Mileage when owners reported a problem with the 2009 RDX
Too few complaints on the 2009 RDX list a mileage to say when owners reported problems: 4 of its 15 complaints list a mileage (50 to 79,000 miles), and a median is given here only with 10 or more.
These mileages say when owners reported a problem, not when a 2009 RDX wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.
Every model year together: Half of the 554 NHTSA owner complaints on the Acura RDX that list mileage came after 24,000 miles (NHTSA complaints file of November 11, 2026). How many miles will an Acura RDX last? →
Is the 2009 RDX a good year?
Complaint counts cannot say whether the 2009 is a good or a bad RDX: they rise with how many were sold and how long they have been on the road. They show how the 2009 compares with the other model years in NHTSA's file.
With 15 complaints, the 2009 ranks 17th of the 19 Acura RDX model years from 2007 to 2025 with 10 or more complaints, counting from the most, tied with 2012. The most: the 2019 (442). The fewest: the 2024 (12).
Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.
| Model year | Owner complaints | Listing mileage | Median mileage |
|---|---|---|---|
| 2007 RDX | 53 | 33 | 68,057 |
| 2008 RDX | 33 | 19 | 60,000 |
| 2009 (this page) | 15 | 4 | Under 10 mileages |
| 2010 RDX | 22 | 9 | Under 10 mileages |
| 2011 RDX | 16 | 6 | Under 10 mileages |
| 2012 RDX | 15 | 8 | Under 10 mileages |

| 2020 RDX | 351 | 84 | 6,200 |
| 2021 RDX | 118 | 13 | 30,000 |
| 2022 RDX | 31 | 5 | Under 10 mileages |
| 2023 RDX | 24 | 4 | Under 10 mileages |
| 2024 RDX | 12 | 2 | Under 10 mileages |
| 2025 RDX | 31 | 4 | Under 10 mileages |
The linked 2015–2022 pages show NHTSA's September 15, 2026 collection, so their counts can differ from this table's.

2009 Acura RDX recalls
NHTSA's recall files of November 11, 2026 list 2 recall campaigns that name the 2009 Acura RDX. A campaign covers a production range, not every vehicle of the model year: check the VIN with NHTSA's free recall lookup.
What these figures can and cannot tell you
- Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
- The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
- They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2009 RDX lasts.
- A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2009 RDX.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 11 of the 15 complaints on the 2009 Acura RDX give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- NHTSA name counted: RDX. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only this one.
- Recall-file name matched: RDX.
