BMW Warranty Check by VIN — See What Coverage Is Actually Left.
A used BMW is worth a very different amount depending on whether it still has factory coverage behind it, and the listing almost never tells you. BMW of North America covers new cars and SAVs for 4 years or 50,000 miles, whichever comes first — but that clock starts on the in-service date, not the model year printed on the window sticker, and those two dates can sit more than a year apart on an inventory or demo car. This free BMW warranty check reads the VIN, decodes the model year, estimates the remaining window against BMW's published terms, and pulls NMVTIS title records for any salvage or rebuilt brand that would end coverage outright.

Quick Answer
- How do I check BMW warranty by VIN?
- Enter the 17-character VIN into the free BMW warranty check on this page. It decodes the model year and reads NMVTIS title records, then estimates what is left of BMW's 4-year / 50,000-mile New Vehicle Limited Warranty. For the exact in-service date, any BMW Center can look the VIN up in BMW's own system free of charge.
- How long is the BMW factory warranty?
- BMW of North America covers new passenger cars and SAVs for 4 years or 50,000 miles, whichever comes first. Rust perforation runs 12 years with unlimited mileage, and on i-series and plug-in models the high-voltage lithium-ion battery is covered 8 years or 100,000 miles from the in-service date.
- Does BMW warranty transfer to the second owner?
- Yes — the balance of the New Vehicle Limited Warranty follows the VIN, not the buyer, so a used BMW still inside 4 years and 50,000 miles arrives with coverage attached and no transfer fee. What does not transfer is coverage on a VIN carrying a salvage or rebuilt brand, which is why the warranty check reads NMVTIS at the same time.
Three things happen between your VIN and the answer
A BMW warranty check looks like one box and one button. Underneath, it is a decode, a records read, and a date calculation — and the third one is where most people's mental arithmetic goes wrong.
- 1The VIN gets decodedCharacters one through three identify BMW and the plant country; the tenth character is the model-year code. That gives the tool a model year and a body type to work from, which is what determines which of BMW's coverage tiers apply to the car in front of you.
- 2NMVTIS gets readThe same VIN goes to the National Motor Vehicle Title Information System, the federal title database, looking for salvage, junk, rebuilt, and flood brands. A brand here matters more than any date arithmetic, because it ends factory coverage regardless of how much time is left on the clock.
- 3The remaining window gets estimatedBMW's 4-year / 50,000-mile term is measured from the in-service date. The decoded model year is a close proxy but not the real thing, so the result is an estimate you take to a BMW Center for confirmation — not a number to negotiate against on its own.
What BMW's Factory Coverage Actually Includes
BMW does not sell one warranty. It publishes several, each with its own clock, and a used-BMW buyer usually cares about three of them. These are BMW of North America's own published terms for US-market cars, quoted rather than paraphrased.
4yr/50kNew Vehicle / SAV Limited Warranty — BMW's core coverage for defects in materials and workmanship on passenger cars and light trucks, running 4 years or 50,000 miles from the in-service date, whichever occurs first. This is the number people mean when they say "still under warranty."12yr/∞Rust Perforation Limited Warranty — 12 years with unlimited mileage, covering body panels that rust through from the inside out. Surface corrosion and stone-chip rust are not the same thing and are not covered here, which is a common source of denied claims on older cars.8yr/100kHigh-voltage battery — on i-series and plug-in hybrid BMWs, BMW of North America warrants the high-voltage lithium-ion battery assembly against defects in materials or workmanship for 8 years or 100,000 miles from the in-service date, whichever occurs first.1yr/∞BMW Certified Pre-Owned Limited Warranty — 1 year with unlimited miles, and critically it begins after the 4-year / 50,000-mile New Vehicle Limited Warranty expires rather than running alongside it. That sequencing is what makes CPO worth paying for on a car near the end of its factory window.>300 / <60kCPO eligibility — a BMW must show more than 300 miles and fewer than 60,000 miles on the odometer to be certified. A car advertised as "certified" with 70,000 miles on it is being described loosely, and the warranty check is how you find that out before the paperwork.
Note what is missing from that list: scheduled maintenance. BMW Ultimate Care covers oil services, filters, and other routine items on newer cars, and it is a maintenance program rather than a warranty — different term, different rules, and it does not pay for a failed component. Ultimate Care terms have changed across model years, so confirm the specific car's coverage with a BMW Center rather than assuming the current program applies to a used one.
The In-Service Date Is the Only Date That Matters
Almost every wrong answer about BMW warranty coverage comes from starting the clock in the wrong place. The warranty does not run from the model year, the build date, or the date the current seller bought the car. It runs from the in-service date — the day BMW recorded the vehicle as delivered to its first retail owner, or the day it was first put into service as a loaner or demonstrator.
On a car that sold off the lot the month it arrived, model year and in-service date land close enough that the difference does not matter. On an inventory unit that sat two model years, a dealer demo, or a loaner that ran up 6,000 miles before anyone bought it, the gap is large and it runs in the buyer's favour: a 2023 BMW first placed in service in 2024 keeps its warranty into 2028, not 2027. This is why the estimate on this page is explicitly an estimate. The VIN gives us a model year; only BMW's system gives the actual date.
The practical move is to use the free check to find out whether the car is anywhere near the boundary, then have a BMW Center read the VIN if it is. Any BMW Center can look up warranty status by VIN, it costs nothing, and it takes a phone call. A five-second free check that says "this car is two years past the window" saves you the call entirely; one that says "this is within a few months of the line" is exactly when the call is worth making.
Two dates, one that counts
- Model year
VIN character 10 - In-service date
BMW records only - Warranty clock starts
In-service date
The decoded model year is a proxy. On inventory cars, demos, and loaners the real in-service date can sit a year or more later — always in the buyer's favour.

Certified Pre-Owned — What the BMW CPO Warranty Adds
BMW's Certified Pre-Owned Limited Warranty runs 1 year with unlimited miles, and the detail that matters is when it starts: after the 4-year / 50,000-mile New Vehicle Limited Warranty has expired, not concurrently with it. So CPO does not double your coverage on a two-year-old car — it extends the tail on a car that is running out.
That changes how you value the badge. On a 2-year-old BMW with 20,000 miles, CPO is buying you a year of coverage that begins two years from now, and the price premium should be judged against that. On a 4-year-old BMW just past 50,000 miles, CPO is the difference between coverage and no coverage today, and it is worth considerably more. Running the warranty check first tells you which of those two situations you are actually in.
Eligibility is worth checking independently too. BMW requires a vehicle to have more than 300 miles and fewer than 60,000 miles on the odometer to be certified. "Certified" is used loosely in a lot of listings — sometimes it means a third-party inspection or a dealer's own in-house plan rather than BMW's program. If the odometer is above 60,000 miles, whatever is being sold is not a BMW CPO warranty, and the paperwork should say whose warranty it actually is.
Reading a CPO listing honestly
- Odometer above 60,000 miles → it cannot be BMW CPO
- Ask whose warranty: BMW's, the dealer's, or a third party's
- CPO starts when the 4yr/50k factory window ends, not today
- Get the coverage document in writing before the deposit
- Confirm no salvage or rebuilt brand sits on the VIN
Check the VIN before you talk price:
What Ends BMW Coverage Early
Time and mileage are the ordinary ways a warranty runs out. These are the ways it stops early — and the first one is the reason this tool reads title records rather than just doing date arithmetic.
A salvage, junk, or rebuilt title brand
When an insurer declares a BMW a total loss, the state records a salvage brand against the VIN, and factory coverage ends. Repairing the car and passing a state inspection produces a rebuilt brand, which does not bring the warranty back. A rebuilt BMW can look immaculate and drive normally and still have no factory coverage behind it at all — which is precisely why the brand check runs alongside the date estimate here.
Damage from modification or unauthorized repair
BMW's limited warranty covers defects in materials and workmanship. It does not cover damage caused by something else — and aftermarket tunes, forced-induction changes, suspension modifications, and repairs done outside the authorized network all create the argument that the failure was caused rather than inherent. The warranty is not automatically "voided" wholesale, but the specific claim gets denied, which amounts to the same thing when the bill arrives.
Neglected service and high-voltage tampering
Missed oil services and skipped scheduled maintenance give BMW grounds to deny a related claim, so service records matter as much as the warranty dates on a used car. On i-series and plug-in models, third-party work on the high-voltage battery pack is the equivalent risk — it puts the 8-year / 100,000-mile battery coverage in question, and that is the single most expensive component on the car.
Buying used? Pair this with the general warranty check for cross-make context and a focused salvage title check if anything in the title chain looks unusual. A brand two owners back still ends coverage today.
Where to Find the VIN on a BMW
Every BMW carries its VIN in several places at once, and that redundancy is useful for more than convenience — if the numbers disagree with each other, you have found a much bigger problem than a warranty question.
The quickest read is through the windshield at the lower driver-side corner, from outside the car. The driver-side door jamb sticker is the second, and it also carries the manufacture date, which is worth photographing because it tells you how long the car plausibly sat before its in-service date. The title, the registration, and the insurance card all print the VIN, and the My BMW app shows it on the vehicle profile.
Copy it from the door jamb label if you can. The dashboard plate sits under glass in direct sun for years and gets hard to read; the jamb label is printed, protected, and less likely to be misread. Then compare it against the title before you do anything else — a mismatch between the glass, the jamb, and the paperwork is the classic signature of a cloned VIN, and no warranty estimate means anything on a car whose identity is wrong.
Where the BMW VIN lives
- Lower driver-side windshield, read from outside
- Driver-side door jamb label (also shows manufacture date)
- Vehicle title and state registration
- My BMW app — vehicle profile
- Insurance ID card
Any one of them works for the check. Use two of them to confirm the car is what the paperwork says it is.
Where These Numbers Come From
Every coverage figure on this page is quoted from BMW of North America's published US warranty terms rather than summarised from a third-party article, because warranty terms change by model year and secondhand summaries go stale quietly. The 4-year / 50,000-mile New Vehicle Limited Warranty, the 12-year unlimited-mileage rust perforation coverage, the 8-year / 100,000-mile high-voltage battery term, and the 1-year unlimited-mileage CPO warranty with its 60,000-mile eligibility ceiling are all BMW's own published figures.
The title-brand side comes from NMVTIS, the federal vehicle title database operated by the US Department of Justice, which aggregates title and brand records from participating state motor vehicle agencies, insurance carriers, and salvage operators. Federal emissions coverage — separate from anything BMW chooses to offer, and required of every manufacturer selling in the US — is set by the Clean Air Act and administered by the EPA.
None of that replaces the one authoritative answer for a specific car, which lives in BMW's own system and is keyed to the in-service date. Use this page to decide whether that call is worth making, then make it.

BMW Warranty Check — Common Questions
What used-BMW buyers ask once they realise the model year is not the warranty start date.
How do I check BMW warranty by VIN?+
Enter the 17-character VIN into the free BMW warranty check form on this page. The tool decodes the model year from the tenth VIN character, applies BMW of North America's published 4-year / 50,000-mile New Vehicle Limited Warranty term, and reads NMVTIS for any salvage, junk, or rebuilt title brand that would end factory coverage. The result is an estimate, because BMW measures the warranty from the in-service date rather than the model year, and only BMW holds that date. For a definitive answer on a specific car, any BMW Center can look the VIN up in BMW's own system at no cost.
How long is the BMW factory warranty?+
BMW of North America covers new passenger cars and SAVs under the New Vehicle Limited Warranty for 4 years or 50,000 miles, whichever occurs first, against defects in materials and workmanship. Separately, the Rust Perforation Limited Warranty runs 12 years with unlimited mileage, and on i-series and plug-in hybrid models the high-voltage lithium-ion battery assembly is warranted for 8 years or 100,000 miles from the in-service date. Those are three different clocks on the same car, so a BMW can be out of its basic warranty while still inside its battery or corrosion coverage.
Does the BMW warranty transfer to a second owner?+
Yes. The balance of BMW's New Vehicle Limited Warranty follows the vehicle rather than the original buyer, so a used BMW still within 4 years and 50,000 miles of its in-service date arrives with the remaining coverage attached, at no transfer fee. The exception is a VIN carrying a salvage, junk, or rebuilt title brand — those end factory coverage permanently, and no subsequent sale restores it. That is why a warranty check should always be run together with a title-brand check rather than on its own.
When does the BMW warranty clock actually start?+
On the in-service date — the day BMW recorded the vehicle as delivered to its first retail owner, or first placed into service as a demonstrator or loaner. It does not start at the model year, the build date, or the date the current seller acquired the car. On a vehicle that sold quickly the difference is small, but on inventory units, demos, and loaners the in-service date can sit a year or more after the model year, which extends real coverage in the buyer's favour. This is the single most common source of wrong answers about BMW warranty status.
What is the BMW Certified Pre-Owned warranty?+
BMW's Certified Pre-Owned Limited Warranty provides 1 year of coverage with unlimited miles, and it begins after the 4-year / 50,000-mile New Vehicle Limited Warranty expires rather than running alongside it. To be eligible for certification, a BMW must show more than 300 miles and fewer than 60,000 miles on the odometer. If a listing describes a car with higher mileage as certified, it is not BMW's program being offered — it may be a dealer's own plan or a third-party contract, and the coverage document will say which.
Does a salvage title void a BMW warranty?+
Yes. A salvage brand is recorded when an insurer declares the vehicle a total loss, and it ends BMW's factory warranty coverage. Repairing the car and passing a state re-inspection produces a rebuilt brand, which does not restore the original warranty. This holds regardless of how well the repair was done or how the car presents in person, and it applies to a brand recorded several owners ago just as much as a recent one. The free check on this page reads NMVTIS for those brands at the same time it estimates the remaining coverage window.
Is BMW Ultimate Care the same as the warranty?+
No, and conflating the two is a common and expensive mistake. BMW Ultimate Care is a scheduled maintenance program covering routine service items such as oil changes and filters. The New Vehicle Limited Warranty is defect coverage — it pays when a component fails because of a manufacturing or materials fault. A car can have maintenance coverage remaining and no defect coverage, or the reverse. Ultimate Care terms have also varied across model years, so confirm what applies to the specific used car with a BMW Center rather than assuming the current program carries over.
Is the high-voltage battery covered separately on an i-series BMW?+
Yes. BMW of North America warrants the high-voltage lithium-ion battery assembly against defects in materials or workmanship for 8 years or 100,000 miles from the vehicle's in-service date, whichever occurs first — a longer term than the 4-year / 50,000-mile basic coverage on the rest of the car. On a used i-series or plug-in hybrid BMW this is usually the coverage worth checking most carefully, since the pack is the highest-value single component. Third-party work on the pack puts that coverage at risk, so service history on the high-voltage system deserves the same scrutiny as the title.
