Under what circumstances can spare parts not be covered by warranty during the warranty period?

During the car warranty period, as long as the malfunction or damage to parts occurs under normal usage conditions as specified, the manufacturer will provide free repair or replacement of the corresponding spare parts for the owner. The following situations are not covered by the warranty: 1. Failure to present the original valid warranty card and valid invoice; cases where the warranty certificate has been altered or falsified; 2. The entire vehicle is out of warranty, or wear-and-tear parts have exceeded their separate warranty period; 3. External factors causing the malfunction, unauthorized external repairs, incomplete maintenance records, unauthorized modifications, or the use of non-original parts may result in the warranty not being honored.
As a mechanic with over a decade of experience in the automotive industry, I've seen many cases where spare parts warranties became problematic. The most common issue is when car owners use non-OEM parts, such as cheap components bought online or aftermarket parts installed at roadside shops. Manufacturer warranties only cover their own products, so generic brands are definitely out of luck. Another frequent scenario is when DIY installations damage circuits or cause loose connectors – manufacturers will classify these as human-induced damages and refuse coverage. Components damaged in accidents, premature wear due to overload usage, or improper modifications like messy wiring from audio system upgrades often lead to failures. Don't forget scheduled maintenance either – I once saw a case where forgotten oil changes affected related components. My advice: read the manual carefully, stick to authorized service centers, and don't invite trouble by cutting corners.
I've owned my car for two years and have suffered losses from replacing parts myself. That time when the air conditioning pump failed, it was within the warranty period, but the 4S store said it wasn't covered because it was a non-original part—I bought a cheap second-hand one. Later, I found out a friend lost warranty on his suspension modification for using aftermarket parts. Mistakes in self-installation, like not tightening screws properly; misuse such as overloading the vehicle; damage from accidents; and wear-and-tear items like brake pads and tires with short lifespans listed in the manual aren't covered. Now, every long trip makes me nervous. I recommend regular check-ups to prevent small issues from turning into major crises.
Having handled warranty matters in this industry for many years, simply put, spare parts are not covered when they are non-original, improperly installed by private parties, or misused such as through excessive speed wear or accident damage. Wear-and-tear items like wiper blades and filters have shorter coverage, and neglecting scheduled maintenance leads to associated failures. Car owners should prioritize authorized channels and maintain clear records for verification purposes.
