Sonata NF (2006-10) :: Engine Clatter Loudly When Starting
Nov 23, 2010
My 2007 V6 Sonata Has a very loud clatter when I start it. It will last anywhere from 2-5 seconds then it usually goes away. It almost sounds like a baseball card hitting the spokes of a bicycle. It's within warranty and last time I took it to the dealer they first claimed they couldn't hear it. Then they changed their story and said that it was the belts warming up, and they said this is a perfectly normal sound for Hyundais to make. My fiance's family has owned 3 Hyundais and they have never had such noise come from any of there vehicles. Both of my other cars never sound like this.

Last Thrusday, my wife couldn't start my Sonata 2010 with 30,350 miles on it. It just clicked and sounded like a dead battery. She had to get a jump start through Hyundai road side service.
I change the battery yesterday (it only had 225 cranking amps) and immediately strange things started happening: lights flickering, engine surging, hard starting, not starting just clicking, gauge lights blink strangely at startup and when switching off ignition, not remembering odometer settings (I set my odo for MPG).

Is there a replaceable bulb for the check engine light? Mines stop coming on when starting the car. I think that's why I failed the emissions test. I didn't check with the attendant in the office to get an explanation.

My 09 Sonata LTD V6 was sometimes idling erratically (revving and slowing) after starting a cold engine. It never happened in the previous 3 winters I have owned it. I took it to the dealer for service and they said an ECM update was just released, described on the invoice as "TSB 10FL002 FOR COLD START ROUGH IDLE".

I have a 2007 GS350 that seems to "clatter" when I start the engine after it's been sitting for awhile. The clatter only lasts a couple of seconds but it's annoying....sounds like metal on metal. It does not happen when engine is cold or should I say first thing in the morning. It happens after the car has been driven, sat for a few hours and then the clatter occurs when I start the engine. This started a couple of weeks ago....I have 29,000 miles on it.
Took it to the dealer last week, the service rep told us that this is somewhat common and is due to the high pressure direct injection system on this particular engine. He also said this started when they switched from the GS300 to GS350. I'm wondering why it never happened before. The service rep said there's nothing they can do about relatively new Lexus with relatively low miles.
I've always used premium gasoline, got all my oil changes and maintenance done at the Lexus dealership thus far.

Ford E150 Conversion Van 1991, V8. Replaced spark plugs, wires, fuel pump, fuel injector, cleaned gas tank, replaced gas. Ignition turns and starts but sputters loudly and stalls soon after. We've tried just about everything but it won't stay running.

Usually in the morning after starting the car, when I put the car into reverse the car stalls. I start it up again and it works fine. It has been doing this for a few months. When I went to get oil change they said I needed to replace battery so I did. Problem is still there. It has done this twice when I try to take off from a red light. I have no check engine lights either. My car has 105,000 miles but cannot really afford to buy a new car at the moment.

I have a 2010 Sonata GLS that isn't starting. I have full battery and plenty of gas. It doesn't click or anything, but all of the lights and electrical equipment work fine. Is there a common problem with this car that causes it not to start?

OK, so I was gone for about a week and my Sonata's been sitting in the basement the whole time. When I went to start it this morning, the starter spins for about two fires then stops. I release the key, try again and it's fine. Once I got to work, I killed it then started it again and it was fine. I'll be heading home in about 30 minutes to see if it does it once again. It shouldn't be due to the cold; it's about 50-60*F in the basement. It turned over just fine, so it wasn't battery or power related. I'm hoping it was just some kind of fluke, but I'm also paranoid after seeing the recent surge of Sonata problems.
Oh yeah, and last time I went on a trip both my cars had problems. The Sonata had a leaking tire and the Jeep had a failing alternator. Now my jeep gets backed into while at the parking lot and my Sonata doesn't start the first try.

I have a 2010 Sonata GLS and it has a starting issue. When you turn the key I have power to everything like dash, radio, lights etc. but it doesn't start. No crank, no clicking, just dead. I have checked the battery cables, battery posts, ground, starter cable. I kind of got the impression from reading other posts that it may be the starter or maybe ignition switch. I have replaced the starter once before but I'm wondering if you all think it's possible to be the ignition switch? If it was the ignition switch would the symptoms I am having be adding up? I guess what I am trying to say is if it was the ignition switch would you still have power to everything like the dash, lights and so on and the car not start or would there be nothing at all (dash lights, radio, headlights) in addition to the car not starting when you turn the key?

I need to replace my girlfriend's starter on her 2006 Sonata 3.3 V6. Her car is having the intermittent starting thing that i noticed some others are. We've already replaced the battery and the starter relay. The relay worked for a while but the car is back to having issues intermittently again. I figured I'd replace the starter now(with a new starter solenoid on it). Also, while I'm doing this I'll check for any loose or rusty grounds.
So, I've peeked under the hood and tried to follow the battery cables to find the starter but I haven't been able to find it. Is it under something? Do I need to remove the battery?

Started my 2010 gen 3 Prius 3 the other day and got a bunch of what I thought was engine clatter and the check engine light came on.
The next time I started it, no noise. Anyways brought it to dealer and they diagnosed it and ordered a new manifold.
The next day when the part arrived, I brought in the car. Talked to the mechanic, a great guy, and he explained what happened. Apparently, the clatter is actually the springs rattling in the clutch mechanism of the starter motor/electric motor and not the valves like I thought.

I have a 2009 Hyundai Sonata GLS 4 Cylinder with roughly 100k miles. The car runs great, shifts great, drives smooth. The only issue I have is starting the vehicle. When turning the key the car cranks sometimes longer than normal and sputters a bit before fully starting. I feel somewhat of a jolt like the engine is firing but its not what I call smooth. The other day it cranked longer than normal started for 1/2 a second then died and I had to turn the key again to start. I have already replaced the spark plugs and air filters. A while back we had the fuel filter/pump replaced but I'm not sure what else to do considering that the car runs fine otherwise. I read something about an EGR valve and maybe it's a vacuum hose?...

I have a 4 cylinder 2009 Sonata with an automatic transmission and it does not accelerate smoothly when starting out from idle. A slight touch on the accelerator pedal causes the motor to accelerate hard as though the pedal was pushed down a lot further than "a slight touch". Is this normal or should this car accelerate smoothly? I am wondering if there is a common problem with either the accelerator pedal sensor or maybe with the throttle servo.

Our 2005 V8 makes an awful noise under acceleration. I think it sounds like a valve clatter, but I think I remember reading it was some part in the exhaust making the noise. I've tried all fuel options to see if it was related to what OCT fuel.
I brought it in for service (5 recalls, nice) and they didn't hear it (of course) until I took them for a ride. The tech said he remembered earlier models having some issue.
I don't buy that it's "Normal" because I don't hear other 4.2 V8s making that noise, and I sure has hell don't think a 45K SUV should sound like somethings broke when it revs past 4K.

My wife couldnt get her 2011 SE to start this morning. It engine turns over strong but it wouldn't start. Brake lights worked. Brake pedal very hard. Tried several times but would not start. Finally I jumped battery just in case and it cranked. Don't know if this was coincidence or not. Car is two years old and only 30k. I checked for interior lights being left on or other things that might drain the battery.
Could a low Fob battery cause this? Brake switch? No codes thrown. Taking in to dealer but wanted to rule out a simple fix.

I have a 2002 Camry V6. It has about 170,000 m on it. When you start the engine, of course it starts at a high idle speed and every time. And, every time there was the ominous clatter of dry engine (probably rod bearings if i had to guess) for a few seconds until there was oil pressure. Probably not too harmful, but it was one of those things that bothers you?! I'm guessing I am not the only one with this happening so that's why I made this post.
The older the engine got the more this bothered me. It's probably "normal", and if you emailed or called Toyota I'm guessing that's what a tech would tell you, but still...to get rid of this clatter I tried every additive there is. Slick 50, Duralube, Marvel Mystery oil (In my view probably useful only for cleaning-do not use in the gas!) STP. NOT ONE of these had the slightest effect on the clatter.
Then I finally tried Lucas oil additive at an oil change. This stuff claims to stick to the metal inside the engine and protect it during a dry start. Well it DOES do what it claims to do! (This is as rare as chicken teeth in the market of automotive products). No more clatter!

I took off my muffler this weekend to see if I could make the rasp sound I get from the back disappear. I managed to make some of it go away by manipulating the heat shielding. However today its been raining all day.. and I have no noise at all.. full throttle.. nope.
Windows open and hammering the gas, even shifting I don't hear it. I remember in my 04 R when it rained the exhaust would have a completely different tone. I wonder why in the rain today in my MKV, I cant hear any engine rattle at all?? strange. Will report back if I hear it tomorrow, or when its not raining.
