Pontiac - Grandprix :: 2007 - High Pitched Grinding Noise And Smoking


Jul 16, 2011

I've got a 2007 pontiac grand prix that I picked up off a guy for $900 and so far it's been a head ache. So far, I've had to replace the power steering pump, pump lining, there's a hole in the radiator, and now a mystery problem that me and my lack of car knowledge can't diagnose.

Smoke/steam (smells burned) is coming from behind the engine and when the wheels are turned, it sounds like a high pitched grinding noise. I checked the oil, its fine. I filled the radiator with water as a temporary fix until I can afford to get the radiator fixed or repaired. Air conditioning only works on max setting. Before the problem occurred, I was pouring water into the extra reservoir when my friend started the car. Maybe the radiator sucked up some air while I was filling the reservoir.

Acceleration - Pontiac - Grandprix :: Grinding / Rumble / Vibration Coming From Front Along With Power Loss

Car: 2004 Pontiac Grand Prix GTPEngine: 3.8L SuperchargedMileage: 94,300 miles

Issue : Usually after driving the car for a long period of time (approx 20 miles or more), Ill begin to hear a grinding coming from the front of the car. The grinding/ groaning can be felt in the gas pedal as well. Depending how hard I hit the gas the frequency increases. I am not sure if this is associated with the grinding, but i noticed that when I turn sharply and go easy on the gas and progressively add pressure the car will cut out until i cut straighten the wheel. Then all the power I requested is applied all at once.

What the locals think :

CV Shafts - Sears told me the first time i went to get them checked that my CV shaft boot was a little loose, suggested changing it. Then I went back two weeks later and they denied saying that and said my cv shafts were fine. (talk about confusing)

Wheel Bearings - Someone I know said my wheel bearing could be slipping or my traction control could be on its way out, so i replaced both front bearings.

Tune up - Someone suggested it could be mis-firing, with it coming up on 100,000 miles, i did a tune up. (plugs, wires, coil packs)

Transmission - Someone said the transmission could be going bad. So i did a flush and inspected the fluid, no shavings or any sign of extreme wear. (car shifts great too.)

Clogged Catalytic converter - the cat was clogged, two new 02 sensors and a new cat didn't even solve the issue I am describing, but it does have more power now.

Throttle Body - Someone said it could be a dirty throttle body....so i had that cleaned also.

And finally, some electric temperature sensor - someone said it wasn't getting the right fuel mixture, so i replaced the sensor to remedy that.

Fuel pressure was also tested to ensure the fuel pump was doing its job, everything checked out great

Ford F-150 (2009-2014) :: 2011 - Grinding Noise / High Pitched Squeal On Front End?

This evening, my F150 with 2,600 miles developed a high pitched squeal, much like you might experience on an older vehicle with failing front brakes. Yes, that same squeal/grind the brakes make...metal on metal. It came in instantly while at highway speeds. It was VERY loud. The pitch didn't really change with speed...it was pretty consistant going slow or fast. There was no vibration, chatter or growl as I would expect with a failing bearing.

It was definately in the driveline/brakes. I was 10 miles away from a friends house, so I turned around and took it back to his place. Shortly after turning around, it quieted, only sounding when I would turn ( like a wheel bearing would when being side loaded ). I looked at the brake disks, thinking something was grinding on one of them. The outsides of the disks looked fine. Due to the shields on the inside, I couldn't see.

Later in the evening, I had to drive it back home, about 50 miles. Again, it was quiet unless turning fairly hard. By the time I got home, the squeal had turned into an intermitant growl/thump, as if a warped rotor was banging on the caliper. The noise was 1 to 1 with the rotation of the driveline. But still no vibration. Brakes work perfectly and the noise doesn't change with brake use. Backing up and turning hard results in a variety of sounds, including squeaks.

The hubs and CV joints felt cool. The brake disks were not hot as if they were dragging.

It is 4x4 / 3.7l

Camry :: 2007 - High Pitched Whirling Noise When Turned The Car

I have a 2007 Camry with 90k miles. All of a sudden today when I turned my car on I noticed a high pitched whirling noise, similar to a tornado siren that gets louder as I accelerated in my parking garage. Even when I turned the car off and on and it sat in park I still noticed it and it got louder as I press on the accelerator. I haven't driven over 20 mph since I noticed this so I'm not sure if it still does it at fast speeds.

Santa Fe (CM - 2007-12) :: 2008 - High Pitched Hum Noise When Accelerating

I have a 2008 Santa Fe LTD, and just recently started experiencing a strange noise when I am accelerating, and I cannot pinpoint it. Here is some info on the noise.

-2008 Santa Fe LTD AWD, about 25,000 miles
-Sounds like a little higher pitched hum, not very loud
-Seems to be coming from somewhere near the passenger side backseat area (first found out about it when someone was sitting there and asked what the noise was)
-Cannot tell whether it is coming from the interior or exterior of the car, but I think exterior, but it is definitely somewhere along the passenger side, from the back half of the car.
-Noise occurs when accelerating from a stopped position, only when accelerating, never when braking or idle.
-Noise occurs only when car is in gear (hitting the gas pedal in park does not cause the noise to happen)
-Noise doesn't occur at high speeds or when accelerating at high speeds
-Noise only really occurs for a 2-3 seconds while accelerating, then seems to go away as I continue to drive.
-Noise doesn't seem to always happen, but very frequently.

Pontiac - Grandprix :: 2007 - Engine Starts To Run Really Rough And Tach Climbing Up

The car runs fine for several miles/minutes, suddenly the tach starts to climb, up a jump, then up again. This is when the engine starts to run really rough and I pull off the road, let the car cool down and make it the rest of the way to work (about 15 miles).

Here is what I have done: Radiator flush and fill; Oil and filter change; Cleaned EGR and replaced gasket; put in new spark plugs; changed the transmission filter and oil; replaced the O2 upstream and downstream sensors; replaced the thermostat 195 to 180; replace the coolant temp sensor.

The check engine light does not come on (except on start-up check sequence), so it is working. Their are no trouble codes (other than when I removed the downstream O2 sensor to check if I would get errors). The cat converter doesn't glow at night, and doesn't rattle when tapped. The resonator in the exhaust does make a rattling sound, but I don't see why that would be the problem.

I am at my wits end. Any clue what I should try next? The water pump isn't leaking.

Lexus LS 2007+ :: 2014 LWB - High Pitched Engine Noise On 1st Start

I purchased a 2014 LWB six weeks ago. The vehicle runs great. For the last three weeks, I hear an unusual high-pitched sound when starting the engine for the first time that day (temperature between 40-60F). See videos below. Ride height is set to normal, so I don't think it is the air compressor. You may notice that the whine goes away when the idle rpm falls from 1500 on the first start.

First start (8PM), driver window open, high-pitched motor whine [URL] .....

Second start (8:05), window open, normal engine noise [URL] .....

Third start (8:10), window closed, normal noise [URL] ....

Pontiac - Grandprix :: 2002 - Clunking Noise Coming From The Front End

I just got a new car three weeks ago and I'm trying to sell my 2002 Pontiac Grand Prix GT myself. Since buying this new car, I haven't driven the Pontiac for 3 weeks. I started it tonight and it started just fine but when I started driving, I heard a clunking noise coming from the front end. I checked the wheels and didn't see anything (though I didn't check too thoroughly). It's definitely the front end. The car has about 158,000 miles on it and before I stopped driving it, it had no issues and did not have this clunking sound. I tried leaving the car running for 5 minutes at a time and then turning it off and then on again thinking it might be that I've just left it sit there but that didn't work.

Pontiac - Grandprix :: EGR Clicks On And Off Every Other Second

Engine starts then runs for a period of time until it warms up, then fans come on and then EGR clicks on and off every other second , then it eventually quits. Replaced the coolant temp sensor. And it never sets a code. Have checked wiring for shorts and nothing. Is it a ECM going bad?? When trying to drive it , it will only go about a half a block , then quits , Then will start up again.???

Lexus LS 2007+ :: High Pitched Whine With New Rotors On 2008 LWB

Just had 4 new rotors put on my '08 LWB after 70k miles. A few days later, I noticed a very high pitched whine that occurs occasionally at speed. When I brake, it stops, and it restarts a few minutes later. It almost sounds like what you detect during a hearing test, only louder. And before you ask, passengers can hear it too.

Lexus LS 2007+ :: High Pitched Electronic Whine On AM Radio Station

I get a very annoying high pitched electronic whine on an AM radio station that I like. It occurs all the time. Its like a grounding problem. It is so bad I can't listen to the station in my 2009 LS. Only one station, AM 810, has the issue. I don't have ML. Just a regular radio. No other radio issues.

Santa Fe (CM - 2007-12) :: High Pitched Humming Or Whirling From Dashboard While Decelerating

I am slowly coming up on my 3 year anniversary with my Santa Fe 2007 3.3 AWD transmission , and after 50,000 trouble free miles I've encountered a problem.

It started this summer when I was towing my trailer on about a 300 mile journey. It sounded like a high pitched humming or whirling from the dashboard, while decelerating. It would stop at around 15 MPH. You cannot hear it while cruising. After days of head scratching I determined that the noise is coming from the transmission. It comes from the output side, as it shifts through all the gears smoothly, however it makes the sound with the engine off while coasting with the transmission in neutral too.

I noticed the transmission fluid was slightly burnt. As I am student, the problem was solved by turning up the radio, and as the car shifts great no thought was given.

During Christmas break I drove the car out to the west coast and about 400 miles into the journey the whining really got loud and frankly freaked me out. The car now sounds like little aircraft jet engines whinding down when you decelerate. OK its not as loud but when you're 400 miles into a 1600 mile trip you tend to get panicky about such things.

The car made it back fine. It still shifts great except for the whiney turbine noises that disappear below 15mph. I've got transmission fluid so I will start today by doing a couple drain and fills, but I suspect that since I've been a bit too lackadaisical about the problem that will not be sufficient.

Pontiac - Grandprix :: 2002 - Air Conditioner Putting Out Hot Air

Hottest day ever on Planet Earth and my air conditioner in my Pontiac decides to throw hot air in my face! Luckily, for my female companion, she gets ice cold air. This 2002 Grand Prix 40th Anniversary edition has 236,000 miles, I never once had a problem with the air conditioner in the past (have thought about contacting GM asking what they did right in this car)This model has dual climate control. I noticed that in turning the selector knob on the dash climate control panel, there is hot air in the vent, bi-level, heater and defrost, but cold air comes out on the passenger side. The interior temperature functions are all similar on the '97 through '03 models of Grand Prix, just wondered if this is something I can fix, or do I need to visit a Pontiac dealer to have it diagnosed (and spend a lot of money)

Pontiac - Grandprix :: Code P0741 - TCC Stuck Off

Code is for tcc stuck on. Code p0741 is tcc stuck off. So, it's a sticky solenoid. Which means it may start out sticking occasionally and progress to sticking more often and finally staying on/off permanently? If u get the code/symptoms 1 time, does it usually mean it will happen again, soon?

Pontiac - Grandprix :: Overheating And Antifreeze Smell

We were driving home yesterday and all of the sudden the car started to over heat and we could smell antifreeze. We turned the ac off and put more water in it. Today we just had to make a short trip somewhere (we were planning on having it looked at first thing Monday morning). The temperature gauge never showed it overheating but as we pulled into our driveway we heard a knocking sound and it just shut off. Iit may just be a leak and it caused the car to over heat??
