My Hyundai Sonata won't start, everything comes on when the key is turned but no starting action occurs. Sometimes you can get it to start by rotating the key in a circular motion but not lately.
Car won't start and no noise but everything else comes on. Been to a mechanic who did a lot of work but it did not change the fact that the car sometimes won't start. Any ideas?
It sounds like the contacts at the end of the ignition are not closing. They could be dirty. They could be worn. They usually send a signal to a relay. That relay may be bad or have a bad connection. -- You need a schematic, a meter and a knowledge of electrical circuitry to trace the signal through the wires.
Also if/when you get this fixed, if you have 20 keys, a flashlight and a charm on your key ring I recommend you lighten it up. I have had several experiences from ignition switches being ruined that way
Is there a switch on the clutch pedal if so could it be that
I have a 2011 Sonata with a key ignition. I have had problems with the car starting for 18 months. First the Hyundai mechanics told me it was because the tires were not perfectly straight. Hah. Now the light does not turn on to indicate it is in park and until I jiggle the shift until the light does come on it will not start. Was in the shop for a week the first of July and worked for 2 weeks and now in the shop again.
My 2009 Sonata has been "perfect" with no issues. I took it in to remedy to the two recall issues today (brake switch and crossbar); tune up (spark plugs and fuel injector cleaner); and coolant flush. After 3rd start going leaving dealership, making a stop on the way home, and one more start to go back out for dinner, there were no issues. I brag on m car all the time. I love it. When leaving the restaurant, my car wouldn't start, not even turn over but I did have lights on the dash. Car was in park but we moved it in and out of gear several times while trying to start ( my husband said it had been acting up for about a week and shifting and going back to park allowed it to start.) Called service manager and he told me to check battery connections and voltage even though Hyundai had just performed their several point inspection. The car did eventually start before I had to call AAA. Started fine several more times this evening but I'm untrusting now. I don't want to get stranded, especially this time of year. I'm willing to look into the key ignition idea and welcome any others. Where do I start looking at the contacts? Will I need to remove part of the dash or can I crawl up under it?
I'm having similar issues on a 2006 Sonata GLS 3.3L. Took it to the dealer who's mechanic said it was the ignition switch. They wanted $350 to for a $25 switch and 5-10 minutes labor. I changed it out. No change. The car starts consistently if I turn the key and put it in neutral so I'm not worried that I'll get stranded. This also tells me that it is not a battery or starter issue. I believe it has something to do with the shifter contacting the Parked position sensor. That's next. Here is the website for the ignition switch if you want to try it. It is a common cause for this type of issue if your car doesn't start in Neutral as well. http://www.carid.com/2009-hyundai-sonata-steering-parts/item-8777192.html
Also have the 2006 V6 and when the car was around 5 years old, I had the same problem. You turn the key and nothing except the radio and lights but no cranking. It happened every few months. It has been getting worse now. The car is now 8 years old and it happens almost every day. The circuit involves the security system and park/neutral sensors besides the starter, relays, fuses, etc. No one has figured it out and I usually keep it running for short errands. Some of the tricks I have tried are cycling the door locks, trying to start in neutral, and if not then back to park. Up until today, it was totally random if it starts. I had been reading up on similar issues with newer models with the push button start. That problem seems to trace to a bad or misaligned sensor on the brake. It would need to be pressed all the way down to start. Using the same idea on my 2006 thinking the brake petal could be related, I would hold down the brake petal. It has started even time in the last day. A small sample but I hope I am onto something. Previously, I just waited and tried different keys and prayed.
I am having the same issue with my 2009 Azera. First we would make sure the tires were straight(doesn't matter anymore), then we would start in neutral (doesn't work any longer), I will try cycling the door locks. This is clearly a Hyundai defect.
Ultimately, this turned out to be my starter. It finally wouldn't start one day when I was 1.5 miles from the dealer. I had it towed and they were able to take care of it for me right there and then (at about a $400 price tag). At least it's done and I don't have to fear being stranded any longer. I still love my 2009 Hyundai Sonata.
