Kia Sedona Problem Report

Kia Sedona Starting difficulty due to defective anti-theft control module

(41 reports)
Difficulty starting the vehicle may be caused by a defective vehicle immobilizer (anti-theft) control module.
Turn the key and car won't start. No noise at all from engine trying to turn over. All electrical devices work though, radio, lights etc. Usually have to lock and unlock doors to reset anti theft system, then have to hold key in start position for a few seconds before it starts -
Been having problems for last six months. Dealer changed anti theft module three weeks ago. Two day later same issue. Returned vehicle to shop following Monday. Dealer had vehicle two days with no issues. They cleaned terminals on starter and swapped relays. Next day I had same issues twice. Worked fine for 1 week. Then last night issue returned. Sometime have to turn key up to 40 times before it will start. -
car will start sometimes without a problem. suddenly won't start. dealer confirmed immobilizer control mod. -
Last November this happened for the first time - turned key, lights all on, engine did not turn over at all. Dealer said poor connection to starter removed, cleaned and re-secured both + & - cables. Van was fine until mid July. Same problem. Dealer replaced relay, still didn't start, now does intermittently. Dealer claims no knowledge of this easily findable problem with the Vehicle Immobilizer Control Module. Huh? Reports been going on for last 10 years! -
Issue starting mini van. Have repair contract. Kia dealership says they know nothing about this issue and can not fix it until it happens in shop. -
The car starts and runs great but occasionally will not crank. All the proper lights come on the dash, everything else works fine but no crank. It may crank again on the next attemt or not for 10 -20 min. Some blogs say to thump on the relays in the cabin fuse box or the engine compartment fuse box. I have done so and had no luck but then suddenly it will crank and start. I have no clue if the thumping helps or if it is just coincidental. -
van won't start have to keep clicking till it will turn over i believe it's in the theft system because it doesn't work anymore -
Some web site says you have to bang hard and sharply on the area near the fuse box. Sounds weird as a solution, but it works. -
not repaired.weird pain in the neck. -
intermittent for a while now. First work around was taking out and/or pushing in the alternator fuse under dashboard, worked for a while then stopped working. Found work around on youtube where i can go to fuse box under hood, take off grey start relay cap, make contact and car starts every time i do this. But inconvenient and no fun in below freezing temperatures. -
My '06 well-maintained Sedona is randomly refusing to turn on despite having replaced the battery 5 weeks ago. When I turn the key, all electrical systems are fully functioning but the engine is completely silent. Both times this has happened, it has self-resolved after about 20-30 minutes. Alternator checks out totally fine. Dealership stumped. I will be printing out this thread and taking it in to them. Thanks for the help! -
2012 KIA Sedona would crank but not start. Tried the second key provided with car when new. Car started and the problem did not return when using that key. Reconfirmed first key would not start the car. Transponder in first key obviously went bad. Will replace first key at dealer and have it coded to car. -
I'm having the same exact problem. -
Intermittent problem where car runs great but sometimes fails to start. When I turn the key I get silence. Starter does not engage. All accessories still have power. Taken it to two different repair stations one if which was Kia Dealership, but neither could diagnose the problem. Yesterday my wife stopped to get gas and after filling up the tank the car would not start. After about 50 attempts, without rhyme or reason, she turned the key and it started. Don't know if it's the anti theft control module or something else, but we've about had it. -
same problem-wont crank /start at random times-dealer plays stupid like this is the first time seeing this -
Van just want start. All the inside lights work and so do the alarmes, but nothing from engine when i try to crank it up. -

I have had this same problem at least 4 times. Once 2 1/2 years ago I had it towed to the dealership after several marine mechanics tried to get it to work checking out different things. The next day the KIA dealership said it started right up and they couldn't see a problem. Sometimes it will start up after 30 minutes. This time I'm going to have to tow it again but not to the dealership. It's so unpredictable it is aggravating because I can't pinpoint the problem! Maybe this time someone can figure it out. -
Turn key, have power but not starting. Dealer can't find anything on diagnostics. -
