NJ Lemon Law Days Out of Service: The 20-Day Rule
Your car has been sitting at the dealer for what feels like forever. First it was a week. Then another visit, and another. Now you’re wondering whether all that time in the shop counts for something under the NJ lemon law, and whether there’s a magic number of days.
There is. New Jersey counts days out of service, and the number is 20. That’s lower than many people expect. But the way those days get counted is where most of the confusion lives.
This post explains how the 20-day rule works for new cars, the 45-day rule for motor homes, how days from different problems add up, and how the separate used car law counts time a car spends waiting for repairs. For the bigger picture, our complete guide to New Jersey lemon law covers the whole statute.
What Does “Days Out of Service” Mean in New Jersey?
New Jersey’s new car lemon law gives consumers three ways to show a manufacturer had a fair shot at fixing a defect and failed. One is repeat repairs. Another is a serious safety defect that survives even one repair. Both of those are covered in our breakdown of what qualifies as a lemon for new cars in NJ. The third is time, and that’s the one this post is about.
Under N.J.S.A. 56:12-33, the law presumes a manufacturer couldn’t fix the car in a reasonable time if the car has been out of service by reason of repair for a cumulative total of 20 or more calendar days since original delivery, and a defect still exists. Those days have to fall inside the term of protection, which is the first 24,000 miles or two years after delivery, whichever comes first.
20 calendar days
The cumulative days-out-of-service threshold for a new car under New Jersey’s lemon law. For a motor home, it’s 45 calendar days.
A “presumption” is a legal shortcut. It means the law starts from the assumption that the manufacturer had enough chances. The manufacturer can still argue otherwise, but the burden shifts in the consumer’s favor.
How the Regulations Define a Day
The statute says “calendar days” and stops there. The state’s lemon law regulations at N.J.A.C. 13:45A-26 fill in more detail. They define “out of service” as the number of days the car is on the premises of a repair facility for the purpose of repairing one or more defects.
Calendar days means weekends and holidays count. If your car sits at the dealer from a Friday to the following Monday, that’s four calendar days on the lot, even though only two were business days.
How the 20 Days Add Up Under the New Car Law
The key word in the statute is “cumulative.” The 20 days don’t have to be one long stretch. They can come from several shorter visits that add up over the term of protection.
Days From Different Problems Can Count Together
This is the part that surprises people. The repeat-repair path generally looks at the same defect coming back again and again. The days-out-of-service path is different. The regulations describe it as time out of service by reason of repair for one or more defects.
So a week for an engine problem and a week for an electrical problem can both go into the same count. What the law still requires is that at least one defect continues to exist after all that time. A car that was in the shop for 25 days but is now fully fixed is a different situation.
Days That Don’t Count
The regulations carve out one big exception. Delays caused by the consumer, such as being slow to pick up the car after the dealer says it’s ready, are not counted as days out of service.
Routine maintenance also sits outside the count, because the definition is tied to repairing a defect. An oil change or tire rotation isn’t a repair of a nonconformity, so that time generally wouldn’t qualify.
Watch the pickup gap. If the dealer calls to say the car is ready and it sits there three more days, those three days are generally treated as consumer delay, not days out of service.
Motor Homes Get 45 Days
For a motor home, the threshold jumps to 45 or more calendar days. The statute also has a travel rule. If a motor home owner keeps traveling and gets the same problem looked at by a second authorized shop instead of waiting for the first repair to finish, the law treats that as one repair attempt, not two.
The statute and regulations also say that, in certain motor home situations, a visit to a shop the manufacturer hasn’t authorized doesn’t count as a repair attempt. That can matter for owners who break down far from a dealer that services their rig.
Example: How a Mercer County Driver Reaches 20 Days
Say Mei buys a new Kia Telluride from a dealer on Route 1 in Lawrenceville. Two months in, the SUV loses power and drops into limp mode on I-295. She drops it off on a Thursday, and the dealer keeps it for 8 days waiting on a sensor.
Five months later, the climate control and front defroster quit in January. That visit takes 6 days. Then the power loss comes back, and the SUV sits for another 9 days. On that last visit, the dealer calls on a Tuesday to say it’s ready, but Mei can’t get there until Friday.
Here’s how the count generally works:
- First power loss visit: 8 days
- Climate control and defroster visit: 6 days
- Second power loss visit: 9 days, minus the 3 days the SUV waited for pickup, for 6 counted days
That’s 20 counted days, all inside the first two years and under 24,000 miles. The defroster days add to the power loss days because the regulations count time spent repairing one or more defects. If the power loss still happens after that third visit, Mei’s situation would generally fit the 20-day presumption.
Notice how close it was. If Mei had picked up the SUV a day later, or if the dealer’s paperwork showed a later drop-off date, the total could have landed at 19. That’s why the dates on the paperwork matter so much. Mei is made up, and every real count depends on the actual repair records.
Why the Drop-Off Date on the Repair Order Matters
Days out of service are proven with paper, not memory. The New Jersey regulations require the dealer to hand over an itemized, legible statement of repair every time the car comes back during the term of protection. That statement has to show the date and odometer reading when the car was dropped off, and the date and odometer reading when it was made available again.
Those two dates are what the count is built on. A lemon law application to the state includes copies of these repair statements. If a repair order lists the wrong drop-off date, or if the car was left overnight and the order wasn’t opened until the next afternoon, the count can come up short.
Say Victor leaves his car in the dealer’s night drop box in Union on a Sunday evening. The service writer doesn’t open the repair order until Tuesday. On paper, the car went in on Tuesday, even though it’s been sitting on the lot since Sunday. Those two days can disappear from the record unless something else shows when the car really arrived.
Key takeaway: Under the new car regulations, the repair statement must show the drop-off date, the pickup-ready date, and the odometer at each point. Those dates are usually the main evidence of how many days a car was out of service.
What Happens After 20 Days in the Shop in NJ
Hitting 20 days doesn’t automatically turn a car into a lemon. The presumption only applies once the manufacturer has received written notice by certified mail, return receipt requested, inside the term of protection. The manufacturer then gets one final chance to fix the defect within 10 calendar days of receiving it. Reaching 20 days is one of the events that allows that notice to go out.
From there, the claim moves through the application and hearing steps covered in our guide to the NJ lemon law hearing process. The days also connect to money. Rental car costs for the time the car was out of service because of a defect can be part of what a consumer recovers, as our post on how a NJ lemon law buyback is calculated explains.
One narrow rule can stretch the count. If repairs weren’t available because of a war, strike, fire, flood, or other natural disaster, that time is added to both the 20-day period and the two year term. Our post on the NJ lemon law time frame covers that extension and the rest of the timing rules.
How the NJ Used Car Lemon Law Counts Days
Used cars run under a completely separate law with its own rules. It applies to qualifying used cars bought from a dealer and ties protection to a short dealer warranty. Our post on whether used cars actually qualify walks through who’s covered.
The used car law also uses a 20-day number, but it measures something slightly different. Under N.J.S.A. 56:8-71, the dealer is presumed to have had a reasonable chance to fix the car if it was out of service for a cumulative total of 20 or more days during the warranty period while waiting for the dealer to begin or complete repair.
That “begin or complete” language matters. Time spent waiting for the dealer to even start working on the car counts, not just time spent with a mechanic under the hood. And under the used car regulations at N.J.A.C. 13:45A-26F, that same waiting time also extends the warranty itself, which our post on the 30, 60, and 90 day used car warranty explains.
Example: Bianca’s Used CR-V in Elizabeth
Say Bianca buys a 2021 Honda CR-V with 45,000 miles from a dealer in Elizabeth for $19,000, which gives her a 60 day warranty. Three weeks in, the all wheel drive starts whining and shuddering. The dealer keeps the SUV 12 days before a part even arrives, then sends it home.
A month later the same noise is back. This time the CR-V waits 9 more days for the dealer to finish the repair. That’s 21 days of waiting on the same covered drivetrain problem inside the warranty, which crosses the used car law’s 20-day line. Bianca is made up, and every real situation turns on the dealer’s dates and records.
New car law counts days the car is at a repair facility being repaired. Used car law counts days the car is waiting for the dealer to begin or complete repairs, and that waiting time also extends the warranty itself.
How New Jersey’s 20-Day Rule Differs From Federal Law
The 20-day count comes from state law, not federal law. The Magnuson-Moss Warranty Act covers written warranties nationwide, but it doesn’t set a specific number of days out of service.
Common Questions About Days Out of Service in NJ
What if my car is out of service for 20 days in NJ?
For a new car, 20 or more cumulative calendar days out of service for repair, inside the term of protection, with a defect that still exists, is one of the three triggers for the lemon law presumption. The certified mail notice and the manufacturer’s 10-day final repair chance still come into play before the presumption applies.
Do the 20 days have to be in a row?
No. Both the new car and used car laws use a cumulative total. Three visits of 7 days each add up to 21 days.
Do weekends and holidays count toward the 20 days?
For a new car, yes. The statute counts calendar days, so a car that sits at the dealer over a holiday weekend racks up every one of those days.
My new car keeps going to the shop for different problems. Does that count?
Under the new car regulations, days out of service are counted for repairing one or more defects, so time spent on different problems can add together. The repeat-repair trigger is different, since it looks at the same defect coming back.
Do days count if the dealer is just waiting on parts?
For a new car, the definition looks at days the car is on the premises of a repair facility for the purpose of repair, and neither the statute nor the regulations carve out parts delays. For a used car, the law expressly counts time spent waiting for the dealer to begin or complete repair.
The Bottom Line on NJ Days Out of Service
New Jersey counts 20 cumulative calendar days out of service for a new car, or 45 for a motor home, and days from different defects can add up. The used car law counts 20 days of waiting for the dealer to begin or finish repairs, and that waiting also stretches the warranty. In both cases, the dates on the repair paperwork are what the count is built on.
