I was in for a few minor service items at the dealer a couple weeks ago and they mentioned that there was a recall for a reprogram of the computer. Something related to the transmission (but didn't get any details). They did mine - might have helped with a little of the lag I was feeling from 1st to 2nd. But that could be from readjusting the fuzzy logic after the reset too. There was the annoyance of losing all the radio stations, clock, seat settings, etc.

#1-Cruise Control. Though I only notice the excessive downshifting on even the slightest inclines and the delayed upshift at the crest (up to 30 seconds), while on road trips, it is still annoying. I found that by tapping coast or accelerate quickly, I could force the shift back to the appropriate gear. No worthwhile input or solution from the dealer.
#2- Hard shift from 2nd to 3rd. This has always been very intermittent and when it flared up, usually lasted the better part of a day and then went away for weeks or months at a time.
#3- Shuttering from 3rd to 4th. Also came and went under varying conditions, speeds, types of acceleration, etc.
After reading earlier posts and follow ups about TCM reflashings, TCM replacements, trans. replacements, contaminated fluid replacement and problems still remaining, I decided for the severity of my symptoms, it probably wasn't worth the hassle of dealing with incapable or unknowing service departments and the frustrations that go along with that. I drove on, really enjoying my car (for the most part). Then recently, I noticed something new. Sometimes when shifting into reverse from park, there seemed to be a delay as long as five seconds before noticeably engaging. When it finally did, it was a very hard jolt into gear! At first it was only once in a while, but increased in frequency and severity over a short time. This was something new and in my opinion, more of a safety concern than the other things I had noticed. I took it to the dealer and they talked of a reflashing which I had been hearing about since last summer here, as being new and hopefully a possible solution for these problems. I was skeptical, but they reflashed and told me to pick it up. They could not get the "jump" into reverse to occur for them however and said to take it and see if it was still happening. It was so I took it back and now they have a "flow chart" from hyundai outlining diagnostic procedures to follow. They have checked pressures (supposedly OK). TCM readings of some sort are out of specs, so they are replacing the TCM and then they'll take it from there. Maybe they'll just have to replace the whole transmission if that doesn't fix it. I have mentioned the contaminated fluid theory to them several times, but they don't seem to know anything about that, and who knows where that will go.
I really like my XG, but to have this sort of mystery problem on a car with so few miles worries me a bit. I am curious if any others who might have had similar problems have had any solutions come up that may shed some light on mine. Thanks for any info that might be of help.
Which hyundai dealer is this?? VIN?
I have some transmission abnormalities that have been documented here by others and now, something new that has me concerned. I didn't mean to offend with improper terminology, only share my situation and maybe get some feel for whether or not others have had the same or similar problems, and if they have had any luck resolving them.
Ever so humble.......Peace!
FYI, I just returned from the dealership and the service guy (the one that rights the tickets) also could not get the car to start. Sorry to blow your theory on it just being me. As I've said all along, the service guys have been great (Covington Pike, Memphis) and I have only praise for them. The problem stems from the fact that the electrical failure appears to prohibit the on-board computer from giving them the failure codes necessary to diagnose the problem. Again, they have now experienced the same problem first-hand.
weird kind of x-files type genetoc problem like an anti-matter spastic nerve that blows out electronics or prehaps anti-ionic high capacitor brain discharge syndrome. If not, its probably just a problem with your car & you are definitely not at fault!!! I repeat...unless your stereo &
TV's, computers are also mysteriously blowing out your probably just fine...My wife tells me
that the X-files is all based on true stories but am somewhat skeptical myself.
@34,000 miles - front rotors warped, resurfaced
i took to dealer for when coming to a stop, fairly quick, same pressure on foot pedal, feels like the car wants to keep going, sumtimes actually moves a few inches, w/ brakes on....
dealer says it has to w/the ABS...that it is NORMAL....i will see how bad this gets and take it back in.
also put 225/45/17 rims and toyo tires..keeping 37psi in all 4 tires......after 40mph the STEERING WHEEL vibrates (shakes) heavly....very annoying....rotated tires and did a balance to correct problem DID NOT WORK....anybody know what i can do to correct this?
I'll post again when I see if the new transmission helps. Good luck Cody and let me know what if anything you find out.
is there anything else i can check or do to TRY to correct this problem??...its VERY annoying...maybe the rim or rims have already been bent..i hope this is not the case...
since the tranny has been replaced @ 1600 miles..havn't had any problems w/it now @ 35k miles
..it could be that the rings that center the wheel aren't centering the wheel properly... if this has been check out.. then the last thing you can conclude is that your wheels are bent/out of round due to hitting a pot hole/bump
It is interesting to note that the transmission does not misbehave (shudder while shifting or clunk into reverse) when the engine is cold. This abberant behavior occurs only at normal operating temperarture, possibly substantiating the case for the diagnosis of bad transmission fluid. I'll let you know if the dealer is able to remedy these conditions when I bring the car in for its' next warranty service. However, given the prevalance of this condition noted through this forum, alone, Hyundai needs to pay closer attention to its customers' and not merely dismiss their concerns. Reliability of Hyundai products is still suspect, (poor-near poor) according to the latest Consumer Reports Auto issue. There are many acceptable alternatives to purchase, possibly of even greater value given the recent price increases of new models selling at mark-up on the East Coast.
I'm a new XG350L owner with less than 200 miles. This car is amazing, but I'm confused about the operation of the A/C Mode button. Yes--I've studied the manual, but, like the auto seat function, maybe there's something that Hyundai left out.
This morning, 41 degrees F outside, I hit the Auto button and the light in the button over "A" comes on. I hit the switch, but the light stayed on. Then, as I continued to drive, about 3 minutes later the light went out.
Do I have gremlens, or, as I suspect, is the system smarter than me?
Thanks for any advice--I'd love a thorough explanation of the fresh air/recirc/auto recirc function.
O=Inside air
AUTO...outside air first until interior is "COLD"
as interior is cold enough it shuts out the A mode and keeps pumping until a set limit.. then the fan speed goes down until interior temp goes up again.
Both the A and O lights are off at startup. This is the default for outside air.
Just put back on stock 15rims/tires...Doesn't shake/vibrate now....
I never did get an alignment Yk911 as you said..I conclude this is the problem...
I went to a few alignment shops, they dont have the specs to do it, for this vehicle? Yk911 on your XG only the front needed alignment, correct?
w/36,500miles 01' xg300 ....car is great!
just UGLY!
They ruined it completely!!
The other day, it scared the heck out of me with a bad case of hesitation when merging into the traffic. I don't know why it did that but it was VERY disconcerting. Did anybody else experience this problem and how was it fixed?
I have about the same milage on my XG350L and understand the "grabbiness" you speak of. Sometimes when taking off I am almost thrown back in my seat. Other times the takeoff is relatively smooth.
Have not had any hesitation as yet.
Has anyone figured out the A/C system yet, e.g.: the A or O buttons ?
i'm guessing ALIGNMENT or your wheels are out of round.
the above link are the alignment specs.
when getting your alignment done.. please take it to a reputable shop that does alot of inch up wheel/tire combos, because most shops aren't properly equipped to adjust/correct problems.
When i had my alignment done with my 18"wheels installed, the tech said my toe in/out was out of spec.. as the chamber was dead on(our cars chamber can't be adjusted without chamber adjuster kits).
Now, I have another problem that happened a few times. When shifting from 2nd to 3rd, it seems to slip. At about the shifting point (around 2500 to 3000rpm), the engine will race to about 3500 to 4000rpm (and the car feels like it is coasting during this time) for a few seconds before shifting into the 3rd. Did anybody experience similar problem?
I hate to say it but I am really beginning to wonder about this car.
That might help in any discussion I have with them. Funny situation, this! Had the car out all morning today and couldn't get it surge. :-)
Thanks for your input.
My XG300 has a little over 15000 miles in about 7 months. I have had quite a few various problems, paint, alternator causing engine noise, wind noise to name a few. The engine noise problem after replacing alternator two times and the wind noise after replacing something two times are still with me. I have tried to ignore them, getting used to them.
Now there is another recall from NHTSA that I was notified of by Carpoint. I believe that this is the third recall. This one is about the following.
INTERIOR SYSTEMS:PASSIVE RESTRAINT:AIR BAG:SIDE DOOR
Well, I guess I have been and still am losing confidence in XG300 with yet-to-be-fixed-but-still-bearable problems. Thanks for sharing.
The other recalls were minor and only affected a few cars. One involved the PCM unit being improperly installed on 1963 cars made between 08/2000 - 09/2000. The other one pertained to 3255 cars made between 04/2001 - 08/2001 that did not have the right tire pressure label installed.
Their is an open recall on this item:
My No Charge Invoice says "S100 ECM Reprogram". Took alittle over an hour and everything seems fine now.
William, Thanks for the "heads up".
