongoing and has been since I bought the car in November 2018. Please note that my pdf files cannot go below 6mb, so I need to submit that to you some other way when you contact me. Thank you for your time.

Repeatedly at random intervals during hot & cold weather I hear loud buzzing vibration sound coming from area housing high voltage lithium ion battery!!! over the past one year. Always while driving at 46 to 52 mph, now in cold weather is starting at 35 mph. I fear over heating or fire from high voltage lithium ion battery!!! I had the dealer replace a mic located in the cabin and not problem was corrected, 7 different technicians at Honda had hear this noise but they don"T know what it is. This is been happen since the car had 4200 miles now is 28000 and is getting worst. Please if you having this similar issue take the time to report it here so Honda can take it serious this can be a fire hazard.

The vehicle had a sudden loss of function in: 1. road departure mitigation 2. collision mitigation 3. adaptive cruise control 4. braking system the vehicle was in motion at speed of 10-40mph, with air temperature of 28-32 degrees and snowy conditions. Honda has repeatedly refused to investigate numerous, potentially sw/hw - related issues that have been manifesting themselves in other parts of the vehicle. What happened today was a new set of symptoms, but with much higher severity and no obvious precedent. I have already had to disable the lane departure and the collision avoidance systems on this vehicle due to their erratic behavior. However, in this case the messages that have come up (will attache photos) demanded that the vehicle be taken to the dealer and the errors and message did not go away upon multiple restarts of the vehicle. Upon arrival to the dealer, it was indicated to me that Honda is aware of some of the other issues I've been experiencing with the vehicle and still (months hence) does not have a fix, and that Honda has, essentially, been resorting to testing their vehicle on the customers, instead of more rigorous pre-release testing, instead choosing to use the dealers as a quasi-test/R&D department. The multiple safety system failure I experienced today is a pretty clear indication of that. I have filed another complaint with nthsa related to the other issues and would urge you to initiate a recall on all of the Honda Accord (and possibly Odyssey and Pilot as they share some of the sub-systems) for the 2018, 2019 and the coming 2020 models.

Collision mitigation system failed, brake light is on, adaptive cruise control system warning is

- Blaine, MN, USA

Vehicle crash avoidance system erroneously applies brakes when no vehicle is in front of the vehicle and causes near rear end collisions while moving on local or interstate roads. This has been occurring since the vehicle was delivered new.

- Knoxville, TN, USA

The brake system alert is flashing on the dashboard while vehicle in motion and there is no break issue. It appears to be a flawed collision mitigation brake system sensor as this keeps flashing across the dash in big bold letters and wont go off. I just bought this vehicle brand new 5 months ago. When turning car off and back on the message is still there and wont go away.

After being parked in a friends driveway for several hours I proceeded to open my car and drive home. First remote control would not open doors, after several tries it open the driver door only, upon turning ignition on a series of warning indicating the adaptive cruise control system automatically disables itself, all collision mitigation functions stop working, series of warning see pics appear on display to see dealer, all windows and truck will not function, turn signals and brake lights, rear view camera do not function, brake system msg appears on display. Turned off and on car with no success in restoring all functions as on two previous occasions. Drove car for 4 miles in this state felt it was dangerous for us and other drivers. This morning all has restored to normal. Called Honda dealer in el monte ca. Was told they did not know anything about this type of problem, was not able to book service call until middle of next week in researching online found Honda service bulletin 19-051 describing a software update to car modules to fix this problem. I believe that is really should merit a recall as it interferes with the safe driving of the vehicle. A recall will force Honda to inform its service dealers and instruct them on a prompt scheduling of required software upgrade to resolve this software defect affecting drivability of their flagship car.

Vehicle had issues cranking and the display had every error code flashing one after the other. After going to the dealership we were told that it was the fuel pump. It was replaced in July. The exact same issue has happened again in October if the same year and we are being told that it is the fuel pump again.

My 2018 Honda Accord sport crash mitigation system is not working correctly at highway speed with no vehicles around the brakes apply hard at times taking the car from 65 miles an hour down to 40 mph in just a few seconds on one occasion I almost got rear ended by a tractor trailer Honda says there's nothing they can do about

The contact owns a 2018 Honda Accord. The contact stated that the tire pressure monitoring system (TPMS) warning indicator illuminated when the ignition was started. The vehicle was taken to an independent mechanic where the contact was informed that the tires were perfect and the TPMS was reset, but the failure recurred. The vehicle was not taken to a dealer for diagnostic testing or repairs. The manufacturer was made aware of the failure and informed the contact to take the vehicle to a Honda dealer. The failure mileage was 35,000.

Honda's collision mitigation system shuts down, disallowing cruise control and all safety features that are included in the collision mitigation system. Dealer cannot find cause. Turning off the car and restarting it resets it, but when it turns off, there is no clear factor as to why it happened. There is a safety risk if you are using cruise control, as it could fail to brake when the car in front of you slows down. It has happened 4 or 5 times in the past 8 months since I bought it brand new.

All the lights in the dashboard start flashing and the message was take it to the dealer right now. This is a 5th time it happens I took it back to the dealer and they replaced the multiplex controlled unit module

During stop and go traffic, car braked causing the person behind me to rear-end me. This had happened one other time before, luckily the car behind me wasn't following too closely and I was going less than 30mph. A couple weeks after that while going highway speeds and wet road conditions, a warning light came on stating there was a problem with the collision mitigation braking system and to see dealer. Once that warning comes on cruise control also disengages. This warning light has come on one other time, while driving highway speeds with dry road conditions. If the car is restarted the warning resets and all systems are up and functioning again.

Catastrophic failure. Turned vehicle off, noticed alarm did not work. Hours later tried to enter car and noted the following: Trunk will not open, doors except for driver will not open, turn signals do not work, no high beams, all mitigations systems offline, brake system failure, back up camera doesn't work. Thank goodness experienced driver could get it home and/or I was not far from home with vehicle. Said car is less than a year old and has 10K mileage.

- Woodbine, MD, USA

Collision mitigation braking system problem which causes the adapted cruise control to deactivate itself all of a sudden when driving in high or low speed traffic, happens on highway or regular street, all kinds of weather conditions from rain to sunshine. Very scary especially while going on I-95 in high traffic that is all moving very fast. Has happened at least a dozen if not more times and the dealership could not find a resolution. Taking it again next Wednesday 5/15/19.

While driving on the freeway, the vehicle front collision system stopped the car randomly causing a potential hazard. It is doing it intermittently with nothing in front of the vehicle
