Hyundai - Sonata :: 2009 - Loud Screech Upon Startup?
Jul 22, 2013
I have a 2009 Hyundai Sonata which gets a sporadic high screech upon startup. I associate this sound the key left in the ignition after the car has already turned over. It will go away as soon as I shift into drive. Is this the problem with the ignition switch or starter? How difficult is this to diagnose as it only happens on occasion? Assuming it's the ignition switch, might I be damaging the starter if it continues?

I am going to start from the beginning because oftens times we don't provide all of the information that may be pertinent to the correct diagnosis or repair. It'll be kind of lengthy! It all started about 3 days ago when my wife told me that my truck was "shaking." I said, "ok, just drive the car til' I can look at it" The next morning, the I was able to look at the truck. I had a cylinder 8 misfire detected. I drove it for about 1 hour that day to and from work. I did this so I could see what what the "shaking" was. It was actually what I describe as a "shudder."
Anyways, I done a fuel pressure check and all was well. I took of the coil, tested it, it was fine. So, I took out the plug to inspect it. It was wet! Not drinched, just mildly damp. I dried it off, cleaned it off with carb cleaner and it fired right up no hesitation no nothing. No CEL light, no shaking, no shuddering. It ran perfectly normal. I let it warm up to speed and took it for a test drive around about 6 city blocks. All was well. So I took it on the highway for about a 2 mile stretch. I was givin' her some juice pretty hard to see if it would misfire. Upon acceleration I heard a screech. Now this is where it get's interesting.
The screech that I hear, I just related it to the belt because it's done it ALL the time. When I first bought the truck it squalled like a whipped puppy cause of a cheap belt. The good ol' bar of soap trick fixed that! But, ever since then, it upon shifting, or under acceleration it would screech then stop. So anyways, on the highway run, it screeched while I was accelerating. It did this from about 60mph-80mph. I then, turned around and came back home. By the time I got to the stoplight to turn off towards my house my oil light was on and the engine was knocking. Not a tap, a knock.
I slowly coasted home not going over 20mph and pulling it out of drive as much as I could. I get home, and I check the oil and there is nothing on the dipstick! WTF!? I always run Mobil1 Full synthetic and put it 6qts. It doesn't smoke, doesn't leak or nothing! So I freaked out and went and bought 2 qts of Valvoline Hi-Mi and poured it in. It brought up the hash marks and quieted the deep knock. Later that night after work, I done a full oil change and flush and put back in my Mobil1 Fully synthetic 5w20. It now knocks at startup, and smooths out to a tic. Then at idle, it sounds like a light knock. It appears that it goes away upon acceleration.

While driving our car I heard a loud popping sound and had to call roadside assistance. I was informed that the frame had cracked which probably caused the axle to drop. The car is part of a class action suit for corrosion of the frame. Customer service says that they will cover any damages to the car as a result of problems with the frame. If the local Hyundai asks for payment, Should I have the car fixed and submit the bill to the main office for reimbursement?

I recently bought a 2006 Hyundai Sonata 3.3 V6. Had another issue related to the rear wheel, which I fixed. Today, I changed the oil filter on the car (along with the oil). I have heard this engine noise before, but with the cover off it appears a little louder. It’s basically a ‘ticking’ sound.
The engine uses no oil, and has no other leaks. It has some noise on startup for maybe 1-2 seconds (like a loud lifter or something, but it goes away in less than 2 seconds, and at the same time the oil light goes out). I changed the filter today because I was told that a leaky gasket could result in the Filter not retaining oil between starts, causes some minor knock for a few seconds.
But anyway, this other ticking noise seems to be regular, regardless of condition. I have heard some people say that some engine noise is normal for this engine, but how about this?

My car - a 2007 4 cylinder Hyundai Sonata - is making loud screeching sound more than occasionally but not all the time at high rates of speed (70 - 75 mph) and ESPECIALLY when I am exiting the highway to go to the train station and I turn to the left on the exit ramp. Never the right - only the left, and it stops immediately when I touch the brakes.
About 6 weeks ago, I had 4 new tires put on, and thought maybe they were not installed properly. I saw a mechanic today who put it up on the lift and said everything looks in good order and he could not find anything wrong with the driver's side front wheel, which is where it sounds like the noise is coming from. Of course, when we drove around in it, there was no noise. In fact, after I dropped him off and went to the train station it DID make the noise, so I turned around, picked him up and drove back exactly the same way - no noise.
It is a very, very loud uninterrupted screeching sound.

I own a 2004 Hyundai Sonata (2004 Base model L4 - 2.4L 2351cc - MFI GAS DOHC) which is a 4 cylinder and has about 113000 miles. Anyways, about a month ago we had one of our coldest days of the year. I drove the car to work and everything was fine. Then when I left work (it was freezing cold) I went to start the car and it sounded like I started a race car. It was so loud that I thought the car was going to blow up (no check engine light came on). I changed the oil and that didn't work and so I figured it was something with the exhaust.
Then I took it to my mechanic (applause). He said that he was stumped, the car was noisy but he didn't think it was a problem but he said he would try to figure it out. He ended up taking off the timing belt and said that was fine, he said the water pump was good as well. He had a service tech look at it with him and they thought the issue might be the "vibration dampener" or "damper" So they replaced that but it didn't work. He said it could possibly be the motor mounts but he said when he looked at them they looked okay?
I drove it off his lot yesterday and it is quiet when I idle but I can see the steering wheel shaking significantly. Then when I hit the gas it is still obnoxiously loud and with heavy vibration! But when going down a hill and letting off the gas there is a brief respite of silence (still vibration). It is especially louder in lower rpms and sometimes I think I can hear a metallic clanking/scraping noise when I have the times of "silence" but it is very faint.

I hear a loud screeching noise (like a loose belt) when the 2009 Corolla starts cold. It disappears, and when the car gets a little warmer, it's gone. I had the belt replaced, made no difference. Car runs fine, otherwise.

Our brakes sends out a loud screech but only while it's backing up. (78k miles)
Is it time to change the pads?
Should we service the brakes at the dealership or private auto shop?

I just replaced my my k03s with another one with only 20k on it. After I did this, I noticed a loud screech sound when in WOT. The screech lasts a little bit after i left off the gas when revving in neutral. I've been doing research on here, and I've read that it could be a boost leak somewhere or even the turbo dying. The shaft play is minimal though.

I've been experiencing a loud clutch squeal or screech when I first engage the clutch after the car has been sitting for longer periods of time, overnight etc. It goes away after a few shifts and only returns after the car sits for a long period.
I brought it to the VW dealership since I'm still under warranty for a bit. After two visits the have come up with two hypotheses without any evidence. They claim to have not heard it or found anything wrong visually.
1) it could be a rear main seal leak. Or leak from somewhere on the tranny onto the cultch. When I first drive it is burned or wiped away. After putting on the lift they found no evidence of leaks. So hypothesis two:
2) Thy flywheel may be developing a bit of a patina of rust. After the clutch is engaged a few times, the rust is gone and the squeal goes away.

I'm looking to sell my 2009 sonata soon. I had an engine light and saw p0017 a couple weeks ago, accompanied by a tapping noise from the engine that speeds up as the engine does. On Friday I figured I'd take it for an oil change before getting a price on it from carmax, but didn't wanna bother spending a lot to fix whatever was causing the code/noise. My Last oil change was August 2015, 6k miles ago. Jiffy lube said the oil was low and clearly it had been a long time since I had a change (time, yes, but not so many miles, but guilty I guess) so they recommended an engine flush. I said ok. Drove the car home from them and all seemed fine.
Went to drive it Saturday night and it shakes and the lights flicker and I didn't seem to get any power, I was afraid to drive it and wasn't even sure I'd get enough power. My battery does this weird thing sometimes where it's almost dead in the morning (no lights on and no parasitic draw, I've checked) and if I try a few times to start, with each try it gets better until it starts. So I charged it with a trickle charger and tried again but same problem. After this started it was also giving me a p0035 and p0135. I had it towed to a mechanic and they said something big time busted with the motor and it needs to be replaced. He said he didn't even pull it into the garage, he just did something in the lot.
I'm just looking to get it into good enough shape for carmax to give me more than a hundred bucks. I just decided to see if I could hobble it to another mechanic for a second opinion. It's still doing the same thing, and if I let it idle the engine dies after maybe 10 or 15 seconds, but if I gas it right away it doesn't Rev up fast but eventually does get up there and then it runs mostly ok, albeit noisier, now with a lower pitch noise accompanying the tap. The p0135 and p0035 are gone but now I still see the p0017 along with a p0170. Am I actually screwed or could it be something else? Maybe a bad alternator or battery or spark plug? Something that could have been fouled up by the engine flush?

It has happened three times now on cold startup my car makes this loud hissing sound then the car runs normally. Once a few months ago. Again a few weeks ago and this morning it was pretty cold maybe low 50's. I normally turn the key in the ignition to the "acc" position let it "ding" once then start the car. What could this loud hissing be that only happens on cold startup then the car runs like nothing happened? I called my local mechanic and he said he wouldn't know if he can't recreate the sound. Which you really can't because it happens once every blue moon but I wanna make sure I'm not ignoring a problem that could get worse.

I am having a new problem with a clunk when I brake my 2009 Sonata. It only happens the first 1-2 times I brake while going forward. In other words, I back my car down my driveway, no clunk. Then when I drive down my street, the first 1-2 times I brake it will start slowing and then suddenly I will feel the brakes grab and it feels like a clunk (although now real audible cluck, just the feeling). after the clunk my car continues to slow as normal. The rest of my ride I do not feel it. After I get out of work, it does the same thing as I am headed home.
I have never felt this before, and find it strange that it only happens after the car has been sitting a while and goes away after 1-2 brakings.

2009 Sonata; about 82K miles. Drive belt was replaced in July, about 6K miles ago, by Trusted Independent Mechanic in El Paso. Now, Trusted Independent Mechanic in DC area replaced it again because one of the belt's ribs was falling apart. Attached photographs show a portion of the damage (which is only on that one ridge).
Did that belt need to be replaced?What could have caused he damage? (Mechanic says pulleys look ok; maybe defective belt.)

Every time I slightly touch my brakes while in reverse, they screech loud enough to wake a whole neighborhood. Did I purchase wrong set of pads or is this common, ive asked around and no one can figure it out. It only happens while I press them in reverse...

2009 Hyundai Sonata GLS 4cyl 135k miles...
Everything has been going fine. On Thursday I stopped at a gas station. Came out and the car won't start. Had it towed back to the house.
It cranks, but won't turn over.
Fuel pump kicks on.
Spark plugs were worn, so changed them, can't hurt.
They spark, although it looks like it may be weak.
After changing the spark plugs and trying to start it, pulled them and you can smell fuel, so it is getting into the engine.
Checked the connections of the wire harness (all I believe)
Anything specific to this model that would suddenly not run. I drove it 3 times that day, no problems starting, running, driving, anything. So I'm kind of stumped on the sudden development.
The check engine light had been on, but I did disconnect the battery when I was looking at something else before I checked the codes. So it isn't throwing any now.

Last night, on my way home, I suffered a catastrophic transmission failure in my 1991 2.3L 5 speed. Stepped on the clutch on an exit ramp from the freeway and was rewarded by a LOUD screech/grind, a stopped vehicle, and a transmission "locked" in 5th gear. The local HERO service pushed me out of traffic and I got towed home. Looks like a transmission transplant is in my immediate future. So - the question is, what year manual transmissions match up to a 1991 2.3L 4 cylinder, standard cab, 2WD? I need to start searching salvage yards.

I feel my 2009 Sonata with 25k miles has a fast startup idle.
It goes upto 2200 RPMs. It runs fine otherwise.
I will keep an eye on it to get more RPMs and timing.
