Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2018 Honda Accord owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2018 Honda Accord. The contact stated while driving approximately 35 MPH, the vehicle began to brake independently. The contact stated that the hill start assist failure, traction control, ACC, brakes, stability control, Collision mitigation, and other unknown warning lights were illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the EZ Pass sensor, the battery, and e-brake switch needed to be replaced. The battery was replaced. The vehicle was repaired. The contact stated that the failure recurred intermittently while driving at various speeds. The vehicle was taken to the dealer three times. The manufacturer had been informed of the failure. The failure mileage was approximately 29,000.
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.
As I was pulling out the garage from the san francisco international airport heading towards the highway to san francisco the miles per hour is 30 entering and then 65 MPH when you get on highway. The dash board indicates the wrong miles for speed it said 100 MPH. It stayed like that for more than 5 mins. I already had a previous situation with this vehicle where the braking systems engaged as I was on highway in 05/13/2018, and almost caused my life and others behind me, there was significant damage from being rear ended and over 18K worth of damage but Honda dealer keep saying nothing was found faulty! I had them turn 'off' all safety modes cause I'm afraid it will happen again but it keeps coming back 'on'. It yanked me several times when no other car is around me. The braking light appeared several times already since I got it back, and it's like they don't believe you. …
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. …
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. …
Evening before problem started it was a heavy rain in nyc. Morning I started the car and was immediately received 4 messages: "lkas: lane keeping assist system problem. See your dealer.". "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. After turning off and start the car again all displayed failures were gone. Waiting for the next heavy rain.
Tl* 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.
Vehicle running, both driving and stationary, dash indicated three warnings: "adaptive cruise control system problem", "collision mitigation braking problem", "road departure mitigation problem". All three systems were nonfunctional. Dealer advised to drive through a car wash before coming in for repair. The car wash appears to have worked, but this is absurd! Every time it rains or car is dirty, the safety features don't work? Didn't see this disclosure when I bought the car or when I paid for these features.
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.
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.
