Purchased my car brand new. Within 1.5 years I've had to have 2 steering racks replaced and another component replaced within the steering column. Currently my lane keeping assist problem is on and I'm waiting to get appt confirmation from the service dept manager. My infotainment center went black and quit working and had to be replaced a little over a year after purchasing the car. The paint began peeling off my front bumper within 6 months of purchasing the car. I'm currently dealing with the Honda I purchased from to try to come to a resolution of this issue since I don't want my brand new car to have a bumper repainted and possibly not match and have it show up on a carfax report. Also have what the dealership calls "fisheyes" under the clear coat of the factory paint. Approx 20-25 spots on my entire car. The dealership said they could "buff" the places but shouldnt have left the factory in that condition. The body shop that Honda sent me too said once they started buffing on the "fisheyes" that they couldn't guarantee that the buffing of the spots would correct the issue or if they would need to repaint which I'm not ok with since it is a brand new car and paint might not even match the rest of the car. Also', I should add that all the maintenance and repairs have been completed at the dealership where I purchased my car brand new.

I was driving on a highway when the engine light came on and the car immediately started slowing down even though I was pressing the gas pedal. It flashed there was a failure of the brake system, collision mitigation braking system, road departure mitigation system, hill start assist system, and adaptive cruise control system. The check battery light also came on. The car decelerated on its own with brakes engaged. I had to choice but to immediately pull over and luckily was able to steer to an off ramp and into a parking lot.

The steering rack has a defect. It has been replaced and the same problem is still ongoing. The gearbox has also been replaced but the problem is ongoing. The car makes loud noise when driving, turning the steering wheel, braking. I do not feel safe driving this car. I have had it for 1 year and it’s already been in service over 20 times. I’ve been having issues with this, 2 weeks after I purchased the vehicle. The lane assist is supposed to keep the steering wheel straight, and it does not, tue car merges to the right.

On 11/11/2024 while at an intersection with a redlight, I was the first car in the "merge to the right" short lane, stopped and waiting on right lane traffic on the road that intersected to clear. When it was safe to go, I moved my foot to the accelerator and nothing happened. I realized my vehicle had lost power / "died;" that all dashboard lights were out. I quickly put my vehicle gear in "Park" position and restarted. It did restart but immediately a red warning light began flashing saying "Brake System Failure" and "Take Vehicle to Dealer." I was terrified as I proceeded in the right lane of traffic since I had vehicles behind me as well as in front of me and I had to cross an intersection with traffic merging from an interstate highway. There was not a safe place to go; all businesses along this stretch had no entry except on their back side. I had to proceed across several major intersections before I could get to a safe place. Meanwhile, warning lights continued and included more than Brake System Failure. One was showing a Warning diagram about changing lanes of traffic which I had to do. Obviously, brakes worked because I was able to stop when needed but I was afraid the brakes would not work which could have been deadly for myself and others. Once I was stopped and in a safe place, I called Honda Roadside Assistance and my car was towed to the nearest Honda dealership. As of this writing (six days from incident), Honda dealership is still investigating; they have not given me a cause or solution. They are providing me with a loaner car. There is no recall on 2024 Honda Hybrid Touring although there are multiple posts online with people saying they had same thing happen with this model vehicle.

I was driving the vehicle with no other vehicles in front of me, yet the vehicle hard braked as if it sensed a collision was about to occur. This happened on 08/23/2024 around 10:05 am.

Purchased new in Feb 2024. On June 26, 2024, at 1,207 miles all safety features became inoperable while driving and all failure lights on dash ignited. I took the car to the dealer, and they said the ECM controlling the ADAS systems failed and needed to be replaced, this required replacement of the Rack and Pinion because they are integrated. I got the car back and immediately noted a difference in handling from the new car I purchased in February, particularly with the lane departure and lane keeping option; the car consistently drifts over the lane lines when the LKAS system is engaged, and sometimes realizes the car is leaving the lane and will automatically self-correct by a hard right or left into the adjacent lanes. I took it back to the dealer and the tech took it for a ride and came back saying the car was trying to kill him. He test drove five other Accords and had the same issue. The tech then said he has a new Honda CRX and his does not have this issue but all Accords he drove did. The car now has 1,500 miles on it and I refuse to drive it because I can't trust the safety features since the rack and pinion was replaced. The dealership submitted an incident report to Honda and we have not heard back from them yet. I have 4 other cars ranging from 1971-2013; I feel safe in them and will drive them until Honda can provide me the safe and reliable car I thought I purchased in February.

2023 and 2024 Hybrid Accord vehicles liberally activate brake lights while cruise control is active under even the slightest level of deceleration creating an appearance of a “brake check” when there is no brake check. A traditional car’s cruise control, for instance when set to 60MPH allows you to depress the accelerator, speed up to 65MPH to pass a vehicle, and then release the accelerator. The car then slows down naturally and begins controlling at 60MPH. The deceleration is gentle and the brakes are not applied and the brake lights do not illuminate. The accord hybrid under the same conditions will apply some level of regeneration to slow the vehicle and also activate the brake light to vehicles behind. While it’s understandable that the brake light would be illuminated if substantial regeneration is being applied, the brake light illuminates under even the slightest deceleration creating an unnecessary hazard. This can occur if the car is slowing down from only 2MPH above the set point. Brake lights illuminate although the amount of regeneration being applied is negligible. It can also happen coming over the crest of a hill on a gentle downslope even with no prior depression of the accelerator. This is a serious deficiency and incorrect behavior. The brake lights should only illuminate under substantial regeneration or application of the brake pedal.
