A 2022 Honda CR-V Radar owner recently revealed that the manufacturer asked for $4,300 to replace the ride; the owner felt that it was cheaper to simply replace their lemon with a better model. Honda cars are quite reliable; this manufacturer was founded in Tokyo back in 1946, producing 4 million models a year. These cars remain among the most reliable vehicles on the road, yet advanced safety systems can still fail. Issues like those outlined in collision mitigation system problem reports show how a safety feature can quickly turn into a costly and dangerous defect when it malfunctions repeatedly.
The collision mitigation system (CMS) is one of these astonishing innovations that can detect potential collisions and intervene on its own to reduce crash risk. The CMS is supposed to be a lifesaver, but it can sometimes have problems that make it dangerous. We’ll discuss the worst collision mitigation system problem areas here to help you understand this issue.
News websites revealed that around 1.7 million Honda vehicles were investigated in 2022 for braking-related problems. Honda vehicles are not aliens to safety-related problems. So, what is this collision mitigation system problem everyone’s talking about? A CMS is basically an advanced safety tool embedded in modern vehicles. It monitors your car’s surroundings and uses its sensors to detect collision possibilities. Its components are:
The CMS has radar sensors that emit radio waves. These waves bounce off different objects in your surrounding area and then return to these sensors. That’s how your CMS calculates how far that object is and where it lies relative to your vehicle. Cameras capture visual data that helps your car’s sensors identify the nature of these objects. Are they pedestrians, other cars, cyclists, or something else?
Some systems are so enhanced that they detect these objects via “lidar,” which means light detection and ranging. They may even use ultrasonic sensors that are great in bad weather conditions or tight parking scenarios. This sensor data is fed into the CMS to build real-time situational awareness of your driving environment.
The collision mitigation AI uses sophisticated, well-trained algorithms on enormous datasets of driving conditions & scenarios. It keeps analyzing sensor inputs to predict whether a crash is imminent or not. This AI also calculates the relative speed & trajectory of detected objects.
For example, if a vehicle ahead suddenly brakes or a pedestrian steps into the road, AI will determine the chances of impact. That’s how the CMS responds proactively, not actively!
When the CMS computes a risk of collision, it provides timely alerts to the driver via multiple modes to make sure that you are aware of what’s happening and can react right away. But these alerts are cautionary; you may hear beeps or get warning tones. Visual signals include flashing dashboard icons or tactile feedback (e.g., vibrating steering wheel). These different multimodal alerts capture your attention right away, so you may take evasive action.
Let’s suppose you were so distracted that you ignored the beeps, or you heard the beeps but couldn’t respond in time. The CMS will then initiate automatic emergency braking (AEB). This intervention applies the vehicle’s brakes to reduce speed or bring your four-wheeler to a complete halt (in extreme cases). The AEB lowers the risk of crashing into another car. This function saves people’s lives when people don’t have time to respond to potential accidents.
Many CMS units also work well with other driver-assistance technologies. For instance, we have the adaptive cruise control (ACC); its job is to maintain safe following distances from other vehicles. Lane keeping assist keeps your car in its lane. Then we have the traffic sign recognition tech (its purpose is also self-explanatory). This integration makes your vehicle even safer, working like a comprehensive suite of roadside automotive protection.
Data shows that Honda recalled almost 300k vehicles over engine failure risk this year. So, you should be careful about the vehicles you’re getting these days. When we’re discussing a collision mitigation system problem, some folks argue that collision avoidance and mitigation are the same thing. This table mentions the key differences between these two:
| Collision Avoidance | Collision Mitigation | |
| Purpose | Prevents accidents from taking place | Reduces the severity of a crash if it’s unavoidable |
| Action | Alerts the driver early and/or assists in steering away | Applies partial or full braking on its own |
| Components | Warning systems (audible, visual), steering assist | Automatic emergency braking, partial braking |
| Driver Involvement | High (the driver must respond to alerts) | Low (the car will intervene if the driver doesn’t respond) |
| Examples | Lane departure warning, blind spot detection | Automatic emergency braking, collision braking |
| Goal | Accident prevention | Crash impact reduction |
| Tech Focus | Early hazard detection and driver alert | Automatic braking and speed reduction |
There have been many advancements in automotive technology these days. But CMS still remains prone to many notable issues that impact driver safety & system reliability. All these problems can easily frustrate vehicle owners. We’ll now discuss six major collision mitigation system problem areas that will help you understand what’s awry with your Honda CMS:
The phantom braking issue made Honda a target of federal investigation quite recently. That is because it’s one of the most common and alarming CMS issues facing Honda owners. It happens when the system detects an obstacle or hazard that isn’t actually there (i.e., when the AI hallucinates). It makes your car brake suddenly and unexpectedly. This false positive can startle some drivers and lead to unsafe situations.
For instance, rear-end collisions might happen if a following driver is not prepared for sudden brakes. Your trust in the safety of your vehicles will decline as well. Phantom braking is often linked to sensor errors and software bugs. Even environmental factors confuse the radar or camera sensors sometimes.
Another pervasive issue is the frequent triggering of collision warnings when there is actually no threat present. So, you can experience consistent alerts or warning lights for hazards that aren’t there. These false warnings lead to a situation called “alert fatigue.” You become less responsive to these alerts over time. In the end, when the CMS gives you an actual warning, your mind has become so accustomed to false flags that you’ll ignore the real thing.
The core of a CMS is its sensor array. It includes radar and cameras that are mounted on the front grille or windshield area. These sensors malfunction due to many reasons, such as physical impacts (minor collisions or road debris strikes) and exposure to dirt/snow/ice. Even sensor misalignment caused by improper repairs or normal wear & tear can lead to this.
Misaligned or dirty sensors deliver inaccurate data to the system’s AI algorithms, causing erratic behavior such as phantom braking, missed collision warnings, or system shutdowns. Effective function requires regular sensor cleaning and professional recalibration post-repair.
Don’t forget that your CMS works with the adaptive cruise control. It will adjust the speed of your Honda to maintain a safe following distance. But ACC failures can ruin everything: so, you may face unexpected disengagement or jerky speed regulation. These failures happen due to CMS sensors or software issues that lead to unpredictable driving behavior (when you’re driving at highway speeds).
CMS can also fail to deliver timely warnings in some cases. In other cases, it fails to even activate emergency braking when needed. Late alerts or the absence of collision warnings can increase the risk of accidents, since you won’t have enough time to react. These CMS failures can happen due to software bugs or a fault in your sensors. Let’s not forget about the environmental interference impeding the responsiveness of your system.
CMS features are bundled with other advanced driver assistance systems like lane keeping assist (LKA). Sensor or system malfunctions affecting CMS can impact these functions as well. For instance, a misaligned sensor can cause incorrect lane corrections and lead to sudden or unintended vehicle movements. These failures degrade the comprehensive safety capabilities of your Honda model and may confuse or endanger you.
Honda’s collision mitigation braking system (CMBS) is part of the Honda Sensing suite. It’s remained at the heart of many class-action lawsuits and safety investigations in the past ten years. Owners have pointed out phantom braking as the key problem facing them. They are sick and tired of the CMS activating brakes when there’s no real threat present. These false activations happen during normal driving conditions.
Imagine you’re driving on clear highways or around curves. Calibration problems or software errors can lead to phantom braking and bring your four-wheeler to a complete stop. The suit argues that Honda’s CMBS misrecognized safe objects as collision risks. The NHTSA has expanded its investigations into Honda cars. It has cited almost 1,300 complaints by Honda Accord and CR-V models involving phantom braking.
Honda isn’t alone here; even Ford’s CMS has experienced similar problems (since a faulty and poorly-trained AI is at fault here). Ford owners have reported delayed/absent warnings of imminent collisions. These collisions compromise their safety on the road. Some models have also exhibited inconsistent activation of automated braking that can result in either late responses or failure to brake altogether when the CMS detects collision-risk obstacles.
These problems stem from sensor misalignment or software bugs in Ford’s driver-assisted modules. Ford’s collision warning malfunction complaints are sometimes associated with abrupt or unintended braking. Just like what Honda owners have reported! The automaker has issued service bulletins and recalls to address some sensor calibration and software update needs. But some drivers have claimed that their brand-new Fords are lemons.
Even the most technologically advanced automobiles aren’t immune here. Many owners of Tesla models have narrated how their self-driving four-wheelers tend to accelerate on their own, leading to lawsuits. Tesla relies on a blend of cameras, radar, and AI to make cars drive on their own. But this very technology makes cars vulnerable to CMS-related problems.
Tesla owners often cite false collision alerts as a key issue facing them. Tesla cars can warn them of hazards that aren’t there or activate emergency braking without a reason. So, these problems happen in complex environments like urban areas and funnels. Bad weather often misdirects Teslas and other self-driving vehicles due to the lack of labeled information.
Owners also report incidents where the system activates unexpectedly and causes abrupt braking that can startle drivers and potentially cause accidents or injuries. Tesla has been working on software updates to mitigate these issues, but complaints persist. They are now drawing regulatory scrutiny and class-action lawsuits.
The root causes of CMS malfunctions are multifaceted, involving hardware issues, software bugs, environmental influences, and manufacturing flaws. Understanding these causes can shed light on why even brand-new vehicles sometimes exhibit critical safety system failures.
As we’ve stated many times before, sensor calibration and alignment problems are some of the main reasons why you see collision mitigation system problem areas. Radars, cameras, lidar, and ultrasonic sensors are very sensitive. They require precise alignment to work the right way. Even minor impacts cause these sensors to lose their calibration. For instance, a minor collision or road debris can set the calibration settings of your CMS off.
Misaligned sensors provide inaccurate data to your CMS. The result? Your CMS becomes unable to correctly interpret distances. It also detects nonexistent obstacles and can’t even recognize actual hazards. A misaligned radar sensor falsely detects objects or leads to the usual phantom braking conundrum. So, that’s something you need to take care of!
CMS relies a lot on complex software algorithms to interpret sensor data and execute proper actions. However, software bugs or outdated firmware may lead to system malfunctions. For example, old software can’t process sensor data properly. It leads to false warnings and/or missed obstacles. Bugs may infiltrate the CMS during system updates and cause erratic system behavior. When this happens, you face unexpected braking or warning alerts.
Weather and environmental conditions also impact the performance of CMS sensors. Heavy rain, snow, fog, or hail can make the CMS detect wrong parameters or fail to properly detect hazards. Dirt, mud, snow, and other things can accumulate on your sensors; these buildups cause false positives or false negatives. Sun glare or reflections off shiny surfaces interfere with camera and lidar sensors. These environmental influences are very unpredictable.
Let’s not forget about hardware faults. These faults include faulty sensors. Even integration issues can be fatal to your collision mitigation system’s performance. When your CMS has sensors that weren’t even manufactured the right way, they will be prone to early wear & tear due to no fault of yours; systematic design flaws can make your entire system work awry.
During manufacturing, inadequate calibration or faulty wiring can lead to persistent issues that may qualify the vehicle as a lemon if unresolved after repairs. Keep in mind that the sheer complexity of integrating multiple sensors and software components makes defect detection and correction challenging but critical for system reliability.
