    VEHICLES MAY EXPERIENCE SHAKE / VIBRATION IN STEERING WHEEL, FLOOR, SEAT AT HIGHWAY SPEEDS ON SMOOTH ROADS.
  • My 2001 has had the tire disturbance since I have had it, but unfortunately this is a very common and difficult problem on all "G" bodies since they were introduced. They experience extreme sensitivity to tire uniformity and unbalance. It is a complex issue of bushing rates, spring rates, control arm mass, etc.--in other words it is design issue that while improved since the 1995 models, is still not resolved. I have had mine in 3 times now and am still not happy. It takes a finely calibrated balancer at a minimum, but generally a special machine which measures force variation (some better tire companies have them) in order to reduce the problem to acceptable levels.

    I have not experienced the vibration problem in either my 2001 or 2002 Aurora 4.0L models. The 2001 went as high as 110 MPH, and I have cruised the 2002 at 85 MPH with no sign of wobble. What I can say is that because my cars have not had this problem (and the TSB proves that it exists) there must be some combination of parts & setup that solves the problem. Keep pestering your dealer and GM to find a complete, permanent fix.
  • I'm considering buying an 97 Aurora. It has 80400 miles on it ..It's loaded! The deal is I would get it for 5000.00 because it sometimes stalls at speeds around 30mph, it's been to the dealers and they cant figure it out. It only does it maybe 2x a week. This car is in superior condition and no other problems. Does anyone have ANY info on this, the dealer hooked a computer and left it in to figure it out but couldn't fix it. I know they've replaced the fuel filter. When occurring it can be placed in N and re started immediately. theres no other signs...you cant even tell it stalled until you give gas and nothing. At the price I will pay ..if I can get it fixed (reasonably) I think Im getting a great deal.

    Possibly the fuel pressure regulator, or maybe the EGR valve (a couple of the common Aurora failures reported on the Sedans board back in earlier posts).

    We really need a FAQ on repairs. Wish I had time, but, with layoffs at my work, I'm busier than ever.

    Has anyone noticed on their 2002 or maybe 2001 that the shift from 1st to 2nd is a bit hard sometimes? It tends to be in light-throttle shifting. I think I will take it in, but I hate leaving my car at the dealer.

    I have a 2000 Bonneville SSEi, which as you may know is, along with the LeSabre, based on the same platform as the Aurora. I and a number of other owners have also had vibration problems similar to what some of you have reported. Mine has done it since new. Shakes at highway speeds, through the steering wheel, seats, and floor. I waited for awhile to see what knowledge I could glean from the Edmunds' forums before taking it in to the dealer armed with something to ask/look for. Everyone else seems very frustrated that the dealers can't fix this problem. No amount of wheel balancing, tire replacement or other tricks seem to work. Finally one poster claimed that the hubs had a manufacturing defect where the stud runout was out of tolerance, which would make the wheel "wobble" in an oval rather than circular spin.
    Today I finally had the dealer take a look at it. I specifically asked them to check the stud runout, but they didn't. Instead they balanced all four wheels and proclaimed the vibration gone. Well, it seems much better, but I'm still not convinced the problem is gone entirely. I still sense a shudder as if driving on a washboard surface, but it is very slight and phases in and out. I'm going to drive it for awhile before deciding whether or not this merits more attention. I hate bringing the car in because they usually do a less than spectacular job. Today they lost one of the wheel nut caps, so I need to go back (again) in the morning to either find it or order a new one.
    BTW, those of us over in the Bonneville forum all love our cars and can appreciate how you guys all feel about your Auroras. Just today I saw three new Auroras, a pretty rare thing (just as rare as the Bonnevilles, if not more so).
    Just thought I would share some thoughts about the vibration. Enjoy your rides!
  • I own a '97 Aurora. I have a love/hate relationship with the car. I have had many many problems with the car including stalling. I brought it to my local dealer at least 8 times. They did everything from tune ups, o2 sensors, etc. nothing worked.

    Finally the owner of the dealership said that he had received a memo from GM reminding all dealers NOT to recommend high octane gas for their cars. As luck would have it, I always put the best gas I could find in the car. Since I stopped using high octane gas, the problems have esentally disappeared.

    Of course I recently tried to trade in the car for a new one. All though the book value is over $14,000, I'm being told that it's only worth $5,000 or $6,000.

    Anyone want to buy a nice '97?

    mdearing: Did they ever replace the fuel pressure regulator? That is most often the cause of the stalling. As for premium, the only difference I ever noticed by running regular is slight pinging, a little mpg loss and a noticible power loss. (my problem of lean-throttle engine surge remained with either grade fuel)

  • They may have replaced the regulator. At 50,000 miles they replaced almost every part of the ignition system as well as the fuel system. Nothing worked.

    I guess when you think about it, certain high octane gasolines have so many additives that it's detrimental to these sophisticated systems. For whatever the reason, since switching to low octane, all of my cars are running better.
  • For almost a year the ABS and traction control lights have been on in the Aurora. After $150.00 the dealer simply told me that the brake system was fine.

    I have seen other sights discussing this issue. My guess is there's a sensor or something that's bad. I haven't been able to find any repair manuels or other info to pursue a resolution.

    Any ideas?

    Just had mine fixed. Please see postings in the main board for information that could be useful to you.
  • I have a 2001 3.5 27,000 miles which I bought used and the only problems I have are:

    #1 The A/C blower is loud when on med or high setting (not dual system)

    #2 The headlights seem to blink or get dim while driving at night.
  • hardestyhardesty Posts: 166
    There was a TSB issued in May 2001 regarding a headlight dimming problem (#110501).
  • Hey, my 2001 has that momentary blink of the headlights that seems related to the shift in the transmission--what does that TSB say it is? Just curious because I e-mailed Olds and they haven't answered. Is this a big problem or just an minor thing? You guys are getting me a bit unnerved with my purchase. Oh,yeah, I had the dealer check out the intermittent wipers and it was in the rainsense dohickey on the windshield--apparently, the windshield had been replaced and the wrong kind of glue was used to reattach the sensing device--a kit is ordered! How is that thing supposed to work anyway? Experienced rainsense owners only--is it automatic or does the driver have to activate--yes I have an owners manual but it is unclear.
  • rjs200240rjs200240 Posts: 1,277
    You do have to activate the rainsense wipers. Essentially your wipers have four settings:
    1) Off
    2) Rainsense (instead of intermittent)
    3) Low
    4) High
    (5 could be when you push it down to momentarily activate the wipers while you hold it down)

    When you set it on Rainsense, you can control how sensitive it is by adjusting that ring. This would be where you would adjust the time interval on intermittent-only wipers. The Rainsense takes the place of intermittent and will activate the wipers when it sees "enough" water on the small amount of windshield by the sensor (figuring that if it is wet, the rest of the windshield must be too). By adjusting the ring, you set how much is "enough". They work pretty well, and I like them when it is just misting or the rain comes and goes. I always used to have to mess with the interval on my old intermittent-only car because otherwise the wipers squeaked or there was too much rain on the windshield. The rainsense works like a charm for this.

    As an aside, would you believe my 1987 Corvette had fully adjustable intermittent wipers? I am always suprised at that considering it was 1987, and that most cars still don't have fully adjustable intermittent (many econo and family cars have just one or two intermittent settings) It had ABS too, which was certainly rare then (I beleive only Porsche and the Corvette had them in 1986).
  • My 96 aurora has a steering vibration when I turn, most noticeable when I turn to the right. Changed the power steering pump, the tension pulley and rack, all under warranty. Vibration is less pronounced than it was but still there. Someone said it is the egr, another said it is the harmonic balancer. Any Ideas? Warranty is running out.
  • I had a problem with a '95 engine (3.4l)... a friends car was overheating ( low on antifreeze, actually bone dry ) so i filled the reservoir and the radiator with haveline GM approved long life fluid... started the car and noticed white smoke from the exhaust. Shut off the car, told her she had blown a head gasket or intake manifold gasket and she had it towed to GM dealer. They said that the wrong antifreeze caused more damage. I know if you have the new stuff, you can't add the old. But has anyone heard of the old can't be updated?
  • rjs200240rjs200240 Posts: 1,277
    I don't have any facts on your problem. However, it seems the wrong type of antifreeze would just damage the water pump or possibly cause long-term corrosion of iron components in the engine. However, even straight water wouldn't cause any damage that quickly (except maybe to the water pump because it is a poor lubricant). What sort of "more damage" do they think it caused? I would try to get specifics. If the gasket was blown/damaged, then I would bet it was from running with no coolant, rather than from the later addition of the "wrong" coolant. Plus, doesn't the antifreeze say on the packaging that it is ok to use in any application?

    I suppose if coolant seeped into the intake manifold and then into the combustion chamber once the gasket was bad, it could cause some damage. However, it wouldn't matter what type of coolant it was as it is all incompressible... Just my two cents, though.

    I hope your mechanics were wrong about using the wrong antifreeze, I just had my cooling system flushed and the "red" antifreeze installed in my '95 Aurora. I wanted it to be compatible with my '97 that has the "red" coolant in it from the factory. In fact my bottle of "red" coolant says it is compatible with the "green" coolant. Does anyone know if I can replace my coolant with the "red" coolant? The old coolant was completely drained and flushed. I also had a new thermostat installed, it runs somewhat cooler now on the temp. gauge.
