r/Acura_MDX

Wondering if anyone has been running regular gas in their Acura V6 non-Turbo engines. I know it's recommended to use premium and regular gas will lower the HP and fuel efficiency (Possibly?) What is your experience with regular gas? Any noticeable difference?
Thanks

2022 RDX A-Spec Advance (Apex Blue) and 2026 MDX A-Spec Advance (Performance Red Pearl)

Bought my wife a brand new 2026 MDX A-Spec Advance in Performance Red Pearl. Had 5 miles on the odometer when I picked it up at the dealer...then drove 200 miles home to completely surprise her. She loves it.

Always been an Acura fan dating back to my 2005 TL, and obviously as can be seen my daily driver is a 2022 RDX.

We traded in a 2020 Hyundai Palisade Limited we had since new, which we really liked but it was starting to run into some issues and quite frankly turned me off a bit to getting another one even though they continue to put out a good product for the money.

The only thing that was in the running besides the MDX was a Lexus TX350, but the styling was a bit polarizing and overall a little boring in comparison to the MDX, plus not crazy about the 4-cyl turbo in that thing.

Just ordered WeatherTech mats and going to get the front two windows tinted to match the rest of the factory tint. Only thing I'm struggling with if if I want to pay $2K to have PPF applied to the whole front end...we do plan on keeping this thing for at least 5-7 years, but that's a lot of money.

I don’t know about any of you other MDX owners, but my 2025 has the loudest interior as far as rattling and shaking goes. I swear every bump I hit something rattles inside. All of my piano black has rattled. This is the second time I go back into the dealer to fix it. But even the back seats shake like no other at highway speeds. Over a small bump on the road everything in my car that’s inside as far as items rattle. Even my water bottles or tumblers shake in the cup holders. It’s beyond frustrating. Anyone else having this problem? I mean I have a 2016 Mazda CX5 that doesn’t rattle at all compared to this thing.

Own a used 2024 MDX Type S, purchased at a dealer about an hour from home. Had full certification service done when purchased, etc ...

Recently brought it in to dealer closer to home for required service as prompted by vehicle. I waited for vehicle and Rep came out to tell me due to vehicles mileage certain things needed to be done. I know they're always trying to upsell and service is where they make a good bit of change. The stuff he suggested due to mileage had been done as part of certification service less than couple of thousand miles earlier. I pointed that out and his reply was that he couldn't tell what had been done at other dealer. I refused that portion of work.

Now I get email from original dealer that certain service is overdue, which is what I had done at my local dealer.

Do these dealerships not share service info in a common network of some sort? Ridiculous for a "luxury" brand. Of course convenient in order to sell unnecessary stuff.

Just went on a long road trip and I kept getting “driver inattention” messages with a cup of coffee. Sometimes it was orange. But I was focussed. I even moved around to see if it would go away. Does anyone know what causes this?

Hi, I'm in the market for a new vehicle and I love the MDX. I'm currently in a 2019 Tiguan and would like something a bit bigger and something more reliable. I was told the Tiguan has a valve stem seal issue and I just want to trade it in now. I'm currently looking at a 2023 MDX AWD w/Tech for $37,995 with 38k miles. Dealer won't budge on price & offering 7k for the trade (I still owe 2k) I can put 5-7k down on top of the trade. With taxes & dealer fees I am looking at $41,062 total and Financing 30k. Payments are around 497 for 72mo. & 6k down. Does this seem like a good deal? The car was in great condition, 1 owner and bought after a lease. I can see the car-fax shows it went between a couple different dealers since January 2026 and was listed initially for a little less than 35k. The price has gone up I'm assuming due to demand, and I've found very comparable vehicles, but none as well kept as this that I've looked at and a big plus is this one comes with all of the rubber mats. Is this a good deal or should I keep looking?

Hi,

My 2019 Acura MDX owner’s manual recommends putting 91 octane fuel.

However, in my area, gas stations only offer 87, 89, and 93 grade fuel.

Should I use 93? Or put 89 in half the tank and 93 in the other half?

am I being stupid? my plan was to put maintenance cash into my old car so that my two boys could drive it during high school (which starts now).

I’ve had it 15.5 years. 125k miles. I’ve done all the maintenance at the dealer the entire time except for brakes once, batteries, and tires. my dealer usually gives me great discounts on labor so much that when I shipped repairs, the cost difference wasn’t that much.

I’ve changed timing belt, front and back advance shocks, replaced the airbag inflator, alternator. I just took it in for an oil change and standard inspections. it had an airbag warning again too. i had it there one year ago for an oil change and none of the below issues were there at the time.

front axel CV boots are leaking - replace $2k

brakes and rotors $1k

airbag retentioner $1k

power steering pump leak. replace $1.8

$6k all in. I know they are working in aftermarket parts and a decent reduction ($500+ labor discount) because I know these peoples so well. but still

i can see replacing brakes/rotors and airbag retentioner . but change power steering pump and front axel at the first sign of leaking? there are no current symptoms of issues that I can tell when driving.

the car still has a ton of life and I love it. am I on the downward slope and need to cut my losses? or I can do this and still have a great car for another 4 years.

Is it safe to put 87 octane in my 07 MDX, I was told other mdxers have been doing this for years.
