The Tennessee lemon law, officially the Motor Vehicle Warranty Act, lets buyers and lessees of new vehicles demand a comparable replacement or a full refund when the manufacturer cannot fix a serious defect after a reasonable number of tries. It is codified at Title 55, Chapter 24 of the Tennessee Code, and it only works while the vehicle is still inside its warranty or its first year from delivery, whichever ends sooner.1Justia. Tennessee Code Title 55, Chapter 24 – Motor Vehicle Warranties
Who and What the Law Covers
The statute applies to new passenger vehicles and motorcycles sold or leased in Tennessee and subject to registration in Tennessee or another state. That covers cars, trucks, vans, SUVs, and motorcycles bought primarily for personal or family use.2Justia. Tennessee Code 55-24-101 – Chapter Definitions
Several things fall outside the law:
- Motor homes used as dwellings
- Lawnmowers and garden tractors
- Recreational and off-road vehicles
- Motorized bicycles
- Vehicles over 10,000 pounds gross vehicle weight
- Used vehicles of any kind
On the buyer side, the law protects the original purchaser or lessee, anyone the vehicle is later transferred to while the express warranty is still active, and anyone else entitled to enforce that warranty. Government entities are excluded. So are businesses that register three or more vehicles, which catches some small companies off guard: the cutoff is the number of vehicles registered, not the size of the operation.2Justia. Tennessee Code 55-24-101 – Chapter Definitions
What Counts as a Lemon
A vehicle is a lemon when it has a defect that “substantially impairs” its use, value, or safety. Tennessee reads that phrase to mean the vehicle is unreliable or unsafe for normal driving, or its resale value has dropped below the average for comparable vehicles. A minor rattle or a slow infotainment screen is not going to clear that bar. The defect has to affect how the car drives, how safe it is, or what it is worth. Damage from owner neglect, abuse, or unauthorized modifications does not count.2Justia. Tennessee Code 55-24-101 – Chapter Definitions
The Two Presumption Triggers
The law presumes a vehicle is a lemon once either threshold is hit during the term of protection:
- The same defect has been brought to the manufacturer or an authorized dealer at least three times and still is not fixed.
- The vehicle has been out of service for warranty repairs for a cumulative 30 or more calendar days.
Hitting one of these does not automatically win the case. It shifts the burden, so the manufacturer has to justify why the vehicle should not be replaced or refunded rather than the consumer having to prove that it should.
The Term of Protection
Everything in the lemon law runs on a clock called the term of protection. It starts when the vehicle is delivered and ends at the earlier of two events: the express warranty expires, or one year passes from the delivery date. If the manufacturer replaces the vehicle under this law, a fresh one-year term begins on the delivery of the replacement.2Justia. Tennessee Code 55-24-101 – Chapter Definitions
The defect has to be reported inside that window. The actual repair work can happen after the window closes, and it still has to be done at no cost to the consumer, as long as the complaint went in on time.3Justia. Tennessee Code 55-24-102 – Nonconforming Vehicles
Replacement or Refund
Once the manufacturer has had a reasonable number of chances and the defect is still there, the consumer chooses between two remedies.4Justia. Tennessee Code 55-24-103 – Replacement or Repair of Vehicles – Refunds – Refinancing Agreements – Defenses
Replacement
A replacement has to be a new vehicle of comparable worth: same make and model, with the options and accessories the original had. Adjustments for model-year changes are allowed. A stripped base model swapped in for a loaded original is not a comparable replacement.
Refund
A refund covers the price the consumer paid plus collateral charges, which include sales taxes, title and registration fees, manufacturer-installed accessories, credit life and disability insurance charges, and other reasonable purchase-related expenses.4Justia. Tennessee Code 55-24-103 – Replacement or Repair of Vehicles – Refunds – Refinancing Agreements – Defenses
The manufacturer is allowed to deduct a reasonable allowance for use, covering the mileage the consumer put on the vehicle before first reporting the defect and any driving done after that when the vehicle was not in the shop. The deduction is capped at half the IRS standard mileage rate for business use, plus any damage beyond normal wear and tear that was not caused by the defect. Some manufacturers try to deduct more than the cap allows, so it is worth doing the arithmetic before signing anything.4Justia. Tennessee Code 55-24-103 – Replacement or Repair of Vehicles – Refunds – Refinancing Agreements – Defenses
Financed Vehicles
If there is a loan on the vehicle, the manufacturer has to pay the lienholder in full, including accrued interest and charges, before completing the refund or exchange, unless the lienholder agrees to move the lien over to the replacement vehicle. And if the loan was through the manufacturer or a manufacturer-affiliated lender, the terms on any replacement financing cannot be more burdensome than the original.4Justia. Tennessee Code 55-24-103 – Replacement or Repair of Vehicles – Refunds – Refinancing Agreements – Defenses
Leased Vehicles
On a lease, the refund gets split. The lessee receives the deposits and lease payments already made, minus a service fee that accounts for earned interest and any insurance the lessor paid on the lessee’s behalf. The lessor is paid its actual purchase cost of the vehicle plus freight, accessories, and acquisition fees, minus what the lessee has already paid in.5Justia. Tennessee Code 55-24-104 – Leased Vehicles – Refunds
How to Bring a Claim
Document Every Repair Visit
Report the defect to the manufacturer or an authorized dealer during the term of protection, and get a written repair order every single visit. The order should describe the complaint, the work performed, and the number of days the vehicle was in the shop. Keep every repair order, invoice, and letter. A lemon law claim lives or dies on the paper trail.
Send Certified Written Notice
Before you can force a replacement or refund, you have to send a written notice to the manufacturer by certified mail describing the defect. If the manufacturer’s address is not available, delivering the notice to an authorized dealer works, because the dealer is required to forward it. After receiving that notice, the manufacturer gets one final repair attempt of no more than 10 days.
Informal Dispute Settlement
Many manufacturers run an informal dispute settlement program inside their warranties, and Tennessee recognizes qualifying programs. If your manufacturer has one, you may have to go through it before filing suit. A panel reviews whether the vehicle conforms to the warranty and can order a remedy. The manufacturer is bound by the decision. The consumer is not, so if the ruling goes against you or you are unhappy with it, you keep the right to sue.6Justia. Tennessee Code 55-24-106 – Informal Dispute Settlement Procedures
The Six-Month Deadline to Sue
Tennessee gives consumers a short window to file. A lawsuit must be brought within six months after the later of two dates: expiration of the express warranty, or one year from the vehicle’s original delivery. Time spent in an informal dispute settlement procedure pauses the clock, running from the date the dispute is submitted through the date of the decision or the manufacturer’s compliance deadline, whichever comes later.
This is where claims most often collapse. Six months goes fast, particularly when the owner spends the first several months hoping the next repair visit will finally solve the problem. Anyone getting close to that window should call an attorney rather than schedule another appointment with the service department.
Federal Backup: The Magnuson-Moss Warranty Act
The federal Magnuson-Moss Warranty Act is a separate cause of action against a manufacturer that fails to honor its written warranty. It applies to any consumer product with a written warranty, motor vehicles included, and it can reach situations the state lemon law does not. A significant advantage is cost recovery: a consumer who wins a Magnuson-Moss suit may be entitled to court costs and reasonable attorney’s fees from the manufacturer.7Federal Trade Commission. Businessperson’s Guide to Federal Warranty Law
Like the state law, Magnuson-Moss may require you to use the manufacturer’s informal dispute process first if the warranty includes one. The federal claim can run alongside a Tennessee claim, and an attorney handling a lemon case will usually weigh both.
Buying a Returned Lemon, and Used Cars Generally
Tennessee requires a title brand on any vehicle returned to the manufacturer under the lemon law, and that brand follows the car for life no matter how many owners it passes through. Dealers have to disclose the history.
The lemon law itself does not cover used vehicles. A used-car buyer who runs into serious defects may still have a Magnuson-Moss claim if a written warranty came with the car, and the implied warranty of merchantability can provide a claim against a dealer who did not disclaim it in writing at sale. Private-party sales carry almost no built-in protection. The practical safeguard is a pre-purchase inspection by an independent mechanic and a recall check through the National Highway Traffic Safety Administration before signing anything.
