Started up my rig yesterday and heard a very strange screechy sound that got louder when I rev'ed the engine. After a minute or two it went away. Same sound this morning and whenever the truck sits for more than an hour. Sounds like a turbo problem and is coming from that area under the hood..?
View 11 RepliesIn my 2007 Sonata, I hit a poorly placed high manhole cover in a dip in the road, in the dark, going 30MPH, whacked it good before I could adjust...
I then pulled the car over, it seemed to go dead, then the car did crank back up, the engine sounded much louder, like a loud rev/hum, not quiet like usual.
I next drove a mile to a c-store, transmission seemed OK, no leaks, did see a check engine light briefly, but it disappeared. Car cranked OK, headed home, same sound right at cranking and at moderate speed.
Finally, I jacked the car up on the front left, from research appears that the plastic engine shields got smacked good along the front and near the right tire and bent back quite a bit on the left side. There seems to be no other structural damage that my untrained eye could see, just one indention you'll see in a couple of the photos that I think is part of the car design at that spot.
Again, no leaks, no smoke, no caution lights of any kind now.
Photos are attached...
My Hyundai's engine now sounds like a Mustang! Hoping it's just the engine noise from these plastic covers now being bent/destroyed in some spots, exposing the engine and the typical noise you'd hear without them...
I cant recall if these sounds were there when i first bought the car, probably because i have the radio on most times. I think the buzzing sounds were present in the last month at least.
After i start up my car and even after idling for a while, i hear a buzzing sound coming from the engine. It gets louder when I accelerate. When I let go of the gas, the buzzing sound lags for a few seconds and then quiets down a little bit, but still can hear it in the background.
I lifted the hood up to listen more closely. I am not totally sure, but i think i can also hear a faint hissing sound ( sounds like leaking air?). I cant pinpoint where it is, but its around the engine.
I also notice that when I am idle, the MPG number in the dashboard is dropping fairly quickly. Like 0.1 mpg every 20 seconds. This is new and started today. I last drove it 4 days ago and didn't notice it happening then and i watch the mpg very closely every time i drive. Could there possibly be some gas leak?
over the past two weeks my 2011 GTI seems to have gotten a bit louder and has a low frequency rumble when on the lower end of the gears (DSG). Any thoughts on this? From the exterior the car doesnt seem louder to me at all. I have a stage 1 APR and everything else stock
Maybe I am going nuts but it is bugging me!
Recently my brother in laws truck started making a buzzing sound while running and a much louder sound after it shuts off. Trying to track down the sound. Listen to the whole video because the end is where it gets loud.

I have an 02 limited and I have noticed that the frontend is getting louder I kinda think a baring is going out. What else it cloud be?
View 3 RepliesMy daughter bought this truck about 6 months ago. This morning a driver cut her off, then hit his breaks. She had to make a panic stop. When she went to take off again, 1st and 2nd was no problem. When she shifted into 3rd, the engine just revved.
She tried to shift back into 2nd, but it wouldn't go into 2nd. She pulled over and now it won't go into any gear. The shifter lever won't even go over far enough to go into 4th, 5th, or reverse. I doubt the panic stop had anything to with it, but thought I'd throw it out there, just because.
Okay here's the truck: 1997 F150, 4x4, base model, short bed, 4.6L, 5 speed manual, manual transfer case, 190k miles. Truck has been beaten and abused badly, but is basically mechanically sound.
Here's what I've done so far. Checked the fluid, it was fine. Pulled the top cover and shifter lever out. I don't have a clue what I was looking for in there, but I hoped to see something obvious. I didn't.
After putting my front end back together except new springs, new shocks, and new track bar, just to give everyone a little history of what I've done to it. I've had it for 8 months and maybe put 1000 miles if that because of working out of town a lot and the front end torn apart. I've noticed a louder roar coming from the rear end when taking my foot off the accelerator without pressing the brake. It feels like the tow button is engaged, but isnt. I have no issues with handling besides knowing it still needs alignment. I'm taking it to the dealership tomorrow for a 4 wheel alignment. It sounds and feels like I'm riding on mud terrain tires.
View 14 RepliesIt started after a blue spring upgrade. my turbo would not spool until we revved the engine hard then it kicked in and it's kinda worked since then.. it feels like the truck is struggling on acceleration and the boost builds fast up to 30lbs, the EBP seems to be stuck at 21.48psi until your in 3rd then it jumps and I have power again, also the turbo dumps (farts) if I let off even a little until the EBP jumps then no issues. I replaced the sensor and it's stuck at 21.48 all the time.
Now, I unplug it and it jumps between 26 and 28psi, plug in the old sensor while it's out laying on the motor (not installed) and right back to 21.48. I don't know where to go with this and it's my only truck so I need it running. also it was blowing the intercooler boot off at the turbo during a normal acceleration and the turbo spool has a howl to it when EBP is stuck...
I have a 98 ford explorer just changed the alternator and now its running rough also it sounds louder than normal from the muffler. I am clueless, what the problem can be?
View 7 RepliesJust wanted a little louder sound. Was thinking about swapping the muffler for a flowmaster?
View 13 RepliesDrove about 10 mins and parked. Came back 5 mins later and wouldn't start. Starter click can be heard when trying to crank but doesn't turn engine. Checked fuse (#113) and starter relay - both are good. AAA came out and tried to jump but no success. Flat bed towed back to my house last night.
This morning, woke up bright and early to pick up brand new Napa Premium starter. Replaced it thinking that was it. No dice- same thing, 1-click, no turning of engine.
Batteries & terminals both good & clean. Hooked up 2 additional fully charged deep cell marine batteries via jumper cables and no difference. Voltage @ starter terminal = 12.4V.
When cranking, voltage drops all the way down to 1-2V if holding the key in the crank position (1 click and then nothing). Returns back up to ~12V when released.
Jumped pos terminal to starter solenoid, got clicking but doesn't turn engine.Is my tranny or engine frozen...?!
2008 Passat with TSI and tiptronic transmission. The wife has two instances were the engine speeds up on it's own. She swapped vehicles, so I wasn't able to get into all the details, but it sounds like the engine rev'ed up to 5,000 rpm, but the car didn't speed up. Transmission dropping out of gear or downshifting?
View 2 RepliesI have a 2004 Ford f-250 super duty 6.0 turbo diesel. I noticed yesterday that it was making a jet sound when i pressed the pedal and got louder as i increased the speed. When you let go of the pedal it goes away. I have asked around and some say it could be the turbo...the diesel mechanic THINKS it could be the fan clutch. The truck doesn't overheat and if i punch it i don't think i sense any loss of performance. All I know is that it makes this sound like a plane taking off.
View 14 RepliesI recently bought a 2006 prius used with 100,000 miles and have been hearing a very disconcerning sound coming from underneath the car. It is a screechy noise that is always there, but especially when i accelerate or break going up a hill. I have had it checked out by both a dealership and an independent mechanic neither party has info what it could be, even after hours of troubleshooting, as well as showing then a video in which you can hear this awful sound.
View 4 RepliesI was driving down a long steep hill on the highway going about 65. I put it into engine braking, B, because I didn't want to just ride the brake the whole way down. The engine was revving pretty loud and with no RPM guide, I had no clue if it was OK, so I ended up going back into D and just rode the brakes all the way downhill.
View 19 RepliesB2200 mazda: I've recently got a screechy noise only when in gear but gas pedal NOT depressed. Could this be an indication of a bad U joint noise? Or? The noise seems to be coming from the rear chassis of car. Noise seems worse if going in reverse. Possibly coincidentally I started noticing the noise after a shock absorber worked its way loose, causing lots of racket. (The mechanic who'd installed it has since tightened it.) Would all that rumbling from the loose shock have caused something to break or work loose? Or is it just age of vehicle (22 yrs) By the way, the noise is very similar to a wire scratching metal. I also have had the classic thunk noise of a u joint, for a longer period of time-- never looked into though.
View 1 RepliesMy girlfriend said her 2008 GX has been acting weird recently. When in park, if the engine is revved, the RPM's don't drop after letting off the gas. The RPMs do eventually drop but it takes a few seconds and it doesn't do it smoothly. The vehicle also maintains a pretty constant speed while driving and letting off the gas with very little deceleration. Is this normal for this vehicle or could something be wrong with it?
View 5 RepliesMy fiance' can't drive stick so, I got her a 2005 jetta gli with tiptronic.. It's been fine up until today.. She was driving along, than it was like the engine revved up a little bit with out going faster, and now its making a slight whining sound, which also follows blipping the throttle in ANY gear, including park.. Its 1.8t, with about 135,000 on it.
View 13 Repliesin order to make my car sound louder, which part can be removed without triggering the check engine light? Central catalytic converter? how many are there on the v8 phaeton?
