A great way to ruin your day is to have your diesel engine parts or diesel injection pump go out on you. It's even worse when the parts aren't warrantied; or worse still, when the parts ARE warrantied by the manufacturer but your local dealership doesn't want to warranty the parts for you.
It's sometimes difficult to realize that dealerships are not directly related to the brand of vehicles they sell. Though you hold high regard for the automaker of the car you purchased, the dealership can fall short of those high standards. Automakers try very hard to get their dealers to be honest and good to their customers (it affects their brand image a great deal), but still sleazy dealerships persist.
Here are some tips to get warranty work done on your vehicle:
1. Know Your Warranty: The owner's manual for your vehicle will have a warranty section, or a separate warranty pamphlet. There are often separate warranty terms for different parts of your vehicle; an example is a Drivetrain Warranty. Make sure that the part in question is covered under the manufacturer's warranty, and that your vehicle is within the warranty parameters.
2. Be Polite But Firm: If a dealer argues with you that the part is not under warranty when it clearly is, ask politely if you can check the warranty section of your manual. If they are still being resistant, nicely ask if they would like you to call the automaker to get authorization for them. Maintain an attitude of trying to work to solve the problem, not trying to accuse the dealer. Unfortunately your best bet of getting the problem fixed lies with the dealer, so make sure to remain polite and genial but firm.
3. Call The Automaker: If the dealer still refuses, you can always repeat the process at a different dealer in hopes of getting better service. If not, however, it may be necessary to contact your automaker and let them know of your experience. They often have national and regional telephone numbers; check your automaker's main website and search for the regional telephone number (if you can get it). Once on the phone, still remain polite and calm and do not badmouth the dealer. You do not want to be labeled as one of those "insane customers" so it's best to keep your cool and emphasize you are just trying to resolve an issue with your vehicle, and you need help.
4. Lemon Laws: If all else fails, you might need to get help from a lawyer. There are different laws for manufacturer's warranties in each state; finding out how many issues, and what kind of issues, you need to be experiencing to qualify could be useful to you. At this point you need to weigh the cost of lawyer's fees with the cost of buying a new part at your expense.
Hopefully, you will never need to follow all of these guidelines to get warranty work done on your vehicle. It can be an extremely frustrating experience but hopefully, armed with the facts, you'll get your vehicle taken care of.
