2018 Chevrolet Silverado 1500 Factory Warranty

Here is a paragraph summarizing the expired warranties from the factory warranty document:
– The 3 year/36,000 mile Bumper-to-Bumper warranty has expired, as the vehicle is a 2018 model and it is now 2023. This covered the entire vehicle except for some exclusions.
– The 5 year/60,000 mile Powertrain warranty may have also expired, as we are in 5th year of this year. This covered the engine, transmission, drive systems, and more.
– The 6 year/100,000 mile Corrosion Perforation warranty is still active, since it is still within 6 years from the 2018 model year. This covered rust through perforation of sheet metal.

In summary, some of the factory warranties have expired on this 2018 Chevrolet based on the time and mileage limits listed in the owner’s manual. The owner would now be responsible for any repairs or required maintenance.
If you are confused about what each of the factory warranties cover for your Chevrolet, I recommend checking out our article “The Ultimate Guide to Car Warranties.” This guide explains in detail what is included in the Basic, Powertrain, Corrosion Perforation, Air Conditioning, Paint, Battery, Tire, Federal Emissions, and California Emissions warranties that come standard with new Chevrolet vehicles.
All of these warranties fall under the overarching Factory Warranty provided by Chevrolet. Our guide makes it easy to understand exactly what components and repairs are covered under each warranty. Knowing what is covered by the Factory Warranty can help owners understand if a repair is covered or if they will need to pay out of pocket. Our ultimate guide takes the confusion out of deciphering car warranties so you can be informed about your vehicle’s coverage.
Basic Warranty
The New Vehicle Limited Warranty, also known as the basic warranty, does not cover damage caused by accidents, misuse, alterations, lack of maintenance, or environmental issues. It also does not cover normal wear items like brake pads, wiper blades, or tires. This comprehensive warranty covered the entire vehicle except for some exclusions when the car was brand new.
However, this basic warranty expired in 2021, after 3 years from the 2018 model year of this Chevrolet. At that point, the 36,000 mile limit may not have been reached, but the time limit of 3 years superseded the mileage limit, voiding the basic warranty coverage. Now beyond the expiry, any repairs or replacements needed on this 2018 Chevrolet would not be covered by the original New Vehicle Limited Warranty that came with the car when new.
Powertrain Warranty
The powertrain warranty covers the engine, transmission, drive systems, and more specifically the engine block, cylinder heads, timing gears, engine mounts, turbocharger, seals, gaskets, and electrical components. This protects critical components that make the vehicle move.
However, this 5-year/60,000-mile powertrain warranty will expire in 2023 for this 2018 Chevrolet model, as we are in the 5th year of expiration, some of the warranties have not expired. However, if you have over 60,000 on the vehicle your warranty has expired. Repairs needed on the powertrain components after 2023 would not be covered by the original factory powertrain warranty.
Corrosion Perforation Warranty
The rust perforation limited warranty covers rust through the perforation of any original body sheet metal panels. If a hole rusts completely through the sheet metal due to corrosion, this would be covered. This 6-year/100,000-mile rust perforation limited warranty will expire in 2024 for this 2018 Chevrolet model since 6 years haven’t passed since its original in-service date. If the mileage limit was reached, the warranty would be void. Any rust-through perforation issues arising after 2024 would not be covered by the original factory rust perforation limited warranty.
Air Conditioning Warranty
The air conditioning warranty covers the compressor, condenser, evaporator, receiver dryer, blower motor, high/low-pressure cut-off switches, accumulator, related hoses and lines, and refrigerant leaks. This covers repairs needed to the AC system due to defects.
However, this 3-year/36,000-mile air conditioning warranty expired in 2021 for this 2018 Chevrolet model, as 3 years have passed since its original in-service date. The mileage limit was likely not yet reached, but the time limit of 3 years was superseded, voiding this air conditioning coverage. Any AC system repairs needed after 2021 would not be covered by the original factory air conditioning warranty.
Battery Warranty
The battery warranty covers any defects in the materials or workmanship of the original battery installed in the vehicle. However, it does not cover damage from improper maintenance, freezing, fire, collision, or explosions. This battery coverage falls under the New Vehicle Limited Warranty, also known as the bumper-to-bumper warranty, for 3 years/36,000 miles.
For this 2018 Chevrolet model, the 3-year time limit was reached in 2021, voiding the battery warranty coverage even if the mileage limit was not yet met. Any battery replacement needed after 2021 would not be covered under the original factory battery warranty that came with the new vehicle.
Tire Warranty
The tire warranty covers defects in the material or workmanship of the original tires installed on the new vehicle. However, it does not cover normal wear and tear, road hazard damage, improper inflation or use damage, or cosmetic issues like discoloration. This coverage is for 3 years/36,000 miles under the New Vehicle Limited Warranty.
For this 2018 Chevrolet, the 3-year time limit expired in 2021, even if the mileage limit was not yet reached. After 2021, any replacements or repairs needed to the original tires would not be covered under the factory tire warranty that came with the vehicle when new.
Federal Emissions Warranty
The Federal Emissions Warranty covers repairs to specific emission-related parts like the catalytic converter, engine control module, oxygen sensors, and more. However, it does not cover issues caused by poor maintenance, misuse, or accidents.
For this 2018 Chevrolet, the warranty on most emission components expired in 2020, after 2 years from the original in-service date. The 8-year/80,000-mile coverage for the catalytic converter and engine control module will expire in 2026. Any emission-related repairs needed after 2020 or 2026 depending on the part would not be covered by the original Federal Emissions Warranty that came with the new vehicle.
The Clean Air Act
The Federal Clean Air Act aims to reduce air pollution from vehicle emissions. Under this act, vehicle manufacturers must cover repairs to emission-related parts for at least 2 years or 24,000 miles. For this 2018 Chevrolet, the Clean Air Act emissions warranty expired in 2020, after 2 years from the original in-service date.
While the Clean Air Act required this coverage when the car was new, any emission system repairs needed now in 2023 or later would not be covered under the original emissions warranty. However, the Clean Air Act standards may still require Chevrolet to repair or replace some emission-related components, even though the warranty has expired. Vehicle owners should check with Chevrolet to see if any repairs may be covered under the Clean Air Act after their warranty has ended.
California Emissions Warranty
The California Emissions Warranty covers repairs to specific emission-related parts like the catalytic converter, engine control module, oxygen sensors, and more. However, it does not cover issues caused by poor maintenance, misuse, or accidents.
For this 2018 Chevrolet, the 3-year/50,000-mile warranty on most emission-related parts expired in 2021, after 3 years from the original in-service date. The 7-year/70,000-mile coverage for certain specified components will expire in 2025. Any emission-related repairs needed after 2021 or 2025 depending on the part would not be covered under the original California Emissions Warranty that came with the new vehicle.

Extended Warranties

Extended Warranty Available Upon Car Purchase
