What stands out
Of the 7 model years of Acura MDX we track for suspension problems, this one carries the most owner complaints on file — 12.
No new NHTSA suspension complaint has been filed on this vehicle in over 11 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering suspension on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

full bulletin at NHTSA ↗Customer letter - owner notification for the front and rear active dampers may leak. While leaks on the rear active suspension are visible, the front active dampers are mounted in an inverted position and the leak is not visible on the exterior of the damper. If an excessive amount of damper oil has leaked, the active dampers may make a clunk or a bang sound when driving on rough roads or over speed bumps.

The failure pattern owners describe
The 2007 MDX suspension fails consistently and expensively across front and rear. Front and rear struts leak, crack, or lose damping force between 50,000 and 125,000 miles—some failures occur within two years of purchase. Replacement runs $1,000–$1,500 per strut or damper, plus labor. Sport suspension models with shock mounts report rattling that lasts months before catastrophic failure; the shocks themselves cost $1,000 each and are dealer-only.
The Active Damper System (ADS) on equipped vehicles appears linked to premature strut failure. Acura Canada extended warranty coverage for ADS-related damper replacement through end of 2016 and honored claims. Acura USA has refused to acknowledge a defect or offer similar extended coverage, instead classifying failures as wear-and-tear even on low-mileage examples.
Clunking over bumps and rough roads is endemic, sometimes accompanied by excessive tire wear despite tie rods and bushings testing normal. One owner reports front wheel bearing noise (moaning or droning). Dealers often took months to diagnose strut problems that independent shops identified in minutes, raising questions about whether dealers were documenting and concealing known issues.
Failure modes owners describe
Front and rear struts/dampers failing prematurely
Struts and shock dampers on both front and rear leak fluid, lose structural integrity, or break. The active damper system (ADS) in equipped vehicles appears to be a contributing factor. Owners report needing replacement around 50,000–125,000 miles. Replacement cost per strut or damper is $1,000–$1,500 per unit plus labor.
When: 50,000–125,000 miles; some failures reported within 2 years of ownership
Symptoms owners cite: Clunking or banging noise over bumps and rough roads; Rattling sounds from underneath vehicle; Leaking fluid from rear dampers or shocks; Loss of ride control quality
Repairs/costs cited: Strut/damper replacement $1,000–$1,500 per unit plus labor. Acura Canada issued extended ADS warranty through end of 2016 for some affected vehicles; Acura USA did not honor similar coverage. Dealers often deny warranty claims citing wear-and-tear despite low mileage.
Recalls/TSBs owners mention: Acura Canada extended warranty for ADS-related strut failures through end of 2016 and authorized replacement/reimbursement. Acura USA denied defect acknowledgment and warranty coverage, claiming wear-and-tear despite low-mileage complaints. Some owners report lack of recall notification despite November 2016 notification sent to some owners.
Shock mount rattling and failure (sport suspension models)
Shock mounts on sport suspension-equipped MDX vehicles rattle for months before failing. Owners discovered this is a known issue in MDX forums but dealers initially failed to diagnose it. Cost per shock is $1,000, dealer-only parts.
When: Rattling precedes failure; mileage not specified in narratives
Symptoms owners cite: Rattling from shock mounts that persists for months; Vehicle unsafe before repair
Repairs/costs cited: Shock replacement $1,000 per unit, dealer-only parts. Most owners report limited or no dealer participation in repair cost.
Multiple clunking/suspension noise from undercarriage
Clunking sounds occur every bump or on rough surfaces. Owners report tie rod bushings and other suspension components check out okay, but excessive tire wear occurs in short timeframe, suggesting alignment or suspension geometry issues despite normal component wear.
When: Ongoing for one year reported; occurs on rough roads and over speed bumps
Symptoms owners cite: Clunking on every bump and rough surfaces; Excessive tire wear in short period; Rattle from undercarriage components
Repairs/costs cited: Tie rods and bushings inspected normal; underlying cause not definitively identified by owners or dealers in narratives
Front wheel bearing noise or vibration
Front right wheel bearing produces moaning, droning, or humming noise and vibration while driving.
When: Mileage not specified
Symptoms owners cite: Moaning, droning, or humming noise from front right side; Vibration from front right wheel area

The electronic suspension on our 07 mdx is an extra paid option, we did not buy new but we still paid for that option as it increases value new or used... The rear dampers in ours are leaking and for a set to replace costs at least $1000 in parts and then you have to pay labor. This is a premium brand, but it is not an exotic... Not sure why an Acura ads suspension part that probably costs them…
Takata recall I have a complaint on Acura mdx 2007 sport entertainment on replacing struts. The value on replacing them is ridiculously expensive and I have read some many complaints about the same issue that they need to be replace every 50,000 miles could this be a recall because replacing them every 50,000 miles at a high value is to expensive.
I have a 2007 mdx with about 125,000 miles on it. I received a notification dared november 2016 from Acura that the front and rear active dampers might be bad. The vehicle makes clunking and banging sounds when I drive on rough roads or go over speed bumps and I believe that the dampers are bad. I requested a review, case 05228502 and was immediately rejected by an Acura employee in…

Common questions
How serious is the suspension problem on the 2007 Acura MDX?
It's a documented issue but not catastrophic. 12 complaints have been filed. Repairs average $900 and most owners catch it before it causes a breakdown.
At what mileage does the suspension typically fail?
Across the 10 complaints that reported odometer mileage, most suspension failures cluster between 70,000 and 115,700 miles, with the median around 97,000. A quarter of owners report trouble before 70,000; a quarter make it past 115,700. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $900 for suspension repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to suspension?
No active recalls currently cover suspension issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
