A new luxury or exotic car that won’t stay fixed: your warranty rights, the lemon law, and the paper trail

Updated October 25, 2026 · Written by the Only for the Wealthy editors · General information, not legal or financial advice

A new grand tourer or supercar should be the most rewarding thing in the garage. When it keeps returning to the service bay with the same fault, the law gives its owner real leverage, but mostly to the owner who knows the rules and kept the paperwork. Here is what federal warranty law and Illinois’s lemon law actually say, where each one stops, and how the discerning owner builds a file a manufacturer has to take seriously.

We don’t sell vehicles. Only for the Wealthy is a publisher. We don’t sell, lease, broker, consign, or arrange the sale or lease of any vehicle, and we don’t act as an agent for buyers, lessees, dealers, or manufacturers (see 625 ILCS 5/5-101). This is general information about U.S. federal law and one state statute, Illinois’s, not legal advice. Every state’s lemon law is different; before you make a claim, speak with a consumer-law attorney licensed where you bought the car.

Why this matters now

More recalls mean more appointments at the dealer. BizzyCar’s Q3 2026 recall report, built on NHTSA recall data, counts 32.1 million vehicles recalled through the end of September 2026. That already exceeds the full-year totals for 2022, 2024, and 2025; of the five years the report tracks, only 2023, at 33.6 million, was higher [1]. In the third quarter, 76.7% of recalled vehicles needed a dealer visit rather than an over-the-air update [1]. A lemon-law claim turns on a narrower question, whether a defect covered by the warranty substantially impairs the car’s use, market value, or safety and survives repeated repair [14]. Either way, every visit creates a record, and the record is what decides warranty disputes.

1. Four layers of protection

Layer	Where it comes from	What it gives you
The manufacturer’s written warranty	Magnuson-Moss Warranty Act (15 U.S.C. 2301 and following) and FTC rules	Terms you can read before you buy, a “full” or “limited” label, and a ban on brand-name service conditions [4][5][10]
Implied warranties	State law, protected by Magnuson-Moss	Can’t be disclaimed by a company that gives you a written warranty or sells you a service contract at the sale or within 90 days [7]
State lemon law (Illinois shown here)	815 ILCS 380, the New Vehicle Buyer Protection Act	Replacement or refund after a reasonable number of repair attempts in the first year or 12,000 miles [14]
Safety recalls	49 U.S.C. 30120	A free remedy for a recalled defect: repair, replacement, or refund, at the manufacturer’s choice [15]

2. Your federal warranty rights

Cars are covered. The FTC’s interpretations say products such as automobiles, used for both personal and commercial purposes, are “consumer products” under the Act. It looks at the type of product, not at how one buyer uses it, and resolves any doubt in favor of coverage [9]. A later owner who receives the car while the warranty is still running is also a “consumer” [3].
Read it before you buy. For products costing more than $15, the seller must make the warranty text available before the sale, either displayed near the product or provided on request. A manufacturer may instead post the terms on its website, as long as it tells you where to find them and sends a free paper copy on request [10][4]. Ask for the full text, not the brochure summary.
What the warranty can be required to say. The Act lets the FTC require plain-language disclosure of who the warrantor is, what is covered, what the warrantor will do and at whose expense, what you must do, the exclusions, the step-by-step claim procedure, any informal dispute program, and your legal remedies [4].
“Full” or “limited”. A written warranty must be conspicuously labeled either a “full (statement of duration)” warranty or a “limited” warranty [5]. A full warranty must meet the federal minimum standards: fix the defect within a reasonable time without charge, put no limit on how long implied warranties last, show any exclusion of consequential damages conspicuously on its face, and, if the defect survives a reasonable number of repair attempts, let you choose a refund or a free replacement [6]. A warranty that falls short of those standards must be called limited [5]. The label on your car’s warranty tells you which promises you actually hold.
Implied warranties stay. A company that gives you a written warranty, or sells you a service contract at the sale or within 90 days, can’t disclaim implied warranties. It may limit their length to that of a reasonable written warranty, but only in clear, prominent language, and a disclaimer that breaks these rules has no effect [7].

3. The tie-in ban: your aftermarket parts, your choice of shop

No warrantor may make its warranty depend on your using a brand-name part or service unless that part or service is provided free under the warranty, or the FTC has granted a waiver [4]. The FTC’s interpretations give the example of a clause that says the warranty “is void if service is performed by anyone other than an authorized” dealer and that all parts must be genuine, and call it prohibited where the service or parts aren’t covered free [9].

The FTC tells car owners plainly: it’s illegal for a dealer to deny warranty coverage because you had routine maintenance or repairs done somewhere else, and your warranty stays in effect if you use aftermarket or recycled parts [2].
The limit: if a defective aftermarket part, or a badly installed one, damages a covered part, the manufacturer can deny coverage for that damage. The FTC says the manufacturer or dealer must prove the part caused it [2]. The warranty may also expressly exclude damage caused by “unauthorized” parts or service [9].
The FTC enforces this. In July 2024 its staff warned eight companies (makers of air purifiers, a treadmill, and computer hardware, not cars) about tying warranties to branded parts and about “warranty void if removed” stickers [12]. In October 2022 it approved final orders against Harley-Davidson and two other manufacturers over warranties that claimed independent repair or third-party parts would void coverage; the orders require warranty language saying that independent repair shops or third-party parts won’t void coverage [13].

For the tuned car. An exhaust, wheels, or a software tune doesn’t void the whole federal warranty, but a failure the manufacturer can show the modification caused isn’t covered [2][9]. Under the Illinois lemon law, abuse, neglect, or unauthorized modifications that caused the failure are a defense for the manufacturer, and if someone else modified the part that failed, that party is the one liable [14]. If you plan to modify a new car, keep the original parts and every receipt, and consider waiting until the first-year window has passed.

4. The manufacturer’s dispute program

A car warranty may route complaints to an informal dispute program before you can sue. The federal rules for those programs are worth knowing [11]:

If the warranty requires you to use the program first, it must say so on its face, with the program’s name and address or a free phone number [11]. If the program complies with the FTC rules and the warranty requires it, you must use it before suing under the Act (class actions follow a separate rule) [8].
The program can’t charge you a fee [11].
It must decide within 40 days of being notified, with two exceptions: delay caused by your not supplying basic details, and an extra 7 days if you never tried to resolve it with the manufacturer directly [11]. Write to the manufacturer first and you avoid the extra week.
Its decisions aren’t legally binding on anyone, but the manufacturer must act in good faith, and the decision can be used as evidence in court [11][8]. You can get copies of all its records about your dispute at reasonable cost [11].
Illinois adds its own step: before using the lemon-law remedies you must first use the manufacturer’s program if it substantially conforms to the FTC rules and you were given written notice of it. If you are unhappy with the result you can still sue, and the deadline is extended by the days your case was pending [14].

5. The Illinois lemon law, line by line

Who is protected. A “consumer” is an individual who buys a new vehicle, or leases one for at least a year, primarily for personal, household, or family purposes (certain fire departments are also covered) [14]. If the car is bought or titled through a company, or used mainly for business, read that definition with your attorney before relying on the Act; the federal law tests the type of product instead [9].
Which vehicles. Passenger cars, second-division vehicles under 8,000 pounds, and recreational vehicles, with exceptions for some camping and travel trailers [14].
Who answers. The “seller” includes the manufacturer, its agent or distributor, and its authorized dealer; for a leased car, the dealer that leased it; and for a modified vehicle, the company that modified it [14].
The window. One year or 12,000 miles from delivery, whichever comes first [14].
The presumption. Within that window, the law presumes a reasonable number of repair attempts if the same defect has been repaired 4 or more times and still exists, or if the car has been out of service for repairs for a total of 30 or more business days [14].
The letter that unlocks it. The presumption doesn’t apply unless the manufacturer has received prior direct written notification from you, or on your behalf, and had a chance to fix the defect [14]. A conversation with the service advisor is not written notice to the manufacturer.
The remedy. The manufacturer must either provide a new vehicle of the same model line if available, otherwise a comparable one, or take the car back and refund the full purchase price or lease cost, including collateral charges, less a reasonable allowance for your use [14]. Collateral charges don’t include the taxes you paid on the original purchase; the selling dealer may file a claim for a credit for those taxes instead [14]. The use allowance covers wear before you first reported the defect and during later periods when the car wasn’t in for repair [14]. The refund goes to you and to any lender, according to each party’s interest [14]. For a lease, “lease cost” includes deposits, fees, taxes, down payments, and periodic payments [14].
Deadlines and trade-offs. You must file suit within 18 months of original delivery [14]. If you choose to proceed and settle under the Act, you give up a separate claim under the Uniform Commercial Code [14], so take advice before you choose.
Your copy of the rules. The seller must hand you a written statement of these rights and presumptions when the car is delivered [14]. File it with the purchase contract.
Outside Illinois. Other states set their own windows and thresholds. The FTC points car owners to their state attorney general when a dealer or contract company won’t resolve a problem [2].

6. If you go to court under federal law

A consumer harmed by a breach of a written warranty, an implied warranty, or a service contract may sue in state court, or in federal court if the claims in the suit total at least $50,000 [8].
The manufacturer must first get a reasonable opportunity to fix the failure [8].
A consumer who wins may be awarded costs and attorneys’ fees based on actual time spent, unless the court finds that inappropriate [8]. When you consult an attorney, ask how fees would be handled.

7. Recalls: free, and on a clock

When a safety recall is required, the manufacturer must remedy the defect without charge, by repairing the car, replacing it with an identical or reasonably equivalent one, or refunding the price less depreciation, as it chooses [15].
If a recall repair isn’t done adequately within 60 days of presenting the car, that is prima facie evidence of failure to repair within a reasonable time, and the manufacturer must then replace the car or refund it [15].
The free remedy doesn’t apply to a vehicle the first purchaser bought more than 15 calendar years before the recall notice [15], which matters for modern classics.
A dealer holding a new car covered by a recall notice may sell or lease it only after the defect is remedied before delivery [15]. On delivery day, check the VIN on NHTSA’s recall lookup [16] and ask for the completed recall work on the repair order.

8. Service contracts, the “extended warranty”

A service contract isn’t a warranty under federal law, because you buy it separately [2]. An agreement that costs extra or is signed after the purchase is a service contract, and some are sold and regulated under state law as insurance [9].
The FTC’s advice: compare it with the factory warranty first, because a contract that starts before the factory warranty expires probably won’t help. Find out who the administrator is, whether parts are paid with a depreciation factor, whether teardown labor is covered, whether labor is capped, whether you need pre-approval, which maintenance it requires, and whether you can transfer it [2].
Buying one from the seller at the sale or within 90 days also keeps your implied warranties from being disclaimed [7].
“Your warranty is expiring” calls, texts, and letters, with phrases like “Final Warranty Notice”, are usually from companies not working with your dealer or manufacturer, the FTC says [2]. Don’t give them payment details. Report them to your state attorney general and at ReportFraud.ftc.gov [2][17].

9. The owner’s file: a checklist

Before you sign, ask for the full warranty text and note whether it’s labeled full or limited [10][5].
At delivery, keep the dealer’s written lemon-law statement [14] and confirm there are no open recalls on the VIN [16].
At every service visit, get a dated repair order that records your complaint in your own words, the mileage in and out, and the dates the car was out of service. The Illinois presumption counts repairs and business days [14].
Keep every maintenance receipt, wherever the work was done [2].
The second time the same fault returns, write directly to the manufacturer at the address in the warranty booklet, and keep proof of delivery. The Illinois presumption requires direct written notice [14].
If your warranty requires the dispute program, file promptly and note the 40-day clock [11].
Put two dates in the calendar: the end of the first year or 12,000 miles, and 18 months from delivery [14].
Before you accept a buyback or replacement offer, or choose which law to proceed under, talk to a consumer-law attorney [8][14].
Never pay an unsolicited “warranty expiring” caller [2].
