Car warranties are excellent protection against manufacturing defects or workmanship errors. With a car warranty, manufacturers promise that within a certain time frame, your new car purchase will function as promised. But car warranties are not blank checks from the manufacturer to pay for any necessary repairs. Certain things you do can cancel the agreement of the car warranty.
1. Don’t use the right fluids in your car.
When your car manual says to use a specific type of oil (or any other type of fluid) in your car, use that type. They spend lots of money to figure out what will help the car work most efficiently, and they aren’t just “suggesting,” they are insisting. You might find a better deal on a cheaper type, and in the interest of saving money, you could be tempted to go against the manufacturer’s instructions. But here’s a warning for you – if you use the wrong type of oil and your engine seizes up, your car warranty won’t cover the repair.
2. Don’t install the right tires on your car.
You might think it’s really cool to “pimp your ride” by adding some special modifications to your car, like “dubs” or special lifts that change the height of car with lift or lower kits. Unfortunately, your car was not designed to ride like that. Modified tires or a different center of gravity in your car can drastically alter the torque on your chassis and axle bearings. If your modifications can be traced as the root of a problem, your repair won’t be covered by your car warranty.
3. Don’t save your receipts.
You probably know that you aren’t required to go to your dealer for regular maintenance. What you may not know is that every time you take your car to another service center, you absolutely need to save your receipts. And not just your credit card slip. Make sure you leave with a detailed list of all the fluids, filters and other parts that were used during service. If there’s a contest over coverage on your warranty, the manufacturer can 1. claim that you didn’t service the vehicle according to maintenance instructions or 2. the service center didn’t use the correct parts. Save your receipts. If you’re not sure, go to the dealer. They are required by their contract with the manufacturer to keep very detailed record of any services performed.
4. Tow something.
Unless you own a heavy-duty truck that has a guaranteed capability to tow specific weights, don’t try it. If the manufacturer can prove you towed something, either a trailer or another vehicle — even a short distance — that could void your car warranty. Your car’s engine is probably not built to handle the strain of the extra weight, and any damages that occur after the tow would probably not be covered by your car warranty.
