    You might want to stop by the Speed Shop: Tuning & Modification board.

    The dealer tore apart the trannie and found damage. Something about a clutch plate starting to fail. Anyway to the guy who posted the original message your transmission is on its way out. The dealer is replacing mine under my extended warranty. The service tech gave my old transmission maybe 6 to 12 months before it failed totally.
  • Wondering if anyone else has had this issue and what was done to correct it, the warning lights for ABS, Traction Control, Brakes, and Service Vehicle soon all come on. We have had it in twice now to fix this issue and its happened again. This is what they told me they fixed , WIRING AND/OR CONNECTOR - BRAKE SYSTEM/TRACTION CONTROL , the last time and before that HARNESS, WHEEL SPEED SENSOR JUMPER WIRING (ABS) - REAR - B,
  • I am looking to buy a used alero (2000) 2.4 liter, this car has the same problem you are describing, so the guy is willing to sell it really cheap (that is why I am intersted) I was wondering if you could tell me a little more about this problem and possibly the costs involved in fixing it. I was looking at buying this car, trying to resolve the issue and selling it again for alot more $$$. Is this a computer problem in the car or just a matter of nuts and bolts and a new sensor? Also, does the abs then not actually function, or does the light just go on? Please tell me as much as you know about it, anyone else please feel free to contribute as well!! Thanks.
  • My 2000 Alero (81,000) has been making this sound off and on for the past year. The sound is like a clunking sound. It happens after turning and accelerating and also when accelerating from standstill without turning. The 2 dealerships I have taken it to cannot replicate the problem. First time, a Pontiac dealership said pads were worn and replaced them... problem seemed to disappear for awhile. Came back. Back to the same Pontiac delarership... somehow me explaining to the "service advisor," that it clunks when i turn, turned into the mechanic hearing it clunks when i drive over a bumps. So front struts and mounts were replaced. After I drove away from the dealership, within 5 minutes the noise occured again. It happended 2 times on the way back. The mechanic rode with me, but it didn't happen again. A few months go by... seemed to have disappeared. Then 2 weeks ago, when raining and 2 other people in the car, it happened constantly after turning and accelerating and accelerating in a straight line. A friend who has never experienced it was scared. After a week of not driving it, took it to a Chevrolet dealership 3 blocks me. They could not replicate the problem. I also had mentioned to them that with just sitting in the car while running, turning the wheel left or right, there was a faint sound and feel when the wheel is turned back to the center. I didn't know if i was opening a new can of worns or trying to be helpful. They diagnosed that as being worn steering gear and worn intermedant shaft... quote $1600. They said since they could not replicate the noise/ clunk I was talking about, they couldn't say if spending the $1600 would fix it. After leavingt he Chevy dealership it did it down the road... has been doing it daily, but not every turn or accleration. It's not just the clunking sound, you can feel it in the body. My front passenger can feel and hear it. You don't feel it in the steering wheel. I've read previous posts that had mentioned the struts, which were replaced for about $1200 (the car now feels more substantial over uneven roads). Could it be the CV joints? Anyone have any ideas. Oh, there's an Olds dealership which is much further away then the rest, that'll probably end up taking it to.
  • I had to replace the ignition switch and tumbler on a 2001 Olds Alero and now the car will not start and the security light is on!

    How do I reset the system to recongize the new switch???

    There are several posts a few pages back addressing security issues; if you do a search for "security" in this forum, you'll find lots of posts addressing this problem. Reading some of those posts, I have a feeling you may have to take it in and have a service centre reset the system. Here's what our owner's manual says about the Passlock system:

    If the engine stalls and the SECURITY light flashes, wait until the light stops flashing before trying to restart the engine. Remember to release the key from START as soon as the engine starts.

    If the engine is running and the SECURITY light comes on, you will be able to restart the engine if you turn the engine off. However, your Passlock system is not working properly and must be serviced by your dealer. Your vehicle is not protected by Passlock at this time. You may also want to check the fuse. See your dealer for service.
  • My 2000 Alero (3.4L V6, 98,500mi) is acting strange. While I was driving with the cruise set on 72, the RPM gauge went from around 2500 to less than 1000, and the cruise shut off (obviously). When I pressed the accelerator, absolutely nothing happened. At first I thought the transmission had slipped or something, but the engine didn't rev up (and the RPM gauge needle didn't move) when I pressed the gas pedal. The car was completely unresponsive, but the engine did not shut off. No warning lights came on at all. So, as I am gradually slowing down, I pulled to the side of the road. I decided to try the gas pedal one more time (after pressing it several times to no avail), and the car decided that it wanted to go. I was able to accelerate like nothing had happened. Then after about 30 miles, it did it again, several more times. On the third time, I slowed to a complete stop, and the engine died this time. It took 3 tries to get it to crank. I went a few more miles, and the engine felt like it was misfiring or something (it was really rough). The car died again, and I had to sit there for a few minutes before it would crank again.

    Has anyone else had this problem? If so, how'd you fix it? I've had several mechanics tell me that it was really weird that the engine did not shut off (or at least shut off right only shut off on me twice, but I had to pull to the side of the road about 6 times total). Could it be electrical or fuel related? Thanks!
  • burdawgburdawg Posts: 1,524
    My first place to look would be at the fuel pump/filter. The symptoms you describe are classic signs of an electric pump that is starting to fail.
  • thanks bunches! I'll check into that.
  • I'm having some of the same problems with my Olds Alero 2001 3.4L 100K (just turned). It lost power twice during one trip, but never died. Then on a second trip a week later it stalled. Both times I was going about 70 down the highway. Wasn't trying to pass or do anything else out of the ordinary. I changed the plugs/wires, and used a couple bottles of STP fuel injector cleaner, plus some gas cleaner. Now (3 weeks later) it won't start. I can hear the fuel pump engage (small hum under the back seat) and I have over half a tank of gas.

    My current thoughts are (in order):
    - Clogged filter
    - Clogged fuel injectors

    Just curious if you've already resolved this issue and what the problem ended up being.

    Since I made it through the spark plug change without any problems I was going to try and fix this on my own... Changing the filter first (attempting to start), then changing the fuel injectors if that didn't work.

  • They replaced the main computer now and a month later, the lights all just came on again. So back into the garage it goes this will be the 4th time.
  • My daughter has a 03 Alero with the same problem.. a "clunking" sound from the passenger front corner of the car. She lives a considerable distance away and will be coming home soon for a short visit and has asked me to figure out the problem. I need your have tried a number of "fixes" but, have you been able to determine the root of the problem? HELP!!!
  • Hello, I have a 2002 Alero GLS 4 cyl with about 77K miles. A couple of weeks ago I stopped at the store and when I returned it wouldn't start. It just kept spinning over. I had it towed to a mechanics shop that day, Saturday, and he wasn't going to be able to get to it until Monday. When he went out to look at it Monday morning, it started up just fine. Well, now it is doing it again. It runs great and there are no problems at all with it (except this, obviously). When it does this, there are no hints beforehand as all the gauges work fine and it runs like a top. Any ideas... please help!
  • When applying the brakes on our 2003-low mileage Alero, there seems to be a "groan" coming from the passenger front wheel area. Anyone have any ideas on what the problem might be and how to fix the problem?
  • This sounds like a possible brake problem, but if it's only intermittent--say, it happens only first thing in the morning--then it's probably a "normal" sound. But if it happens all the time, then you might want to get your brakes checked out. Here's a page that outlines some of these sounds: Disc Brake Noises

    Here's another service bulletin which goes into various brake noises (squeaks, squeals, clunks or groans). It's for Nissan, but should apply to most other makes and models, too: Nissan Brake Noises
  • I am far from being a mechanic. Still having the problem and have not determined the cause. I did take it to another place, a Firestone- Mastercare place for a "complete vehicle inspection" for $20. They said they were able to re- create the sound/ "pulsation/vibration". They said nothing about the steering gear that the Chevy dealership thought it might be but couldn't guarantee. Firestone thought it could be the wheel bearings or some part of the transaxle, but said that they thought the wheel bearings seemed FINE. They quoted $500 for both but couldn't guarantee that it would fix it. I did not have them replaced. Oddly, since having the car back for the past few days it hasn't occured when turning, but now only when accelerating in a straight line. I've also noticed it happens after I have driven it for atleast 15 minutes or more. For some reason I'm thinking it might be my rotors. My car brakes fine but earlier this year i had new brake pads and the rotors machined and it seemed to disappear for a few months. My rotors probably have 50k on them so maybe it's time to replace. I'll probably do it myself within the next few weeks. If that "cures" it I'll post a message. If you figure it out, tell me.
  • From your description of when the sound occurs this does NOT sound like a typical wheel bearing noise. "Classically" the sound of a worn wheel bearing is louder when you turn the wheel off center, and that was exactly what our mechanic tested for on the road test when our wheel bearings went.
  • I found the solution to the problem. In fact it is a very common problem with the Alero and Grand Am. The mechanic told me that they really should have recalled the part.
    The problem is a little 'sock' filter that is on the fuel pump. It's poorly designed/constructed; when it gets really dirty, it tends to stick together under high pressures. From my understanding the sock is designed to block miniscule particles. Well, when the pressure causes the sock to collapse, the engine may or may not get enough fuel to remain running. All of this is why the problem is intermittent. Once the pressure drops enough, the sock will open back up, and the car will run as though there was no problem.
    I may be wrong, but I think you can just have the sock filter replaced. It's funny...GM knew there was a problem; the replacement part is textured (the old part is not) to create a little friction so that it is less likely to stick together. I went ahead and replaced the whole fuel pump because my fuel gauge sensor was bad (for the second time). I had to keep up with my mileage to know how much gas I had.
    Anyway, hope this helps!
  • I have a 2000 alero with a 4 cyl the check eng lite came on so i took it up to auto zone and pulled the code said it was a miss fire on the # 4cyl so he said to replace the plugs and the boots so i did and i un hooked the battery to clear the codes (they told me to do that ) the light went off but coming home form work the next day it came back on went back to auto zone same code was pulled .. does anyone know what else i might look at ?

    Thank You :sick:
  • The "Clunking Noise" seems to be an epic story! Let us know what they find at the Olds dealership down the road. What do you think it is?
  • The epic ended for me. I no longer have the car. I never took it to Olds. I have no idea what could have been causing it.
  • The news is GOOD on the 2003 w/30K miles. My daughter took the car to a GM dealership in Charleston, SC and they replaced a broken strut, checked out the brake area and aligned the front wheels at NO COST!! They said it was still under warranty until April 06. WOW!
  • Mikey00,At the time of the comparison was the 2000/2001 Consumer reports online. I'm sure in 5 years all the " litle things" have finally surfaced that would on any American car and slowly degrade the comparison to the Japanese. So the comparison was with that data when I bought it. One thing I have noticed from Consumer reports is that data changes over the years on car ratings as the models show their true worth. That said, I think there is a natural negative bias towards discontinued models and model changeovers.

    I still like my Alero and now let the 16 year old take it around locally. I'm going to get a motorcycle next as $3.00 a gallon in CA was too much. The Hybrids cars have higher insurance at this point so I'm going for something that gets 40-50 mpg. has some interesting models electric hybrids that get 50-60 mpg.

    I'm still considering a last year 2004 Alero if they are still around with low mileage!
  • burdawgburdawg Posts: 1,524
    Take a hard look at the hybrids before jumping on that wagon. I've read where some folks aren't getting the mileage they expected or was advertised.
    I didn't like the $3.00/gallon in CA either, but one thing I noticed was a lot less traffic when the prices were high.

    We have a 99 Alero low miles and we had the same noise. After replacing the wheel bearings twice and buying new tires twice in under a year, we installed ceramic brake pads and the noise has gone away. The car stops better than before. It was well worth the $60. Hope this helps!
  • :cry: This has not been a good Thanksgiving weekend for me. I woke up Thursday morning to drive home from a friend's place, and found that my car was not running properly. It would start, but would not accelerate at any reasonable speed. Imangine taking five minutes to get up to 30mph on the road...just not great. I thought that maybe at the time I just had not warmed up the car (which I should never have to do living in Florida) beacuse it was a little "chilly" that day, maybe it just needed gas which I stopped for first thing. After going through my day (work, then to mom's, then out for drinks) the car ran fine and the "Servive Engine Soon" and "Low Trac" lights all turned off. Parked my car Thursday night and did not drive again till Friday night...when the problem came back. The lights back on and car refusing to accelerate and run properly. I thought then to check the oil and such and maybe that it was a "warm-up" problem that had suddenly came on. So Saturday daytime I warmed it up and looked under the hood for a bit to find it AGAIN behaving normal afer maybe 20-30 minutes. Then the fun happened late Saturday night when pulling into my place to sleep...lights back on and car back to not running! AAAAGGGGHHHHHH!!!!! :mad: Good thing I have a friend who knows a little about cars like how to check all fluids and such, so she got under my hood today and checked it out. Thought maybe the transmission fluid was low, which would maybe explain why it didn't accelerate. After leaving her place though the car did not get better...and found me driving back to mom's then to work today feeling like a little old grandmother with angry drivers behind me screaming. I have looked everywhere I can think of in the car, and also online for help. Unfortunately there are not even sites that will map out the engine for you of the Alero or that answer any questions. What do I do though??? :confuse: My car is not able to go any sort of speed, and I have bacically been throwing away money just to go from one place to another due to how fast the gas is going from trying to rev the engine. RPM's will increase...but car moves slowly!
    :sick:By the way this is the 99 Alero V6 Twin Cam Engine with just over 100K. Owned for maybe three months. I had just had an oil change maybe two weeks ago.

    Sounds as a transmission problem to me. Had 98 Malibu, with similar transmission. It slipped when it was cold, but run OK when warm. Or I thought so.

    Dealer replaced the transmission - fortunately, then I had an extended warranty. Turned to be, that with healthy transmission the car accelerated much better when warm too.

    Low transmission fluid demonstrates the same symptoms. I know it because had a 88 Taurus with a leaky transmission hose. However, with Malibu transmission, it is impossible to check fluid level. Only mechanic can do it. and with The same with Alero if I understand it right...
