About the Acura MDX
The Acura MDX launched for model year 2001 as Acura’s first SUV, built on a stretched version of the Honda Odyssey/Accord “Global mid-size” platform to seat seven. It quickly became Acura’s best-selling model and the template for every three-row luxury crossover that followed it. Since 2001 the MDX has gone through four generations:
| Generation | Years | Chassis code | Notable | Built at |
|---|---|---|---|---|
| 1st (YD1) | 2001-2006 | YD1 | 3.5L J35A V6, Acura’s first SUV | Alliston, Ontario, Canada |
| 2nd (YD2) | 2007-2013 | YD2 | 3.7L J37A V6, VCM cylinder deactivation added for 2010 | Alliston, Ontario, Canada |
| 3rd (YD3 / YD4 / YD7) | 2014-2020 | YD3 (FWD), YD4 (SH-AWD), YD7 (Sport Hybrid SH-AWD, added 2017) | 3.5L J35Y5 V6 gas; Sport Hybrid pairs a 3.0L J-series V6 with a three-motor hybrid system | East Liberty, Ohio / Lincoln, Alabama |
| 4th (YD8 / YD9 / YE1) | 2022-present | YE1 (base SH-AWD), YD8 (Type S) | New rear-biased “light-truck” platform on a longer wheelbase; Type S is the first Acura SUV with the Type S badge, a 355 hp 3.0L turbo V6 (J30AD) | East Liberty, Ohio |
That fourth-generation shift is the biggest change the nameplate has seen since launch: a longer wheelbase, a wider track, and a move toward a more rear-biased Super Handling All-Wheel Drive layout, a departure from the front-drive-based Odyssey underpinnings the first three generations shared. Type S, which arrived alongside the redesign, is the quickest and most powerful production Acura SUV built to date.
Acura MDX WMI codes (positions 1 to 3)
The first three characters of a VIN form the World Manufacturer Identifier, assigned by SAE International on behalf of ISO. We decoded real MDX VINs from every generation against NHTSA’s vPIC database to confirm these:
| WMI | Country | Plant | MDX generations built here |
|---|---|---|---|
| 2HN | Canada | Alliston, Ontario | YD1, YD2 |
| 5J8 | USA | East Liberty, Ohio / Lincoln, Alabama | YD3, YD4, YD7, YD8, YE1 |
| 5FR | USA | East Liberty, Ohio / Lincoln, Alabama | YD3, YD7 (confirmed on 2017 to 2018 examples; runs alongside 5J8 as a second WMI once one code’s serial range fills up) |
If your MDX VIN starts with anything other than the codes above, treat it as suspect. The MDX has never been built in Japan or Europe, so a VIN beginning with JH4 or WBA, for example, is not a genuine MDX regardless of what the title says. Decode the full VIN with the tool at the top of the page to confirm.
How to decode an Acura MDX VIN, position by position
Every MDX built since 2001 uses the 17-character ISO 3779 standard. The string breaks into three blocks, and each character carries specific meaning.
Positions 1 to 3: World Manufacturer Identifier
See the table above. The first character is the country of build, the second is the manufacturer, and the third encodes vehicle class. 2HN means a Canadian-built Acura; 5J8 and 5FR mean a US-built Acura SUV. The country code identifies the factory, not Acura’s headquarters in Torrance, California.
Positions 4 to 8: Vehicle Descriptor Section (VDS)
Honesty matters more than a tidy table here. On many brands position 8 is a clean single-character engine code; on the MDX it isn’t. We tested dozens of checksum-valid, NHTSA-confirmed VINs across every generation, and the character that actually separates one drivetrain from another is position 6, the third character of the YD_ or YE_ string: YD1 and YD2 are whole generations by themselves, YD3 is 3rd-gen front-wheel drive, YD4 is 3rd-gen SH-AWD, YD7 is the 3rd-gen Sport Hybrid, YD8 is the 4th-gen Type S, and YE1 is the 4th-gen base SH-AWD.
Position 8, by contrast, tracks trim and equipment package. On real decoded YD3/YD4/YD7 VINs from the same 2018 model year, the identical J35Y5 engine came back under position-8 characters corresponding to Standard, Tech, Tech Entertainment, Advance Entertainment, Elite, and SH-AWD variants. Don’t try to reverse-engineer the engine from position 8 alone; the decoder above reads the full VDS pattern against Honda’s actual build tables, which is the only reliable way to get the real answer.
Here’s what we confirmed directly, generation by generation:
| Chassis code | Years | Engine | Confirmed via |
|---|---|---|---|
| YD1 | 2001-2006 | 3.5L J35A5 SOHC V6 | 2003 MDX, VIN 2HNYD18803H500001 |
| YD2 | 2007-2013 | 3.7L J37A1 SOHC V6 | 2008 MDX, VIN 2HNYD28848H500001 |
| YD3 / YD4 | 2014-2020 | 3.5L J35Y5 V6 (direct injection) | 2018 MDX, VIN 5J8YD3H3XJL000001 |
| YD7 | 2017-2020 | 3.0L V6 (JNA2 family) plus three-motor Sport Hybrid system | 2020 MDX Sport Hybrid, VIN 5J8YD7H73LL000130 |
| YE1 | 2022-present | 3.5L J35Y5 V6 | 2023 MDX, VIN 5J8YE1H47PL004896 |
| YD8 | 2022-present | 3.0L J30AD turbocharged V6, 355 hp | 2023 MDX Type S, VIN 5J8YD8H91PL000334 |
Position 9: Check digit
The check digit is the one character in the VIN that catches typos. It’s calculated from the other 16 characters using a fixed weighting table and modulo-11 math. Mistype a single character anywhere in the VIN and the math no longer matches; any compliant decoder, every state DMV, and the NHTSA recall database will reject the entry. Every VIN cited on this page passes that check.
Position 10: Model year
The 10th character maps to model year on a 30-year cycle, the same cycle used across the entire industry:
| Char | Year | Char | Year | Char | Year |
|---|---|---|---|---|---|
| 1 | 2001 | 9 | 2009 | H | 2017 |
| 2 | 2002 | A | 2010 | J | 2018 |
| 3 | 2003 | B | 2011 | K | 2019 |
| 4 | 2004 | C | 2012 | L | 2020 |
| 5 | 2005 | D | 2013 | M | 2021 |
| 6 | 2006 | E | 2014 | N | 2022 |
| 7 | 2007 | F | 2015 | P | 2023 |
| 8 | 2008 | G | 2016 | R | 2024 |
| S | 2025 | ||||
| T | 2026 |
The letters I, O, and Q are skipped because they resemble 1 and 0. Because the MDX has run continuously since 2001, this single cycle covers every model year the nameplate has used; there’s no wraparound ambiguity to resolve the way there is on a nameplate that predates 1997.
Position 11: Assembly plant
A single character identifies the specific factory. We confirmed each of these against real, checksum-valid MDX VINs:
| Char | Plant | Generations |
|---|---|---|
| H | Alliston, Ontario, Canada | YD1, YD2 |
| L | East Liberty, Ohio | YD3, YD4, YD7, YD8, YE1 |
| B | Lincoln, Alabama | YD3, YD7 (confirmed on real 2017 to 2018 VINs) |
Positions 12 to 17: Serial number
The final six characters are the production sequence stamped on your specific MDX as it left the line. Combined with the previous 11 characters, this makes every MDX VIN globally unique.
MDX trim levels and how they appear in the VIN
An Acura MDX VIN does not spell out the trim name in plain text; trim is reconstructed from the position-8 character combined with the equipment group on the build sheet, the same way the engine confusion above gets resolved. Common North American MDX trims by generation:
- YD1 (2001-2006): Base, Touring, Touring with Navigation and Entertainment
- YD2 (2007-2013): Base, Tech, Sport (added 2010), Advance
- YD3 / YD4 (2014-2020): Standard, Tech, Advance, A-Spec (added 2017), Elite
- YD7 Sport Hybrid (2017-2020): Sport Hybrid, Sport Hybrid Advance
- YE1 / YD8 (2022-present): Base, Technology, A-Spec, Advance, Type S, Type S Advance
When you decode an MDX VIN with the tool above, the result also returns the drivetrain (FWD or SH-AWD depending on generation) and factory equipment groups, so you can match a build sheet or window sticker.
Where to find the VIN on an Acura MDX
Several locations on every MDX, plus the paperwork:
- Lower-left corner of the windshield, visible from outside the vehicle
- Driver’s side door jamb sticker (also carries tire spec and GVWR)
- Stamped on the engine bay firewall or shock tower, depending on generation
- Vehicle title, registration, insurance card, AcuraLink app on later models
The windshield and door jamb are the easiest to read on a used-vehicle lot. Check the firewall stamp if you suspect a cloned or altered VIN; it’s physically tied to the vehicle and much harder to swap than a plate or sticker.
Acura MDX recalls and safety
The MDX has been part of several notable NHTSA recall campaigns. The most significant covers 2003-2006 (YD1) models fitted with defective Takata airbag inflators: moisture intrusion could over-pressurize the front passenger inflator, risking rupture and metal fragments on deployment. Owner notifications for this MDX recall began in 2016 as part of the broader industry-wide Takata campaign.
More recently, certain 2019-2020 MDX and MDX Sport Hybrid vehicles were recalled for a fuel pump impeller that can crack and cause the engine to stall while driving, part of the wider 2.5-million-vehicle Honda/Acura fuel pump recall first issued in 2020 and expanded in 2021 and again in 2024.
To check your specific MDX:
- Decode the VIN with the tool above to confirm the exact model and year
- Cross-reference the 17-character VIN with Acura’s US recall lookup or NHTSA’s recall database
- Contact your nearest Acura authorized service center for any open campaign repair
Recall repairs are free regardless of vehicle age, mileage, or ownership history.
Frequently asked questions
How do I decode an Acura MDX VIN?
Type the 17-character VIN from the windshield, door jamb, or title into the decoder at the top of this page. Results return in under three seconds and include generation, model year, engine, trim, drivetrain, plant of origin, and any open NHTSA recalls. No sign-up.
Where is the VIN on an Acura MDX?
The two easiest spots are the lower-left corner of the windshield, read from outside the car, and the driver-side door jamb sticker. Both are required by federal labelling regulation. The engine bay firewall carries a matching stamp on most generations.
What does an MDX VIN starting with 2HN mean?
2HN is the WMI for Acura’s Alliston, Ontario plant in Canada. An MDX with a VIN starting 2HN is a first- or second-generation model (YD1 or YD2, 2001 to 2013), the only two generations built there. Every MDX from 2014 onward carries a US WMI (5J8 or 5FR) instead.
How do I tell the generation of my MDX from the VIN?
Look at position 6, the third character after YD or YE in positions 4 to 6. 1 is the 1st generation (2001-2006), 2 is the 2nd (2007-2013), 3 is 3rd-gen front-wheel drive, 4 is 3rd-gen SH-AWD, 7 is the 3rd-gen Sport Hybrid, 8 is the 4th-gen Type S, and YE1 (rather than a YD prefix) is the 4th-gen base model. The 10th character then confirms the exact model year.
Is the Acura MDX VIN decoder really free?
Yes. VinDecoderPlus decodes every Acura MDX VIN free of charge with no sign-up. The basic decode covers everything the factory stamped into the VIN. A full vehicle history report (accident records, odometer history, prior ownership, salvage status) is available as a paid upgrade if you need it.
Can an Acura MDX VIN be faked?
The 17 characters can be retyped on a counterfeit plate, but the check digit at position 9 catches most single-character changes through math, and the firewall stamp is physically tied to the original vehicle. If the windshield and door-jamb VINs match but the firewall stamp doesn’t, the vehicle may be cloned. The guide how to check if a car is stolen by VIN walks through the verification steps.
