So when it came time to trade up, I assumed Acura would have implemented the '07 mileage fix into the '11 MDX models, but I was wrong! I too have been extremely disappointed with the low miles per gallon on the 2011 Acura MDX. Like you, I first only averaged 13 city and 15 highway. I'm now at 4000 miles and am up to 15 city and 18.1 highway. I'm still holding my breath for the 23 mpg highway like I had in my '07 model! Try resetting your speedometer after filling your tank each time. I too hope things continue to improve with the rising of gas prices, otherwise, as much as I love the new MDX model, this will have been a financial mistake!
Appreciate your input.. Thanks.

Traded for a '10 (end of lease) and man am I disappointed about the incredible drop in mileage.
I don't see 21mpg on the EXACT same trip i was getting nearly 24mpg.
I spoke to my service guy and he hinted this was indeed an issue they have been hearing.
Spoke to my salesman who, of course, had a "reason" for lower mileage. Heavier car, blah blah blah.
I didn't hear any of that when he was "selling" me the car.
Anyway, pretty disappointed in the new version. Had I known, I would have stuck with the '08.
2011 MDX Advance
Haven't posted on this site in a while. 2008 MDX coming up to 4 years with around 35,000 miles. Miles per gallon is really bad. Practically no difference between highway and local driving, which for me means around 14 mpg,even on open road going around 70. Didn't realize highway had gotten that bad but then I almost never drive this car -- wife does. Any suggestions on why it might be that bad on highway?
I checked prior postings by me and at around 7.5K I think highway was round 21-23 mpg.
Thanks,
Bill
Has anybody else experienced pinging with regular octane gas?
I am considering the MDX vs Lexus RX350.
Should I be concerned on MPG for MDX since I see many complains on this thread?
This is a common problem with MPG or few exceptions.
Thanks
I am using high octane gas ONLY, as per dealer instructions. I am getting 14 to 15 MPG in city, open road driving I can get 20.8 staying at under 70MPH beyonf that gas efficiency drops drastically. I am driving about 1000 miles a month, so the gas efficiency factor for this car is pretty bad. This car may not be a long term keeper... :sick:
Plain and simple no HorsePower and Good on Gas 24 MPG.
SO now with the 2011 MDX base model I make still continue to do trips from NYC to Florida Jacksonville area and the best i am getting is 20.8PMG.
I am towing full luggage for 3 kids and 2 adults plus a all the junk for the kids.
gas consumption is not going to get any better than 21MPG. That is the bst I have gotten, the worst has been about 14MPG city driviing.
I am dissapointed with the mileage I get with this 2011 MDX.
I am about 18K and 16 months into the life of this car and I am not liking the mileage per gallon...Acura did not live up to expectations!
My suburban "city" driving will differ from yours unless you live in my neighborhood and drive like I do. That being said, I've driven in "city" situations briefly, and only 3-4 times and got 17.4 to 20 mpg in those scenarios - always w/ac on.
All this is from a brand new vehicle. Not yet broken-in. Amazed. IDS in Normal mode most of the time, but I switched to Sport mode when traffic thickened or roads/offramps got curvy.
BTW, SH-AWD is not just for snow. I'm sure it rains where you are, and SH-AWD should yield measurable safety benefits (shorter braking distances and better handling) in both wet and dry conditions. Ironically, FWD savings comes at a cost. Hope this helps.
That being said, I have only had the car a few weeks and it is still breaking in.
I do ALWAYS put in the 93 octane (BTW)
Some city tactics I use are relatively quick bursts of acceleration followed by coasting at speed as much as possible to allow the engine to go into 3cyl mode. Remember, contrary to popular belief, slowly accelerating to speed uses slightly more fuel than the above. Also, accel down hills fast enough to coast up and over them. Going over the speed limit in the city is also an unfortunate necessity when trying to get good mileage because you can't gain much momentum (and thus can't coast much) if you're driving 20-30 mph. But again, your city mileage will vary. If you were to somehow exactly duplicate the EPA city test cycle (virtually impossible since they don't actually drive the vehicle on city streets), you'd probably match the 20mpg city rating advertised. Absent that, you'll likely get less. From my own experience, it's easy to beat the EPA hwy rating. Despite a 700 mile trip from MD to NY and back, I haven't had a chance to do any measurable city driving - just hwy.
All 14 MDX's are breaking in, so everyone's mileage should slightly improve over time. I too always use premium (91-93 octane). Coast baby, coast! Hope this helps.
To avoid the vibes, you can put the trans in sport and downshift using the paddles when revs get down to 2000 rpm. But we shouldn't have to do this to avoid vibrations in a a premium brand vehicle. As more MDX miles are driven, more will report the issue. I'm going to bring this up when I bring mine in for the first oil change. I'll let you know.
BTW, has anyone experienced low rpm vibrations under light acceleration? I've posted under "MDX Vibrations" check it out.
I came here looking for lower MPG issues I started noticing in my 2012 MDX. My driving is mostly city with occasional highway. I have been recording the MPG shown on the car and the actual MPG (computed) I get for every gas tank filled and noticed that after around 11K miles driven in Chicago suburbs, I got around 18 MPG (computed value) so far while the trip computer shows 17.7 MPG. I always full the tank and fill it up mostly with same brand (Mobil) at same gas pump as much as possible. I am very careful with driving habits and do not accelerate too hard. I try to keep the air pressure in tires around 35 PSI (measured after 3+ hours of shut off). But with the cold winters, it goes around 33 PSI relatively soon.
I noticed few issues so far:
Has anyone else noticed such issues?
Reading the manual, I reset the average speed indicator and now I do see this info correctly. However other two issues still persist.
I just bought an used 2006 Mdx. it has 93k mileage. I think i made a big mistake by buying this car. Never ever again am I buying this. I only or mostly drive in the City where so much traffics in New York City. my screen shows average mileage of 11 mpg. I don't know why that is so low. I haven't checked it out by technician yet. I will eventually in the coming months. I think i get better mileage when i drive on the highway but i haven't checked the numbers.
I use high octane gas >93 but still mileage don't improve. any body got any suggestions?
That's a bit low - 15 city is the EPA rating. Different people get different results of course, and you're in a bad driving environment for fuel economy. You can scroll back through this discussion for tips, like checking the tire pressures. And don't drive like a New Yorker (I doubt that you could do that and survive in the city though!).
Premium unleaded is the required fuel for your MDX.
I own an 2011 MDX base model.
I have to say gas consumption in the city is Horrible. However, in the highway its a different story. I can have the car loaded with 7 adults traveling at 55MPH and I can get about 21 0r 22 MPG cruise control engaged. I only put high octane gas and I now have 33K miles.
Most of my driving is long distance from NYC to florida, Georgia and Alabama, my usual trip is about 3K to 4K mile trip and I can always get about 21 mpg on average with 4 adults and luggage. Great car for long trips. I hear the 2014 model gets better gas mileage because the AWD is an option but why would I buy an MDX without the S-HAWD?? makes no sense!
Maybe if you full-timed it in Florida the FWD would make more sense.
Your comments about mileage seem pretty "normal" or better than the norm on the highway. My current minivan's sweet spot seems to be cruising along at 70 mph. Hit town and the mpg drops 4 to 6 miles per gallon.
