Honda Accord Hybrid adaptive cruise problems

Filed Oct 6, 2025 · Acceleration, Electrical · MI

While driving ~70 mph on highway on adaptive cruise control, the car suddenly LOST ALL POWER/ACCELERATION, including POWER STEERING and ALL WARNING LIGHTS FLASHED ON THE DASHBOARD. I recalled some were BREAK SYSTEM, ACC, ABCS, CHECK ENGINE, POWER, TPMS...etc. Essentially any warning light Accord has was flashing. The car slowed with no power steering, I managed to parked on the shoulder and turned on hazard light. This is extremely dangerous as the highway traffic was extremely heavy. After I parked, I pressed the ENGINE START/STOP button thinking I needed to "turn it off" but the car already had lost power at that point anyway. After pressing it a couple times, the car restarted and I drove to the dealer with one error message remaining on the dashboard - "Emission system problem. Power may be reduced. See you dealer." and the CHECK ENGINE light was on.

When traveling on an Interstate Highway in the left lane of a 2-lane highway with the Adaptive Cruise Control turned on. Passing a tractor trailer going slower in the right lane, the car will apply the brakes unexpectedly. The dash will briefly show a "ghost" truck crossing into the left lane. The unexpected braking causes any vehicle behind the Accord to brake. Putting those vehicles and any behind them at risk. Smart Honda of Des Moines looked at the car on Sept. 22, 2025 reported no error codes and nothing could be done. If the Accord hugs the far left shoulder, no "ghost" breaking occurs. If the Adaptive Cruise Control is turn off and regular Cruise Control is turned on, no "ghost" braking occurs.

The car was in cruise control going 73mph on the freeway. I was passing a semi on the left hand side. When I was parallel to the semi, the car brakes hard and a big "BRAKE" light came on the cluster. There were no cars in front of me and luckily no one behind me. If there was a car behind me there would have been a collision. It was a clear day and again the road was clear. It took me from 70 to about 40 mph until I hit the accelerator to get back to speed. The CMBS is faulty and I will take it in to a dealer asap.

All of sudden, no incident, no accident, a lot of things were disabled such as Adaptive Cruise Control , Forward Collision Warning , Lane Departure Warning and more while I was out of town (long range highway travel). When I went to Honda dealership, they blamed a few things and fixed them (expensive), then they said that the front camera needed a calibration. It was expensive. After that aiming correction, everything works fine. The camera was NOT broken. It just needed recalibration, and it costed about a thousand dollars. I would say it was caused by the poor design, which is Honda's fault. I googled this issue and found a lot of Honda owners had same issued and charged 1K ~2K for it. I will report it separately, but my Honda Odyssey has the exactly same issue now. I have 2 Honda cars, and both of them have the same issue. I strongly suggest that Honda should recall their front camera and they should reimburse the expense we already paid for it.

Since the first winter after I purchased my vehicle in 2021, typically when cold, but not always, I lose all the Honda Sensing (Advanced Driver Assist Features). The dashboard lights up with the following warnings . - Collision Mitigation Braking System Problem. See Dealer - Road Departure Mitigation System Problem. See Dealer - Auto High Beam Problem. See Dealer - Adaptive Cruise Control System Problem. See Dealer - Lane Keep Assist System Problem. See Dealer This failure of these safety systems can last anywhere from 5-60 minutes. Sometimes if you shut the vehicle off and turn it back on again, the warning will go away. On multiple cold mornings (below ~45°F), my 2021 Accord Hybrid displays a cascade of safety system failure warnings upon startup. The dash shows errors for the collision mitigation braking, lane keeping assist, adaptive cruise control, road departure mitigation, and more—all at once. When these systems are disabled, it severely compromises safety. This issue happens repeatedly in colder weather. The dealer has personally witnessed the issue in their service bay and acknowledged it's a known problem but had no fix, advising me to turn the car off and on again. This recurring failure of critical safety systems in cold conditions puts me, my passengers, and other road users at risk.

Vehicle Identification Number (VIN): [XXX] Vehicle Mileage: 29,200 miles Involved Honda Dealership: McGrath Honda, St. Charles, IL Details of Your Inquiry: I am seeking assistance regarding an ongoing issue with my 2023 Honda Accord Sport Hybrid. The first time I noticed this issue was in the summer of 2024, when I experienced a similar set of alerts while driving in a parking lot. At the time, I didn't think much of it, as the vehicle seemed to return to normal shortly afterward. However, on [XXX], the problem occurred again, but this time it was more serious.

Additionally, my Honda app sent a warning stating, “Brake system problem, drive with caution.” During this time, the vehicle experienced a significant loss of power, with no braking or acceleration available. I was unable to use the brake pedal or accelerate, which caused immediate safety concerns. Luckily, I was in a subdivision and not on a busier road like Weber Rd. or I-55, as this could have resulted in a dangerous accident. I was able to coast the vehicle to a stop at the side of the road, where I waited for a few minutes. I then cycled the vehicle off, waited a few more minutes, and turned it back on. The vehicle started, and I was able to drive back home. A video was recorded showing the alerts on the dashboard. I brought my vehicle to McGrath Honda for diagnostics on March 28, 2025. The dealership found multiple lost communication codes from various subsystems, but they were unable to replicate the issue.

It keeps happening every day
