On this website you find fuse box description for Hyundai Elantra (2008) http://www.autogenius.info/hyundai-elantra-2008-2009-fuse-box-diagram

It's not something you can fix yourself - it typically requires special tools and a very specific checklist of things to check in a special order. Driving with the ECS is no more dangerous than driving in a car made before 2005. It simply means that it cannot automatically correct things like driving to fast into a corner or slipping on ice. If you stay out of the "pushing the limit" type driving and treat the car as if it didn't have any kind of electronic nanny controls, you should be fine.

Most vehicles have 2 fuse boxes. One under dash and one under hood.

it sounds like your describing a leak. Unless you have several expensive air conditioning tools (leak detector, voltmeter, ohmmeter, guages etc or know someone who does ) and a fair bit of troubleshooting knowledge. Your best bet is to take it to a mechanic that your friends can recommend. Ask for an estimate before any work is done. If the price sounds too high, get another estimate. Ask how long the work is warrantied for.

The "EPS" stands for Electronic Power Steering. There are a couple Technical Service Bulletins related to the EPS system published by Hyundai. The only way to find out if any of these bullitins apply to your problem, you must FIRST scan your onboard computer network to gather the fault codes that set when the system turned the light on. Then again, there may also be a problem that is not addressed by ANY of the bulletins.....Proper diagnosis required.The same thing applies for your Check Engine light. There are currently over 600 possible reasons why the check engine light could be coming on in that vehicle. Many of these possible faults can cause your engine and transmission to go into "reduced power" or "limp-in" mode and cause the symptoms you are describing. The ONLY way you are going to find out which possible reason is causing the light to come on is with a computer network scan....Unless you really want to work your way through over 600 "GUESSES".

Sound like a possible with the shift linkage; are you make some job there or adjustment will need.

you can always try to disconnect the battery for a minute or 2 to see if the radio will reset. otherwise if the controls wont respond the radio itself will need to be replaced or sent for repairs

esp light is for your electronic stabilization system, if the light is on while driving, there is an issue with the system and needs to be tested to determine what is wrong

The display dirver has malfunctioned. Proper fix is replacement of audio unit/head

The most widespread Hyundai recall, affecting up to 531,894 2005-2008 Accent, Azera, Elantra, Entourage, Santa Fe, Sonata, Tucson, and Veracruz models, is NHTSA Campaign 09V122000. It is focused on a malfunctioning stop lamp switch that may prevent brake lights from illuminating when the pedal is depressed (the same switch may also cause them to stay lit after the brakes are released).Owners of affected vehicles may contact Hyundai Customer Service at 1-800-633-5151, call the NHTSA Hotline at 1-888-327-4236, or visit SAFERCAR.GOV

disconnect the 2 audio fuses and wiat 5 minutes with the ignition key off, insert both fuses, then turn the key on. if it doesnt eject, it probably has an internal defect and will need to be repaired.

RECHECK MAKE SURE ALL VALVE COVER BOLTS BEEN REMOVED. LOOK AT THE NEW VALVE COVER GASKET COUNT BOLT HOLES IN NEW GASKET IF YOU COUNT SAME AMOUNT BOLT HAS BEEN REMOVED. VALVE COVER STUCK TAKE A RUBBER HAMMER TAP VALVE COVER TO BREAK THE SEAL.DONT PRY VALVE COVER YOU WILL DAMAGE VALVE COVER AND SEAL SURFACE CAUSING YOU TO GET A OIL LEAK.

welcome to Fixya

Electronic Power Steering (EPS). This means that there is something wrong with the part or the sensor only. It would be better to use a scan tool and get error message for us to be able to determine whats causing the light to ON. Here's an article for the EPS.

Thank you for using Fixya! If you need further help, reach me via phone at https://www.6ya.com/expert/elixirjose_00375ea24bd8141b

Your XM radio may still be under warranty. Sounds like your Set Top Box is faulty/malfunctioning.
Contact your nearest/local Hyundai Dealership Service Department and ask the question. Be sure to have the VIN ((Vehicle Identification Number) handy.

Sometimes (few) a fault in the wiring loop causing it to short on the steering column and turn on EPS (Electronic Power Steering), check it and scanned for know if some additional fault code is stored there.

Keep us updated.

Go to www.hmaservice.com and register your vehicle by VIN #..
you'll then have access to wiring diagrams, shop manuals,
service bulletins, illustrations, etc.

Most definately your tire. Out of round and or balance or tire defects cannot usually be detected visually. I would take it to a reputable tire store for inspection. Could be a bent or warped rim if you have run over a curb or through a big pothole, etc. They should be able to tell you if one or the other is defective.

The filter is inside the transmission case & is not serviceable (does not require replacement/service).

your motor could be bad you could have a bad fuse or there is something in the line or there is something in the sprayer head. if you listen around the sprayer motor you should be able to here is it is working or not if it is working it is probably something in the line or sprayer head if it is not working than it is either a bad motor or it isn't getting power if the motor isn't working I would start with the fuses.
