ASE C1 Warranty, Contracts, Bulletins, Recalls — Questions and Answers
Question 1: A customer has an intermittent hesitation on acceleration. The service consultant finds a technical service bulletin (TSB) from the manufacturer that describes the same symptom on this model. Which statement best describes the TSB?
- It is a safety recall, so the repair must be done free on any vehicle
- It requires the manufacturer to notify every registered owner by mail
- It gives repair information for a known problem, and coverage depends on the vehicle's warranty status (Correct answer)
- It applies only to vehicles that have already been repaired once for the same concern
Correct answer: It gives repair information for a known problem, and coverage depends on the vehicle's warranty status
A TSB is a manufacturer's repair guide for a known condition. It is not a recall, so whether the repair is free depends on the vehicle's warranty coverage.
Manufacturers issue technical service bulletins to tell technicians how to diagnose and fix known problems, such as drivability concerns, noises or software updates. A TSB does not mean there is a safety defect, and owners are not normally notified. If the vehicle is still under warranty, the TSB repair is usually covered. If not, the customer usually pays unless the manufacturer has extended coverage. A good consultant checks for TSBs early because they can save diagnostic time.
Question 2: A customer wants to know if their used vehicle has any open safety recalls. Which source lets the consultant check this by the vehicle's VIN?
- The NHTSA recall lookup or the manufacturer's dealer recall system (Correct answer)
- The vehicle's original window sticker
- The state emissions inspection report
- The service contract administrator's claims portal
Correct answer: The NHTSA recall lookup or the manufacturer's dealer recall system
NHTSA's VIN-based recall lookup and the manufacturer's dealer system both show whether a specific vehicle has unrepaired safety recalls.
Safety recalls are reported to the National Highway Traffic Safety Administration (NHTSA). Anyone can enter a 17-character VIN in NHTSA's recall lookup tool to see open (unrepaired) recalls. Dealers can check the same status, plus campaign details, through the manufacturer's warranty or service information system. Checking recall status at every visit is a best practice because a car's owner may change and recall letters can be missed. The window sticker and emissions reports do not track recall completion.
Question 3: A customer bought a used vehicle with no remaining factory warranty. The VIN check shows an open safety recall on the airbag inflator. How should the consultant handle the recall repair?
- Charge the customer, since the factory warranty has expired
- Charge only for labor, since the manufacturer supplies the parts
- Ask the customer to file the recall claim with their service contract
- Perform the recall repair at no charge to the customer (Correct answer)
Correct answer: Perform the recall repair at no charge to the customer
Safety recall remedies are done free by the manufacturer's dealers, whether or not the warranty has expired and whether or not the customer is the original owner.
When a manufacturer decides that a vehicle has a safety-related defect, federal law requires it to notify owners and provide a free remedy. The remedy can be a repair, a replacement or a refund. Recall coverage applies to the vehicle, so second and later owners are covered too, and it does not depend on warranty time or mileage. The consultant should schedule the recall repair, confirm parts are available, and record the completed campaign so the vehicle's record is updated.
Question 4: How is a vehicle service contract different from a manufacturer's new-vehicle warranty?
- A service contract is required by federal law on every new vehicle
- A service contract is bought separately for an additional price and covers repairs according to its own terms (Correct answer)
- A service contract covers only safety recalls and emissions parts
- A service contract can be offered only by the vehicle manufacturer
Correct answer: A service contract is bought separately for an additional price and covers repairs according to its own terms
A warranty comes with the vehicle at no added cost. A service contract is an optional agreement the customer buys separately, and its coverage is set by its own terms.
Under the Magnuson-Moss Warranty Act, a warranty is part of the basis of the sale and is included in the vehicle's price. A service contract, often called an 'extended warranty', is sold separately for an extra charge. It can be offered by the manufacturer, the dealer or a third-party company. Coverage, deductibles, exclusions and claim procedures depend on the contract, so the consultant must read the specific contract terms instead of assuming it matches the factory warranty.
Question 5: A customer's in-warranty vehicle has an engine failure. The customer had every oil change done at an independent shop and kept the receipts. What is the correct position on warranty coverage?
- Coverage is void because the maintenance was not done at a dealer
- Coverage applies only if the customer pays a deductible
- Coverage cannot be denied just because an independent shop did the maintenance (Correct answer)
- Coverage depends on whether the independent shop used genuine dealer filters
Correct answer: Coverage cannot be denied just because an independent shop did the maintenance
Federal law generally prohibits voiding a warranty just because maintenance or parts came from someone other than the dealer, unless that service or part caused the failure.
The Magnuson-Moss Warranty Act generally prevents a manufacturer from making warranty coverage depend on using a particular brand of parts or service provider. Exceptions apply when those parts or services are provided free. Owners may have maintenance done anywhere, as long as it follows the manufacturer's schedule and specifications. The warranty can be denied for a failure that was actually caused by improper service or a defective aftermarket part. Maintenance records, like this customer's receipts, help prove the vehicle was cared for correctly.
Question 6: Under federal emissions warranty requirements for light-duty vehicles, which components are covered for 8 years or 80,000 miles?
- All exhaust pipes, hangers and mufflers
- Specified major emission control components such as the catalytic converter and the engine control module (Correct answer)
- Oxygen sensors and spark plugs only
- Any part that causes the check engine light to illuminate
Correct answer: Specified major emission control components such as the catalytic converter and the engine control module
The federal emissions performance warranty covers specified major emission control components, including the catalytic converter and the engine control computer, for 8 years or 80,000 miles.
Federal law provides two emissions warranties on light-duty vehicles. The general emissions warranty is 2 years or 24,000 miles. Specified major emission control components, such as the catalytic converter, the electronic emissions control unit (ECU/PCM) and the onboard emissions diagnostic device, are covered for 8 years or 80,000 miles. Some states, such as California, require longer or broader coverage. Consultants should check emissions coverage before quoting a customer-pay repair on these parts.
Question 7: A vehicle covered by a third-party service contract needs a transmission repair. What should the service consultant normally do before the technician starts the repair?
- Start the repair and send the bill to the contract company afterward
- Collect full payment from the customer and tell them to request reimbursement
- Ask the manufacturer to approve the claim under the factory warranty
- Contact the contract administrator to get authorization for the covered repair (Correct answer)
Correct answer: Contact the contract administrator to get authorization for the covered repair
Most service contracts require prior authorization from the administrator. If repairs start without approval, the claim may be denied.
Service contract administrators usually require the shop to call or submit a claim before repairs begin. The shop provides the diagnosis, the cause of failure and an estimate. The administrator may ask for an inspection, then authorizes covered parts and labor, often at set labor times or part prices. The consultant should also explain any deductible and any parts the contract does not cover, such as noncovered items or diagnostic time, so the customer knows what they will pay. Skipping authorization is a common reason claims are denied.
Question 8: A vehicle at 25,000 miles is still under its 3-year/36,000-mile basic warranty. Which repair would most likely be customer-pay?
- Replacing worn front brake pads (Correct answer)
- Replacing a power window motor that has stopped working
- Repairing an inoperative A/C compressor clutch
- Replacing a faulty instrument cluster
Correct answer: Replacing worn front brake pads
Basic warranties cover defects in materials and workmanship, not normal wear items like brake pads.
A new-vehicle basic, or bumper-to-bumper, warranty pays to repair parts that fail because of a defect in materials or workmanship. Parts that wear out in normal use are usually excluded or have only short coverage. Examples include brake pads and rotors, wiper blades, filters and clutch linings. Routine maintenance is also customer-pay. A failed window motor, A/C clutch or instrument cluster at 25,000 miles points to a defect and would normally be covered. Consultants should explain these exclusions clearly to avoid customer disputes.
Question 9: A manufacturer announces that a specific component on certain models will now be covered for 10 years, longer than the original warranty, because of a known durability problem. The problem is not safety-related. What is this type of action usually called?
- A federal safety recall
- A warranty extension or special coverage program (Correct answer)
- A technical service bulletin
- A service contract upgrade
Correct answer: A warranty extension or special coverage program
A warranty extension or special coverage program lengthens coverage on a specific part for a non-safety issue. It is not a safety recall.
Manufacturers sometimes respond to a known non-safety problem by extending warranty coverage on one component. They do this through a special coverage program, warranty extension or customer satisfaction campaign. Unlike a safety recall, the vehicle is repaired only if the part fails within the extended time or mileage, and NHTSA does not require owners to be notified the same way. Consultants should check the manufacturer's system for these programs. A repair that looks like customer-pay may actually be covered, and some programs reimburse customers who already paid.
Question 10: For a warranty claim to be accepted, what should the repair order clearly document?
- Only the total labor time billed and the technician's ID number
- The customer's preferred payment method and phone number
- The customer's concern, the cause found, and the correction performed (Correct answer)
- The service consultant's sales commission code
Correct answer: The customer's concern, the cause found, and the correction performed
Manufacturers require documentation of the concern, cause and correction (the '3 Cs') to verify that a warranty repair was valid.
Warranty claims are audited, and claims without proper documentation can be charged back to the dealer. The repair order should record the customer's concern in their own words, the cause the technician found with supporting diagnostic results, and the correction performed, with labor operation codes and parts. Accurate mileage, VIN and dates are also needed. The service consultant writes the concern accurately at write-up, which is the start of a claim that can be paid.
