How Long Can a Dealership Hold Your Car for Repair? (Your Legal Rights Explained)

Your car’s been at the dealership for weeks. Nobody’s calling you back. Sound familiar? You actually have more legal power here than you think. This post breaks down exactly how long a dealership can hold your car for repair, what triggers your lemon law rights, and what to do when enough is enough.

There’s No Single Federal Time Limit — But States Have You Covered

Here’s the honest answer: no single federal law says “a dealership must return your car within X days.” But that doesn’t mean dealers can hold your vehicle forever.

A well-developed system of state lemon laws and the federal Magnuson-Moss Warranty Act draws a hard legal line. Cross it, and the manufacturer faces serious liability. The most common threshold you’ll see across U.S. states is 30 cumulative days out of service — though some states set the bar even lower.

The key word there is cumulative. Days don’t have to run back-to-back. Every day your car sits at a dealership — even if it’s spread across multiple visits — counts toward the total.

How Out-of-Service Days Actually Get Counted

Most people assume the clock only starts ticking once a technician physically touches the car. That’s wrong. Under lemon law frameworks, these days all count:

• Days waiting for a technician to start diagnostics
• Days parked on the lot while waiting for manufacturer authorization
• Days spent on diagnostics where the tech claims they “couldn’t duplicate” your complaint
• Days your car sits at home because a manufacturer rep declared it unsafe to drive

There’s also a split between states on how they count:

• Calendar days (includes weekends and holidays): California, Florida, Alabama, Georgia, Louisiana, and others
• Business or working days (excludes weekends and holidays): Alaska, Colorado, Illinois, Indiana, Delaware, and others

That difference matters more than it sounds. Thirty business days is actually six weeks. Thirty calendar days is a month. Know which rule applies in your state.

State-by-State Breakdown: Out-of-Service Thresholds

The table below shows how different states handle the question of how long a dealership can hold your car for repair before lemon law protections kick in.

Does a Loaner Car Reset the Clock? It Depends on Your State

Some dealers hand you a loaner and assume that buys them unlimited time. In certain states, they’re right — but in others, it changes nothing.

In Texas, the Motor Vehicle Warranty Enforcement Act explicitly says that days you spend driving a comparable loaner vehicle don’t count toward the 30-day threshold. The dealership gets a legal safe harbor for providing substitute transportation.

In California and Louisiana, the clock runs continuously regardless of whether you have a loaner. Under California’s Song-Beverly Consumer Warranty Act, the only question is whether your specific vehicle is out of service. A loaner doesn’t change that answer.

So before you accept a rental and assume the problem is handled, check your state’s rules. A loaner might be comfort, not a legal solution.

Parts Backorders: Can the Dealer Just Wait Indefinitely?

Backordered transmission modules. Missing EV battery packs. Delayed ADAS sensors. These supply chain delays are increasingly common — and dealers frequently use them as justification for holding your car for months.

Whether that excuse holds up legally splits along state lines:

States where parts delays don’t excuse the manufacturer (California, Louisiana): The out-of-service clock keeps running no matter why the part isn’t there. California lemon law attorneys and courts take the position that manufacturers operate at their own risk if they prioritize new vehicle production over repairing existing customers’ cars.

States where parts delays can pause the clock (New York): If a dealer can prove they actively worked to source the part, those days may not count. But there’s a trade-off — New York law requires the manufacturer to extend your warranty by one day for every day your car sits waiting, so you don’t lose coverage because of their delay.

Hitting the Threshold: What the “Rebuttable Presumption” Means for You

Once your car exceeds the statutory out-of-service limit within the warranty window, something important shifts legally. You trigger what’s called a rebuttable presumption of nonconformity.

Normally, you’d have to prove the vehicle has a substantial defect that can’t be fixed. Once the presumption kicks in, the burden flips. The manufacturer now has to prove one of the following:

• The defect is minor and doesn’t actually impair safety, value, or use
• The delay was your fault — abuse, neglect, or unauthorized modifications
• The vehicle was ultimately repaired within a reasonable time given the circumstances

In states where parts delays count toward the threshold, manufacturers face an uphill battle rebutting a clear, documented out-of-service record.

What You’re Entitled to If the Dealer Goes Too Far

When the statutory limits are crossed and the manufacturer can’t rebut the presumption, the remedy under lemon law is designed to put you back where you started financially. You’re typically entitled to:

• Full purchase price including down payment and all loan or lease payments made
• Collateral charges — sales tax, registration fees, title costs
• Incidental damages — towing, diagnostics, rentals, rideshare costs tied to the defect
• Lender payoff — the manufacturer pays off your remaining auto loan directly

The manufacturer does get to subtract a mileage offset — a deduction based on how far you drove before the defect first appeared. In California, the calculation uses 120,000 miles as the vehicle’s expected lifespan. New York uses 100,000 miles.

One more thing: once a buyback is finalized, the car’s title gets permanently branded as a “Lemon Law Buyback.” That marking stays with the vehicle forever, warning every future buyer about its history.

Software Defects and EV Repairs: The New Legal Frontier

Modern cars aren’t just mechanical — they’re computers on wheels. Infotainment failures, ADAS calibration issues, and EV charging software errors now account for a growing chunk of dealership hold times.

California’s Law Revision Commission guidelines now explicitly address this. Days your car sits waiting for a software patch or manufacturer server approval count toward the 30-day out-of-service limit. The law is catching up to the technology.

Under updated California frameworks, there’s also a new pre-suit notice requirement. If you don’t send formal written notice to the manufacturer before filing a lawsuit, you can lose your right to civil penalties — even if your out-of-service days clearly exceed the threshold.

Before You Sue: The Arbitration Step

Before you file a lawsuit, many states and manufacturers require you to go through an informal arbitration process first. The BBB Auto Line is the most widely used program.

Here’s how it works:

• Fast: Decisions typically come within 40 to 60 days of filing
• Low-cost: No attorney required, no court fees
• Flexible: Hearings happen in person, by phone, or virtually
• Non-binding on you: If the arbitrator rules against you or the remedy is inadequate, you can reject the decision and go to court anyway
• Binding on both parties if you accept: Once you accept the ruling, the manufacturer must complete the buyback or replacement — usually within 45 to 90 days

Some manufacturer-specific programs have their own rules. Under the Genesis BBB Auto Line program, for example, an arbitrator can award a repurchase if the vehicle has been out of service for more than 60 days with documented parts delays expected to extend at least another 60 days.

How to Protect Yourself During a Long Repair Hold

You don’t have to sit and wait. Taking an organized, proactive approach to documenting your repair history is the single most important thing you can do. Here’s what that looks like:

Control your service records. Never leave a dealership without a physical or digital copy of the repair order. It needs to show the drop-off date, the odometer reading, and your exact complaint in your words. When you pick the car up, demand a completed invoice with the completion date, pick-up mileage, and what was actually done. New York’s DMV rules require shops to provide written estimates and return replaced parts on request — know your local rights.

Watch for complaint rewording. Dealers sometimes change the description of a recurring problem to make one continuous issue look like several separate minor ones. Read every invoice before you sign.

Keep your own out-of-service log. Dealership records can be lost or altered. Your independent log should include:

• Exact calendar dates the vehicle was in the dealer’s possession
• Names and titles of every service advisor or tech you spoke with
• Copies of all texts, emails, and voicemails about parts delays and estimated return dates
• Any documentation of manufacturer-imposed holds like corporate technical assistance reviews

Send a formal notice when you’re getting close to the threshold. Don’t rely on verbal promises from the service desk. Find the manufacturer’s address in your warranty manual and send a certified letter with return receipt. State the VIN, your full repair history, your total out-of-service days, and formally demand a final repair attempt or a repurchase.

Talk to a lemon law attorney before you assume legal help is out of reach. Both state lemon laws and the Magnuson-Moss Warranty Act include fee-shifting provisions. If you win, the manufacturer pays your attorney’s fees. Most lemon law attorneys work on contingency for this reason — meaning you pay nothing out of pocket unless you prevail.

Your car shouldn’t turn into an indefinite houseguest at the dealer. Now you know exactly when the law says enough is enough — and what to do about it.
