Hello all,
I've now had my new 2017 SH-AWD MDX Advance for almost two weeks, using Premium fuel and my MPG's are poor as per the vehicles computer and what the SUV is supposed to get (19mpg city & 26mpg highway).
Using either 'Normal' or 'Comfort' mode I am getting 9-14mpg around town - this even when "trying to maximize by coasting and no hard acceleration. During my one mixed use trip when on the interstate for a couple of hours I only got in the high teens.
So here are some details:
Leased with a full tank on 2/18, MDX had 79 miles on odometer
MDX now has 576, I've put 497 miles on it and have already filled the tank twice with an overall average of approx. 16mpg
Current tire PSI is showing on AcuraLink app as between 37-39
Has anyone experienced this or know of any issues/fixes?
Am I expecting too much?
Secondly, during this just under two weeks period my tires have all lost air. No cold weather influence as I live in South Florida but down 2-4 PSI during this timeframe. My last vehicle didn't have the computerization to show this info - should this be a concern? Perhaps this goes back to when we're told to check tire pressure weekly..?
I have a service appt. scheduled for early next week for the dealer to check things out but am concerned.
Man you're just riddled with issues huh? This and the infotainment. Sorry
Anyhow, are you in Drive, seen as "D" on the MID or Sequential, seen as "S" on the MID? Seems like a basic question, but it would drastically effect your mileage.
A fluctuation of 2-4lbs per tire from cold to warm/hot is perfectly normal.
That's strange. I've put just about 600 miles on mine with 2 fill-ups. One from the dealer and 1 from me and still have about 30 miles left. I show 18mpg. My tire pressure is between 32-33. I'm in Orlando
I run my pressure a little on the high side (38-39lbs cold). I get at least 22mpg in town/mixed and just completed a 700 mile trip about 80/20 highway to city driving and the computer reflected a 25.7mpg average (76mph cruise on the interstate). The first thing I would suggest is to hand calculate your MPG to see if it is a computer issue. Same thing with the TPMS. Hand check it to see if it is the pressure, or the monitoring system.
I hope it works out for you. It's tough to drop big coin only to have issues.

Are you getting the info from the Trip computer ? Highway i get around 25-26, locally its horrible... 14-18. I miss my hybrid
Computer, but the rough estimate seems on based on the total miles I'm getting per tank. I'll check manually and report back as soon as I have a city tank under the belt again.
Interesting comments from all - thanks!
Yes, MCDavis, several issues since taking delivery on 2/18 & 1,006 miles. After just under two weeks we got the AcuraLink aspect working. Mileage continues to be poor with the transmission in "D" and using 'Normal' mode - even tried comfort. I called the dealer who asked me to bring the vehicle in for SVC to check it out but upon arrival I was provided with several responses: a) SVC writer said and I quote, "wow, that's great mileage for an MDX", b) a tech specialist and the service manager both indicated that based on their "personal" Acura car experiences my MPG would improve once I get to my first oil change at 5k miles. All of the above are unacceptable, the manager was not pleased that his writer said it was good mpg but the statements that after 5k miles I'd see a dramatic improvement were seemingly absurd.
Yesterday I called Acura Client Relations to run this by them as I am of the opinion that "break-in periods" ended many years ago! They agreed and I am in the proverbial 24-48 hour waiting period to hear back - they said they'd contact the dealer on my behalf.
I have verified the MPG manually and it is close to the system's readouts:
- Most recent mileage: 220 miles of mixed HWY/City = 16.7
Tires have been in the range of 36-39PSI - I just checked via the link app & all four tires are showing 38 PSI
One thing I find interesting is that after each fill-up my MPG is in the single digits for a while - even if I coast along the main road heading
kareshi: I have not used the remote start
Appreciate this forum and having the ability to learn of others experiences and share mine.
I had my MDX Tech for a month now. First fill up from the dealer and I am getting almost 400 miles but I have doing a lot of local driving so I average about 19.6 mpg using the Normal Mode. Tire PSI is 37 all around.
I just did a 2nd fill up last week so will see what is my outcome. I have about 435 miles on my MDX now.

Quick follow-up: I heard from my dealer this afternoon, the service writer saying he was told by his manager to call me and have the MDX brought back for them to check it out. Apparently they had been contacted by Acura Client Relations and perhaps now they will take my concerns seriously - I appreciate the fact that Acura followed-up as promised! They will have a loaner for me and hopefully, they will figure this out - I simply want to enjoy my new SUV and stop regretting my choice. ;-)
What was sadly (somewhat) amusing was his opening comment that he "heard I was unhappy with my gas mileage". I replied that I was just in front of him in his office less than a week ago voicing the same concerns and he had replied that I should be happy with mpg's in the low to mid teens - that the EPA ratings were based on a single person in the car and a tailwind! I know better than to expect EPA numbers and perhaps that he was not totally serious but c'mon man.......a new owner does not want to hear such nonsense.
Interesting. I have been getting mostly 16.5 mpg as well in my 2016. My tires are also inflated to 38/37. I just figured that I drive harder than normal folks so my mileage is what it is. I have been able to get 20-24 mpg though if I just calm down and take it slow. Then highway cruising is 24-28 mpg.
I was driving on the freeway to pick up some stuff from my house to my destinaton (10 miles 1 way) this morning with the IDS at Comfort and I was averaging 19.4 mpg at the speed of 70MPH. I just been getting 19s local or highway on my 17 MDX every since I got in on Feb. Never over 20s.
Hello all - so it's now been 5 months since I took delivery of my 2017 MDX and I am still, for the most part, seeing abysmal MPG. Of my four most recent trip computer records I've gotten 13.4 mpg (74 miles), 16.2 mpg (224 miles), 14.2 mpg (201 miles), and 13.0 mpg (33 miles). PSI today is recording as 38. I am always pumping premium gas and have changed brands/stations to see if there is any difference. I am at a loss as was the dealer. I'll have it there again for an oil change but do not have any high hopes that they will magically figure this out. I will also add that I am not a hard drive and have actually focused on smooth and easy driving in an effort to increase MPG.
Adding to the frustration' is I'm only 5-6 months into a 36-month lease. Strongly considering doing the math on what my cash loss would (or might) be if I worked to terminate the lease by trading in the car, selling it to CarMax or AutoNation and then starting over again. Figure if I go with a lower monthly payment and double my gas mileage the ROI will make sense. Other than the MPG it's a great SUV albeit somewhat bigger than I actually needed.
This is the 9 speed transmission - right?
What gear does it show when you are doing 70 mph on the freeway?
Why can't the Dealer figure this out? Did they give you any explanation?
In my previous MDX I typically saw 19-20 mpg in local mixed driving very consistently. On the highway at best I might see 27 mpg at 70mph (+/-). There were many times I only saw 17-19 mpg in city only driving with lots of idling in traffic.
Now that I have the MDX Sport Hybrid I am seeing a much improved mpg spread. In typical mixed driving I see 27 mpg very easily, and this week that I am driving almost entirely highway, I am very solid around 31.7-32.5 mpg for the tank thus far.
Could it be software issue making your MDX having bad MPGs? I can as my friend works at Honda HQ and see if they have issue on it
That would be most appreciated - thank you!!
I have not spoken with my dealer in awhile as they had checked the MDX out and claimed everything was fine. My MPG briefly improved but over the past month or so it's fallen to the same low numbers I had when I first picked it up in February.

Hello and yes, it's the 9-speed transmission. When you ask for gear, it shows "D", where do I look for other information - I have not done so previously.
Dealer checked out the SUV awhile back and claimed all was right/correct; MPG improved but over the past month it has fallen again (trying different gas stations Premium).
What speed are you seeing 31+ mpg? I have a weekly trip that is 90% freeway and most I see is 28-29. I am usually going 70 to 78
As of last night I have driven about 229 miles on the tank, am just at the 3/4 fill mark and have 412 miles to empty with a new average of 30.7 mpg on the gauge. This is almost entirely highway miles with a little stop and go at bridges, tunnels and tolls. Almost all rolling hills when they appear and driving at around 70mph on the top end yesterday but more of the travel in the 55-60mph range. I know how to finesse the mpg out of the vehicle after driving them (hybrid power system) now for 2.5 years. It takes practice, but if you are gentle with the throttle, basically driving like a limo driver (meaning very smooth), this mpg is completely repeatable. In a few weeks I am driving to the Washington DC area again and this time it will be in the MDX-SH so it will be fun to see what I can coax out of the vehicle regarding mpg for the trip. That is almost entirely a flat journey from New York.
For comparison reasons, the RLX-SH right now has 298 miles on the tank and it is just above the 1/2 fill mark with 235 miles to empty with an average reading of 31.4 mpg.
Full disclosure, I do add about 2 gallons after the shut off at the pump on a regular basis. You can add 3.2 gal to both vehicles tanks if you filled it to the brim (not recommended).
Is your MDX a hybrid? I'm guessing not, but even so that does not look right. Something is definitely wrong if that is the range to empty on a full tank. That would assume your last miles before a fill up was in the mid teens. Does your actual mileage improve? If you do the math on miles driven and gallons used, does the calculation back up what the mpg meter is showing?

Not a Hybrid, SH-AWD. When I have checked MPG manually it has closely matched the computer......unfortunately. I've seen great mileage on one road trip of mostly highway....as in 26-28mpg but that is rare. My combined driving has produced low teens to 16.6 on occasion. Overall the mpg has been well below what was and is expected. I'll need an oil change soon and wil have the dealer check it again but they've previously claimed all was good. Two dealer service guys said it would improve after my first oil change - when I asked why that should matter. they stated that was their personal experience with their personal Acura vehicles.

While your fuel economy may well improve after the first oil change, the oil change in and of itself will have nothing to do with the improvement. The fact is, engines take a while to loosen up before their peak fuel economy is achieved. True story, we bought a fairly large family hauler back in 1998 and took it on a road trip a few days later; in spite of the fact we did literally hundreds of miles of nice easy interstate cruising, the average fuel economy at the end of the trip was an abysmal 19 mpg. Fast forward nine years and 145,000 miles and I took a similar trip with it, overall fuel economy 26 mpg with one tank up in the 28 mpg range, and that was on E10 whereas the first trip was on 100% gasoline.
Long story short, there may well be an issue with your MDX, however, there is also the possibility things will improve with age.

Thanks - I appreciate your input - I can only hope things improve in the near future. I understand about the oil change not directly impacting performance, but (and I am not an auto person per-se) in this day and age I would have expected appropriate performance from the start. Or (wishful thinking, I know) an up-front disclosure from the mg. ;-)
I'd started to calculate my $$ ROI if I terminated my lease and moved to another vehicle with better MPG - not the best thing to do when <6 months into a 36-month lease.
Brand new MDX, mostly city driving, hot South Florida and Im assuming with the AC blasting? High teens MPG sounds about right under those driving conditions.

I would be quite happy with high-teens MPG, just not seeing that (yet). And yes, a/c blowing most if not all of the time.
I think he is on business trip. Testing out cars. He does that every 1 or 2 times a month. He brought over a Civic Type R last month and test drove it like hell LOL
No gear is shown when I switch to "S", what am I missing or not doing correctly?
Thx!
Sorry - should have said to hit one of the Paddle shifters. You can also do this in D. Best is to hit downshift, then you will know what gear you were in. If it goes to 8, you were in 9.

I'm getting almost 22 MPG in city regular and I live in South Florida. Heck, I just towed my flats boat to The Keys (I took 41, so 55-60 mph) and got over 20 MPG towing! Something is wrong with the OPs unit.

2017 MDX Advance & Poor MPG + loss of tire PSI
