Buick - Century :: 2003 - Hum And Slight Vibration At Speeds Over 20 Mph
Apr 25, 2012
I have a 2003 Buick Century in automatic with overdrive. During the past week I experienced a hum and slight vibration at speeds over 20 mph. (The faster I drive the higher the hum.) I checked the transmission fluid. It was brown and pink but did not smell burned. I have not changed the trans fluid in 2 years. I sent it to my transmission guy for an oil change. He said that the 1st gear clutch was having some problem and there was no 4th gear. He suggested another transmission...

I have a 2003 Buick Century 3.1L. The airbag light goes on randomly. I realize that it is supposed to go on momentarily after I start the engine. Sometimes the light will stay lit for one or more drives and sometimes it will stay off for one or more drives. I have checked the fuse; it is good. I have tried smacking the airbag on the steering and the dash...the light remains lit. I have seen a bundle of wires on the back side of the fuse box and am not sure whether I should try to trace the fuse wire back to both locations or what to do next. Is there some trick of the trade like a reset button and what do you think I should try next?

2003 Buick Century draining fully charged battery overnight. Have tried almost everything and cant figure it out. The high blower is not working either and I am wondering if a short in that can cause the battery to drain? Changed fuses, alternator, searched for shorts, an so on. Cannot find location of the blower.

I have a 2003 Buick century custom, 45,000 miles. I just got it 3 months ago, so don't have any maintenance records. Recently, the steering wheel has started to shake/shimmy while driving. It shakes left-right about 1/4-1/2 inch when I let go of it. The car also pulls to the right quite a bit. The steering wheel doesn't seem to shake at all at stops, only while in motion. My dad and I are going to look under the hood at whatever we can tomorrow, so where to start checking for issues!!! I am have been able to fix things before on my own and my dad has rigged his pickup to run partially on hydrogen from water, so gets 75 mpg city from an old 1990 beater that's falling apart physically, so we should be able to fix this if we can figure out what it is. So somewhere to start is what I'm looking for now.

I have 2003 Buick Century. I started having problems with the car after coming to a stop, accelerating - the car starts to go hesitates, then jerks a bit to go. This does not happen every time after a stop but when it does the service engine soon light comes on. Initially I got the P0401 code (I think) and took it in to a mechanic. They could not find anything wrong with the car but did clean out the EGR valve, that didn't work, they worked on my transmission and replaced other parts, still no success.
I took the car to another mechanic who replaced the EGR valve and several other small parts. I still had the problem but this time the error code was P0420. I took it back again and replaced the spark plugs, O/2 sensor, catalytic converter. That hasn't fixed the problem. The mechanic said that they have taken my car for several test drives and the car has not demonstrated the problem. The error message still reads P0420 even after all of the parts have been replaced. The 2nd mechanic has washed his hands of my problem.

I have a slight vibration coming at speeds of 80kph and up that is driving me crazy. The steering wheel doesn"t shake so I am leaning more towards a rear of car issue. The center driveshaft and transmission were replaced and new tires{Conti Extreme Contact DW} Wheels are not bent. The car has 130,000 km"s. The vibe happens mostly when accelerating up freeway ramps. Once the car settles at highway speeds{100_120kph} it tends to reduce to a constant faint shake that you feel in the seats. Rear wheel bearings? CV joints? I am the only one who feels the shaking because I know how smooth a ride it used to be.

My 2003 Buick Century heater works fine while accelerating but as soon as I release the gas the air begins to cool, swiftly. I have had the radiator flushed and the coolant topped off but the problem persists.

My wife's car, a 2003 Buick Century, has died a couple times on her while driving. Each time has been while she was in the midst of a left turn, so I think that is relevant. Today it is a humid, raining off/on kind of day, but she says that she thinks the last time it did it was a dry day. When it dies, she pulls over, puts it in park, and restarts the car, it runs normal, no problems. She said she has turned the ignition switch off, and then starts the car, and has not tried just turning forward to start, however her daughter said that when it died on her, she could not turn it to start - she had to turn it off then back on and it started fine.
Her daughter said that she had it die once while sitting at a traffic light, so I may be off base thinking that it is related to a left turn. The car has about 155K miles on it, and the only engine work that has been done on it other than maintenance is that the catalytic converter was replaced a few years back, when it was plugged up.
On this same car, I have to spray brake cleaner on the ABS sensors (front) about every 3-4 weeks, when the ABS light and the TRAC Off lights come on. Is there some way to keep them from becoming fouled?

My wifes 06 4runner 2wd with 120000 miles on it needed a new battery. I changed the battery that night and my wife called me the next morning when i was at work and told me that her car was idling low with a slight vibration at almost all speeds. Also, when stepping on gas pedal from a dead stop the vehicle hesitates only momentarily and then lurches forward like its slamming into 1st gear and then shifts and drives normally beyond first gear... I am perplexed. Never had any issues with tranny or any other component of the car for that matter until i changed the battery.

I have just over 11K miles on my 2011 and now notice steering wheel vibration & slight shake at 70 mph. The passenger can also feel it.

This has been happening for the past 6 months or so. I recently had new ball joints, 4 wheel alignment, and 4 wheel balance. Even with this I'm noticing a very slight high frequency vibration at highway speeds. I noticed on one of the front wheels that a weight fell off, so this might explain the high speed vibration.
However - When I'm starting at 0mph, and accelerate to say 50mph for example, the car vibrates rather substantially as the speedometer moves from around 25mph to just past 30mph. After those speeds it goes away.
I've also noticed that it tends to be worse if I'm going up hill, which, according to the laws of physics, would tell me that going uphill would put more pressure on the front end, given it's heavier with the engine there. If I'm going downhill it vibrates much less.
When I drive I tend to not accelerate quickly, meaning, I don't 'punch' it, and accelerate gradually instead. If I'm driving on a level, well-paved road, and accelerate quicker than regular, the vibration seems to not be as heavy.
Any other tests for this? Struts, control arm, steering knuckle, drive shaft ?

New, 2 month old 2015 CC, gas 4x4 with standard bed. At 50-55 I have a rolling vibration, or it can even be explained as a slight growl. Seems worse since I upgraded to 285/75/18 Toyo AT's and new wheels. If i speed up to about 60, goes away. If I pop it down to 5th gear, it seems to go away, however, I need to try this a few more times to make certain.

I'm new to Lexus ownership and have recently purchased an 08 certified LS 460 L with the air ride suspension. It's a phenomenal car, I'm now a convert to the brand. One small thing I noticed though is a slight jiggle or vibration coming to the steering wheel at moderate speeds. It is very dependent on the road surface, Seems to dissipate on the highway. Alignment was checked before delivery and feels fine and the tires themselves feel balanced. It's not upsetting, I'm just curious if this is something normal to the air ride suspension. Other than this the car is an absolute gem with only 35,000 miles.

I have a 2000 Buick Century that I cannot get to start. While my wife was driving home it started to sputter (like running out of gas) and did a little back firing. She made it home and I put in some gas (Just to make sure) and the care cranks over but will not start. I have replaced the fuel filter, checked the spark plugs and replaced the CAM Sensor. The car still will not start.

My wife has a 2000 Buick Century with about 150,000 miles on it. It has been relatively trouble free. Recently, the "low coolant" light began to come on.She took the car into a garage where she was told there was oil in the coolant and the sensor had been compromised. The cooling system was flushed and cleaned and a new sensor installed. The "low coolant" light continued to come on. She took the car back in. She was told the wrong sensor had been installed. When she went back for the car the second time, she was told the oil in the coolant was preventing the new sensor from working and there was nothing more the garage could do. I went in and asked questions, primarily how serious was the condition, and couldn't get a straight answer.
We are due to drive to Florida in November. My wife would like to take it to a garage there. Is it save to drive it as is? What are the implications of oil mixing with coolant? What is causing it to happen?

My 03 Buick century is overheating. I changed the thermostat and the water pump. And still overheats as soon As I start driving. I am also getting when it is overheating some misfiring in cylindar 1. I am going to reflush and bleed the coolant even though it seems to be full . i dont think it is disappearing. Is it Possible i have a blown headgasket or intake manifold leak?

I am having a very tricky problem with my Buick.
For approximately the last 4 months, it has been (at least according to the heat gauge on the dash) running pretty hot. Not overheating, but getting close. And it doesn't take long for it to get there. This all seems to have begun right around the time that my father and I flushed the coolant system.
Since then, I have replaced some parts, and learned a few things in the process.
I learned that there are bleeder screws which can be opened to let air bubbles out. And I have heard that the 3.1L is especially susceptible to them.
New parts which I have installed:
- thermostat
- coolant temperature sensor
- radiator cap
- upper radiator hose
- lower radiator hose
I have checked the water pump and it seems to be perfectly fine. No leaks. No signs of bad bearings. And it circulates coolant just fine. I have not been witness to either cooling fan, primary or auxiliary, switching on in a while.
The exact symptoms are these:
The heat gauge does not take long to get to mid-way point, but will sit at that point for a bit if the vehicle remains stationary. Once the vehicle is in significant motion, the heat gauge will climb fairly quickly, especially with moderately high RPMs. It WON'T touch the red though, but will get very very close to it. The car runs fine. It does seem to be a bit underpowered, but I am comparing it to my fiance's 1996 Olds Cutlass Ciera, which I believe has a different transmission. My Buick does not seem to have lost power since this problem arose. The cooling fans no longer kick on. The oil appears fine. The coolant as well. With the radiator cap off, coolant does not bubble out or shoot out.
I made sure after changing upper and lower hoses to fill the radiator, let the car run long enough for the thermostat to open, and then slowly poured more coolant into the radiator until it was full again. And the reservoir is at proper level and the the reservoir hose s not clogged.
I am not SURE, but I don't believe the radiator is clogged. I believe that covers it, at least as well as I can.
BTW, I do not know where the fan relays are, otherwise I would test the fans to see if they still work.
What the heck is up with my Buick? Also, it has 97,xxx miles on it, and the transmission fluid is at proper level and looks normal.

2002 Buick century will sometimes not start. Seems to correlate with warmer weather and happens after long drives. I try to restart within 10 minutes of turning off and it will start and then in a few seconds the car shakes and the engine dies. I can restart multiple times, but it will always die in a couple of seconds. If I wait an hour and retry, no problem. Once someone banged on the gas tank and that solved it. Mechanic cannot diagnose problem unless it dies while he is there. Should I replace the fuel pump or could it be something else?

My grandpa's old wood paneled station wagon is sick. The idle seems to be getting rougher and rougher with every time I kill the battery (I've somehow left my headlights on four times in the past two months and needed a jump). It's to a point now where if I don't throw it in neutral at stop lights and keep a tiny bit of gas on the engine it stalls out.
Notes:*When it first gets jumped after being dead, if I stop even for a second, it dies instantly.*While cruising - it is fine. *It idles smoother stopped in neutral than it does stopped and in drive. *It seems a bit rougher with the engine is cold, but still rough and can stall with the engine hot. *Some random times it idles just fine (like for example the first few seconds on start up, and then it sounds like the engine is decreasing in rpm automatically, and then it is rough again).
Could the dying battery and rough idle be related?? The battery guy says "if it starts fine, the battery is fine" (it does start fine, although keeping the radio on for 20 minutes without it running will kill it).
Also other problems with my car in case this has anything to do with it: *I have a leaky tail pipe*my ABS has recently been randomly engaging at low speeds (next problem to work on...)

I have a 2001 Buick Century that started making a noise from what seems to be the engine. It sounds like a jet engine when I accelerate. The noise is still there when I cruise, but it evens out. It is loudest when going between 40 and 50mph. The car is not overheating, and other then the noise it drives fine. My husband at first thought it sounded like the catalytic converter had been stolen, but he rarely knows what he is talking about. What could it be?

Most of the time it has no problem what-so-ever, but once in a while it just doesn't start. It will turn over and over but that's it. Most of the time if I just let it sit for a few minutes (5-20) it will start right up no problem, but I've noticed when it does it often revs up as if I had my foot on the gas. (that took me a while to realize since I often touch the gas anyway.) Once it's running it runs great. The idle settles down to normal after a few seconds and the car runs as if there was no issue. It does this randomly.
I can drive it for days or hours with no problem, and then suddenly it just decides to leave me stranded. Usually i wait and it gets me home, but a couple times it didn't. I've drained the battery twice on two different occasions months apart trying it, and waiting and trying it. Both times with barely enough juice the following day to turn it over, it fired right up, rev'd the engine, then ran fine. I don't think it's an issue with fuel because on one occasion while trying to start it I laid into the peddle until I could smell gas under the hood- and it never has issue while running, only on start-up.
So far the only thing I've done is replace the spark plugs- it runs better now, but doesn't start any differently.
