Hyundai - Sonata :: 2006 - Headlights Flicker On And Off And RPMs Shoot Up
Sep 1, 2013
I have a 2006 Hyundai Sonata that in winter does very strange things, almost ghostly. While driving, headlights flicker on and off, the dash abs and esc warning lights go on, and rpm's shoot up and stay there as if it downshifted by itself. I have to pull off the road and turn the car off.
Further, three different times I shut the car off and then nothing would work, including not being able to start the car. After it sits a while it then seems to reprogram itself and works properly.
I contacted Hyundai, and they only said bring it in and pay to diagnose it. But there appears to be no fix, as many have reported electrical problems for this model on the internet.

I have a 3.3L 2007 Sonata. Within the past month, after first turning it on in the morning, the RPMs shoot up to about 1400 and slowly come down to normal after about 5 minutes. It does this in park and neutral, when I put it into drive it goes down to normal. If I drive it for a mile and put it back into park and neutral, it idles at a normal RPM. If I turn the car off for ten minutes and start it up again, it idles normal at about ~850 RPMs.
After doing a bit of google research, a lot of sites say that this is a normal thing for a cold engine to do. However, the RPMs have never gone that high previously. The check engine light hasn't come on.

I had to stop quick today. My ice water spilled into the gear shift lever. A mile down the road my rpms went up high and the car barely moving.

After I fill my 6 cyl 2004 Hyundai Sonata (280,000 km), the engines starts, then stalls. I can only get it to work by keeping the accelerator pushed to ensure sufficient rpm's. If I remove my foot from the accelerator, the rpm's drop to zero.With the engine revving, I put the car in drive and 'lurch' away from the pump. After that, everything is fine. It starts up properly … until the next fill. My mechanic is mystified and I am frustrated.

Headlights will not go off no matter what the switch position. Can only get them off by pulling the fuses

So the other day I was driving to my storage locker about 30 miles away. All of a sudden my rpms would shoot up to 2000 rpms then back down to 1500 . Slowly they would go up higher every time. On my way back I was about 2 miles away and I lost 3rd and 4th a presume. I would be going 20-25 and it felt like it would be shifting up to third but would shift down to 2nd running 3500 rpms. I had to go 20 the rest of the time. Finally I got home and realized my dipstick tube wasn't in the tranny and must have lost oil. So I got it back in and added more. Thought it was the filter and oil so dropped the pan and replaced it. Still nothing.

2010 Mazda Speed 3 ....My car has about 62,000 miles on it and has recently been having acceleration issues. 1-3rd gear seem under powered and what I am giving on the gas does not equal the power that should be coming forth, the RPMs seem to shoot up really high with no power transfer. When i am in 3-5th gear my acceleration is again funky with the slightest touch on the gas again causing the RPMs to jump high with no return of power to actually accelerate. I recently replaced the battery and changed the oil??

I have a 1998 Toyota Camry , whenever I start it after its been sitting for 3 or more hours the rpm's shoot up to2,000 and stay there for 3-4 minutes straight, if I hit the gas they don't go down, if I turn my heat on they come down a little bit.

When I start my 2003 Escape 3.0, the rpm's shoot up to about 3000rpms. After a few seconds they drop to about 2000 and slowly creep back up to 3000. When I put in gear, I don't even have to step on the gas and my vehicle goes. It maintains between 1500-2000rpms as I'm driving. When I come to a red light or stop sign, it lurches like it wants to go even though I have my foot on the brakes. I've replaced the IAC valve, TPS, had it checked for vacuum leaks, PCV valve replaced. I'm at a loss as to what it could be.

2006 Hyundai Elantra. RPM's go flying everytime it's fired up. RPM's will drop once it's put into gear, reverse or drive and runs just fine afterwards. If it's not affecting how it drives should we just let it be? Is there anything to be concerned about?

Recently I have noticed that when on a tune other than stock I am getting a surge at idle - my RPMs drop to around 621-630 then shoot back up to 660-675. On my stock tune my RPMs stay around 640-667 and don't cause the surge (felt as a shimmy so to speak). Is there anything else that causes a similar symptom? I attribute it to tuning due to it only happening when running anything but stock but could be wrong.

My 2005 Elantra has no running lights, a/c won't come on, dash lights don't come on, and lights flicker on the dash when I have started the car and it has been on for a few minutes. Where I can look for a short or possible main fuse box in the engine? All the fuses in the interior box are fine. Headlights, wipers, and radio all work fine.

Every now and then my headlights dim, flicker, and then go out. They will come back on only to do it again a few seconds later. It's only happened 4 times. After the first three times (all while driving on a freeway that was having work done making it but bumbier than usual) I took it to the shop. He tested the electrical system and could find nothing wrong. While he had my car he replaced a bad spark plug that had come off and fried a spot on the boot. I know the two things aren't related but the lights were fine for the next two months. The other night they did it again while I was on a very dark back road and it scared me to death. This road was a little bumpy and very curvy. I've had the battery and alternator checked and they are both fine.

I have a 98 Accord LX with 2.3L 4 cyl. with 356,000 miles. It looks and runs fantastic. However, lately, both the headlights and heater/blower/control console -- either will not come on even though the engine is running or sometimes flicker while driving down the road. When I type in "98 Accord no headlights" it gives me a couple topics about headlights then jumps all around and even goes to totally different car manufactures. I'm sure out of 305 pages of replies there are lots of readers that have had similar issues. I installed a new alternator about 3-4 months ago.

I drive a 2006 Hyundai Sonata 4 cylinder (2.4) that has about 81,500 miles on it. Recently, I notice front-end squeaks when turning either hard left or right while traveling 10-15 mph or more. There are no squeaks on straight-away driving. The squeaks are not loud - more like muffled squeaks - and occur 1-3 times per occurrence. I asked several people at auto parts stores. Most tell me that it is likely my tie-rod ends which have no grease fittings. One or two people have mentioned CV joints but I discount this as there is no damage to the boots and I do not get the tell-tale clicking noise on turns.

I bought this truck new. A few years ago while driving to work my headlights began to flicker. The problem became intermittent and didn't seem to affect my fog or high beam lights, just low beam. That night I tried to find the loose connection with no luck. The truck had 35000 on it then. To play it safe I went ahead and replaced the light switch. The next day the problem went away but came back about a year later and again the lights would flicker then stay on for a while and start again. The problem would disappear for a day or two and start again. I put this truck into two Dodge dealerships and they couldn't find anything. The problem went away for about three weeks and came back. This time I put the truck into a different non-Dodge repair place and after three days they couldn't find anything after pulling various connections apart but said the likely cause is probably one of two electronic parts.
One was about $300 and the other was just over $500 and they were nonrefundable because they were electronics. I went ahead and went the cheap way. After a little more then a year I noticed my headlights went out for about two seconds and came back on. It didn't do it anymore that night. Then about a week ago I got about a mile from my house going to work my headlights started flashing as if they were sending "morse code" in 5-10 second bursts. Again, hi beam and white fog lights are unaffected. I've since parked it. I've looked to see if there were any service bulletins, recalls, etc and found nothing. I'm finding it really hard to believe that my truck is the only one doing this.
