The 2008 Acura MDX has no open NHTSA recalls. Owners report 8 recurring issue clusters, led by “Hood flutter and vibration at highway speed.” Acura's Maintenance Minder calculates oil life from real engine conditions and shows service codes instead of fixed mileages — code A or B (oil / oil + inspection) plus sub-codes for items like tire rotation (1), air filters (2), or transmission fluid (3). Follow the codes, not the calendar. One interval you should never stretch: most Acura 3.5L V6 engines (MDX, TL) use a timing belt with a roughly 105,000-mile / 7-year replacement — a snapped belt on this interference engine means bent valves. SH-AWD models add a rear-differential fluid service that's essential for the torque-vectoring unit.
No open recalls on file. NHTSA lists no unrepaired safety recalls for this year, make and model. A recall can be issued at any time, and a specific car can still have one open — check yours by VIN at nhtsa.gov/recalls.

“HOOD ON 2008 ACURA MDX FLUTTERS AT HIGHWAY SPEEDS. *TR”
“AT HIGHER SPEEDS THE HOOD FLUTTERS UP AND DOWN, EVEN THOUGH THE HOOD IS LATCHED DOWN. THE DEALER SAID IT WAS COMMON AND WANTED TO CHARGE ME TO FIX IT... *TR”
“I PURCHASED THIS CAR USED IN OCTOBER 2014. EVER SINCE I HAD THE CAR I NOTICE THAT THE HOOD STARTS VIBRATING AS IF IT IS GOING TO OPEN”
VISIBILITY
4 NHTSA complaints · 2010-09 → 2018-02
“THE SUNROOF EXPLODED WHILE ON THE HIGHWAY”
“TL* THE CONTACT OWNS A 2008 ACURA MDX. WHILE DRIVING APPROXIMATELY 65 MPH, THE SUN ROOF EXPLODED WITHOUT WARNING. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 100,000”
“WE WERE DRIVING OUR 2008 ACURA MDX ON THE OPEN HIGHWAY AT 60 MPH WITH THE MOONROOF IN THE TILT POSITION. NO OTHER VEHICLES WERE CLOSE. THE MOONROOF GLASS SUDDENLY EXPLODED, SENDING GLASS BOTH OUTSIDE AND INSIDE THE VEHICLE”
SUSPENSION
6 NHTSA complaints · 2009-11 → 2016-06
“THE ADS SENSOR HAS GONE BAD ON MY 2008 MDX. SOME HAVE BEEN RECALLED IN COLORADO BECAUSE SALT PUT ON THE ROADS FOR SNOW CONDITIONS HAS CARRIED THEM”
“I HAVE A MDX WITH SPORT SUSPENSION. I RECENTLY VISITED MY MECHANIC TO DISCOVER THAT BOTH OF MY REAR SHOCKS ARE BLOWN”
“IN JANUARY 2013 MY ADS LIGHT IN MY MDX WENT ON. WE RESEARCHED AND FOUND THAT ACURA HAD SENT A SERVICE REQUEST TO CERTAIN VIN NUMBERS FOR THIS VERY PROBLEM. THE PROBLEM IS IN THE DESIGN OF THE ADS SYSTEM FOR THE MDX'S WAS POOR AND IT ALLOWED SALT AND MOISTURE”
ELECTRICAL SYSTEM
5 NHTSA complaints · 2015-01 → 2019-01
“*****ACURA MDX 2008 BATTERY IS DRAINING AND CAR WILL NOT START DUE TO HFL UNIT.********”
“THE HANDS FREE LINK CONSTANTLY DRAINS THE BATTERY, EVEN WHEN THE VEHICLE IS NOT IN USE. I HAVE REPLACED 3 BATTERIES. THIS ISSUE LEAVES YOU STRANDED AND THE REPAIR COST BY DEALERS ARE RIDICULOUS WHEN THIS IS A WIDE SPREAD ISSUE”
“BATTERY WAS REPLACED IN FEBRUARY 2017 (ABOUT 7 MONTHS AGO). TODAY, EVERYTHING ELECTRICAL JUST DIED WHILE I WAS DRIVING”
SERVICE BRAKES, HYDRAULIC

Critical for safety and preventing major damage
Change when the Maintenance Minder reaches 15% oil life or shows code A/B — typically every 7,500-10,000 miles with 0W-20 synthetic. Short-trip city driving triggers the code sooner; that's the algorithm doing its job.
Estimated cost — typical U.S. ranges
Dealer
~$120–$160
Shop
~$85–$115
DIY
~$25–$55
Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
J-series V6: replace the timing belt around 105,000 miles or 7 years (Maintenance Minder sub-code 4). It's an interference engine — a failed belt destroys valves. Replace the water pump and tensioner in the same job. (2022+ MDX 3.5L remains belt-driven; the Integra's turbo four is chain-driven.)
Estimated cost — typical U.S. ranges
Dealer
~$935–$1175
Shop
~$655–$825
DIY
Pro only
On interference engines, a snapped belt destroys valves. Worth doing on schedule. Bundle water pump + tensioner — labor is already there.
Rotate when sub-code 1 appears — roughly every 7,500 miles. SH-AWD models: keep tread depths matched across all four corners.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Often free at the shop where you bought the tires — worth asking before paying.
Inspect pads, rotors, and fluid level with every A/B service. Type S models with Brembo front calipers: pads wear faster and cost more — budget ahead.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
Replace every 3 years regardless of mileage — Honda/Acura schedules this on time because the fluid absorbs moisture.
Estimated cost — typical U.S. ranges
Dealer
~$180–$200
Shop
~$125–$140
DIY
~$10–$25
DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.
Keeps your vehicle running smoothly and efficiently
Replace ATF when sub-code 3 appears — commonly every 30,000-60,000 miles depending on duty. Use Honda/Acura ATF only (DW-1, or the 10-speed's specified fluid); aftermarket 'universal' ATF causes shudder in these gearboxes.
Estimated cost — typical U.S. ranges
Dealer
~$330–$500
Shop
~$235–$355
DIY
~$60–$180
Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.
SH-AWD (MDX, TLX, RDX): replace the rear differential fluid roughly every 30,000 miles (sub-code 6) — the torque-vectoring clutch packs run in this fluid, and whining or binding in tight turns is the classic overdue symptom.
Estimated cost — typical U.S. ranges
Dealer
~$150–$195
Shop
~$105–$135
DIY
~$20–$50
Iridium plugs around 100,000 miles on most models. Turbocharged Integra/ADX engines: check the manual — forced induction typically shortens the interval.
Estimated cost — typical U.S. ranges
Dealer
~$285–$390
Shop
~$200–$275
DIY
~$25–$100
Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.
Replace with sub-code 2, roughly every 30,000 miles — sooner in dusty conditions.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
5-minute job on most cars; the airbox lid usually has clips, no tools needed.
Extends the life of your vehicle and improves comfort
Replace with sub-code 2 alongside the engine air filter. Behind the glovebox — an easy DIY on most Acuras.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.
Honda/Acura Type 2 coolant: first change around 10 years / 100,000 miles, then every 5 years / 50,000. Use the blue Type 2 coolant only.
Estimated cost — typical U.S. ranges
Dealer
~$285–$330
Shop
~$200–$235
DIY
~$25–$60
Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.

occupant deaths
Crash years covered: 1990–2024 This model year first appears in 2008 crashes. Older models have had more years on the road to appear in these crashes, so a higher count here does not by itself mean a vehicle is less safe.
FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number
FARS 2024 data is an annual report file. NHTSA revises these records when the final file is published, so this count can change.
Every vehicle has exactly one driver seat, so driver deaths line up fairly when you compare one model to another. Occupant deaths include passengers, so a three row SUV can show a higher number than a two seat car simply because it carries more people.
Both figures are plain counts, not rates. A rate would need to know how many of each vehicle are on the road, and that registration data is not public, so we do not publish rates or scores of any kind.
IIHS publishes driver death rates using this same driver only idea, paired with a registered vehicle years denominator we do not have. Their rates and these counts answer different questions, so do not read either number here as a safety rating.
Owner-reported problem signals
Separate from the federal fatality data above: complaints owners filed with NHTSA about this year and model. These are reports of problems, unverified, and are counted here only as signals.
