What are some common MDX problems?

Before every vehicle purchases, I extensively browse the subreddits of the models I'm considering to research common problems before making a purchasing decision.

What's ... different ... about this subreddit is I don't see many posts of owners having problems, outside of a few related to higher milage wear and tear. Perhaps this car is largely problem free, but I have a hard time believing there aren't a few trouble spots to watch out for.

What are some of the common problems with this vehicle. I'm specifically looking for a type-s, and I usually buy lease turn in's.

2026 MDX A-Spec - Trailer Hitch

I am looking at the Acura website and confused at what the $1501 trailer hitch option includes. It seems like its just a drawbar, pin and clip for $1501. Everything else, looks to be additional.


Trailer Hitch $1,501*

When the need arises, put your MDX to work by adding the Trailer Hitch with accessory Trailer Hitch Ball.

Receiver-style hitch accommodates a variety of trailer coupler designs  

Trailer Hitch Kit includes draw bar, retaining pin, and clip

Wiring harness with 7-pin round-style connector available separately

Towing over 3,500 lbs will require a Trailer Hitch ATF Cooler Kit which will allow towing up to 5,000 lbs
1 7/8-in or 2-in balls available separately

Our first Acura!

After almost a year of researching (and reading everything in this forum) different SUV'S and watching prices the stars aligned and we got our first Acura. It's a '22 MDX A-spec - CPO. It looks brand new. It is a one owner and was traded into the dealership that the original owner bought it from. I am absolutely in love!! I knew I wanted red and a Tech but this one fell into our lap and we couldn't say no. The salesman was fantastic and it was a super easy process. ♥️

Sorry for the bad pictures, I am a horrible photographer.

2026 Acura MDX Type S B&O system replacement/upgrade?

Love my new type S, but absolutely hate the B&O system. Bummer the ELS is gone. It’s great for some I understand, but it hurts my ears, even at low volume. I don’t know if it’s a frequency thing, faulty speakers, or just from the lack of adjustments. Even with the crappy circle adjustment, you can never seem to remove the bass and treble. After short stints, my ears are fatigued and there seems to be a slight shrill in the sound. Maybe it’s just because it’s so amplified? IDK not an expert at all with sound. But I do know that the Honda Pilot Bose system I had prior was way better for my ears.

Has anyone successfully upgraded the stock B&O for model year 25/26 to better speakers, or modified with software, the current system, to make it better? Can it be addressed by a car audio shop?

Ridiculous a 31 speaker system is terrible for my ears but there you go! Love everything else about the car. Any advice would be appreciated. I would HaTE to trade this in down the road, because it’s that good of a car.

2008 mdx transmission

Recently had my transmission fluid drained and filled in may, mechanic drained didn’t see how much but added 4qts of the Honda fluid I got at the dealership. Fast foward to July, feel the transmission slip trying to get out first gear once or twice last 2 weeks.

Yesterday drove for about 10 mins and then the car really started thumping when changing gears, I didn’t hear any grinding while driving back home.

Today I when out to check to see if it the transmission fluid was low and that was the cause but I noticed this, I checked it the way it says, turn the car on let it get to operating temperature, shut off and check before 60 to 90 seconds. Does this look overfilled? Car is at 152,000 never gave me issues before especially transmission issues.

2007 acura mdx misfires on all cylinders

Hey guys, my mdx has P0300-p0301-p0302-p0303-p0304-p0305-p0306. Did a fuel pressure test and it was at 58. Introduced smoke trough the intake and no leaks. All the valves were out of spec, so i adjusted them. All spark plugs were changed last month. Any help would be appreciated. I have not done a compression test on none of them cause it happened suddenly. Check engine also flashes.

Purchase price

What was your out the door price? Seems like a lot of add ons to pay for the discount.

Solved 9AT transmission clunking shifts 2020 SH-AWD 135K

Just drained and filled the ZF-9 transmission myself and found out the dealer overfilled it. There was nearly 3.7 QT of old fluid that was light brown so when I filled it with Honda ATF to same amount and ran the engine to the correct AT temp of 115F, about 0.2-0.3 QT of fluid drained out of the horizontal level check hole. This was surprising. And during test drive, the AT shifts smoothly and no more clunking at gear changes. Advice is to follow the full AT drain and fill procedure and don’t cut corners with the final overfill check. by the way - also did the front transfer case at same time. Dealer quoted $600 and I spent 2 hours and $240 for OEM Acura fluids, washers and AT bolts with new rubber seals.

2023 MDX Technology Windshield Replacement

I have a 2023 Acura MDX Technology that's in need of a new windshield. I have been waiting 3 months for the dealership to get an OEM windshield but apparently they are still on backorder. I called Safelite and the can replace and recalibrate next week with a non OEM windshield. Has anyone had their MDX windshield replaced through Safelite with non OEM? Any issues or concerns I should have if I choose this non OEM option? Will I experience any problems or see any differences? Thanks in advance.

More Range?

I took my MDX to the dealer to have a bad starter swapped out under warranty and now getting 391 miles of range on a full tank?

For reference, the most I had seen before based on my driving habits was 340 when I was doing a lot of highway driving and maybe 315 if I was doing a lot of city driving.

I am assuming this will drastically change the next time I pump? Anyone seen this on their MDX?

Transmission fluid quantity?

What’s the correct amount of transmission fluid? I recently changed the transmission fluid on our 2025 Acura MDX fwd w/technology package with 36K miles and I measured & replaced the 4.5 quarts, however, owners manual says 3.4 quarts. Is it possible the manual is wrong? I only accessed the drain & fill bolts because I have trouble finding the fluid level bolt. Thank you
