Gmc - Envoy :: 2008 - Loud Revving Noise While Driving And In Park
Jan 28, 2016
My GMC Envoy is making a loud reviving sound upon start up and while driving getting louder the faster I go. It also makes this noise while in park. I have Manuel transmission however it almost sounds like the car is in need of shifting to another gear... I'm hoping it's not an expensive problem!! There is no engine light coming on alerting me to a problem. It's a very loud revving almost whining sound.

I've recently purchased an 02 Envoy from an auction. There are a couple of issues. The main one started last night. While at the store I put the truck in park and turn off the ignition. The ignition will not go into the lock position. I messed with the key and go it to turn off. Then started the truck to leave and couldn't put the truck in gear. I messed with the shifter and was able to put into gear.
At that point the gear shifter would move from park to reverse without me pushing the break pedal. I drove home and could not turn the key all of the way off again. Moved gear selector from 1st to Park a few times and then was able to remove the key. I restarted the truck and could not move the gear selector again; however I was able to remove the key easily.
I am leaning towards replacing the "Neutral Safety Switch" on the tranny but with my symptoms, I've seen brake light switch, ignition, and solenoid at gear shift selection.
Back up lights do not work either. Since I purchased the truck, I've replaced,

-Ignition Coil

I bought a CPO 2010 Camry LE (2.5 4 cyl, 6 sp auto) a few months ago. The car had around 34K miles when I got it, and ever since then, it has had a high pitched whining noise when accelerating or revving the engine in park. It is noticeable from around 2500RPM up, and seems to be a little louder when the engine is cold.
I have left it at the dealer twice, and both times they have come back and said it is normal. I can't believe this, because I have owned many cars over the years, most of them being fairly dilapidated, yet most of them haven't had a noise like this. I think I have read a comment online somewhere that an issue like this was found due to a bad power steering pump .

My 2000 7.3 2wd is making a knocking sound while accelerating. It speeds up as I accel and when I let off the gas it gets louder. It slows down all the way to a stop when the truck slows to a stop. I can feel it in the floor board a bit as well.

I've noticed that when I've driven, park the car in the garage, turn off the engine, trans in park, a loud popping sound coming from the transmission (?) It sounds as if the car is clicking, popping into gear, although it's in Park. The garage is level and the car is not being moved in any kind of way. I sometimes sit in the car to finish a song or a phone call and I noticed this yesterday.

I have a 2003 GMC Envoy I6 4.2L. When driving above 50 after vehicle has warmed up it will drop rpm's by 300-500 and they go back up. This happens for several minutes at a time. It did it for over 20 minutes last night while driving home. I thoroughly cleaned the throttle body this morning (removed to clean) because in my researching for the solution it seemed that was the answer. Also left battery disconnected the entire time to allow computer to reset itself for clean TB. Took it for test drive and after about 10 minutes of driving it started doing the same thing. Took it to autozone to see if maybe they could pull a code even though there is no SEL on at the moment, but nothing came up. I am dreading if it's in drivetrain, i have only had the vehicle for about a week and a half. Bought it used from a private seller and it drove home fine the day i bought it and a couple days after, but now it's gotten worse than when it first started.

I have a 2008 Chevy Malibu LTZ and last week I noticed a revving noise like a fan or something whenever I accelerated from a stop and turned left. Continues throughout the turn and stops when going straight. Doesn't happen on a right turn. Also happens on a windy road when turning left more sharply than just a gradual turn.
Also just noticed this in stop and go traffic. When accelerating slightly and letting off there will be a short grinding/clicking noise that lasts 2-3 seconds or sometimes until I hit the accelerator again.

2008 Passat 2.0T auto, started occasionally shifting with a loud bang into and out of park, and from forward into reverse and reverse into forward. No MIL, pending transmission communications error code. Would accelerate very poorly up until about 30mph and then accelerate normally. Shutting the car off and then restarting would usually clear up the symptoms. Started happening about once a week over a 3 week period, and then started happening about about every other day. With it happening more often, had an opportunity to experiment a little, and by shifting into sport mode (which causes the MFD to display the gear that the transmission is in) noticed that the car was not shifting into 1st to 3rd gear, but starting off in 4th. With that and the rough shifts in and out of park, I thought that it was probably transmission related,
With a tranny being $$$$ and the battery being 4 years old, and relatively cheap to replace, I decided to play the long shot and see if a possibly weak battery was causing an electrical problem in the transmission. The battery checked out OK at a couple of places, but decided to give it a shot and replace it anyway.
Installed the new battery (Bosch from Pep Boys $109) and had every warning light on the dash go on with the first restart, along with a return of the harsh shift out of park problem. Shut the car off, turned it back on, drove five miles, all the warning lights went out, and no return of the transmission problem after 5+ months and 10K miles.
Just a heads up - if your battery is 4+ years old, and you are getting any odd problems that could in any way possibly be related to the electrical system - which includes just about every system on our cars - consider going for a new battery. Worked for me.

Getting a loud rattling noise from the front of car in Park or Neutral? As soon as I put the car in D/M. I have heard that the transmission is noisy in neutral, but just want to double check.

I noticed today when my Touareg is running but in park, each time I step on the brake I hear a loud clicking noise coming from the shifter. I assume the noise is the safety lock engaging and disengaging that allows you to put the car in gear while the brake pedal is pressed. I never noticed the noise before but usually I have the radio on. Is it normal to be able to hear this noise?

I've got my 2013 sonata and have noticed over the past couple weeks that after the car has sat for a while and I shift out of park that it makes a thunk/shifting sound that's coming from right below the car. I think it's coming from the gear shaft but I'm not a car expert so I can't be sure, it's more prevalent when I shift into reverse. What it could be? The car is still completely under warranty so I'm fine with making it the dealer's problem.

Car is a 2004 santafe 3.5l automatic. symptoms are phantom revving up to 3-4k in park without me doing anything, sometimes car is hard to start, idle is very erratic/doesn't want to stay running. other times it starts and drives perfectly. from what i can gather this is some sort of malfunction in the electronic throttle system, and from searching people say "inspect ETS system", but i'm not sure what this involves. i unplugged every sensor i can locate in relation to the throttle system, cleaned them with electronic spray cleaner and put some di-electric grease. reset the ecu through battery disconnect, and problem came right back. local shop pulled the codes and said it'll be about 1200 for a new throttle body, and that the dealer has to reset it say what.
is there anything i can do with this sans bringing it to the dealer? i'm not even sure it would make it that far, driving home from the local shop it was in limp mode and i could only drive about 30 mph, and barely made it up hills. probbaly take me three hours to drive to the nearest dealer lol.
i replaced the accelerator pedal sensor about a year ago, and it also threw a code for throttle position sensor about a year ago also.

Is it possible to cause damage to a vehicle (2003?? Chevy Trailblazer) with an on-the-fly 2WD to 4AWD system by switching to 4AWD when the vehicle is in park or otherwise not driving forward? This was done by someone and now the vehicle is making a loud noise.

2002 Elantra engine is revving up to 3000 rpms when in neutral or park. I changed the Throttle Position sensor and it went right back to revving up. Code read P0121. What might be causing this? Seems like I get one thing fixed and then another code shows up..

I have a 2007 Elantra with 138,000 miles. I never had any slipping or jerking or reverse issues in the past. I got into the car put it in reverse just fine then put it in drive and nothing happened, I put it in park and the car kept rolling like in neutral and started making a loud grinding noise. When I put the transmission in any other gear the noise stops but will not move and acts as if in neutral.

Here is a link to the audio [URL] .... It makes this noise, whether I'm at idle or running, granted it seems to be happen more when moving, its quite intermittent as it stops sometimes. I replaced the serpentine belt a month ago, so it can't be that. Its coming from the front of the engine. Sounds almost like the fan bearings or something below that is scraping. I've turned off the heater and it still does it, but the fan is spinning all the time, so I'm not sure what is going on.In the background you can hear cars going by on the overpass above, but I'm focused on the grinding noise. Car is not moving, its in park and makes the noise when moving also, with gas or at idle.

I have a 2003 GMC Envoy with 76000 miles on it. I heard a louder exhaust noise than normal when I start the truck in cold weather. I had it checked and was told that the exhaust system was OK but that the noise was because the motor mounts needed replacing. I have never heard of this before. Before I spend this money I wanted to see what your reply was to this question. Is it common for motor mounts to have to be replaced on this type vehicle with this mileage and age?

I just got a used 2015 with only 1000 miles on it. Everything is great except I notice when going up and over the mountain highway I take everyday to work the car revs kind of loud and feels like there's not a lot of power. I don't know if this is normal or not, but it doesn't sound right to me.

Is it just me or does the shape of the is-f make it really hard to enjoy driving with your windows down after 20mph? Strong wind in your face, loud buffeting in your ears. Opening all 4 windows better but it's still one of the worst vehicles to drive with the windows down I've ever driven...

I have about 2000 miles on a new V-8 and there seems to be a loud tingy noise if I really get on it say above 4500 revs either driving or in park. It seems to be coming from either the catalytic converter or exhaust area. It is a very metallic clanging noise that is very audible outside the vehicle under heavier throttle positions, almost like a metal plate hitting another piece of metal.

Just bought a new to me 2009 prius with 50k. Love the car thus far, and am learning more and more about the hybrid stuff.
One question i do have, that the dealer didnt explain well, was the planetary transmission. specifically the noises.
Its pretty quiet, but from a cold start, and into reverse, its the really odd noise. It sounds kind of like im backing a front plastic lower air damn off the curb. Like the hard, hollow plastic ka-klunk. it never does it from park to drive, or after a while of driving from park to reverse.
