I have a 2003 Sonata. In my car, all four doors unlock with the key regardless which front door is unlocked with the key. If the fob is used to unlock the doors, they'll automatically relock if the driver's front door is not opened within 30 seconds. If your 2000 Sonata does not behave similarly, I suspect one of two problems with your onboard theft deterrent system:
1> the logic circuit of the theft deterrent system is merely "confused" and may need to be reset by disconnecting the negative lead of the car battery for several minutes (Record the radio station presets first - they'll need to be re-entered afterwords. The automatic transmission's computer control module [TCM] will also need to "relearn" your shift quality preferences over several weeks of routine driving since Hyundai automatics customize themselves to user preference - aggressive drivers get more solid shift quality, while gramma/grampa drivers get gentler shift quality. My transmission's shifts often range from exquisitely gentle to undetectable so you can guess which category I'm in. The next owner will establish his/her own preference over several weeks behind the wheel.)
2> the logic circuit of the theft deterrent system is defective if it fails to respond to disconnecting the negative lead of the car battery - so there is risk of further trouble by disconnecting it entirely. It's your choice whether to proceed - you may improve things, further screw things, or the current situation may merely remain where it already is. In any event, even if you elect to do nothing, when you eventually have to replace the car battery, you'll find out one way or another.
#1840 of 3234 2000 Sonata subframe rust
Jan 19, 2007 (12:42 pm)
I own a 2000 Hyundai sonata with 80k miles and have had to replace the front sub frame due to significant rust. The rust actually broke the control arm completely off of the car. I have filed a formal claim to Hyundai and it has 2 months and they are yet to even to respond to my letter, even with weekly calls to Consumer affairs.
I also have replaced both my rear wheel bearing twice since I've owned this car.
The transmission speed sensors have also failed twice. The last repair cost $500 for the dealer to repair.
Overall this car has been dependable, however, I find it hard to believe that Hyundai is so willing to tell me that the frame rust is acceptable. I believe this to be a significant safety issue and found several online entries in regards to the same situation.

Problem could be as simple as getting the tires balanced, also the least costly. Other possiblities could be or a combination of bad tires, bent rims, bad tie rods, ball joints, wheel bearings, steering rack, motor mounts.... Find a good tire shop/repair shop to investigate it. Most likely just need the tires balanced which is a few bucks a tire.
#1844 of 3234 2000 Sonata engine noise.
Jan 31, 2007 (11:43 am)
After start the car I feel the engine noise was so loud when the car was cold,but when the car becomes warm, the noise will become small. Does anyone can help me?
I checked it with dealer, they asked me to change the air flow sensor, it will cost $400. What if it dose not work? Should I change the O2 sensor too? Or change the car.
#1845 of 3234 Nitrogen filled tires
Jan 31, 2007 (1:54 pm)
Just had rountine 12,000 mi service today.
I took a shot on the nitrogen (nitrofill brand) in my tires, cost $35 for 4 tires. Supposed to be good for 18 months. Supposedly maintains tire pressure better, increasing mpg and tire life. A tire filled with compressed air loses 1 to 3 pounds per month due to "permeation" they claim. In the event of a flat tire, like caused by a nail, they will refill at no charge.
Does anyone have experience with nitrogen filled tires? If so, what was the experience; good, bad or no difference. Would you do it again? I thought I'd give it a try for only $35, plus there is a 90 day money-back guarantee if not satisfied.

Because of the molecular structure of nitrogen (so I've heard and read) they will not lose pressure like regular air (especcially as it gets colder outside). Race teams use nitrogen in their race tires; also there is no moisture in the the nitrogen. I want to switch myself. Hope this helps

I buy my tires at Costco--they include nitrogen inflation in the price (along with road hazard, mounting and balance, and lifetime free rotation). Just FYI. I do know that some tire stores around here are charging $20 per tire for nitrogen, believe it or not.

On my 2007 Sonata LTD
Re:creaking seat. Both my seat backs creaked: driver's seat worse. Dealer took off seat back and greased rubber guides for headrests. It fixed the reproduceable portion of the creaking. Now creaking (much less of it) only occurs randomly in start-up or stop. Can't make it creak by moving weight. Frustrating, but minor.
Re: sunroof creaking/squeaking. Dealer fixed mine by lubing the weather stripping. I'm guessing this will be temporary, but am hopeful I'm wrong.
Re: transmission lag. Seems just to be a slow engaging trans since all I've talked to have same. Anticipate the shift or drink less coffee.
Glad to say I haven't experienced your other problems.
