Adaptive Cruise Control problems of the 2024 Honda Civic

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 adaptive cruise control is the safety issue. It creates danger for both me and for others. Traveling at speeds approximately 65-70 mph the car suddenly brakes very hard. Causes me and my passengers to be jolted extremely hard. Its happened 3 times, I was fortunate enough to not have anybody traveling behind me. If a car was to be traveling behind me at a safe distance the sudden braking would cause them to rear end me. I can only imagine how horrible the injuries could be. The problem has not been reproduced or confirmed by dealership. I have an appt. Scheduled March 4. 2025 at the local Honda dealership. There was no warning lamps that came on. There was no messages also no symptoms prior to these incident. Happens for unknown reason. This issue has occurred on 3 separate occasions. The most recent one was on Feb. 17, 2025.

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.

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!.

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.

I was driving on the interstate had car on cruise control set at 70mph it began to slow to 60mph because of a vehicle in front of me so I moved to the left lane to go around and the vehicle just speed up (g5 force) on its own very quickly and reached speeds up to 80mph and would have kept accelerating past 80mph had I not disengaged the cruise control instead of braking. The second issue we have found was the steering became uncontrollable. It feels like the steering wheel gets stuck and hard to control to stay in your lane. You are not relaxed to drive this vehicle. Your body tenses up just to control the steering. We took it to the dealer for the steering recall but I don't think this is the issue. It is something more serious. We refused to drive our vehicle until it is repaired. A loner vehicle was given to us as the parts for the recall will not be in until April 2024.
