2008 Acura RDX: what breaks, and at what mileage
What breaks on the 2008 Acura RDX
On the 2008 Acura RDX, the failure owners report most often is airbag inflator rupture, with 8 reports on file. Across every failure mode on this year, half the dated reports were filed before 60,000 miles. Overall it scores 59 out of 100, elevated risk for a 2008.
Elevated risk for a 2008 — 345th riskiest of the 356 2008 vehicles we can rate. 39 owner reports; fleet size estimated from this year's own recall paperwork.
The failures owners actually file about
Owners have reported 16 named failure modes on the 2008 Acura RDX, and the three most-reported carry 33% of everything filed, which is an unusually even spread for one model year.
Airbag inflator rupture leads with 8 reports and about 0.2 per 1,000 vehicles.
Seat belt or retractor failure follows with 3 reports, median 60,000 miles.
Airbag warning light or occupant sensor fault follows with 2 reports, median 115,000 miles.
By system, the reports fall mostly into airbag (14), wheels (3) and electrical (2).
When these failures get reported
24 of the reports on the 2008 Acura RDX came with an odometer reading, and half of those were filed before 60,000 miles.
Cumulatively, 21% by 50,000 miles and 88% by 100,000 miles of the dated reports had been filed.
The busiest stretch is between 60,000 and 70,000 miles, which alone holds 25% of the dated reports.
13% of the dated reports were filed below 36,000 miles.

Severity, and what it costs
Across the named modes, 3 mention a crash. Those are the words owners used in their own complaints, and NHTSA does not verify them, but they are the closest thing in this data to a measure of what a failure actually did.
The average severity weight across every report on this year is 4.21, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel, and a figure this high means the reports are dominated by failures with safety consequences rather than annoyances. The weighting is set out in full on the methodology page.
What the top failures cost to put right, as editorial estimates for an independent US shop rather than figures from NHTSA: airbag inflator rupture at $0–$0, seat belt or retractor failure at $200–$900, airbag warning light or occupant sensor fault at $300–$1,600 and other electrical problem at $250–$2,000. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
8% of the reports on this year sit in the engine, transmission, drivetrain or cooling systems — the four where a repair bill is usually four figures.

Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.
How often, against how many were built
Scaled by an estimate of how many of these cars exist, the 2008 Acura RDX draws about 1.1 per 1,000 vehicles, which puts it in the 73rd percentile of complaint rates among 2008 vehicles we can rate.
That denominator is the weakest number on the page and it is fair to say so plainly. Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound.
The working figure is 36,003 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2008 vehicles, which is what the risk score uses, is far more robust than the rate itself.
What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The odometer reading is the one the owner gave.
Airbag inflator rupture
Takata recall was supposedly completed,by dealer awhile ago. Now getting a 'check airbag system' message and 'side airbag off. Understand there are a fair number of complaints re this and wondering if should be covered because safety issue. Someone on a blog said their honda element similar issue was covered because safety issue. As it is about $1000 repair hoping you can tell me it should be covered.
Seat belt or retractor failure
Tl* the contact owns a 2008 acura rdx. The contact stated that while exiting the vehicle, the driver's side seat belt failed to retract properly after being unbuckled. In addition, the speedometer failed to properly display an accurate speed rate. The vehicle was taken to the dealer for diagnosis but they were unable to duplicate the problem. The manufacturer was notified. The approximate failure mileage was 60,000. Updated 10/29/13*lj the consumer stated the dealer and manufacturer were unwilling to test the vehicle. Some advised only acura could test/repair the vehicle. The consumer also was advised the tools needed where too expensive for the vehicle to be tested for the odometer failure. *js

Airbag warning light or occupant sensor fault
Takata recall my 2008 acura rdx was a part of the takata air bag inflator recall and was apparently repaired on january 20th of 2017. However, the SRS light came on in my 2008 acura rdx on 7/27/2018 when my vehicle was stationary as I started the vehicle. I took my vehicle to the acura dealership in wexford, pa on 8/4/18, and they informed me that my passenger side airbag inflator was open causing the SRS system to default (code #32-21). Meaning that my airbag safety system will not function properly, due to the faulty airbag inflator. This is a major safety concern, and I would like this to be resolved by a follow up recall for the passenger side air bag inflators for all cars affected by the takata airbag inflator recall. To my understanding, when my drivers side airbag inflator was replaced/repaired back in 2017, they replaced the passenger side airbag inflator as well. So I would just like to make sure that I can get this faulty system replaced through a recall of both airbag inflators for the 2008 acura rdx (both meaning: driver's and passenger's side air bag inflators). Please see attached invoice. Thank you for your time.
Recalls on the 2008 model year
NHTSA has issued 3 recall campaigns covering the 2008 Acura RDX, affecting an estimated 48,591 vehicles. A recall is a different kind of evidence from a complaint: it is the regulator and the manufacturer agreeing that something has to be fixed, and the fix is free for as long as the car exists.
The campaigns cover air bags:frontal:driver side:inflator module and equipment:other:labels. Whether the work was actually done on the car in front of you is a question only the VIN can answer, and the manufacturer or NHTSA will answer it free.
One caution about reading these together: a recall usually raises the complaint count for the same part, because owners who read about it go and file. The mileages stay informative; the counts get noisy.

How it ranks in the 2008 field
The score at the top of the page, placed among its peers. The zones are the same thresholds the scorer applies, read out of the scorer itself, so the picture and the band word cannot disagree.
Scores are ranked within the model year, never across years, because an older car has had longer to accumulate reports.
- Left fewer and less serious reports
- Right more, or worse
- Marker this vehicle
Where 2008 sits in the model line
Elevated risk for a 2008 — 345th riskiest of the 356 2008 vehicles we can rate. Every score on this site is a rank inside its own model year, which is what makes a 2004 and a 2019 comparable at all.
Across the 19 model years of this car that carry enough reports to score, 2008 comes out best at 59 and 2017 worst at 82, with 2008 itself at 59.
No other year of this model scores meaningfully better than 2008, so if this generation is what you want, the year is not the lever.
Within the 2007–2015 generation specifically, 2008 is the strongest year at 59 and 2013 the weakest at 67.
Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.
Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.
Within the 2007-2015 generation, 2008 Acura RDX scores best at 59 and 2013 Acura RDX worst at 67.
The limits of complaint data
39 owner reports; fleet size estimated from this year's own recall paperwork. Every count on this page is therefore a floor: it is the number of owners who went to the trouble of filing with a federal agency, which is a small and self-selected fraction of the owners who had the fault.
Of those 39 reports, 24 carried an odometer reading, so the mileages here describe 62% of the sample rather than all of it. Owners also round: readings pile up on multiples of ten thousand, which is why this site publishes "about 90,000 miles" and not "91,438".
The failure modes are assigned by software reading the owner's own words, which is accurate in bulk and wrong in individual cases. A mode with a handful of reports may contain a misfiled one.
And nothing here predicts what one car will do. These are other people's complaints, filed years apart, on cars maintained by strangers. Read the page as a map of where this model year has previously gone wrong, then have the specific car in front of you inspected.
Questions this page answers
What are the most common problems with the 2008 Acura RDX?
The most-reported failures are airbag inflator rupture (8 reports, median 130,000 miles), seat belt or retractor failure (3 reports, median 60,000 miles) and airbag warning light or occupant sensor fault (2 reports, median 115,000 miles). Counts come from owner complaints filed with NHTSA, which are voluntary, so they show what owners bothered to report rather than every fault that occurred.
Is the 2008 Acura RDX reliable?
It scores 59 out of 100 on our risk index, which is elevated — 345th riskiest of the 356 2008 vehicles we can rate. The score is a comparison against other 2008 vehicles, not a prediction about any individual car, and it is built from complaint rates, severity and how early failures appear.
Which year of the Acura RDX is best?
Within the 2007–2015 generation, 2008 scores best at 59 out of 100 and 2013 worst at 67. Same body, same engines, different luck.
Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
