Frequently Asked Questions about Used Acura MDX in Westmont, IL
What MDX generations are available used?
Used MDX market splits across two main generations. The 4th generation (2022 and later) is the current platform - V6 plus 10-speed automatic, SH-AWD across most trims, Type S variant available. The 3rd generation (2014-2020) preceded it - 3.5L V6 with 9-speed automatic in later years (6-speed earlier), SH-AWD available throughout. There is no 2021 MDX in volume - the 4th gen launched as a 2022 model. Older 2nd gen MDX (2007-2013) appears occasionally but is less common.
Which generation should I look at?
Depends on budget and priorities. 4th gen MDX (2022+) is more refined, more powerful, has updated tech and Type S option, but commands higher used pricing - typically $40K-$60K for clean units with reasonable miles. 3rd gen MDX (2014-2020) offers most of the practical capability at substantially lower used pricing - typically $18K-$35K - with a deeper supply across model years, mileage ranges, and trim levels.
Is the 9-speed transmission a concern on 3rd gen MDX?
Worth knowing about. The 9-speed automatic introduced on later 3rd gen MDX had documented shift quality concerns in some early model years (2016-2017 in particular). Software updates during ownership addressed many issues, and many 9-speed MDX units run fine for high mileage. On used inspection, transmission shift behavior should be verified during a thorough test drive and any service history including transmission programming or hardware updates should be reviewed.
Does SH-AWD reliability hold up over time?
Generally yes. SH-AWD on used MDX units typically holds up well with normal maintenance - rear differential fluid service per Acura schedule, proper tire matching across all four corners (mismatched tire wear can stress the system), and inspection of front transfer case at higher mileage. Repair costs on SH-AWD components when issues do occur can be significant; this is one reason CPO certification matters more on AWD units than FWD.
Is used MDX Type S available?
Type S launched with the 4th generation as a 2022 model, so used Type S inventory only spans 2022, 2023, 2024, and 2025 model years. Used Type S supply is thinner than standard MDX - many Type S buyers keep their vehicles. Pricing on used Type S typically sits in the $55K-$70K range depending on year, mileage, and trim package. CPO certification on used Type S is available when units meet program criteria.

The Used MDX Market at McGrath Acura of Westmont
The MDX has been Acura's flagship three-row SUV since 2001, which means the used market spans multiple generations and a wide range of price tiers. For McGrath Acura of Westmont in Westmont, used MDX is consistently one of the most active categories in our used inventory - reflecting the strong demand for three-row family SUVs across DuPage County and the broader Chicagoland market. Buyers searching used MDX typically fall into two camps: budget-conscious families wanting capable three-row capability under $30K (3rd gen territory) and luxury-focused buyers wanting the current 4th gen platform at substantial discount versus new.
Pricing across the used MDX market reflects this split. 3rd generation units (2014-2020) typically run $15K on higher-mileage older examples up to $35K on low-mileage final-year units. 4th generation units (2022+) typically run $40K on higher-mileage 2022 units up to $60K+ on near-new 2024-2025 units with low miles and full equipment. Type S used pricing sits at the top of the range. For DuPage County buyers across Westmont, Hinsdale, Naperville, Oak Brook, Downers Grove, and the broader area, the used MDX market delivers genuine choice across budget tiers.
- Used MDX market spans two main current generations
- 3rd gen (2014-2020): $15K-$35K depending on year and miles
- 4th gen (2022+): $40K-$60K+ depending on year and equipment

For shoppers cross-shopping size down to compact luxury SUV, our used RDX inventory covers that segment. For new MDX comparison, our new MDX inventory walks through current model availability.
3rd Generation MDX (2014-2020) - What to Look For
The 3rd generation MDX (2014-2020) is the deepest used supply tier and where most of the value pricing lives. The platform shares architecture with the Honda Pilot of the same era and benefits from that platform's mechanical maturity. Powertrain across the run was the 3.5L V6 - normally aspirated, well-proven, with reasonable fuel economy for the segment. Transmission progression: 6-speed automatic on 2014-2015 units, 9-speed automatic introduced on 2016+ units. The 9-speed had documented shift quality concerns in early model years that improved through software updates.
Key inspection areas on 3rd gen used MDX include transmission shift quality (especially on 2016-2017 units), SH-AWD operation if equipped, suspension condition (particularly bushings and shocks at higher mileage), VTEC system operation on the V6, and timing belt service history (the 3.5L V6 uses a timing belt with replacement interval at 100,000-105,000 miles). Service records matter more on 3rd gen than 4th gen given the older fleet age. Vehicles with documented Acura dealer maintenance typically command modest price premium and provide better confidence in long-term ownership.
- 3.5L V6 normally aspirated across the generation
- 6-speed (2014-2015) or 9-speed (2016+) automatic
- 9-speed shift concerns mostly resolved by software updates
- Timing belt service interval 100,000-105,000 miles
- Service record continuity matters at this age
Our Acura-certified service department handles pre-purchase inspection on 3rd gen MDX including timing belt evaluation, transmission programming verification, and SH-AWD service status check.
4th Generation MDX (2022+) - What to Look For
The 4th generation MDX (2022+) launched on a fully redesigned platform with significant updates throughout. Powertrain on standard trims is the 3.5L V6 (290 hp - similar to 3rd gen but with calibration updates) paired with a 10-speed automatic - replacing the 9-speed and addressing the transmission concerns from the prior generation. SH-AWD updates, new chassis tuning, redesigned interior with True Touchpad infotainment, and the addition of the Type S variant all distinguish the 4th gen from its predecessor.
Key inspection areas on 4th gen used MDX include AcuraWatch sensor calibration (especially on units with any front-end repair history), 10-speed automatic shift quality (no widespread concerns reported but worth verifying), SH-AWD system operation, panoramic roof seal condition, and infotainment software version. Earlier 4th gen units (2022) have had software updates available; service records should reflect any campaign updates applied. Cosmetic condition matters at 4th gen pricing - most buyers want clean examples since the price premium versus 3rd gen reflects newer condition expectations.
- 3.5L V6 standard, 10-speed automatic across the generation
- 3.0L turbo V6 on Type S (355 hp, adaptive air suspension)
- SH-AWD on most trims and standard on all Type S
- True Touchpad infotainment with software update progression
- Service campaign updates worth verifying on early 2022 units
For shoppers wanting Acura CPO coverage on 4th gen MDX, our Acura CPO inventory includes available CPO units with the 24-month / 100,000-mile certified limited warranty and powertrain warranty extension.
Used MDX Type S Considerations
Used MDX Type S deserves separate treatment. Allocation has been tight since launch, demand stays high, and most owners hold their vehicles - meaning used Type S supply is thinner than other 4th gen MDX trims. The 3.0L turbocharged V6 (355 hp) and adaptive air suspension are the key differentiators that buyers seek and that command premium pricing in the used market. Pricing typically sits within $5K-$10K of equivalent new Type S, depending on year and mileage.
Key inspection areas on used Type S include adaptive air suspension operation (air suspension components can be expensive to repair if leaks or compressor failures develop), Brembo front brake pad and rotor wear (Type S brakes wear faster than standard MDX brakes due to the more aggressive driving most owners do), turbocharger condition and oil consumption pattern, transmission service history, and any signs of track or autocross use. CPO certification on used Type S adds particular value given the cost of potential repairs on the specialized hardware - the warranty extension covers components where individual repair costs can exceed the CPO premium.
- Used Type S supply thin - most owners hold their vehicles
- Pricing within $5K-$10K of new equivalent Type S
- Adaptive air suspension - inspect for leaks and compressor health
- Brembo brakes wear faster than standard MDX brakes
- CPO valuable on Type S given specialized hardware repair costs
