Almost every used car on a Texas dealer’s lot has a window sticker that says either “AS IS – NO DEALER WARRANTY” or lists a warranty. That sticker, the Buyers Guide, is one of the most important documents in your purchase. It tells you who pays if something breaks after you drive away, and it becomes part of your sales contract.
There is also a common myth that you can return a car within three days if you change your mind. In Texas, that is generally not true. Here is what San Antonio shoppers should know about “as is” sales, warranties and return rights before signing.
Is a Used Car Warranty Required in Texas?
No Texas law requires a dealer to give a written warranty on a used car. What you get depends on how the car is sold, and the window sticker (the FTC Buyers Guide) tells you:
- “As Is – No Dealer Warranty”: the dealer isn’t responsible for repairs after the sale.
- “Dealer Warranty”: the Guide shows whether it’s full or limited, which systems are covered, and what share of repair costs the dealer pays.
Some newer used cars also still have part of the manufacturer’s original warranty left. That coverage follows the car, not the owner.
What the FTC Buyers Guide Is
Under the Federal Trade Commission’s Used Car Rule, dealers who sell more than five used vehicles in a 12-month period must display a Buyers Guide on every used vehicle they offer for sale. According to the FTC’s Dealer’s Guide to the Used Car Rule, the Guide must be posted where both sides can be read, such as on a side window or hanging from a mirror, and it can only be removed for a test drive.
The Buyers Guide tells you:
- Whether the vehicle is sold “as is” or with a warranty
- If there is a warranty, what percentage of repair costs the dealer will pay and which systems are covered
- To get all promises in writing, because spoken promises are difficult to enforce
- To ask to have the car inspected by an independent mechanic before you buy
- The dealer’s contact information for complaints

What “As Is” Really Means in Texas
The Texas Attorney General puts it plainly: “AS IS” means the vehicle does not have a warranty and the seller is under no obligation for repairs. If the transmission fails a week after the sale, the cost is yours.
Texas law allows these sales. Under Texas Business and Commerce Code Section 2.316, expressions like “as is” or “with all faults” generally exclude implied warranties. The same section also says that if you examined the goods as fully as you wanted before buying, or refused to examine them, there is no implied warranty for defects that the examination ought to have revealed.
“As is” does not give a seller permission to lie. The Texas State Law Library notes that the Texas Deceptive Trade Practices Act prohibits “false, misleading, or deceptive acts or practices” in a sale. If you believe you were deceived, talk to an attorney or contact the Attorney General’s consumer protection division.
Warranty Types You May See
The FTC’s consumer guide to buying a used car explains the main options:
- As Is – No Dealer Warranty: The dealer won’t pay for any problems or repairs after the sale.
- Implied warranties: Unwritten promises, such as the “warranty of merchantability” (the car will do what a car is supposed to do). These apply when a car isn’t sold “as is,” but you would still need to show that the problem existed at the time of sale.
- Full or limited warranty: A written dealer warranty. Most used car warranties are limited, and they may cover only certain systems, like the engine or transmission.
- Unexpired manufacturer’s warranty: Some newer used cars still carry factory coverage. Ask for the warranty documents and verify what’s left using the VIN.
One detail many buyers miss: the Buyers Guide overrides the contract. The FTC says that if the Guide shows a warranty but the contract says “as is,” the dealer must give you the warranty described in the Guide. If you negotiate any change in coverage, make sure it is written on the Buyers Guide and the contract.
How to Check If a Used Car Still Has Factory Warranty
- Find the VIN (on the dashboard by the windshield, the driver’s door jamb, and the title).
- Call a franchised dealer for that brand, or use the manufacturer’s owner website, and ask for the warranty “in-service date” and any remaining coverage.
- Compare the remaining time and miles to the odometer. Most factory coverage ends at a set number of years or miles, whichever comes first.
- Get anything you’re told in writing, and keep it with your purchase papers.
Service Contracts Are Not Warranties
A service contract, often sold as an “extended warranty,” is a separate product you pay for. The FTC points out an important rule: if you buy a service contract from the dealer within 90 days of buying a used car, the dealer can’t remove implied warranties on the systems that contract covers. Before buying one, ask what it covers, the deductible, the waiting period and how cancellation works.
At Trilux Motors, an optional SecureOne Vehicle Service Contract (administered by Marathon) may be available through Westlake Financial, subject to credit approval. It is never required to get approved or financed. Coverage levels, terms, waiting periods and exclusions are in the contract. Ask us for the details on a specific car.
Is There a 3-Day Right to Return a Car in Texas?
Generally, no. The Texas Attorney General states: “Under Texas Law, you do not have 3 days to cancel the purchase.” The Texas State Law Library agrees that no state law explicitly grants a right to return a car, and that once you sign a contract you are bound by its terms. The narrow three-day cancellation rights that exist typically do not apply to auto sales.
The exception is a return or cancellation policy the seller chooses to offer. If a dealer promises one, get it written into the paperwork before you sign.
Does the Texas Lemon Law Cover Used Cars?
Usually not in the way people hope. The Texas Lemon Law is aimed at defects covered by a manufacturer’s written warranty. According to TxDMV’s Lemon Law page, a used vehicle may still qualify for help under Texas warranty performance law if it is still covered by the manufacturer’s original warranty (not an extended service contract), or if the defect started and was reported to a dealer while that warranty was in effect and still exists. In those cases, repair assistance may be available. Keep every repair order.
Your Pre-Signing Checklist
- Read the Buyers Guide on the window and confirm which box is checked.
- Get every promise, such as a repair, a part replacement or a return option, written on the Buyers Guide or contract.
- Have an independent mechanic inspect the car before you buy. A vehicle history report does not show most mechanical problems.
- Run the VIN through NHTSA’s recall lookup for open safety recalls.
- Review every line of the contract, including fees and optional add-ons, and make sure there are no blank spaces.
Rules can change, so check the FTC, TxDMV or the Texas Attorney General for the latest guidance.

Used Car Warranty FAQs (Texas)
Do used cars come with a warranty in Texas?
Not automatically. Texas allows dealers to sell used cars “as is.” Check the FTC Buyers Guide on the window: it shows whether the car is sold as is or with a dealer warranty, and that Guide becomes part of your contract.
What does “as is” mean on a Texas used car?
It means the dealer isn’t promising to pay for repairs after the sale. Under Texas law, wording like “as is” generally excludes implied warranties. “As is” does not allow a seller to lie about the car.
Can I return a used car in Texas within 3 days?
Generally, no. The Texas Attorney General says Texas law doesn’t give you 3 days to cancel a car purchase. A return option exists only if the seller offers one in writing.
Does the Texas Lemon Law cover used cars?
Usually only if the problem is covered by the manufacturer’s original warranty, or started and was reported while that warranty was in effect. Extended service contracts don’t count. See TxDMV’s Lemon Law page.
Is an extended warranty the same as a warranty?
No. It’s a service contract, a separate optional product with its own terms, deductible and exclusions.
