Can a New Car Be Replaced if the Warning Light Comes On?
2 Answers
New car warning lights coming on does not qualify for a car replacement unless the replacement conditions are met. The illumination of a car warning light does not necessarily indicate a fault in the vehicle. Some are false alarms, such as being curious about the purpose of a certain plug, unplugging and then reconnecting it. The ECU will issue a warning and trigger the warning light for such improper operations, but the vehicle itself has no issues, and simply clearing the fault code will suffice. Car warning lights include: oil pressure warning light, coolant temperature indicator, engine fault light, brake system fault light, low oil pressure warning light, power steering warning light, ABS warning light, electronic stability control system indicator, and seat belt indicator.
I experienced a warning light issue within two months of buying my car, and I was so nervous at the time that I thought I might have to replace the vehicle. To be honest, most new car warning light activations don't actually meet the standards for vehicle replacement. According to China's Automobile Three Guarantees Policy, only serious safety performance failures - such as engine seizure or brake failure - that cannot be fixed after two or more repair attempts during the warranty period qualify for replacement. Most of the time, warning lights are just sensor false alarms or fuel quality issues, which can be resolved by clearing the fault code or replacing a part. In my case, it was caused by a loose fuel cap that triggered abnormal exhaust detection - the dealership simply tightened it and reset the system with their computer. I recommend first getting a comprehensive inspection at an authorized dealer, keeping all maintenance records, and only pursuing legal action if it's truly a major defect.
