Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering body 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.
Dealer Message - American Honda Motor Co., Inc. (AHM) is investigating certain 2014-2017 MDXs with a complaint of the automatic tailgate inop. The failure modes include the tailgate opening under power but immediately closing (reversing) on its own or the tailgate opening under power partially before stopping, requiring manual operation to fully open. To better understand the cause of this condition, AHM would like to collect specific information from the vehicle prior to you attempting a repair of any kind.

The failure pattern owners describe
The dominant complaint is roof paint peeling on 2016 MDX vehicles with White Pearl or White Diamond Pearl paint (code NH-603P). Owners report paint delamination starting as early as three months into ownership through seven years after purchase, with one instance at 130,000 miles. Paint separates in layers, exposing bare metal and creating corrosion and roadway debris hazards. Some owners who paid $2,000–$2,400 for repainting report the defect recurring afterward.
Acura issued Service Bulletin 19-029 in August 2019 extending warranty to eight years on affected vehicles, but manufacturer denies claims for vehicles outside the specified VIN range—even when the vehicle year, paint code, and failure characteristics match the bulletin exactly. Owners report widespread complaints across online forums with many VINs unaffected by the warranty extension despite experiencing identical failures.
A separate complaint describes sunroof glass breaking spontaneously while driving at 50 mph on a highway, with the casing collapsing inward and causing vehicle vibration.
One complaint involves spare tire sidewalls wearing through at multiple locations by 20,000 miles, with the dealer unable to determine the cause.
Failure modes owners describe
Roof paint delamination and peeling
Factory-applied clear-coat and base-coat separation on roof panels, particularly affecting White Pearl (NH-603P) and White Diamond Pearl paint. Large sections of paint peel away, exposing bare metal and creating corrosion risk. Paint failure occurs in layers with loss of adhesion between coating layers.
When: Typically 3–7+ years after purchase; one complaint at ~130,000 miles in 2023
Symptoms owners cite: Paint peeling or chipping on roof, particularly in front of sunroof; Paint missing in patches around sunroof and side edges of roof; Large sections of rigid paint fragments detaching; Bare metal exposure on roof panel; Paint peeling reoccurring even after initial repair
Repairs/costs cited: Dealers quoted $2,000–$2,400 for full roof repainting; some owners report peeling recurs after repair
Recalls/TSBs owners mention: Acura Service Bulletin 19-029 (dated 08/29/2019) issued for paint delamination on certain VINs with warranty extension to 8 years from vehicle in-service date. However, manufacturer denies coverage for vehicles with matching year and paint code but outside VIN range specified in bulletin; Acura Care and Honda Care deny claims based on VIN exclusion despite identical failure characteristics; extended warranty may have expired by the time owner reports the issue
Sunroof glass breakage and casing collapse
Sunroof glass spontaneously breaks while driving; sunroof casing caves inward. Failure occurred at highway speed (50 mph) with sudden loud pop and vehicle vibration.
When: While driving on highway; specific mileage not stated
Symptoms owners cite: Sudden loud pop sound from roof while driving; Vehicle shaking and vibration; Sunroof glass broken; Entire sunroof casing caving in
Spare tire sidewall wear-through
Sidewalls of spare tire stored underneath vehicle wearing through at multiple locations, creating potential failure risk.
When: By 20,000 miles
Symptoms owners cite: Sidewalls of spare tire wearing through at three different locations
Repairs/costs cited: Dealer advised owner not to worry; cause of failure not determined

What owners are reporting 1 most recent
Our 2016 MDX starting peeling paint off the roof. Acura said they extended the warranty for this known defect for an 8 year period. Since this problem just happened we are outside the 8 year extension. The internet is full of similar stories of people like us who have the paint peeling after the bogus 8 year extension. Acura said they aren't responsible. This isn't right.

Common questions
How serious is the body problem on the 2016 Acura MDX?
It's a documented issue but not catastrophic. 17 complaints have been filed. Repairs average $1,500 and most owners catch it before it causes a breakdown.
At what mileage does the body typically fail?
Based on the 17 complaints filed, body issues most often appear around 22,500 miles. Some report problems earlier; some make it well past 150,000 with no symptoms. Maintenance habits matter — vehicles that received timely fluid services and were not regularly overworked tend to last longer.
What does it cost to fix?
Independent shops typically charge around $1,500 for body 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 body?
No active recalls currently cover body 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.
