Elantra XD (2001-06) :: Sudden Drop In Mileage And Hard Shifting
All of a sudden my fuel consumption dropped from 28mpg as read from the computer display in the dash, to 21mpg. This was not a gradual drop, it was at 28mpg one day and 21mpg the next day. There is no service light on, do these cars produce codes that don't trigger the service light?
A few months ago the vehicle was getting stuck in various gears and lunging, this was from battery corrosion dripping down and eating away at the transaxle range sensor. I cleaned up the battery and replaced the range sensor and the vehicle was driveable again. It re-learned the shift timing and seemed to be ok, then about a month ago it seemed to be forgetting the learned shift positions after sitting over night, I replaced the battery, thinking it was in a marginal state where it would forget the program while sitting. The shifting is still hard sometimes but this seems to have worked but, now my mileage is horrible.
I thought I'd just change out the oxygen and air flow sensors but, then looked at how much they cost now, and realized this would be some costly trial and error. Is there a methodical way to troubleshoot this issue, any way to pull the sensors and measure them?
Elantra XD (2001-06) :: 2002 HYD - Engine Misses Sporadically Often Every Time After Fill Up
My daughters 2002 HYD Elantra engines misses sporadically often every time after a fill up. What it might be. Once some of the gas is used then it stops.

I have an '02 Elantra GLS Manual Trans 91000 miles and every time I gas it up I have to rev the engine until I get moving or else the engine will die. It only happens when I fill up and I do not top it off. Also it has tried to keep running after I park and take the key out. What may be happening?

When I try to start my wife's '06, it takes a little bit longer to start than in the past (used to take only 2 turns or so, now it takes 3 or 4). When it does finally ignite, it's a rough ignition and then it goes to normal. Why this is happening?

I bought a new 2013 Hyundai Elantra Coupe this past August and this is my first car.
My first concern was that Hyundai advertises 27mpg in city and around 37(?) for highway. I acknowledge the fact that Hyundai recently had to lower their mpg estimates for some of their cars and provide reimbursements but however, these reimbursements are for 1-2mpg difference. My car after more than 6 months is still only getting about 14-15 miles on a casual drive in the city and only about 19-20mpg combined and about 24-25 on the highway! I am only getting about half the estimate for in city! I do not drive aggressively. In fact I am a pretty safe driver since I am a new driver and cautious about everything. I am also using premium gas on my car. I called the dealership I got the car from and they were trying to tell me about the reimbursement program which I already knew of... The reimbursement based of the 1-2 mileage difference is not what I want. I want to fix it and get close to the estimated mileage as I can. What is the best way to go about doing this?
The other issue is that sometimes when I hard brake, my car makes a loud grinding noise. My dealership's service center said they could take a look at this. I was mainly wondering if there is anything I should be concerned about for this?
Elantra XD (2001-06) :: Gas Tank Will Only Fill About Half Way Before Clicking Off
At seemingly random times when I take my Elantra to the gas station it will only fill the tank about half way before clicking off. After doing some quick google searches I'm leaning towards something being wrong with CCV system. I read that over filling the tank can cause debris to clog the system and a few months back my father-in-law borrowed it he has a tendency to overfill the gas tank. But I've also read that there's an error code that tends to pop up with it and so far there's been none. Either way I'm not familiar with how the CCV and related systems work.

So I recently bought a Hyundai Elantra Gt 2003 that I totally love. But ever since I bought it, it struggles to turn on. It makes a cranking noise before it turns on, and it takes about 2 to 3 times for it to fully turn on. I changed the crank shaft sensor and the fuel pump. What can it be?
View 1 RepliesElantra XD (2001-06) :: Cannot Fill Fuel Tank / Gas Overflows When Filling
I have an 04 Elantra GT. My gas gauge is showing full but the car is running out of gas. I try to fill the tank and I get the annoying click and after trying for a few, gas comes up the filler and overflow tube and makes a mess. At the same time, I was getting a P0449 code. I got an evap canister from the junkyard and that seems to have gone away.
Tried diagnosis but dropping the fuel tank to access the lines. When I jack the tank back up into position, you can hear gurgling sounds and as if the gas is coming up the fill tube. I also opened the access panel under the seat to see the pump assembly and when I removed the 8mm bolts, gas came pouring out. There was definitively gas in there. Checked the float on the pump assembly and it moved?
There is also something at the fuel neck at the top. Don't know what it is and if that could also be part of the problem.
Elantra XD (2001-06) :: After Fill Up Car Will Occasionally Sputter Or Sometimes Stall During Idle
I just picked up this 2005 Elantra last month. She runs GREAT - except after filling. Then she will occasionally sputter or sometimes stall during idle. Otherwise, if tank is below 3/4 (approximately), she runs fine.
View 7 RepliesElantra XD (2001-06) :: Gas Vapor Lock At Pump Won't Fill Tank
Son was unable to fill his car's gas tank, 2002 Elantra (but happens to all cars sometimes).
The vapor lock on the pump kept shutting the gas flow off.
This was caused by the tanks vapor exhaust being unable to exit while filling, so the only place to go was back up through the gas fill hole.
The charcoal filter had sprung a leak so the zillions of tiny little charcoal pellets pour from the filter into the rubber hose clogging it.
The Filter is $150 at Hyundai. Not available at AutoZone or OReilys.
Very simple to replace a couple bolts a few hose clamps.
Strange problem, thats no one at work had encoutnered before. A few Hyundai mechanics had heard of it and worked it before.
Also could be Purge Valve or Vent Valve solenoids...search EAP system too if your having this issue of not being able to fill your tank with gas, without 500000 vapor locks shutting the pump off!
Elantra XD (2001-06) :: Cylinder 2 Misfire / Rough Idle Especially After Fill Ups
I have a 2001 Elantra with 170K miles. well taken care of. I've been having a rough idle issue for some time now. The car idles very rough. I checked for codes and I got the cylinder 2 misfire code (P0302)...
I started out and replaced the plugs and wires, no solution...
I replaced the coil packs, no solution...
I replaced the MAP sensor, no solution...
I figured it may be no to low compression, so I did a compression test and all cylinders came back normal, still no solution...
I figured it might be a dirty injector, so I poured some seafoam in the gas tank, and no solution...
So my next step is to switch out the injector. Is there anything I am overlooking?
Here's the big thing that is happening too... Everytime I fill up the gas tank, I turn the car on and it idles even rougher. Like if you talk while sitting in the car, you sound like Chevy Chase when he is on the vibrating bed with Beverly D'Angelo in the movie vacation! LOL. It slowly goes away after 10-15 minutes of driving. All this rough running engine ONLY happens at idle, otherwise it runs very smoothly.
Accent MC (2006-11) :: Hard Start After Adding Fuel Or Fill Up
My 07 has difficulty starting, only after adding fuel, or a fill up. I thought at first it was due to over filling, but it occurs after adding any amount of fuel. If I leave the car running while attempting to fill up, it sputters and dies. I have to press the gas pedal to the floor to start it, and it sputters for a few minutes, then runs fine, and starts fine until fuel is added once again. I searched and found where the General mentions a Vapor hose, but could not find more.

Just bought a used but in pretty decent shape, 2002 Santa Fe, with 6 cylinder engine, 112K miles. I read the post about the vehicle that was hard to start after filling up - but this one is hard to start all the time - every time. Cranks fine, but once cranking, have to pump the gas pedal several times, and then it chugs just a second and then starts running. Slilght smell of gas if the hood is up, just after starting. Once running however, it runs perfectly on city and hwy. I have one mech that tells me "definitely the fuel pump" and another that tells me "definitely the purge valve" - this of course just from me describing the conditions, they have not actually seen it.

I have no problems pumping gas in, but the entire car cabin smells very strongly of gas after filling up. It seems to come from the area of the charcoal canister. No dripping of gas, no puddles... Did a smoke test, no leaks showed up anywhere (according to the mechanic). I do not want to start throwing parts at this to fix it - where should I start, and in what order should I throw parts? 2003 elantra GT sedan, 70k ....
View 1 RepliesElantra MD (2010-15) :: 2012 - Gas Fill Up Cut Off Shortly After Start
At many, but not all, gas stations, as I try to fill up the gass flow cuts off very shortly after I start. No matter how I position the nozzle it cuts off. if I squeeze the trigger just barely so the gas flows slowly, then it will remain on, but takes forever to fill up.
Again, doesn't happen at every gas station, but a lot. Based on that, I'd assume it's not a malfunction in a valve, filler neck, evap canister, etc.
Elantra XD (2001-06) :: 2002 Won't Start After Driving
This has been happening for awhile now. I will drive somewhere, distance isn't a problem, and then after I'm done, I'll go to start my car, and it won't start. It won't turn over or whatever the term is. The starter tries, but won't bite. Sometimes it will start and I can drive for a bit before it will die about a block or 2 later.
