Covered for 3 years/36,000 Miles
GM is committed to ensuring satisfaction with your new vehicle. Your dealer also wants you to be completely satisfied and invites you to return for all your service needs, both during and after the warranty period. To help keep things in proper working order, Chevrolet will warrant each 2012 model year Chevrolet passenger car, light-duty truck, crossover or van for 3 years or 36,000 miles (whichever comes first; see dealer for details) with no deductible, from the original in-service date of the vehicle, for warrantable repairs that are required as a result of defects due to material and/or workmanship to the powertrain components.
Powertrain Coverage
In addition to the 3-year/36,000 mile protection, many of your powertrain components are protected even further with coverage extending to 5 years or 100,000 miles, whichever comes first.
Engine
Engine coverage includes all internally lubricated parts, engine oil cooling hoses, and lines. Also included are all actuators and electrical components internal to the engine (e.g., Active Fuel Management valve, lifter and oil manifold) cylinder head, block, timing gears, timing chain, timing cover, oil pump/oil pump housing, OHC carriers, valve covers, oil pan, seals, gaskets, manifolds, flywheel, water pump, harmonic balancer, engine mount, turbocharger, and supercharger. Timing belts are covered until the first scheduled maintenance interval. Exclusions: Excluded from the powertrain coverage are sensors, wiring, connectors, engine radiator, coolant hoses, coolant, and heater core. Coverage on the engine cooling system begins at the inlet to the water pump and ends with the thermostat housing and/or outlet that attaches to the return hose. Also excluded is the starter motor, entire pressurized fuel system (in-tank fuel pump, pressure lines, fuel rail(s), regulator, injectors, and return line), as well as the Engine/ Powertrain Control Module and/or module programming.
- For trucks equipped with a 6.6L Duramax diesel engine, the diesel engine, except those items listed under “What Is Not Covered” later in this section, is covered for 5 years or 100,000 miles, whichever comes first.
Transmission/Transaxle
Transmission and transaxle coverage includes all internally lubricated parts, case, torque converter, mounts, seals and gaskets, as well as any electrical components internal to the transmission/transaxle. Also covered are any actuators directly connected to the transmission (slave cylinder, etc.). Exclusions: Exclusions from the powertrain coverage include cooling lines, hoses, radiator, sensors, wiring, and electrical connectors. Also excluded are the clutch and pressure plate, as well as any Transmission Control Module and/or module programming.
Transfer Case
Transfer case coverage includes all internally lubricated parts, case, mounts, seals and gaskets, as well as any electrical components internal to the transfer case. Also covered are any actuators directly connected to the transfer case, as well as the encoder motor. Exclusions: Excluded from the powertrain coverage are transfer case cooling lines, hoses, radiator, sensors, wiring, and electrical connectors, as well as the transfer case control module and/or module programming.
Drive Systems
Drive system coverage includes all internally lubricated parts, final drive housings, axle shafts and bearings, constant velocity joints, propeller shafts and universal joints. All mounts, supports, seals, and gaskets, as well as any electrical components internal to the drive axle. Also covered are any actuators directly connected to the drive axle (e.g., front differential actuator). Exclusions: Excluded from the powertrain coverage are all wheel bearings, drive wheel front and rear hub bearings, locking hubs, drive system cooling, lines, hoses, radiator, sensors, wiring, and electrical connectors related to drive systems, as well as any drive system control module and/or module programming.
Sheet Metal
GM vehicles are designed and built to resist corrosion. All body and sheet metal components are warranted against corrosion for 3 years or 36,000 miles, whichever comes first. Plus you’re protected even further from rust-through corrosion for a minimum of 6 years/100,000 miles (whichever comes first). Application of additional rust-inhibiting materials is not required under the corrosion coverage and none is recommended. See your GM dealer for terms of this limited warranty.
Emission Control Systems
Defects and performance for car and light-duty truck emission control systems are covered for the first 2 years or 24,000 miles, whichever comes first. From the first 2 years or 24,000 miles to 3 years or 36,000 miles defects in material or workmanship continue to be covered under the New Vehicle Limited Bumper-to-Bumper Warranty coverage. Specified major components are covered for the first 8 years or 80,000 miles, whichever comes first. Defects and performance for heavy duty truck emission control systems including those found in 6.6L Duramax® Diesel Engines are covered for the first 5 years or 50,000 miles, whichever comes first.
- Refer to your Warranty and Owner Assistance Information booklet for California emission control system warranty details.
Tires
The tires supplied with your vehicle are covered by General Motors against defects in material or workmanship under the Bumper-to-Bumper Limited Warranty coverage. Wear-out is not considered a defect, and it may occur before the vehicle warranty expires. In this case, the owner is responsible for purchasing replacement tires, or seeking coverage solely from the tire manufacturer. For vehicles within the Bumper-to-Bumper Limited Warranty coverage, defective tires will be replaced on a prorated adjustment basis according to the mileage-based schedule in your Warranty and Owner Assistance Information booklet. After your New-Vehicle Limited Warranty expires, you may still have prorated warranty coverage on your original equipment tires by the tire manufacturer.
Towing
Towing is covered to the nearest Chevrolet dealer if your vehicle cannot be driven because of a warranted defect.

True, but it has always been that way, right? With this being the case it begs this question: Will you buy the extended warranty? If so, will it be purchased when you sign the purchase agreement or will you wait?

When did the Corvette come with a different warranty then the rest of Chevrolet? At least now it includes 2 yrs of maintenance. I will be seriously considering an extended warranty but almost certainly not at signing.

I don't expect anything other then the standard warranty but I don't like to assume. I never realized you could buy the extended warranty from Chevy after the time of sale. I know there's plenty of aftermarket companies that offer warranties.When did the Corvette come with a different warranty then the rest of Chevrolet? At least now it includes 2 yrs of maintenance.

Is the 2 years of service included for sure?

Yes the 2 years service is new and included. You can buy the GM PP at various times from new through at least when there is a little time left on your original warranty (and of course the pricing varies as well). I have done it both ways as well as not at all, kind of depending on how long I anticipate keeping a car, the complexity of the car and original warranty. I also found you can get the identical plan discounted through other GM dealers which is very nice, since the plan it self always comes from GM and is honored by all GM dealers. If you end up being interested in a GMPP check the internet for the best price at that time. Update: Just saw today that some states will not allow you to purchase the GMPP out of your state for your car.
Fortunately it is only a handful of states, unfortunate if you want a GMPP and you are in one of those states and your dealer wants to charge you full price.

The only thing I have any concern withis the electronics. I'm an engineer for an aerospace electronics suppier. If ther is a entended warrenty that covers the ellectronics I will buy it. They are doing there best to test it but unfortuneatly they can't realistically prevent what will fail after 4 years in the winters of VT or the summers of Texas.

I don't have the list but last time I checked California was one. I also believe the situation is dynamic. Once you have your beauty you can check.

It will, but it will not be Mobil 1. I believe it will be a GM branded Dexos that is a synthetic blend.

I'm wondering if I should have the oil changed straight away to full synthetic? Any thoughts?

I've heard so many things regarding oil type and break in and other then changing the oil at around 500 miles it doesn't matter. Ill stay at what Chevy suggests just because of the 2 year free service plan but once that's over ill change to amsoil synthetic.
