You are in the Hyundai XG300/XG350
What is this discussion about?
Hyundai XG300, Hyundai XG350, Performance Mods, Sedan

Hyundai isn't the only auto mfr to be plagued by imperfections in the design of "throttle by wire." I had a 1999 Lexus LS400 that had really offensive problems with the same function. The dealer indicated that many complaints had been received, and the quirks were the "price of progress." Lexus never admitted to the existence of a problem. But watch what they actually DO! It is my understanding that this design concept was scrubbed from the LS430. Will be interesting to see if Hyundai dumps it in the Azera.
In the case of the Hyundai XG350, at least Hyundai has come out with a new firmware program that does quite a bit to improve the situation, even though not necessarily completely "solving" it. In the case of Lexus, they simply stonewalled.
My 1999 LS400 and 1990 LS400 also had ridiculous design problems with the so-called automatic climate control system. This universal defect has been confirmed by me via discussions with other owners on Lexus message boards. Lexus never admitted to having a problem and never solved it. But the system WAS completely redesigned in the LS430, and touted as greatly improved.
My Hyundai 2002 XG has some quirks in the way the automatic climate control works, and I usually end up running the system manually, but the oddities are nowhere near as screwball as the ones in the 1990-1999 Lexus LS400's where, on hot summer days, you ended up cranking up the temp setting to the maximum; even then, the air coming out of the vents was extremely cold and you had to keep adjusting or shutting off air outlets in an attempt to keep it from blowing on you.
There are other examples where Lexus has swept "issues" under the rug. My brother has a GS400 with terrible vibration problems. He has gone to extraordinary lengths to pinpoint a diagnosis, to no avail, and has proved that other cars of that model have the exact same problem. But Lexus stonewalls, refusing to admit that there is a problem, thus guaranteeing that there will be no solution.
It is this type of arrogance on the part of Toyota that creates fertile ground for Hyundai to prosper.

Here's the final outcome... the throttle control was replaced and the main computer (wire control) was reset with the most current firmware/software. I drove the car away from the service bay and within an hour, it was slipping in gear (like the trans plates were not fully engaging) and soon after did the lurching dance from a fresh start. I scheduled another service visit, but before I could get in, the dealer general manager called and offered to swap the car out for an identical vehicle. We made the trade a few hours after. In comparison, the replacement XG350 is a completely different machine. The shifting is smooth as silk and acceleration response is on a straight line with throttle application. I am delighted with the replacement vehicle (although its only two days old) and with the dealership (starts with R in Knoxville, TN). I have to admit that I lost my temper with their service team twice during the ordeal and they responded to my outrage as perfect gentlemen. I was amazed that the GM would initiate the swap, as I know trying to return a lemon to the manufacturer is almost impossible. There are now 6 major car manufacturers in the world, but if Hyundai dealers all operate in this fashion, there will soon be a seventh giant car company. I wish that every car ownership experience I've had over the past 30 years had been like this. Hats off to my dealer and I hope Hyundai does accept the vehicle return to tear down the drive-by-wire system and diagnose this potential safety problem.
Also, if Hyundai folks are reading the forum, there are two improvements needed in the XG350 vehicle. The auto seat adjustment (memory switch) located inside the driver door requires the key in ACC position. But, if your driving partner is 5 ft tall and you are a foot taller, you can't slide under the wheel to insert the key. The seat memory switch should operate with the door open and without key in switch. It would also be nice to be able to use the extrta 12v power supply provided in the console without the key in switch.
#1706 of 2117 discontinued????
Mar 26, 2005 (9:31 am)
I just heard the xg350 will be discontinued for 2006. Will be replaced by a model called "Azera"? Has anyone else heard this?
Mar 27, 2005 (12:59 am)
I haven't heard that the XG350 name will be retired. An all new model is due for 2006 though.

That was mentioned in this morning's Chicago Tribune auto section. I believe some posts back a couple of links to the new XG/Azera were posted. In the accompanying movies I think the name was Grandieur (sp) so Azera may be a US or North America name. Sweet looking car.
Mar 28, 2005 (12:04 pm)
I stand corrected. I admit though that the Azera name is better then XG350. I'm glad Hyundai is abandoning those stupid alpha-numerical names.
#1712 of 2117 New problems with 2003 xg350l
Mar 29, 2005 (9:05 pm)
Well my xg350l is having major problems yes the car has only 13000 miles on it and is still under the manufactures warranty . The ses light keeps coming on and off have had within the last week 5 sensors replaced . Just towed it back to the dealer to know be told the engine has spun the rod bearings . I will need a new engine. So far the dealer or Hyundai is paying for the rental, and the engine and the repairs but I dont think I will be purchasing another Hyundai car. I have taken care of this car even though I was told to change my oil ever 7500 miles I have done this every 3000 miles . My car has only 13000 miles on it and the engine should not be failed at this mileage . I am in the auto repair field so I know sometimes there may be a bad car some one might get, but a engine at 13000miles ???This has left a really bad taste in my mouth with Hyundai cars!!!!!!!!

I can certainly understand your being disenchanted with Hyundai after an experience like this!!
Hopefully, this is an extremely isolated case. I have been reading several XG message boards daily for 3 years now and, as best I can recall, yours is the first case I have encountered of problems inside of an engine, requiring its replacement.
Am wondering if other "regulars" of this board have a similar impression.
My thoughts go to the all-new v6 that Hyundai is in the process of rolling out across several of their models, with several displacements. Considering their huge production targets, if the design isn't rock solid, they are going to have a disaster on their hands!
