    I have a 2004 Buick Rainier that I enjoy alot. The problem that I'm having is my right rear is sagging and the 2 dealerships that I have taken it to have told me that this is normal. I have expressed my concerns and I have pointed out that it was not like this when I first purchased the Buick. Both dealerships have told me that it is within GM specs. and that there is nothing else they can do. I have replaced both leveling sensors( the one on the right side and then the one on the left side). Please any advice would be greatly appreciated. Its not real bad but it is noticable. Thank you.

    It is about 1/2 inch to an inch lower on the right side even when the vehicle is running and the air compressor kicks on, it still sets about 1/2 inch lower on the right side. But the driver side never moves up or goes down, it stay's about the same.

    Could it be the suspensions????
  • richslumsrichslums Posts: 12
    I have the same problem, try leaving the car in neutral when you start the car, for some reason thats when i hear the air thingy move up and down, also, try putting some weight on both sides so that the weight sensors tell the air thingy to adjust. Fixed my problem. People and auto parts people told me i might need new suspensions but uhhh yeah id rather not right now since i would have to change all four..Good Luck!

    Do you mean could it be the sensors?

    Interesting to hear about the sagging. I haven't experienced it on mine yet. Anyone had a strange 'thud' when stationary, especially when car is cold. Almost as if the car behind has tapped the bumper,

    My 2004 Rainier also sags on the right rear side by 0.75 inch. It has done this since the day I bought it brand new. Now have 62,000 miles. I complained to the dealer a number of times about this while it was still in warranty. Got the same stonewall reply that this is normal or within mfg. specs. [non-permissible content removed]. I have watched other Rainiers on the highway and some show the same sag and some don't. Have also noticed this on some Trailblazers. No surprise there since these vehicles (and the Envoy) were all made on the same assembly line. So I have seen these vehicles with no sag, or sagging on the right rear, but I have never seen one sagging on the left side. I don't think this sag is related to the air suspension system because I do not see any change in the vehicle orientation before or after the compressor runs. I suspect the problem has to do with inconsistent suspension components or inconsistent assembly procedures, therefore this is a defect. This is the same cop out that GM has been trying to get away with on the speedometers in the insturment clusters. There have been a lot of failures in these SUV's and some trucks. They should have issued a recall to fix those but instead they tried sticking the owner with paying for that repair. With an attitude like that do they seriously think we would consider purchasing an Enclave someday?

    Doe's anyone know if you can change the rear air ride out with a regular Trailblazer suspension. Because from what I can tell you should be able to you would just have to change out the air bags with a factory (Trailblazer) heavy duty spring for each side and then disconnect the air leveling sensors. Please any feed back would be helpful. Because at this point I don't care for the air ride I just won't my vehicle to sit level.

    Yeah i hear a thud but it feels like it comes from the engine or passengers side floor i think..I was told it could be two things. The engine. Or the truck shifting from four wheel drive to two wheel drive?? idk got me..Could mean oil change or something..If you live in the city like new york there are alot of pot holes, so my truck shifts into four wheel drive alot and back to normal, could be that too...just a thought..its what i was told and it does make some sense, but im no expert lol
  • I have a 2004 Buick Ranier that has a tendancy to stall. It may not happen but, once a week or month. I'll just start it right back up. Taken it to repair shop, put on computor with no luck. I have heard that it could be the tourque converter solnoid. Anyone ever have this problem?
  • icemaniceman Posts: 21
    Yes I am currently having the same problem with mine and I have taken it to the dealership with little luck. Mine finally had set off a code saying it was the 02 sensor. So that part is on order and they are going to replace that part and hopefully it will fix the problem but I doubt it. This has been an ongoing problem for me for quiet a while. If you or any else knows how to fix this problem please post the "cure". Thank You.
  • I also had the check engine light come on and everything pointed to the O2 sensor. I changed it out myself for approx. $56.00 and so far so good. Not to difficult to change. Will keep you informed.
  • icemaniceman Posts: 21
    Thanks for the response hopefully that takes care of the problem. Please keep me informed.

    Has anyone experienced a thud type of noise around 25 MPH on the 2004 Buick Rainier AWD and then around 30-35 MPH a studdering motion occurs. The dealer is looking into the problem but tells me the technical advice he received from GM is that it might be due to worn tires. The tires are not worn and this does not sound like it would be the problem. Has anyone else experienced these problems?
  • In Dec '08 while pulling up to a stop sign, my Rainier experienced a severe "clunk" which shook the SUV and then a burning smell developed. I pulled off the road & had it towed to the dealer because the smell was so bad. Turned out the front differential had to be replaced to the tune of over $2,000. The dealer footed the bill since I had brought it in twice that year for differential issues. It's now 30,000 miles later and guess what...the differential needs to be replaced again and neither the dealer nor Buick is willing to pony up. I can't afford $2,500 repairs every 30,000 miles. Anyone else experiencing differential issues or am I just that unlucky? All recommended service work was performed in the interim...
  • I have a 2004 Buick Ranier with the same problem and I checked with United Speedometer in Houston, Texas and they advised repair 1/2 day and $425.00
    They said as it gets worse the other gauges will also have a problem with.
    I can start the engine and turn it off several times and this will bring the speedometer to "0".

    Hi, I have a 2004 Rainier CXL with AWD. How can I tell if the AWD is working or not? Up here in Michigan I slide all over the road and never seem to hear or feel the front wheels engage. And I do not get any activation lights coming on either. Maybe it is just not working.
    Thanks

  • Well I think the best way is to burn out with snow lol or take it to a dealer.

    I own a 2004 Rainier and noticed there were a lot of responses to this issue I am replying to. I also have this problem. I actually couldn't afford what I was told would fix the problem and have been driving by the rpm's. My speedo started off registering really high when I was just accelerating. If it was suppose to be at zero, it would be maybe at 60 or lower, or higher. Then, eventually it would not work at all. Once in a while it would work, but most of the time it was not moving at all. This has been going on for a 1 1/2 yrs now. My vehicle is litterally falling apart. My front diff is also done and has been replaced. My rear needs to be replaced. My fuel gauge is messed up and now doesn't work. My oil gauge now doesn't work. My CD is stuck in my player. These issues have all been discussed on various forums. I am glad they are no longer making this vehicle, but it did make me never want to go to Buick ever again. I am currently looking for a new SUV now that I think something happened to my fueling system or transmission. I'm going to look on the forums to see if anyone else has the issue. I bought it used and it's now at 107k miles. This vehicle has cost me a fortune and I'm done with it. :mad: :lemon: :sick:
  • Hi a_mac,
    I own a 2004 Rainier myself and live in Michigan as well!! Worst place to not have your AWD.
    You'll know when your AWD is responding because your steering will feel "tighter", and the Rainier feels likes it's "stiff". I just got mine back from the shop b/c it needed the TCCM replaced (440.00 repair) Mine wasn't reading correctly so there for it was stuck in AWD. If I were you I'd take it in and have it looked at. Generaly you know when it's in AWD and if it does do it there could be lots of problems. Supposedly they have issues with the DIFFS leaking and ultimately burning it up...................Good Luck

    I don't know about the speed indicator but the fuel gage being gone usually means your fuel pump is getting ready to dump on you!!! This will leave you stranded when ever it finally finishes.

  • My 2005 Buick Rainier V6 has a check engine light SU176 Secondary Air Injection Solenoid engine sensor error. I was told the solenoid is bad and needs to be replaced. Do I need to have this replaced? Is this going to affect my vehicle's performance? Will I be able to drive the car? Does this only impact emissions? Is this a necessary element of the engine?

    Additionally, I had the panel gauge issues as mentioned and had to have my speed odom panel replaced. So yes, this is a Buick defect that should be a recall.

    I also have the thumping feeling when I am at a stop light. Like someone tapped my bumper from behind. I guess that is another Buick defect that should be recalled. Wow, wish I would have known these things before deciding to by it. :lemon:
  • How did your Rainier act when it was locked in four wheel drive. I was told mine is locked in and it shudders and shakes when I turn slow left and right turns. Engine runs rough too. It goes fine straight down the road.
  • I didn't have an issue with it being locked in four wheel drive. My issue is when I am at a stop light, I get a "bang" action that feels like someone tapped into my bumper even though nobody did. It is a quick jerking action. No engine issues or loss of power.

    My 2004 Rainier has 55k and has been a good vehicle. The problem is a grinding/clunking noise from the front end and vibration in the steering wheel when turning left. It does not make the noise until the vehicle has been driven for about 5 minutes. It has been doing this for the last year and nobody has been able to fix it. Since my extended warranty ends soon, I brought it to my local Buick dealer. They proceeded to replace the front differential with a used unit, but it did not fix the problem. If anything, it is moderately worse.

    Now the dealer says the issue is inherent to the all wheel drive system and is not uncommon. Has anyone experienced this issue? They are saying the system is performing as it should. It did not make the noise for the first 50k miles, so I am still concerned.

    Any suggestions?

    I had a similar problem but the clunk vibration was eventually occured both when tturning sharp left or right. It felt like it was binding up. I finally took it in and it was the transfer case, middle box, that went bad. It locks into four wheel drive all tme. You only notice it when turning. Cost was 2300.00. It definetly solved the problem.

    Im having the same issue. Its a thump sound on my right passenger floor it seems like. It happens every 10 to 15 seconds or so. Its louder when i turn on the car for the first time in the day, during the day it get lower but still noticeable. I think it could be a rat or something up there lol jk i dont know much about cars, but i do know i need new tie rods and something for my axel which makes noise in the back, maybe these could be the problem?? i have a buick rainier 2004 70,000 awd v8 5.3 L...about the 4x4 or awd going into gear, i live in the city where theres a bunch of pot holes, i was told my truck would switch to awd due to the many bumpy roads, could be the problem for the thump or any other tugs or sounds,.
    I just hope i dont have to get a new transfer case like the post many before me he paid 2,300 for it, oh hellz no lol
  • richslumsrichslums Posts: 12
    Also for those that had problems turning etc and hearing noise i had the same problem, i went for an oil change and they changed my power steering , put some kind of kit, changed or added some fluid to my transmission oil, and now i dont have turning noises, might be able to fix some of your guys problems i have read above...
