How to up MILEAGE ON HYUNDAI???

Any sugg on getting better mileage. 2003 ELANTRA . Spec . tuning ??
computer updates?? Help !!!

 

Accelerate slower, and use your momentum effectively (e.g., don't
accelerate into a stop light).

My boss increased the size of his air intake on his jeep and got much
better mileage at no cost. I don't know if the same can be done on an
Elantra. I'll leave the technical stuff to the gearheads here.

Trade it for a Honda or Toyota.Chances are the transmission is going to fly
out of it within 2 years anyway.

 

That transmission happens to have a 100K warranty, so don't look for
it to do any flying for a few years.

 

Hyundai vehicles have very restrictive intake and exhaust systems.
Open either up wider and you'll not only see better gas mileage but
more power as well.

 

Interesting. Makes you wonder why they don't do that to begin with.
I'm curious.

Perhaps it is something to do with pollution certification?

Less restrictive intake and exhaust systems are noisier, though not
necessarily to an objectionable level. If you go to
www.elantragtclub.com, there are DIY instructions for intake and exhaust
modifications and numerous discussions on these subjects in their
forums. Another good site is www.elantraxd.com.

I've removed the intake resonator on my car (easy, no cost, no added
noise that I notice) and will probably replace the stock intake with a
cold air intake system (aka, a "CAI") eventually, once I decide which
system to go with.

The rear muffler is known for being restrictive, so that will soon be
replaced with a Magnaflow. Again, you can do this without adding a lot
of noise if you select a muffler of similar size and configuration.
Magnaflow has information on this in the FAQ section of their web site
(www.magnaflow.com).

A change to synthetic oil in the engine (0W-30 or 5W-30) and
transmission (if you have a manual trans) should help some. I'll be
doing both once my engine is broken in a bit more (at ~6000 miles).

Still, as another poster mentioned, driving style makes the most
difference. If your car has a trip computer, use the MPG readout to help
you learn the effects of various driving techniques.

Despite the fact that my car is still new and breaking in, I'm getting
32+ mpg on the highway and ~27 in the city, with an average of 29-31
combined.

 

What kind of BS answer is that? FYI, Hyundai is now rated the SAME as
Toyota in initial quality by JD Power and they're both just one point
behind Honda. Hyundai is a company that takes quality, customer service
and customer satisfaction extremely seriously.

Besides, why would anyone want to pay thousands more for a comparable
Toyota or Honda? A good car is a good car, regardless of the name on it.

 

Here is a another BS.
Wow, there must be two Hyundai company's.
My Hyundai company is not responding to ridiculous full consumption of
1 to 8 -10 liters/km, from my Getz, gives no answer's regarding to the lies
published in there brochures. Unfortunately the name on my POS is Hyundai,
my first and for sure my last, next time I by a Car.

 

Gee, do you think your nasty attitude might have something to do with
it. I'd like to hear the story from their side.

 

Not trying to start a war here. All Im going on is the experience Ive had
with my 2002 Elantra. Its been bad from the get go. Hyundai Canada is not
taking me seriously, or the cars quality, I can assure you that. Maybe I got
a bad one, but its been in the shop more than out. When I hear about them
fudging the gas milage ratings and ignoring problems like the 2-3 upshift
flare, it makes me angry. The car is beautiful, and Hyundais reputation has
improved greatly, but until they FIX actual problems rather than explaining
them as normal operation, they wont move ahead. Its an excellent warranty
also. I needed mine. Over and over again. Now that its expired, Im living in
fear of the next big problem.This is whats been replaced on my 2002 Elantra
so far:
Both ball joints
transmission, engine seal, window tapes, seat, power window motors (4)
rotors, tires(twice) a defective air bag went on its own.tie rod ends
alternator and a oxygen sensor. All under 100,000K. Can you blame me? Canada
has no lemon laws.

Pinokkio must mean 8-10 liters/100Km -- I don't believe that an engine
with that displacement could pump 8 liters of gas through in one km --
it would flood out almost immediately.

Terry,

That's just unbelievable -- no, really...

Tires replaced twice under warranty??? No way... My U.S dealer just
laughed at me when I asked for a tire replacement!

Oh I'm sorry Your a so right. When you by a car from Hyundai, you base your
dissission on the 1 to 16.4 average fuel consumption from there brochure,
but in fact it's not 1 to 16.4, but 1 to 8 or 1 to 10 if your very lucky,
course's you do nothing about it,dont even talk about it. If you do, your
nasty!
But your even more right in your second sense, I do like to here the story
from there side.
Till now I been waiting from novembre last year on.
Just for your information Petrol over here cost about 1 dollar 35 per litre
or about 3,60 dollar per gallon.

 

I understand that.

Perhaps this is an issue with Hyundai Canada? All I can say is that
Hyundai USA has been really good to me, including covering one large
repair when the car (a '94 Excel) was 4K miles out of warranty. I also
seem to have an exceptionally good dealer. Perhaps we're comparing
apples and oranges?

Well, let's examine this objectively.

Of the items you list, the ball joints, tie rod ends, the alternator and
the O2 sensor are pretty typical for any car within the first 100K miles.

Ball joints and tie rod ends are typical maintenance items for
suspensions. I wouldn't expect more than 60K miles out of them and I
wouldn't be surprised if they failed sooner. A lot depends on the
quality of the roads you drive on. Rough roads will shorten the life of
these parts.

Alternators are a crapshoot. I've had one fail in three weeks (in a
Saab) and others last over 100K miles (in a Hyundai). For some reason,
the rebuilt alternators from my local shop have always lasted longer
than the original parts. Go figure.

I've only replaced one O2 sensor, but their life span varies and I
probably should have replaced more of them.

These parts all have limited life spans and they're all manufactured by
other companies. They're also relatively easy and inexpensive to fix. I
don't see how you can count these items as quality problems, unless they
failed very early in the car's life. Even at that, Hyundai didn't make
them.

Tires are obviously a maintenance item and their life span is dependent
on how you drive and the condition of the roads. If you do actually have
a warranty problem with a tire, it's not Hyundai's fault.

I'm curious about the rotors, as they're a common "scam" item that are
often sold unnecessarily during brake jobs. Calipers are the other item
that's commonly part of the same scam, which is well known in the
industry. Employees in brake shops are taught to sell these items as a
means of boosting repair bills. The brake job that was advertised at $50
suddenly costs you $400 if you fall for their lies. Perhaps this wasn't
your situation (were your rotors warped or something?), but I thought
I'd throw it out as a warning to others in case someone tries to pull
this nonsense on them.

On the other hand, the other items on your list shouldn't have failed
and you have a legitimate gripe about them. I'd be concerned, too, but
if they were covered under warranty and didn't cost you anything, I
guess the warranty served it's purpose. If you're nervous about the car,
by all means sell it and get a new one with a new warranty.

If your car's an '02, you sure drive a lot! ;-)

 

No, that's not what I said, but your post certainly conveyed a bad
attitude. As someone who's worked in customer service and support, and
also in retail for many years, I know how much of an effect a customer's
attitude has on the service they get. People who are nasty get poorer
service by far.

Now as far as your problem, by my math, you say that they claimed your
car would get 39 MPG and you're actually getting 19-24. Does that sound
correct? That brings up a few questions:

- Was the advertised mpg for highway driving? (I assume so)
- At what speed?
- Do you drive at the same speed used in the tests?
- What was the city rating? (if there was one)
- What standard was used in the test?
- Who certified the results?
- Was the same type of fuel used? (gasoline/alcohol blends get
poorer mileage)

I'm not trying to let Hyundai off the hook for a legitimate problem, but
if the car was advertised to get 39 mpg on the highway at 55 mph on
straight gasoline and you're doing city driving on a gas/alcohol blend,
your mileage results wouldn't be unreasonable. If you drive 75 mph on
the highway, can't reasonably expect the same mileage. If the tests are
unrealistic but they're certified by the Canadian government, who's
fault is that?

Perhaps I'm completely off base here and I don't claim to be familiar
with the way fuel consumption is rated in Canada (feel free to clue me
in). I'm just trying to make the point that you need to examine the
whole picture before blaming someone.

It certainly appears that there are problems with Hyundai Canada, but
the story seems to be quite different in the US. That's a shame, but it
may well be due to the relative size of the marketplace and the level of
competitive pressure. For example, American car manufacturers build
garbage for decades (some still do) until the Japanese moved in and
showed them how it should be done.

Do other brands which are well respected in the US have problems in
Canada, similar to what you're seeing with Hyundai? Again, there's no
excuse for there to be any difference, but in Hyundai's case, apparently
there is. If I were in your situation, I wouldn't be too happy, either.

If they haven't been willing to communicate with you, you have a right
to be angry. That's inexcusable, period.

I feel for you, but you have to blame your government for taxing it to
death. That's the price of socialism. In exchange for low quality, free
health care, you get an oppressive government and confiscatory levels of
taxation. Sounds like a raw deal to me. Our system needs a lot of work,
no doubt, but I definitely prefer it.

 

Ok, lets start all over again.
First I live in the Netherlands not in Canada?
Hyundai claims in there brochure about gas millage:
12,5 km per liter petrol for city driving
20,0 km per liter petrol for high way driving
16,4 km per liter average (city / highway combination)


I'm driving almost only highway (90%) at a moderated speed
of 100 km/h wich is 60 mph.


The Getz then scores about 8 to 10 km per liter.
At first I blamed my car but in the meanwhile I found a lot
other Getz owners with the very same extreme high fuel consumption.
Even test drives from car magazines having the same conclusion.
A miner group of people claim's around 12 to 12,5 km per liter, but
for a small car even this is far to much.


I ben driving cars and bikes for 30 years now all kinds of and
without any exception with al of them I used less fuel than claimed by
the manufacturer.


Hyundai is not answering questions about this problem, not to me,
not to others as far as I know, and read in this newsgroup.
All there did so far, sending me a letter with the same claims as mentioned
above and saying that this is measured in very "nice"circumstances, without
wind....
There also say that it is possible to use more fuel when circumstances are
worst,
up to 17 % more. If this was the case, believe me I had no problem at all.
But in fact its 100% more.


Course's your right when you say blame your government about the price
of petrol, unfortunately the don't listen to me .
That's why I chose a car with a friendly gas millage.

 

You are really using too much fuel for a car/engine that size. I drive a
2002 Elantra 2L engine and get 12.65 Km/l at a constant speed of 120Km/H in
the highway, the city is a different matter I get only 8Km/l in heavy
trafic.

 

Sorry about that.

That does seem pretty ridiculous for a small car with a small engine.

That's great, but it's not something you can count on to happen with
every vehicle.

I wish I could offer you a solution, but I'm not sure that there is one.
That problems doesn't exist here in the US.

One thing you could try is resetting your ECU. This can be done by
either disconnecting the battery for a few minutes or by removing the
fuse for the ECU. This allows the ECU to re-learn the correct settings
for the fuel mixture and other parameters it controls. Sometimes it can
help with fuel and power related problems.

Welcome to the club.

Or at least you thought you did.
