Texas Lemon Law for Cars: Qualifications, Filing, and Remedies

The Texas lemon law for cars lets you force a manufacturer to buy back, replace, or repair a new vehicle that keeps failing the same repair. The Texas Department of Motor Vehicles runs the process. To qualify, your vehicle generally must have gone through multiple failed repair attempts for the same defect within the first 24 months or 24,000 miles, and you must file your complaint within six months after that period closes.¹

Which Vehicles Qualify

The law covers new cars, trucks, vans, motorcycles, and all-terrain vehicles, along with towable recreational vehicles like travel trailers. It does not cover motorized RVs (Class A, B, and C motorhomes), agricultural equipment, or vehicles with a gross weight of 20,000 pounds or more.²

Leased vehicles qualify on the same terms as purchased ones, so long as they are new and still under the manufacturer’s original warranty.¹

Used vehicles are treated differently. If you bought a used car still covered by the manufacturer’s original factory warranty, you can file a warranty performance complaint with TxDMV, but the remedy is limited to repair assistance. Used vehicle owners cannot get a buyback or replacement. Extended service contracts and aftermarket warranties do not count as the original manufacturer’s warranty.¹

The Three Tests That Qualify a Vehicle as a Lemon

Texas creates a legal presumption that a manufacturer has had enough chances to fix your car if any one of three tests is met. All three share the same outer boundary: the repair attempts must have happened before either the express warranty expires or 24 months and 24,000 miles from delivery, whichever comes first.³

Four-repair test: the same defect has been brought in for repair four or more times and still is not fixed.
Serious safety hazard test: a defect that creates a real risk of collision or injury has been brought in for repair two or more times and still exists.
30-day test: the vehicle has been out of service for a cumulative total of 30 or more days because of defects that substantially hurt the vehicle’s use or market value. The days do not need to be consecutive, and any days when the manufacturer lends you a comparable loaner do not count.

In every case, the defect must substantially impair the vehicle’s use or market value, or create a serious safety hazard. A squeaky dashboard or a cosmetic scratch will not clear the bar. The law focuses on mechanical and safety failures that keep you from relying on the vehicle for normal driving.³

The Six-Month Filing Deadline

You must file your complaint within six months after whichever of these three events comes first: the manufacturer’s express warranty expires, 24 months pass from the date of purchase, or the vehicle reaches 24,000 miles. Miss the window and TxDMV will reject the complaint no matter how strong the defect claim is.¹

Notify the Manufacturer First

Before filing with TxDMV, you must send written notice to the manufacturer giving them one more chance to fix the vehicle. Send it by certified mail so you have proof of delivery. Identify the vehicle, describe the defect, and request a repair. This is a legal prerequisite; skip it, and TxDMV can reject the complaint.⁴

While you wait, pull together every repair order and service record you have. You will need the VIN, the dates and descriptions of each repair visit, and a clean timeline showing you meet one of the three qualifying tests. Incomplete documentation is where many claims fall apart.

Filing With TxDMV

Once the manufacturer has had its final chance and the problem remains, file the Lemon Law Complaint Form with a $35 non-refundable filing fee. The online portal is the fastest route; paper submissions go by mail to the Lemon Law Section in Austin.⁵

A case advisor first tries to negotiate a voluntary resolution between you and the manufacturer. Many cases end at this stage. If talks fail, TxDMV may send a technical expert to inspect the vehicle. Unresolved complaints get referred to the State Office of Administrative Hearings for a formal hearing, where you carry the burden of proof and present evidence first. An administrative law judge issues the final order.⁶

What You Can Get: Buyback, Replacement, or Repair

If the judge rules in your favor, the order requires the manufacturer to repurchase the vehicle, replace it with a comparable one, or complete the repair. Only new vehicles qualify for repurchase or replacement.¹

In a repurchase, the manufacturer buys the vehicle back for the full purchase price, including taxes, title, and license fees, minus a mileage-based deduction called the Reasonable Allowance for Use. In a replacement, the manufacturer provides a comparable vehicle with the same make, model, and accessories; you pay the difference only if you choose upgrades.⁷

Either way, the manufacturer must also reimburse you for reasonable incidental costs caused by the defect, such as rental cars, towing charges, and meals or lodging if the vehicle broke down on a trip.

How the Mileage Deduction Works

Texas assumes a useful life of 120,000 miles and splits your driving into two periods with different rates.⁸

Miles driven before you first reported the defect are charged at the full rate: purchase price multiplied by those miles divided by 120,000. Miles driven after you reported the defect through the hearing date are charged at half that rate, because the vehicle was defective during that stretch.

For example, if you paid $40,000 for a truck, first reported the defect at 5,000 miles, and the hearing happens at 15,000 miles, the deduction works out to about $3,333, leaving a refund around $36,667 before incidental costs are added back. Reporting the defect early protects your refund, since every mile you drive before the first complaint counts at the higher rate.

If There Is a Loan on the Vehicle

When a vehicle still has a loan balance, the refund is divided between you and the lienholder based on each party’s interest. In practice, the loan gets paid off from the refund first, and you receive what remains.⁷

Appeals and the 150-Day Escape

Either side can seek judicial review in a Travis County district court. The court applies the substantial evidence standard, reviewing whether the record reasonably supports the judge’s decision rather than holding a new trial. A petition must be filed within 30 days after the order becomes final.⁹

There is one other route to court. If TxDMV does not issue a final order within 150 days of your complaint, the agency must notify you in writing that you have the right to file a civil lawsuit directly. That prevents a claim from stalling indefinitely.¹⁰

The Federal Magnuson-Moss Alternative

The state lemon law is not your only option. The federal Magnuson-Moss Warranty Act covers any consumer product sold with a written warranty, including vehicles, new or used. You can bring a claim if the manufacturer fails to repair a defect after a reasonable number of attempts and the vehicle does not meet the quality you would expect from a comparable product.¹¹

The federal law has a longer filing window, generally up to four years from purchase, and does not require you to go through TxDMV. If the manufacturer’s warranty requires an informal dispute resolution program first, you may need to complete that step before suing.¹²

The biggest practical advantage of a Magnuson-Moss claim is fee shifting. If you prevail, the court can order the manufacturer to pay your attorney’s fees and court costs on top of compensation for the vehicle’s diminished value.¹³

Because the state and federal claims protect different things with different deadlines, many owners pursue both. The state process is simpler and does not require an attorney; the federal route offers broader remedies but runs through the court system.
