Check all your seat belt attachments! This seem to be a leading oroblem with all vehicles that has a few miles on them. All it takes is wasting coffie or soda's into one of those locking mechanisms and it thinks the seat belt is not locked. All these vehicles have seat sensors too! If you sat anything more than 3 to 5 lbs on the seat, it thinks someone is sitting on the seat and the chime will continually go off and drive you nuts. Hope this helps you with your problem Sir

Fix your car right away by clicking the link I attached https://www.reliable-store.com/products/2004-hyundai-elantra-repair-manual

Remove the front and rear sill plates. You can then pull off the middle panel.

This happened to me the other day! My husband took into Kia dealership only to be told they'd need it for a few hours, might have to take the whole seat apart, then resulting in labor charges!
This morning my dad came over with solutions he'd found online involving the use of a broomstick or rake. That didn't work. You first have to slide the whole seat in the forward position, so the metal tracking behind the seat is exposed. Next locate the cable cord on the inside of this track. My dad then took a long, flat head screwdriver, placed it under then cable and pushed it upwards/forwards-which released the rear latches and then I pulled the lever and we pushed the seat out!! Hope this helps!


Slide seat forward so the rear track

Not sure how many miles on your PT,but may be wire bad or not fully seated or bad lug on coil for #3 cylinder.Not sure if crankshaft position sensor would cause only one cylinder to missfire.Just remember that the timming belt needs to be replaced between 75,000 and 100,000 miles.My wife didn't know this.Well hope this helps,and good luck.

if it is any other than the center seat in the rear be carefull first disconnect the negative battery terminal because in this car you probably have side curtain air bags they will go off if seat belt is handled improperly and it will be ugly and expensive with the negative cable unpluged it will not go off. there will be two large bolts and one small bolt behind the garnish that will need to be removed disconnect the air bag sensor by pulling out the black locking tab with a small flat screw driver, pull out seat belt and belt carrier assembly, reinstall the new belt and belt assy, small bolt tighten to snug only a alignment bolt two large bolts torque to 45lbs reinstall air bag wire and garnishes reconnect battery and ps to be extra carefull with air bag sensor by grounding your self to the car can be set of by static electricity has broken fingers this way before.

I assume you've already worked the seat belt end back and forth with force. Did the belt move at all? Did you remove the rear seat bottom cusion from the car? That will give you additional leverage on the belt.
If the belt twisted the last time it was used and then rolled up, you need to go to the dealer or an upholstery shop for help.

it would not hurt to check rear tire wear due to misalignment
cupped tires will cause a faulty bearing type noise or humming.
