Erwin Paré has some simple advice for truck owners who want to make warranty claims go more smoothly: read the fine print.

“Believe me, I don’t like it either when something unexpected happens to your truck and you’re out of commission,” says Paré, a partner and service manager at 401 Mack in Windsor, Ont. “But what really frustrates me is seeing a guy walk in, make a warranty claim on something that isn’t covered, and then call his truck a piece of junk and us crooks when we tell him that the claim’s not acceptable. You can avoid hassles if you take time to understand what the warranty covers.”

Indeed, an estimated 3% of the purchase price of a new truck will be returned in warranty reimbursement-if you pay attention to coverage and claims.

A “basic” truck warranty covers all but service parts (filters, windshield wipers, etc.). Issues that cause the most confusion include coverage of parts and labor, whether coverage is 100% or prorated over time and mileage, or if there is a limit and/or deductible. Ask about “collateral” damage: if a covered part causes others to fail, will the seller cover all repair and replacement costs?

Remember, when you buy your truck, the warranty has value, too. You may be able to negotiate extra coverage when haggling price, and be sure to get all promises in writing.

What’s In, What’s Out:

Read between the lines when you study your warranty-it’s just as important to know what your warranty doesn’t cover.

Breakdowns caused by driver abuse, improper maintenance, misapplication, and unauthorized modifications generally aren’t covered. Some extended-protection programs pay for towing and a substitute vehicle; reimbursement for lost revenue is rare.

Preventive maintenance isn’t covered by warranty. Replacement or retrofit parts not sold by the original manufacturer are excluded, although they may have warranties of their own. Damage caused by failure of those parts may also be limited or excluded.

Some items-major powertrain components, tires, or even the driver’s seat, for example-will have warranties that go above and beyond what the truck manufacturer offers. If you’re not aware they exist, you may end up needlessly paying for a repair.

At the Shop:

Avoid surprises by re-reading your warranty before you decide to go ahead with a repair. Never assume a part or component isn’t covered, and keep thorough maintenance records-they can show failure patterns. If you’re authorized to do your own warranty work, make sure mechanics are properly trained to do the job-and to file the right paperwork and tag parts that are warranty candidates. Appoint one person to keep track of warranty coverage, handle paperwork, and follow-up on claims.

Avoid tough-to-diagnose problems. Strange noises and odd vibrations? Go to the dealer. Manufacturer “helplines,” for no charge or a nominal fee, can direct you or your drivers to the nearest authorized repair centre. Some operators can answer warranty questions, arrange towing or roadside service, and, if needed, connect you with a dealer or repair shop.

If the dealer can’t find a problem or won’t do anything, document the complaint and response-a failure may occur after the warranty has expired. If you don’t get help, go to the manufacturer. Describe the problem, what you’ve done to resolve it and what solution you want. If you are refused and feel you have a valid claim, don’t give up.
