XG350 hesitation

On cool morning here in AZ 45-55 degrees, I have hesitation when backed out
of garage andthen put into forward. After that it runs fine. The garage is
probably 10 degrees hotter than outside.
Brought in for first 6 mo oil change, left overnight and dealer says no
problem found. Otherwise graet car!
Any similar experiences. here?
Thank you

 

What is the year and engine type of your car?

 

2005 year and 6 cyl

I don't see any reprograms addressing anything like this.

 

Thank you for response.

I have had the same problem with my 2002 XG350L since I bought it
brand new. Hyundai has NEVER been able to fix it. Much worse when it
is hot out. Feels like an old carbureted car with a bad choke or like
it is running out of gas with no power and then - voom - it takes off
from under you with unexpected acceleration.

 

I have a 2004 XG350L with the same issue. It happens sporadically and at odd
times. Dealer said they can't find a problem I see a trend here with many of
you having the same problem. I don't know if it's outside temp related. I
live in the Puget Sound Area in Washington State.

 

I think several owners have experienced this bogging problem but have
not thought to complain or had the patience to complain and/or bring
suit. Hyundai has acknowledged on my service paperwork that there is a
hesitation problem but has never been able to correct/fix it.
Hyundai's techniocal service made suggestions like "let it warm up" or
"that is normal" in an effort to get me to go away and not bother
them.

If you are having this problem be tenacious in seeking a solution or
getting reimbursed for the problem (lawsuit).

I am positive the problem lies in the drive-by-wire, the programming
and the electronic transmission all working (or not) together. Within
a set scenario (hot outside makes it worse, first started and driven)
the bogging happens, not every single time but it does happen most
often on the first start after a several hour park. This happened the
very next day after purchasing the car and if I knew then what I know
now the car would have been returned to the dealer as defective that
day and I would have refused to accept it until it was permanently
fixed. I assumed (my mistake) Hyundai would fix whatever was wrong
with the car.

They have even had a TSB referrring to this problem. They have also
has several related TSB's regarding the drive by wire programming
issues.

Every other problem I had with my XG that Hyundai "blew off" I was
eventually vindicated by a TSB being issued that spelled out almost to
the letter my original complaint. I would print the TSB and go to the
dealer and present it to them along with restaing my problem and that
would finally fix that problem.

Being a former auto mechanic I guess I am more sensitive to car
problems and refuse to accept excuses such as "that is normal". I KNOW
what is normal with a car and what is not. I am not some complaining
"crank" who just wants to be a pest.

 

I agree with the previous post 100%. I've had my 2002 XG350 into the
dealer so many times for this problem that they have given up. It seems
that either the Mass Airfow Sensor, or the Traction Control System, or
even the Power Control Module is to blame. I get the impression that this
is a design flaw that is not fixable. Hyundai denies that this problem
even exists. Unless a large group of XG350 owners take on Hyundai with
some sort of class action suit, this will never be resolved. There are
not enough XG350's out there for Hyundai to spend the resources needed to
solve the problem.

 

The only thing to do is sue. I have had a lawsuit going (lemon law)
for years now. Even if I lose I have been a thorn in Hyundais side
regarding this Hyundai defect.

 

Yep, that's always a good solution. Makes the lawyers richer, you
poorer and Hyundai could care less.

And what would you suggest I do Matt?

After repeated attempts by Hyundai to fix my car I entered into
discussion directly with Hyundai.

Hyundai asked what I wanted. I told them I wanted my car fixed. They
said they would continue to try to fix it for as long as it took to do
so. I asked how long was acceptable? Weeks? Months? Years? How many
attempts? 3? 5? 10? 100? They would not make any promises. They
refused to replace the car with another or return my money despite
repeated repair attempts with no results and the problem still there.

After months of patience I contacted an attorney.

Tell me oh wise one what you would do so that I may gain from your
immeasurable wisdom.

 

Well, having been involved with one lawsuit in my life (and it'll be my
last), I can tell you that you will be better off trading the vehicle
back to the dealer for one that you like better. Or trade for a
different brand. Sure, you'll lose a little on the trade, but I'll bet
you'll lose a lot less than what you'll spend on legal fees.

I sued, in small claims court, a repair shop who botched a ring and
pinion swap on my 4x4. I sued them for about $1500. They came to court
with a lawyer and I didn't (not supposed to need one in small claims
court, right?). I still won a small judgement of $300, basically, what
it cost to get it fixed correctly by a Chevy dealer, but I didn't get
back anything that I'd paid the original shop (They quoted me $1000 for
the job and then charged me $2000).

However, what happened next shows you how the legal system and lawyers
work. The repair shop owner and his lawyer were livid that they lost
against a lowly citizen. So, they went to the Chevy garage and talked
to their mechanic. I'd written in my statement that in addition to
making loads of noise and running very hot, the rear differential had a
slight oil leak (which it did). When they asked the Chevy mechanic
about the leak, he said he didn't remember seeing a leak and by then the
vehicle had been repaired, including a new pinion seal, so there was no
evidence of a leak. This was totally unrelated to the essence of the
claim, but the lawyer went back to the small claims justice, said I'd
lied in my statement, and convined the justive to file perjury charges
against me! This is a fairly serious offense which can bring jail time.
The lawyer knew full well I hadn't lied, but she also knew that I'd
now HAVE to hire a lawyer to defend myself in county court against this
charge. I ended up spending $3000 to get the perjury charge dismissed.

You do the math. Tell me who won...

Don't believe me though, forge ahead with your lawsuit, but let us know
at the end what the final accounting is.

In my opinion, the best thing to do in a case like this is what I did
when Honda screwed me over on an Accord 22 years ago. Never buy another
product from the company, and tell everyone you come across about your
experience. If Honda had treated me right, I'd have purchased at least
four more new Honda's in the intervening two decades. And I know that
I've personally convince at least two other people to not buy a Honda.
That has cost Honda more than any suit I could have filed and has cost
me virtually nothing.

I am suing under a lemon law. I setup the lawsuit with my attorney as
follows: if I win I get my money back and Hyundai pays my lawyer fees
and all court costs (my attorney felt I had a good enough case that he
took it under these conditions). If I lose in court it costs me
nothing, my attorney absorbs all his fees.

If I lose the case I will trade the vehicle in on a new car from a
different manufacturer.

Mind you, I don't hate Hyundai. Any manufacturer can make a bad car
(look at Mercedes). I just wanted them to own up to the defect and
make good on it which they refused to do even after the defect was
proved to them.

I have since found out Hyundai and Honda both fight tooth and nail in
court to NEVER give back money on defective cars. Toyota and a few
other manufacturers work with you to resolve the case before it ever
reaches court.

 

Well, I never tried to sue Honda, but I had a lemon 84 Accord that they
certainly wouldn't stand behind. That was my first and last Honda.
There are simply too many options available nowadays to buy from any
company that won't stand behind their products. Personally, I think not
buying their products is far more effective then suing them, but YMMV.
I'll be really surprised if your lawyer keeps this case on the basis you
describe above after several weeks of time and several appeals.

Good luck!

Matt
