Can I Return the Car If the New Car's Sensor Is Broken?

New car sensor is broken can return the car. According to the three-guarantee policy, repair first, if the same problem cannot be fixed after multiple repairs, then replace the engine assembly, and if it still doesn't work, you can exchange the car or return it. Of course, if you return the car, you need to pay some depreciation fees. Function: A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording, and control. Features: The features of sensors include: miniaturization, digitization, intelligence, multifunctionality, systematization, and networking. It is the primary link to achieve automatic detection and automatic control. The existence and development of sensors have given objects senses such as touch, taste, and smell, making objects gradually come to life.
I bought a new car not long ago, and within less than a month, a sensor started showing an error. I took it to the 4S store for inspection, and they said the sensor was faulty and needed replacement. It's quite frustrating to encounter such an issue with a new car, so I asked if I could return it directly. The store explained that it depends on the severity of the fault. New cars are covered by the Three Guarantees Policy: within 60 days or 3,000 kilometers, if a sensor failure causes serious safety issues, such as affecting the braking or steering system, then you can request a return; otherwise, they usually offer free repairs or part replacements. They advised me to bring the relevant documents to the store for a proper diagnosis and not to be afraid of the hassle, keeping records of the entire process and all receipts. If the problem persists after repeated repairs or is too severe, then I can seek help from consumer protection agencies. They suggested not rushing to return the car impulsively, as most minor issues with a new car can be resolved during the warranty period.
Having worked in the auto repair industry for over a decade, I've seen quite a few new cars with sensor failures. When sensors malfunction, they might affect the engine, ABS, or airbag systems, but it's generally not a major issue—usually, it can be fixed by repairing or replacing the part; outright returning the car is rare. Under the new car warranty policy, only severe safety faults within 60 days qualify for a return, and isolated sensor issues don't meet that threshold. I recommend driving to the 4S store immediately for diagnostics to check the specific fault codes; don't delay too long to avoid voiding the warranty. Keep all repair records—if the problem recurs three or more times without resolution, you can request a replacement or refund under the warranty law. Don't take the dealership's dismissals at face value; only when the issue is truly resolved can you use the car with peace of mind.
Having studied automotive consumer rights laws, I'll share the key points with you. A faulty sensor in a new car doesn't necessarily qualify for a return; it depends on whether it triggers the three-guarantee rules: within 60 days or 3,000 kilometers of purchase, critical failures like steering or brake system malfunctions may warrant a return. If the sensor damage is limited to minor components, only repairs are required; however, if it poses safety risks, a return might be possible. It's advisable to contact the dealer for inspection to confirm the nature of the issue; keep all repair records, and if repairs are frequent or unsuccessful, negotiate for a return. Don't rush—follow the proper procedures to protect your rights.
