My 2024 Honda CR-V Hybrid experienced a severe total electrical failure that required a complete battery replacement. This massive electrical surge permanently damaged and corrupted the vehicle's infotainment head unit hardware. Ever since this power surge, the vehicle suffers from continuous, dangerous electronic malfunctions. Specifically, the Apple CarPlay and complete audio system intermittently freeze, crash, and shut down completely while operating the vehicle at highway speeds. This instantly cuts off all live GPS navigation, map access, and critical audible and visual vehicle notifications. Even more dangerously, this hardware corruption has caused multiple false activations of the Collision Mitigation Braking System (CMBS), where the vehicle abruptly triggers sudden automatic emergency braking alerts with no obstacles present, creating an imminent risk of a high-speed rear-end collision. Apple Authorized Service Providers have run full hardware diagnostics on my personal smartphone and issued official certificates proving the device has 100% zero defects. Honda Corporate has also explicitly admitted in writing via official chat and email logs that the CarPlay system defect exists on their vehicle's side, yet they claim it is not covered under warranty. Multiple dealerships have actively engaged in constructive refusal to repair. Technicians continuously deflect the blame to my smartphone on paperwork to avoid opening a formal warranty Repair Order, even after I performed complete factory resets on both the vehicle and the device. Under Corporate orders to meet a Service Manager at a different dealership, I scheduled a manager appointment for 11:15 AM. However, the manager intentionally hid and fled the building to evade the scheduled inspection, leaving a severely defective and structurally unsafe vehicle on public roads.

Driver of the vehicle was traveling about 50 miles per hour, Multiple warning notices appeared on the dashboard ranging from Vehicle Stability Assist System Problem, Collision Mitigation Braking System problem, All Wheel Drive System Problem, Electronic Power Steering Problem, Electric Parking Brake System Problem, Brake System Problem, etc., approximately 16 error messages. The front end wobbled, Brakes were mushy, Steering was difficult as if the power steering ceased working. Was able to safely pull off the road. Vehicle was towed to dealer for diagnosis and repair. Dealer pulled codes from the ODB port and it displayed multiple warnings. See attached list of codes from the Dealer Dealer checked multiple systems but was unable to diagnose the cause. Dealer re-set the codes and sent the car home. This could have been a significant safety issue if the event had occurred under different circumstances. Request investigation into Honda to determine if this issue has occurred elsewhere, determined a root cause, and if the manufacturer needs to issue a recall for all affected vehicles.

I love my 2024 Honda CRV which I purchased in May of 2025. But I need to report this for safety reasons. On September 9, 2025 I was driving south on Sare Road near Davis Road in Bloomington IN at about 30 mph when the Collision Mitigation Braking System (CMBS), activated and stopped the car in an instant. It was a rapid, unintended deceleration. The “Brake” message flashed on the dash. This occurred at approximately 7:30 pm, and there was no other traffic around me. No oncoming traffic, no other cars in front of me and thankfully no one following closely behind. There was no collision - however if another car had been behind me they likely would have rear-ended my vehicle. There were no people or animals in the vicinity to cause the CMBS to activate. And I did not inadvertently touch the brake prior to the incident. I was just driving along and suddenly thrown forward and restrained by my seatbelt. I could smell what seemed to be the brakes or tires. I was confused as to why the vehicle stopped. I turned the engine off and checked for traffic, then started the car and continued driving home without further incident. Within a day or two, I stopped in at my dealership ( Andy Mohr Honda) and reported the incident. Today (9/19/25) I was having a transmission fluid service and mentioned the CMBS issue to the technician and he chanced the Settings for CMBS from “far” to “near” and said that should solve the issue and to let them know if it occurs again. My concern is that if it happens again it could result in an accident and cause damage and injury. Especially if I am on the interstate driving at 60 mph.

The vehicle is a 2024 Honda CR-V EX-L with approximately 13,000 miles, purchased at Gillman Honda in Houston, TX on May 29, 2024. The issue involves the Collision Mitigation Braking System (CMBS) activating without any obstacle present. The first incident occurred in February 2025 at around 11,000 miles while driving on a feeder road at ~25 mph. The vehicle suddenly braked to a complete stop even though the road was clear. There were cars behind me, and although they stopped in time, it created a serious risk of rear-end collision. Had I been traveling at a higher speed and the car braked completely, this could have caused the vehicle to flip or lose control. The second incident occurred on September 4, 2025 at ~13,000 miles while driving on a busy street at approximately 40 mph. The vehicle suddenly braked very hard for no reason, but did not fully stop — instead, it resumed immediately. It felt as if the car “took a screenshot,” braking sharply then continuing. This was especially dangerous since I was traveling at a higher speed, and vehicles behind me could have easily collided with mine. Both incidents put my safety and the safety of other drivers at risk. The vehicle was brought to Gillman Honda on September 16, 2025. The dealer acknowledged the safety concern and kept the car for inspection. On September 19, 2025, the service representative confirmed they had contacted Honda corporate and opened a case because of the seriousness of the issue. The car is still being held at the dealership pending corporate guidance. No warning lights, error messages, or prior alerts appeared before either incident. This appears consistent with a known problem that has been reported by many Honda owners in recent years involving unintended braking by the CMBS system. The defect makes the vehicle unsafe to operate, and at this point we no longer feel safe driving it.

Driver assist systems disable themselves occasionally and seemingly at random. It seems that something is hyperactive or overly sensitive with the system. I have stopped to clean areas where camera is and it doesn't seem to make a difference or helps for a little while and then happens again. Unable to use cruise control for remainder of trip without calling dealership and them telling me to press and hold something to shut off driver assist in order to use cruise control. Another time my front collision warning flashed and disabled my cruise control while I was going down an interstate highway recently at 75 mph. Luckily no one was close behind me. I have no idea what it detected that would have set this off because there was nothing there. Not even a tumbleweed. The weather was somewhat windy and it had rained lightly earlier in the trip but was dry at the time this happened. Another time this past week, the lane departure flashed and did the shimmy with my steering wheel and I was not even outside of a lane. And then when I was on my own road going home and no one was coming I deliberately went outside the center lane and it did nothing. This is getting weird. I don't want to be a statistic. It's getting so I am spooked to drive it on a longer trip! I told the dealership during an oil change today but apparently there isn't much they can do? To me, this is unacceptable and Honda needs to better for it's customers.

I was driving on a country road and shortly following acceleration after a left turn, the cars forward collision warning went off, but in an unusual way. It will generally beep and flash the brake signal a few times if the forward collision warning activates. This time I heard one loud beep, saw a flash of the brake signal, and then the car slammed on the brakes to a complete stop. Luckily, there was no one and no other cars around me as I was on a small road without much traffic. The car is currently at the dealership being evaluated. I have sent a request to the general manager to investigate this situation further than just a basic code run or recreation of the malfunction. I do not feel comfortable driving this car without a clear diagnoses and repair.

On Sunday [XXX] and also other times before this, the vehicle will do a fantom breaking. It will slow down, brake, when no other vehicles are near by. On [XXX], the vehicle braked hard while I was in cruise control and traveling on [XXX] near Baldwin, WI. At this time the adaptive cruise control, forward collision warning and brake system warning lights came on. the vehicle was okay to drive the remainder of the way home. I took the vehicle to the Honda dealer on Wednesday February 26th. They reported that they found Code P2583-49 millimeter wave radar fail. They said that they cleared snow debris off front bumper but there was no snow debris on bumper. It was 40 some degrees. I wanted to make you aware of this system problem because the unexpected braking is very hard and could cause an accident if a driver over responds.

When driving along using the cruise control, the vehicle will suddenly act as it is avoiding a collision. The collision warning will show on the dashboard and the car will suddenly slow down to a stop or near stop until I disengage the cruise control and hit the gas pedal. This has happened multiple times while I was driving along a paved road with no other cars or obstacles visible ahead of me. Fortunately, so far, no vehicle was following me at close range but my car stopping in the middle of the road without warning could easily cause a rear end collision or other severe accident.

Component: Collision Mitigation Braking System (CMBS) My car has less than 2,000 miles on it. I have experienced the situation described below 3 times now. Traffic on a freeway/highway slowed down quickly, and I stepped on the brake pedal to slow down quickly but still gradually. However, the collision auto-braking system activated and my car suddenly halted to a stop with plenty of room (about 1 and a half cars length) ahead of me. In 2 of those situations, I can see the car behind me quickly react by swerving into the shoulder. Rather than improve safety, this feature created a dangerous situation. In 1 of these situations, I released the brake pedal to move forward slightly (without stepping on the accelerator) and then stepped on the brake down slightly to slow down; the automatic braking system jerked the car to a stop once again.
