Buick - Lesabre :: 2001 Loud Roaring Sound At Morning Startup
Jun 25, 2014
When starting my car first thing in the morning, for the first few minutes there is a loud roaring seems like. The sound subsides and the car sounds normally after a little bit. The next issue is when I start the car after it is already warm. It starts very strange...It is a little hard to describe. As soon as you hit the starter it just turns over instantly, seems almost prematurely. And when you go to shut the car off, it just seems like it makes a loud noise and the motor abruptly shuts off. I am not too educated with vehicles, and I am just looking for some input. I just purchased this car a week ago with 82,200 miles on it I have never driven a Buick before so these things may be normal.

As I begin to accelerate a humming sound from the front of the car begins. The noise becomes more pronounced the faster I go. No additional noise is made when I brake or turn, nor does it appear to be any noise when I went in reverse. I made a 180 mile trip on Sunday with no problems, although I did travel at closer to 55mph than 65. The car has 170,000 miles on it and has had most of its scheduled maintenance performed.

My 2001 Buick Lesabre has always shown to run exactly normal on the temperature dash unit until recently. I checked my coolant level and it was a bit low, so I added. After I filled the radiator I have noticed a coolant leak spot on my driveway, after I drive it now. I have removed the gravel shield and have tried to pin point exactly where the leak is coming from, but cannot. Now, each time I park, after driving it, I put a clean piece of cardboard under it to try to see exactly what area the leak is coming from. Last night I put the car on ramps and crawled under to discover that the leak is located just above the oil filter and is actually dripping from the oil filter, but I still cannot see the exact location of the leak.Actually the leak does not appear until about an hour after I park the car, so it sounds like something is contracting after the engine has cooled off, but what? The leak has seemed to be getting worse each time I drive the car. How can I determine exactly where the leak is coming from without just changing a bunch of parts.

I just bought a 2001 Buick Lesabre and it was driving fine until this morning when it misfired on the highway. I was going about 40 mph and I felt a little jerk in my engine and my CEL started to flash. I pulled it over and got it towed to my house and my code reader says a p0300...which is a random misfire code. So I figured i just need a tune up so I went and bought new plugs and wires and replaced the old ones. And to my surprise...still a noisy shakey rough erratic start and idle. Before this there were no problems the car shifted properly to all gears and picked up and accelerated like a champ there were no obvious issues. Now I cant get it out of my driveway. I was wondering if any other problems could cause this misfire, and how to eliminate problems without buying parts?

I have a 2001 Buick LeSabre (Limited), with 101,000 miles. It runs great and a very reliable car except:
After going for some driving in town during a warm day (60 F or above) doing business, the engine gets warm but within normal temperature range, and after making a stop to get groceries for eample, I have to be very careful when starting the car again. If I let the starter go for more than a quarter tourn (crank), the engine gets week and acts like it is flooded with gas, just like when we had carburators in old car and it dies after a few shakings.
So I have to wait for 15 minutes at least before I restart the engine but doing so I have to be really careful again not to let the starter crank for more than a quarter turn. However, this problem does not happen during cold weather days (say below 40 degrees F). What is going on with my car?

My 2001 Buick Lesabre 3.8 loses power at highway speeds, sets a PO101 code (MAF sensor). I have replaced the MAF sensor 3 times, as well as the coolant temperature sensor, the crank position sensor, the throttle position sensor, the MAP sensor, the intake manifold gaskets (upper and lower) , the pcv valve, the egr valve, the Idle air control sensor. After cruising at highway speed for about 3 miles the car still loses power for about 20 seconds then gradually regains power only to repeat the fault again 3 or 4 miles down the road.
Otherwise the car has plenty of power quickly achieving 100+ mph going though the gears smoothly and normally. I have inspected the intake plenum and vacuum hoses for leaks and have found none, all in very good condition. The car ha 122,000 miles on it and has been well cared for, very clean under the hood with no leaks. I did reduce the egr chimney size to 3/8" while replacing the intake gaskets and that reduced the symptoms somewhat, i.e., the car only loses about 15 mph instead of dropping to about 25 mph before recovering.

My G1 prius (2001) started making a grinding noise when I start it up in the morning. There are no warning lights (yet) and it drives fine, but that noise can't be good -- something will fail shortly. I've searched the internet quite thoroughly and there was one similar problem reported, which ended up being linked to the ABS pump. The noise seems to come from the inverter, or somewhere under the inverter. I took a video of it and posted it here.

I have a 2001 Toyota Camry with only 56,000 miles on it and I have noticed that the engine has been very sluggish on start-up first thing in the morning. This happens only when the weather gets cooler and is worst in winter. Warm weather, no problem. After I back out the driveway, I have to step on the accelerator 2-3 times before the car will go forward. The engine sounds like it's straining. After initial start-up, no problem. Now, lately I have begun seeing blue smoke coming from the exhaust . . . again only on initial start-up in the morning.

2001 Buick Regal with approx 250,000 miles. 3.8L V6. Non supercharged It's my son's car. Used to be mine, I bought it with 19,000 on the clock.
The battery succumbed to the cold weather last Monday. On Tuesday, I put a new battery in, which itself now works fine. However, since then, the car refused to idle decently. It'll idle right after startup, but once you put it in gear, it'll die. When you start it, it seems to idle normally, you can let it warm up a bit and it'll settle down to about 900 rpm. BUT! Once you put it in gear, it'll stumble and die.
This problem started after battery replacement, so I have to wonder if it's somehow related to that. It ran fine before the battery died. I checked everything over thoroughly, and visually everything looks OK. No loose wires or hoses, etc.;
Today is the first time I've had to work on it since the new battery, so I thought I'd get it out there. I'm getting ready to go put a scan tool on it and will report back with those results.

Lately my Sienna makes this noise whenever it is started. The noise lasts for 5-10 seconds. It builds up very loud towards the end and then stops abruptly. I made a recording of the sound and have attached it.

I have a 2002 Prius that is running fine except for a loud noise when I started it up---like the one the exha fan in my bathroom makes, but the car runs well and there are no lights or any other indicator that anything is wrong. I am taking it to a local mechanic today, since I don't trust my local dealer. My car has about 95, 000 miles on it.

I replaced my GF's water pump, timing belt, tensioner and roller on her 05 Elantra. WHen I started the car up I can hear a loud whine from the belt.
Everwhere I searched I read that it's too tight.
But in this video: [URL] ....
At around 9:11, when the guy starts the car it's the same exact whine? Is this normal or something with a brand new belt? Or did he tighten it too much? Or is it because her timing belt covers are missing the rubber grommets, and there is a HOLE in the side of one of them. So am i getting the full brunt force of the timing belt?

I own a 2001 Buick Century Limited that has 208k miles on it. A couple days ago I started the car up at a friends house and noticed that it had a loud rough idle and that the check engine light came on. When I drove the car home, the CEL would flash when I accelerated and I could smell something burning. When I released the gas pedal and coasted, the flashing CEL would return back to a solid state but I could still smell the burning. When I would accelerate, the CEL would start to flash again. Whenever I was stopped at a stop sign, the flashing CEL would again be solid and there would be a loud rough idle along with the same burning smell. Am I looking at an engine replacement or an easy fix? One problem or could it be multiple problems?

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 have recently noticed that my car will stall out when I get up to about 20 mph. My car starts fine, no check engine light on. I has a tendency to just die in the middle of the road at times too. I have changed the spark plugs, spark plug wires, and a new fuel filter. Do I need to change the mass air flow sensor? Or the crank position sensor? I have no problems starting the car either. Runs good when it runs.

Just recently starting hearing a loud roaring noise while driving my 07 Camry V6 XLE. It sounds like the gears are not shifting, like it is staying in low gear. Sometimes the sound will lessen if I'm driving over 15 mins. and some times it doesn't. RPM is around 2 or less, typically 1.5. Tried to check the transmission fluid but could find the stick. The car has about 142,000 miles. I hope the engine is not going.

I have about 200k on my forester. Friday when I was leaving work I cranked it up and it made a loud knocking sort of sound. I drove it home (about 15 miles) and on the way the sound lessened. It was louder when the car was idling but she made it home ok. Next day, started the car and it happened again. Not more than 50 feet up the road we stopped at a stop sign and it sounded like a semi was starting up around the corner. Much to my dismay it was not a semi but my own car. Engine shut off. We pushed it back to the house and tried to check it out the next day. This time, we started it, didn't go anywhere, and within 30 seconds it turned off. Same loud knocking sort of sound. The confusing part is that all of this happened within two days. There was no gentle sound leading up to it for a few weeks or even a few days. Knocked on Friday, shut off on Saturday. What could be going on?

I am experiencing a fan noise that precedes the ICE during morning startup. It sounds like a model airplane with a cheap, buzzy propeller. It is not the cabin blower and it comes from the front of the car. It goes for about 10sec and then the ICE fires up, drowning out the fan noise, which I presume fades out. And then I don't hear it again when the ICE shuts off. I also don't hear it at a stop light or subsequent restarts. Seemingly, it only does it after it has sat overnight.
It wasn't always like this. Nothing has changed in my routine. Build date Sep 09. 10000km.
