Has your CMS (collision mitigation system) in your vehicle turned into a nuisance? The technology in CMS systems is designed to prevent accidents, but when it fails, it causes major safety problems. These problems range from false alerts to unexpected braking, with multiple messages often showing up. These types of issues are similar to those that were experienced with the transmission problems with Ford, which also affected vehicle performance and safety.
If you’re experiencing continual issues with the CMS, it may have been crossing your mind that your car could fall into the lemon category. These laws were put in place for protecting consumers from the defective vehicle, including those with malfunctioning safety systems. Knowing your rights as well as the legal criteria that is used in determining fault could be the first step to turn this around. Practical tips for surviving a collision mitigation system problem are discussed in this article.
Understanding Collision Mitigation System Problem
Collision mitigation systems (CMS) are designed to enhance vehicle safety by preventing accidents. However, these systems can encounter several problems. Common issues include false alarms, where the system warns of non-existent obstacles, sudden, unexpected braking, and multiple warning lights remaining illuminated. These malfunctions can not only inconvenience drivers but also create dangerous situations on the road.

Vehicle makes like Honda mostly face common CMS problems. Such failure really impacts the safety and performance of your vehicle. This is exactly why you need to know your rights and how these problems fit into Lemon Law criteria when you are facing such issues.
Legal Requirements for Lemon Law Claims
For your car to qualify as a lemon under California laws, very specific provisions must be met. Normally, the mechanic should be unable to fix your vehicle if it has major flaws that jeopardize safety, value, or use, and after several attempts at repair. Knowing what is the average lemon law settlement would prepare you for if the above needs are met by your vehicle.
Here are some of the criteria for a vehicle to qualify as a lemon in California:
How many repair attempts have been made on the vehicle?
Your vehicle must have undergone multiple repair attempts without success for the same issue. Usually, three to four attempts are considered sufficient.
The time frame within which these repairs took place
The problems must occur within a certain time or mileage limit, often during the first 18 months or 18,000 miles of ownership. If you are in Los Angeles, you may consult our lemon law attorney to get information about specific car make and model.
Substantial impairment
The defect must substantially impair the use, safety or value of the vehicle. Common CMS failures such as unexpected braking or false alarms usually meet the threshold of substantial impairments. A good understanding of these criteria will assist in establishing whether the CMS problem of your car makes it a lemon. It may be either replaced, refunded, or you can get cash compensation for your vehicle if it qualifies for the same under Lemon law.
How to Document CMS Problems
Detailed records of your collision mitigation system (CMS) problems are vital for a successful lemon law claim. Follow these steps to document effectively:
- Keep a log of all your repair attempts, including dates, what was wrong, and what was done to fix it.
- Collect and collate all repair invoices and work orders. Be sure these have very detailed notes on the CMS problems and what was done to repair them.
- Whenever you correspond with the dealer or manufacturer concerning CMS problems, do it in writing. E-mail is best, for it leaves an evidence trail.
- Record your experiences with the CMS, listing dates, times, and descriptions of the problems. Describe how these problems affect your driving.
- If possible, take photographs or videos of the malfunctioning CMS. Such evidence will support your argument.
- Insure tight connection of battery terminals. Loose or corroded battery terminals can cause fluctuations in the electrical current that could cause CMS warnings.
By keeping good records you will be able to amass a lot of evidence if you ever need to make a case under lemon law for the problems with your CMS.
What To Do If Your CMS Fails
If your collision mitigation system (CMS) fails, follow these steps to address the issue and protect your rights:
- Watch out for the error messages on your dashboard telling you if there’s something wrong with the CMS.
- Inspect the brake switch for failure.
- Verify that the brake lights are functioning properly, as faults with the brake switch impact the braking system and brake lights, which can lead to error messages possibly being shown.
- See your car manual for precise diagnostics.
- If this condition exists, refer the vehicle to your dealer for a complete and proper inspection and, if necessary, repair.
Get in contact with the dealer
Take the problem to your dealership immediately. Make sure they note it down and try to repair it.
Seek repairs
Allow the dealer a reasonable number of attempts to repair it. Maintain good documentation of all those visits and what was done.
Notify the manufacturer
If that doesn’t work, write to the manufacturer of the vehicle. That way you have your complaint on record. This implies that you will handle CMS problems in the right way and be assured of getting the compensation or replacement that you deserve.
