2024 Honda Civic Driver Assist & ADAS Problems

I originally notified my dealer of concerns with my vehicles behavior while using cruise control and they verified that the systems were 'calibrated and working properly'. On a regular basis, my car will automatically and erroneously engage the vehicles brakes while driving, especially while using the automatic cruise control function. This behavior is far worse at night but has happened to me during the day as well and under all weather conditions. Typically, the gauge cluster will show a motorcycle or car being 'detected' on the screen before or at the same time this happens even though there typically is nothing there. Additionally, this may or may not be related. The entire driver assist system and cruise control are constantly failing to function and often show as 'unavailable' - the cruise control, lane keep, and auto stop features will stop working at random while in use constantly; seemingly heavily influenced by even that slightest adverse conditions - driving in the cold? 'System unavailable'. A rain drop hit the windshield? 'System unavailable'. Road is wet? System unavailable'. While I am able to stay alert and correct these issues as they are constantly arising, they should not be available for use on public roads as they at random cause the vehicle to operate in an unpredictable manner and create a significant hazard for other drivers on the road who may not be paying attention - it's not if someone will collide with the back of the vehicle but rather when and how severe - this vehicle should not be hitting the brakes when there is nothing to stop for and a system like cruise control should not constantly and randomly stop working while in use.

The contact leased a 2024 Honda Civic. The contact stated that while driving at 70 MPH, and making a lane change, the steering wheel overcorrected the change due to the automatic lane corrector and swerved across two lanes inadvertently, and collided with a semitruck and then into a wall. The air bag deployed, and the driver's seat belt independently unlatched. The contact stated that the seat belt unbuckled at some point during the collision. The contact sustained face burns and lacerations, right arm/shoulder, and right side rib injuries. Medical attention was needed for the contact. A police report was filed. The vehicle was towed to a lot where the vehicle was deemed a total loss. The manufacturer was notified of the failure. The failure mileage was 22,083.

Numerous defects in my 2024 Honda Civic Sport. I leased this vehicle in January 2024 for 36 months (with a $4,675 down payment and $284.62 monthly payments). From early in the lease, the car has been plagued with serious problems. Below is a chronological list of the issues my vehicle has experienced: Gearbox replacement – Feb 3, 2025 (12,792 miles): The vehicle’s transmission/gearbox failed catastrophically and was replaced under warranty. Axle boots replacement – Feb 19, 2025 (13,384 miles): Soon after, the front axle boots were found to be defective (leaking) and were replaced. Climate control panel failure (moisture damage) – Mar 6, 2025 (13,892 miles): The climate control and infotainment panel stopped functioning due to moisture intrusion and had to be replaced. Refusal to diagnose vibration issue – June 27, 2025 (18,116 miles): I reported a persistent and concerning vibration during driving (which could indicate an unresolved powertrain or suspension issue), but the dealership refused to perform a diagnostic or address it, returning the car to me without resolution. Steering wheel damage & falsified report – June 30, 2025: During a service visit, dealership personnel damaged the steering wheel and then provided a false report that inaccurately stated the damage was pre-existing, instead of taking responsibility. Ongoing audio system malfunctions – (continuing issue): The car’s audio system suffers from frequent USB/Bluetooth disconnections, which have persisted despite multiple service visits. The car's lane assist is triggered at random during drives almost causing several auto accidents. Every one of these issues is documented through repair orders and correspondence. I have maintained a file with all relevant service records, emails with the dealer (Honda of Van Nuys), and photographic evidence (such as photos of the steering wheel after the damage on June 30, 2025). These docs are available

The contact owns a 2024 Honda Civic. The contact stated while driving 30 MPH, the Forward Collision Avoidance system became inoperable. The contact stated that whenever the vehicle was close to another vehicle, the vehicle inadvertently accelerated, with the Forward Collision Avoidance alert warning light illuminated. The contact had to forcefully depress the brake pedal to stop the vehicle. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 13,000.

Hello. My 2024 civic sport had an automatic brake system that failed to operate correctly. As a result of being blinded by the sun that brake system could have potentially prevented the accident in question. Instead, the system did not deploy and the car ended up totaled with both air bags deployed after just a 20 mph fender bender. If the intended systems worked as they were designed, the accident wouldn’t have happened in the first place.

Every time I get in the car at some point in my drive, all of my safety features kickoff. Basically my ADAS. I can’t even use cruise control. There’s a huge safety issue because I was on a snowy road and my traction control was not on cause my Civic to lose control. Good thing I recovered it and no accident. I can drive 5 miles down the road or 200 miles, but at some point it will kick on. I have looked this up, and thousands of Honda owners are having this issue. I took my car to the dealership and they did a diagnostic on it and cannot tell me what the issue was. The dealer was Prescott Honda in Arizona. THOUSANDS owners are having this issue.

The contact owns a 2024 Honda Civic. The contact stated that while driving at various speeds, the Forward Collision Avoidance system was erroneously activated, causing the vehicle to abruptly stop in the middle of the road. The contact stated that during the failure there were no other vehicles or objects nearby. The vehicle was taken to the local dealer who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 8,000.

Twice lately I was following a vehicle towing a trailer with equipment on it. I noticed that the area on the dash which shows vehicles in front of me did not detect these vehicles or their trailers. I am concerned that automatic emergency braking, adaptive cruise and forward collision detection will not work.

I was driving on an interstate highway in upstate NY, just past dusk, when my 2024 Honda Civic attempted to come to a rapid stop without my input. My car decelerated violently, dropped about 20 mph in speed, then immediately accelerated back to the speed set on my cruise control. I did have the Adaptive Cruise Control and Lane Keep Assist engaged when this happened. Interestingly, there was not another car around me nor coming my way in the opposite lanes and the weather was 72 degrees and overcast. This event scared the hell out of me and I was lucky that no other vehicle was close behind in my lane at the time!

Failure in all advanced driver systems at 7500 miles.

When no other vehicles ahead on straight road, decelerates randomly 15-20 mph. Happened at least 3 times on a 450 mile trip. Occasionally also will brake when car ahead change lanes in a different lane than I was driving.

We were driving to northern Minnesota on the freeway. There were no vehicles in front of mine in either lane. The automatic braking system engaged and the vehicle almost came to a stop on the freeway before it disengaged. Approximately 1 hour later it happened again. If there had been a vehicle behind us in either instance there would have been a serious problem. Today pulling into the garage the same thing happened as I was halfway to parking. I am going to disable the feature.

Vehicle 1 (complaint vehicle) was traveling on interstate highway in moderate traffic in right lane while traveling around a slight curve traveling at 60 mph. Vehicle 2 traveling in left lane merged to right lane with approximately 2 car lanes of spacing in from of vehicle 1 (complaint vehicle). I lifted off accelerate in vehicle 1 (complaint vehicle) to slow down and Honda Sensing Collison Mitigation Braking System abruptly apply very hard braking resulting in vehicle 1(complaint vehicle) nosing driving and straightened the steering on the curve. The braking and steering straightening resulted in vehicle 1 (complaint vehicle) crossing the lane line into the left lane by approximately 2 feet before the vehicle could be recovered and a speed reduction by 15-20 MPH. No vehicles were in left lane next to vehicle 1 (complaint vehicle) at the time of incident or behind vehicle 1 (complaint vehicle) to have resulted in a collusion. If vehicles were either behind or in the lane at the time of the incident the Honda Sensing Collison Mitigation Braking System actions would have directly resulted in a collision from its intervention. Contacted Honda and reported incident and inquired how to disable the system permanently and was told the Honda representative that they would pass along the information to "engineering" and the system can only be disabled for each drive and would turn on each time the ignition cycled. I then inquired if anybody would be reaching out to correct the issue and was informed that nobody would reaching out to me about the issue. I expressed the safety issues and was informed other than notifying engineering nothing would be addressed for me.

While I was turning my vehicle it set off the lane departure feature throwing me into a concentrate decretive section on the road. My blinker was on and the feature shouldn’t have went off knowing I was turning my vehicle through me off the road. I was so shocked I peed myself.
