So I installed my intake....again this weekend and have been monitoring it to make sure it doesn't pop off again. When you first start up, there is a very loud growl coming from the intake that lasts about 20 seconds. I also noticed that the breather filter kicks in during this time as well. Is this normal? I would yes but want to understand exactly why...
View 12 RepliesMy Honda has 61000 miles on it, it's an automatic . Just had oil change done at 59000, told was good for 5000 mil. The last few days I noticed a trrrr (kind of like a playing card in bike spokes but louder) noise coming from the front of the car, it lasts for a few seconds then stops. It happens mostly when it is in drive but not moving. Stops if I put in any other gear, doesn't happen while I have foot on gas. I did hear it very faintly today while coasting up to a red light otherwise it's always happened while in drive with foot on break. First time it happened was a few seconds after I stopped at a red light. Second time it happened was after the car was parked for an hour. When I got back in and threw it in drive it did it.
View 4 RepliesTwo months ago I bought a used 2006 Sonata v6 with 54,000 miles. After a few hundred miles I began to hear a rattle on cold start that lasts approx 5 secs. I did my research and saw the TSB concerning the timing chain tensioners. The TSB instructs the dealer to turn the engine off after reaching operating temp then restart after 10 minutes. If there was no noise after the ten minute start then the car is operating normally. My car does not rattle after the 10 minute start up. I just can't see this as a normal characteristic. What could be causing this noise?
View 1 Replies2006 Sonata LX. It's only on a cold start up and lasts for about 30-45 seconds tops..and then it goes away. Car has 74k on it. Treated well. Only use synthetic oil and no check engine lights. Last oil change I put 5w 30 in it. I know it says to use 5w 20. Could this be the problem?
View 17 RepliesFrom time to time I get this high vibration on start-up of the car. It almost seems like more of the engine noise and vibration is coming through to the cabin. It only lasts about 5 seconds from initial start up and the rpm does not change and stays constant. This only happens maybe once every other week or once a month. What or why this could be happening?
View 6 RepliesI have a 2013 elantra with about 26,000 miles on it. I usually don't use it on weekends and on Monday's it makes a noise that lasts about 3 seconds. I believe the noise comes from a pulley that is not turning.
When this first happened, pulley had a couple of lines where paint peeled off and now the pulley has almost no black paint left. Took the car to dealer, explained how the noise only happens after not using the car for a couple of days, and they have not been able to repeat the problem, they indicate that they can't replace the pulley for this reason and that the wear on the pulley is normal.
What is causing the issue?
Every once in a while, I hear a sound coming from under my car, possibly the passenger side, that sounds like I am pulling a tin can around. It only lasts about 3 seconds. Sometimes I'll hear it when sitting at a red light, or accelerating from a complete stop. Then the sound disappears. This doesn't happen all the time, but I do feel like I'm hearing it more often as time is going on.
I did a little research online, and some say it could be a rock under my heat panel, but that seems too easy. I don't have any issues with shifting gears or accelerating.
2000 GMC JIMMY 4x4
First of my truck is an 03, xlt 4.6 5-speed with 82,000 miles. Almost always when i come to a stop i can hear a faint humming that is coming from the engine compartment. There is no pattern or set way that this humming happens, it just comes and goes when at idle. As soon as you put load on the motor it will go away. I got under the hood today and fired it up, nothing, gave it just a little throttle and sure enough here is this odd humming. It is coming from in the air intake. Also while i was under there i noticed that the cable that is right next to the throttle cable is very loose, i am not sure what this cable goes to or if this could be part of my problem
View 14 RepliesThe engine starts with knocking, rattling, and vibration that lasts for about 5 seconds. It seems to be an intermittent, rare event. With nearly 250,000 Prius in the North American market and the onset of cooler weather, it is time to see how frequently this occurs.
View 19 RepliesThis has happened twice so far, both with around 1/2 tank. After driving for ~25 minutes to work, I will go to shut the car off, and after pushing the key in and pulling it out, there is a mechanical noise from the rear of the car that lasts for about 2 full seconds. Is this the sound of the fuel pump on its way out? Or just an electrical gremlin (no! not in a VW!)?
View 7 RepliesI have a 2003 Subaru Forester with 240K miles on it. When I start the engine in the morning, there's a squealing noise under the hood that lasts for a few seconds. (Usually goes away as soon as I pop the hood and look at the engine.) I think it's one of three things: AC compressor, alternator, or power steering pump, but I haven't been able to isolate the noise to one of the three. I don't want to wind up replacing all three.
View 4 RepliesI just bought a used 2003 Pilot with 62,000 miles. I quickly noticed a that I hear a faint rumble sound that lasts about 2 seconds at speeds between 30 and 40. It sounds like I ran over a very short and shallow rumble strip. It can happen very quickly as I slowly accelerate. It only happens once, but not every time that I slowly accelerate. It also happen as I am coasting at these speeds. I took it back to the dealer, but they are puzzled. They thought I was crazy until I took them on a test drive and we eventually heard it. They tried adjusting the sway bar, but the sound continues.
View 8 RepliesI have a 2005 Honda CRV with 139,000 miles that recently developed a miss. It usually does it while holding steady at 50 mph but only lasts for a couple seconds. If it misses may do it once or twice and then nothing the rest of the day. Had the dealership put it on the computer for a reading and they said it's showing no misfires and is running properly. Plugs have been changed other maintenance performed and have had absolutely no issues until now.
View 3 RepliesThis winter, my little green Echo sprang a noise. I noticed that when I turned on the heater plus fan that it would often (but not always) make a ch, ch, ch, ch, ch, ch sound that would last maybe 3 seconds then fade away, only to be reawakened when I started accelerating after a traffic light. For a while this winter it seemed to happen multiple times in a jaunt about town. (I would usually get a bit nervous, promise myself to have it looked at by my Echo car-diologist, and then turn off the fan for a while.) Just when I was about to take it in, it stopped happening, even with the heat/fan on full. And now it has started happening again. I know peanuts about cars, but my intuition says it's some kind of belt in the fan that's slipping. The car has about 75,000 miles on it....
View 2 RepliesI used the a/c for the first time this year on my 2013 F250 and heard some noises I don't remember hearing before. When the a/c(or defrost) is on every 12 sec or so I hear a hissing sound that lasts for a couple of seconds then goes away. Is this the compressor cycling and if so is it normal to hear it inside the cab?
I know it has to do with the a/c because if I shut it off as the hissing sound is being made the sound will instantly stop. Other than the noise the a/c works fine and blows cold air. Also, if it matters I have the standard control panel, not climate control.
Couple days ago I took out the factory air box and cut the bottom out. I also cleaned my K&N filter at the same time. I cut the whole bottom edge to edge up to about 2" from the flapper on the motor side of the box. Re-installed and everything is tight. I drove the car and noticed a LOUD or what I consider loud noise from about 3,000rpm to redline. I am thinking it could be just the additional air being sucked from the air box. However its much louder then I would expect from a CAI. Does a CAI make a loud difference? I noticed a increase in performance so I know its working. Also, it could be described a a light, smooth sounding exhaust leak. But I am susceptible since this problem was not their prior to the intake mod.
View 6 RepliesHaven't had my Azera Limited 3.8L very long. Got it because I wanted a comfortable cruiser.
Because today, I was on a fairly short acceleration lane trying to merge onto a busy Interstate. As I was getting ready to slip into the only large opening between 2 vehicles, the rear one, a black Escalade, started to speed up. With the end of the short on-ramp coming up fast, I stomped on the throttle.
Didn't expect to hear the engine/exhaust growl so loud when the full 260 hp kicked in. Surprised me and my passengers. I know it's fuel injected, but the sound reminded me of the huge secondaries opening on a Holley four barrel carburetor. Wouldn't be surprised if the Escalade driver also heard it as my Azera jumped ahead an easily merged.
The wife has a 2007 Buick Rendezvous that makes loud growl after starting. Doesn't happen immediately, sometimes it doesn't happen at all. I have not been lucky enough to have it make the noise when I have the hood up. But from inside the car it sounds like it's coming from the driver side close to the firewall. I know "belt noise" when I here belt noise. This IS NOT belt noise.
View 4 RepliesI purchased a 2011 Sonata about 6 weeks ago. I like almost everything about it, but the engine is very noisy. I'm not talking about a loud growl when you accelerate, but it's almost sounds like there are 2 frequencies sounding at once. It's higher pitched and at times sounds like pinging or clattering. It's very hard to explain. Unfortunately, sometimes it's worse than others and when I've taken it to the dealer, it's not at it's worst. The dealer I purchased it from told me that it was normal, even though I drove another 2011 on their lot that did not have the sound. Another dealer told me that it was a loud fuel pump because of the high pressure of the injectors and that Hyundai is aware and is working on a new "cover" that should muffle the sound. When I contacted Hyundai directly, they did not know of any new "cover" being developed . Assuming I've described it well enough to know... The only thing I know to do is wait for it to get consistently worse, and take it in again.
View 35 RepliesFirst bit of cold weather and I'm getting thirty seconds of loud clicking (or clacking) coming from the immediate vicinity of the blower motor on start up and shut down. Doesn't matter whether my climate control is on or off, it still makes the noise. I'm assuming it's stripped out teeth on one of the blend door actuator gears and I'll probably just end up replacing it. My problem: Where exactly is the offending actuator? I've removed the glove box and noted one located on the left side. I unplugged this but am still getting the ratcheting sound so it obviously isn't the culprit. I had this happen a few years back (same time of year) and out of ignorance and frustration solved it with a well aimed kick but the way it's acting this time I don't think I've got a big enough boot.
View 4 RepliesI have a small clicking sound coming from my intake manifold. I recently installed a boost gauge and it did it once after that... I shut the car off and I didn't hear again until 1000 miles later and its back, why it would be clicking like this but its annoying
