Recall, TSB or warranty extension: what's the difference?

Three documents that get mixed up

Owners hear all three terms at the service desk, often in the same visit. They aren't interchangeable, and the difference decides who pays.

• A safety recall is filed with NHTSA when a manufacturer or the agency decides a defect poses an unreasonable safety risk, or the car fails a federal safety standard. The fix is free by law.
• A technical service bulletin (TSB) is a communication from the manufacturer to its dealers about a problem and how to repair it. It can cover safety or non-safety issues.
• A warranty or policy extension lengthens the manufacturer's coverage for a specific part or failure.

Recalls: safety, and free

NHTSA's recall booklet sets out when a recall is required: when a vehicle or part doesn't comply with a Federal Motor Vehicle Safety Standard, or when it has a safety-related defect. A defect counts as safety-related when it poses an unreasonable risk to safety and shows up across a group of vehicles of the same design or manufacture.

Once a recall is filed, the manufacturer has to notify owners by first-class mail within 60 days and fix the problem at no charge. The law lets it choose between repairing the car, replacing it, or refunding the price minus depreciation. There's an age limit: the free remedy isn't required for a car first sold more than 15 calendar years before the recall.

Across the vehicles on this site, NHTSA has 2,234 recall campaigns on file. Here's where they cluster:

The booklet also lists what isn't a safety defect. Radios that don't work, ordinary wear on brake pads, shocks, batteries and exhaust parts, cosmetic paint problems, non-structural rust and excessive oil consumption are on that list. None of those will get a recall, however common they are. That's why a model can draw thousands of complaints about something like oil burning and never see a recall for it.

TSBs: repair instructions for dealers

Manufacturers send dealers a steady stream of bulletins. A Federal Register notice NHTSA published in 2016 describes them as repair instructions for trained technicians. Some bulletins carry the steps for a recall repair, and many deal with problems that have nothing to do with safety: a rattle, a software glitch, a leak that keeps coming back.

Federal rules require manufacturers to send NHTSA copies of these communications, including warranty and policy extensions and product improvement bulletins, about any defect or failure beyond normal wear, whether it's safety-related or not. A 2012 law, MAP-21, then required NHTSA to post them publicly with a searchable index, and NHTSA announced in 2016 that it would do so.

Here's the part that matters at the service desk. The free-repair requirement in federal recall law applies to recalls. NHTSA's description of manufacturer communications makes no promise of a free repair for a bulletin. Whether you pay for a TSB repair depends on your warranty, or on whether the manufacturer has extended coverage for that problem.

Why a TSB is still worth finding

A bulletin that matches your symptom is useful even when you're paying. It tells the shop what the manufacturer has already worked out, which can save diagnostic time and steer the repair toward the known fix. To find them, search your year, make and model at nhtsa.gov/recalls and open the manufacturer communications results. NHTSA also offers a dashboard of manufacturer communications. The 2016 notice cautions that NHTSA's older bulletin summaries don't cover every bulletin a manufacturer writes, so an empty result isn't proof nothing exists.

Warranty extensions: coverage for one known problem

Sometimes a manufacturer extends its warranty on one part or one failure, beyond the original coverage. Manufacturers file these with NHTSA as "warranty and policy extension" communications, the same channel as bulletins, so they turn up in the same search.

Each extension comes with its own terms, so read the letter closely. And don't expect the VIN lookup to show one: NHTSA says its search leaves out manufacturer customer service and other non-safety campaigns.

Don't confuse an extension with an "extended warranty"

What dealers sell as an extended warranty is a different product. The Federal Trade Commission is blunt about it: a service contract, sometimes called an extended warranty, is not a warranty. It's a contract you buy, from the manufacturer, the dealer or an independent company, with its own deductibles and exclusions. A warranty extension comes from the manufacturer and covers one specific problem.

Which one covers my problem?

Work through it in order:

1. Run your VIN at nhtsa.gov/recalls. If an open recall covers your problem, the repair is free. Our VIN guide covers the details.
2. Check your warranty. If the car is still under the manufacturer's coverage, ask whether the problem falls under it before you pay.
3. Search manufacturer communications for your year, make and model. Look for a warranty extension first, then a bulletin that matches your symptoms.
4. Ask the dealer directly whether a campaign or extension applies to your VIN, and ask for the bulletin number if they cite one.
5. If the problem is a safety risk and nothing covers it, file a complaint with NHTSA. Our complaint guide shows how.

If you paid for a repair and a recall follows later, you may be owed that money back. See how recall reimbursement works.
