    My wife's Buick Ranier has problems with the speedometer and oil pressure gauge. THis developed years ago and the dealer was never able to resolve this. She is now looking for a new car and refuses to consider any of the GM cars. Really sad to hear this was such a chronic problem. Sad way for such a historically strong company to die.

    My warranty was bought from the car dealer. It was from a company called Zurich. I have no complaints about them. My Buick was hit while parked and totaled by the insurance company, this year. I'm glad they survived, for the sake of the workers, but I wont buy GM again. My Subaru Outback gets very good marks on reliability and quality as well as good mpg and all important in my region all wheel drive. it as built in the state of Indiana.
  • Good thing I researched this. When I first bought this car, I had problems with the speedometer. Fortunately, I had an extended warranty and I finally got it fixed. A month later, and now all of the gauges have gone wacko all of a sudden. So, I am taking it back tomorrow to see what the problem is. And hopefully, my warranty will cover it!!

    Will keep you posted on the outcome. I planned to refinance it so that it would be paid off faster. Best believe I will be trading it in....
  • No speedometer probs yet. Have a problem with dead battery. Runs down after 1 day if left undriven. Something draining it.Short? Battery bounces right back once I get it restarted. It might be the air shock system?
    Any help or advice would be welcome

  • Took it in today, they could not diagnose the problem, so they removed the battery and recharged it, and it worked fine. So,,, I foresee that this is going to be a recurring issue. Definitely confirmed my decision to trade it in for a Honda Accord once it's paid off. Good riddance haha.
  • Not sure what that could be, that sounds odd. It's ironic because my battery died this morning, and the AAA man ran a test, bad battery, needed replaced. Once he replaced it, my speedomoter and gauges are working properly. SN: Oh yes after getting the speedo fixed for the 2nd time they went haywire again, the next day. I let it sit for about 3 days because it was my intent to take it to the dealer again, but when I went to start it, no action. Must have been divine intervention lol.

    The AAA man also suspected the alternator was bad (but after testing it, it was fine).

    I would suggest going to get your batter, starter, and your alternator tested, that could be the root of the problem.
  • Hello, my issue is my 2004 Buick Rainier CXL has just recently shut off on me. For many weeks it has driven good but out of no where it would shut off on me. When it shuts off, my dash board computer says Service Break System and my sensor break lights on my dash turn on. It has been an issue for the last couple of weeks until it recently just shut off completley. Now, it wont turn back on. Everytime I turn the key to start it, it keeps beeping and the same message reads, Service Break System on my dashboard. I was told it could be the relay fuse and I put a new one in but it didnt work. I need HELP PLEASE!!!!
  • One day last week my low beams stopped working. I thought I needed a new bulb. So I bought 2 new bulbs and found that there was nothing wrong with the bulbs. I then got the OM meter and I tested every fuse in that thing. They wre all good.So I turned to switches. Maybe it was a bad headlamp switch, or dimer switch. I thought I found the problem. Well when I went to get this switch ( I can't think of the name of it, but it's on the left side of the steering, it allows you to turn your headlights off..) the dealer said it could be that sensor that is in the middle of your dashboard. A light sensor. Well now I am back to square one. What the hell can the problem be ?There is so much electronics in this vehicle that it's almost impossible to find what is wrong. Can you help ?
  • I would love to join you in that fight. I belive that they do know about this/these problems and do not want to admit it or tell anyone because they know that they'ed have to replace /or fix these problems or do a massive recall. I like my Rainier but I can't afford the dealers cost to fix it. Talk to me........

  • I have an 04 Rainier. I bought it about a year ago. On my way home from the dealership, the speedometer quit working. It showed that I was going 100mph when I was only going 20-25. Then it dropped to 0 and didn't move again. I immediately called the dealership and talk to the tech. He said that the guy traded it in because he didn't want to pay the cost to fix it. I was shocked that they knew it was messed up and sold it anyway. He told me that it should have been fixed and to bring it in the following business day and they would check it out for me. I took it in and was told it would be $1700 for all the part and labor. They said the whole panel had to be replaced. I went straight to the salesperson and she said she would take care of it and the company would replace it at no charge. They ordered the part and when I took it back in the Manager told me that i would have to pay half. I told him I wasn't paying a dime and he could keep it. They finally fixed it at no charge but informed me that they couldn't be expected to fix everyones vehicle.
    My headlights also flicker. One night they went out completely on dim and I had to drive home bright lighting everyone. I put a new battery in and there is no change. Today my gearshifter messed up. The shifter cable broke. I'm waiting on a replacement from the auto parts store. Has anyone else had this problem?

    Were you planning on having the vehicle diagnosed by a GM dealership? Please keep me posted on any information.

    Thank you,
    Caron, GM Customer Service

    04 Rainier
    1 owner (me)
    Little over 100k
    Never again will I Buy a Buick

    Bought it with 110 miles. Bought the extended warranty (ended at 100k). In November 2012 the gear shift cable broke. 7 1/2 months pregnant. Drove it to the doctor's office then stopped at a dealership to get the inspection sticker. They were unable to move it as the cable clamps broke. The clamps are made of plastic and exposed to weather without any protection. The dearlship was able to test it & guess what IT PASS!!! How does a major cable brake, prevents the vehicle from moving but still passes an inspection. BECAUSE THAT CABLE DOES NOT CAUSE THE CHECK ENGINE LIGHT TO TURN ON. Contacted GM and as everyone else on here & all other forums, after knowing your vehicle is over 100K, its oh well your problem not ours!!!
    My main concern was, what else can malfunction (& make it unsafe) and not cause the check engine light to turn on. When I called a Buick dealership, they said you have to bring it in so we can hook it up and see what is the problem. I was furious, I'm telling you what needs to be replaced (another mechanic from a Honda dealership) & NO CHECK ENGINE LIGHT IS ON!!! Finally said it would be $400. Fixed it, what else could I do with a baby on the way.
    The waterpump acting up. Changed it $500.

    NOW, fuse ING E keeps blowing.

    Driver vent blows cold air while the passanger blows hot air. And yes I have checked the temperature and also changed the mode to the dual setting.

    RMP gauge is not working properly, its unstable while driving. When I press on the gas it goes from 1.5 to 2.5 back and forth, unstable.

    Sounds like it wants to cut off (which at times it has while waiting in line at a drive thru, red light ect.)

    Has a rough kick when the ac it turned on.

    Buick I understand vehicles will not last forever. But your vehicles only last to 100K, you should inform potential clients of that defect. I WOULD NOT HAVE BOUGHT ONE, HAD I KNOWN. I also own a 06 Honda Accord (170K) which runs like new, 02 Sequoia (115K) no major issues except to replace the normal wear and tear stuff.

    Today I will be looking for another SUV, IT WILL NOT BE A BUICK. Any make but yours. I have told everyone I know to not through their money away with buying any Buick vehicle.


    Potential buyers: YOU HAVE BEEN WARN!!!! MANY OF US WENT WARN, BUICK IS NOT WORTH THE MONEY UNLESS YOU WANT A VEHICLE FOR LESS THAN 100K!!!! Take your money and run from ALL Buick dealerships!!!!!
