Elantra MD (2010-15) :: 2012 - Average MPG Fluctuates Randomly
Feb 7, 2014
I've been driving my 2012 elantra for 3 years now, and the average mpg (on the screen) fluctuates anywhere from 18 to 25 during any given trip (I don't take long trips - after 3 years I only have 14,000 miles on the car). I rarely drive on highways, so I'd expect the average mpg to be in the lower range -- but my lease is up and I'm trying to figure out if this is just a gas guzzler or if there's some malfunction of this tool, or if it's something inherent in the way I'm driving.

I have had my 2011 Elantra limited since April. I always have the ECO mode turned on. The light fluctuates when driving as I excepted to. I know the actual mode/light doesn't really do anything, but in the last months or so, it will light up shortly after starting the car and work normal but then decide to not light and never come back on until the car is restarted. I have checked numerous times and the ECO mode is ON.

I just got my elantra on monday and on wednesday the usb connected great to my iphone 5s. Well on saturday I tried connecting my friends iphone 4s and the connection was horrible it kept going in and out a few times like it was trying to connect and eventually gave up. We thought maybe it was her phone so we tried mine but it did the same thing. Why its doing it? I just think its weird that it worked wednesday but on saturday it wouldn't connect to anything.

Have cruise control randomly shut off? Mine does it maybe 1-2 times a week and I use it quite extensively. It pretty much only happens while on the highway. I know I'm not accidentally tapping the break, because it'll happen even when I have both feet away from the pedals.

2012 Hyundai Elantra. My alarm goes off randomly. About 3-4 times a day. Is there an easy way to shut off the sound so it will never go off? Naturally, I don't want to lose any functionality of the remote/smart key or the push button start. Just to eliminate the beeps.

2014 Elantra SE with premium package, I've had it a little over a month. Last week the ac plug stopped working in the passenger seat area. BF said have them check at first service.
Now the trunk wouldn't open with my key fob, or the spare. So I thought maybe a shopping bag handle got in the way. On the way home from the store, the trunk open light popped on randomly. Trunk wasn't open. Okay, that's odd...
Now the alarm has been going off randomly. 3 times in the past 2 hours, I'm wondering if it's a massive electrical problem waiting to happen.

The trunk of my 2013 Elantra GLS pops open randomly when the car is parked, unoccupied, and I am well away from it. This happens about once every week or ten days. Last night it popped open during a heavy rain and the trunk was soaked. I can not trust the trunk as a safe place for anything of value. I suspected at first that the remote was doing this by somehow getting squeezed in my pants pocket, but I can not cause it to replicate this by pressing on the pants pocket or squeezing the remote against the key or a pocket comb or such. I have considered abandoning the remote but with no trunk key that is very inconvenient.

I have a 2013 Elantra GLS. Several times in the middle of the night the alarm that sounds when the door is locked just starts chirping randomly. Why that is?

Ok, so I've had my '16 SE for about 3 weeks. Last night, I noticed the tire pressure was way too high (41lbs in the front and 39lbs in the back). So, I let the car sit overnight, and set all 4 tires to 33lbs this morning.
Ever since I did that, every time I turn the car off, the Average MPG display (on the dash) keeps resetting to 0. I took about 5 trips today, and it keeps happening. The ECO app on the radio shows my previous trips, so I know that the data isn't being lost somewhere, it's just not being displayed anymore. Basically it's acting like I trip MPG system now.
What could cause this, or what setting I should change to fix this? I messed around with it for about an hour, and can't figure it out.

My car just started doing this. It doesn't seem to matter if I'm at around town driving speeds or if I'm on the highway. The car does it in both recirc (max A/C) or in normal. I want to try changing my fliter first but I don't knwo where it's located or how to do it.
The car is a 2008 Elantra with 64K miles on it.

We decided to take a chance on Hyundai (never owned one before) and get an Elantra. Anyway, the car has 2,000 miles on it. My husband was in stop and go traffic today on the interstate and said the car just randomly turned itself off, out of nowhere. He started it back up and had no problems after that, but I am very concerned. It makes me question the reliability of the car to be honest. We've only had it 6 weeks! I am wondering about whether to take it immediately to the dealership or wait to see if it happens again. I don't want my husband going down a hill or something and the car randomly shuts off, so I guess safety is an issue. What would you do?

On average, how many miles do you average between fill ups. I understand that this is all dependent on everyone's respective commutes, road conditions, ability to charge at work, etc., but i'm interested to know what you all do on average.
I'm still on my first tank and have 905 miles with one bar left on my tank.

I just upgraded from a 2004 Prius Six to a 2012 Plug in Advanced. My wife used to love watching the average mpg for the current tank of gas as she drove, and wants to know where to find that display on the new car. For some reason, I just can't find it and couldn't find any reference to it in the FAQ. Am I missing something simple? That number was her favorite incentive.

About 4500 miles ago, I had the timing belt, water pump, thermostat, and all the accessory belts replaced and now, the water temp gauge sometimes rises rapidly from "normal" all the way to the "red" and back within about 15 seconds! This is on a 2006 Elantra GT
Should I replace the "coolant temp sensor" or do I have a real problem that needs repair?

Well, for the past few weeks the weather in Los Angeles had been a little on the cool side. I didn't notice the cooler weather, but I noticed that the computer says I was getting around 51 MPG for almost the entire tank (the warning was blinking so I think I used about 10 gallons).
Then today, the temperature rose to around 90 degrees. I noticed the heat. All of a sudden, my computer MPG rose to slightly above 52. I think that would be difficult to do as it must average out the entire tank an extra 1 MPG. And correct me if I'm wrong, but if I got 51 MPG over 10 gallons of gas, in order to raise the gas mileage by 1 MPG in the next gallon, I must get around 62 MPG for that last gallon.

We've had our 2013 RX350 CPO for about a month now. We traveled to NC a few weeks ago and I noticed that the speedo would read 70 but the computer Ave. MPH would read 4 mph less. This was using cruse on the highway. In about an hours time I zeroed the Ave. MPH a couple of times only to have the same result. It still is happening at any speed. Is it a dealer issue?

Basically, I think my Corolla isn't calculating the MPG correctly. I had to take my car for some major body repairs. When I got it back, most of my settings on the radio and speedometer were reset (time, radio's tremble and bass).
Anyway, before all this body work, it was at 27.7 MPG. My daily route changed. I used to go on a 13-15 mile commute 4-5 days a week. It wasn't a highway, but still a straight road with 4-5 stop lights. I would get 28 MPG, which I think is the max city average for my model.
Then after the change, it started going down. My routes were more quick (probably no more than 6 miles), but I still had the 4-5 stops basically. So I understand this slight drop in average MPG (28 to 27.7).
However, after the body work, the MPG average must have reset. B/c when I checked it, it was at 20 MPG. Which is very odd. I would have noticed if I was burning that much fuel. I don't think that is correct.
And I think the problem is that my average MPG will actually go down when I leave my car in park. So.... I tested it. I reset the MPG average. When I went to the store, I drove normally. I got 30 MPG (pretty straight road, 1-2 stops, 3 miles away). When I stopped and put it in park for a few minutes, I noticed it going down by 0.2 about every 15-20 seconds.

For a few years now my 2012 elantra has been pulling to the right. I got new tires and a alignment yesterday and it hasn't seemed to fix the problem. Now I think it must be a bigger problem than just the alignment. What the problem could be? I will probably take it into the dealer and see what they say.

I have a rattle in the dash up in the middle of the dash kind of in between the two sides of the car and between the window and front so basically right in the middle of the dash, if I slap it with my hand I can make the same sort of rattle so something is loose, bad thing is I dropped by dealership and it didn't do it when I was in the car driving with the service guy but I slapped on the dash and you could here a something loose sound rattle same kind I hear when driving. He said that is normal for things to make noise in there when you tap the dash. About a week ago I had the dirty sock smell coming from my vents so I took out the Cabin Filter and sprayed Lysol in the intake the put a new filter in. This is about the same time the rattle started. I wonder if the Lysol might have made something come loose in the vent system.

Just got rid of my 2011 Audi a4 for 2012 Elantra Limited with tech pkg. I like the car a lot but man is it noisy at highway speeds. Really makes phone calls and radio listening difficult.
