Question about 2004 Hyundai XG350

2004 hyundai XG-350 Check engine light is on and

2004 hyundai XG-350 Check engine light is on and the automatic trans is stuck in third gear. When I turn the key off the dash lights stay on dim and there is a ratcheting noise in the dash. I can reset everything when I disconnect the battery and reconnect with the key in the on position. The check engine light goes off and the trans runs through all five gearings. But the problem begins again the very next time I turn the car off. Unless I reset the check engine stays on and the car is stuck in third. Also battery drains because dash lights don't always go down. I checked fuses under the hood in the fuse box near the battery but everything ''looked'' ok...no obvious burnt fuses. Help!

I'm. New to this, but we have the same exact problems with our 2004 xg350l. I got the car to quit throwing 3rd gear and 4 other coded and having to unhooking the battery to reset. I first pulled the courtesy light fuse and the only light left on the dash was the trunk hood open light (while shut). Drove for a week like that with no problems. Yesterday I also pulled the Milagros computer and radio fuse ( all one fuse- listed ad radio). Now all lights offoff on dash. Most or all problems are from radio I think. All is well now but very quiet. Lol

Sorry Peter I do not have a solution to your car problem, but I also own a 2004 XG-350 and the SAME EXACT thing is happening to my car right now, crazy huh. Pretty much started out of nowhere...the boyfriend is going to go try the leaving keys in ON position and reconnecting the battery. Did you happen to find out what was wrong with yours, thought maybe if you did it would help save me a step. Praying nothing to serious. Hope you got your car working well again!

Thanks,
Nikki

    We have 2004 same thing, we wound up pulling the radio fuse and courtesy light fuse ( obvious. Short in in radio?) All problems went away. But the molar compurt is also off.

Put it on a lift & have to either support the engine all

Certainly not a home driveway job & a dangerous one

Locate the starter


The starter motor will engage the gear in the transmission bell housing to rotate the engine, so it will be mounted on the side of the transmission. The illustration shows the XG-300 and XG-350.

Sudden aceleration


I also own a 2004 XG 350 and am a Plaltinum Certified Technician. My best guess would be the APS (Accelerator Position Sensor) malfunction. However, if the malfunction lasted long enough, the "Check Engine" light would illuminate and set an APS code. Best advice -- have it properly diagnosed by a Certified Hyundai Technician (there just might be other/pending issues).

Trans drops into 3rd gear won,t shift to 4th


DTC P0734 is "4th gear incorrect ratio" - that's your torque converter 'LOCK UP Clutch" It's worn out (or you're using the wrong Trans Fluid required by Hyundai - SPIII OR Both). The P1624 is simply the Trans Control Unit (computer) communicating to the Engine Control Module (ECM computer) MIL - on request signal to ECM = asking it to turn on "Check Engine" light. MIL = Malfunction Indicator Lamp. When the torque converter 'lock up" clutch slips or doesn't engage, the trans automatically returns to 3rd gear and stays there (it's called 'fail safe' mode) until you cycle the ignition key, then everything resets until the malfunction occurs again.
You'll need to have an AT (Automatic Transaxel) tester hooked up to verify this. Hyundai has a Service Bulletin specifically for "gear incorrect ratio' codes. If when you changed the trans fluid, was it done at a Hyundai Service Center? If not, someone may have installed the wrong fluid.

sorry to say trans is fried.
Consider a used trans from the bone yard
or a rebuilt one.
An independent auto shop is likely to give you a fair price!!!!!!!!!!!!!!!!!!!
